Regressor: Harem Building Lunatic

In his last life, Mizuhara Souta wasted everything. His youth, his chances, the girls who loved him.

Now reborn into his youth, he won’t make the same mistake twice.

To everyone watching, it looks like the start of a normal romcom: a childhood friend walking with him to school, a kind mother fussing over him like family, and a new transfer student bound to stir things up. Cherry blossoms, school trips, festivals. Sweet, wholesome, ordinary.

But Souta remembers his regrets. This time he’ll claim Kotoha, the innocent childhood friend who’s already learning to melt under his touch. He’ll reach for Hikari, her gentle mother hiding forbidden desires. He’ll welcome Hiyori, the late arrival destined to complete the picture.

On the surface, it’s love and laughter. Underneath, it’s oyakodon, obedience, and the purest harem imaginable.
