Kobayashi is a junior high schooler who finds his everyday routine utterly dull and uninspiring. Everything changed when he was unexpectedly drawn into a gruesome case involving the dismemberment of a teacher—and even became a suspect himself. Rather than being traumatized, he discovered a thrilling fascination with detective work through the ordeal. He went on to become the right-hand man of the brilliant detective Akechi and joined the Boy Detectives Club. Known for his razor-sharp logic and near-total lack of empathy, he is also frequently mistaken for a girl due to his androgynous, delicate features.
