Phantasos, or under his moniker, The Phantom is the main antagonist of the Amethyst of Illusions Arc and a secondary antagonist of Ophelia's scenario. Known between the Brotherhood as the "One with a thousand faces", the Phantom is an eccentric murderer with a strange fixation towards Lucretia.

## Appearance

As the Phantom, Phantasos takes many physical appearances due to the power of the Amethyst, but his outfit is essentially the same: a black facemasque that hides part of his face. He also wears a violet hat with a white feather, coupled with a violet robe above a black undershirt. Since Tristan is his host, he has short blue hair and a skinny figure.

## Personality

A narcissistic murderer whose ultimate goal is to seek the heroic antagonist of his story to strike him, -the villanious protagonist- down and thus give his story an ending. He sees in Lucretia this antagonist, as she was the only one who could deny him. It can be said that Phantasos thinks of everyone as potential victims, and thus means to a greater end: his ending.

Phantasos's quirk is that he writes about the victims' life in his notebook. His "signature card" is a cryptic exerpt of the story he is writing. He has an habit of repeating short words and phrases as a way to demonstrate a myriad of stronger emotions, such as excitement, impatience and fury. He also shows clear signs of doublethinking due to talking to himself, as if he is talking to his "accomplice".

## Story

### Background

Phantasos is a denizen of Hell who became Mythra's court jester and strategist upon being summoned. He was defeated by Leif and Saint Timaeus, a Mystic saint and sealed into the Amethyst of Illusions during humanity's war against Daskanians. The Amethyst came into the possession of the Brotherhood of Saint Timaeus, whose members strove to keep the saint's legacy. However, in the last two centuries, they select a member and have tem undertake a ritual to become "the Phantom", becoming one with Phantasos to terrorize Eastern Laigos.

Tristan, a former member of the Brotherhood, stole the Amethyst of Illusions before leaving the group. However, the Brotherhood eventually reached him, swarming Charos with by monsters and setting it ablaze. At Gloomwood, Tristan accepted to relinquish the Amethyst in exchange for the safety of his family, and in return, was forced to become the host of Phantasos and take the mantle of Phantom. Upon taking control of his host, Phantasos would return to slay Tristan's wife and severely wound his daughter, but couldn't finish her because of Tristan's resistance to the demon.

Prior to the Amethyst of Illusions, he found a hopeless young man and admired his talent of mimicry and simulacrum.

### Amethyst of Illusions

The Phantom is ordered by Andreas to capture Thalassa to make her his mistress. He eventually learns of Rean's talent for mimicry and saves him from death by taking him as his disciple. He orders Rean to gain Thalassa's affection during his time with her. At the Black Castle, he is notified of Lucretia's escape from prison and is ordered to prevent her escape. Instead of facing Lucretia himself, he has one of is disciples to masquerade as him and fight her on his stead. After Lucretia comes out victorious, the Phantom decided that she is the one who could give him what he wanted, an ending.

The Phantom had two personal targets: the Hero, the only one with potential to stop him, and Lucretia, the only one he didn't kill and the one who could give him the ending he desires. He proceeded to instruct Rean on what to do during the entire ordeal: to play as the Phantom by carrying a fake Amethyst, while he let Tristan take control of the body, unaware that he is the Phantom. Signing invitations to Lucretia and other pending targets and enemies to Tristan's mansion. He split his invitees in two groups to follow different routes leading to two sides of the mansion. "The Phantom" appears before the Hero and invites them to the mansion if he wants the Amethyst.

He watched all events unfold within the mansion until Gloomwood. Upon the Hero's realisation that the Amethyst Rean carried was a phony, Phantasos retakes control of Tristan's body and congratulates Lucretia and the Hero. He reveals that the only truth in the entire story was that Lucretia is Tristan's daughter and the entire reason he set up the meeting at the mansion, so that she would be led to him, even though he didn't account for the Hero's survival.

After being overpowered by Tristan, Phantasos regains control over the body and announces that he would kill Lucretia in order to torture his host due to his interference. After a final duel, Phantasos is destroyed, effectively ending his control over Tristan.

### Final Chapter

With the treasures under Leif's possession, he uses it to summon the demons associated with them merged with phantoms of Baldwin, Tristan, Magnolia and Satoru in order to intercept the heroes as his four Sinistrals. Tristan and Phantasos' souls and personalities are merged, and they refer themselves as a nameless phantom. as they doesn't remember anything from his past lives outside of the name "Lucretia". Upon being defeated, the phantom utters Lucretia's name a last time before passing to the afterlife.
