Manga
A woman who calls Nishi her older brother, and refers to herself as his younger sister. They look so naturally similar that someone could mistake them if they wore the same outfit. Because her true identity is unknown, Nishi tries to get rid of her at first, but they bond over time and end up as roommates. Sayla seems to possess super-human strength for someone her size. She can easily bowl over several large men, or crush Nishi's body when she hugs him. She has a high degree of medical knowledge.
