Summary: Endeavor got struck by a Quirk that physically reduced him to a five year old but (thankfully?) left his mentality untouched. Unfortunately for him, he is put under the care of his youngest daughter and must thwart whatever crazy schemes she concocts to get rid of him.

Characters: A deaged!Endeavor, a not-so-motherly Shiina, the Persona Users, and the people of 1-A.

Pairings: Couldn't decide, so it's a poly between Shiina and some of the male Persona Users

Warnings: Slight, slight NSFW. Mentions of child abuse. Despite the humor, this is kinda angsty and dark... There will also be some spoilers for the original story, but they're very very discreet.

Other(s): This is set post Endeavor vs High End. So basically, Endeavor's finally realized how much of a shitty person he is and is trying to change.

"No."

"Yes."

"No. Please. Anyone but... her."

"Unfortunately, she's the only one that's available." Aizawa said to the pale-faced five year old. It was actually kinda funny to see Endeavor this way. Not only was he literally five, but he looked almost scared too. "Your eldest daughter is away on a field trip with her students, your son, Natsuo, just laughed for a full five minutes before he hung up on us, and Shouto is still out doing his remedial course. Shiina is the only one left available."

Endeavor shook his head desperately, not wanting to believe it. As much as he wanted to have another try at having a relationship with his youngest daughter, this was not how he imagined their first ever father-daughter bonding to go. Plus, he was pretty sure she still resented him. Strongly resented him. To the point where she may or may not plot to kill him.

And since he was stuck in an extremely vulnerable five year old body for a whole day... who knew what she'd do... He shuddered at the possibilities. "Then just drop me off at my home," he tried to reason with the now older-than-him man.

Aizawa simply rose a brow. "Endeavor, you're five. It's illegal to leave children unattended."

"I'm older than you!" He snapped.

"Not right now, you're not. Stop arguing with me about this. It's too late anyways, I've already called her."

Endeavor looked as if his soul had left his body. "You what...?" He said in a terrified whisper.

Creeeeeaaaak.

He snapped his attention towards the door and—if it was possible—paled even more.

She was here.

— ❤ —

Shiina was in the middle of online shopping when she got the call from Aizawa to meet him in the office. She was annoyed, but went there anyway since it was never a good idea to ignore him. But what did he want? Was she in trouble? That was most likely the answer, but what exactly did she do (other than break the law every couple times a day)?

When Shiina stepped into the room, she knew immediately what was going on.

"Aizawa sensei, that's the most hideous child I've ever seen."

"It's your dad," he said bluntly.

"Mm," she nodded. "Yeah I can tell. Can I throw him away?"

"I can still understand you!" The five year old menace snapped.

She scowled. "Ew, it talks."

Aizawa just sighed and pinched the bridge of his nose. "He got attacked by a villain with a de-aging Quirk."

"...And?"

"And I want you to take care of him."

"No."

"Kiberi—"

"—I'm sorry, Aizawa sensei but I refuse to be seen in public lugging around that ugly creature."

The only adult in the room rolled his eyes. "He's only going to be like this for a whole day."

"I can barely stand him for a second." She harrumphed.

"I'll give you a free pass for a whole week. No homework, no tests, all excused." Aizawa offered.

Shiina's eyes glittered and he knew he got her hooked. "You got it sensei! Now gimme the damn brat!"

"Please don't," Endeavor begged as Aizawa turned around and prepared to pick him up. "You can't seriously think I'll be safe in her hands, Aizawa! She's a walking red flag!"

"You Todorokis are always so dramatic," Aizawa sighed heavily as he handed him off to Shiina. "Take care of him, Kiberi."

The smile she wore nearly made Endeavor shit his pants. "Oh don't worry, sensei~" She sang in a saccharine tone. "I'll take good care of him~!"

— ❤ —

When Shiina walked back to the dorm with Endeavor trudging behind her, she immediately attracted the attention of her classmates/dorm mates.

Kaminari's eyes literally popped open upon seeing them. The potato chips in his mouth fell out the second he gaped. "Whoa, Shiina is that your little brother? What's he doing here?"

She gave him a disgusted look. "Ew, no! I'd never be related to something so ugly. And this thing is here because I'm stuck babysitting him as per Aizawa sensei's orders."

Momo stared at them in concern. "Er... Kiberi-san, why would Aizawa sensei put you (of all people) in charge of a child...?"

"I've been wondering the same thing," Endeavor grumbled under his breath. He went unheard.

Shiina simply shrugged. "Beats me. Anyways, I'll see you guys later. Gotta take the brat shopping for new clothes."

"What's wrong with the ones he has on now?" Momo asked.

Shiina just smiled sweetly in return. "They're hideous. So I'm going to get him better ones that I know he'll just love."

Endeavor gulped, having a sinking feeling about this 'shopping trip' of theirs.

After Shiina got her bag from her dorm room, the two of them set off for the children's clothing store. For some odd reason, she decided to look for one in Tokyo rather than Musutafu.

Throughout the walk, he noticed that she didn't even bother to hold his hand—what if he got lost in the crowd or got snatched? But then he remembered that he never bothered to do the same thing with her when she was this age...

"Ah...!" He almost tripped on a broken part of the sidewalk. When he recovered, he almost panicked when he saw Shiina getting farther and farther. He ran towards her and without thinking, reached out to grab her hand for help.

Smack!

He recoiled his hand immediately. Shiina turned around and gave him a dark glare. "Don't ever do that." She hissed under her breath.

He didn't nod or anything because she had already whirled around and walked away. As he chased after her, gripping his stinging hand, he glanced around to see if anyone had noticed what she had done.

Nobody did.

They entered the store in a tense silence. Endeavor watched his youngest daughter as she walked around the store, not bothering to stop or anything. It was as if she already knew what to look for and that made him super nervous.

She went straight for the clothes aisle and after a couple minutes, found whatever she was looking for. She grabbed it from the rack but wrapped it up in a bundle so he wouldn't be able to see what it was. After that, they headed back to the cash register, but she grabbed something along the way too (he couldn't see what it was either).

She set them all on the counter, but he was too short to see over it.

"Will this be all, ma'am?" The lady behind the register said.

Shiina flashed her a dazzling smile that had everyone fooled, and Endeavor found himself sickened by how much she grew up to be like him in a way. He used his hero title to hide his dark side, just like how she used her innocent appearance to hide hers.

Whatever Shiina bought didn't cost a lot, and she immediately took him to the bathroom so he could get changed.

When he saw what she purchased, he nearly passed out from the horror. He hastily backed away until his back hit the wall. He looked around helplessly, the restroom was entirely empty. What bad luck.

"Don't do this...!" He begged. "Please Shiina! I understand that you hate me, but please... Not this!"

Shiina rolled her eyes. "Oh shut up." She said heartlessly before forcing him to wear the All Might onesie.

"I can't go around wearing this!" He protested, huffing as she zipped it all the way up. He stared down at himself and shuddered. He looked like some All Might fanboy... The horror...!

"And why not?" She questioned. "Nobody even knows who you are. Right now all they see is some five year old brat following a girl like some kind of lost puppy! Besides... All Might may not be a hero anymore, but everyone still goes around wearing his merch. He's still widely loved by the public. Even more than you, Number One."

Endeavor looked away from her. Her tone sounded threatening to him.

He had never felt so powerless before, and—as much as he hated to admit it—scared. Shiina held all the cards now. She could hurt him and tell Aizawa he had a simple accident like how he told everyone that Shouto's injuries were due to training. And people would believe her like how they had believed him.

He swallowed thickly at her hurtful words and kept avoiding her eyes which were just as cold as his once were.

"I'm sorry. I..." He trailed off, not knowing what to say. "Thank you for the clothes." He decided on just saying that.

The cold look didn't leave her eyes. "Whatever. I bought you something else too, to keep you from getting lost or some shit. Here." She pulled out something that was much worse than the All Might onesie:

An All Might leash for kids.

His jaw dropped as she tried to put it on him.

"This is demeaning!" He yelled out as she wrestled with him to put the goddamn leash on. "I am not wearing this, Shiina! Stop this nonsense!"

"Put the stupid leash on or else I'll give you up to the first villain I see!" She snapped impatiently. "You know I won't hesitate, you little cretin!"

"I'm not going to walk around with a leash!" He protested. "Why the hell do they even sell these?! There aren't any Endeavor leashes!"

"Someone sounds jealous," she snarked and a second later, the door opened.

A young woman entered and blinked at the scene before. "Oh my."

Shiina put on a sheepish expression. "Er, sorry. Just ignore us."

"Is he giving you any trouble?" The woman asked, and Endeavor was flabbergasted. How could she see him as the troublemaker?!

Shiina sighed dejectedly. "Yeah... I bought this All Might leash just for him because he always gets himself lost in the crowd, but he doesn't want to wear it! I'm only doing this because I care..."

To his horror, the woman sympathized with her and turned to give him a light scolding. "Now little boy, you have to stop giving your big sister a hard time! She's trying her best to watch out for your safety, you know!"

Endeavor continued to gape at her.

She chuckled at his expression. "He's a cute kid," she told Shiina.

"Isn't he?" Shiina chirped, as if she hadn't been calling him 'ugly' and 'hideous' for the past half hour.

The woman chuckled. "Good luck. My four year old can get a little fussy too."

Endeavor was affronted. This lady just compared him to a four year old child!

They left the bathroom once Endeavor had the leash on, and she began dragging him around the city, but not after snapping a couple of embarrassing pictures and sending them to her siblings.

"Where are we going?" He asked after a full hour of walking passed.

"Somewhere," she replied unhelpfully.

He sighed to himself. His legs were aching already and it didn't help that Shiina was tugging on the stupid leash to make him speed up.

She looked at him and arched a brow. "Are you tired?" She asked, sounding concerned.

He nodded hesitantly.

The worried expression on her face faded away immediately.

"How pathetic," she muttered darkly. "You trained Shouto at age four until he was black and blue and spewing out his own vomit, and you can't even handle a little stroll around the city?"

His shoulder shook with frustration. "What do you want from me, Shiina?! Have I not apologized for what I had done? I've paid for my deeds already!"

"No you haven't," she snarled. "You haven't paid shit. You regret what you did? Then drop dead. That's the only form of remorse I'll accept from you."

He stopped walking. "How could you say that?! I'm your father for god's sake—"

"—You were never a father to me," she said lowly.

"I'm trying," he said. "I'm trying to be better, to be a better hero, a better father—"

"—No, you're not, you're just trying to avoid your crimes." She cut in coldly.

His face turned red with rage. "If you'd stop being so damn blind and—!" He cut himself off once he saw the pure hatred in her face. He had said the wrong thing.

"I'm done dealing with your bullshit, Endeavor." He heard her mutter before she dropped the leash and walked away.

His eyes widened. She was leaving behind?! He glared heavily at her back as he tried to chase after. "Shiina, stop!" He ordered, but she didn't listen. "I said STOP!" He shouted, grabbing her hand and yanking her back.

"ARGH!" She suddenly screamed and he immediately retracted his hand upon seeing the small flame in his palm. "You burned me...!" She seethed, glaring darkly at him.

He stood there, horrified. "I—"

"—Are you okay, miss?!" A young man rushed to her aide and winced at her burn. "Here, I have a healing Quirk, let me fix this..." His hand glowed green and hovered above her burn. The ugly red mark disappeared and her skin mended itself.

"Thank you," she said, giving him a charming smile.

"It's no problem. I take it he's new to his Quirk?" He asked, grinning down at Endeavor, not noticing how tense he became.

"Yeah," Shiina giggled. "Thank you so much for healing me. I think he just felt a bit overwhelmed and his Quirk reacted. I should probably take him home now."

He nodded in understanding. "Of course. It was nice meeting you." He walked away, and Endeavor wanted to shout for him to come back.

He was scared.

Because he had accidentally burned Shiina. She was angry with him now and he didn't want to be left alone with her.

She was going to hurt him.

She was going to hurt him like he hurt her.

He looked into her eyes and saw the hatred and the madness... and he found himself being reminded of Dabi, the scarred villain who had attacked him that day. Their eyes were so similar. They were the same color, and they were burning with the same venomous resentment for him.

Their eyes were just like his. Or at least, what his used to be. He didn't think his eyes burned with anger and greed anymore. He liked to think that they were calmer now.

"I'm sorry." He said earnestly.

She didn't say anything. She just continued staring at him with those terrifyingly empty eyes.

He felt a lump form in his throat. "Shiina... I truly am sorry. I did not mean to burn you with my Quirk. It was an acci—"

"—Shut up." She muttered, but her eyes weren't as dark anymore. To him, they just looked miserable. "I can't... just shut up. Please."

He watched her warily. Although her eyes were no longer menacing to look at (did his apology really work?), he was still nervous about what she was going to do in retaliation. One of the few things he knew about his daughter was that she never let a bad act towards her go unpunished.

"I can't take care of you," she finally stated. "So I'm going to do what I should've done a long time ago... and get rid of you."

His blood turned cold.

— ❤ —

She was going to rip her hair out from the frustration of it all. She thought getting rid of her now five year old father would be easy, but she was dead wrong.

She tried tossing him in a dumpster, but he crawled out like the little rat he was and chased after her. She then tried giving him up for adoption but apparently she had 'no legal means' to do that. Her latest attempt consisted of her trying to sell him off for five bucks to some random guy she found in the streets who claimed he liked 'the delicious tender flesh of human children', but the brat went and caused a scene, giving her no choice but to high tail it out of there with him clinging on to her for dear life.

Honestly. Why was the world making it so hard for her to get rid of him?!

"This is the worst day ever," she grumbled under her breath as she stormed through the streets.

"How do you think I feel?!" Endeavor snapped, panting heavily as he tried to catch up to her. The goddamn leash wrapped around his torso was beginning to feel like a dead weight to him.

"I don't care about how you feel." She replied. "You brought this on yourself. What sort of Number One Hero gets turned into a fucking five year old by some irrelevant villain?"

"Language!" He said through gritted teeth.

"Hypocrite." She snarked back. "Ugh, I'm hungry."

"Me too," he said without thinking.

The cruelty in her eyes returned. "Oh you think I'm going to feed you?" She giggled. To anyone else, it sounded sweet and bell-like, but to Endeavor it sounded like the lines of her sanity snapping away. "Do you remember when I was your age? I was malnourished because you kept me locked up. Kept me starved. It took years for me to recover from that. What makes you think I'm going to let the chance to torture you like you did me slip away?"

He felt something drop to his empty stomach. He tried to recall what his daughter looked like as a child, but he could only remember brief glimpses. He knew he kept her locked up, but did she really starve? Surely her siblings would've given her food... Unless they were too scared of getting caught. He was sure Touya at least tried. He was always the most rebellious out of the the five of them.

"You're just... going to let me starve...?"

She bent down so she was at his height and gave him a bright smile. He was pretty sure that outsiders looking into the scene would mistake this as a big sister comforting her scared little brother. It was anything but that.

"Yep!" She exclaimed, cheerfully bopping him on the nose. "And even better: while you starve, you get to watch me eat!"

"Wonderful." He said in an hollow voice.

She straightened up and immediately began dragging him forward. "I'm so glad you agree! Now hurry up, I know the perfect place to go to!"

Endeavor inwardly groaned as he quickened his pace. He didn't know where they were going, and he didn't bother to ask. He started to get a bit concerned when she led him into some shady alleyway though...

Shiina beamed when she saw Akechi inside Leblanc, sipping a coffee and chatting with Akira. They were both alone too. Perfect.

She entered the cafe, dragging the fussy brat with her. "Hey Goro-chan!" She greeted him with her usual bright smile. "Do you know how much the Black Market would sell for a de-aged Endeavor?"

Akechi stared blankly. "What?"

"For the millionth time, stop trying to sell me away!" Endeavor blew up.

"I can cook him for you if you want," Akira casually offered, making the little creature pale because holy shit what was wrong with his daughter's friends?! "Though, I'd probably end up poisoning the customers..."

"Hold on," Akechi spoke up. "What's this about a de-aged Endeavor?" His eyes trailed down to the exhausted child behind her. The upper corners of his lips rose to an amused smirk. "Oh my... Don't tell me..."

Shiina grinned. "Yep. This idiot got himself hit by a villain who turns people into children."

Both boys ended up laughing and Endeavor reddened with embarrassment. They were looking down on him—literally and figuratively!

"Stop laughing at me!" He barked.

Akechi stopped laughing immediately and gave him a dark smile that could rival against Shiina's. "Temper, temper, Endeavor-san. I don't think Akira-kun would like to serve over-emotional brats."

"Then again," Akira chuckled, his glasses glinting somewhat maliciously. "Something tells me you won't be served either way. Is that right, Shiina?"

"Of course not. He needs a taste of his own medicine." Shiina answered all-too-happily as she bounded over to a stool beside Akechi. She didn't bother to help Endeavor climb up his seat. He managed on his own anyways.

"How long will he stay like this anyways?" Akechi asked as Akira began making her curry.

"He'll be back by the end of the day." She replied.

He frowned. "Oh. How unfortunate. So you won't even be able to torture him for that long?"

Endeavor gaped at him. Seriously? Did all of her friends hate him or something?!

A few minutes later, Akira finished with her curry and Endeavor watched enviously as she ate it all up.

She looked at him when his stomach let out a particularly loud growl. She waved a spoon full of curry in front of his face. "You hungry~?" She asked teasingly before putting the spoon in her mouth. He angrily turned away from her.

"You're terrible." He grumbled.

Akira scoffed. "Says you."

"What do you know?!"

"I know enough," Akira glared.

"Endeavor-san," Akechi spoke up. "Would you please keep your mouth shut? Just hearing you talk is ruining my appetite."

Endeavor felt the last of his patience snap. He had enough of this. Of being stuck in this pitiful body, of the hunger, and of their terrible treatment towards him. "Don't you dare speak down on me because of the form I am in! I doubt you wouldn't be so brave when I return to my real age!"

Akechi's charming facade faded away and the look he gave him almost made Endeavor shift back. The look in his eyes was much more maddening than Shiina's... And that was concerning.

Before anything could happen, the tension quickly disappeared as fast as it came when Shiina tenderly placed a hand over Akechi's. "Sorry about him. He's quite mouthy."

Akechi smiled charmingly at her. "That's fine. I'll forgive him... if you give me a kiss."

"What?" Came from the two Todorokis.

Akechi didn't bother to wait. Gingerly cupping the back of her head, he pushed her forward and pressed his lips against hers. It was short and simple, but Endeavor's eyes were nearly popping out of their sockets.

When Shiina pulled away, her cheeks were as red as her hair.

"Your lips are soft as usual, Shiina." Akechi said, and the words echoed in Endeavor's head.

Your lips are soft as usual.

As usual.

They've kissed before?!

Shiina struggled to clear her throat. "U-um, we, uh, should probably get going. I'm done with my food anyways. How much is it, Akira?"

Akira, who had been eyeing Akechi for a while, turned back to her with a devious smirk. "One kiss." He leaned forward over the counter and eyed her hungrily. "This time, you make the first move."

Endeavor finally found his voice, "What are you—?!" Only to lose it again.

Shiina only hesitated for a second before kissing Akira. This kiss was a lot more different than the one with Akechi. While Akechi's was gentle and caring, this one was purely sloppy. Akira grabbed the back of her head, his fingers curled into her hair. Endeavor watched in growing horror as his tongue slipped into Shiina and made a dying noise as she whimpered.

When they pulled away, Akira wore a smug expression while Shiina was left panting and blushing furiously.

"Now what do you say?" He purred.

"T-thank you, Akira." She said in a smaller voice.

Endeavor's jaw hit the floor.

WHAT THE FUCK?!

"W-we should l-leave now. Bye guys!" She squeaked, bringing Endeavor into her arms and leaving the cafe.

Endeavor was at a loss of what to think when he was finally set down.

One, he was pretty sure his daughter just saved him from potentially getting strangled by that shady detective.

Two, what was her relationship with them?! They both kissed her! Right in front of him! The audacity of teenage boys... This was why he couldn't wait for Shiina and Shouto to grow up!

That's not important right now! He mentally screamed at himself.

Was she dating one of them? No, that couldn't be since they both kissed her. Was it a love triangle then? Or... Could it be...?

His eyes widened. Was his daughter involved with the both of them?! At the same time?!

Oh my god, he almost choked at the realization. He was so stunned that he didn't even realize where they were going until she stopped walking. They were in front of a vendor selling taiyaki.

Oh great, he thought grumpily. More food for her to eat in front of me.

Much to his surprise, she shoved a chocolate-filled taiyaki in front of his face as they left the area.

He stared at her, dumbfounded.

"Well?" She huffed. She seemed to have gotten over what Akira and Akechi had done to her since she was no longer blushing, "If you don't want it then I'll take it."

Carefully, he took it from her and asked, "Why?"

She scowled. "I couldn't stand how loud your stomach was growling. It was annoying me. Now shut up and eat it."

He immediately took a bite and felt grateful towards her actions. Perhaps there was still some part of her that cared about him. Even if that part was very, very, very small. To the point where it was almost nonexistent.

His thoughts were cut off by a high pitched squeak. He shot his head up only to see some hooligan wrap his arm around Shiina from behind while the other had a hand firmly squeezing on her bum. His head was angled downwards, face pressed against her neck and he could hear the loud smooches the young man was making against her skin.

Not another one...! He thought dreadfully.

"Urgh, Ryuji, not now!" Shiina complained, prying herself away from his grabby hands.

Ryuji... Endeavor mulled over the name before realization smacked him across the face. SAKAMOTO?!

"Aw come on, babe, the hickies I left on you last night are all gone now! Unless you covered them with makeup. Totally not fair." The blonde scowled at her flawless neck as if it had offended him.

"SAKAMOTO!" Endeavor roared in his squeaky, five year old voice. "STAY AWAY FROM MY DAUGHTER!"

Ryuji merely blinked at him. "What the hell? Shiina, who is this brat?" His eyes suddenly widened as a knowing grin lit up his face. "Oh no way! Is this Endeavor?! Hahaha! Why's he so tiny?!"

"He was hit by a villain's de-aging Quirk," Shiina explained tiredly.

"You ever thought of putting him up for adoption?" He suggested eagerly.

"HEY!"

"Unfortunately, I don't have the legal rights to do it," she rolled her eyes in annoyance. "Stupid laws."

"What about just... throwin' him away?"

"Tried it."

Endeavor was seething. "HEY!" He barked at the blonde. "Stop ignoring me, Sakamoto—"

"—How about Akechi and the Black Market?"

"Just tried that too." She said.

The five year old balled his tiny fists. Just when he was a second away from having the temper tantrum of the century, a newcomer arrived.

"Shiina," a masculine and lovestruck voice breathed out. Endeavor let out a long groan as another male arrived. He was tall with dark blue hair and—

Wait haven't I seen him on the news before? Something about Madarame?

"Oh Yusuke!" Shiina said the stranger's name happily. "How've you been?"

"I've been pining for you," he shamelessly admitted. "When will you visit me so I can draw the most perfect painting of your nude body?"

"What?" Endeavor squeaked incredulously. "Nude—?! No! No, there won't be any nude paintings!"

Yusuke blinked down on him. "Who is this small... creature?"

"It's called a 'kid' Yusuke," Ryuji snorted.

"It's Endeavor," Shiina clarified. "He was struck by a villain's de-aging Quirk, so he's five now but he retained his normal memories."

Yusuke smiled in amusement. "Turned into a five year old? Quite befitting for his personality."

Endeavor was about to burst, "You—"

"—Sorry to cut this short guys, but I'm really tired from dragging this kid around. I think I'm gonna rest up at Aki's place since it's nearby." Shiina said.

Ryuji frowned in disappointment but nodded in acceptance. "Oh fine. But you're coming over again tonight right?"

Please say 'no'.

"Definitely."

"Ahem," Yusuke said pointedly.

Shiina turned to him and gave him a teasing look. "Don't worry Yusuke, I haven't forgotten about you. I'll meet up at your place on Saturday so I can stay over Sunday."

"You need Aizawa's permission for that!" The child snapped.

All three teens burst out laughing.

"He really doesn't know, does he?" Ryuji chortled.

"Know? Know about what?!"

"Why would he know anything?" Shiina snickered.

"Answer me!" He demanded, but was ignored.

"I gotta get going, so I'll see you guys later." She said to them.

Yusuke nodded in understanding and softly pressed his lips against her forehead.

A kiss on the forehead. Okay, that was fine. That was something he could approve of.

But then:

Ryuji scoffed, "Come on, Yusuke, you can do better than that."

Yusuke smiled suavely. "If you insist."

Smooth as ever, the young man wrapped an arm around her waist and pulled her forward before locking their lips together in a passionate kiss. Endeavor felt like gagging and screaming at the same time. He was left thoroughly sickened by the time they (finally) pulled away, both breathless.

"I'll be going now! Bye guys!"

"See ya, babe!"

"Goodbye, Shiina."

The two boys were finally gone now, leaving him and Shiina to walk to wherever this 'Aki' lived. He wondered if this person was a boy or girl. He hoped it was a girl, but the world wasn't exactly being kind to him at the moment.

In fact, the world was being downright cruel to him.

'Aki', whose name was actually Akihiko, turned out to not only be a boy. But a man. An older man. Probably older than Natsuo even.

He watched in agonized silence as they shared a kiss just as they stepped into his apartment.

That was when he finally caught sight of him.

Akihiko looked at her. And then the child. And then back at her.

His jaw went slack. "Y-you reproduced?! Since when were you even pregnant?! God that better not be Minazuki Sho's kid!"

Shiina angrily whipped off her sunglasses. "Excuse me?! How dare you accuse me of giving birth to something so uncute! Besides he's five! And I'm fifteen! Are you seriously telling me you thought I got pregnant at age ten?!"

"Well... yes?"

SMACK!

Endeavor almost facepalmed. Why did her lovers have to be so stupid?

"I'm sorry, but can you blame me?" Akihiko crazily motioned to him. "He's the spitting image of you two! He's got your guys' hair and eyes... Not to mention that really angry expression on his face just screams 'Minazuki Sho's offspring'."

He briefly wondered who 'Minazuki Sho' was and prayed it wasn't another lover.

She pinched the bridge of her nose. "That's Endeavor."

"What."

"He got hit by a villain's de-aging Quirk." She was getting really tired of saying that all the damn time. "So now the bastard's five, but his mind hasn't changed."

Akihiko bit his lip as he scrutinized the child, "I hate to say this but, he's actually kind of adorable."

Their jaws dropped.

"He is NOT adorable!"

"DO NOT CALL ME THAT!" They screeched.

Akihiko chuckled and raised his arms up in defense. "You guys are too alike."

"WE ARE NOT!" They protested.

"So how long's he stuck like this?" Akihiko asked, completely ignoring their annoyance with him.

"He'll be back to normal sometime tonight," she answered.

"That's good," Akihiko said, and Endeavor silently agreed. "But... why are you taking care of him?"

"What's wrong with a daughter taking care of her ill dad?" She said sweetly.

"I'm not ill!" Endeavor snapped.

"You're a little red in the face..." Akihiko pointed out.

"That's because I'm angry!" He seethed. "I've been belittled this entire day!"

"Wrong word choice there, buddy." Akihiko snorted, bending down to ruffle the little guy's hair. He chuckled when his hand was swatted away.

"DON'T TOUCH MY HAIR!"

"He's just like you," Akihiko sighed fondly at Shiina, who huffed.

Just then, the door swung open and a brown haired boy (someone around Shiina's age) stepped in. He looked around before spotting them and sighing in relief.

"Oh good, you're here," he said. "I almost had a heart attack when Kaminari said he saw you with a child... Especially when he said it looked a lot like you..."

Shiina scoffed. "Lemme guess, you thought I had a kid with Sho-kun didn't you?"

"Not really, I thought you were trying to hide a secret Todoroki sibling," he admitted. His brown eyes transferred over to Endeavor and he walked over to him with a friendly smile. "Hi there," he greeted. "I'm Amada Ken."

"Endeavor." He replied gruffly.

Ken blinked. "He's joking right?"

"De-aging Quirk," Shiina stated dismissively before giving him a bright smile. "But forget about that! I missed you, Kenny~!" She sang before glomping him. Without hesitation, she smacked her lips against his while Akihiko watched on in amusement.

Ken turned beet red at the affection. "S-Shiina not in front of your dad!"

"Oh who cares, Kenny~" She giggled mischievously. "It's not like he can do anything about it."

"B-but still!" Ken said, trying to push her off but his movements were weak as if he didn't really want her to let go. "It's inappropriate!"

She scoffed loudly. "Inappropriate? After what you did to me a few days ago, you're worried about being 'inappropriate'?"

Ken stammered, but couldn't say anything coherent.

Endeavor's face fell to an expressionless one. "Shiina." He said in a stiff voice. "You better not have gone far with any of these boys."

"Gone far?" She echoed, wearing a shit-eating grin. "Oh I think we went beyond that when they all decided to gangbang me that one day. You guys remember that?"

Akihiko went speechless while Ken honestly looked like he was going to faint.

Endeavor felt the same way. "You... No... You didn't." He croaked. She couldn't have. She was just lying to piss him off, that was it! There was no way his fifteen year old daughter actually allowed herself to be debauched by six (or were there more?) men at once. No, no, no, no, no—!

"Oh we did," she said delightfully. "I even have the pictures and videos on my phone. In fact, we all do. It was Akira's idea, that little horndog." She giggled watching as he swayed on the spot.

Akihiko began eyeing. "Kid, you okay—"

"—It was on your bed too," Shiina continued to taunt.

No. No, no, no no—

"After you were hospitalized from that Noumu attack Akechi had the brilliant idea of us doing it in your bedroom. The whole house was empty so it was perfect. I can't believe you didn't even notice all the stains—"

Thump.

Shiina peered down at Endeavor's fallen body and smiled. "Finally." She said.

"You're evil." Akihiko and Ken deadpanned.

— ❤ —

When Endeavor opened his eyes, he was met with the faces of his children, except for Shiina. Only Fuyumi looked worried.

"How are you feeling dad?" She asked.

"I... I feel fine," he replied, his voice slightly hoarse. "What's going on? I remember getting hit by that bastard's Quirk, and then Shiina had to take care of me and—" He quickly sucked in a breath at the mention of his youngest child. His whole body stiffened as if on high alert. "Shiina. Where's Shiina? Is she here? Is she alright?"

"Calm down, she's just fine," Natsuo rolled his eyes. "She's with one of her classmates—Amada, I think?"

Endeavor's eyes bulged. "HIM?! NO! That's unacceptable! You have to keep those two separated!"

"What? Why? What's wrong?!" Fuyumi asked hurriedly as she tried to push him back down on the bed. "Dad, stop, you're still a bit exhausted after turning back to normal!"

He looked back down at his palms, which were no longer small and baby-soft. He was back to his original age....

Perfect. He could finally kill those boys.

"Where are they right now?" He asked, glaring at them. "Tell me where Shiina is, she's not safe with that boy!"

"A-Amada-kun?" She gave him a bewildered expression. "Why ever not?"

"Because he's corrupted her! They all have!" He roared. "Before I passed out—She—she told me that they... they had sex with her! All six of them! Him, Sanada Akihiko, that goddamn Akira kid, that creepy detective prince, Akechi Goro, the Sakamoto boy, and that artist guy, Yusuke! She told me herself that they've corrupted her!"

Shouto gave him a dry look. "Right, old man."

"I'm serious!" He snapped.

Shouto's expression didn't change. "Shiina would've told me if she was dating anyone."

Natsuo nodded in agreement, "Yeah she would've told all of us so we could see if they were good enough for her!"

"She's not dating one person, she's dating six and they're deflowering her!" Endeavor hissed.

Fuyumi looked at him warily. "Dad... are you okay? I mean, I've met Kitagawa-kun before and he's nothing but a gentleman! And Amada-kun seems like a good boy too. I highly doubt either of them would... do that to Shiina. Plus, Akechi Goro is a famous detective, how would they even know each other?"

Endeavor's jaw dropped. "You don't believe me?!"

"Nope." Natsuo answered.

His glare turned fiercer. "I'm telling the truth! Shiina and I went to this man—Sanada Akihiko's—apartment and for some reason, that Amada boy knew the way there too! She kissed them both—the others too after she dragged me all over Tokyo—and told me that they've been fucking! They—they even have pictures and videos on their cellphones! Check it right now if you don't believe me!"

"I'm not gonna go snooping through my little sister's phone, are you crazy?" Natsuo sneered. "I actually value her privacy."

"Besides," Shouto spoke up, completely unamused by his tirade. "You never went to Sanada's apartment nor did you meet with any of those boys. You didn't even leave Musutafu. According to Shiina, after she was kind enough to shop for your clothes and fed you, she took you to the park so you could play with children your age. You refused and had a temper tantrum that went on for hours. Then you passed out. The doctor even confirmed it: you fainted from being overly emotional."

Natsuo scoffed angrily. "Figures you tried to pin all this on Shiina. You even tried to make her sound like some sort of deviant! The hell's wrong with you?!"

"I'm disappointed, dad," Fuyumi said sadly. "You said you'd try to be better..."

"I-I am," he spluttered, bewildered at how everything was turning against him so easily. "It's Shiina who isn't! She's acting out, and being all rebellious and these boys—"

"—Again with this?" Shouto glared icily at him. "Shiina wouldn't do something so vile. I would've found out and put a stop to it."

"Well you failed—!"

"—Just stop, both of you!" Fuyumi shouted. Shouto quieted down immediately. Her grey eyes turned to Endeavor and she could see the disappointment in them. "I know your relationship with Shiina is strained, but these accusations you're making are completely childish!"

Endeavor opened his mouth to argue, but she raised a hand to stop him. "I want you to apologize to her after this. You caused her a lot of trouble, you know? She was being so kind to take care of you... She even bought you clothes and food and took you to park so you could play and this is how you treat her?"

He was spluttering. "She was not being kind to me, she was being an evil little—"

"—Dad!" She hissed, eyes widening at the figure under the doorway.

He turned and saw Shiina. But that wasn't all. She was... crying?!

"Evil?" She repeated in a small voice. "I only wanted to make you happy since I knew how much you hated your situation...!" She choked on a sob.

"Imouto..." Shouto said softly, his brows furrowed with worry.

"Aw don't cry, imouto-chan!" Natsuo was quick to envelope her in a hug. "Forget what he said. He's just an evil bastard."

"It's not your fault," Fuyumi said soothingly as she handed her a box of tissues. Shouto quietly joined in, cooing words of comfort to her as she cried in Natsuo's shoulder.

Endeavor felt an ache in his chest. Perhaps... perhaps his kids were right. Maybe none of that really did happen and maybe he just dreamed it all up.

He heard another quiet cry from her and grimaced. He truly felt bad for making her cry. He opened his mouth to give her a small apology until she lifted her head from Natsuo's shoulder and locked eyes with him.

She flashed him a wicked smile.
