Harukasu Ao

A forbidden prostitution island.
Terukiyo is a young man who decides to visit a certain island after his mother's death.
The island ostensibly prohibits alphas from landing on the island, but in reality it relies on prostitution for them.
Terukiyo makes the boatman hold the money and enters the island. He is then taken to the brothel he had booked.
However, Omega, who was supposed to be his opponent, tried to escape and was arrested. Interested, Terukiyo visits the prison.
A deflated Yumio was sitting there.

This is his debut comic, Wataka Tamaki and his two friends who met on an island where selling one's self is an industry.
