Chiba

The maid attendant to the three Inohira siblings. (Referred to as "Ochiba")

Chiba enjoys her duties as a kind of caretaker for the siblings, never missing a beat when it comes to helping them or keeping their little secrets. Suga especially takes every opportunity to confide in her when she needs to, which Chiba takes very seriously. She's a woman who can take secrets to the grave, after all. Chiba loves to be with the sibling trio, and even enjoys Katsuyuki's presence when he comes around. Although it can get a little chaotic when two similarly high energy people are in the same place.

Others don't seem to know her family or where she's from exactly, and anytime it comes up as a question, she skillfully evades and changes the topic. She really is a woman of secrets herself...
