藤枝小雪

Koyuki is Ryouko's only daughter, and lives in apartment 503 with her mother. As a foil for her mother, Koyuki is the temperamental-yet-less-passive best friend that has had a thing for Kouji since she met him five years ago. Of course, hell would freeze over before she would ever admit she has feelings for him. Even though she is a year younger than our protagonist, Koyuki does not hesitate to put him in his place when needed, and is the stronger will out of the two. This does not mean she outright disrespects our protagonist, however. She cares about him enough that she'll respect his decisions when it comes to serious matters, but at times can see things that he clearly cannot. Being a person driven more by actions than words, she has a tendency to meddle and get things rolling when it comes to the other characters, largely because everyone else is too busy sulking or worrying about things.
