Trigger

 —So, let me get this straight. Oni not only stopped a drug deal, but it was of Trigger. The drug the police thought had been off the market for years, revealing a hole operation that you don't know how many years has been working. — Eraserhead deadpanned from across his desk.

—Yes. The interrogation of Takami Anki, alias Cobra, was vital for the ordeal. Takami and some of his followers were awaiting in one of the abandoned warehouses near the port. However, Takami has ordered another group, who Takami has identified already, to attack the ship with the Trigger. Their job was to hit fast, grab some of the drug and run. The plan worked, and the sellers arrived to the warehouse with four fifth of the Trigger. They planned to buy only the rest or if stubborn kill them all and pay nothing. Oni intervened just when things started to get heated, put them all in an illusion and set fire to the drugs— explained Naomasa while rubbing his eyes.

—And this Takami guy told you all of this?— asked Eraserhead, skeptical. Naomasa did not fault him, it was rare for a gang member to give any kind of information. They knew that their families would be targeted should their actions be known, or when they were freed from jail a fate worse than death would await them.

—He did, and I confirm it with my quirk. I don't know what Oni did to him, but he confessed everything, even without the plea deal.— affirmed Naomasa.

Naomasa winced slightly, remembering the state Oni had left Takami Anki. Takami was the second in command and a member of the Kurotora, a gang with connections to drug trafficking. What the police did not know was that it expanded to Trigger a few years ago.

Takami had spilled the beans faster than Naomasa could ask him. He was also the only one who had any interaction with Oni. The rest only remember a sound above their heads and red eyes.

—Takami also inform us that they were not the only ones who trafficked with Trigger, it seems that the police will have to open a new investigation on Trigger.— Naomasa was already having a headache just at the thought of his superior's rant when they found out about the Trigger.

— But, most important was that Takami talked to Oni.— that made Eraserhead shift in his chair, sitting more straightly.

Takami had been inches from Oni's face.

—He talked to him?— said Eraserhead, surprised. No one had had any conversation with Oni. He always hit fast and vanished faster. The only thing he said was a variation of 'call the police'.—Why?

—According to Takami, he awoke from Oni's quirk and found him bent above him while he was grabbed from the hair. Then Oni proceed to ask him questions about the Trigger. It seems that Oni did not know what was in the vials, decided Takami knew something and interrogate him. —Naomasa sighed, knowing what came next —He smashed Takami's head to the ground when the latter tried to evade a question or lied. Then he was put into an illusion again for an unknown amount of time, Oni woke him up to call the police and after Takami did, he knocked him out with a punch in the face. Takami has a very broken nose and cracks in his cranium.

—But although his aggression is worrying, it is not what alarm me. As stated by Takami, Oni took one vial of Trigger with him— Naomasa said worrily.

—You think he may use it?— asked Erasehead seriously.

—I do not think he will, but if he encounters a bad situation he might be pushed to use it. Oni is not an adult, am entire dose could kill him.

—What do you want me to do Tsukauchi, I have not made contact yet with Oni, let alone talk to him about the dangers of Trigger. Do you have any new information about that?

Eraserhead was right, of course, but that did not stop Naomasa from worrying.

—His quirk is an illusion quirk, it makes his eyes read when he uses it. Right?— Ereserhead only grunted.

—Well not only are they red, but they have a pattern, these are the drawings Takami made. It's a triple tomoe circling around the pupil. And that is not all, he may have some kind of incendiary bomb. All the vials of drug were incinerated at the same time in a large radius, as we saw by the burns on the floor. That can only be a quirk or a bomb.

—Are you kidding?! — said Eraserhead with disbelief all over his face.

—You know I don't joke at work— was his only response.

—So either he is not alone or he has bombs. Great a child-vigilante with bombes, what's next, does he also have guns?— Eraserhead sighed, look at the ceiling and whispered. — Problem child.

(Unknown to Eraserhead and the Detective, Obito does as a matter of fact have guns. Unfortunately, he does not know how to use them proficiently, nor does he have a sensei to teach him. So until he got one, he will stay with the familiar shuriken. Not that he cares, at his peak Obito was faster than a bullet and with Kamui he would eventually have nothing to fear.)

—I don't know, but this could be the key to encounter Oni.— Naomasa said to Eraserhead.

—How? Do you believe he is going to start hunting Trigger?— Eraserhead was still looking at the ceiling.

—It's possible. And anyway that is more than what we have now. You can't just hope to meet him in patrol.

—Okay, pull me in the Trigger investigation too?— sighed Eraserhead, before standing up and leaving his office.

«One problem at a time. Now, how to tell your superior that a vigilante has surpassed the entire police station.» Sometimes Naomasa hated his job.
