A boy who tried "Urban Legend of the Doppelganger" in the form of dating a friend and gained a special ability. After meeting the protagonist by chance and helping him and Shirasaki out of the blue, he is pushed around by both of them. He has high communication skills, can get along with even the older Sakakura, and is straightforward and unwavering. Although he is a cheerful, single-minded idiot, he seems to have his own thoughts about his uncertain future and his mother's remarriage. [Translated from offiical website]
