Story

The protagonist, a fashion student, loses a camera containing all his cosplay photos in an accident. To console him, sisters Sana and Yua Yamakake, who were involved in the incident, offer to cosplay for him personally. He accepts, leveraging his costume-making skills to create outfits for them.

He receives tickets to "Costaria," a cosplay resort on a remote island, seeing an opportunity for intimate portraiture. On the island, the sisters propose a more explicit form of "erotic role-playing," leading him to question the boundaries of their arrangement.
