Musubi is a Reason, a powerful inner philosophy that encompasses a set of natural laws, based on individualism and non-interference with the lives of everyone else. Everyone would have their own little paradise somewhere in the universe and they would be able to be as creative as they want to be in their paradise at the cost of not being able to interact with anyone else. This reason is most closely associated with the Neutral Alignment of previous Shin Megami Tensei games.
Seeing that too many people interfered with the lives of others in the previous world, he vowed to create a world where that was not possible: this, he calls, is the Reason of Musubi.
