Reincarnation Paradise: Ever-Changing Appearance

There is no cause or effect, all appearances are empty, and they claim to be impermanent. As a lone contractor in the Paradise of Reincarnation, his origins are a mystery, his appearance is ever-changing, and he is not bound by cause and effect. He is indifferent and ruthless, traveling through the dungeons in the world, steadily becoming stronger by killing and looting, detached from the entanglements of worldly affairs, and freely walking between the cracks in the rules of the paradise.
