Bio: When Fumikage was very young, before his Dark Shadow quirk manifested, a villain kidnapped Fumikage and held him near an abandoned factory. To save his son from the villain, Idoku transformed into his Black Death form in combat. His anger and the surrounding pollution caused him to lose control of his quirk and killed the villain. Idoku's last words before being permanently bound as Black Death was for his son to run away.

After developing his quirk, Fumikage aim to become a pro hero to prove that he can master this dangerous quirk. Part of him also wish to understand the quirk in an attempt to free his father from it, if he's still alive. Fumikage does not speak of his father in fear of having the same fate as him.
