藤島義男

Fusae's younger husband, a teacher at the same school. He is a kind, but indecisive, quiet, and uninspiring man.

He is a geography teacher, but his abilities as a teacher are below average. At the school, he is forced to do chores by other teachers and is ridiculed by the students.

His only experience with sex is with his wife, Fusae. He has a desire to have more, but his own complex and Fusae's aversion to sex make it difficult for him to be proactive.
