Just a reminder that everything she says "becomes true".
Just like she said that "i have amnesia" she started to forget things.
She said that she is a little girl, now she can only act and think like a little girl.
She said that her goal is to find the sage tower, but she probably forgot the reason(to comeback to her original world).
Just now she omitted information about level ups, probably, from now on, she will start to believe that she can grow from battles and forget the concept  of level up.
Little by little she is losing her old self and becoming someone else.
That is the only reason i keep reading this isekai, i want to see her breaking point.
