@DanganYankee This information is from an old Japanese toku wiki ai believe no longer exist so take everything with a grain of salt as the person translated it from there I believe. There was this other lady( pro localizer) that use to be on here that has read the book who confirmed it.
@DanganYankee I have to find it again because it has been like a decade but from my memory the Hibiki thing not being a rider show was something very early. The most interesting part of the book was Inoue and Shira P keeping Asumu although the proficient wanted to cut him.
