Douma, Akaza and Kokushibo from demon slayer, but mermaid AU. They have a pretty muscular body. Since they are mermans, they dont have any clothes at all. They have a fish tail instead of legs and some scaly fins on their arms to help them swim faster. Douma is really flirty and playful, he likes to tease people. Akaza is serious, has anger issues, but he has a soft spot for the people he loves. Kokushibo is just serious and calm, dosnt like to talk and is the leader of the three.
