Where on Earth am I supposed to start with this one? It's one wild ride from beginning to end with as much unpredictability as the universe is vast. So I mentioned in the summary this anime has a lore. I mention this because not a lot of people seem to know that, actually, which is probably because of how completely random and made up everything seems to be. I'll save the spoilers, obviously, because why watch it if I spoil the whole thing in this review? Main point would be though, if you watch it all and still don't understand a bit of it (completely understandable, I didn't either), you can read up on the wiki about all the in detail stuff. But setting lore aside, if you aren't here (or anywhere) for the story of the anime, then it's still worth watching as it is crazy loads of fun to watch. The action scenes are so well animated it gives modern action anime a run for its money, and I don't even think this anime was trying! It's hilarious, goofy, but also serious and sad sometimes. It's a perfect blend of emotion and if you enjoy lo-fi hiphop music there's a 200% chance you'll love this anime based purely on style.

Pros:
-Story is honestly rather interesting and the characters seem well thought out.

-It's just so much fun to watch. It's hard to review this one because of how crazy and random it is. It's simply hard to describe aside from fun.

-Beautiful animation style, unique at that, with downright great music.

Cons:
-I dunno. The plot is hard to get based off just watching the anime alone, I guess.

-Maybe not a con for some, but perhaps too much love interest between the 19 year old girl and the 12 year old boy?

-Not entirely watchable if you have epilepsy. No, seriously. Do not watch this if you are prone to seizures. Maybe most anime, but especially this one.

More pros and cons are hard tot think of due to the nature of the show as well as how short it is in comparison to most of the anime that I watch, but it may also be worth mentioning here that this recently got a 2nd and 3rd season that I fully intend to watch soon and hopefully making a review for those could be much easier! If the text review here alone hasn't done it any justice for you (and I feel it hasn't either, no worries), then feel free to at least take my score for the show into consideration when deciding whether or not to watch. I assure you it's very much worth it!
