Kanechika Umehara operates as a contracted monk of the Kōgon Sect, renowned for his mastery in commanding Shikabane Hime and instructing fellow priests. His capacity to sustain multiple Shikabane Hime at once sets him apart, enabled by rare energy reserves that circumvent the usual lethal toll. Initially bound to the stern Shikabane Hime Touma—who later falls dormant—he shifts allegiance to Flesh Backbone, an anime-exclusive partner marked by otaku quirks and a lighthearted personality. This contrast underscores his unorthodox partnership strategies.

Though a respected mentor, he avoids sect factionalism, preferring isolation. His reputation intertwines with eccentric habits, such as collecting moe-themed figurines and covertly observing Shikabane Hime in vulnerable states, like during baths. These antics invite Touma’s rebukes but amuse or are tolerated by Flesh Backbone.

In combat, he wields the Shinken Ascala Sword—a blade only he can access—alongside a Shakujō staff, blending close-quarters prowess with strategic insight into Shikabane tactics. This expertise cements his value to the sect.

While official media explores little of his past or growth, his interactions emphasize the sect's internal tensions between ascetic rigor and earthly indulgence, particularly through his humorously fraught rapport with Flesh Backbone.
