Color of the Soul

Every *Bushi* has a different colour soul, and when a Bushi touches a *Kitetsuto* the materials in the sword shine and reveal the colour of the soul. In total there are 5 different colors red, white, green, yellow and blue. Out of the five, red and white are the most rare. Most Bushi have only one of these colors but there is one known exception, that being those with black souls who can manifest up to two colors.

## White Soul

Users with a black soul are said to be masters of the *Touki* (Sword Spirit), this is a unique condition caused by having a black crystal within oneself or being the host to the Obsidian Goddess. Black crystal users are shown to have another color as well as the black crystals they possess. All black crystal users with the exception of Musashi seem to belong to the Obsidian 8.They are known as an *Imbito* (Taboo People) due to the myth that they will always be rejected by a Kitetsu Sword.
