This anime brings me joy, I think that's good enough for me to give it a review. People look for things to keep them entertained and happy, kisame kun really does do that by just existing. Bless this shark, bless their friends, and bless the ending theme song that the animators create new images for from time to time. Short but sweet, it's like a condensed slice of life, with all the pleasantness staying but it just being shorter. If you're sad or need some comfort, watch this cute shark as they go out into the world. If this show were javascript, I would writeit as:

watchShow = "unsure"

if(sliceOfLife == "I want to watch"){
watchShow = true;
} elseif(lookingForFightingOrDrama == true) {
watchShow = false;
}

There is no mystery, this is not an anime you need to maul over, you just need to sit and enjoy cute shark. That's it, that's the play. The style is adorable, the plots are simplistic but still cute, and although it is no masterpiece to me, it still brings me joy to watch.
