Tanaka

Mr. Tanaka was a teacher of Asa Mitaka's class. He was later killed by Yoru, the War Devil, who turned him into a human weapon during her battle with the class president.

Appearance
Mr. Tanaka was a tall man with black hair and parted bangs. He mostly wore white shirt with black tie, and a coat.

Personality
Mr. Tanaka was a kind man who values life and the well being of his students. He took special care to make sure Asa Mitaka felt included in the class, including asking the class president to befriend her and apologizing to the class on her behalf for the death of Bucky.

However, he may have been more unscrupulous then he seemed, as it was later revealed that he was sleeping with the class president despite their age difference and student-teacher relationship.
