Infinite Stratos (IS), a weaponized exoskeleton system, has become the dominant tool of warfare and conflict. Unfortunately for the men in society, only women are able to operate Infinite Stratos... with very few exceptions. One of those exceptions is ORIMURA Ichika, an orphan raised by his older sister who is herself a famous IS pilot. When his compatibility with IS is discovered after he accidentally touches an IS at the age of 15, he's given a scholarship and enrolled in a school that specializes in training IS pilots. Which of course means an... interesting life surrounded by girls for this shy, unassuming boy.
On a hot day of summer vacation, Charlotte's plan to spend some time alone with Ichika at his house is somewhat ruined when Cecilia gets the same idea, later followed by Houki, Lingyin and Laura. They spend the afternoon playing games and making meals together. The next day, Houki helps out at a summer festival being held at her family's shrine and is surprised when Ichika shows up. Her time alone with Ichika, though, is soon ruined by the appearance of Ran Gotanda, who momentarily has gotten separated by her brother Dan Gotanda. Later, Houki attempts to confess her feelings to Ichika, but is instead drowned out by the fireworks.
