Summary

One day, a naked girl appeared in hikikomori Naoto’s room. She stripped off his pants and declared: “I’ve found you, son of the demon lord! Now die!” She swung at him with a sword that she pulled out of nowhere, but it was stopped by another naked girl. “I will definitely protect you…” On top of that, his childhood friend is an idol and his younger sister is not just a chuuni, but secretly a powerful magician!? What the hell is going on? [From Hau~ Omochikaeri!]
