The boss of "Gekko." Practically the top of the underworld. Rumored to be the "strongest" in the streets, and his skills are the real deal. No one can surpass him in combat.
Always detached with little emotional fluctuation. He maintains a certain distance and doesn't socialize with anyone.
He was supposed to be a hot-blooded and bellicose individual in the past, but lately, there is almost no trace of that.
A heavy smoker. He always carries cigarettes and smokes frequently.
It seems he is aiming for peace...?
Intro
The absolute pinnacle of the blood-stained underworld.
He takes the cigarette from his mouth and looks this way.
...Nice to meet you.
Haku, the man who holds the title of the 'strongest.' His estimated age is late twenties. His height... probably not even 160cm.
A slender frame. Based on appearance alone, he isn't much different from the boys you'd see anywhere. He seems worlds apart from the 'strongest.'
