In a time filled with wars, environmental concerns and issues, there lives a gaggle of beautiful boys that are the personification of the world's countries. Japan, England, France, Finland, Germany and the rest of the boys attend the World Conference and tackle issues like global warming with a heavy dose of fun. Through multiple world wars the gang will traverse deserts, build mecha U-boats and solve the world's problems together!
Yuuko, Mio and Mai are regular high school girls who lead a normal everyday life. However, with bizarre explosions causing random objects to rain down on their heads, lunch turning into an epic battle between girl and wiener, and students riding to school on goats, their lives are anything but ordinary. Meanwhile android Nano spends her days wishing she were a normal human, but keeping house for her creator, the playful and immature child genius Hakase, dealing with talking cat Sakamoto, and trying to keep a hold of her multitude of easily-detachable body parts, her dream is far from a reality...
Wakame High School has its fair share of weirdos, and transfer student Fumiya "Fuumin" Okometsubu is about to meet the strangest one of all. Planning to make one hundred new friends, the first to step up to the plate is Masaru Hananakajima. Becoming an unwilling student in Masaru's secret martial arts style, the two embark on enrolling more unsuspecting victims to learn the "Sexy Commando" way of fighting. Recruiting Kyasharin, the feeblest strong man in the world; and Kondo, the aspiring manly man; the group embark on a voyage of moronic triviality. From an outrageous sleepover to playing the baseball Game of Honour, the team must finally pull together and remove their pants for the National Sexy Commando Tournament!
Sexy Commando is about students learning martial arts in high school and Hetalia is a show where countries in anthropomorhpic forms in a WWII era interact with each other. They can't sound more different, can they? Yet, I'm making this recommendation because they both share such striking similarities in the way they use scenes that make you think "WTF was that?!" while laughing your head off.
Both of these are funny gag comedies that parody history. Both series do a good job of lapooning historical figues and situations. They both have fairly simplistic art styles and can look rather crude at times but that doesn't take away from their charm. I think the short run time of both shows make good use of their short episodes and pack in a lot of humor. I also think the short run time times them from getting repetitive. If you're looking for a short show that won't take up much time both of these shows are good options.
Yui, Yukari and Yuzuko have just entered high school, eager to have a great time. They quickly become the sole members of the Data Processing Club, using the computers frequently to look up information and find interesting videos. Whether they're debating the merits of sauce on curry bread, trying to determine how some women manage to have huge breasts or dealing with the sweltering heat, these three friends will also manage to have fun in the process.
Both are humour series with a lot of cuteness, silliness and perviness, while trying to make people interested in learning various things. (Parts of Yuyushikí are basically a wiki walk in anime form, while Hetalia is about history and random historical facts.) They are somewhat alike, so if you like one you should certainly check out the other.
