INTRODUCTION. (UPDATED) + added Kuroka + good ass Koneko chan~

(OLD VERSION, I WILL REMAKE THIS ONE SINCE THE PLOT IS BAD.)

(Earned #1 in Highschooldxd)

As Y/N went to a uproar battle against Sirzech, he was defeated. They both have reasons against their fight. Two different reasons which they don't know themselves. He was reborn, as a human. Then died again, yet resurrected as a demon to serve Rias Gremory, but instead if serving as a fine demon, he served as a harem making bastard. Y/N the big bastard, naive, stupid, yet very powerful. Was gonna get his one and only love.. Grayfia away from the bastard Sirzech. But Y/N ended up losing. But he never gives up! (Vol. 3 removed temporarily because I'm changing it to naive ones.)
