   Summary

   What if Eijirou Kirishima had a much darker past then what we've been told about? What if his guidelines for what is moral and just were a bit more skewed? What happens if any and all control he has is tested by a certain angry blond?

   He hasn't had an easy life in the time leading to his UA enrollment. Sure it wasn't always rough but it sure wasn't easy. He fought tooth and nail to get to where he is. Overcame every obstacle that was thrown at him in order to do his best. This is the story how he was able to over come his anger, depression, and borderline insanity. All of it being made possible by the blond that drives up every possible wall.
