In the year Universal Century 0079, the Earth Federation and the Principality of Zeon clashed in the brutal One‑Year War. During a fierce engagement, the notorious Zeon ace Char Aznable slipped into an enemy stronghold and appropriated a prototype mobile‑suit, the Gundam. With that formidable machine in hand, Char guided his comrades to a crushing triumph. Yet an unforeseen mishap with the Gundam"s cutting‑edge systems caused Char to vanish, taking his iconic crimson suit with him.
Six years later, sporadic skirmishes still raged. On a tranquil orbital outpost lived teenager Amate "Machu" Yuzuriha with her mother. While her peers endured grueling prep schools, Machu craved adventure beyond the colony"s borders. That wish materialized when a Zeon squad"s Gundam QuuuuuuX crashed nearby—a top‑tier mobile suit of unprecedented design. Instantly, Machu sensed a natural rapport with the machine and employed it to repel Federation troops. She received help from the enigmatic Shuuji Itou, who piloted a Gundam bearing uncanny resemblance to the one once flown by the missing Char. Together, they discovered that the Gundam"s advanced AI had been compromised, hinting at a deeper conspiracy within Zeon"s ranks.
Unaware of her own combat, Machu"s clashes were observed by a cadre of mecha hobbyists who battled in pairs for sport. These observers, part of the clandestine Mecha League, had been searching for a new champion to lead their ranks. Driven by the desire for excitement and companionship, Machu joined forces with Shuuji, stepping into a succession of escalating clan duels while subtle signs of an impending larger war began to surface. As the battles intensified, Machu sensed that the shadows of the One‑Year War were beginning to reemerge, threatening to engulf her peaceful colony once more.
