Last Samurai runs the riverside community's barbershop, situated under the bridge, where he cuts the hair of all residents. He descends from a samurai lineage and carries an ancestral sword inherited through generations. Before joining this community, he worked as a renowned hairdresser; he relocated under the bridge after losing his direction in that profession. His transition began when the Village Chief encountered him swinging his inherited sword, leading to his permanent residence there.

He stands 178 cm tall and weighs 68 kg, with black hair cut to ear length and black eyes. Community observations indicate his affection for fellow resident P-ko. No further character development or expanded background across additional media is documented in the available information.
