I decided to introduce this anime because it is very cool! You can see girls wearing hot robotic costume and fighting with the evils!

STORY

In the near future, a Japanese scientist engineers a powered exoskeleton called "Infinite Stratos" (IS). Possessing technology and combat capabilities surpassing those of any other arms system, the IS threatens to destabilize the world. Faced with such an overpowered weapon, the nations of the world enact the "Alaska Treaty", which states that IS shall never be used for militant combat, and that existing IS technology must be equally distributed to all nations, to prevent any one nation from dominating the others. The introduction of the IS does, however, have a major effect on society. As IS can only be operated by women, there is a shift in the power balance between men and women, where women now dominate society over men.

Ten years after the IS was initially introduced, the world has entered a new age of peace. The peace is shattered, however, by Ichika Orimura, a 15-year-old Japanese boy. In a coincidental run-in with a (hibernating) IS suit, it is revealed that he possesses the innate ability to operate an IS. Realizing the potential, the Japanese government forces the bewildered young man to attend the prestigious Infinite Stratos Academy, an multicultural academy where IS pilots from all over the world are trained. Thus, he starts a busy high school life surrounded by girls training to pilot IS.

Briefly, the story is all about an exceptional boy fighting together with many girls around him by wearing a kit called Infinite Stratos.

Hentaily, it contains a lot of plots, and the heroins are cute, so just forget about plots and have fun with the story.

Heroins

Ichika Orimura

Houki is a first-year student at the IS Academy and Ichika's (the main boy character) childhood friend, though they have not seen each other for six years. She has a very long ponytail. Her place of residence is home to a kendo dojo, which led to her early interest in kendo. Houki even competes in kendo competitions at a national level, and was the winner of the national tournament that was hosted one year before the story of Infinite Stratos began. She is part of the kendo club at the IS academy. Her older sister, Tabane Shinonono, is the creator of the IS, though their relationship is strained. Six years ago, Ichika agreed to become her boyfriend if she could win the national kendo tournament of their grade. However, the day of the tournament is also the day the IS was introduced to the world. Due to the familial links to Tabane, Houki's family is placed under government protection and Houki is forced to withdraw from the kendo tournament. Since that incident, Houki resents her sister for moving her away from Ichika and abandoning their family. Despite not seeing him for a long time, Houki still harbors strong feelings for Ichika, as her continuing practice of kendo was her only link to him. She was his initial roommate before the arrivals of Charlotte Dunois and Tatenashi Sarashiki, and tends to get jealous when other girls are around him.

Cecilia Alcott

Cecilia is a first year student at the IS Academy and is an IS Cadet Representative of the United Kingdom. Her family is part of the British Aristocracy. Her father, a spoiled and timid man who had little influence both inside and outside the Alcott family, makes her swear to never marry a weak man (a difficulty due to the shift in social status). Upon losing her parents in a deadly train accident when she is 12 years old, Cecilia is forced to protect her family fortune from those who wish to claim a stake of it. After showing high IS aptitude, she makes a deal with the British government, who, in exchange for protecting her family's assets, wants her to go to the IS Academy as a Cadet Representative to gather data for their latest 3rd-generation model. She was almost defeated by Ichika for the position of class representative but won due to a technicality, but later cedes her position to Ichika. She soon starts to see him as a true man and falls in love with him. She pilots the Blue Tears IS, a long-range sniper-class IS, which can deploy four remotely controlled "drones" for engaging enemies at short and medium range.

Huang Rinin

Lingyin is a first year student at the IS Academy, the class representative of her class and is an IS Cadet Representative of China. As with Houki Shinonono, Lingyin has been friends with Ichika Orimura since their early childhood. She has been in love with Ichika ever since he protected her against four school bullies. Lingyin at first becomes extremely hostile to Ichika after he forgets the details of a promise they made as kids (in which it was implied; although not explicitly stated, that if she became an excellent cook, he would become her boyfriend). She is also called "Ling" as a nickname by others, although in the English dub of the anime, her first name is always spoken as "Rin" (pronounced "Reen"), even in formal situations. Her family ran a Chinese restaurant that Ichika would often eat at before Ling's parents divorced and she moved back to China. She pilots the Shenlong a short-to-medium-range melee-type IS armed with the Ryuhou (Dragon canon), powerful "Impact Cannons" hidden in the shoulder armor.

Charlotte Dunois

Charlotte is a first year student at the IS Academy and is an IS Cadet Representative of France. Charlotte initially calls herself Charles Dunois , posing as the second "male" IS pilot student that was transferred into Ichika's class. However, her plan is to spy on Ichika, discover how he is able to pilot an IS and acquire data from his IS (which at the time was considered the most advanced 3rd-generation unit). Because she enrolls as a male IS pilot, she is paired with Ichika as roommates since they are "both" guys. As a result of this arrangement, Ichika later discovers her true gender when he inadvertently walks in on her showering. Upon learning that Charlotte's father and his corporation used her to spy on him, Ichika decides to help protect her. She later falls in love with Ichika due to his bravery. She pilots the Rafale Revive Custom II IS, a 2nd-generation custom multi-range IS possessing a wide array of interchangeable weapons allowing for fast battlefield adaptation and capable of performing the Ignition Boost. Her weapons, once called upon, can be used by another IS pilot as long as she grants permission. Due to her training to make her a convincing male prior to her entry to the IS Academy, Charlotte uses "boku" (an informal male equivalent of "I") when referring to herself. Following the Silver Gospel Incident in later novels, Charlotte becomes Laura's roommate. Boyish blond French girl.

Laura Bodewig

Laura is a first-year student at the IS Academy and an IS Cadet Representative of Germany. A genetically-engineered super-soldier, Laura is the commander of the German IS special forces, Schwarzer Hase , (German for "Black Rabbit"). She has a red eye and long silver hair; but her most distinct feature being a blackeyepatch covering her glowing-yellow left eye, the result of a failed nano-machine experiment meant to help her pilot an IS better. Laura was under Chifuyu's tutelage when the latter was an instructor for the German army following the 2nd Mondo Grosso, and holds Chifuyu in high regard for helping her and was her role model when she suffered a depression for not being the strongest. Her current name is actually a code name given to her by the German military, as she was artificially created from human DNA.

Laura's original purpose for coming to the IS Academy is to punish Ichika, whom she blames for his sister withdrawing from the 2nd Mondo Grosso (she is unaware that Ichika was kidnapped at the time and Chifuyu withdrew in order to save him).

Maya Yamada

Yamada is the substitute instructor of Ichika's class, possessing a noticeably large bust. She used to be an IS Representative Cadet of Japan. In the anime, her skills become very apparent, as during a training exercise she was able to single-handedly defeat both Cecilia and Lingyin, in their personal IS units, using only a mass-produced Raphael Revive IS. She's very skilled.

Sorry for the long explanations. Now it's time to have some rest!
