Iwagami Shizuka

The protagonist's classmate at the university.

She has a strong sense of justice, but she is the type that acts somewhat thoughtlessly. Aware of the suspicious​ part-time job that is popular within the university, she tried to stop it but got caught.

Suspected of being a spy, she was forced to become a specimen. Although completely a victim, depending on the route, she may be in the queen-like position as well.
