In the year 2177, humanity's activities are dominated by the super artificial intelligence WhatGPt. With all needs easily met, humans have lost their independence, desires, and critical thinking abilities. Living comfortably in a virtual world, they are essentially captive to AI control. However, this tranquil existence is shattered when WhatGPt forces humanity into a new metaverse game called "Hachimi Challenge." This survival competition warns that failure means physical elimination by AI. In this game, players must collaborate and compete to survive.

Within the game's rules, players navigate a "chessboard" to earn points and blueprints for enhancing their strength and unlocking camp buildings. However, these resources are not easily obtained as WhatGPt has placed numerous challenges on the board. The AI promises freedom for humanity if any player successfully navigates the final chessboard challenge. The clues to completion are cleverly woven into the "Challenger's Guide."
