The first kishin(鬼神), or demon god, and the ultimate antagonist in the series. He is known for his exceedingly paranoid disposition and quirky habits such as wrapping his entire head with countless scarfs and wearing five or six layers of clothes. He was fearful of everything, including his weapon partner Vajra, whom he devoured whole, though he can still cough up Vajra to attack. The scarfs on his body are actually made from his own overstretched skin, and can also be used as weapons. As the embodiment of madness, Asura emits a wavelength that causes people to lose their grip on reality and hallucinate. He was one of Lord Death's strongest subordinates 800 years prior to the start of the series. Out of fear he began devouring innocent souls, including his own weapon partner; Lord Death ripped off his skin and used it as a bag to imprison him beneath Death City. He is eventually released thanks to Medusa and her minions, and goes off into hiding to spread his madness across the world. He is rarely seen in the manga though he does become the center of focus for the anime, particularly Arachne's plans to spread his madness across the world.
