ゼノヘミア

The target of Gilbert's oath of vengeance and an archdemon estimated to be over 4000 years old.

Her personality is cruel and heartless. She sees all inferior lifeforms as her sustenance. She absorbs the "negative emotions", fear, hatred and despair borne from the hearts of other sentient beings and uses her unique ability to convert these emotions into her personal magic reserves.

 Zenohemia has travelled the Continent looking for souls to prey on to restore her powers. On one such sojourn, she killed Gil's sister and mother and set him on the path of the Demonslayer in search of vengeance against her.

Zenohemia has made enemies of other Greater Demons, notably Chimerius and the Supreme Archdemon. The former went so far as to contract with Gil in hopes of seeing a mere human bring about the demise of his hated foe, while the latter impregnated Gil's mother without her knowledge with the intent of cultivating Gil as the object of his vengeance. 

Zenohemia is quick to realise who Gil really is after seeing his demonic form during their second encounter. 

Zenohemia's scheme to use the Crimson Moon to summon the Slaw horde to overrun the island is just a cover for her true goal of obtaining the twin Angelic blades. Using the red blade, she receives a huge boost to her demonic powers, to the extent she proclaims she can overcome her hated nemesis the Supreme Archdemon.

Zenohemia remembers the experiments of the Angels thousands of years ago and is consumed with hatred against Ekmas after he appears to reclaim the twin daggers. When he plunges the blue dagger into her, she loses her demonhood and is reduced to a mere human. Perhaps because of this, she reveals key information to Gil's party and offers them her shattered horn to use in a desperate attempt to stop the island from being destroyed by the Angels' failsafe mechanism.

Depending on player choice, Gil either finishes her off before the island collapses or she escapes to shore after the ruins are destroyed and is found by the Princess's party and killed by her guards. In the latter case, Gil burns her body rather than allow the corpse be paraded around the island. /
