Born from the fusion of a deceased human girl's soul and a feline body, this dream-manipulating succubus demon can shift between a black cat and a young girl. After centuries of wandering following the death of her original Magus, she was briefly cared for by Arcueid Brunestud, though no formal contract could be formed between them. Following the events of Kagetsu Tohya, she has officially become the familiar of Shiki Tohno.
