Seto, Sun

瀬戸燦

Sun is the daughter of Seto Gozaburo, the boss of the mermaid Yakuza Seto Group. She firmly believes in the chivalrous spirit of mermaids and is devoted to her role as Nagasumi's wife. Since she is not yet an adult, Sun cannot fully maintain her human form; her legs revert to a tail whenever she comes into contact with water.
Sun is well known at her school for her figure, tall height, and model-like appearance.
