BWH: 90-60-89
Yuiko is Riki's classmate and comes across as genuinely independent—the type who doesn't need much from anyone else. She's got this older-sister energy despite being roughly the same age as everyone around her, which is why Haruka calls her "Anego." She carries a replica katana around sometimes, which is pretty on-brand for her overall vibe.
She's into cute things and cute people, and you'll catch her fawning over some of the other girls in the cast. Academically, she's solid across the board but particularly sharp at math. Born outside Japan, she's still fully Japanese in every way that matters to her.
Her birth name is Elizabeth—sometimes shortened to Lizbeth—but she doesn't use it. She goes by Kurugaya and prefers to keep it that way.
