Haramase Tamer no Isekai Gakuen Musou ~Kyonyuu Mesu-tachi o Kozukuri Tamer Shite Saikyou no Harem Gundan o Tsukutte Nariagaru!~

The protagonist attends an academy for training adventurers, but he’s stuck with the underappreciated ability of a Tamer. On top of that, his overwhelming libido makes him a pariah among women, leaving him frustrated and restless. One day, after fellow adventures trick him into acting as bait and nearly dying, he stumbles upon a treasure meant exclusively for Tamers. This treasure grants him a cheat-like ability to tame any living being—humans, elves, and more. And so begins his new life: taming, impregnating, and reducing the world’s most powerful, noble, pure heroines with potent magical powers into his personal playthings. Every day becomes a wild, unrestrained indulgence in depravity!
