The demon slayers watched the upper moons as they scratched at their skin. "Huh, not bad..you managed to attack me." Gyutaro said with his back facing Kiyatai. The woman narrowed her eyes at him without saying a word. "Even though I was going for the kill. Good for you, man." he said as he turned around to face the demon slayers.

Kiyatai scoffed and tightened her grip on her weapons. "Good for you." he repeated. "that face of yours..nice. I like your skin, too." Kiyatai looked at him in disgust. "do not compliment me." she said with venom lacing her voice. "Oh? Why not? You're very strong, and I bet you get tons of attention from the guys too, don't you?" he said. She cringed at his words. "I have a partner, you bastard." She said as she narrowed her eyes at him.

Daki was still crying and sniffling on the floor. "I see..you're very lucky. I envy you." Gyutaro growled. "How I envy you! Would you mind just DROPPING DEAD??" he yelled as he tore away at his flesh. "In the most agonizing way at that! Like getting skinned alive. Or maybe getting your stomach slit open!" He said with a crazed grin.

"And one more thing-!" suddenly, he was cut off by his sister. "Brother! It wasn't just her! There's more! Kill the ones who stabbed me, too! Promise me!" She shouted with a frown. "I've been toiling away, and yet..I've really been giving it my all! All by myself!" She said as she began crying again.

"And yet, everyone got in my way and bullied me! They all ganged up on me and bullied me!"
She wailed even louder. her brother glanced back up at the demon hunters. "I see! I see! That's unforgivable for sure!"

he kept scratching at his skin. "My sweet little sister was doing her best with what little brains she had." His wounds began regenerating. "So I'll massacre everyone who had the nerve to bully her. Time to exact it, that's my way." he said with narrowed eyes. "Ill exact the same damage you inflicted on me for sure."

he got into a fighting stance as he lifted his weapons in the air. "You're going to spin round and round when you die. BECAUSE MY NAME IS GYUTARO!!" He screamed.

And without warning, he threw his weapons at the demon slayers, though they were quick to dodge them. "How envious I am..you really are a powerful hashira, aren't you? Protecting those humans..and showing off like that..I envy you." Kiyatai rolled her eyes and lifted her gun up. "Shut it. I don't care to listen to your ranting. You'll never be as strong as us."

Gyutaros eyes narrowed. "Did you just say..I'll never be as strong as you?" he said as he began clawing at his face. "ARE YOU KIDDING ME?!?!" He screamed. "THATS UNFORGIVABLE!!" Blood began to pour out of his hands as it wrapped around his sickles.

"BLOOD DEMON ART.." Kiyatai quickly got into a fighting stance, a stern look painting upon her features. Gyutaro swung his weapons around. "FLYING BLOOD SICKLES!!" he screamed as the blood flew straight towards her. She instantly raised her katana and began slashing at the blood relentlessly.

"so..you can bend the slashes at will? how impressive." she said sarcastically. she placed her gun back into its holster. And without warning, she disappeared. Gyutaro looked around in confusion, trying to find her. But suddenly, a pair of shoes met his back as he was sent flying forward. he crashed into a wall near the villains.

Kiyatai narrowed her eyes at him before facing the demon slayers. "Koizumi, kamado, agatsuma, Kwixiri, and hashibira. Go help the other students with the villains. Me and Yamiki will take care of this." The teenagers quickly nodded before running off to find their classmates.

Kiyatai looked at Yamiki with a stern expression. "You take care of that brat, while I take care of the small fry." She said. Yamiki nodded at her. "Got it." she shouted. Kiyatai turned back to the demon, who was regaining his balance.

"We need to cut their heads off at the same time. If we don't, they won't die." Kiyatai explained as yamiki narrowed her eyes. "I have a plan. Distract the brat and lure her to me. When I say switch, you back away and let me attack her. Then, when I say now, you cut off her head. Got it?" Kiyatai order with a scowl. Yamiki nodded at her. "Alright, I'll do it."

Kiyatai looked forward without saying a word. And with that, she ran forward and kicked Gyutaro in the head Mt. Lady style. his skull shattered on impact with the wall. "ACK!" Gyutaro yelled as his broken bones pierced his dead flesh.

Kiyatai quickly backflipped away from him and stood proud and tall. "Come on. get up and fight me. Or are you too much of a pussy?" She said mockingly with a smirk, her bangs casting a shadow over her face.

Gyutaro weakly stood up and gripped onto his sickles. "I'll kill you and all of those people." He said, anger lacing his voice. "Oh? I'd like to see you try." she said. "Gold breathing, fifth form: Aurous lightning!" Lightning surrounded Kiyatai as she closed her eyes. She jumped into the air  and lifted her sword. She let herself fall a little before slashing down onto the demons chest.

Agonizing pain filled the demons body as he screamed. she took his distraction to her advantage and punched him in the face. gyutaros eyes widened In shock, but Kiyatai didnt give him any time to react. She elbowed  him in the face. "Gold breathing, First form: Gilded blade!" She quickly slashed his chest once again. Gyutaros jaw dropped as he tried moving, but he couldn't. He was paralyzed.

Kiyatai smirked. "SWITCH!!" she screamed at Yamiki, The ghost hashira instantly stopped attacking daki and moved out of the way. Kiyatai ran at daki and used her first form again, paralyzing her as well.

Daki fell on her knees as she began crying again. Kiyatai ignored her and ran back to gyutaro. she stared at him in disgust for a second before screaming. "NOW!!"

And with that, the two hashiras sliced their heads off with ease.

The siblings heads rolled next to each other. they began arguing and screaming at one another. But they suddenly started to cry. Kiyatai scoffed at them and watched as they turned into ashes.

Yamiki turned towards the gold hashira. "We did it." Kiyatai glanced at her with a smirk. "No shit, we're strong as fuck." Yamiki laughed a little at her words. "Alright, we Better go help the others." she said with a soft smile.

Kiyatai nodded and darted towards the group of people. Yamiki shook her head playfully and ran after her.

little did they know..everyone was watching them the entire time.

The hashiras quickly ran up to the others and stood in front of them. "All might finally showed up?" Yamiki said with an annoyed expression. "Took him long enough." Kiyatai grumbled as she cracked her knuckles.

"N-nayoushi! Yamiki! Who were those people you were fi-" Midoriya said before getting cut off. "None of your damn business, kid." Kiyatai said, shutting him up. He shriveled up in fear before backing up away from her.

The gold hashira turned to the other teenagers. "Who are these freaks? And what do they want?" Kirishima turned towards her with worry painting his face. "They're the league of villains, and they're here to kill all might.." He said, barley above a whisper.

Kiyatai scoffed. "That's a corny ass name. I'll probably call them the league of vaginas." She said with a smirk while eyeing all might and the nomu. The others laughed quietly at what she said.

Then, the two clashed their fists together without warning, creating a huge gust of wind that pushed the others backwards. While the demon slayers just stood there unfazed.

Suddenly, Zehira and the others ran over to the hashiras with a few other students following them. "Nayoushi-San, Yamiki! Did you two defeat the uppermoons?" She said with a worried tone. Kiyatai looked at her and smirked. "Of course we did." she said proudly.

Yamiki turned to her friends. "Are you guys okay? You didn't get injured, did you? Were there any other uppermoons? Or demons?" she asked. Tanjiro smiled at her. "Dont worry, we're okay! And no, there weren't any other demons." Yamiki and kiyatai sighed in relief.

Todoroki raised his eyebrow in confusion. "What's a de-" "shut the fuck up."
Kiyatai glared daggers at him. todoroki just narrowed his eyes at her and looked away. The hero and the nomu continued to fight each other relentlessly as the slayers watched the fight intensely. All might slammed the nomu into the floor, creating a huge crater in the ground.

"Hey villain, have you ever heard these words?" He called out to it. The slayers narrowed their eyes, waiting for him to defeat it. "Go beyond!" All might reeled is fist back.
"Plus..." he finally punched the nomu straight in the gut. "ULTRAAA!!!" all might screamed with all his might. The power of his punch sent the creature flying into the air, causing it to break through the ceiling and vanish into the sky.

The slayers stood there with a satisfied expression. "Well shit, He's good." Kiyatai said with a raised eyebrow. "Woah!! He's really powerful!" Tanjiro said with a wide smile. "He kinda reminds me of gyomei-San!" Zehira said with a grin. "I WANNA FIGHT HIM!!" Inosuke screamed.

"He's amazing!" Iku said with a smile. "I didn't think quirks could be this strong." Yamiki said with a shocked expression. Zenitsu stood silent, since he was still asleep. "Is this a comic book? It's like he nullified the shock absorption. His brute strength is crazy." Kirishima said.

"What insane power. Does this mean he rushed at him so fast he couldn't regenerate?" Bakugo asked in amazement, but he didn't show it. "All might.." Midoriya whispered, he was obviously worried about his teacher.

The smoke that surrounded all might faded away, revealing him standing in his previous fight stance. "I really have gotten weaker..in my prime, five hits would've been enough." he said as he continued to gasp for air.

He stood up straight and placed his fist in front of him. "But it took more than 300 hits." he said with a forced smile. Midoriya sighed in relief as all might turned towards the handy villain.

"Now, villains..im sure we'd all like to end this as soon as possible." The blue haired guy stared at him in rage as he began to scratch at his neck. "Hey, what's going on? He's not any weaker at all. Did that guy lie to me?" he said with an aggravated tone.

"What's wrong?" All might suddenly called out. "You're not coming? You said you'd clear this or something, right?" All might glared at him. "Come and get me if you can." The villain stepped back In fear as he trembled.

"All might.." bakugo whispered in shock. "As expected, it looks like there is no need for us to fight." todoroki said as midoriya gasped at all mights current condition.

"You guys! We should get out of here now! It'll be worse if we end up getting taken hostage instead!" Kirishima called out to Midoriya and the demon slayers. no one responded.

It was quiet for a minute, before all might broke the silence. "Well? What's wrong?!" He yelled at them. The villain grew irritated, and started to claw at his neck again. "If only I had nomu..that guy would've been able to go up against him without thinking about anything!" He yelled as he growled in anger.

"Tomura shigaraki! Please calm yourself! Looking carefully, I see that he has definitely weakened from the damage of nomus attacks. Besides, the children seem to be frozen in fear." The Misty man said calmly.

"We still have underlings who can be used. There are likely only a few minutes left before reinforcements come. If you and I work together, we still have a chance of killing him." the handy villain calmed down at his words. "Yeah...yeah, yeah..that's right..that's right..we have no choice but to do it." He whispered.

"I mean, we have the last boss right in front of our eyes." He said as the other villains woke up and faced the students. "All might will do something about the main bad guys. Lets go help the others!" Kirishima called out as he activated his quirk.

Todoroki turned to the side. "Midoriya?" He said But the green haired boy didn't respond. And without warning, the handy villain rushed towards all might. "This is revenge for nomu!" He yelled as he reached his hand out to the number one hero. The mist guy created a portal and sent it towards him as well. But all might stood still. Not moving an inch.

Suddenly, Midoriya activated his quirk and jumped towards the villains. "YOU DUMBASS!" Kiyatai screamed at him. "MIDORIYA!" Kirishima yelled. but he still didn't listen.

Midoriya tightened his fist and reeled it back. "GET AWAY FROM ALL MIGHT!!" He screamed at them. But before he could land the hit, the blue haired villains hand stretched out through a portal and aimed right at his face.

Zehira suddenly disappeared from her spot as she ran to save Midoriya. She quickly jumped in and tackled him to the floor before the hand could cup his face. they tumbled onto the ground as Zehira quickly recovered and got into a fight stance. before the handy villain could move to attack her, Two bullets shot him in the hand, and in the arm. Everyone gasped and looked towards the shooters.

There stood the hero, snipe. with a gun in his hand, and Kiyatai, who glared daggers at the villain. She gripped her gun even harsher as she stared at him with a crazed expression. Zehira and Midoriya looked at her and the hero in shock, as more hero's began flooding into the entrance of the USJ.

"Sorry everyone for being late! I gathered all who were immediately available." The principal yelled out to the others as he sat on another hero's shoulder. "I, TENYA IIDA, CLASS 1-A REPRESENTATIVE, HAS NOW RETURNED!"
He screamed as many other hero's walked up behind him. The minor villains began yelling in frustration as they desperately tried to attack the hero's, but that was a dumb move, really.

A yellow haired hero walked forward and took a deep breath before activating his quirk. "YEEEEEAAAAAAAHHHHHHHH!!!!!" The villains covered their ears and screamed in pain as they flew back from the high frequencies. Another hero activated his quirk and summoned clones of himself.

The slayers sighed in relief. "Took them long enough." Kiyatai said. The slayers ran towards Zehira and Midoriya and stood in front of them in a protective stance. "Awh man..they're here."
The handy villain said as he backed away from the demon slayers. "It's game over now. Shall we go home and try again later, kurogi-" he was cut off by multiple bullets being shot at him. Kiyatai and snipe continuously shot his body. But the bullets were blocked by the Misty villain, who covered the handy villain with his quirk.

The Misty villain attempted to cover his leader completely with his quirk, but was stopped by thirteen, who used her quirk on him. But unfortunately, the villains managed to escape.
everyone stood silent. not knowing what to do or say. Midoriya trembled on the ground as he attempted to get up. "I..wasn't able to do anything.." he whispered.

"That's not true." All might suddenly said. Midoriya and the slayers looked up to see all might. Half of his body was scrawny and weak, while the other half was strong and built. "If it weren't for those few seconds you all bought me, I would've been killed." He said in a whisper. "you saved me again." Midoriya gasped as he began to tear up. "All might..!" The said man smiled widely at his successor.

The demon slayers watched their interaction with small smiles. "I'm..so glad you're okay!" Midoriya cried. The slayers sighed in relief. It was finally over. They all turned to walk away, but kirishima interrupted them. "Hey! Everyone!" He yelled for his classmates. "Oh, kirishima.." Midoriya said as he laid on the ground. "Are you guys alright?!" He asked as he ran towards his friends. Midoriya saw all mights expression and began panicking. "K-kirishima! Wai-!" Midoriya yelled as he reached out his hand.

Kirishima gave him a confused look, but before he could run any further, a huge wall of cement  grew in front of him, shielding his vision from all mights true form. "We want to make sure that all the students are safe, so please gather in front of the gate." The hero, cementoss said. The lie slipping off his tongue with ease. "We will deal with the injured here" he said plainly. "That makes sense! Roger that!" Kirishima shouted before running off. "Hey! He said to gather in front of the gate!" He told bakugo and todoroki.

Midoriya and all might visibly relaxed at that.
Cementoss walked up to the now scrawny man as all might turned to him. "Thanks. You saved me, cementoss." The said man just smiled and put his hands together. "I am a fan of yours, too."

Cementoss! Quirk: cement.

He can manipulate the cement he touches like clay. He's super strong in modern society!

"Let's get you to the nurses office while keeping you hidden. But man, you act recklessly every time, huh?" Cementoss said with an unimpressed tone. "If I didn't act recklessly, I would've been killed." All might said as he brought his hand to his face. "That was how strong the enemy was." he grumbled as he wiped the blood off his face.

It went silent for a few moments, before-

"Pfft."

A sudden laugh cut the silence as Kiyatai attempted to stop her giggles. "Who knew the strongest hero in Japan was also a scrawny toothpick?" She said as she side eyed him with a smirk. Zehiras jaw dropped as the others looked at her in shock. Zehira covered her mouth and hid her face in Kiyatais haori.

"s-stop- I can't laugh-!" She whispered. Her giggling becoming louder. Tanjiro looked at the others and began laughing too. Soon, the area erupted in laughter as they continued to joke about all might being a fraud. Hell, even Midoriya and all might joined them as well.

"God, that was great." Kiyatai said as she wiped a tear from her eye. "You're such losers, you know?" Kiyatai joked with a grin. Zehira giggled as she leaned on kiyatais shoulder. Kiyatai smiled at the girl and patted her head. "..you guys did great out there, I'm proud of you." She said as she looked at the rest of the demon slayers. Tanjiro and Zehira gasped. "REALLY??" they said with wide grins. "..no."
She said with a smirk. everyone's jaws dropped as she began laughing again.

"I'm just joking. Yes, I'm proud of you. You did pretty good too, small might." She said as she turned to the scrawny hero. The said man laughed at the nickname. "Thank you, Kiyatai. And thank you all for protecting the students."
They demon slayers shook their heads. "Dont worry, sir! It's our job." Iku said with a smile. "Yeah. I'm glad no one was killed." Yamiki said as she messed with the hem of her haori.

"CAN I FIGHT THEM NOW?!?" Inosuke screamed as he jumped up and down in determination. "NO." Everyone yelled. "UGHHH" Inosuke groaned in frustration. he turned towards Zenitsu who stood there, still asleep. "WAKE UP ALREADY MONITSU!!" Inosuke screamed as he slapped the back of zenitsus head. The boy jolted awake with a terrified expression. "GAHH!!! WHERES THE DEMONS?!? IM SCARED!! I DONT WANNA DIE!!!" He screamed in fear. Zehira laughed and patted his back. "Dont worry, Zenitsu! They've been defeated already." She said with a smile.

"Alright, kids. We should get going. before anyone gets suspicious of us." All might said with a smile as he stood up from the ground. "Got it!" The others said at the same time. Kiyatai walked towards midoriya and picked him up with ease. Midoriyas face flushed bright red as he began panicking.

"N-nayoushi! W-what are you doing?!" He yelled in embarrassment. Kiyatai looked at him with a dumbfounded expression. "I'm carrying you, idiot. Your legs are clearly broken." Midoriya stopped freaking out and looked at his legs. "Oh, yeah..thanks for carrying me!" He said as he smiled widely at her. Kiyatai just nodded. "Dont mention it."

And with that, the hero's, students, and demon slayers walked out of the building.

TIME SKIP!

"...24, 25, 26. Other than the boy with both legs seriously injured, everyone else seems unharmed." A detective said as he stood in front of the students. Everyone sighed in relief before smiling. The students began talking to each other, while a few others turned to the demon slayers with confused looks. "Hey, who were those people you were fighting?" Kirishima asked them as he rubbed the back of his neck. "Yeah! I saw you and yamiki fighting them, too!" Mina said. "Me too!" "So did I." Everyones voices layered over each other's.

Kiyatai looked at them with a stern expression. She watched as the other students began crowding around her and the other demon slayers, basically demanding answers. "Tori, send a message." She called out. Everyone looked around confused before a crow landed on the woman's shoulder. "What would you like to say, Nayoushi-sama?" The crow said.

The students looked at the talking crow in shock. "Tell oyakata-sama, that I must tell them who we are." she said as she glared at her classmates. "Very well, nayoushi-sama." And with that, the crow flew away.

"Lets have the students return to their classroom for now." The detective said, breaking the thick tension in the air. "We won't be questioning them right away, anyway, right?" He said.

The demon slayers took the distraction to their advantage as they quietly ran away from the area. They ran into the forest where they first arrived in this universe. They slowed down and waited in silence. After a good minute, a portal formed, and a familiar demon slayer stepped out of it with a small smile.

"Hello everyone." Haruka said as she placed her katana back in its sheath. The demon slayers greeted her as Kiyatai walked forward. "What did oyakata-sama say?" she asked. Haruka looked up at Kiyatai and placed her hands behind her back. "He said you have permission to tell the class, and only the class." she said calmly. "We also heard that you defeated uppermoon 6? Congratulations."
Haruka said.

Kiyatai frowned, "we did, but we also found out that three other uppermoons are here as well. Uppermoon 2, and uppermoon 3. Kibutsuji is here too." Kiyatai said with an aggravated tone.

Harukas eyes widened. "..I see. I'll inform oyakata-sama about this now. Good luck on your mission." She said as she bowed down. "Thank you." Kiyatai said with a nod, and with that, the demon slayer stepped back into the portal and disappeared.

IN AN UNKNOWN LOCATION.

A portal suddenly appeared in an abandoned bar. A certain villain covered in hands, laid on the floor. "Ouch..I was shot in both arms and both legs...we lost completely..even nomu was defeated! All the underlings were defeated in an instant! Those kids were strong..especially those miserable demon slayers." He said as he groaned in frustration.

"The symbol of peace was healthy..and those demon slayers were stronger than you said! You were wrong, master!!" He yelled.

"no, we weren't. We were just not prepared enough. And those demon slayers were in fact strong, weren't they? We underestimated them. It's good that we did it under that cheap 'league of villains' name." The unknown voice said through a tv screen.

"By the way, what about master and my joint creation, nomu? Was he not retrieved?" Asked the man. Kurogiri stared at the tv. "He was blown away." He said.

"What?!?" The mysterious man yelled. "More precisely, without coordinates to his precise location, I could not find him, even with my warp." Kurogiri said as he began walking forward. "I did not have time for that." He said as he stood in front of the tv.

"After all we did to make him as powerful as all might! ...well, I suppose it can't be helped. That's unfortunate." The man said.

"Power..that's right. There was one child who was as fast as all might." Shigaraki said as he laid on the floor, blood still pouring out of his wounds.

"Oh?" The mysterious man said. "If he and those stupid demon slayers haven't gotten in the way, we might have been able to kill all might." He said as he gripped the floor, his nails damaging the wooden planks.

"...speaking of demon slayers." Another man said. His mere voice sending chills down everyone's spine. "what have they done to my uppermoons?" The man said. His bright red eyes glowing in the darkness.

"...they killed them, muzan."

the said man tightened his grip around the cup of whiskey he held. he crushed the glass with ease. "I see..I'll fucking destroy those slayers, and I'll devour each and every one of them." he said, venom lacing his every word. shigaraki stared at him in pure terror as the demon king glared at him.

the man stepped out of the dark corner, revealing himself. He was a nicely dressed man, who seemed to be in his 20s. He had bright red eyes that could kill anyone, just with a single glance. His black curly hair swayed as he walked towards the villains. he stood above the young villain as he glared daggers at him.

"If you ever let any of my demons die again, I'll fucking murder you." Muzan said as he stepped on the villains back. Shigaraki trembled underneath him. "I understand, sir.." the villain whispered.

"..good." muzan said as he stepped off of him. and with that, he walked into a different room, not sparing another word.
