transformation
Want to see dude get Isekaid and excited to do magic and stuff only to find out magic is done through like weaving and stuff and he has to learn all these crafts they derided when they were in the old world but through the process they find it really enjoyable once they sit down to actually learn the weaving and she learns to appreciate and listen to the folks teaching her she kind of sheds all the old world baggage and behaviors that were holding her back and takes her armor she weaved herself and goes out to be a badass assassin in season 2.
re: transformation
The opening credits can have the character having a hard boiled egg in the first episode and shift at some point to them having an omelette.
