Hibiya (ヒビヤ) is the eighth member of the Mekakushi Dan. 

Hibiya can be a short-tempered and judgmental guy who he gets easily jealous when his affections for Hiyori Asahina are challenged. His love for Hiyori is so strong that he recorded her voice, took many (secret) photos of her, keeping the most beautiful one in his bus pass, and even made a doll of her–complete with a voice button. Though they were childhood friends, he sees himself as one of her many fans, as she is the most popular girl in his school. He can get embarrassed and flustered easily when said affections are pointed out or when he acts without thinking. In order to visit the city with her, he had to repeatedly beg his father and is only able to go when he says that he intends to attend classes about India that are available only there that summer.

He can be rude to strangers, such as Momo Kisaragi, whom he instantly calls "oba-san" ("aunt" or "old lady") before either is introduced to each other, though in Manga Route 2, Hiyori apologizes for him and says that he doesn't understand manners because he's from the countryside. Despite his often brash attitude, he can be considered at times mature for his age. He also has a talent in cooking, which is unusual for boys his age.

Focusing Eyes: Hibiya's eye ability has the power to perceive objects and details that are far away from an aerial view by focus. Because he gains his powers right before meeting the Mekakushi Dan, he has the least control over his ability and finds it difficult to perform. In the Novel Route and with Shintaro Kisaragi's guidance, he is able to use Focusing Eyes through Momo Kisaragi's phone to locate and communicate with Shintaro's phone, which was in the Kagerou Daze.
