Chaos Mode is a game mode that introduces many new events and alternate paths to the game's story. Many of the events are random or depend on a hidden number created at the start of the game.
After clearing the game five times, you will be able to purchase the Chaotic Key from the Vending Machine in the Developer's Room for 999999G. Alternatively, even if you haven't cleared the game five times, you can still purchase the Chaotic Key from the treasure chest as long as you have 999999G. After purchasing it, you will be given the option to enable Chaos Mode when you start a new game.
Chaos Mode also introduces a mechanic called Surplus Fate Energy. It is obtained when original characters are killed or when characters who lived in the original manga are killed. Certain events require high bad karma to obtain the Surplus Fate Energy. Surplus Fate Energy is required to trigger some events.
Skipping a cutscene using King Crimson will cause the game to skip any Chaos Mode events that occur in that scene.
