Crow belongs to the G-Boys, a prominent youth gang in Ikebukuro, sporting brown hair with tied-back bangs and black eyes. His typical outfit features a light blue and white jacket over a blue shirt, black jeans, and shoes. Beyond gang life, Crow channels fervent enthusiasm into cinema as a self-proclaimed movie fan. Within the G-Boys, he maintains friendly ties with Makoto Majima, frequently acting as an informant who relays critical updates about violent attacks targeting fellow members.

Amid escalating internal strife, Crow sides with Hiroto’s faction against leader Takashi Ando. His involvement deepens upon receiving Makoto’s intelligence that "Shadow"—mistaken for a rival gang—is actually an individual assassin hired by Mars Enterprises. Crow urgently passes this revelation to Hiroto.

Operating from the back room of a video rental store—a strategic gang hub—Crow witnesses Makoto’s assault by a rabbit-masked assailant identified as Yamamoto. He persists in faction-conflict mediation efforts, yet staunchly backs Hiroto’s side during near-violent clashes at Ikebukuro’s three-way crossroads.
