Golden Magatama

The Golden Magatama necklace, which is owned by Arashi Kagami, is a tool used to seal Lightning Release Chakra inside of it. It is used by Arashi to gather and seal his immense Lightning Chakra Aura that he has possessed since birth. While unactivated, it seems to be an ordinary necklace. However, when activated, it becomes a Golden Mask that forms on Arashi's jaw. When activated, it returns to Arashi all of the built up Lightning chakra that it has stored since he last used it. The amount of chakra released can vary, from an insurmountable amount to where it begins thunderstorms from beginning, like the first time he used it. Or possibly a small amount to where it only covers his body, like the Lightning Release Armour.
