An exoskeleton weapon engineered by Japan, Infinite Stratos (IS) can be piloted only by women. Its power and combat prowess are so immense that an international treaty has been signed banning its use as a military asset.

When it is discovered that 15-year-old Ichika Orimura is the only male capable of steering an IS, he is forcibly enrolled in the Infinite Stratos Academy: an all-female boarding school, the students of which graduate to become IS pilots. At this training school, Ichika is reunited with two of his childhood friends, Houki Shinonono and Lingyin Huang, and befriends Cecilia Alcott, an IS representative from the United Kingdom.

Guided by the legendary pilot Chifuyu Orimura—their strict homeroom teacher and Ichika's older sister—Ichika and the girls will need to use everything at their disposal to defend themselves and their academy against the dangers that will arise during the course of their thrilling school life.

This anime caught my eye as I'm a sucker for harem ecchi anime and mechs. Because of this, I was both disappointed and pleased at the same time, which is weird.

The story is as cliche as it gets for an anime in this genre, but there were aspects of the story where I was pleasantly surprised. The trope "only guy in an all-girl school" isn't used as much as it should, so I'm always happy to see it be used. The story is there but isn't really used unless absolutely necessary. The obvious main focus of this anime is the harem aspect, which is done ...

Mixed Feelings
I either dropped it closer to very end or actually completed it.

This one is another mixed feelings anime, that has things I love and hate simultaneously.

On one hand it has mechas, futuristic environment and a harem full of rather likable girls who are completely obsessed over main protagonist. They actually do fight each other over him. It almost could reach 7 or 8.

However on the other hand, all these females are very violent and brutal, especially towards protagonist himself. They not as much fight each other as they should, as much just vent their anger on him. How it is a guy's fault, if one ...

Honestly I really liked the idea of the story but all the girls were REALLY and I mean REALLY annoying the "love conflicts" voices make me want to scream into a pillow and throw my computer against a wall, and their always getting on the mc's ass about them being better than him and about how he's not doing things right and that's the entire show. I would like to say that was just the beginning of the anime but it was the entire 12 episodes this was probably one of the worst animes I have watched in a LONG while.
