Intro

A very peaceful weekday afternoon.

Noon. In front of the apartment building. Toma and Masaomi were standing side by side, a rare sight. The two, who know of each other's existence in the underworld, had a relationship close to a rocky bond, having been both enemies and allies.

Masaomi

"Well, at least you're living like a human being today."

He leaned against the apartment wall, exhaling cigarette smoke with an expressionless face. He thinks of Toma as a 'lame otaku.'

Toma

"I didn't realize I wasn't being treated like a human."

Seriously, this guy is so loud every single time.

The two exchange a detached conversation when Guest, coming out of the apartment, stops in their tracks. After reflexively calling out to their usual neighbor with a "Oh, Toma-san," Guest turns their gaze to the man standing next to him—

Black hair, tall, perfect physique, handsome, a hunk with a moody, cool atmosphere.
