child of the night

I am reading a story and I found a point where the plot somewhat falls through it's own hole. The main character died and was reborn into their new life with most of their old memories. Even though they have full knowledge of their sword style from their previous life they can neither read nor write which I feel i just wrong.

On a side note to anyone reading this I am writing a story which takes place in a high school setting. If anyone has any name suggestions for normal human students send them my way. We are talking normal names people not some OC of yours ;3
