在高中二年级时, rebellious yet intriguing teenager Kensei West (voiced by Shion Kibayashi) forms a group of misfits called "The Windside Crew" with his companions Horizon and Long Mountain. However, an unexpected encounter lands him in the Game Development Club, which is on the verge of disbandment due to a lack of members. Here, he encounters four female students who introduce themselves as bearers of unique "Properties" - Flame Attribute's Chika Sakura (voiced by Kaede Hondo), Earth Attribute's Uzumasa Senju, Water Attribute's Mizuki Nanoha, and Thunder Attribute's Natsume Azuma. Faced with this seemingly surreal club, Kensei is adamant about not joining. Instead, the four girls use their special skills to attack him, hoping to recruit him. Kensei must not only navigate the challenges posed by these mysterious female members but also the enigmatic "Real Game Development Club"...
