Rito Tsukimi

Rito Tsukimi is the homeroom teacher for David in Kouryou Academy. She just graduated from Kouryou Academy, then became a teacher. She knows all the secrets of the school and is also an acquaintance of Lilith Bristol.

Since David has a roommate of the opposite gender, most of her perverted jokes are directed towards him, which causes misunderstandings around him.

Appearance
Rito always wears a maid dress with bunny ears that makes her weird in the eyes of her students. She has long, dark violet hair that reaches her hips, magenta eyes, pale skin and she has a developed body. She is considered very beautiful and attractive.

Personality
Rito has two personalities. The white Usa-sensei (usagi-sensei) and the black Usa-sensei.

The white Usa-sensei is the good and cheerful girl. She is naturally curious and also very childish and mischievous. The white Usa-sensei also has very good self confidence and thinks that she is too cute when the students can't talk; in reality, they actually don't know how to react. However, the black Usa-sensei is the foul-mouthed teacher that's always angry and belligerent. She doesn't care if she hurts any of her classmates, even if she nearly kills them. She always plays innocent but acts like the black Usa-sensei when David annoys her. This is Rito's true nature, which the headmistress knew about but believed that it would be beneficial to developing the students' skills.

The only common point of the two personalities is both of them always tease David.
