Evangelion is an action, drama, sci-fi and mecha anime. Shinji, Asuka, and Rei are part of an underground UN group called NERV that fights against the aliens that are invading Earth. Why are they invading? They want to reach something in Nerv’s base and usher in a second world disaster like the first one. Each time takes more and more of the characters and shows how fragile or strong, people can be. Some break under the pressure and some become much stronger. This show also pokes at how mucha person can take psychologically.

The parallels are everywhere in this show. Shinji, Asuka, and Rei fight against a set of invading aliens while the characters of Freezing are doing the same. Not to mention too, the aliens, just like in Freezing, want access to an underground facility where in Eva, it's NERV. They do not have magical capabilities like the characters in Freezing, but they still do have superhuman strength and abilities in their Eva.

As I watched freezing, Claymore also came to mind. Claymore is about an Earth set in a medieval time ravaged by yoma. Yoma are demonic predators that thrive on eating humans. Governments came together in an effort to fight back and created the silver-eyed witches known as claymores who have the strength to fight these superhuman demons. Raki is a down on his luck boy being attacked by a yoma who is saved by Claire, a Claymore. Claire starts out as a supposed weak character, but becomes stronger and stronger as she searches for the truth and protects Raki.

Right away, this series has genetically modified women just like Freezing. This show also has a lot of fighting scenes just like Freezing. True in Claymore the yoma are already on the Earth and have been, they are still extremely powerful and require a special fighter to take them down aka Claymores. You also have the theme of a not as strong male being protected by a super powerful female.

Sekirei is about a boy named Minato Sahashi who has performance anxiety. This causes him to fail getting into college and disappoint his mother yet again. By chance though, one day he encounters Musubi, a girl who is under attack. She runs taking him with her and she finds out that he’s a master or an Ashikabi. An ashikabi has the ability to become a partner with some of the 108 members that make up Sekirei. They now have to fight to win the mysterious MBI corporation’s competition. Surprise, the Sekirei are all aliens.

Right away, Sekirei is another harem similar to Freezing. Albeit this time, it’s a bit more forced since it’s essentially stated that Minato can form bonds and become partners with multiple women and pretty boys. There of course is plenty of fighting and action within this harem anime because it is a competition after all. There is a bit of humor mixed in as well. Don’t forget the fanservice too! Sekirei definitely capitalizes on it!

IS: Inifinite Stratos introduces Orimura Ichika who is a 15 year old boy living in a society where men are dominated by women. Why do you ask? Well only women can operate these super armors that go over their bodies called Infinite Stratos. Orimura accidentally gets placed in an IS training school. Suddenly as if by magic, he can now pilot an IS. He becomes the first male to ever enroll in the IS training school. Now the plot really opens up with him being the only male in an all-girls academy.

Like Freezing, this show also has action scenes and there is the ecchi with harem and scifi elements as well! For the harem, I mean, come on, he’s the only guy in a school of all women! What’s for him not to like? These exoskeletons aka IS are also around for combat which is what they are training for. Infinite Stratos does lean a bit more on the harem genre, so this is for those diehard harem fans!

High School DxD is about Issei Hyodo who is essentially hopeless. He has horrible luck and he really just wants a harem. Set in a school setting, he finally gets to go on his first date with a girl! Then though, he gets killed. Great times are had by all for this poor guy. He gets reincarnated by his senpai who happens to be a devil, and she reincarnates him as a devil too! Now she is his master and they have to fight to beat the angels. High School DxD is rich in harem and ecchi with tons of fan service.

High School DxD, just like Freezing, is set in a school setting. You also have a great harem setting with generous amounts of ecchi. Here also, the theme of women being stronger than men in society. This time though, it’s just his senpai who is above him unlike freezing where the women are just too overpowered. That being said, High School DxD is wildly celebrated and loved!

Rounding out this list, I present Hagura Yuusha no Aesthetica as a final show similar to Freezing. The difference here is that for the main characters have already won the fight? No really. The show opens where probably 95% of all anime end. The bad guy has been taken down and they are returning to supposed normal school life. Or not… now the main characters Akatsuki and Miu set out on a new adventure.

Now as for parts that are similar to Freezing, this is an ecchi and action anime along with some fantasy elements. This is again, is another harem although it is a little less blatant in it's presentation when compared to Freezing. In both series, weapons are materialized for battles. The school settings also use a ranking system where sudents can fight to achieve higher ranks. Hope you enjoy this gem as well!
