Ritsuko Takahashi

Head teacher of class 5-2 of Doumori Elementary, Ritsuko Takahashi is considered the madonna (term for "beautiful unmarried woman") of the school. She is very serious and dedicated to her job as a teacher, but at the same time is very edgy when it comes to the unknown, in particular the spirits and youkai the school constantly encounters. Unfortunately, her nature is a double-edged blade for Nube: while her beautiful exterior makes him desire her and all the things he wants to do to her, her oversensitive nature towards the supernatural makes him tease her all the time about it...and face her wrath as a result.

At the start of the series, Ritsuko-sensei is probably the last person Nube would ever end up with in a relationship. Every time he tried to win her heart, she would knock him away due to being too scared of his spiritual obsessions.
