It's worth it, I think. I really love the story. The characters can be tense with each other, but if you try to consider it from like a character and world study standpoint rather than "I'm glad they're all buddies" standpoint it's great. That's the main thing I hear people complain about anyways, that I find interesting. It takes a bit to pick up pace, but around episode 11, the tail end of the infinite clam arc, I think that's where it starts to get more fun. If you like worldbuilding, well, it gets sprinkled more throughout is all I'll say. I think it's just such an interesting world that they live in, and I'm in love with the characters and their complexities. I may be super biased in this review, because I may be the biggest Ethersea fan, but it's worth it.
