Nuo Nuo, as the protagonist in "Leaping to the Second", is a tall girl with a simple and cheerful heart like a child, eager to become a "cosmic driver" one day. As long as she doesn't give up, her wish will come true. But the way to achieve it is Nuo Nuo's true identity. It is the ultimate nemesis machine-nemesis machine No.7, which was made by human civilization according to the legend of the first heroine Gao Zhai law 1 0,000 years ago.

Nuo Nuo, who has lost her memory, lives on the earth as an ordinary girl. Cutting-edge nanotechnology makes Nuo Nuo almost indistinguishable from human beings. Even she supplements her energy by eating. The only thing she remembers is the astronaut she longed for-Nuo Nuo Lily. In fact, it is the first film, in which the protagonist (Kiko) originally ran away from home for his ideal, but was forced by his livelihood to become a handyman in a bar. However, she met the real astronaut Larix by mistake, and Nuo Nuo, who worshipped her, called her "sister" and worked hard in her direction. This simple and cheerful girl was gradually accepted by the once indifferent larch and regarded her as a lifelong friend. In the crisis of larch, Nuo Nuo finally regained his memory and ability, became the nemesis machine 7, and defeated the real cosmic monster-the source of gravity change. The cosmic monster that Larch and others fought before was actually the "Baster Corps" made by one person on the 7th to protect the solar system.

As an early and complete Baxter machine, Nuo Nuo did not adopt the long-used "shrinking furnace", but carried the "rewriting mechanism of physical laws" on his chest and arm, and changed the physical laws with pure mathematical algorithms to achieve the realm of "making something out of nothing".

Although Nuo Nuo is only one person's size, it can easily cut the planet with the Baxter beam, and even create shrinking furnaces and miniature black holes out of thin air. However, due to his limited size, Nuo Nuo couldn't make huge weapons for his own use, so he equipped the "Buster Corps" in Nuo Nuo to command the origin of the first gawk in the universe. Through the gawk on his head ... Because of the disappearance of Nuo Nuo, the Buster Corps, which lost its owner, evolved according to its own purpose of protecting the solar system, but ironically became a cosmic monster, and regarded naked humans with similar power sources as enemies, and remained in a hostile relationship with human beings. At the same time, when the Baster Corps and Nuo Nuo are combined, it will form the ultimate defense weapon of the earth-Diebuster. DIEBUSTER originally planned to use EXELION retreat furnace as power source. Later, the retreating furnace detonated as a black hole bomb and was swallowed up by the cosmic monster. Finally, it could only be attacked in an incomplete state. Introduction of Z3 Sky Prison in Machine Warfare
