If you liked the Infinite Stratos anime, the Anime-Planet community thinks you'd like:
I can't believe that no one else recommendet it. They are both made by 8-Bit studio and got pretty much the same roboter fight story. Aquarion is a battle between two worlds and IS is a harem anime where many teenagers battle each other with robots. But i personaly prefer IS.... both of them are good though
Okay what can I say? The both have the whole boy meets girl(s), with a side of ecchi, and a splash mecha theme goin'. Somewhat predictable, and episodic, yet they both have great character settings.
Shido Itsuka was born in a world where widespread catastrophes of varying size called spacequakes can happen anytime and anywhere, razing everything in the vicinity. When his city's alarm forewarns one impending, the teenager races to his sister Kotori in an attempt to rescue her. But upon his arrival, the spacequake transpires in that very spot, and standing in the middle of the destruction is a beautiful sword-wielding girl. Soon after, he learns she is one of many beings called "Spirits" who cause the disasters, and charming those like her is the solution to preventing them. Effective immediately, Shido must date Spirits and make them fall in love with him, because if he cannot, mankind's destruction may very well be inevitable.
One guy surrounded by superpowered babes with fights aplenty, flash and pizzazz, some heroics and a harem in the making. The guy's natural charisma attracts the babes and in Date a Live, with the aid of an organization bent on getting him babes. Total opposite to the main of Infinite Stratos, who is beyond help. Both have their romantic hijinks, tender moments and are surprisingly good, better than they should be at first glance.
And some totally kickass outfits that accentuate the gluts and chest.
Both of these series feature a group of dominant females as they form a harem with a fairly bland male protagonist who has a special ability. Both series try to do a little bit of everything, with comedy, ecchi, drama and action all thrown into the mixer. Neither are particularly brilliant in terms of plot or character development, but if you enjoyed one chances are high that you will enjoy the other.
Natsuru used to be a typical student with a crush on Kaede, one of the school idols, until one day he awakens to discover that he’s turned into a busty girl! Having been chosen to become a Kampfer by the mysterious Moderators, Natsuru is now required to not only fight other Kampfers, but also to transform into a girl while doing so. Aided by a stuffed tiger, Natsuru must now battle it out with other boobalicious babes and continue to try to get close to Kaede – a task that will now be easier as she’s fallen for Natsuru’s female form! Can Natsuru keep his secret safe while maintaining his double life?
Both are very similar anime with the concept of a male student entering a girls' school, or at least the female area. The male main character has the same powers as the girls for some apparent reason and a lot of the voice actors are the same.
Both involve a clueless guy who has multiple girls swoning over him. Though he does not turn into a girl it is still a very action packed anime that i will watch before all others any day of the week.
A single lucky seemingly useless (at the very least; boring, normal and/or plain) guy, gets into a school mainly comprised of beautiful girls that battle one another as part of their school days with super powers. Except IS is more sci-fi, and Maken-Ki is martial arts. Both male protagonists have a harem of girls after his affection without them having to lift a finger; you're typical harem anime.
While Infinite Stratos has Charles and Maken-Ki! has Himegami as their lovable stand-out characters, both focus on what's most important: naturally charismatic (but not egotistical) love-blind mains and their harem; with antics around a plot-device (Mecha for IS and magical element thinggies for Maken-Ki!).
The plots aren't too important as both are fueled by genericness, combat and ecchi and are stupid enough to completely disregard much of anything sensible. Maken-Ki is by far the more perverted and shameless of the two but irregardless; if you can find enjoyment in the generic antics of either harem-based comedies, you will find some enjoyment with the other.
Fifteen-year-old Tsukune Aono is average in every way; he has no hobbies, less-than-stellar grades and he's even flunked his high school entrance exam. His parents have managed to enroll him in a school, but it's no ordinary school! Tsukune will be attending the Youkai Academy, a place where monsters learn how to co-exist with humans! As the werewolves, vampires, witches and other monsters are required to retain their human forms, Tsukune - the lone human - is able to avoid their bloodthirsty gazes. However, he quickly attracts the attention of a number of devilish beauties including the vampire Moka, a busty succubus and even a young witch! It seems Tsukune's average life isn't so average anymore!
Both anime have similar plots to the relationship. In each case the "Man" is a unique indivdual who is the only one that can be present with the givin situation. In infinte stratos Ichika Orimura is the only man on earth who can pilot an IS system, while in Rosario Tsukune Aono; is the only male human attending the school. In both anime the relationships are very very blunt, but its worth a watch to get a chuckle in.
Both anime have a male protagonist, surrounded by girls fighting over him. The feeling is similar in both animes, tho a bit different. The hillarious situations that Tsukune and Ichika get themselves into are always embarrassing and that's what makes them funny and makes you laugh. I recommend watching both animes if you like comedy and school-like anime.
