I read the manga a little but ended up stopping because of the quality of the translation but when I saw that there was an anime I decided to wait for a day when my parents were traveling so I could watch it in the living room I finished watching it in less than a week. as a woman I recognize that sexism is given to being a product of time and thats why even though I dont agree I watched it from beginning to end without complaining too much only the sexual scenes I think they should have censored more but I know they didnt because its considered a dark fantasy like Berserk and it doesnt make sense to censor the sex but not the gore. the worldbuilding is interesting taking place in a post apocalyptic world that after the near human extinction some humans are able to use magic through study calling on the gods and creating new spells and being able to cast them through rituals or by charms throughout the anime the rules to be able to use these spells are explained in a way that is easy to understand but still you can know why such a spell is more powerful than another right in the first episode you already realize that the protagonist is an anti hero because of living 15 years as an innocent boy and his personality is very different from the other protagonists of harem instead of taking years just to say that he loves someone he does this right at the beginning despite not liking him harassing a lot of women I find it interesting that he still has a favorite and it is because of him that in most of the anime he has avoided sleeping with other girls and only at the end does this happen but the thing that annoys me the most about him is not even the harassment since the girls started to like it later but when he screams I watched it in japanese and his voice matches his personality but his screams are comical and annoying at the same time at the same time luckily its not a thin scream to the point of hurting your ears. about the animation: it has some 3d models that are used in scenes that have large amounts of monsters but the rest is very well animated the fights the spells the chests are visually beautiful and It dont meke me want to stop watching the anime just to draw like when i see poorly animated animes. conclusion: the worldbuilding is well done most of the characters are interesting the protagonist is very different from the ones in other animes that Ive seen currently making jokes all the time and saying that he will never lose for being the protagonist and charismatic despite being a complete bastard you still want to see him on screen and curious to know what amazing method he will come up with to win because he doesnt win fights just for being the protagonist he is in fact powerful. if you wish to watch i recommend to watch in a group although watching alone it was fun sending screenshots of my friends telling my reaction to each scene and commenting on some jokes so invite your friends without frills to marathon at your house or on call eating pizza popcorn and any other easy to chew nonsense laughing at each episode and trying out ideas for characters and campaigns for a tabletop rpg
