Yumi

In a school full of hybrids, Yumi is one of two human-dragon hybrids in the school, along with her sister Kaida. However, unlike her sister, Yumi always has to try her hardest just to get a passing grade. She can never get any sleep at night, and her sleep schedule is unreliable and wacky. Sometimes she’s so tired she forgets about personal hygiene, which is one of the many reasons why she’s one of the most unpopular students in the school. The only thing she seems to be good at is being president of the Archery Club, but even that is being threatened to be taken away from her if she doesn’t get her grades up. Although she enjoys everyone’s company, she has a soft spot for two specific people; her sister Kaida and her crush, who is unknown.
