After the invention of the “Infinite Stratos” powered exoskeletons, the world became quite a different place, with the units only able to be piloted by women and the offensive capability of countries increasingly vastly. After an unusual encounter with an IS unit, it’s discovered that Ichika Orimura is the only male in the world capable of piloting one, after which he is whisked away to the renowned Infinite Stratos Academy. As the only male in a school full of girls, expectations are high, as are the chances of misunderstandings. With childhood friends, hopeful classmates and stubborn rivals appearing, all the form of beautiful girls, Ichika’s time at the IS Academy is sure to be an interesting one.

Before even finishing the first episode of Hundred, Infinite Stratos came to mind. Although men are able to use the Hundred weapons, the fact that every character introduced so far has been female makes both shows feel incredibly similar. The protagonists seem unable to walk three steps before tripping over a new member of their harem. On top of that, the battles with the Hundred and IS units play out in much the same way, as although the IS units are much larger, the weapons they use are very similar.

Although the girls so far haven’t been incredibly similar, the harem aspect is very strong in both series, so if you’re watching Hundred for the girls then Infinite Stratos won’t disappoint. Additionally the important ecchi element is present in both shows, though it’s fairly softcore, and the focus is more on making the girls seem cute than anything else. If you want a show that does basically what Hundred does, just more, then Infinite Stratos is a great watch.

Prince of the fallen Arcadia Empire, Lux messes up while trying to retrieve a purse and finds himself falling into the women’s baths of the Royal Knight Academy. Fortunately his fall is broken by a very naked Lisesharte Atismata, princess of the New Kingdom of Atismata, who is understandably not too happy about his intrusion. After challenging Lux, the “weakest undefeated”, to a Drag-Knight duel, he ends up becoming the Academy’s latest male student.

Much like Infinite Stratos, Saijaku Muhai no Bahamut is based around a school training in the use of “battle suits” that only women are normally able to operate. So as before, the almost entirely female cast is definitely a point in Bahamut’s favor. Along with that, the series starts off with a remarkably familiar duel between the main protagonist and the school’s top girl. We’ll give you three guesses to work out how that ends. Both have a good amount of ecchi, fan service moments, though Saijaku Muhai no Bahamut’s art is certainly the better of the two, from the first steamy bath scene, to the satisfyingly tight combat suits the girls wear.

In addition to the art, Bahamut’s story feels more solid than Hundred’s as well, with the story progressing fairly quickly, but still managing to introduce the majority of Lux’s harem with ease. If your weekly dose of Hundred fan service and cute girls isn’t enough, then Saijaku Muhai no Bahamut can easily fill that void.

After the appearance of humans with special abilities, known as Genestella, schools like Seidoukan Academy were created to train young ability users. A new student at Seidoukan, Amagiri Ayato starts off his school life with style, by accidently peeping on Julis Riessfeld changing. A princess and powerful fire user, Julis challenges him to a duel so she can kick his ass, which is fair enough really. Along with the appearance of a teasing student council president, a childhood friend, and damsels that need rescuing, it might be a while before Ayato gets around to his true objective: finding his missing sister.

With its second cour currently airing, Gakusen Toshi Asterisk is one of the more recent and popular harem shows, and rightfully so, with a kick ass sound track, pretty art and, amusing characters. While not the most original of concepts, Gakusen Toshi Asterisk gives us the same fun and easy to watch entertainment that Hundred does, with some cool battles, cute girls, and a well-paced story to keep things moving.

If you’ve not already, why not catch up on the first cour now, so you can keep up with the second cour’s latest episodes as they air this season. We promise it’ll be worth your time!

Blazers, humans capable of using magical powers to materialize weapons. Ikki Kurogane is a new student at Hagun Academy, an academy for Blazers, and one of the worst students at that, an F rank Blazer. After catching one of the academy’s A ranks, Stella Vermillion, undressing, she’s quick to challenge him to a duel, with the winner taking ownership of the loser. But Ikki isn’t quite the F rank weakling everyone thinks he is, which Stella’s about to find out the hard way.

Plot look familiar at all? Not only did Rakudai Kishi no Cavalry and Gakusen Toshi Asterisk air in the same season, but the two were known for their incredibly similar plotlines, so you can see where we’re going with this recommendation. Much like Gakusen Toshi Asterisk, Rakudai Kishi no Cavalry shares the same battles, plot themes, and fan service as Hundred. On top of that, the first episode duel with the school’s “queen” shows up again.

Though don’t let all that fool you, Rakudai Kishi no Cavalry gets a little bit darker than the other shows listed so far, and is more of a romance than a harem despite the number of cute girls. There’s even another male character amongst the main cast, which in these kinds of shows is generally the signal for “we’re taking this plot kind of seriously”. A solid series all around, Cavalry is ideal if you’re after something like Hundred, but with a little bit more substance, and a little bit less ecchi.

In a world where magic is as real as science, those with the ability to use it, magicians, hold tremendous power over those who cannot. Tatsuya Shiba, a magician whose powers cannot be measured by normal methods, has just enrolled at the prestigious First High School, along with this sister Miyuki. After being assigned to the Second Course for weaker magicians, questions begin to rise when Tatsuya’s true strength surfaces, as in-school quarrels get out of hand, and outside forces start causing trouble.

If you love watching over powered protagonists kick ass, few shows do it better than Mahouka Koukou no Rettousei, with Tatsuya going from zero to hero, and beyond with no apparent difficulty. Another school based sci-fi show, like Hundred, Rettousei spends most of the series outside of boring classes, and more time handling bad guys and terrorist organizations.

Although certainly featuring some fan service, Rettousei focuses more on plot and character development, with a decent sized cast and enough time to establish a solid story in its 26 episode run. Mahouka Koukou no Rettousei feels like the school, sci-fi anime that so many recent series want to be. Although it certainly has a more serious feel compared to Hundred, Rettousei is definitely a show any fan of the genres will enjoy.

Throughout the world there are humans who retain memories of their past lives called Saviors. Able to use Ancestral Arts known to their previous selves, Saviors serve to protect the world from evil creatures known as the Metaphysical. Moroha Haimura is one such Savior, now attending Akane Private Academy and trying to piece together broken and half formed memories of his past self. But with the appearance of a girl who was once his ancestor’s little sister, and another who’s quick to get cozy with him, it becomes evident that Moroha had no one past life, but two.

While Seiken Tsukai no World Break focuses on magic rather than science, it has a very similar set-up to Hundred with an amnesia ridden protagonist, a school for groups of special ability users, and an invasion of dark creatures. In fact the first few episodes play out like a fantasy version of Hundred, with duels, a protagonist surprised by his incredible powers, and girls in need of saving. One of the most notable differences is actually the show’s harem, with both series having quite different character designs for their main heroines.

In terms of ecchi, World Break isn’t quite as intense as Hundred, although significant fanservice is certainly present, with tight battle suits and ample chests a frequent sight. Seiken Tsukai no World Break focuses a lot on action and fight scenes, so if you’re into awesome magic and epic battles with mythical creatures, World Break might be the show for you.
