Nezu, Izuku and Aizawa stared at the newest member of the investigation crew. The room was filled with an awkward silence.

"So, what am I doing here?"

"Good question. Nezu, what is he doing here?"

"Nezu-san, what do you have in mind?"

The Chimera cackled and sipped his tea.

'Where did that come from?' the others in the room thought in confusion.

"Shinsou-kun, thank you for joining us. You are here because we need your help"

The purple haired teen with Gucci eyebags blinked in confusion. "Help?.... How can I?"

Izuku tilted his head curiously and looked at Shinsou, "Ne Shinsou-kun, what's your quirk?"

The other teen froze immediately and looked at his hands on the table, "It's brainwashing" he mumbled.

"Brainwashing?" Izuku repeated and looked at Nezu before facing the teen, "how does it work?"

"Um.. it's- uh, I need a verbal response to uh, activate my quirk. I can uh- command… them?"

'Damn! No wonder he's scared of us. People might've said that he's a villain,' the greenette thought.

"A verbal response..." Aizawa mumbled, "we can use that"

"That's an amazing quirk!!" Izuku exclaimed in delight while the purplette froze.

"Y-you think so?"

"Of course!! You can become an amazing hero with it!" The greenette continued and turned to Nezu, "so you're going to make him spill the truth by making Shinsou-kun control him?"

"W-wait!" Shinsou interjected, "truth? Who? What? Why am I here? What am I supposed to do?"

Izuku bit his tongue and briefly explained the situation to Shinsou who just nodded in daze. "But I can't make them talk"

The others, except Nezu, looked a little shocked. "What do you mean, Shinsou-kun?"

"My quirk, it's actually just to control people's physical actions. I can't make them do complex tasks that involve excessive brain activity- like talking or writing..."

"That's… " Izuku trailed off.

Nezu, however, chuckled and looked at Izuku, "Izuku-kun, I have a plan in my mind. For now, I want you to understand Shinsou-kun's quirk and then guess my plan. Alright?"

The greenette nodded.

"Shinsou-kun, please use your quirk on Aizawa-kun"

"What?!!"

Aizawa just sighed and stood up, "do it, kid. It's alright"

"But-"

"Shinsou-kun, it's okay" Izuku assured.

The purple haired teen nodded and gulped before standing up as well. "Aizawa-san, what's my hair colour?"

"Purple"

Shinsou hesitantly took him under control and looked at Nezu. Izuku stared in awe at Aizawa's dazed state.

"I want you to command him to do certain things" Nezu said and sat on Shinsou's shoulders, "ask him to point to the person who was accidentally added to the group chat"

The purple haired teen looked confused but nodded. "Aizawa-san, point to the person who was accidentally added to the group chat"

Aizawa's hand rose on its own accord and pointed to Izuku. Izuku caught onto Nezu's plan.

"Subconscious" Izuku mumbled and Nezu cackled in happiness.

"Break the control"

Aizawa looked confused as to why his kitten was looking like a sadistic kid who just destroyed a toy shop and why Nezu was sitting on Shinsou's shoulders.

"Now, Aizawa-kun. Try your best to resist answering the next question. Alright?"

Once again, the poor sleep deprived teacher was under control and Nezu told the question to Shinsou while passing him a phone.

"Um, point to the person who stole your scarf?" He asked, showing a collage of the staff on the phone.

Aizawa pointed to Nemuri's picture in the collage and Izuku squealed in delight.

"I tried so hard not to answer but I did not have control over my actions" Aizawa grumbled after being released.

"So.. so you're telling me that you can actually think but you have no control over your actions. It's like, um, Shinsou-kun's quirk is overriding your brain and commanding it to do whatever he wants irrespective of your thought process" Izuku mumbled.

"That is right" Nezu remarked, "as to how he could identify Who's who, it depends on the subconscious memory. Aizawa-kun knows that you were added to the group chat and that Midnight stole his scarf. The brain uses this active subconscious to identify things even under control. For instance, you're commanded to exit the room. The subconscious helps you to identify that the object in your vision is the door or it supplied the mental map to the door. You will have no control over your actions and your active subconscious will guide you to accomplish the task assigned by the controller"

"That means..." Izuku's eyes widened, "the traitor isn't our priority! You want him to reveal the person who stole the information!"

"Exactly! We must interrogate the person who leaked the information as soon as possible. This traitor is adamant on keeping his mouth shut because he knows we need him but the person who leaked the information can be threatened. I'm leaving Aizawa-kun and Hawks for that part"

"Eeeek" Izuku squeaked and hugged Nezu, "Nezu-san, you're a genius!! I couldn't even think about it!!"

The Chimera laughed, though a little uncomfortable due to the sudden contact, "I'm your mentor for a reason, Izuku-kun"

"Remember, you'll have a window of only a second after we remove his cuffs. Make sure you take the opportunity before he tries to use his quirk." Midnight instructed the purple haired teen as they entered the room.

Shinsou nodded and took a deep breath. He stood in front of the brunette and clenched his fists in nervousness before sending a nod to the Ravenette.

"Oi, what's your connection with the League?"

"...."

"Speak up or I'll make you!"

"Ehh?" The brunette looked up with a mocking smile, "you're going to-" Midnight pressed the small button on the remote and the cuffs loosened "-make me? Who do y-"

"YESS!!" Izuku exclaimed as the brunette's eyes became dazed. "Amazing, Shinsou-kun!"

The purplette smiled at the compliment. Tsukauchi held out photos of a few villains and looked at Shinsou. Midnight had told him what to ask before they entered the room.

"Which one of them leaked the information about the USJ to the league?"

The brunette's hand mechanically rose and pointed to a blonde woman. Tsukauchi sighed in relief while Izuku scribbled something on a piece of paper and gave it to Shinsou.

"Which one of these is your quirk?" The purple haired boy asked, showing the paper. On it were two options: Enhanced hearing and Manipulation. The brunette pointed to the latter.

"How did you get the information from UA? Don't even try to lie" Tsukauchi demanded.

The woman clenched her eyes shut and hiccuped while crying, "I d-did no such t-thing!"

"You can't pretend anymore" Aizawa said calmly, "your friend in the force revealed everything about you"

"Suzuki?! H-" the blonde's eyes widened when she realised she practically gave herself away.

Hawks smirked and leaned back into his chair, "Yes. That guy. Pretty stubborn if you ask me. Tch, cost him a lot"

"W-what did you do?"

"Oh, nothing much" the winged hero shrugged, "just made him knock on death's door.. twice"

"So if you don't want to same fate, you'll have to answer" Aizawa added with a creepy grin.

"Y-you guys are h-heroes! How c-could you do t-that?!"

Tsukauchi smiled at her nervousness, "What can we say, miss, desperate times call for desperate measures"

The woman froze in utter horror while the men patted themselves on the back for their acting skills.

"Now, shall we begin?"
---------------

"So her quirk is called insight, huh?" Midnight mumbled, "and she stole the information from Majima's memories when he was out to check the USJ systems. Tch, what a pain. Anyway, at least we got to know how the information was leaked"

"Not only that!" Izuku exclaimed, "we even got the location of the base!"

(A/N: Sorry for the late update. I'm not feeling well from the past 2 days. The next chapter will be a little late, maybe 2 days. Hope you enjoy this! <3)
