Story
Ken Komatsubara (5th grade) transfers to an elementary school in Ginza. The Ministry of Foreign Affairs issues a "Caution Advisory" to him without giving any explanation. His presence sends ripples through the police, local gangs, and even private military companies based overseas. In a town lined with luxury brand shops, the fighting abilities of a boy who seems to have been "born out of violence" are unleashed!
