Because fantasy is the pinacle of anime industry
Anime directors are incapable of doing a decent medieval fantasy anime. Don't know about manga.
Dungeon Meshi is fun.
People say it has D&D-esque world. I wouldn't know about that, never played D&D before. It's a fun read. Love Marcille.
Kuro is a fantasy, right?
Fucking god where is volume 4, christ it has been far too long and it ended on such a bloody cliffhanger too.
That's because most of their medieval fantasy influences come from Dragon Quest. Nips love that game too much for their own good.
Legend of Legendary heroes felt original, although a bit too high fantasy for my taste I still enjoyed it.
