I

Io was a young man who lived a peaceful life on the shores of San Félix Island in Chile. He spent his entire life there, enjoying the sea and the marine creatures he loved so much. During that time, he helped his father, who worked on a fishing boat. However, due to his great talent and intelligence, he was selected to attend a school in the city of Santiago. Before leaving, his father expressed his sadness, to which Io assured him that he would return during the holidays. In the end, his father shared his concerns about city life, warning him about the potential temptations and difficulties he might encounter there, but he reminded him to always keep the landscapes of his home in his mind and to be proud of being a son of the sea.

Io is a young man with fine, delicate features, typical of a bishōnen (handsome or beautiful man). However, the story doesn't place particular emphasis on his physical attractiveness.

Her hair is pink and her eyes are red, with a light brown complexion.
