イリス・プミラ

She is the one who "awakened" Shuuma as a vampire. Arrogant attitude, haughty language, and young-looking, but her true character is a progenitor of vampires who stayed alive for two thousand years.

Out of the three households, she is the only person still alive who never alternated.

She always interferes with the Embroche family, ever since having a fight with the first Embroche. It seems like she has a purpose in making Lycoris, her familiar spirit, sometimes attack Shuuma.

Despite being a main character, Iris does not have her own route.
