Apparently, many members of the Self-Defense Force have military backgrounds, which may be a contributing factor to their over-patriotic tendencies, not to mention why they were not disbanded by the school in the first place. They also act as the school's disciplinary force, enforcing the school's laws by violent means; Rivalz also commented that they ruined the mood of the academy and were more like vigilantes than legitimate enforcement. They do, however, seem to legitimately care about the school, even organizing a nightwatch to protect the campus.
They are also very discriminatory against Japanese, assaulting them even for minor offenses such as obstructing walkways. They also overreact to the vandalization of school property, even pulling a gun on those who deface the statue of Clovis.
- The Self-Defense Force wore standard uniforms with the addition of gloves and an armband on their left arms, possibly inspired by the SS of Nazi Germany but show more similarity with the Orpo or the Imperial Japanese Kempetai in our world. They were also accompanied by a flag-bearer.
