Lilith was a villainess that appeared in the video game, Valkyrie Crusade. She is a succubus who served as the main antagonist of the story event, Invaders! as she along with her minions, Barbatos and Gullveig, whom she made a deal with a long time ago decided to take over the Celestial Realm.
Not much was known of Lilith's background but it was revealed that she existed during the times in the Celestial Realm. Obsessed with the kingdom and consumed with greed, Lilith decides to make her plan of taking over the Celestial Realm for herself. She then came out from the dwelling and search for her ally to help them to take the entire kingdom.
Eventually, Lilith reached into the kingdom where the maiden named Gullveig lived. She then approached towards Gullveig as she sensed her selfishness before forming an alliance with her. In return, Gullveig gave her the Bewitching Attire which Lilith wore.
Lilith along with Gullveig, were first seen leading an army of Barbatos towards the town of the Celestial Realm. They attacked the townspeople in the town as the maidens of the Celestial Realm, which consisted of Archer, Aludra, Hacker, Lance, Scout, Fencer, Sage, Amethyst, and Painter led by Lonsday were called out to fend off the invasion. Although they manage to took out the Barbatos, they were suddenly attacked by Lilith and Gullveig as Lilith spread the pheromones towards the heroes, thus putting them under her control. She then proceeds to invade Gloomwood where she and Barbatos captured Nadia and Ursula, whom she brainwashed.
However, Hecate was easily defeated by Lilith as the latter then placed her pheromones on Hecate and placed her under her control.
