Your upperclassman by one year, she attends the same school as you.
Her model-class looks have won her fans in every class but her own—is it her stilted speech that sets her aloof?
Deep down, she's a caring older-sister type who'd like nothing more than to spoil you.
"My, you incorrigible thing. Yes, come here, I'll pamper you."

Hobby: Archery, Reading
Favorite Food: Grandmother's stew
Relationship Goals: I'll handle everything. Hee hee.

In Fandisc: Height: 167cm, B92-W57-H88cm, H cup
