Events of 2020
Second Shibuya High Arc
Upon hearing a scream, Yu entered a classroom where he found the girl unconscious on the teacher's desk with an escaped vampire holding her. Partially through the battle between Yu and the female vampire, she manages to stir as she regained some degree of consciousness. Weakened, she could little more than ask for help.
Yu turned to Yamanaka, who was also present, and requested that he get her to safety, to no avail on account of Yamanaka's hesitation. Holding this student's hair, the vampire attempted to drink from her to heal herself but Yoichi tackles the vampire from the side, preventing her from being bitten.
Sometime after this ordeal, she appears well and meets with Yu on the rooftop of the school where she shyly thanks Yu for rescuing her. Blushing, she states that she was the one Yu saved yesterday in case he did not remember. She requests that he takes a letter she made for him, one enclosed in a purple envelope sealed with a teddy bear sticker. She runs off, leaving a blushing Yu to realize that it is a love letter. Yu pockets it as Shinoa arrives, having overseen the encounter.
