"Settle down everyone! Aizawa sensei would be here any moment now." Iida instructed his classmates. Everyone in the classroom partook in the commotion ongoing in the class. Be it the girls conversating with each other or the boys pranking one another and messing around. "Kaminari, Kirishima! You are making a ruckus over there! Bakugo! stop yelling at Todoroki. Hagakure and Ashido, You are making a noise with your squealing!" Iida continued as he robotically chopped the air.

"Damn it Four eyes! Mind your damn business!" Bakugo shouted at the class president then continued shouting at Todoroki who looked at him with a poker expression.

'It's been thirty minutes now and there's no sign of Mr Aizawa. The class is in upheaval and no one is listening to Iida.' Yaoyorozu thought as she sighed with a worried expression. She stood behind the lectern while Iida moved around the class prompting the others to discontinue such unethical behaviour.

"Kaminari! Sero! Stop shouting! This is a classroom!" Iida yelled at the two.

"But you are shouting to Iida." Sero sneered rendering the dark blue-haired boy's shoulder to slump in defeat. 'I've failed a class rep.' He thought somberly. Midoriya walked up to him placing a hand on his shoulder.

"Don't worry Iida. I'm sure Mr Aizawa will turn up soon." He reassured. True to his word, The door opened revealing Mr Aizawa in the doorway with a bandage wrapped around his forehead with his usual yellow sleeping bag hanging on his shoulder. His eyes landed on his troublesome students who were already seated quietly. Gradually, he came into the class standing in front letting his gaze linger on them for a few seconds then tore his gaze from them and fixated his eyes on the board.

"Aizawa sensei..." Uraraka raised her hand. She stared at her teacher with concern.

"I'm sorry for being late. There was something I had to take care of yesterday. Recovery girl had to check on me again this morning." The man explained. The concerned faces of his students died down a bit.

"Was it a villain?" Ojiro didn't realize that he said it out loud. Aizawa looked in dismay seeing his students had eyes filled with curiosity. He knew that his students were like this.

"Some people were able to get past U.A. security yesterday without causing any alarms to go off."

"So it was a villain."

"Maybe it was a small-time villain."

"No small-time villain could get past the school security, dumbass."

"Then could it be_" Todoroki finally spoke.

'The league of villains'. Everyone expected an answer from their teacher. The man activated his quirk hoping it would shut them up while he explained.

"If it's what you were thinking then no." He remarked earning grateful sighs from the class. 'If it wasn't the league then who?'

Again, the teacher explained. " The suspects are being interrogated later today. They were found by Monoma and Kendo from class 1B stating that they were found unconscious in the school hallway."

Midoriya felt uneasy by this statement. It was not every day that some villain would be able to breach here in and out without triggering the alarms. The first time it happened it was the so-called news reporters that kept bugging him about All Might being a teacher at U.A.

"Could they have been warped here or teleported? That seems unlikely given that Kurogiri of the league has been imprisoned in Tartarus but the league couldn't have gotten him out of there would they? If not, there might be someone else out there with the same quirk who turned out to be a villain..."

"I CAN HEAR YOU MUTTERING DEKU!" Bakugou said in a loud whisper but you could tell he was irritated.

"Oh! Sorry, Kacchan." Midoriya apologized with a hint of embarrassment.

"Wonder what type of villain was able to injure Mr Aizawa if it wasn't the league?" Sero commented.

"Yeah, That is true. Guess they aren't like the regular ones huh?" Kirishima responded.

"This information was supposed to be confidential among the teaching staff and those two from 1-B. I only told you this because I have been assigned to keep an eye on them. I trust you won't tell anyone else." The students nodded smiling knowing that their teacher trusted them in a way.

"With that aside, Everyone you are having a pop quiz now." Aizawa grinned." You thought I didn't hear all the noise you made." Most of the class groaned.

"Are you kidding me?!" Mina yelled with a shocked expression.

"Seriously?" Kaminari groaned.

"Better short-circuit yourself than take the quiz, Jamming-whey" Jirou teased with a sly smile.

"That's mean Jirou."

EARLIER

The lights flickered for a moment before maintaining its bright state showing a dark mohawk-haired boy who was restrained on a chair with a wooden desk in the center of the room. There was a dark tinted glass frame in the corner of the room much to Genya's dismay. Suddenly, the door opened and closed shut immediately with the supposed 'demon' who will be interrogating him.

"So you are the first one I'll be interrogating with then." The detective said wearing a friendly smile. He took the grunt of his suspect as a yes. Reaching for his pocket, he pulled a notepad and a pen and sat opposite the teen.

Genya's eyes followed the man's body intently. " My name is Detective Tsukauchi Naomasa, I'm here to execute an investigation on you and your friends sudden appearance at U.A. in Musutafu yesterday." Genya was listening but most of his attention seemed to be on the glass on the other side of the wall.

Aizawa sighed tiresomely. His teaching periods for today had been altered given the situation. At least he doesn't have to deal with his students for a while now. He had other things to do. The Mohawk teen was fixating his gaze on the tinted glass like he knew something or someone was behind it. Out of the five slayers, he seemed to be the weakest in terms of combat.

"So can you please state your name and age?"

"Shinazugawa Genya, 16 years old." He grunted. The detective only nodded and proceeded to jot it down.

"So how were you able to get into U.A. without triggering the alarm? Does it have to do with your qu_?"

"Where are my friends?" Genya furrowed his eyebrows glaring at the detective. Naomasa coughed a bit taken aback by him being cut short. He ignored it nonetheless and answered.

"I assure you they are fine." Genya almost retaliated after the statement. He wouldn't call them his friends normally. He sees Zenitsu as an idiotic crybaby, and Inosuke as a stupid annoying boar who can't read, write, or even pronounce names, as for Kanao he didn't really familiarize her as a friend but saw her often in the butterfly mansion. The only one he could perceive as a friend would be Tanjirou. Although they had a rough start in the final selection and when he arrived at the swordsmith village. He soon acknowledged him during their fight with Upper Moon Four and accepted him as a friend despite how he was hot-tempered.

Given the fact that they were the only people he knew here, they knew each other in some way. He could consider it again.

"How can I be certain that you are telling the truth?" He barked at the detective who remained unfazed yet sighed in defeat.

"You have my word for it, kid. They are safe." The pro hero, Eraser Head entered the interrogation room.

"Yeah. Alright." Genya restrained himself from getting angry again. He had to calm down and think.

'These guys better watch out.' The teen grinned making Aizawa narrow his eyes at the boy.

'What is he contemplating about?'

"My name is Agatsuma Zenitsu and I'm 16."

Tsukauchi took note and wrote it down much to Zenitsu's confusion. He tilted his head to the tinted glass wall gaining attention from the detective.

"There's no need to worry. It's just the two of us." He reassured.

"How can I then hear two more people talking over there?" He scowled." I can hear them alright. I can't pretend that no one else is listening."

"Hmm... If you could explain... Is that your quirk?" The detective asked. Zenitsu had a puzzled expression.

"My quirk? Hmm... Inosuke does say that I tend to talk in my sleep a lot." Aizawa deadpanned while the detective sweat dropped.

"So how did you get here?" The detective moved along not bothering to continue about the quirk discussion. Obviously, nothing useful came out of it.

"Well, I can't really remember what happened. All I can recollect is that I woke up unconscious here." Zenitsu explained.

'He isn't lying. How odd.' The detective wrote a few things down.

'This guy... Can he tell lies?' Zenitsu thought glancing at the man who was ticking empty boxes on a sheet. He couldn't decipher everything he wrote properly with his hearing. He wasn't as good as Uzui but he still had a feeling of it. Which to him was something.

They didn't obtain anything from the girl. She kept on smiling but with a serious expression. She only stated her name and age.

'Tsuyuri Kanao. She's 16 years old.' Aizawa glanced at the girl with a deadpan expression. Once they asked for her quirk, she tilted her head wondering what they were implying.

As for the boar head...

"Let go damn it!!" Inosuke struggled on his chair. As restless as he was, Nezu and the two men had to restrain more. After he was satisfied with how much commotion he caused. He settled down. Inosuke sensed the presence of others nearby but he decided to get this over with since he wore out most of his energy yelling.

" Your name is Hashibira Inosuke..."

"The lord of the mountains, Hashibira Inosuke!" Inosuke angrily pointed out earning a sigh from the detective.

"And you are currently how old?" The detective asked.

"Huh? I don't know." Inosuke started shocking the detective. " Kentaro and Monitsu said I'm fifteen or something." He continued. Tsukauchi glanced at the slayer wondering why he refused to take off the boar mask.

"Okay, so what's your quirk?" There was a minute of silence between the two. The detective observed that the boar-headed boy was silent. Perhaps, he didn't have one?

"What's that? Can you eat it?" Inosuke asks without hesitation. Aizawa resisted the urge to facepalm and sighed while muttering incoherent words.

Last but not least was the burgundy-haired boy. Aizawa gave a heads-up to the detective to be careful around him. However, the boy had promised not to try anything so they removed the restraining devices.

Tanjirou felt like he would never get used to this place. He closed his eyes and sniffed the air gently then turned to the glass wall. ' Is there someone behind that wall?'

The three looked at the boy curiously as he sniffed the air. "Excuse me, someone is watching us.". Aizawa wondered if they all had quirks that were able to tell such things.

" Just pretend that no one else is here alright? It's just me and you." The detective smiled. Tanjirou hesitates a bit before nodding.

Tsukauchi gleamed for a bit. So far, he hasn't given him much issue compared to the rest. Soon, he coughed before asking him.

"Can you please state your name and age?"

"I'm Kamado Tanjirou and I'm 15 years old." The detective wrote that down.

"Can you please give me information about your quirk?" Tanjirou did a double take. 'My quirk? As in my characteristics?'. He is usually known for being hardworking and kind to a fault. But why would they want to know about that?

"Quirk?" Tanjirou looked dazed. The detective simply sighed a bit disappointed.

"So how did you and your friends get here?" The detective moved along.

"I'm not sure..." Tanjirou grimly replied.

"Okay, so what then do you remember last doing?" Tanjirou's expression turned darker to Tsukauchi's surprise. Aizawa noted that it was the same look the boy had when he first escaped with his friends but was different in a way. His hand was firmly gripped on the chair almost breaking it. He was shaking not with fear but rage.

Tanjirou could not get this burning feeling off his chest after he remembered. "I was rushing with my friend Tomioka-san to the Master's estate. It exploded before our very eyes before we could reach there." He faced down.

The three listened with rapt attention to what the boy was saying. It was confirmed that the boy was not lying as Tsukauchi wrote this down.

"When we got there with the other pillars. We saw HIM and Lady Tamayo stuck on his body. Before we could attack, we fell into what we assumed was a trap for us but then... Something else showed up engulfing me."

"Can you give emphasis to who you are referring to?" Nezu remained silent. He was interested in the matter after what he said. Aizawa looked on with eyes that pleaded for a response to the detective's inquiry.

"Kibutsuji Muzan. The progenitor of demons. My friends and I are from an organization that hunts down these demons. Although we are not recognized by the government." Tanjirou concluded that since they might be working for the government. They might consider him crazy.

'Demons?!'

Tsukauchi and the others had doubtful looks. The fact that they weren't also recognized by the government. Nevertheless, the slayer proceeded.

"It's true. Man-eating demons roam about freely at night. It might be shocking at first. That's why my friends and I must go and defeat him."

"What was the reason your Hashibira and Shinazugawa called us demons?" The detective needed to obtain as much information as possible.

Tanjirou looked up facing the man. He nodded before continuing." We thought you all were demons because of how you had supernatural abilities and the diversity of the people here." He sheepishly stated. " They can easily blend in here thanks to their blood demon arts. "

Tsukauchi sighed and looked at the time. It has already passed more time needed than necessary. He stood up from his desk, and at the same time, Aizawa and Nezu walked in.

"Thank you for relaying information to me, Kamado." The detective said.

Tanjirou waved his hand and bowed to the man. "I'm glad that I was helpful in some way." The three looked at the boy with the detective smiling before walking away.

"You can go now Kamado," Nezu called to the boy who smiled before nodding in response. Once he left, the two sat down.

Tanjirou left the room shutting the door behind him. As he was about to turn, he picked up two new scents. He turned seeing two figures approached him in their outfits. A tall man with blonde hair which was styled in a way he didn't know was possible. He wore a pair of stylish glasses too while the woman had raven hair with dark blue eyes.

"Yo little listener!" Tanjirou remembered that one. He was there when they fought him and Eraserhead.

"Hi there. You must be that kid with his friends who appeared at U.A. yesterday. Am I right?" Midnight began. Tanjirou nodded in response.

"Pleased to meet you. I'm Kamado Tanjirou." He introduced bowing at a ninety-degree angle.

"Woah! No need to bow now. The hero name's Present Mic." Tanjirou felt his ears throbbing in and out. ' This man's voice is loud!' His head felt fuzzy.

" It's Midnight." The R-rated hero said seductively. Although Tanjirou felt different since he had nowhere he was. The only thing he knew was that they were in a place where people had supernatural abilities like demons but were not demons.

For some reason, he still felt troubled. Not just because of his disappearance but since he has no way of reaching his only family left.

' I will turn you back to your human form. Nezuko, I swear...'

"These kids are rather odd. Given that their dress code and the way their body language appear to be guarded. What do you think Aizawa?" Nezu asks facing the black-haired man.

"They are skilled though. In terms of hand-to-hand and physical combat. They do not know quirks either." Aizawa says recollecting their previous encounter with the slayers.

"After our first encounter, they reacted strongly despite having no idea of what was happening. I guessed that they were trained fighters with swords."

With that, the principal faced him with a small smile on his face. Aizawa knew that look that the rodent gave him. It just had to be him.

'Just my luck.'

#Preview

" I wonder what rank I will get this time around." Mina pouted with a depressed aura around her. She faces her oddly quiet friend.

"What do you think you'll rank?"

"Hagakure?" Hagakure thinks back to a boar-headed boy and his friends running past them. She shook her head hoping she was not going insane by imagining things.

"Hagakure. You've been quiet." Mina stated. Hagakure finally snapped back to reality.

"Oh! Sorry. I lost you there for a second."

"You've been spacing out lately. "

"My bad." The invisible girl waves it off but Mina does not see it. Soon, a shadow comes over the two. Mina and Hagakure slowly turn back to see their homeroom teacher with his quirk activated.

"Aren't you two supposed to be having class?" The two gulped nodding. He didn't need to repeat himself as they began walking away.

"Next, Chapter 6: The Kamaboko Squad." Eraserhead sighed and walked in another direction.

"The Kamaboko squad?" The two girls thought.
