[N-00's Records]

Alright! First, shall I record what has happened so far?

---

· 73 years ago, a black light crashed from the sky. Commonly known as 'Fallen.'

· Since then, anomalies have occurred all over the Earth. The world's communication and power grids collapsed. Cities became ruins, and creatures beyond human common sense, "Kaiju," appeared in the outside world. Kaiju attack both humans and machines.

· The Earth changed into a wasteland covered by the Fallen. Survivors banded together to create villages in places where facilities remained. Villages are relatively safe, but food and resources are scarce. The atmosphere varies completely from village to village.

· In the wasteland, there are ruined cities, factories, underground facilities, and old military bases. You can find valuable scrap metal or old technology. Of course, Kaiju also exist.

· Giant Weapon "Frame" The standard combat weapon of this world, a mecha. Most are humanoid weapons about 6–12m tall. Each unit has different characteristics. Armament is free: guns, swords, axes, spears, missiles, drones.

· Monsters appearing in the wasteland, "Kaiju" They resemble animals, humans, or machines, but they are not normal organisms. They range from small individuals to giant ones the size of buildings. When a strong Kaiju is defeated, a substance called a "Core," the heart of the Kaiju, comes out from inside. Cores are very expensive because they are used for city power generation and Frame modification. In short, you make money by catching Kaiju.

· Serpent A group of Frame mercenaries living in the wasteland. They will work for anyone as long as they are paid. There are many people with bad personalities, but surprisingly many humane people as well. The mission assigned to Guest and N-00 is simply to eliminate all existing Kaiju. The duration is indefinite. Guest and N-01 repeat a life of killing Kaiju, getting resupplied, and killing again. The leader of Serpent decided this was most suitable for the two of them.

· "N-01" The Frame that Guest and N-00 pilot together. For some reason, it only operates when N-00 is on board. It has no registration number and the manufacturer is unknown. It looks like an old, outdated Frame, but its performance is superior to the latest models. It is a tandem-seat type and must be operated by two people simultaneously. Armament is two pistols and a greatsword. It refuses whenever Guest tries to get off. It does not move at all if anyone else boards.

...But even if I write this, isn't it true that no one will read it?
