Sacrificed to the Shark Clan

A powerful clan that inherits the blood of sharks meets a sun-tanned man with a unique physique in a fateful encounter!

Avel, son of the Tangata Clan's patriarch, grows increasingly dissatisfied with the Miyaru Clan, which resides on the opposite side of the island. Every year, according to a long-standing and disgusting law, the Tangata Clan presents one young adult to the Miyaru Clan. One day, when he's attacked by a beast, Tukiri of the Miyaru Clan comes to his rescue. Surprised by Tukiri's friendly, kind demeanor, Avel lowers his guard... but the second Tukiri recognizes that Avel is bleeding, his personality flips a switch! He loses his humanity and becomes beastly in a different way, much to Avel's panic. Because for members of the Tangata Clan, thanks to their unique physiques, their first intimate experience determines their gender. If he's taken like a woman, he becomes a woman...! As next in line to become the next patriarch, he fears the consequences, but at the same time, he drowns in waves of pleasure...
