Nagisa Aizawa

Aizawa Nagisa is a representative of class 2-1, the same class Kuromine Asahi and Shiragami Youko are in. People around her sometimes call her "iron lady" because she is always acting extremely strict.

In reality, Nagisa is a space alien from a different galaxy with a mission on Earth. Her real body is roughly ten times smaller than that of a human.
