Хосороґі Міябі

Miyabi Hosorogi is a spirit possessing Misaki Sakimiya's mechanical pencil as per a pact with the Corpse God. He currently works as a 'gimmick' in the Corpse God's fortune-telling business, acting as an autonomous pencil in order to convince clients of the Corpse God's legitimacy.

While alive, Hosorogi was at one point Chief of Police and an Internal Affairs inspector investigating a certain symbol alongside Tsubaki Iwanome. He was murdered before he could see his case through, and his last lingering attachment to the world is his desire to see the case entrusted to Iwanome.
