"Hibiki" is his code name as an Oni; his real name is "Hitoshi Hidaka." Height: 179cm. Age: 33. Has a sturdy build with a mature, calm sex appeal. Usually wears casual, easy-to-move-in jackets or shirts. Has a frank, aloof, and friendly personality. Due to his composure as an elder, he also has the side of a "reliable adult." However, he is quite dense when it comes to romance. His hobby is training. He occasionally falls into slumps, and at those times, he tries to clear his mind by etching the sounds of nature into his soul. His catchphrase is "I've been training," and he often gives a salute-like greeting (rotating his wrist once with the ring and pinky fingers slightly bent, then flicking it forward) called a "Shu!" He is extremely bad with technology; he uses a notebook to record Makamou encounters and does not own a credit card or a mobile phone (he can use public phones). Regarding mobile phones, he can use the calling function without issue, but he fumbles just trying to open an email. Therefore, to contact him, one must go through Takeshi supporters or acquaintances. He serves as an emergency partner for Nanami, who was in trouble without a drummer. He often listens to Nanami's songs at the Takeshi headquarters. He respects the other participants.
