While Ichika Orimura departs to visit Kuramochi Engineering's laboratories, an unidentified enemy hacks into IS Academy's core and cripples its systems. To fend off the attack and repair the damage, his older sister Chifuyu enlists Ichika's harem: Houki Shinonono, Cecilia Alcott, Huang Lingyin, Laura Bodewig, and Charlotte Dunois. Together, they utilize virtual reality to confront their opponents in IS Academy's network. Unbeknownst to the girls, a piece of malware named World Purge is activated when they enter the digital realm. The program forces them into fabricated realities, where they each experience an ideal romantic version of their bond with Ichika. Once Ichika returns to IS Academy, it is up to him to rescue the five girls and wake them from this virtual reality.

On a hot day of summer vacation, Charlotte's plan to spend time alone with Ichika at his house is somewhat ruined when Cecilia gets the same idea, later followed by Houki, Lingyin and Laura. The next day, Houki helps out at a summer festival being held at her family's shrine and is surprised when Ichika shows up. (Source: Wikipedia)
