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