Sword Art Online
Love it or hate it, one can’t deny that there’s something special about this series. Set in the world of Aincrad, the story follows Kirito and his friends as they seek out a way to escape a new online game after its creator traps every player inside until it is beaten. This is made all the harder by the fact that if any of them die in the game, they’ll die in real life as well, their brains destroyed by the virtual headsets they used to access the virtual world.
While it does lose some steam in its second half, the first arc of the series stands out as top quality Isekai with an engrossing world, interesting characters, and gorgeous fight animation. Plus, with a second season and feature length film also available, there’s plenty to dig into should you find it to your liking.
