Nagisa Aizawa

Asahi's class president. Actually, an alien who came for the purpose of observing Earth. She has a serious and inflexible personality, and is called "Iron Lady" by the students.

Her human-sized body is a precise robot called an "external unit", and her main body is a miniature alien about 10 centimeters long that looks just like it scaled down, with something like a feeler that emits light in response to romantic feelings growing from her head.

Her basic specs are high, but her lack of common sense often leads to her being dragged around by others, her motivation spinning in place, or her proceeding in unexpected directions.

At the time she was a first-year student (before the start of the story), Asahi had once shown her a look of affection, but she bluntly turned him down "before he could confess", giving priority to her mission, and traumatized Asahi (according to his friends, this was a "sneak attack"). Because of this history, she has been disliked by Mikan, who considers her an "unpleasant self-conscious woman".

She is an extremely good cook, and even the arrogant Akane is captivated by the sweets she makes, but she overly humbles herself as a beginner.

Height is 162 centimeters (16 centimeters for the original body). Weight is 48 kilograms (100 grams for the original body). Born on June 23. Blood type AB. She likes cats, Earth's manga, and morning runs. She hates her brother and her immature self. She has a special ability to do most things if she is given an explanation (without realizing it). Her hobby is special training.
