@Glomoro I'm the one who first refused to acknowledge those lizards as dragons, but it's just my personal bias. I'm tired of the traditionally mightiest of creatures to be depicted as pitiful, witless mounts. In the West, it was the culmination of a hero's fate to defeat a terrible dragon. Like Smaug, in the forefather of modern fantasy, this bloody series included, capable of single-handedly destroying the powerful dwarven kingdom. Defeating a dragon forever immortalises a hero in the sagas. In the East a dragon symbolises the untameable powers of the nature, like flooding rivers. Of course you already know all this, I'm just writing it here to make a point. So, I'm just personally pissed off when dragons are made totally miserable. This manga even contradicts itself by calling dragons prideful, yet they are happily living in a cage and flown around by idiots, like the rapist wannabe. That's some extreme pride, uh huh. Somebody should donate a dictionary to the author, with "pride" bookmarked and underlined.
Not that I'd be honestly angry at this series. This is hardly worth it. Even among the isekai, famous for lacking quality as a genre, this is quite a cheap one.
