Chapter 1739: Interacting with the perfect cool head maid
In the Red Devil Mansion, Remilia holds the highest position.
She is the owner of the mansion and she is like a queen in status.
Behind her, Flandre is the second highest in position.
On that level is Patchouli, the owner of the biggest library in Gensokyo.
Flan, Remilia, and Patchouli are the top dogs of the place.
Other than that, there are other people like the fairy maids working here, the gatekeeper Hong Meiling, and some unique characters like...
The cute and pitiful Koakuma.
Koakuma is Patchouli's familiar, she listens to her mistress' words. Strictly speaking, she doesn't have to take orders from anyone but Patchouli.
Remiliar is the master of the place she calls home so it would be fairer to say Koakuma is in a matrix structure where she might need to take orders from Remilia sometimes.
