Personality
Lilia is very arrogant and prideful and is not beyond committing deplorable crimes such as mass murder to get her way, and often looks down on her opponents and sees them as weaker than her.

Her pride and arrogance leads her to desire the destruction of the entire world, for no other reason than to prove that she can. When Rimuru asks her what is her grudge against her world, she tells him that holds no grudges and just wants to prove herself as the most powerful. However, this arrogance also proves to be her downfall, as she underestimates her opponents and disregards their power.

History
Lilia was once an apprentice of Merlin, and learned the basis of magic under her master. However, after an incident where she angered the Boar Sin, the girl left to learn magic herself, and desired to one day surpass Merlin as a magician.

Years later, Lilia, believing her magic to be more powerful than that of her former master's, decided to prove it by summoning a demonic entity known as "The Ruler of the Storms" to destroy Britannia. Fueling her summoning magic by sacrificing dozens of humans she deemed unworthy of living, Lilia casts the spell to summon the demon. However, she ends accidentally summoning Rimuru Tempest and his friends, Millim Nava and Benimaru. Initially confusing the slime with the Ruler, she attempts to convince him to fulfill her wish, but, shortly after, she realizes her mistake and tries to kill him. However, being unmatched to Rimuru's powers, she decides to escape.

Later, after the Sins and Rimuru's allignance, Lilia begins experimenting on the creatures that came across Britannia due to the space-time disruption caused by the summoning, including Lizardmen and Orcs from a diferent time period of the Jura Foresy, stripping them of their sentience and transforming them into brainwashed minions. She then casts a forbidden spell that causes any damage they take to be converted into energy and transferred for her.

After the group manage to find her hideout, she reveals the curse placed on the creatures and resurrects the Orc Disaster to absorb more of the group's powers. Having absorbed enough energy, Lilia transforms into a much more powerful demonic form and attempts to kill the Sins and Rimuru. However, she is defeated and, before being able to escape, realeses a destructive tornado on a last attempt to kill her her enemies.

Later, weakened and converted back to her human form, she decides to look after allies that share her ideas and mindset. Then, after some failed attempts, she is able to summon a mysterious woman named Valenty, her first ever friend and new ally to her goal's achievement. The Sins track Lilia down, but she and Valenty escape after Valenty awakes a mysterious power. Shortly after, Lilia decides to create her own group to confront the Sins and bring the calamity to the world, entitled as The Seven Disasters.

Some point after Valenty's departure, Lilia reunites with her after sensing the enormous amount of magic power used by her teammate and after using the crystals collected by her friend in Balleno, she is able to summon the brand new member of the Disasters, Eastin Anamabyllis.

Some time later, she's surprised by a sudden attack of Merlin, being captured by her in the process. Before being taken away, she asked Valenty to search Eastin for help.

Later, she is able to escape from her space-time prison and, with Eastin's help, is able to defeat both Gowther and Ban wich where waiting to ambush her friends, being able to escape once more and reunite with Valenty and her new companions, Eastin and Mono, officialy join them.

Times later, she is able to summon new members for her team, the Dungeon Conqueror, Shin, and the Lunatic Destroyer, Roxy. However, for unknown reasons, she started to loose control of hers powers afer the new members' summoning.
