Remilia Scarlet is a powerful vampire and the mistress of the Scarlet Devil Mansion in Gensokyo. She is the older sister of Flandre Scarlet and has a loyal head maid, Sakuya Izayoi, who handles all her needs. Appearing as a petite young girl with pale skin and crimson eyes, her personality is childish and selfish, often acting on whims that nuisance others due to her strength. Mentally like a child, she is curious and spoiled by her maid's devotion. Remilia possesses the ability to manipulate fate and is one of Gensokyo's formidable youkai, reigning over her mansion with fairies, youkai, and staff like the gatekeeper Hong Meiling and librarian Patchouli Knowledge.[1][2]
