Konchi, a 400-year-old kitsune Seirei, serves as one of Tamamura Tamao’s guardian spirits alongside Ponchi, a tanuki of equal age. Both spirits, enshrined in the Asakura Family’s ascetic hall, are notorious for their mischief—peeping, casting minor curses, and disruptive antics. Initially resisting attire, they reluctantly adopted cloth diapers after reprimands from Matamune and Anna Kyoyama, whose stern presence commands their wary respect.

Konchi’s combat role emerges through integration into Tamao’s Oversoul techniques. In the weapon-type O.S. "Cupid," Konchi fuses with a planchette to create a heart-shaped bow firing precision-guided Love Strike arrows. The defensive O.S. "Angel" pairs Ponchi’s enlarged scrotum—transformed into a shield—with offensive trapping capabilities, underscoring their tactical versatility amid chaotic behavior.

Spin-offs like *The Funbari Onsen Saga* depict Konchi and Ponchi in kimonos instead of diapers, with Konchi sporting long black hair and Ponchi affectively puffing a pipe. Their names stem from Japanese sounds: "kon" mirrors a fox’s bark, while "pon" evokes a tanuki’s drumming belly. Konchi indulges in voyeurism, contrasting Ponchi’s penchant for pilfering undergarments.

Though their roles occasionally expand to reconnaissance or minor missions in official narratives, their core as comedic provocateurs persists. Their unsealed status reflects a calculated tolerance for their antics, balancing irreverence with utility in Tamao’s shamanic endeavors.
