Undead (屍鬼, Shiki, lit "Corpse Demon"), or sometimes simply referred to as Zombie or Grave, is a race of demons mainly composed by the undead. They are typically enemy only demons who employ Physical or Dark attacks and are weak to Fire and/or Light attacks. They belong to the Evil Spirits species and are Dark-Chaos.
"Corpses possessed by spirits, rarely by their original ones. Their personalities remain as energy moving throughout their bodies (like with Elementals), and they can communicate, but often ambiguously. If a person’s spiritual ability was strong enough in life, they may wish to continue inhabiting their body."
