The Hekisoujo (碧双珠, blue-green paired gem) is a miraculous gem that accompanies the Suiguutou. Both are treasures of the kingdom of Kei. The gem is usually tied to the scabbard of the sword and is blue orb the size of a ping-pong ball. It acts as a balm for wounds, illnesses, and fatigue. Touching the gem is sufficient to produce a healing effect.
