There are also the teachers at Phoenix Drop High. They can be either helpful or create more problems for Aphmau.

Also, some of the antagonists or those who cause trouble for Aphmau in the Phoenix Drop High setting can be considered important characters. For example, a bully or a rival in academics or popularity.
