Kai chisaki(overhaul) walks through the streets of Tokyo, staring at his feet with a slight frown. His therapist said that he should 'go outside more', but honestly, he doesn't understand how it can help him.

Someone bumps into him. Normally, kai wouldn't pay attention to this - it's hard not to bump into anybody in such a crowded place as Tokyo. But out of the corner of his eye he sees a hand rummaging through his pocket.

Kai catches the hand on instinct, squeezing it tightly before the pickpocket can blend in with dozens of other people.
