I kinda like the manga more than the anime more since I read the light novel, the manga gives quite a lot of information about the world while still maintaining the amazing story which it presents, also, while Arnos's character is supposed to be kinda whimsical(Judging from his actions both in the manga and light novel) the anime kinda skips them and make him looks more refined(sure he is kinda refined but the whimsical arnos is what makes arnos cool in my opinion) and in my opinion, the manga looks cuter(especially Misha and Sasha)
