Deku is a Malvakian from Vampire: The Masquerade. Dabi and Shigaraki aren't big fans.

Malkavian Deku

Dabi wasn't expecting to meet anyone he'd feel comfortable around when joining a group called the League of Villains, but that one kid...he made Dabi feel distinctly uncomfortable.

He thought Toga would be the only bat-shit crazy teenager he'd see in the League, but Malachi was even further in loon-town than her. Always with this dazed look in his eyes. Even when he was talking to you, it was as if he was listening to a hundred other conversations at the same time.

Speaking of, the kid couldn't talk without sounding like someone took a normal sentence and threw it into a blender with a bunch of bullshit. Refused to call anyone by the name they gave, either. The boy took one look at Dabi and dubbed him Agni.

It sounded vaguely familiar, so Dabi looked it up. Other than the name of some minor hero from forty odd years ago, it was the name of the Hindu God of fire. Fair enough, Dabi liked to think his flames were pretty hot.

(The part where Agni was also the oldest son of some god called Brahma in one version had Dabi closing the tab on his phone and resolving to keep a closer eye on the kid.)

Malachi and Toga seemed to get along well enough. She tried to stab him once, and he called her the Rebel Queen of the Hungry Bath. Whatever the hell that meant. It made Toga coo, though, and that made Dabi wish his eardrums had been irreparably burned, too.

Rounding off the Whackjob Trio was Twice. Or 'Janus', as Malachi dubbed him. Out of the three, Dabi found the man the most tolerable. Sure, the contradictory outbursts made it hard to tell if you were ever on the same page, but he was amusing enough. At least his ramblings made sense.

But whatever. He wasn't here to get along with people.

No. He had a plan to stick to. And one day, if he stuck with the League, he might just get to act on it.

"Oi, Malachi, grab a controller, I need a second player for this part," Shigaraki said, sneering at the screen. The man couldn't advance on this one particular segment of his game without someone else joining in halfway through. He'd been seconds away from a tantrum after everyone refused, but fortunately for the integrity of Kurogiri's bar stools, Malachi entered the room.

"The author of my intent has bestowed on me the powers of gaming," Malachi said, the words tumbling out of his lips as usual. "I shall join you in this futile escapade of escapism."

"Just shut up and grab the damn controller!"

"Reveal yourself face up, and acquire a beast of ritual."

"SHUT THE FUCK UP!"

Every day, Shigaraki regretted letting Malachi join. The brat made zero sense on a good day, and his vacant staring made Shigaraki want to grab his face until he could fit down a vacuum nozzle.

The boy's gaming skills, and willingness to play with him was one of the very few benefits Shigaraki found by having him in the League. As for the other…

"Oi, brat, wh— HEAL ME! — where is the UA first year training camp going to be?"

Malachi remained silent for a while, his fingers blurring across his controller. "The one day location of the harbinger's of a new age?"

"Yeah, sure, whatever."

Malchi giggled. It probably freaked most people out, but it just made Shigaraki's neck itch. "The mewling kittens shall make their strides in the woodland of their elders."

Fucking… "In Japanese?"

"Japanese, English, in which does your perception engage?"

Shigaraki's pinkies twitched towards his controller. "Speak clearly, damn it!"

"My words are as transparent as the flesh on your bones. In the forest of the big cats, wild, and young in heart if not body, the fledglings will learn to be more."

"For the last time, SPEAK FUCKING JA—"

"Ah, I see. So that is where they shall be."

Shigaraki dropped his controller. "S-Sensei?!" Shigaraki looked to the screen where his teacher communicated with him from afar. He hadn't realised Sensei had been listening.

"You must learn to be more patient, Tomura. Malachi's meaning is clear, if you take the time to examine his words. You mean to say that they will be with the Wild Wild Pussycats, do you not, Malachi?"

"Patience born of time spent is easily applied. You speak truth, man behind the curtain. The boy of the igniting applause shall be there, as shall the current musketeer."

"Hmm, I see. I must say, Malachi, your quirk is quite interesting. I've never seen a foresight quirk that affected someone quite as much as yours."

Malachi giggled. "Your record collection shall forever lack Iron Man, I think?"

A deep chuckle came from the speakers. "Indeed. I quite like my mind as it is. Tomura."

"Yes, Sensei?"

"You now know what you need for your plan. Your decision to allow Malachi into the League has paid off. Now, show me what you can do with the resources you have gathered."

"Of course, Sensei."

After a moment, it was apparent that All For One had left the conversation. Shigaraki examined Malachi out of the corner of his eye.

He'd have to pay more attention to what Malachi had to say. One day, he would reach a point where he no longer needed his Sensei to translate for him. But for now—

"Your remaining life is falling out."

"Wh—" He glanced at the screen. "SHIT! HEAL ME!"

"My blue has landed on the ground."

"DRINK A POTION THEN!"

"I shall attend the digital service with a heart of raindrops."

"FOR FU—"
