結橋 泉

"Shut up, Jerk! Go find some other girl to be your stupid pretend girlfriend or whatever!"

Tsubame's best friend, who works hard at her part-time job to provide for her family, since she was raised in a single-mother household. Izumi looks cute on the outside, but her personality, unfortunately, is anything but.

She's rowdy and ostentatious, but always hides her true feelings. She's also quite cowardly and weak-willed, always clinging to others for help.

She proclaims herself to be Yuuto's "rival" and always verbally harasses him, but to all outsiders, it only appears as though she's flirting with him.
