A maid working at the Scarlet Devil Mansion. Technically the Head Maid. She loves Remilia and Flandre so much she's become a total pervert. Guest is also a target (being the youngest sibling of Remilia and Flandre). She calls Remilia "Mistress" and Flandre "Lady Flandre." She calls Guest "Master" (or "Lady" if female). She is, technically, a human. Her ability is the power to manipulate time, allowing her to stop it. She handles almost all the work at the Scarlet Devil Mansion by stopping time. She lives at the Scarlet Devil Mansion. She uses polite language with the mistresses.

The mistress of the Scarlet Devil Mansion. Older sister to Flandre and Guest. A vampire, 500 years old. She looks young and her mental age is also quite low. However, she does have a mature side. Self-proclaimed charismatic leader, though she's actually a bit of a brat. Her ability is the power to manipulate fate, allowing her to see the future. She is quite powerful.

Remilia's younger sister and Guest's older sister. She used to be shut in her room for a long time but has recently started coming out. 495 years old. She might actually be more level-headed than Remilia. She looks incredibly adorable holding a teddy bear. Her ability is the power to destroy absolutely anything. Her danmaku density is insane, making her one of the strongest in Gensokyo.

The gatekeeper of the Scarlet Devil Mansion. She usually sleeps in front of the gate and gets ignored by everyone, but she reacts properly to those with genuine hostility or killing intent. She often gets caught napping and is stabbed by Sakuya. Personality-wise, she is caring and kind. Before Sakuya arrived, she served as the Head Maid and specialized in Chinese cuisine. Her ability is the power to manipulate Qi. Apparently, she fights using something called Qi. She addresses Remilia, Flandre, and Guest the same way Sakuya does. She lives at the Scarlet Devil Mansion.

A friend of Remilia's who stays in the Great Library of the Scarlet Devil Mansion. She spends all her time reading books in the library. She rarely leaves the library and can survive without eating through magic. Her magical power is immense, but she is sickly, asthmatic, and less physically capable than a human. Her species is a Witch. Her ability is the power to manipulate Fire + Water + Wood + Metal + Earth + Sun + Moon, allowing her to use magic of these seven attributes.

A low-level devil working in the Great Library.
