What has he become

As a child, Tenko Shimura lived in a household with his parents, maternal grandparents, and a sister named Hana. He had a fascination with heroes, but this was strictly forbidden by his father, Kotaro, who harbored a deep hatred for heroes. This animosity stemmed from his mother, Nana Shimura (a hero and former wielder of One For All), who he felt abandoned their family. Kotaro's aversion to heroes led him to be physically and emotionally abusive toward Tenko, often punishing him harshly for his interest in them. Tenko's other family members, while sympathetic, were too afraid to intervene, which led Tenko to feel a growing resentment and sense of betrayal. Tenko's childhood was marked by intense trauma. Yet he did not know the monster he'd soon become.
