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
White souls are the most mysterious, not too much is known currently. White souls are one of the rarest colors. It's said white blade users are those who can use horrifying techniques that surpass the limits of human knowledge.

Black 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. This myth is however false as that only happens when one has no control of the Touki. It can cause black crystals to grow on them and even turn them into a large black crystal if they lose too much control.
