Legend of the Mermaid (CV: Yuusei Noki)

Rex (bottom) is a 300 year-old mermaid prince who's very timid.
When merfolk turn 300, they finally come of age. Since time immemorial, the coming of age ceremony has involved a great orgy, after which the merperson is considered a full, adult member of the community.

But Rex is a bit scared of the "orgy" part -- after all, he doesn't really know what it is. So he fled to the human world. There he meets a young man named Satoru (top), who was deeply concerned for him. Though the shocking of meeting a real merman took some time to fade, Satoru was eventually won over by the creature's beautiful features... and in turn, Rex starts to fall for Satoru and his kindness...
