Akuma
Akuma (demon) take up the majority of the Earl's army and serve as the "foot soldiers". When one is mourning for a lost relative or friend, the Earl appears offering to resurrect that member for them. However, the raised soul becomes the power source for the Earl's weapon and must obey his orders. In contrast, an akuma "converted" by Cross can resist orders from the Earl. Akuma "wear" the skin of the one who resurrected them. They use this to blend in, as Exorcists cannot tell akuma from human with the exception of Allen. The akuma share a metal core made of dark matter that resembles a simplified human skeleton. Their blood also contains a blood virus, which rapidly travels through the victim's body, marking it with pentacles. The virus can be spread by blood bullets of a high caliber shot by the level one akuma. Eventually, the body crumbles into dust and gives off a poisonous gas. The akuma also evolve into higher levels by killing, gaining strength as they do so, with level four being the highest seen so far. Each level akuma becomes more humanoid than the level before it. As its evolution continues, the embedded soul deteriorates. An akuma-producing plant, referred to as an "egg", is required to create akuma. The egg is badly damaged and a new one is being created. There is a special significance to the evolution of an akuma. If destroyed by a force other than Innocence, the soul is consumed by dark matter and is destroyed.
