This ability was something I never heard of at all, though I would say that it's not really an offensive ability. Since the ability could just make the things in the books appear real, it could be used to intimidate the enemies but nothing more than that.
But it's a good kind of ability if it was used properly since it does help me to understand the content inside of the book. Because it's not like I would understand everything since all of the words are written in an unknown language.
Even if I was somewhat curious about the full extent of this power… I decided not to pry any further. After all, this world had already been proven to be full of mysteries.
Of course, I knew that magic exists in the realm that we currently reside in. However, having experienced this kind of magic myself I found it completely unbelievable.
