Oiso is a diver from Matsue Village who was renowned for being the best diver in the village; that is, until she got breasts, which altered and slowed down her diving.

Oiso's skin color is darker than the rest of the cast's, which most likely comes from her being in the sun for a long time. She wears a white headband, a white open shirt tied at the bottom, and a red skirt.

Oiso is a laidback person who likes doing what she does best. She doesn't like her big breasts, mainly because they hinder her diving skills, but also because they don't give her the status that they grant to noblewomen in higher class circles.
