The Witches of Adamas manga volume 2 features story and art by Yu Imai.

Satou Yukinari already expels literal diamonds, but his curse is still evolving! He’s been holding back from getting off so long that he’s begun to produce Hottie Pheromones, the effects of which flip his once peaceful school life on its head. A harem of thirsty girls all want a whiff, and before he can escape, it culminates in a buxom teacher ensnaring him in a classroom after school!
