I, Hyoudou Issei, am a 2nd Year High school student and my age is equal to the number of years I haven't had a girlfriend. And, someone like me got a girlfriend! I'm sorry buddies, I will walk the path of becoming an adult before you guys! --That's how it was supposed to be, but why did I get killed by my girlfriend!?

I still haven't done anything yet! Are there no Gods in this World!?

And, the person who saved me is the most beautiful girl in my school, Rias Gremory-senpai. I learned the shocking truth from her who isn't a God but a Devil. "You have reincarnated as a Devil! Work for me!"

Lured by Senpai's breasts and treats, my life as a reincarnated Devil began.

So the "Academy×Love Comedy×Battle Fantasy” starts here with just aggressive and worldly desires!
