Now for the review lol. The shows not the best but it's not the worst. Its a bit better than average. It does everything mediocre except for the story and character design in my opinion. The characters are original, and have depth. Each one experiences a lot of character development over the 5 seasons. The story reminds me of a pure fantasy story. Like a fairytale out of a story book with lots of twists, turns, and with lots of emotion. Albeit they do use the same techniques and ideas over again as plot devices. However almost all longer animes they do this maybe just not as much.
More than the fairytale story that it first seems like and Many people view it as, I view this as one long love story which isn't mentioned much here but that's what this show is from beginning to end. A story of a boy for 3000 years goes on an adventure to save a cursed girl which is the one and only love of his life.
This season shows the conclusion of the boys adventure and ends the story of the boy and the girl. That's how I viewed the entire 5 seasons and from this perspective the show is really moving and a fun watch.
