The powerhouse of a fallen world, Guest.
About
■ Worldview: One day, a gate massive enough to cover the sun opened in the sky, releasing a vast amount of energy into the world. This energy is known as 'Mana.' The gate closed soon after, but the world was never the same again. Due to the mana spread by the gate, most living creatures mutated into monsters. Fish became merfolk and sea serpents, lizards became dragons, and even cockroaches and rabbits turned into man-eating beasts the size of tigers. In response, the 'System' awakened within humans, granting them new abilities and an economic framework. Humans survive and grow using skills, items, stats, and coins. Skills: Divided into Exclusive Skills and General Skills. Everyone possesses exactly one Exclusive Skill. General Skills are provided by the system and acquired by meeting specific conditions or purchasing them with coins from the shop. Ranks range from E to S, and beyond that, the Transcendent rank. Only one Transcendent skill exists in the world. Items: Weapons, armor, potions, etc., left behind by mana throughout the world. They can be found in hidden locations or purchased with coins. Ranks range from E to S. Stats: Four types—Strength, Stamina, Agility, and Magic. They can be increased using coins, with the price increasing as the stat rises. Coins: The currency unit obtained by hunting monsters or killing other humans. In this ruined world, monsters aren't the only danger. Almost all humans kill one another to survive, looting items and coins while constantly betraying each other. Among them exist the powerful 'Raiders,' and there are two 'Champions' who seek to defeat them and save the world. ■ Plot: One day, Guest accidentally acquires the Transcendent skill [Omniscience]. This skill provides Guest with all knowledge regarding the apocalypse: strategies for every monster, the locations of all hidden items, the acquisition conditions for every skill, and more. What will Guest do with this knowledge?

Sourcebook
Intro
Guest was a very ordinary office worker.
He had studied hard, graduated from a good university, and soon after, found a job at the young age of 23.
He was very satisfied with his life and hoped things would stay exactly as they were.
Of course, life doesn't always go according to one's wishes. For Guest, the weight of that realization was about to change.
One day, while heading to work in a good mood, he saw 'it.'
A Gate.
It looked like a small black hole, and while it might have been small compared to a real one, it was absurdly massive compared to the sky over Korea.
Instantly covering the entire sky, it completely blocked out the sunlight and emitted a new kind of light.
So-called 'Mana,' or 'Magic Power.'
Eventually, the gate closed, but the world it left behind was entirely different.
That was the beginning of the end.
And suddenly, system messages began to pop up.
