Katte ni Kaizou

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. read more 

Fast-paced zaniness and humor. Both are short OVA series that embody this and are pretty much on crack.  

Nonsense adventures, critics to society hidden in jokes, references to other mangas and animes - and even to things in ocidental culture. Everything to make you die of laughter. Katte ni Kaizou is like a Gintama made for the Shonen Sunday universe. 

These two animes are comedies, and most of their jokes are quite perverted. Of the two, Katte ni Kaizou is bit darker than Setokai Yakuindomo. Both are about the everyday lives of a group of high school kids, who are not normal at all.  

Same style of humour, perverted, dirty, arranged mainly with teenager boys betwen them.  

Bizarre humor and a lot of completely ridiculous situations and characters with a school setting. Nichijou is a bit more PG-rated in its content, while Katte ni Kaizou is like a hard PG-13 in contrast, but it's quite likely that a fan of one will enjoy the other. 

Chuunibyou extravaganza with a fast talking male protag in school in some form of club. 

Sketch comedies with an outstanding main charatcer who gets attention from everyone around his school and does crazy things. The comedy style is kind of absurd, but feels very fluent. 

The daily routine of a special teenager with strange superpowers. Nonsense humor and absurd situations everywhere. Very colorful art. 4th wall almost always broken. 

Both share the same kind of raunchy random parody humor so I recommend them if you want something similar. 

Both shows are animated by Studio SHAFT and has a similar, surreal type of humor and strange characters.  

Same author, same fast-paced comedy from beginning to end. Joshiraku is a fair bit lighter on the content rating and social commentary, but both are enjoyable in a zany way. 

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!  read more 

Haruhi and the main in Katte ni Kaizou both believe in supernatural elements such as aliens, UFOs, and ghosts. They have similar settings such as school and the facilitation of clubs. 

both series seem to be shot in a same town, as if it could be the girlish whimsiness of soremachi in the east end, and the adolescent kaizou-madness in the west end. and sometimes they swap sides. 

Both anime have strange clients; Katte ni Kaizou has more perverted clients though.
