Katsu Kaizou is a very gullible, 17-year-old high school student and a believer in science fiction, aliens, ghosts, UFOs, conspiracies, etc. He thinks that everything going on around him is the result of some sort of alien plot to take over the world. Each story is pretty much self-contained and is completely bizarre. Kaizou joins the school's science club, makes new friends, and ends up coming in contact with all sorts of strange things like log people, deadly sushi, pee-blades, scary infections, robot invasions, ghosts, living dolls, and more!

The first word that came to my head after watching the first episode of Katte ni Kaizou was, "...What?"

I kid you not, this is the weird, dumbest and most insane gag-humor anime I have ever seen...
From the mind that created "Sayonara, Zetsubou Sensei," I have to say Katte ni Kaizou is even MORE absurd, if you can believe that...
Basically, it's Sayonara, Zetsubou Sensei meets Bobobo... Can you wrap your mind around that? No? Me neither... I'm still wondering how an anime like this words... but the thing is: it works, and that's what matters most.

Story: 7/10
It's so dumb, it's funny!

This by far is one of the most unique anime out there. I mean everything is unique, the storyline, the characters, even the animation! This anime can be greatly appreciated by comedy lovers and users who have a passion for let's say 'crazed' storylines. But be warned, most of the comedy in this one are 'dirty', in other words related to sex, and are just weird. Compared to other comedy/gag anime out there this has to be the best.

Now let's take a deeper look at the sound and animation since we identified most of the other areas. I would give the sound a 9/10, since read more

Tha manga of Katte ni Kaizou get spiced up with social critic later on (around volume 6), inspiring the artist into creating something even more awesome, SZS it is. His work tell you a bastardized version of what is hot in the land of the rising sun. He is probably the best social critic mangaka you can think of.

The artist Kumeta Kouji used to be a pure manga comedian with no social critic added, and he did well. Katte ni Kaizou is just another quality comedy filled with wordplay, overaction, and parodies. His older manga is finally animated by SHAFT, with his art direction preserved well plus Shinbo style beautification. Everything about the animated version of Kaizou will remind you of SZS seasons you have watched over the last few years.
These two animes are really similar. Its not only the "comedy" and "school life" themes, which make these 2 hilarious. You simply cant stop laughing, still there is "slice of life" anyway. The only thing i was thinking the whole time, while watching these 2 was, "Japan, you are damn weird!"
If you like funny school stories and weirdness - these two are perfect for you! If you watched one of them already(and you liked it) and still think about if you should see other one, here´s my advice: "do it, faggot! You´ll not regret!"
Careful, they are addictive as hell! You can´t stop until you´ve seen all the episodes!
