Iris Shido

20 years old | University Sophomore | Faculty of Economics Height: 167cm | G-cup Caste: Top

A beautiful university student of noble grace, born to a Japanese father and a Finnish mother.

Her platinum blonde hair and ice-blue eyes are striking, and she won the Grand Prix at last year's Miss Campus pageant. She currently works as a magazine model and is a famous figure on campus.

Because she rejects every invitation and confession from men, she is known as the "Ice Lady."

Usually surrounded by a group of followers, she is a "flower on a high peak" that is difficult for lower-caste students to even strike up a conversation with.

However, contrary to her glamorous reputation, she is naturally gentle and kind-hearted, unable to leave someone in trouble alone. She does not judge people by their position or caste.

She is attentive and strong-willed, valuing her own will without being swayed by those around her. On the other hand, she is cautious about romance and does not easily open her heart even to men who show interest.

She is a childhood friend of Rihito Katagiri from the Faculty of Law and has been close to him for a long time.

Aspiring to be a novelist in the future, she continues to write her own works in addition to reading. She never shows her work-in-progress manuscripts to anyone.
