__________________________________________________________________________________

[3rd Person POV]

"Yes, I am older than (Y/n). And you may know me by another name. In school, I was referred to as...Lady Nagant. But more importantly, those closest to me, and (Y/n), would simply refer to me as...(Y/n)'s girlfriend."

Those final two words left both Rumi and Kayama in a frozen state, even as they sat on the stone bench alongside (Y/n), the two girls didn't know what to do. This girl, no...This woman...She was definitely pretty enough to be called a woman. Calling her a girl would definitely undermine that...Claimed to be (Y/n)'s girlfriend. 

But (Y/n) had never mentioned her once. Another twist that caused the girls to grow confused. There was so much going through their heads that they didn't know what to say. In the end, they were suddenly brought back to reality as (Y/n) got to his feet and slightly approached Kaina. His chuckle broke the mould.

(Y/n): "Um...You're not my girlfriend."

Rumi: "What?!"

Kayama: "What?!"

That one statement instantly knocking the girls back into reality. Their dumbfounded looks remained as (Y/n) nervously rubbed the back of his head.

(Y/n): "You guys are gonna have to forgive Kaina. She tends to uh...tease me."

Kaina: "Tease you?"

She sends a blank expression toward the boy.

Kaina: "If I am not mistaken, almost everyone said when we were younger that we looked like we were dating."

(Y/n): [Mumbles] "And how many times do I have to tell you, just because people say that, it doesn't mean we're actually dating."

Kaina: "...But you saw me naked."

Kayama/Rumi: "WHAT?!"

(Y/n): [Turns to Kaina] "I DID NOT SEE YOU NAKED IN THAT WAY AND YOU KNOW IT!"

The words of (Y/n) merely echoed further and further as he explained to Kaina, and most importantly, Rumi and Kayama, that the situation Kaina was talking about relayed to a time when they were both seven years old, and Kaina had come over to (Y/n)'s house to swim in the pool with him. One thing led to another, with (Y/n)'s mother refusing to remind the young boy that Kaina was getting changed in the outdoor bath house. 

Of course, that's where (Y/n) also went to change. But when he opened the door he was greeted by quite the surprise. It was nothing more than an accident. But Kaina seemed to have a tendency of bringing such a memory up whenever in the presence of (Y/n)...and girls were around him. As the explaining came to an end, (Y/n) pulled Kaina to the side to ask her exactly what she was doing here. 

This left Rumi and Kayama to their thoughts. Whilst they were happy this girl wasn't (Y/n)'s girlfriend. The fact she knew (Y/n), and clearly, for a long time, left them feeling uncomfortable in their advance to confess to the young boy. These thoughts continued to plague their minds until (Y/n)'s voice sounded them back to reality.

(Y/n): "Um...If you guys wanna wait here, me and the guys can go get the stuff and we can get back before the bus leaves. We'll, um...We'll be back."

Without another word (Y/n) turned and left, the boys following after. A bewildered expression could be seen resting on his face as he did so. Both Kayama and Rumi noticed such, leaving them continuing to question everything going on. Their eyes continued to follow after before suddenly their gaze was sent back to the newest arrival. Kaina's emotionless gaze was already set on the pair that sat before her.

Kaina: "So you two like (Y/n)?"

Kayama: "What?"

Rumi: "Hmmph! ...So what if we do?"

Kayama's statement was filled with confusion, the cause from her mind suddenly shifting to someone else. As for Rumi, her's contained the usual tough attitude. She was giving this Kaina girl an inch. But what surprised Rumi, Kaina didn't cave to fear. Instead, she remained emotionless. Her purple hair blowing in the wind as she eyed the girls before her.

Kaina: "That's perfectly fine if you do...But it is a waste."

Kayama: "Excuse me?"

Kaina: "I understand you both think you're pretty, but trust me, I know what (Y/n) is into. Me and him have been friends since we were five years old, after all."

Rumi: "What's that got to do with it?"

Kaina: "...It has everything. It means I have an advantage in this little game."

Game...? Wait, she didn't mean--

Kayama: "You like (Y/n) too?"

Kaina: "Of course I do. He's the perfect boy. I mean, clearly, it was enough to entrap you two."

Kayama: [Blushes] "I-I wouldn't exactly call it that..."

Rumi: [Crosses arms] "Please. I was not entrapped by anything. If I was...I would merely break it and free myself."

Kaina: "You both say that, yet here you are, coming to a beach dressed in quite revealing clothing all to please this one boy. I don't know what you think that is, but to me, it's rather obvious."

Who were they kidding? It was obvious. And it wasn't like they didn't like (Y/n). They did.

Kaina: "Unfortunately for you both, your attempts at 'wooing' him, are futile. It is destined that he and I start dating. Well, officially anyway. I've always seen us as a rather nice couple."

That was the final statement Kaina gave, a slight grin spreading across her lips before she turned and walked away. All the while Kayama and Rumi were left in shock. Before today, they thought their greatest problem was each other. But now they came to understand something...There was always a bigger fish.

******

As the weekend passed, both Kayama and Rumi were left to ponder what had happened at the beach. The idea of one of them ending up with (Y/n) had now become clouded, all due to the sudden arrival of Kaina. What made them even more worried, however, was the reputation Kaina, also known as Lady Nagant, had whilst in U.A. And it definitely wasn't good. All of this brought together made Kayama really sad.

All she wanted was to date the boy that somehow managed to make her feel so happy. Yet one after the other, all these hurdles appeared before her. However, a big surprise was in order within the next few seconds, as Kayama, dressed in her school uniform, could be seen walking to her next class. Her head was buried to the ground as so many thoughts plundered her mind. That was until out of nowhere a hand came to whack her over the back of the head.

SLAP!

Kayama: "OW!"

The only reaction she could make. An agitated look spawned on her face quickly as she turned her head to see Rumi was the cause. Even more of a surprise, she walked by Kayama's side as if she had been doing so for the whole morning. No reaction on her face as the purple-haired beauty glared at her.

Rumi: "Do not release such a pathetic sound, girly. We are at war."

Kayama: "What the hell, idiot? What did you do that fo--Wait...What do you mean war?"

Rumi sighs, it seems to physically pain her as she grasps her forehead and shakes her head. All before she turns to Kayama.

Rumi: "This is what makeup does to your brain. You should just accept it that you do not have natural beauty like me." [Sighs again] "I am talking about the war of love that we are in the midst of."

Kayama: [Mumbles] "I really have fallen down the social ladde--"

SLAP!

Another slap sounded, courtesy of Rumi.

Kayama: "Would you fucking stop that?!"

Rumi: "How can I when you are droning on about useless stuff? We have much bigger problems. Namely Lady Nagant."

Kayama: "Lady Nagant? What are you...Oh..."

Rumi: "I have done all the research I could over the weekend about our target. She has quite the resume for destruction." [Chuckles] "Honestly, a lot of this stuff is hilarious."

Kayama: "What are you talking about?"

She groaned with annoyance on her breath.

Rumi: "During her time at this school, Lady Nagant demanded quite the presence. She was cold to her peers. She would not take jokes from anyone. And she'd beat the ever-living shit out of people she fought against in battle. Speaking wholeheartedly, if she was not trying to steal my man from me, I would be rather impressed to be in her presence. But that is neither here nor there!" [Turns To Kayama] "It is clear that she is trying to take (Y/n) from us, so we must act quickly."

Kayama: "Quickly? Act?" [Groans] "Seriously. If you don't start talking some sense I will bitch slap you to whatever burrow you crawled out from."

Rumi: [Sighs] "Why am I not surprised you do not understand such simplisities." [To Kayama] "I am saying we must form an unlikely alliance if we wish to keep (Y/n) from the clutches and be defiled by this woman."

Kayama: "...This woman? You mean Kaina. She's just a girl I don't think--"

Rumi: "No. The first thing of war is we must show respect to our enemy. And this enemy is definitely no 'girl'. She is a woman...Like me." [Sighs] "But in saying that, I, despite my brilliance, have realized it would be futile going up against her alone. That's why I suggest we work together."

It was safe to say Kayama couldn't believe what she was hearing. Then again, that could be said for her whole life at the moment.

Kayama: "Why would we work together? You hate me...Heck! I hate you."

Rumi: "Yes, I understand we have our differences. But when you look at the facts. This is the way to go. By working together we will have a much better chance at beating Lady Nagant. For alone we will not stand a chance against her proxy. She is but a beautiful woman with bountiful breasts and thighs that be saving the lives...(Y/n)'s small human brain will not stand a chance."

Kayama: "...So we work together, and what?"

Rumi: "And do everything we can to show that we are better than Lady Nagant. Once she is out of the picture, we will be able to once again compete for (Y/n). After all, would you not rather we go against each other instead of that...Bombshell?"

As the seconds built up, Kayama found herself thinking over the situation. She couldn't believe she was. But she was. And as she did, so had to admit...Kaina was quite the beauty. Something Kayama had to admit. Though, in the popular girl aspect, had to admit her pretty look was just sleazy. She would definitely be hard to defuse when (Y/n) was around. So having a helping hand from Rumi would definitely help. And even so, if all else fails, Kayama could just through Rumi under the bus.

As for the future rabbit hero, she, too, was against working with Kayama at first. But after her weekend of studying, she realized Lady Nagant was quite the violent person when it came to things she wanted. And Rumi did not like the way she looked at (Y/n) at the beach. She would make sure once (Y/n) and Rumi were dating, she would discipline the boy into not looking so good to the eyes of other girls. There was the pain of working with Kayama, however. And even so, if all else fails, Rumi could just through Kayama under the bus.

Rumi/Kayama: "Fuck it. Let's do this!"

With that the girls spawned a pair of confident grins as a plan began to form in their minds. It wasn't much yet, but as it continued to grow, they knew it'd be enough to make (Y/n) see them in a way better light than he did Kaina. So from that moment on the pair of Rumi and Kayama worked together to defuse this situation as fast as they could. However, as the day continued, they would come to understand that Kaina would be a much more present force than they first expected.

"Alright, class, I would like to introduce you all to Lady Nagant. She is a professional hero who graduated from U.A. just last year. She will be assisting us the next few weeks in order for you all to be ready for your final assessment to becoming full heroes yourselves. when you verse students from other schools." [Turns to Kaina] "Would you like to say any words?"

Kaina: "Whilst I only graduated last year, I want you all to know...I am a thousand times better than you all."

"Oh, um...Alri--"

Kaina: "Also...I am (Y/n)'s girlfriend."

"WHAT?!"

"NO, YOU'RE NOT!"

The voice of (Y/n) echoed in the back of the classroom as Kaina just stared blankly.

Kaina: "...But you saw me na--"

"WE DON'T NEED TO HEAR ANY MORE, KAINA!"

Enji: "Oh, yes we do! Ha! Ha! KEEP GOING!"

(Y/n): "Shut up, Enji!"

Enji: "NEVER!"

Toshinori: "Ha! Ha! You're so funny, Enji!"

Toshinori giggles gleefully before wrapping his arms around Enji's in a hug. The mess that follows spews into the background. In the end, this whole mess caused everyone to look around in confusion and wonderment at what was going on. But for Kayama and Rumi, their narrowed gazes remained toward the front of the class where Kaina stood.

Kayama: "She's going to be working at the school? We can't catch a break."

Rumi: "Of course she is...She's using it to get close to (Y/n)."

Kayama: "Okay. I don't think it's for that--"

--30 Minutes Later--

Kayama: "...Okay, maybe it is."

Kayama said with a blank face as she looked in the distance, currently standing in the school's gym, she saw (Y/n) seated on the ground. All the while his back was being slowly inched forward, his stomach slowly approaching the ground. He was, of course, currently being stretched by Kaina. Who just had to have her big boobs pressed against his back as he did so.

Kaina: "Just let me know when it hurts (Y/n)."

(Y/n) In Physical Pain: "It hurts...It hurts...KAINA! IT HURTS!"

Kaina: "...Good. That means it's working...Let's keep going."

(Y/n): "No! Don--"

CRACK!

The sound of (Y/n) screaming in pain follows seconds later. As this happens, Kayama winces in pain. Whilst Rumi merely narrows her gaze.

Rumi: "Look at her. Has she no shame? The way she pushes her chest up against (Y/n)'s back is so displeasing..." [Turns to Kayama] "Kinda like you."

Kayama: "Do you want my help or not?!"

Rumi: "Yes. Yes. Calm down..." [Mumbles] "Of course, you are sensitive."

Kayama: "What was that?"

Rumi: "Nothing! But more importantly, you must focus. Lady Nagant has already gotten the first step in seducing my (Y/n)."

Kayama: "Excuse me? Your (Y/n)?"

Rumi: "Details! Details! The point is...She is pressing her boobs against (Y/n). If we do not hurry, his mushy boy brain will succumb to her seductions."

Kayama: "Alright. So we have to hurry. What do you have in mind?"

Rumi: [Smirks] "Don't worry. For this, I have the perfect idea. It's something you're good at."

Kayama: "And that is...?"

Rumi: "Stealing someone else's man, of course!"

As soon as Kayama heard such words her eyes almost snapped out. A fierce glare was sent in the direction of Rumi, who, of course, just looked at Kayama in confusion. A few minutes passed as the pair sought out their differences. As this happened, (Y/n) was finally given rest from his prison as Kaina helped him to his feet. A gentle smile running across her lips.

Kaina: "There we are. All done, (Y/n)."

(Y/n): [Fake Chuckles] "Gee...Thanks, Kaina."

Kaina: "That's alright. Though, I must admit, even after three years of being at U.A. You're still the same (Y/n) I knew when we were kids."

(Y/n): "How so?"

Kaina: "You still can't handle your stretches properly. Ha!"

(Y/n): "Pfft! Please! That's not stretching. What you do is painful torture." [Smirks] "Besides, you know me. I much rather the action over--"

"Oh, (Y/n)~"

As the words sounded, both (Y/n) and Kaina quickly turned in the direction they came from. As they did, they were greeted by the sight of Kayama strolling their way. But this time there seemed to be something different about her. Sparkles seemed to surround Kayama's person. Her unrivaled smile on full display as she flung some hair over her shoulder. The sight alone caught (Y/n) in a daze. Before he knew it, Kayama reached him. What surprised him further, however, was how she outright pushed her body against his, and moved her face until it was inches from his own.

Kayama: [Pouts] "...(Y/n)..."

(Y/n): "Um...H-Hey, Kayama. What's up?"

Kayama: "I can't do my stretches properly...Can you help me?"

(Y/n): "H-Help you? Help you...How?"

The final word came with a loud gulp. As soon as Kayama heard such, she smirked to herself. Long gone were the days that (Y/n) could no longer resist her charms. And the more her gaze continued to lingered, the more (Y/n) found his thoughts disipating. And when she giggled in that cute way (Y/n) had always noticed, he was almost at his breaking point. Though, just as anything more was about to happen, the pair were cut off as Kaina intervened. Stepping between the pair, Kayama to be pushed back ever so slightly.

Kaina: "Please tell me how you struggled with simple stretches?"

Kayama: "Huh? Oh...Uh...I forget!" [Giggles] "But (Y/n) seems to have a good idea of how to...Stretch me out~"

(Y/n): [Blushes] "E-Excuse me?"

Kayama just giggled once more as Kaina's eyes narrowed in on the girl. Then, out of nowhere, Rumi appeared behind (Y/n). Her arms wrapped around the boy from behind. This time, her own breasts pushed against his back. Startling the boy to life. Even more when she started rubbing her cheek against his own as she smiled.

Rumi: "Yo, (Y/n)! Help stretch me too!"

(Y/n): "Rumi! You too?!"

Rumi: "Of course. Whilst I don't need help, like Kayima does--"

Kayama: [Mumbles] "It's fucking Kayama."

Rumi: "--I simply wish to have you in my presence..." [Turns to Kaina] "Oh, hello, Lady Nagant. I did not see you there. Bully any small children as of late?"

Instantly the trio of (Y/n), Rumi, and Kayama proceeded to turn to Kaina, who seemed anything but impressed.

Kaina: "No. But I am rather disappointed in what I see right now...You both are distracting (Y/n) from his vigorous training!"

As soon as the words came from Kaina's mouth, any plan Rumi and Kayama had were instantly scrapped.

Rumi: "What?!"

Kayama: "We're distracting him?! You're the one that had him stretching long after everyone else was finished!"

Kaina: "I did that for his own good."

Kayama: "Right, his own good."

Rumi: "Admit it! You simply wanted (Y/n) to yourself!"

(Y/n): [Chuckles] "Okay, guys, I think we're being a bit rediculous here. I think we just--"

Kaina: "You're right."

(Y/n): "...Excuse me?"

Kaina: "You're right. I do want (Y/n) to myself. After all, I have known him since we were kids. He has seen me naked--"

(Y/n): [Mumbles] "Do you really have to keep bringing that up?"

Kaina: "And most importantly...Over my years of being at this school, I know exactly what the girls here are like."

Kayama: "And what's that suppose to mean?"

Kaina: "...(Y/n), go get ready for your first match."

(Y/n): "What? But I want to--"

All it took was for Kaina to turn a simple glance in the direction of the male. Seconds later, he could be seen walking off to get ready for his first match of the class. Though, (Y/n) was hesitant to leave, he did so, though for a reason. As for the others, both Rumi and Kayama stood before Kaina with their arms crossed as they waited for her to continue.

Kayama: "So? What were you going to say?"

Rumi: "Yes, tell us. Before I punch you."

Kaina: "...Do you both know why I told (Y/n) to leave before I said anything?"

Kayama: "Pfft! Probably so you don't seem like the bad guy. Girls like you are always--"

Kaina: "It's because I know what (Y/n) has gone through in his life."

Kayama: "Excuse me?"

The stern look in Kaina's eyes proceeded to soften as thoughts plundered her mind. It left both Rumi and Kayama confused. But that confusion would take a quick turn when Kaina spoke out once more.

Kaina: "Ever since I knew (Y/n) as a kid, he was always nice. Unlike a lot of other people...He had a soft heart. He always found friends with people around him. He was never cruel. Never mean. And always had a smile. He found having a smile was the best  thing to have...Even in the darkest moments."

Instantly Rumi's mind was sent back to the first time she fell in love with (Y/n). The day in the library, when he told her how important a smile was.

Kaina: "Long story short. (Y/n) was always an easy going guy, not much for emotions, and sometimes dense. But that changed when he met a girl in our junior school. He liked her. And she made him smile. But there was a day when she made him drop that smile. Because where as (Y/n) loved her so much, she liked someone else. And that hurt (Y/n)..."

Kayama's mind switched to the present. (Y/n) felt the same pain she felt when she saw him with Rumi. Little did Kayama know, (Y/n)'s was much worse.

Kaina: "But (Y/n) still supported his friend. The girl he liked. Even as he watched her and this other guy get other, right before his very eyes. He still smiled...He smiled because he believed it'd make his friend happy. And it did. But (Y/n) couldn't smile any more when he saw his friend's boyfriend cheat on her behind her back. Now, most people would have gone to tell the girl. But not (Y/n)...He was so mad at seeing his friend hurt, even when she hurt him, that he outright punched the guy. A wave of steam came with that punch and left a scar on the guys face."

Kayama: "No way..."

Rumi: "(Y/n) did that? He wouldn't seem like the person to do something so awesome like that. He's far too much of a good guy."

Kaina: "Yeah, well, he did. He did it because he still cared for his friend...Even though she didn't care for him. But in the end, that friend paid his kindness for turmoil. Apparently the boyfriend of the friend raced off and told the teachers, who blamed (Y/n) for everything and he got in trouble. A few days later, (Y/n) was confronted by his friend. She screamed and hit (Y/n) because her boyfriend dumped her because (Y/n) was 'crazy'. She blamed (Y/n)...When all he did was protect her."

Kayama: "But why didn't (Y/n) tell her that? Surely she would listen? Even the teachers?"

Kaina: "He tried. But no one listened to him. Such a sweat, caring boy was left broken. An outcast by all except for me. For two years (Y/n) lost his smile...But when he got it back, I...I swore to myself that he wouldn't get hurt again!" [Sighs] "...I lied when I said I liked (Y/n). At least, in that way. But don't think for a second that I'm just going to let the two of you give him hope only to tear it away again. I've seen what the both of you are like at this school."

Kayama: "Hey! You can't judge us! You don't even know us!"

Kayama tried to defend, but Kaina was quick to bite back.

Kaina: "Is that so? Kayama, the most popular girl in her grade. You could have all the guys possible, and every time a guy gives you attention. You get with them to play with their hearts. You simply like the attention they give you whenever you flirt with them."

Kayama wanted to defend herself again. However, she shut herself down when she remembered her first interaction with (Y/n). The only reason she went off with (Y/n) in the mall was to see him flustered from her, to give her attention. She didn't do it because she liked him...That came after.

Kaina: "And you, Rumi. You don't have many friends, if any, at this school. You rather bark at people whenever they try to get close. You don't care for peoples feelings. You just push them down so you can get a higher view point in your life. I wouldn't be surprised if you already tried something like that with (Y/n)?"

Rumi wanted to fight. To argue. But she just couldn't! She remembered his enraged she was when she first met (Y/n). The way he fought against her made her angry. So much so she tricked him into studying so she could make him look like a loser. How pathetic was that? It was as the two girls thought over this that Kaina spoke out once more.

Kaina: "...So you both see, (Y/n) is a sweet guy. Who cherishes a smile. And I don't want to see him lose his ever again."

Kayama: "Look...I know we might have been in the bad at the start. But seriously, I really do like (Y/n)! He's sweet, and kind. And he thinks I'm pretty for me...And not because of stupid makeup."

Her head dropped in embarrassment at the last part. Even so, it was one of her greatest memories with the boy.

Rumi: "And whilst I may have started out with the intention of ridiculing (Y/n), I, too, have changed. (Y/n) is the only person I know who matches me in fitness, fighting, and..." [Blushes] "He makes me laugh...And I like that."

A split second the girls' eyes filled with hope as Kaina stared at them. They hoped their words would change something. But all Kaina did was shake her head.

Kaina: "...Even so. I still don't trust either of you to properly look after (Y/n)."

Kayama: "But we can!"

Rumi: "How can we prove it?"

Kaina: "Well, that's simple. The one way I can be shown that you're both serious about loving (Y/n)...Is by beating me in a fight. But trust me when I say...That won't be no easy task to do."

As the terms were laid out, both Rumi and Kayama were left to ponder such a matter. It was as they did so that a voice called from behind.

"And here we are with the first match up of the day! Enji Todokori VS. (Y/n) (L/n)! Let the match...Begin!"

As the words sounded the trio of girls turned around and witnessed the snarky grin that sprang across the fiery Enji.

Enji: "Well?! What do you say, (L/n)?! Think you'll beat me this time around?!"

And, of course, as they turned their sights to (Y/n). They were, like always, greeted by a hearty smile.

(Y/n): "Now. Now. Enji...There's no need to second guess yourself. Of course, I'll win! Ha! Ha! After all...I'm going to be the Number One Hero!"

Enji: "Number one hero? Ha! Don't make me smile! It's pathetic!"

(Y/n): "Make you smile? Please! I think everyone around here knows Enji, when it comes to smiling...I'm the one who does it best."

As he spoke those words, (Y/n)'s grin only widened, his body getting into a battle stance...As steam rose from his body...

[And there we have it! All done! This chapter came and went rather quickly. I originally thought to do something longer but I feel this was a perfect chapter to wrap up these little points I wanted to bring up. And it also perfectly sends us flying forward into the next part of this story which I like to call... 'Smiles & Gunpowder ARC' But what could that mean? Only one way to find out.

But with that being said, thank you all for reading, I hope you enjoyed, and I hope to see you all next time!]
