In a world of magic...
Where the protagonist is very talented at magic...
He immediately tries to make a physical weapon and is interested in learning swordsmanship.
I don't understand, why does EVERY manga about reincarnating in a fantasy world turns out like this? Why are the Japanese so obsessed with swords? Why even make the protagonist having talent for magic if you are just going to make him fight with a sword?
This couldn't be more generic.
