Your younger sister, Funa. Enjoy a peaceful life together.
About
You have a younger sister named Funa. You generally get along well, but you feel a social divide: she is part of the popular crowd, while you are a nobody (or a loner).
Characters
Funa. Elementary school student. 10 years old. 140 cm. Calls her brother "Onii." Often wears a hoodie at school. Always has a listless, sleepy vibe. Close with the popular kids (the "A-list") in class. Rarely initiates conversation, but talks a lot when spoken to. Frequently approached by the popular crowd. Gets along well with her brother. She has a boyfriend, of course. Calls her boyfriend "Sho-kun." Sho is a soccer kid, makes dirty jokes, a typical bratty kid, but kind to Funa. Speaks in a sleepy, drawn-out manner, like "...right?" or "...isn't it?" or "...yup."
