"There’s nothing that I can’t steal! ...Probably."

Platonic, also known as Phantom Thief Platonic, was a thief from Calgaround in the Kingdom of Elphegort. Taking up the life of a thief under a new name to escape her noble family, the rebellious and free-spirited youth became infamous across Evillious. After her mentor's death, she was hired by AB-CIR to steal the wine glass of Banica Conchita and later the Twin Blades of Levianta from Elluka Clockworker. She was one of Eve Moonlit's incarnations.


Early LifeEdit

Following the death of the daughter of the noble family of Calgaround, Elphegort, the Clockworker's Doll was activated and its demon assumed the child's identity.[1] The girl then grew up in an affluent lifestyle, but eventually became tired of the restrictions her life gave her. Desiring freedom, she ran away from home and was cared for by an old thief. Choosing to emulate her caretaker, "Platonic" took up the life of a thief and made it her goal to one day buy a house and fall in love.

Under her master's tutelage, she became an excellent thief, using the Association to help with her heists; she soon became infamous throughout Evillious, with her wanted poster in every country. During this time, Platonic's master introduced her to AB-CIR, who tested her and found she was incapable of casting magic spells. The old thief also told Platonic of how AB-CIR had defeated the wicked I.R. in battle, though his hand was severely burned during the battle.

Later on, her aging mentor died. Around EC 325, Platonic attempted to steal a black crystal ball from Duke Demilamb and acquired the Association's layouts of the mansion. She infiltrated the home only to find the Duke's daughter extremely sick and was unable to complete the mission.[2]

Wine Glass HeistEdit

Chara img4C
After failing to steal the black crystal ball, Platonic returned to the Association's hideout in Beelzenia, where Bruno directed her to a new client, AB-CIR. AB-CIR hired her to steal a particular wine glass from Banica Conchita, offering to pay her enough money to buy her dream home. After receiving the mansion's floor plans, Platonic learned of the rumored white monsters roaming the area and that the allegedly cannibalistic Banica had only three staff in her employ.

The following evening she infiltrated the mansion, hiding once on the way to the treasure room when she came across the servants Arte and Pollo. With the twins seemingly gone, Platonic attempted to move on, only for Pollo to catch her. Shocked, she then saw Arte walk up holding a murara pig. While the twins argued over who would hold the pig for capturing her, Platonic broke free and created a smoke screen.

While the twins hunted for her, she fled and stumbled upon Banica's former cook, Ildebrando, the man having been crucified. Spying the wine glass on the nearby shelf, she grabbed it but accidentally spilled its contents, reanimating Ildebrando into a hideous, undead monster. As Platonic fled with the wine glass, she ran into Banica herself, who took it from her; following a brief battle, Platonic escaped to the garden and left the estate empty-handed.

She then traveled to Lioness and reported her to failure to AB-CIR at Castle Hedgehog's prison. One of the prisoners, Prince Carlos of Marlon, overheard their conversation;[3] once AB-CIR decided to have him infiltrate the mansion instead and changed his face with the Venom Sword, Platonic helped care for the unconscious prince until he was awake.[4]

Forcibly EmployedEdit

AB-CIR then assigned Platonic to steal the Twin Blades of Levianta from Elluka Clockworker instead.[5] Learning from Bruno about where Elluka was staying in Elphegort, Platonic drugged her tea and later crept into her room to find the swords. She was taken by surprise, however, by a sober Elluka, who ambushed and captured her;[6] after forcing Platonic to become her servant, she also discovered the thief's inability to cast spells. Elluka at one point kept her confined to their residence for a long period before coming back after remembering she'd left no food for her.[7]

In July, Elluka took Platonic before Empress Juno and bartered for her exoneration in exchange for helping her investigate Banica Conchita. While investigating one of the towns ravaged by undead monsters, Platonic recognized a caged one in the town as one of the white monsters that attacked her. Once Elluka extracted what information she could from the creature, they continued on towards the mansion. On the way there, they encountered the minstrel Xenos Jaakko, ignoring his warnings about approaching the mansion. When they arrived at the mansion in August, the estate was discovered empty and in perfect order. On the third floor, the pair discovered Banica's bloody wine glass and her child.

On the way back from the mansion, Platonic escaped from Elluka with the wine glass and returned home to Calgaround, rejoining her aristocratic family. Two months later, her family was visited by Xenos Jaakko, although she failed to recall the man. Some time after, she delivered the wine glass to AB-CIR.[8] The girl later regained all her memories as Eve Moonlit and passed away, allowing the slumbering Demon of Sloth to regain consciousness.[9]


Centuries afterward, no records of Platonic's true identity survived, leaving only her birthplace and thief identity still recorded in history.[10] Xenos Jaakko later penned an unpopular song entitled "Platonic and the Wine Glass", and detailed his encounter with Platonic in his memoirs entitled "Evillious Travels", including an illustration of her.[11] Centuries later, during the EC 900s, a waiter of the Graveyard restaurant related stories of Platonic's involvement with AB-CIR, Elluka, and Banica before being arrested by the Dark Star Bureau.[12]

Long after her death, the Clockworker's Doll crafted a new persona and assumed the identity of Margarita Felix nearly 300 years later.[13] While investigating the tales of the Flower of the Plateau, Elluka Clockworker came across Xenos' Evillious Travels and his accounts of Platonic.[14] After investigating the incident, Elluka confirmed Eve Moonlit's connection to the phantom thief and her false life as the original daughter of Calgaround.[15]

Personality and TraitsEdit

"You do cruel things..."
"There was no helping it, was there? That girl tries to escape as soon as I look away."
―Held and Elluka[src]

Platonic was a free-spirited and energetic person, determined to live a full life as she pleased. Growing restless with the formal and rigid lifestyle of an aristocrat's daughter, she severed all ties with her past and fully embraced the way of thieves, living by her own rules.[16] Despite this, she continued to uphold religious tenants drilled into her since childhood, such as being a vegetarian. Coinciding with her free lifestyle, the girl dreamed of owning her own house and falling in love with a handsome man.[17] Despite her free-spirited nature, she eventually returned back to this aristocratic life after her experiences with Elluka.[18]

Although confident in her abilities, Platonic was against killing and refused to murder anyone,[19] especially high-ranking nobles for whom she could be executed. She also had a great degree of loyalty to her employers, willing to complete a job long after it was originally assigned, and never revealed her clients.[20] Similarly, she was not above deceit to get a job done.[21]

Skills and AbilitiesEdit

"How odd. That you have a stranger as a companion. Does she, perhaps, have some talent for sorcery?"
"She's wonderful––so wonderfully talentless."
―Held and Elluka[src]

Despite having come from a rich and cultured background, Platonic was able to have some success as a thief and fit well into the lifestyle and work required. Although working alone, Platonic's connections to the Association allowed her to be well informed on her targets and more easily break into homes and avoid their inhabitants. Due to being a incarnation of Eve Moonlit, Platonic was also resistant to demonic influences, making her ideal for AB-CIR's missions.[22] In spite of this ability, she herself had no magical talent and was unable to perform even simple spells.[23]

Character ConnectionsEdit

AB-CIR: One of Platonic's employers. Keeping a business relationship, Platonic accepted the man's job and stuck with the mission until it was completed.

Elluka Clockworker: A temporary associate and partner of Platonic. Having been bound to her for sometime, Platonic had no issue deceiving the sorceress and felt no loyalty to her, often attempting to escape at any opportunity. In addition to this, she showed signs of being afraid of the sorceress to some degree.

Eve Moonlit: Platonic's true self. Hypnotizing herself to believe she was truly the daughter of the Calgaround lord, Platonic had no awareness of the slumbering Eve within her and only retained the witch's memories upon her later death.


Conceptualization and OriginEdit

  • Her alias as "Platonic" refers to a nonphysical love or relationship and to be friendly; the name is likely a reference to her birthplace near Merrigod Plateau.
  • Platonic's original surname, Calgaround (カルガランド), may be a subtle reference to the English term "Merry-Go-Round" (メリーゴーランド); the song Madam Merry-Go-Round is also sung by Miku.
  • The romaji for Calgaround (karugarando) may also a reference to the Japanese adverb 軽 (karugaru), meaning "lightly, easily, or carelessly"; it is also a possible allusion to Platonic's being an incarnation of the Demon of Sloth.
  • Platonic's name is partially inspired by the name of her representative Vocaloid, Miku, with Platonic's romanization containing "ikku" in it, with the same pronunciation as "iku".
  • Her title "Phantom Thief" invokes the phantom thief archetype popular in media; known in Western media as a "lady thief", it refers to a thief of noble upbringing.
