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!

The very essence of reality crumbled around their decaying corpses, their divine auras still gnawing away at existence itself.Atop the mountain of annihilated deities, a towering figure stirred.A shadowed colossus, muscles harder than celestial ore, veins pulsating with endless power. His crimson eyes burned through the darkness as he lifted a grotesque, pulsating sphere of dark flesh to his lips.With a grin, he bit down.The sphere twitched, still alive—still screaming—before it was reduced to nothing but nutrients.Wuji exhaled, his breath alone shaking the void.“Annoying little pests... at least they had some use.”
