The Bonds of Power

In a world where magical incursions known as dungeons threaten humanity, a select few are marked with classes that grant them extraordinary abilities to combat these threats. At the age of 25, Ethan, along with his twin sister Alice and girlfriend Penny, receive their class marks, revealing their destinies as defenders against the encroaching threat. Ethan's class, however, is anything but ordinary. As a Bond Enchanter (S Rank), he possesses the unique ability to create powerful bonds with others through intimacy, generating essence that enhances his allies' abilities and heals their wounds. This sexual nature of his class sets him on a collision course with societal norms and personal ethics, forcing him to navigate a complex web of relationships and expectations.
