Vajra

Vajra is believed to have been the weaponpartner of Asura when he was human. Little is known about Vajra not even their apparent gender. All that is known about Vajra is that they are a small, ornamental form of weapon with two short blades. The weapon is held in one hand and fires off bolts of red light that are extremely powerful and destructive. Out of fear and upon his desire to become a Kishin to destroy said fear, Asura swallowed Vajra whole. It is unknown whether or not Vajra is still alive, allow Asura may still cough up his weapon to fire bolts of red light from his mouth.
