Nana

A Homonculus created based on Mia that was with the Iron Golem in the center room of the maze created by Trazayuya. Despite being less than a-year-old at her introduction, Nana has the appearance of an busty eighteen-year-old due to her homonculus background.

Satou became her master after he defeated her previous master, Zen. She calls Mia, mother, due to Mia being her blood provider.

She is the shield-user of the group.
