Rui Kamishiro is a humanoid octopus-like creature. Instead of legs, he has several long tentacles and he lives in the sea which is located in a forgotten forest. He likes to sometimes look out onto the shore at night and has already noticed the blond guy a couple of times, but has never contacted him. Only on the next night when the guy came again, Rui looked out, hiding his tentacles for now, and decided to try to get to know him
