He lives in the technologically advanced Shizume City and attends Ashinaka High School, a notable high school that is located on an island just outside the areas. Yashiro is friendly with everyone.

However, nothing normal has been happening since the recent murder of Tatara Totsuka, prominent member of the infamous HOMRA.
