Set in a futuristic Tokyo devastated by a massive earthquake, "Bubblegum Crisis" explores a world where advanced technology and corporate power dominate society. The city is plagued by rogue artificial beings known as Boomers, created by the megacorporation Genom. These Boomers, originally designed for labor and military purposes, frequently malfunction or are weaponized, leading to widespread chaos. To combat this threat, a group of four women forms the Knight Sabers, a vigilante team equipped with cutting-edge powered armor suits.

The Knight Sabers consist of Sylia Stingray, the enigmatic leader who finances and orchestrates the group’s operations; Priss Asagiri, a rebellious biker and rock singer with a tough exterior; Linna Yamazaki, an optimistic and athletic newcomer to Tokyo; and Nene Romanova, a cheerful and tech-savvy hacker who provides critical support. Each member brings unique skills and personalities to the team, balancing their personal lives with their secretive missions against Genom and its Boomers.

The narrative unfolds through episodic conflicts, with the Knight Sabers confronting various Boomer-related incidents while uncovering deeper conspiracies tied to Genom. The corporation’s shadowy leader, Brian J. Mason, and its ambitious projects, such as the creation of advanced Boomers and humanoid prototypes, pose escalating threats. The series delves into themes of corporate greed, technological ethics, and the struggle for autonomy in a world increasingly controlled by machines and those who create them.

Throughout the series, the Knight Sabers face personal challenges and moral dilemmas, often questioning the consequences of their actions and the blurred line between humanity and artificial intelligence. The interplay between their individual struggles and the broader societal issues creates a layered narrative that balances action, drama, and speculative science fiction. The series concludes with an open-ended resolution, leaving room for interpretation and further exploration of its richly constructed world.
