Yuiko Kurugaya

Often acting as a mature, older-sister figure to her peers, this highly intelligent classmate excels particularly in mathematics. Known for her independent nature and occasional habit of carrying a replica katana, she possesses a soft spot for anything she deems adorable. Although she was born abroad, she remains culturally Japanese and prefers using her surname over her original birth name, Elizabeth. Her commanding yet caring presence earned her the respectful nickname "Anego" among her close friends.
