Chitaru Namatame  

, 生田目 千足

Chitaru is described as being kind-hearted and considerate towards others, particularly those who may seem more vulnerable or dependent (like Hitsugi and Haru). From the start, it's clear that she has no intention of harming Haru in any way. There seems to be a strong bond between Chitaru and Hitsugi, though this connection is mostly maternal in nature.
