Sayuki Kurobane

Weight: 45 kg

Reiji's younger adopted sister. She likes cats and usually plays with them in her free time. She is very athletic as she is good at every sport in school. She is the same age as Reiji. She doesn’t talk much; but when she does, her messages are direct and to the point.

She has a very large rivalry against Momiji, as the two of them never agree with each other. But when they do, it comes off as a one-time​ situation. The two of them constantly get into fights or arguments the moment they meet each other eye to eye.
