haven't read the manga or LN, so I can only talk about the story in the anime, and this first part feels like the start of something incredible. The animation and art is top tier, we get a different kind of backstory for each character, this makes each character feel more complete and you feel like the characters are all varied. The story has many points of interest and many twists already, and I can't wait for the next part/season to come out :)
This is one of the best (top 3 for me) of this season and I highly recommend giving this a chance.
