so, she is "becoming" her character, she said "i lost my memories" and now she is actually losing her memories, there is a delay for what she said to become "truth", that is interesting, i don't think i know of a isekai that the main character forgot she got isekaied and them became someone else, will she start to act more like a 8 year old child? Will she be influenced by what other people talk about her?
That is interesting.... but it feels like a normal fantasy with extra steps, if the protagonist will forget about being isekaied, why it is an isekai on the first place? The isekai genre relays heavily on the idea that you don't need to build up your main character, because it is already someone with defined characteristics and personality, to erase it and start over from scratch is a little bit wrong imo
