Shiraha

白羽

Friendly and studious, Shiraha is a classmate of Nanoka's who harbors a crush on her. Nanoka, however, has little romantic interest in the boy but is happy to rely upon his expert research skills to educate her on the issues she is facing during her trips through time to the 1920s.
While Nanoka is an avid Wikipedia user, Shiraha is able to delve into deeper databases and online searches which seem to amaze Nanoka. He shares his findings with her over meals at WcDonald's and helps to apprise her of topics such as the Great Kanto Earthquake and various spells and historical concepts.
