Genya had every right to flip the table before him—if he could. The light bulb flickered before briefly settling in a steady glow. Only walls enclosed the room aside from the dark-tinted glass frame on his left, much to his dismay. The Mohawk-haired teen was restrained on a chair with the table in the center of the room.
Suddenly, the door opened and closed shut immediately with the supposed 'demon' to be interrogating him.

"So you are the first one I'll be interrogating then." The detective approached him, took a seat, and wore a friendly smile. He took the grunt of his suspect as a yes. Reaching for his pocket, he pulled out a notepad and a pen. 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 window.

Eraserhead let out a tiresome sigh. The breaching teens had woken up an hour ago, about five in the evening. The man was lucky, given that his students had finished their classes for the day. Now, he could deal with whatever situation this was. He watched from behind the glass, white bandages peeking through his bangs covering his forehead— a testament to the headbutt from earlier. Nezu watched silently, nestled on his shoulder.

Out of the five, this kid had the least combat skills from what I've seen from them earlier. Aizawa mentally surmised, placing his hands in his pockets.

Genya's eyes squinted at the dark-tinted frame, his lips pressed together like a thought itching in his mind.

"So can you please state your name and age?" Tsukauchi began with a click of his pen.
Genya snapped his head to the man. "Genya Shinazugawa, 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 quirk—?"

"Where are my friends?" Genya cut him off in a sharp tone, maintaining eye contact with the detective.

Tsukauchi coughed lightly, taken aback by him being cut short, and proceeded to answer. "I assure you they are fine."

Although Genya hadn't interacted much with anyone but Tanjirou. His first interaction with Zenitsu would surely leave a lasting impression on the blonde after the incident at the Wind Hashira's estate. The same goes for Inosuke, who ridiculed him for not being able to use breathing styles or the technique. As for Kanao, he rarely spoke to her but saw her from time to time when he stopped by for checkups in the Butterfly Mansion.

The Kamado siblings, bless their sweet souls, accepted him. He found it absurd how easily chill Nezuko was slowly warming up to his presence. It was more absurd in Tanjirou's case. Once formerly choking the boy, and look, they are good friends. One day, he'd look back and laugh about it...after apologizing, of course.

Despite all that, given the fact that they were the only people Genya knew here. Still, they were his allies. He could consider it again and perhaps try to be more interactive with the rest of his group.

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

"You have my word for it, kid. They are safe." Eraser Head entered the interrogation room, deciding to step in.

"Yeah, Alright." Genya clicked his tongue and begrudgingly listened.

These guys better not pull any stunts. He thought, looking away from the curious looks of the men.

・・・・・

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

Tsukauchi kept record of all the information he was getting in his notepad while Zenitsu took that short time to check his surroundings. His eyes landed on the tinted glass, with his ears twitching involuntarily.

The detective looked up from his notes, reassuring the boy. "There's no need to worry. It's just the two of us."

"Then why can I hear two more people talking over there?" Zenitsu scowled, pointing to his left. "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 leaned forward but only got a quizzical look.

"My quirk? Hmm... Inosuke does say that I tend to talk in my sleep a lot."

Outside the room, Aizawa gave an unimpressed stare while Nezu chuckled softly. Tsukauchi broke a sweat deciding to proceed.

"So how did you get here?"

"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 tapped his fingers on the chair rest. He glanced 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 about it, which to him meant something.

・・・・・

They didn't obtain anything from the girl. She held a perfectly calm smile , soft and kind, but her eyes held something else entirely different. She didn't say a word and barely even gave in into their demands of yes or no topics. They were beginning to wonder if this is just her normal self or if she's just not willing to answer.

Kanao Tsuyuri. She's 16 years old. Aizawa peered through the glass frame at the girl with crossed arms. Once they asked for her quirk, she tilted her head, wondering what they were implying. And As for Inosuke...

"Let go, damn it!" Inosuke struggled in his chair. As restless as he was, Nezu and the two men had to restrain him more. After he was satisfied with how much commotion he caused, he settled down. Inosuke sensed the presence of Aizawa and Nezu nearby outside the room. With a small grunt, he decided to get it over with since he'd already worn himself out yelling.

"Your name is Inosuke Haishibira..."

"The lord of the mountains, Hashibira Inosuke!" The wild slayer cackled, his chair almost falling backwards till he quickly caught himself after flailing his feet wildly.

"And you are currently how old?"

"Huh? I don't know." Inosuke started, spurring creased brows from the detective. "Kentaro and Monitsu said I'm fifteen or something." He continued.

"Is that mask very important to you?"

"Yeah, why?"

"You haven't taken it off since you stepped in here. Don't you feel the need to take it off?"

"Nope."

"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 asked, with no sign of hesitation. Eraserhead resisted the urge to facepalm before he sighed while muttering incoherent words.

・・・・・

Last but not least was Tanjirou. 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 his restraints.

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?

Tsukauchi looked at the boy curiously as he sniffed the air. "Excuse me, someone is watching us."

Seems they all have a keen sense,Aizawa mused.

"Just pretend that no one else is here, alright? It's just me and you." Tsukauchi insists gently with a small smile. Tanjirou hesitates a bit before nodding.

Tsukauchi was pleased. His face lit up for a bit. So far, the boy hasn't given him much issue compared to the rest. Soon, he cleared his throat and asked.

"Can you please state your name and age?"

"I'm Tanjirou Kamado, 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 hard-working and kind to a fault. But why would they want to know about that?

"Quirk?" Tanjirou tilts his head with dotted eyes. The man simply resigned. Nothing new apparently, though he continued his questioning.

"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 initial shock. 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 with rage.

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

The three listened closely. It was confirmed that the boy was not lying, as Tsukauchi wrote this down.

"When we got there with the other Hashiras. We sawhimand Lady Tamayo stuck to 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. Like a void space."

"Can you give emphasis to who you are referring to?"

Nezu remained silent. His folded paws and impassive expression tell how invested he is now. 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 mentally ill, crazy even.

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." Tanjirou confirmed as if he knew their thoughts. "That's why my friends and I must go and defeat him."

"What was the reason your Hashibira, Agatsuma, 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."

"Sorry for the trouble we caused; if we had listened to you and had the chance to know you meant no harm, We wouldn't have taken action."

Tsukauchi hummed, then looked at the time. It has already passed more time 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 closed his notepad with a soft snap.

Tanjirou waved his hand and bowed to the man. "I'm glad that I was helpful in some way."

"You can go now, Kamado," Nezu called to the boy, who smiled before nodding in response. Once he left, the three 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 approach him in their outfits. A tall man with blonde hair, which was styled in a way he didn't know was possible. He wore stylish glasses, while the woman had raven hair with dark blue eyes.

"Yo, little listener!"

Tanjirou remembered Present Mic. He was there when they fought him and Eraserhead.

"Well hello 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 make your acquaintance. I'm Tanjirou Kamado." He introduced bowing at a ninety-degree angle.

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

"The R-rated heroine, Midnight." Midnight was introduced in a flirty tone. "Nice to meet you, Kamado."

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

Nezuko...He silently clenched his fists.

Meanwhile, back in the room with the three adults. Tsukauchi mentioned his findings and results to the principal and underground hero.

"I'll proceed with Sansa in investigating the cause of their appearance. They were honest. The only complication is how far back they date—likely the Taisho period." Tsukauchi paused briefly, sensing their rapt attention.

"So, these kids time traveled. What else?" Aizawa asked.

Tsukauchi nods, flipping a page. "Yes, but the absence of quirks or signs of its evolution means that this is different. Dating back to the 20th century, there was nothing in our history books recorded about demons."

"And you're absolutely sure this isn't some sort of prank?"

Naomasa shook his head. "My truth quirk is purely based on facts." He closed his notepad. "As much as I'd like to deny it, what they said isn't to be in denial. Aligning with how we run things here and our history, there's nothing in our given record database or history on demons and demon hunters... For all we know, we could be dealing with something else—possibly an interdimensional breakthrough, if I were to speculate."

Nezu's eyes gleamed if only for a moment. "The phenomenon that is known as interdimensional hopping. I've always been fascinated by such theories, but it seems like this might be our likely target." Turning to the detective, he gave a grateful nod. "Thank you for your assistance today, Detective Tsukauchi."

Tsukauchi propped his hat on his head, heading to the door. "I'll see what I can find on quirks related to space and time and notify other pro heroes of any information they could spare."

Once he left, Nezu turned to Eraserhead. "These kids are an interesting bunch, youngsters all the way back from the taisho period, demon hunting, surely a rough past given their guard. What do you think, Aizawa?"

"They are skilled in terms of hand-to-hand and physical combat. They do not know quirks either." Aizawa answered, recollecting his 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 an uplift on the corner of his lips. Aizawa knew that look that the stout gave him. It just had to be him.

"Alright then, shall we get their student IDs?"

Just my luck.

#Preview

"A boar-head?" Hagakure surmised, deep in thought. She sat in the common room, staring at the ceiling. The moment when she'd seen the five slayers running from their teacher replayed in her mind like a broken record. Why did the thought pester her? She has no idea.

"Tooru?" Mina stopped, sliding on the couch seat next to her friend. "You okay? It looks like you've got something on your mind."

Hagakure straightened, stretching her invisible arms as she quickly dismissed. "Just thinking back on our training earlier today."

Mina gave a skeptical look but didn't push further. "If you say so. Next chapter 6: The Kamaboko Squad."
