Urado Shiori is the main protagonist of the Boze one-shot. She is a first year high school student who is saved by Ryudaiji from a vampire. She doesn't make any appearances in the main series, but it can be assumed that she is still alive.
Shiori's personality isn't shown too much as she only appears in the one-shot, but she seems to become easily embarrassed and/or scared. She also somewhat cares about her first impression towards strangers. Shiori seems to have a low self esteem, as she mentions a few times to Ryudaiji that she is "useless".
