Kikuchiyo is a central character in the anime film KILLTUBE. He is a member of the main trio alongside the protagonist Musashi and the inventor Leonardo. Kikuchiyo is described as a born con man and a smooth-talking, cunning individual. Despite his sly and manipulative qualities, he is also portrayed as a sympathetic figure, acting as a producer-like figure who supports the group's ambitions. His primary motivation, shared with his companions, is to escape the rigid social hierarchy of an alternate 2026 where Japan remains under Edo Shogunate rule. The trio, considered the lowest members of a strict class system, aims to change their status by participating in the duel broadcast platform known as KILLTUBE, a government-run service where combatants fight for wealth, fame, and freedom.

Within the story, Kikuchiyo acts as the group's strategist or manager, leveraging his talents for deception and persuasion to help them navigate the world of deadly livestreamed duels. His key relationships are with his two partners in crime: the wild and untamed Musashi, and the eccentric genius Leonardo. Together, they form a unit of societal outcasts who rise from obscurity to fame through their victories. Information regarding a specific character arc or notable combat abilities for Kikuchiyo is not detailed in available sources, though his role as a con artist suggests his primary strengths lie in cunning and resourcefulness rather than pure physical prowess.
