altrouge brunestud
A character mentioned in some TYPE-MOON works. Described as having long black hair and red eyes, she resembles a 14 year old girl. Because she could be considered Arcueid Brunestud's sister, she's commonly depicted as a black-haired version of the latter. Some fans think the below drawing of a maid by Takeuchi Takashi is her due to it resembling the aforementioned description.
