- A creepy sword received from Alice. Made from 666 melted angels, it can seal monsters.
- “That's the cursed blade, Angel Halo. The original fallen angel created that in order to bring ruin to the angels.” - Valkyrie
The Angel Halo (エンジェルハイロウ) is a special weapon wielded by Luka, replacing his Iron Sword (although he still keeps his former weapon). It is extremely grotesque-looking, and as Luka puts it, “looks like [the angels are] being tortured”. It was given to him by Alice XVI (Sixteenth), noticing he has problems fighting to his fullest as the two leave Iliasburg. Alice says it is the only one of its kind in the world.
The blade was created with 666 melted angels, bearing their power and resentment; as a result the sword has the power to weaken and seal creatures (e.g. an Earthworm Girl twirls into a normal earthworm, an Elf shrinks, a human turns into a scarecrow, etc.), although they can return to normal once they have accumulated enough power. Alice also mentions that because it was forged from angels, it can be used against and even harm them, reducing them to their original holy state; this makes it perhaps the only weapon with which a human or monster can injure an angel. The Angel Halo also makes eerie noises, which Alice says is expected due to the nature of the weapon's creation.
When Luka reached the Sabasa Kingdom, a guard noticed his sword. Luka immediately assumes that the Angel Halo just got him into trouble, although the guard assures it isn’t like that.
Tamamo mentions that Luka’s possesses holy power similar to the Angel Halo, as he sealed Nanabi with Daystar, a magical attack as opposed to a sword slash.
According to Lilith & Lilim, Heinrich was the Angel Halo’s previous wielder and sealed them with it.
As Luka begins to leave the Sealed Sinner’s Prison, the Angel Halo momentarily shines with light, seemingly reacting toward Heinrich’s spirit.
According to Valkyrie, the original fallen angel, heavily implied to be Lucifina in a later conversation with Micaela, created the Angel Halo to counter the angel race, who are immune to anything but holy energy.
Alice later admits that she used the Angel Halo to attack Goddess Ilias when she descended to give her blessings, inadvertently ruining Luka’s chances of becoming a "hero". Although Alice managed to scar Ilias, Alice was easily defeated.
When Luka and Alice inadvertently free Heinrich from the Sealed Sinner’s Prison, he reveals that he did originally use the Angel Halo to combat against Ilias and her angels, but the sword’s holy energy eventually consumed him and thus died out of his recklessness.
Tamamo later confirms Alice’s and Heinrich’s stories of their use of the weapon, also stating Heinrich received the sword from a fallen angel and had it from the beginning of his journey.
Trivia
- 666, the number of angels melted to create the sword, is a reference to the Number of the Beast, often associated with the Devil in Christianity.
- Luka’s attacks during Granberia’s third battle causes her to bleed. According to Torotoro's blog, the sword can be capable of killing, which explains how Heinrich vastly reduced the angel population with the weapon.
- According to Torotoro's blog, Lucifina created the base of the Angel Halo. The weapon's shape and appearance would then be formed when Heinrich massacred the angels.
- There are numerous inconsistencies with the plot involving the Angel Halo:
- The reason for the sword’s creation, how a large number of angels was amassed to create the sword, why Lucifina delivered the sword to Heinrich, what happened to the sword after Heinrich’s failed rebellion up until present day, and how Alice is in possession of it are never explained.
- It is unclear when the Angel Halo was created and when Heinrich received it. Heinrich is said to have possessed the weapon from the beginning of his journey and had used it against Lilith & Lilim, all before he defeated Black Alice. However, Lucifina rebelled against Ilias and became the original fallen angel after Black Alice was defeated. It is possible that Lucifina created the weapon before she became a fallen angel, a title that would stick once she had rebelled against Ilias.
- Heinrich mentions that the Angel Halo partially contributed to his erosion. However, this does not seem to happen to Luka; the erosion on the latter is only stated to be caused by his holy powers.
- Upon their defeat at Luka’s hands, Promestein, Black Alice, and Ilias completely vanishes, as opposed to being sealed. The cause of this is unexplained, though it is likely due to the White Rabbit warping their bodies.
