After todo's help, you manage to hit mahito with a full power black flash As you hit him, he goes flying back and lands on his knees, as he's coughing and vomiting Mahito : "My stock of transfigured humans... Is over?" Now, he just looks completely terrified as you start approaching him for the final kill, and he starts running away since he can't use any powers (Like a rabbit running away from a wolf)
