- Agent Peacock
- Animal-Eared Headband: Of the bunny variety.
- The Anti-Nihilist: Zange shows shades of this. He reveals that he more or less remembers everything in his past lives, and observes that destiny repeats with all of the atavists coming to the same tragic ends over and over again, implying that he tried but failed to make things better.

Ayumu Warashibe
Another maid who works at the Maison and crossdresses in a
French Maid Outfit. His personality is sensible and wry, which contrasts that of the other maid Chino. He has the blood of a zashiki warashi, which gives him the power to bring great fortune to any household he resides in.

Her power is so strong that she must stay cooped up at her family residence away from other people so she doesn't get overwhelmed by information.
- Aunt Pennybags: The main characters are a bit taken aback when meeting her for the first time; her personality doesn't really fit her status and wealth.
