Kyokanchin holds the position of chief manager at Skull Lease’s Northern Ostendel Branch and operates as part of the Clean Aku trio. Sporting two prominent buck teeth and beady eyes, his design retains a classic aesthetic distinct from others in the series. He communicates with a blend of casual politeness, though his tone sharpens to authoritative commands when directing subordinates—a habit rooted in his military past. This discipline informs his leadership, hinting at an authoritarian approach if granted unchecked control over Skull Lease.

He shares a residential complex with colleague Kosuinen but routinely disregards punctuality. While fostering amicable ties with both Mun-Mun and Kosuinen, frequently mediating their clashes, he subtly aligns with whichever ally is present during disagreements. His personal ambitions lean toward wrestling rather than management, with sporadic, unpredictable outbursts unnerving his superiors. These superiors occasionally sabotage him, exemplified during a mission against Tamashiro, a rival agent from Skull Lease’s Western Branch.

A subplot threads his unrequited affection for Min-Min, granddaughter of Con Cordo. In episode 29, her playful remark labeling him "cute"—paired with a wink—ignites a vivid fantasy of marriage and ascension to Skull Lease’s leadership. This infatuation crumbles when Min-Min clarifies her disinterest, inviting mockery from Kosuinen. Subsequently, Kyokanchin exits Skull Lease, accepting a nikuman bun as severance before boarding a train to seek reinvention. Unbeknownst to him, former superiors ride the same train, chasing parallel ambitions.

His narrative arc concludes with this departure, marking his final documented involvement in Skull Lease’s operations. No subsequent appearances or developments are recorded in related media.
