Lilith

Lilith (リリス) is one of the highest-ranking devils of the underworld and a devil connected to the Tree of Qliphoth. Lilith resides on the first level of the underworld and acts as its ruler alongside Naamah.

Appearance
Lilith is a tall humanoid with long, light-colored hair. Lilith's face and neck are heavily wrinkled, and Lilith has a dark-colored mask that covers the the upper-right quarter of Lilith's face and extends back past the ear. Lilith also has a pair of upward pointing, dark-colored horns; the right horn juts out of the mask and is longer than the left horn.

Lilith has a dark-colored marking that traces down the neck to the navel and a long, thin tail with ice-like spikes protruding from the tip. Lilith has feathered wings that emerge from the lower back. Lilith's right arm is larger than the left arm and is covered in a pattern resembling shards of ice and has ice-like spikes protruding from the shoulder.

Lilith's dark-colored dress has a deep v-cut that exposes the navel, and connects to the covering on the right arm and shoulder.

When Lilith fuses with Naamah, Lilith's right half is combined with Naamah's left half, with the right side retaining Lilith's ice-like wings, arm, and shoulder while the left side retains Naamah's fire-like wings, arm, and shoulder. Their body is covered in the same dark material with the same deep v-cut that exposes their navel. Some of the material extends out like a pair of long coattails. The upper part of their head is in the shape of both Lilith's and Naamah's masks combined, leaving two eyes, one on top of another, in the middle. Their tail has both the ice-like spikes of Lilith and the fire-like wisps of Naamah.

Personality
Like most devils, Lilith looks down on humans and takes great delight in toying with them.

Biography
When the Qliphoth Advent Ritual opens the first gate to the underworld, Lilith and Naamah emerge and appear in Spade Castle. Lilith immediately attacks Jack the Ripper, who is sent crashing into a wall and then is frozen to it. The two devils both attack Nacht Faust, but his Unite Mode: Felis allows him to dodge most of the barrage. The devils wish to toy with the humans but agree not to attack Lucifero's host, Dante Zogratis. Nacht then enters Unite Mode: Gallus with Walgner, and uses its characteristic, Crow, to stop the devils' movements. He then drags them to another part of the castle through Shadow Magic. The devils are amused by Nacht's abilities as he traps them in his Dark Prison Hunting Ground. They decide to compete with each other to kill Nacht but agree to not fight earnestly. Their attacks force Nacht to continue dodging. After his kick to Naamah fails, he returns to focusing on dodging. The devils question why he does not flee with his speed, to which he replies that he cannot forgive them or their unjust evil.

Not long after, Nacht's Shadow Magic spell dissipates, causing the castle to be engulfed by fire and ice, leaving the mage severely burnt and pierced by frost spikes. Nacht enters Unite Mode: Gallus × Felis and attempts to seal away himself, Lilith, and Naamah in his Monument of Atonement spell, but the devils break out with their Demon Ice and Demon Fire Magic, covering most of their bodies with freezing ice and scorching fire respectively. They restrain Nacht's arms with their magic, causing him to cry out in agony, the sound of which delights the devils. Wanting to hear Nacht's final scream, Naamah reaches for Nacht's throat, but Asta arrives and severs the devil's hand. Lilith laughs with excitement as they have not faced anything so entertaining for centuries in the underworld. Lilith and Naamah trap Asta in a twister of ice and fire, but Asta cuts through it and tries to behead Naamah. The devils disappear into their own magic and then both launch projectiles at Asta, while debating which of them will hit and kill him first. However, Asta pulls out the Demon-Destroyer Sword and neutralizes the devils' magic.

After Asta cleaves Naamah in two, Lilith freezes the other devil and then fuses their bodies together, while laughing at Naamah's loss and the prospect of continuing to play together. The fused devil wishes to hear Asta scream, but when he admits that he cannot feel their power, they unleash huge columns of fire and ice before flying high above the castle. They create a massive freezing sun in order to cause Asta pain from the deaths of everyone below. When they launch the sun at the castle, Asta increases the size of his Black Divider and reflects the sun back at the fused devil. They pass into their freezing sun to which Asta uses his second sword, Demon-Dweller Sword, to slice the sun and then proceed to pass into it to chase the fused devil.

Inside the freezing sun, the fused devils unleash waves of their respective magic to attack Asta. The mage then conjures his Demon-Slayer Sword to nullify the fused devils magic, to which they questions what Asta is and how he is able to neutralise their attacks and harm them. To Lilith and Naamah, all life exists to entertain them but throughout their battle with Asta, they didn’t feel fun, but rather an emotion foreign to them, which Liebe correctly surmises is fear.

The fused devils fly out of the freezing sun to stall time for Asta’s devil union mode to run out and kill him. After gaining some distance, the fused devil smiles and says to Asta that they will crush him, his companions, as well as all humans in the world, to a bloody pulp before he is cut off by Nacht, who restrains them with his magic. Asta then ceases the opportunity to use both the Demon Dweller and Demon Destroyer to cleave the fused devil into pieces as his union mode runs out.

Magic

 * Demon Ice Magic: Lilith uses this magic attribute to generate and manipulate a sinister form of Ice Magic. This frost is capable of freezing anything and everything, including shadows, light, and even invisible concepts. Lilith is also able to turn its own body into ice, which it uses to dodge attacks entirely by merging with and moving through its own ice. Lilith is incredibly proficient in the use of this magic and can create barrages of ice shards, waves of freezing frost, and blizzards that freeze anything in their paths.

Abilities

 * Immense Magic Power: As one of the devils connected to the Tree of Qliphoth, Lilith possesses immense magic power, greater than that of the Dark Triad.


 * Fusion: After Naamah is cleaved in two, Lilith fuses their bodies together. This fusion dramatically increases their magic power, far beyond a simple sum of their previous amounts. They are able to use both of their magic attributes simultaneously, as well as combine their attributes together.

Trivia

 * Lilith was a class of female spirits in multiple ancient mythologies and became a female demon in Jewish mythology.
 * In the Zohar, the foundational work for Kabbalah, Lilith and Naamah seduced Adam and gave birth to the plagues of mankind.
