"Do you think you can take me down? I am the true storm and the great apocalypse!"

- Lilia to the Sins and Rimuru after activating her Awakened form for the first time.

is a former apprentice of Merlin and the leader of the Seven Catastrophes appearing in The Seven Deadly Sins: Grand Cross. She holds the title of Lillia of Desire, representing her will on destroying the world as a way to prove herself as a mage capable of surpassing her former master.

Appearance
Lillia is a young woman with light skin, dark purple eyes and short black hair reaching her shoulder.

After activating her Awakened form, Lilia's eyes gets a lighter tone and her hair becomes longer, now reaching her back, and turns light blond. Her body also changes in the transformation, assuming a more curvaceous shape.

Whenever she overuses her Awakened powers and is forced back to her original form, Lilia's hair temporality becomes a merge of her usual hairstyle with the Awakened one, keeping the light blond bangs, inversely similar to Shin's hair.

Personality
During her times as Merlin's apprentice, she was described as a timid pupil, however, thoughout the years after rejecting Merlin as her master, she developed an arrogant, prideful and merciless persona.

After being defeated by the Sins and Rimuru, Lilia leaves part of her arrogance aside, seeing that she's unable to win a battle against the Seven Deadly Sins without help.

Over the time she spent with her friends, Lilia developed a softer side, as she demonstrated to deeply care for them.

For unknown reasons, she dreams with the destruction of the entire world. When she's interrogated by Rimuru about any grudge against her world, she tells him that holds no grudges and just wants to prove herself as the most powerful. However, as noted by Shin, Lilia seems to keep secrets about this dream of hers, which she doesn't talk about even with her allies.

History
Lillia used to be one of Merlin's pupils before the Seven Deadly Sins were framed by Zaratras' murder and was a quite talented magician, specially in summoning and teleportation magic. However, she ultimately abandoned the Great Mage, due to her pride making her think that Merlin was underestimating her by keep persisting on basic lessons.

Years later, after Hendrickson's defeat, she attempted to summon a creature capable of destroying the world as a way to prove herself as a mage capable of surpassing Merlin. She ended summoning Rimuru Tempest, but the Slime declined her wish.

She then started summoming and controlling creatures from different periods of time from Rimuru's world with a forbidden spell which, as they were killed by the Sins and Rimuru's crew, the magical power from the heroes' attacks was transfered to her until she absorbed enough power to unlock a mysterious transformation that would make her strong enough to fulfill her wish. However, she's ultimately defeated by the combined efforts of the Sins and Rimuru and, using her remaining power, she manages to run away by causing a havoc summoning a tremendous hurricane.

With her pride ultimately crushed by her deafeat and her incapacity to control her new powers. Lillia recognize she will never accomplish her dream without help and starts hunting for offerings for her summoning spells in order to seek for allies.

After various failed summoning attempts and having to deal with the Holy Knights and the Seven Deadly Sins hunting her, she's finally capable to summon Valenti. The two woman quickly befriends each other and the otherworldy girl agrees on helping Lillia to archieve her goal, becoming the founding members of their newly-formed group, The Seven Catastrophes.

While Valenti went on a journey to study the world of Britannia, Lillia kept, unsuccessfully, attempting to summon new allies until sensing Valenti in trouble after the Catastrophe got surrounded by Merlin, King and Diane in the caves of Balleno. The mage then came to her comrade's aid and, under her request, while her teammate kept distracting Sins by making the caves collapse, she manages to successfully summon a brand new ally, Eastin Amabyllis, with a crystal filled with magic power found by the Weapon Researcher.

Later, after escaping from the Sins once again, now together with their new member, Lillia and Valenti infiltrated in the Black Magic Hall in order to steal a magical manuscript that would allow the better understanding of the constant failures with the summoning magic. However, the two Catastrophes fall into a trap orchestrated by Merlin and Lillia gets sealed by the Boar Sin in a Temporal Rift. However, with the combined efforts of Valenti, Eastin and the newest member of the group, Mono, Lillia manages to escape once more and, with the manuscript stolen fron the Magic Hall, Lillia and the fellow Catastrophes settle themselves in the Timespace Junction.

Now with her summoning spells fully stabilized, Lillia manages to summon and recruit Roxy, a former war slave that agreed to help the Catastrophes in exchange of food and a place to sleep, Shin, an interdimensional robber summoned after Roxy's complaints about the group not having an attractive man, and Camila, a goddess of the Beastmen race aiming to get revenge on humanity.
