Komon (小門) though much more known as Teacher, is a very quiet and shy over looked member of the club, but is actually the teacher who is in charge of the club.
Even though she has been has been a teacher at the academy for 12 years, she does not have her own class; she makes up for this by helping around the school. She is very clumsy and often ends up screwing up in anything she tries to do, which tends to make her cry. Everyone at the school including other members hardly take notice of her, often forgetting she's even there, which also makes her cry.
- Without her glasses on she is actually very beautiful and can be mistaken for someone else (as Densuke Mifune has done in the past.) Unfortunately she cannot see without her glasses.
- Despite being the oldest of the group she is quite naive.
- She can usually be seen with Komoe Harumachi.
- In the OAV she is voiced by Chiemi Ishimatsu in the Japanese and Mari Devon in the English.
