A ridiculous amount of ecchi fanservice, a group of battle hardened super-powered girls chasing after a bland male lead and a plot that is pretty generic. These shows have it all in common.
If fanservice and ecchi is your thing, then these series are perfect for you, although Freezing is a fair bit more explicit than Infinite Stratos ever gets.
Both these shows are fanservice vehicles for their cast of well endowed females. Both shows involve the girls all fighting, but Infinite Stratos uses mechs to fight.
Freezing is more explicit with actual nudity. If you're looking for some ecchi fanservice with minimal plot then these are the shows for you.
Minato Sahashi was living a normal life; he had just failed his college entrance exam for a second year in a row, and lived a quiet life in a single's apartment. That is, until the busty Musubi fell from the sky on top of him! She is a Sekirei, one of 108 that are destined to fight each other until only one remains; and he or she will ascend to heaven with his or her chosen one known as an Ashikabi. Minato soon finds himself in the embrace of Musubi, becoming her Ashibaki - but his life will only become more complicated. Musubi isn't the last to claim Minato as her Ashibaki, and what's worse, plenty of other Sekirei and opponents stand in his way!
Loads of battles between girls with male partners, and plenty of ecchi scenes with clothes being conveniently ripped to expose breasts during battle.
Yup, fans of one show will probably find the other entertaining for the above reasons.
Both anime are nearly exactly the same, except in one, they are genetically engineered aliens and some are guys. In the other, they are genetically engined humans and they are all girls. In one the villain Is just a big game nerd and in the other the villains are nearly half the entire cast. Also, in one, the make partners are chosen by fate, and in the other, the male partners are chosen by forc- err I mean by just choice.
All the perverted Issei wants is to squeeze bountiful boobs all day long, so he's thrilled to join Kuou Academy, a once all-female high school filled with gorgeous girls. But little did the boy know that after finally getting a girlfriend, she'd turn out to be a fallen angel who'd drive a lance through his heart, killing him on the spot! Luckily, the beautiful and busty Rias, his popular classmate who's actually a demon, revives him under one condition: that he'll become her servant. Now, Issei finds himself in the middle of a fierce chess game between demons, fallen angels and exorcists, and the fates of his new friends lie in the balance!
On the surface these shows may not look too simiilar, what with one being about demons and the church, and the other being about super powered girls who fight for humanities survival. But both have a silly amount of in-your-face ecchi that serves as the main draw in both cases.
The ecchi fanservice in each is pretty much at the forefront of the show, with jiggling breasts and revealing uniforms being present in virtually every scene, as well as more than the odd moment of nudity and sexual scenes. They also share the overused trait whereby the girls clothing conveniently gets ripped in the chest area during battle, exposing their assets every single time.
The plots in each is generally poor, and really contrived as well. But let's face it, most people aren't here for the plot, so if you're here for the ecchi, both of these will be sure to entertain you.
