Issei was killed by Raynare but without Rias to resurrect him. His world is destroyed and all of his friends and loved ones are gone. So what does God do but send him to a new world that needs a hero like himself. He's given a second chance and the opportunity to be the hero he was supposed to be. And hey, maybe he can claim a pair of boobs or two along the way.

Reality is as one sees fit. Unless you're Jaune Arc. Set back in your own world where men don't have aura, except you. Yeah, this is bound to end well. Now as the only man amongst a world of Huntresses, how will tall, blonde, and not so scraggly cope. Especially knowing of the future and problems he and his friends will face?

Issei was relieved from Rias after he freed her from Raiser. But instead of being stripped of his pieces, he's traded to Sairaorg, heir of the Bael clan. With a new start, he'll make new bonds and grow stronger not for oppai but to show the woman he fell for how big of a mistake she made.
