[Remilia Scarlet]
A 500-year-old vampire lord, the owner of the Scarlet Devil Mansion. She has the spirit and ability that match her age, and she is also willful and childish that matches her appearance.
“Let’s hold a party tonight!” It’s not an anniversary, nor is it anyone’s birthday. Such abrupt dinners are commonplace in the Scarlet Devil Mansion.

[Sakuya Izayoi]
The head human maid of the Scarlet Devil Mansion. As Remilia’s impeccable servant, she can serve the dishes requested by everyone to the gorgeous table with just a snap of her fingers. Although only she knows how busy she is after stopping time…
Even the picky Remilia praises the delicacies made by Sakuya herself.

[Flandre Scarlet]
A vampire 5 years younger than Remilia. She has the power to destroy everything.
Coupled with Flandre’s fluctuating emotions and belligerent personality, her existence seems to be a time bomb in the Scarlet Devil Mansion.
She is locked in the basement and rarely attends banquets. After the Scarlet Mist Incident, thanks to the communication between Reimu and her group, this time bomb did not cause any bad events.
Although it is a common dinner party, I still hope that there will be no chaos
…

[Patchouli Knowledge & Koakuma]
As the brain of the Scarlet Devil Mansion, the witch who lives deep in the underground library—
Patchouli did not have the energy to devote her time to the management of the library, so the little devil seemed to be given the position of librarian.
Although the black and white mouse that stole the book escaped again today, she also accidentally harvested some rare ingredients in the Scarlet Devil Mansion during the chase. Why not give it to Sakuya to make good use of it.

[Hong Meiling]
The gatekeeper of the Scarlet Devil Mansion, she eats and sleeps together with the others in the Mansion. Even though she is often punished by her human superior, Sakuya Izayoi, when she is lazy, she still admires Sakuya’s strength and her loyalty to Remilia from the bottom of her heart.
Sometimes, she also hopes that Sakuya can be as lazy as she is.
