Many years have passed since humanity vanished from Earth, yet the Galaxy Tower hotel in Ginza, Tokyo, continues to operate. At the center of its staff is Yachiyo, a dedicated hotelier robot, along with other employee robots working tirelessly in various departments. Together, they spend what feels like an eternity maintaining the hotel, despite having no guests. As they await the return of their owner and the day humanity reappears.
Now, a small miracle is about to change everything for Yachiyo and her robotic colleagues.
Amate Yuzuriha is a high-school student living peacefully in a space colony floating in outer space.
When she meets a war refugee named Nyaan, Amate is drawn into the illegal mobile suit dueling sport known as Clan Battle.
Under the entry name "Machu," she throws herself into fierce battle day after day, piloting the GQuuuuuuX. Then an unidentified Gundam mobile suit pursued by both the space force and the police appears before her, along with its pilot, a boy named Shuji.
Now their world is about to enter a new era.
The year is 2052—an era of unprecedented peace and prosperity prevails across the globe. The reason for this: mankind has been freed from sickness and pain. Nobel Prize winning neuroscientist Dr. Skinner has developed a miracle cure-all drug with no apparent drawbacks called Hapuna. Hapuna soon becomes ubiquitous... and essential. However, soon after Hapuna is officially introduced, Dr. Skinner vanishes.
Three years later, the world has moved on. But Dr. Skinner has returned—this time, as a harbinger of doom. Skinner announces that Hapuna has a short half-life. Everyone who has taken it will die approximately three years later. Death is coming for this sinful world—and coming soon.
As a response to this threat, a special task force of five agents is gathered from across the world to save humanity from Skinner’s plan. This group is called "Lazarus." Can they find Skinner and develop a vaccine before time runs out?
