The Spirit of Rain(S.O.R.) is one of the Five Grand Elemental Spirits.

About
The Spirit of Rain is one of five powerful elemental spirits known as the Grand Elemental Spirits(Godaiseirei), of the Patch Tribe. They are derived from the Great Spirit itself, and like it, constitute a collective of souls. They can be controlled by their respective Elemental Warrior, or a shaman of extraordinary power (like Asakura Hao). The power of the Godaiseirei is unmatched by any other spirit, except for maybe the Great Spirit itself. After Hao stole the Spirit of Fire it was hidden, by the Patch Tribe to avoid any other of the Grand Elemental Spirits to be stolen, within the depths of hell and guarded by one of the four Kings of Hell.

According to Pascal Avaf, The Spirit of Rain can create an unlimited amount of Holy Water. Also according to the recent Kang Zeng Bang Data the Spirit of Rain has the same abilities as the Spirit of Fire to become stronger, by consuming souls.
