Classroom☆Crisis

On the Martian colony known as Fourth Tokyo, Kirishina Corporation’s elite student development team, A-TEC, serves as a classroom where gifted young engineers push the frontiers of aerospace. Led by brilliant instructor Kaito Sera, the group looks forward to welcoming a new transfer—until it turns out to be Nagisa Kiryuu, the newly appointed chief of A-TEC and the CEO’s younger brother, sent with orders that could end the program entirely. With their future on the line, Kaito and his students race to produce a successor to their formidable X-2 rocket, while Nagisa pursues his own agenda within the company’s upper ranks.

As their goals collide, the struggle spills beyond school walls into corporate maneuvering and hidden schemes inside Kirishina. Alongside Kaito’s sister Mizuki and A-TEC test pilot Iris Shirasaki, the story weaves intrigue, political conflict, and an unexpected thread of romance as alliances form, histories surface, and the team fights to keep their classroom from collapsing.
