桜瀬由美子

Masaru and Akira's classmate and also Akira's childhood friend. She lost her parents in a traffic accident when she was a child and is now currently living with his uncle alone. He works as a teacher and, according to her, is really kind and gentle, who always helps him when she needs it.
It's not very unusual for her to be absent from school due to her very sudden fits of asthma, a chronic disease she holds.
She too actually holds feelings for Yukinojou from the time he saved her during one of her asthma attacks, albeit he barely remembers it by now./
