Yoshioka Nami

Physique: Smooth and flat childlike form.
Hobbies: Reading shoujo manga (aimed at young teenagers) with passion and mail ordering (as there are no stores nearby, with focus primarily on cute accessories and clothes)
Skills: Karaoke and artistic gymnastics. Also jabbing her moron of a brother.
Weaknesses: Boredom and her mother (a ryokan hostess with an overbearing attitude, she's powerless before her.)

She is the protagonist's junior and a first-year student. She is Toshiaki's sister and also good friends with Jun and Shinobu.

Her family home is a resort ryokan run by her parents, located in Matsukawaooshima along her residence.
* Except for Yoshioka siblings, everyone lives in Futabajima.
Though sick of the hectic everyday of helping out with her parents' fairly popular place, she has never been to the mainland outside of school trips.
"One day, a prince will..."
She only dreams that someone takes her away from this island. Her brother Toshiaki is a typical otaku whose worthlessness further fuels her high ideals. Meanwhile, she seems to admire something about the relatively decent protagonist.
