Template:Rain box animals
This Box Weapon is used by Yamamoto for defensive and other purposes. He can also use this Box to use his Shigure Soen's style techniques which require the use of Water. The Water that comes out of this Box Weapon has the Rain property, tranquility. When used in battle, the Water weakens/nullifies enemies' attacks and renders their attack useless, just like when Yamamoto was fighting Nosaru, Yamamoto quenched the Storm Flames of his opponent with the of this Box Weapon. This box weapon is almost like the Shigure Souen Ryu second form "Raging Rain". This
weapon can nutreulize the storm flames due to the tranquility factor.
