Bu-chan is a shy and kind-hearted character belonging to an unusual family unit. Interactions within this family frequently generate slapstick comedy and heartwarming moments. The character functions as a promotional mascot for the Yabaton restaurant chain, which specializes in Nagoya's regional misokatsu cuisine. This association situates Bu-chan within the commercial environment of the Osu shopping district, where Yabaton's main shop operates directly beneath a towering mascot structure.
