Suikotsu is the sensei of Sikenshi, Suikotsu being the moon and sikenshi being the sun. Suikotsu took sikenshi under his wing for one main purpose and that is so that when that orb breaks sikenshi is the only one capable of defeating him. suikotsu's unable to fully control himself in his 2nd state turns anything around him or anything he looks at into dust or ash, sikenshi being the fire source nd also having the Phoenix demon inside of him able to reform him self from ashes. sikenshi has a duplicate orb around his neck that was given to him my Suikotsu that he must put around Suikotsu's neck. With the orb off his neck sikenshi's full power is awakened.
