Now one fateful night changes the course of his life, forced to fight after fight, he shall face his inner demons and his past that comes to haunt him.

A/N: Alternate Reality to Canon, there are far major changes to the canon and this story doesn't focus much on the main characters, canon characters are having involvement in several cases.

Warning: Curse, death, sexual stuff, suicidal, may seem like I'm bashing Issei but there's a specific reason as to why what happens when it goes to him.
