Nel Ko

One of the best anime, beautiful art, nice progression, nice music, and not the typical "friendship overcome everything" troupe, nice take on an anti hero as an MC. This is also a different take of isekai genre, rather than the person himself got thrown into another world, this time, his whole kingdom/guild is the one thrown into another world. I also like how the MC is not your typical idiotic naive type, he can be kind to people, but he also can be merciless and take drastic measures if needed be.
