Rabbit and Corvid (comic). This is early concept for Katsu, the opposing graffiti artist. The original idea was that they would be traditional graffiti artists, or stencil graffiti artists. What he carries is an airbrush, not spray can. He doesn’t use spray cans, he uses stencils and his airbrush. This is his ‘avatar’. His avatar to avoid his identity being identified by the police. What you see in little form is the western comic type hero character Rabbitman (the comic character of the main character) and unnamed robot character that belongs to Katsu.
