It’s not a metaphor and I am worried that it may be related to what butterflies—instead wrote me. The absence of the tail is very upsetting, but I don’t think it was cut, Kazuma wouldn’t kill her and say “Go back!”. I thought it could have become invisible. We have already seen that Kazuma is capable of this. It would make sense to scare her with its absence, forcing her to reach her body again and leave. But I still think this is not what happened. I want to believe that it is due to her realisation. She has become like Father. The moment you recognize that you are tied to a god you lose your connection to earth, I would dare say. If it is the case we have still to see what are the effects of Kazuma’s curse.
