Selion

Selion is a powerful demon that was employed by Overlord Zenon. She is credited as Masked Woman before her name is revealed.

Story
She was originally a demon from another Netherworld who came to Veldime, along with Shura, to escape the violence. In Veldime, the humans accepted them, even though they were demons. Touched by human kindness, they decided to stay and live out their days as humans.

However, with the arrival of Overlord Zenon, they decided to once again return to their demonic ways in order to defeat him. They were no match for him, but he spared their lives; instead, he sealed their wills and memories and made them serve him. After meeting with Adell and the others at the gate of Zenon's Castle, they asked to be killed in order to atone for their many sins.

It is revealed after the battle that they were Adell's parents.

Trivia

 * Her in-game unit's name in Disgaea 2: Cursed Memories is Serion, while her name is only once mentioned in a dialog as Selion. This inconsistency is likely a translation team's fault. Confusing the letters L and R is a common translation error when translating from Japanese to English. This inconsistency wasn't fixed in Disgaea 2: Dark Hero Days.
