Sensei

Sensei is a teacher at Kumon-mi High, responsible for an all-girls class of students. To say that he teaches them may be an overstatement. Described by some as "creepy", by others as "hot", and by most "a terrible teacher", strong opinions on Sensei are the norm.

Sensei's memory about much of his past is hazy at best, and unfortunately his students and friends are not very interested in filling in the blanks.
