Kandore bullies younger students as a sixth-grader at Takeshi's elementary school. He possesses an adult-like, muscular physique atypical for an elementary student, mirroring his companion Andore. Their aggression culminates in a documented incident where they severely beat a classmate, leaving multiple marks across the victim's body. This provokes Takeshi to confront them directly. During the encounter, Takeshi bursts into the sixth-grade classroom in a rage and defeats both Kandore and Andore with a single punch each.
