“When you think everything is going well, the world will flip you the middle finger.”__I had a fantastic life: a loving family, amazing friends, a stable job... I had it all.But that wasn’t everything—I was also a writer. Writing was my passion, and my novel *'The Land of Survival'* had achieved remarkable success...Little did I know back then that it would become the very reason my life would be turned upside down. I was reborn inside my own novel, and to make things worse... inside the body of the utterly despised villain, *'Fray.'*That pathetic villain who dies right at the start. If the novel had 100 possible outcomes, he’d die in 99 of them... and I’m not exaggerating.But who cares about that? I don’t want this life... I already had everything... Save me the cliché of second chances... because one life is enough for me.Screw this world, and screw the son of a bitch who brought me here , I’ll find a way back to my world... to my life... no matter what it takes.

A man reincarnates in the body of a boy who suffered a tragedy, only to realize that he is in the world of My Hero Academia. What's even stranger is that his quirk seems to have the abilities of Nen and Haki.
