Youko Shiragami is the main female protagonist of the Jitsu wa Watashi wa series. She is a second-year high school student and the daughter of a human and a vampire, as such making her a vampire-human hybrid, known as dhampirs. Attending a human school under the condition that she keep it a secret, she manages to do so until her secret was exposed to Asahi Kuromine, a classmate, when he caught her unfolding her wings in an empty classroom. Youko has long green hair and orange eyes. As a vampire, she also possesses long canine teeth and wings. Although she is able to hide her wings, Youko is unable to do so with her canines which leads to her avoiding showing her teeth while at school as much as possible. When not hiding her secret, Youko is a very lovable girl to be around. However she's also rather dense, and tends to be baffled by seemingly simple concepts, which frustrates her classmates, especially Asahi Kuromine, to no end.
