Tsuki Kageyama

Monster Hero

Quirk: Outraging Darkness

Her quirk was created in the lab that the Doctor for All for One runs, and that doctor took quirk genes from Tokoyami Fumikage whos quirk is Dark Shadow. He messed with the genes and made it a whole new quirk. The quirk that she was given makes her an uncontrollable monster of darkness. When in complete darkness her quirk can activate on its own, causing destruction everywhere. Only when a certain amount of light is cast will the quirk turn off. And it is stronger in darkness. When freed she went to UA where she learned to control it and maintain a shape which is a cat-like beast.
