They are pretty much same, they feel is very similar. While watching this show it remind me of the other. I just want people to enjoy them both. They are both masterpiece, so don't miss out.

sea diving, country theme, youth, high-schoolers. Please be advised Grand Blue contains some PG-tags before letting kids watch, its all about jokes lol.

Same set up. Cuteness overload. Funny, lots of humor. Lighthearted sweet and relaxing sometime emotional you have them all. The similarity is there, if you like this you will like that and vice versa. Enjoy!
