3rd point of view: 

Detective Naomasa Tsukauchi leaned back in his chair, exhaustion weighing heavily on his shoulders. Another day, another mountain of reports, tips, and dead ends in the fight against villains. His truth-telling quirk was a blessing in interrogations, sure, but paperwork? Not so much.

He reached for his mug of coffee—lukewarm, of course—and clicked open his inbox. His eyes skimmed over the usual clutter: spam, official memos, and a few flagged tips from informants. But one email caught his attention immediately.

Sender: [email protected]
Subject: URGENT: Anonymous Vigilante Intel

Tsukauchi froze. His name? As the sender? What kind of sick joke was this?

Frowning, he clicked it open.

Dear Detective Tsukauchi,

First off, don't freak out.

Too late, he thought.

Yes, this email is coming from your account, but before you jump to conclusions about hackers or villains, let me clarify: it's me Sivax.

Tsukauchi's frown deepened.Sivax. The name stirred something in the back of his mind—vaguely familiar, like a whisper from an old case file...or helper. He kept reading.

I'm the vigilante who's been sending you those anonymous tips. You're welcome.

Tsukauchi : .... You're welcome?

Tsukauchi muttered, raising an eyebrow.

Now, let's cut to the chase. I'm in deep trouble. Like, seriously deep. The kind of trouble that ends with explosions, interrogations, and, honestly, probably therapy. For now, though, we can focus on the explosions part.

Tsukauchi's mouth twitched. Explosions and therapy? This person got a sense of humor.

Here's the deal: I've been stuck in a villain group's hideout for way too long. They think I'm some kind of prodigy or whatever. (Spoiler alert: I'm not.) I've been playing along because, well, I'd rather not die today.

He sat up straighter, the humor of the email fading as the gravity of the situation began to sink in.

But things are escalating. Fast.

You need to send help. Like, yesterday. But—and this is important—I'm begging you, please don't send someone like All Might. He's great at punching villains, sure, but stealth? Not his strong suit.

Tsukauchi chuckled under his breath. 

Tsukauchi: That's... not wrong.

Here's my wishlist of heroes:

Hawks: Pretty sure he can sneak in and out without blowing my cover.Miruko: High-energy and terrifying in the best way.Eraserhead: If anyone gets how to handle this quietly, it's him.Midnight or Present Mic: Because they seem like they'd at least keep things interesting.Endeavor: Not subtle, but scary enough to make the villains reconsider their life choices.

Just... not All Might. I cannot stress this enough. The man has the subtlety of a meteor.

Tsukauchi couldn't help it—he burst out laughing. The sudden noise drew a few confused glances from nearby officers, but he waved them off, focusing back on the email.

The villains I'm with aren't exactly brainiacs, but they're connected to something bigger. I don't have all the details yet, but trust me, you're going to want this intel.

Here's the current situation:

Location: Naruhata district, in a converted library.Threat level: Low, if we're talking competence. High, if we're talking sheer stupidity.My quirk: Not super relevant, but in case it helps, I'm deaf. If anyone on your team knows sign language, that'd be a bonus.

I know this is probably the weirdest email you've ever received. (And let's be real, you're a cop; you've probably seen some weird stuff.) But I'm out of options here.

Help me out, and I'll spill every ounce of information I've gathered. I just need a way out.

Sincerely,
Sivax

By the time he finished reading, Tsukauchi was already running through the possibilities in his head. A vigilante using a truth-teller's account to send a plea for help? Ballsy. Risky. And probably one of the most genuine cries for help he'd seen in years.

He quickly opened his database and searched for "Sivax" The file that popped up was thin—too thin. A missing child's report from over a decade ago was the very first thing Sivax had given them as information. It was the very same amount of how much information Sivax gave them about said child Izuku Midoriya that there was the note of a possible chance that the kid was the vigilante. 

A brief mention of a quirkless diagnosis. No known connections to any hero work or vigilante activity.

So how did a quirkless kid end up hacking into his email and embedding himself in a villain group?

Leaning back in his chair, Tsukauchi rubbed his temples. The kid's wishlist of heroes was another layer of intrigue. It wasn't just a cry for help—it was a calculated move. This isn't just some scared kid.

He flagged the email and forwarded it to his personal device. Then, he leaned forward, pulling up the necessary paperwork to authorize a covert investigation into the Naruhata library.

Tsukauchi : Midoriya, huh?......Let's see if you truly are Sivax.... and that kid from years ago...."

Meanwhile...

Back at the library, Izuku leaned against a bookshelf, nervously tapping his fingers on its edge. He hadn't heard back yet, but honestly, what had he expected? That Tsukauchi would jump out of a helicopter within five minutes?

No,.... That's not how law enforcement works.

Still, the waiting was killing him. He glanced at the group of villains lounging nearby. Idiot #3 was snoring. Idiot #5 was flipping through a magazine upside down. Idiot #1 was, yet again, accusing someone of stealing his coffee.

Yep, Izuku thought with a dry smirk. Competence is definitely not the vibe here.

All he could do now was wait—and hope his message reached the right people.
