Dark Release: Black Spear

Amatsu has the unique ability to create dark matter from his whole body and manipulate it at his will. He generally use his power to generate deadly dark aura slashes that can slice through strong human fleshes and building easily. The injuries which caused by his dark slashes cannot be regenerated easily. Although tremendously powerful, this weapon has one major flaw: it tries to devour its own master. It starts with his arms and then covers his whole body. As Amatsu sustains injuries in battle, his ability to control the Dark Spear gradually decreases, which leads to his fighting style becoming more savage. When it almost fully consumes him, he becomes extremely powerful, feels no pain from wounds and loses control on himself. The Dark Spear is also able to absorb an opponent into itself, converting them to dark matter and growing more powerful. This ability is automatically triggered upon the impalement of an enemy.
