A highly free-form scenario-playing game, each world and each character has its own story and mission. Unexpected variables may pop up in the plot. When the world line is gently moved, what kind of thoughts and actions will NPCs and players make in order to achieve their own interests? It can also be simply called "The Years I Was an NPC"
Intention: Thousands of worlds, thousands of souls, with freedom as the top priority and the original intention as the way back.
