Who Defeats Lilith and Naamah in Black Clover?
Asta and Liebe defeat Lilith and Naamah in Black Clover after the devils fuse, with Nacht Faust helping stop their escape before Devil Union runs out.

Asta and Liebe defeat Lilith and Naamah in Black Clover, with crucial assistance from Nacht Faust. Asta first cuts down Naamah individually in Chapter 288, but Lilith merges with the fallen devil to create a much stronger opponent. The decisive victory comes in Chapter 290, when Nacht briefly restrains the fused devils and Asta delivers the finishing strike just before his five-minute Devil Union limit expires.

One naming detail is worth clearing up: VIZ uses Naamah, while Nahamah is another spelling commonly found in fan discussions. Both names refer to the same fire-wielding devil.
Who Are Lilith and Naamah?
Lilith and Naamah are two supreme devils associated with the first level of the underworld and the Tree of Qliphoth. They emerge during the Spade Kingdom raid when the first gate connecting the human world and underworld opens.
Each possesses a terrifying magic attribute:
- Lilith uses Demon Ice Magic, creating supernatural ice capable of overwhelming powerful magic users.
- Naamah uses Demon Fire Magic, producing flames with similarly extraordinary destructive properties.
Their magic is more dangerous than ordinary elemental attacks. Both can affect things that conventional fire and ice should not be able to touch, which makes them especially troublesome for Nacht's Shadow Magic.
The twins also treat combat as entertainment. Rather than immediately finishing their opponents, they enjoy causing pain and watching powerful fighters struggle.
Their first major opponent is Nacht Faust, the Black Bulls' vice-captain, who realizes that their strength exceeds what he can comfortably handle.

Nacht Fights the Twins Before Asta Arrives
Nacht attempts to contain Lilith and Naamah while the battle against the Dark Triad continues elsewhere in the castle.
His goal is not simply to overpower them. He needs to prevent two supreme devils from freely attacking everyone involved in the raid.
Nacht has access to several Devil Union abilities through his contracts with four devils. His unusual combination of powers gives him options for movement, defense, and restraint. For a closer look at those contracts, see why Nacht has four devils.
However, Lilith and Naamah prove exceptionally difficult to imprison.
Nacht eventually uses Monument of Atonement, a powerful technique intended to seal the twins away. Their supernatural ice and fire break through the confinement.
By Chapter 287, Nacht is injured and restrained. The devils are preparing to kill him when Asta arrives in Devil Union form.
Asta immediately cuts off Naamah's hand, interrupting the attack and saving his vice-captain.
Nacht initially wants Asta to leave him and concentrate on the Dark Triad. Asta refuses to abandon him, making it clear that Nacht's life matters more than simply moving on to the next enemy.
That rescue begins Asta and Liebe's confrontation with the twins.
Asta Defeats Naamah First in Chapter 288
With Liebe's Anti-Magic flowing through his Devil Union form, Asta has something the supreme devils have rarely encountered: an opponent capable of directly neutralizing their supernatural magic.
This does not mean the twins are helpless.
Naamah and Lilith initially evade Asta by merging with their respective elements. Naamah can shift into fire, making direct sword attacks difficult to land. Together, the twins unleash a barrage of fire and ice, attempting to overwhelm Asta through simultaneous attacks.
Asta counters their magic and continues pressing forward.
The decisive individual strike occurs when he uses his Demon-Destroyer Sword to neutralize their magic and follows with a powerful slash from his Demon-Slayer Sword.
Naamah is cut through the body.
This is the first major defeat of the confrontation, but it is not the final victory.
Lilith immediately responds to Naamah's damaged state, preventing the battle from ending with one devil defeated and the other still fighting separately.
Lilith and Naamah Fuse into One Devil
Chapter 289 reveals the twins' next terrifying ability.
After Naamah is cut apart, Lilith uses her ice to seize the opportunity and merge their bodies into a single devil.
The result is much stronger than either twin individually.
Nacht senses that their combined magical power has increased enormously. Even someone experienced in dealing with devils is shaken by the scale of what he feels.
Asta, meanwhile, cannot sense their magical power in the usual way because he has no mana.
That creates an unusual contrast: Nacht understands how monstrous the fused devil's magic has become, while Asta responds primarily to the attacks themselves.
The Freezing Sun Attack
The fused Lilith and Naamah combine their Demon Ice and Demon Fire Magic into an enormous attack known as the Freezing Sun.
Rather than simply trying to hit Asta, the devils threaten the people below them.
This matters because Asta's ability to withstand or cut through magic does not automatically protect everyone around him.
The fused devil can exploit that difference by targeting the castle and its occupants instead of fighting Asta directly.
Asta responds by enlarging his Demon-Slayer Sword with Black Divider and knocking the massive attack back toward its creator.
It is an impressive display of Anti-Magic, but the fight is not finished yet.
The fused devil remains active, and Asta's greatest limitation is rapidly becoming more important than the amount of magical power his enemies possess.

Why the Five-Minute Devil Union Limit Almost Costs Asta the Fight
Asta and Liebe's Devil Union is extraordinarily powerful, but their synchronization is still incomplete during this confrontation.
They can maintain the form for only five minutes.
That is a serious problem against enemies who can evade direct attacks, move through their own magic, and take the battle into the air.
The difference between Asta's earlier Black form and this stronger transformation is important. Black Asta and Devil Union are not interchangeable power-ups, and the five-minute restriction belongs to the version of Devil Union he uses here.
The Fused Devils Try to Escape
In Chapter 290, Asta continues attacking the fused devil after turning back the Freezing Sun.
He uses the Demon-Dweller Sword to cut into the enormous mass of magic and pursue the enemy inside it.
His Anti-Magic keeps the twins from relying on their overwhelming elemental attacks to finish him.
For the first time, the fused devils begin to experience genuine fear.
They recognize that Asta can defeat them, but they also recognize his weakness: his Devil Union is almost over.
With roughly one minute remaining, the fused devil retreats.
This is a calculated decision rather than a successful escape. The devils intend to survive until Asta's transformation ends, then attack once he can no longer maintain his overwhelming advantage.
Asta pursues them but cannot close the distance quickly enough.
Without assistance, the twins could potentially have outlasted his transformation.
Nacht Creates the Opening for the Final Blow
Nacht intervenes at precisely the right moment.
Using his Shadow Magic, he emerges from the fused devil's shadow and restrains the enemy long enough for Asta to catch up.
Nacht does not defeat the twins himself. His contribution is to stop their retreat at the critical moment.
Asta then strikes with both swords, cutting through the fused devil and ending the battle.
Almost immediately afterward, the five-minute Devil Union expires, and Asta and Liebe separate.
The timing makes Nacht's intervention essential. He creates the brief opportunity that allows Asta and Liebe to finish an enemy who was trying to avoid them until their power ran out.
Does Nacht Defeat Lilith and Naamah Too?
Nacht helps defeat the twins, but Asta and Liebe deliver the decisive attacks.
The distinction matters when assigning credit for this battle.
Asta cuts down Naamah individually, withstands the fused devil's attacks, counters the Freezing Sun, and delivers the final strike.
Liebe supplies the Anti-Magic that makes those attacks possible through their Devil Union.
Nacht contributes by delaying the twins before Asta arrives, surviving long enough to receive help, and preventing the fused enemy from escaping at the end.
Calling it an Asta-and-Liebe victory is accurate. Describing it as a victory achieved without Nacht would overlook the battle's turning point.
The fight also changes Nacht's relationship with Asta. After struggling against the supreme devils, he witnesses the strength of someone he trained and had initially underestimated.
For readers concerned about what happens to the vice-captain during these battles, Nacht's fate in Black Clover is worth examining separately.
What Happens After Lilith and Naamah Are Defeated?
Chapter 291 confirms the aftermath of the confrontation.
The fused devil's body disintegrates, establishing that the final attack successfully eliminated the twins rather than merely forcing another temporary retreat.
However, their lingering magic remains around the castle.
Nacht brings Asta and Liebe to safety, but Asta immediately experiences the painful consequences of using Devil Union.
He explains that he cannot use Devil Union or his Black form again for approximately thirty minutes.
This prevents him from simply moving straight into another major fight at full strength.
The battle against the Dark Triad and the broader danger posed by the Tree of Qliphoth are also far from resolved.
Defeating Lilith and Naamah removes two extremely dangerous enemies, but it does not end the Spade Kingdom raid.
Liebe's victory over supreme devils also overturns the hierarchy that treated him as worthless for having no mana. Anti-Magic supplies the advantage, but Asta and Liebe still need Nacht's help to use it before their time expires. That is why the win belongs to the partnership without making Nacht's contribution optional.
