Ichirou Kodama is Maijima High's English teacher and the Head of Arts Clubs. Kodama's personality is similar to that of Nikaido and he has a tendency to deny students from doing what they enjoy, such as denying the creation of a Light Music Club for Chihiro's band unless they all manage to achieve 100 percent in the oncoming test. Kodama has an insidious nature against Keima, because he cannot do anything about Keima playing games in his class due to the fact that Keima was able to ace all of the tests given out by Kodama.
