Japan engineered an armed powered exoskeleton "Infinite Stratos" (IS) and it became the mainstream of weapons. Since only women can operate IS, women dominate the society over men. Orimura Ichika is a 15-year-old boy and accidentally touches an IS placed in the IS pilot training school. He is found to be the only man who can operate IS and forced to enter the training school. Ichika's busy school life surrounded by girls has begun.

I usually don't review anime, unless I feel like I could really change someone's decision to watch the show. This is one of those cases, but not how you may think.

Infinite Stratos has an all around weak story, why? Because there really isn't much of one. Its a pretty run of the mill mecha/harem show. I'm ok with both of those but I prefer a bit more substance. Here's a short story synopsis: "Guy who can fly mechs for girls goes to all girls mech school, hilarity, action, and ecchi insue."
The story really doesn't explain much about the events that are not part of the read more

IS: Infinite Stratos..
If my Greek isn't so rusty, I would confidently say that "Stratos" means "Skies"
But after watching this anime for the first time, I could conclude that Stratos actually means "Harem"
Why? Because when you're the only guy in a girl school, THERE'S INFINITE HAREMS POSSIBLES! Thus they should rename this anime to Infinite Harems!

Now to tell you the truth, I was a bit reluctant to watch this. Oh sure, harem turns me on, like any normal guy, but mecha genre really turns me off.
But after looking through the mecha suit design, "Hey! You can still see the girls! They're not covered under huge read more

One of the problems with the anime industry is the tendency to overuse stereotypes and themes, and many of the studios in Japan continue to operate under the idea that the shows they create will generate a profit in some manner (regardless of the content), through DVD sales or merchandise. The sad fact is that many producers barely break even from one season to the next, which then prompts arguments of piracy, licensing, pricing, distribution costs, etc, all of which seems more than a little strange as while it may appear that the studios have some perfectly valid arguments, they've neglected to talk about one read more

With the dawn of the second season, I think it's time to revisit an old friend. In this review, I will attempt to describe IS: Infinite Stratos and it's components, then give you it's worth as a series.

The basic premise of Infinite Stratos is set in a world where armored mecha suit, the Infinite Stratos is invented, thus rendering all other technology obsolete. One catch, this suit can only be worn by women.

While this was an interesting premise, the setting itself just attracts questions. Why can only women wear it? What has the effects of this technology had on society? What happened to the political read more

Anime: Date A Live
In both series, the female characters are the dominant characters as they take the skies and brings about the action with their abilities. The main male protagonist gets acquainted with these characters as some of them develop feelings for him.

There is fan service in both series along with some drama, action, and comedy. Romance is obvious between the main male and female character in both series.

They also take place at a school life setting.

Anime: Strike Witches
- Girls-only-power (1 exception in IS)...
- "Wears" machines and flies across the sky
- Action, lots of dynamic mid-air battling scenes
- Clumsy, weak main character with great potential who grows fast
- A cool mentor/leader
- Takes team work sometimes to take down enemy

Anime: Seirei Tsukai no Blade Dance
Both shows are harems where the lead male has a power that only females are supposed to have. In the case of IS, it is the ability to pilot a specialized mecha, and in the case of Blade Dance, it is the ability to contract spirits. In both cases, the lead male is forcefully enrolled into an all-girls academy.
