Hey everyone, this will be quite a typical Tensura reaction. In which a supernatural entity kidnaps the characters and tells them to react. Also, this is like a semi-canon| semi-AU type situation so there might be quite a few things which are like totally different from the Light Novel. If you think there is something that according to you is not canon you don't need to tell me, it is most likely because of the AU.
