Bakerō, a yōkai soul inhabiting electronic devices, appears primarily in the 2007 anime adaptation. Initially bound to a wooden staff topped with a large eyeball under Hyakume’s control, he later shifts to possessing a red and black flip phone featuring a square screen, octagonal keypad, and a square cover hole that perpetually reveals his signature green iris across all occupied devices. Following the staff’s destruction, his soul drifts through various objects before anchoring itself to the flip phone. Bakerō wields the power to possess objects and manipulate his host’s functions, such as initiating calls via a rotary-style keypad. He emerges in episode 55, *The Curse of Hyakume*, executing actions influenced by Hyakume’s schemes. Documented sources note no additional appearances in films, OVAs, or spin-offs.
