Conchi, a kitsune spirit approximately 400 years old, serves as one of Tamamura Tamao's two Guardian Ghosts alongside Ponchi. Both spirits, now Seirei Class, reside in memorial statues within the Asakura Family's ascetic hall. They exhibit perverted and mischievous behavior, frequently making crude threats involving disrobing or urinating on opponents using Ponchi's oversized anatomy. Despite their nuisance tendencies, they remain unsealed due to their utility in reconnaissance missions—often for voyeuristic purposes—simple divinations, and minor curses. They display cowardice, fleeing powerful spirits like Zenki and Kouki and abandoning Tamao. Their fear extends to Kyōyama Anna, who disciplines them for leering at women's baths, resulting in cloth diapers after confrontations with her and Matamune. They initially resisted clothing but adopted diapers following these encounters.

In combat, Conchi forms the Over Soul "O.S. Cupid" with Tamao, using a planchette as a medium to create a heart-shaped bow and arrow. This weapon guides arrows according to Tamao's desires, executing the "Love Strike" attack. Ponchi's Over Soul "Angel" contrasts by creating a defensive heart-shaped shield with offensive capabilities via scrotal expansion.

Media adaptations diverge: the manga depicts Conchi in Tamao's initial Over Soul appearance and battles against the Hana-Gumi and Anatel Pokki, demonstrating unexpected bravery. The 2001 anime limits their combat to one incident against Ryu and Manta Oyamada, whom they falsely accuse of causing Yoh's misfortune after lying during a kokkuri divination out of boredom. The 2021 anime retains Ponchi's anatomical traits in its English adaptation, unlike the English manga, which redrew them as a "large belly."

In the sequel *Funbari Onsen Saga*, both spirits exhibit significant development, adopting kimonos and refined traits: Conchi grows long black hair, while Ponchi smokes a pipe. This evolution highlights their shift toward dignified spirits while retaining traces of their original personalities.

Their names derive from Japanese onomatopoeia, with "Kon" mimicking a fox's bark. Inspired by Ren from *The Ren & Stimpy Show*, they embody comedic, animalistic spirits. Conchi's hobbies include voyeurism and a fondness for candy.

Functioning as foils to Mikihisa Asakura's disciplined spirits Imari and Shigaraki, they represent "negative versions" of traditional shamanic companions. Their journey illustrates a gradual transition from chaotic troublemakers to marginally more responsible guardians.
