"My name is Sixth Venom— . I hast taken out Elluka Clockworker at the Calgaround Mayor's home."
―Gatt Coulomb[src]

Gatt Coulomb, codenamed Sixth Venom, was the lieutenant general of Asmodean and a member of Père Noël. Subordinate to First Santa Claus and her apprentice Fourth Shadow, Gatt served the latter in the organization's operations in Elphegort. After Shadow's demise and Venom's failed assassination attempt of Elluka Clockworker, he returned to Santa's service.


Early LifeEdit

"I am bound by the limits of my blood. Asmodean runs rampant with authoritarianism far outclassing Lucifenia. I ought be merely satisfied with having the position I do now notwithstanding my being the son of a prostitute."

Born in Asmodean sometime during the 6th century EC as the son of a prostitute, Gatt learned he was the great-grandson of the infamous mercenary Gast Venom and a fellow descendant of the infamous Duke Sateriasis Venomania, facing severe discrimination by the authoritarian nation. He later joined the military and became a lieutenant general.[1]

During his service, he met Lucifenian Senator Julia Abelard and learned she was a mage seeking the vessels of sin, who had plans to destroy the gods and everything they created for a new world;[2] He also learned about her history with Elluka Clockworker.[3] Offered to join her criminal organization Père Noël to assist in her plans, Gatt accepted and received the codename "Sixth Venom", becoming the personal agent for his new master, "First Santa Claus".[4]

Over the years, he worked as a clean-up crew for the organization's dealings. During the period, he repeatedly met with Julia's adopted son, Lemy, and also met Julia's apprentice and fake sister, Mayrana Blossom.[1] After Fifth Pierrot was shot and killed by the world police in EC 607,[5] Julia assigned him as the interim assassin of the organization and he completed numerous murder missions for Père Noël.[6]

Internal ConspiracyEdit

"I've been asked for a little work by the president's sister."
―Gatt regarding Mayrana Blossom[src]

In December of EC 608, First Santa Claus ordered Gatt to retrieve the Venom Sword from Seventh Magician, giving him Grim the End to assure he could properly kill the demon contractor. After transforming the golden key into a knife, Gatt traveled to Seventh Magician's shop in Rollam on a snowy evening; after Yuzette allowed him inside, he told her honestly about his business there and how she had become a loose end for Julia. He then warned Yuzette he would come back the next morning, giving her a window of escape, and left.

The next morning, he returned to the shop to find Yuzette had fled.[7] After reporting his failure to First Santa Claus, Gatt continued his investigation into Seventh Magician's whereabouts.[8] Later, after Julia was successfully elected as the Lucifenian President in August, Gatt was assigned as the Asmodean prime minister's bodyguard for her upcoming presidential inauguration.[1]

Around that time he met with Mayrana, who had her face changed by Seventh Magician to look identical to Julia and took on her name as Mayor of Calgaround; she revealed that Second Dealer had been pocketing Père Noël's black market profits for himself, instead of supporting their operation to monopolize a cure for a manufactured epidemic in Toragay. Mayrana also related that the hypnotized Clockworker's Doll, Third Sleep Princess, was given the Gift poison to handle creating the epidemic and presumably kill her traitorous husband.

Gatt learned that Mayrana planned to send Elluka Clockworker, disguised as the newspaper reporter "Hanne Lorre," on a wild goose chase to learn the truth about Third Sleep Princess and their operation before finally killing her. Realizing Mayrana was jealous of Julia's obsession with Elluka,[3] Gatt agreed to help with the plot and decided to join her at Elphegort's Calgaround once he finished his upcoming duties and could go on vacation for it.[9]

On August 18, Gatt escorted the prime minister to Rolled and attended the ceremony in Milanais Square. During Julia's speech, the army commander joined the common crowd and spotted Lemy among them; greeting the child, Gatt fell to talking with him and explained his current assignment. The two ended up briefly discussing his position in the military and the discrimination he faced for his lineage before Julia finished her speech. After mentioning to Lemy his intention to take a ten day vacation to Calgaround for Julia's "sister," Gatt bid the child farewell and returned to the prime minister, agreeing to say hello to Mayrana for Lemy.[1]

Meeting with the ReporterEdit

Once Gatt escorted the prime minister back to Asmodean the next day, he took his vacation and traveled to Calgaround.[9] Meeting up with Fourth Shadow, Mayrana ordered him to pose as the local librarian to help direct "Hanne Lorre" to Toragay when she came asking about the "Flower of the Plateau", Mikulia Calgaround. Purchasing the original copy of the Freezis Fairy Tale "Flower of the Plateau" from Second Dealer,[10] Gatt disguised himself with a cloth over his head and awaited Elluka's visit on August 30.

Finding the disguised Elluka staring at the portrait of Mikulia and Gilbert Calgaround, Gatt greeted "Hanne" and introduced himself as the librarian, explaining he had been told by the mayor of her interest in the Flower of the Plateau. He then allowed her to look through the old vaults for information on the subject, leaving the "Flower of the Plateau" book on the counter for her to find when she returned. He was then interrupted from cleaning when Hanne burst into his office with the book and grabbed him by the collar, demanding to know where he'd received it.

Acting confused and afraid, Gatt listened as Hanne declared that all original works of Yukina Freezis had to be immediately reported to the Freezis Foundation and insinuated that he had illegally purchased the text. As she threatened to report him to the World Police, Gatt admitted he had his tracks covered by Père Noël, shocking Hanne. Pressed by the reporter, Gatt "confessed" to her that he had met with a man in Toragay claiming to be the leader of Père Noël, saying he had blue hair and a mask. With Hanne thus misdirected, Gatt escaped out the window.[10] He then returned to Mayrana's mansion and reported his success to her.[4]


"Please wait. It's mine job to dispose of her—"
"Silence, Venom! She's been gone for almost a year now—and yet you haven't produced any results."
―Sixth Venom and First Santa Claus[src]

Afterward, Gatt returned to Asmodean and continued his military service, tracking Seventh Magician to being a prostitute in Rolled during this time. He was later assigned the mission to assassinate Ton Corpa, with the scandal erupting over the diva he managed, Rin Chan, having the potential to cause issues for Père Noël. During the early morning of October 6, Gatt infiltrated the Corpa Mansion in Rolled only to discover the businessman had already been murdered.

After an employee confirmed witnessing someone in a clown costume fleeing south with Rin Chan, Gatt reported his findings to Julia and she deduced the missing Lemy had gone off to save the girl from Ton's alleged abuse and killed him. After Julia left for Elphegort and retrieved Lemy from Mayrana's mansion, Gatt visited the Abelard estate in Rolled and listened in while First Santa Claus congratulated Lemy on his first success as "Fifth Pierrot" from the adjacent room. He was then summoned to join the two as "Sixth Venom," to Lemy's surprise.

Gatt then watched while Julia described their criminal organization and how they'd originally planned to kill Ton. When she suddenly related she wanted Lemy to kill Seventh Magician, Gatt interjected that it was his job, only to be quieted when Santa snapped that he hadn't produced results for nearly a year. Gatt awkwardly reported his findings and his belief that Magician had changed her face with the Venom Sword. He then was forced to allow Lemy to join Père Noël and complete the murder mission.[8]

Outcome of ConspiracyEdit

"—Well, how went the doll’s retrieval?"
"It…has unfortunately come to naught. After I wounded Elluka I went to her very location with intent to retrieve her—But she had already vanished."
―Julia and Gatt[src]

After Julia had discovered what transpired between Kaspar, Mayrana, and Margarita, Gatt was sent back to Mayrana's mansion to retrieve the Clockworker's Doll while Julia had the Freezis Foundation's Bruno Marlon quarantine Margarita's epidemic. Arriving on October 21, he witnessed Margarita Blankenheim arrive at the mansion to continue her production of the Seventh Gift on the second floor while Fourth Shadow prepared for Elluka's expected arrival.

Gatt later hid in the mansion while Mayrana confronted Elluka and her apprentice Gumillia, watching as Mayrana was defeated by the latter. After the mage duo confronted Margarita upstairs and brought Rin Chan up from the basement, Gatt took advantage of Elluka being deep in thought to run up and impale her on his sword. He then swiftly removed his sword from Elluka's body and deflected Gumillia's gunfire; announcing his codename and his triumph over Elluka, Gatt fled upstairs to retrieve the Sleep Princess' body,[3] only to find that the Clockworker's Doll was already gone.

Afterward, Sixth Venom reported what transpired to First Santa Claus and then began cleaning up the evidence of their actions in Elphegort over the next month. During the period, he suppressed any reports of Mayrana's death in the newspapers, preventing even one article from being written on her.[3] He then tracked Rin Chan to Aceid and moved her in with the sister of Julia's maid Phoebe to keep her in hiding.[8] Around mid-November, Gatt confirmed eye witness reports that Elluka was recently spotted with her apprentice in Toragay.[5]

Gatt then traveled to Rolled to report to First Santa Claus, arriving at the Abelard state on the morning of November 26. Asked about the post-processing in Elphegort, Gatt reported his activities, including his failure to kill Elluka; he was then shocked when the furious Julia berated him over all the liberties he and Mayrana had taken, which had cost her Mayrana, Kaspar, and Margarita as pawns.

He furthermore learned that, in spite of Mayrana's own jealousy, Julia hadn't even wanted Elluka killed, as she wished to kill the mage herself. Chastised and slapped by his superior, Gatt more meekly discussed her plans to make Bruno her new Marlon pawn before preparing to leave. As he did, Julia ordered him to weed her garden and, although shocked, Gatt reluctantly agreed under threat of death. After saying farewell to his superior, Gatt weeded Julia's garden.[3]

Scandal and DeclineEdit

"Sixth VenomYou shouldn't underestimate him. At least he isn't your enemy for now. Besides, he's great at sneaking into enemy territory. He'll be killing Bruno quite soon, don't you think?"
―Elluka to Lemy[src]

Once Lemy successfully killed Yuzette Ora on February 11, the young Fifth Pierrot continued handling assassination missions in place of Sixth Venom.[5] After the new Second Dealer Bruno was captured and scandals erupted over Julia's involvement with him, First Santa Claus ordered Gatt to help Lemy kill the new Seventh Magician and Eighth Sniper on September 2, having learned from the boy that the two members were actually Elluka and Gumillia. With Lemy having arranged to meet with the two beforehand, Gatt accompanied Lemy to their base at Rolled's whorehouse to ambush them.

That evening, he infiltrated the whorehouse from the back while Fifth Pierrot entered the front, only for the two to find it abandoned. Reconvening with Lemy, Gatt suggested that Elluka had sensed they were coming to kill her and fled; as he comforted the disappointed boy, he shared his own experience with trying to kill Elluka and being punished for it.[11] Later that month, on Julia's orders, Gatt infiltrated Castle Hedgehog in Marlon where Bruno was being tortured for information on Père Noël, swiftly assassinating him with his sword before escaping.[12]

After Lemy was killed by Elluka and Gumillia and Julia resigned the presidency, Gatt joined First Santa Claus in hiding from the World Police at Elphegort's Merrigod Plateau. Taking Grim the End again and transforming it into a sword, Gatt traveled outside the city limits of Calgaround and waited until Elluka and Gumillia's approached on January 29 in horse-drawn carriage. He then challenged them in the middle of the road, firing a blast from his weapon and beheading their horse. As the carriage crashed before him, he admired his work and confronted Elluka and Gumillia as they came out of the carriage.

His loyalties questioned, Gatt asserted his belief in Julia's cause against Elluka's criticisms. He then declared his intention to avenge Lemy, remaining determined on this point despite Elluka's attempts to hypnotize him from his goal. As he angrily tried to put their battle to an end, Elluka cast a spell and electrocuted Gatt with a myriad of lightning. Charred and unconscious, Gatt was tied to a nearby tree and left for the World Police; he was soon after captured and imprisoned at their Elphegort detention center,[13] interrogated by the police organization.[14]

Personality and TraitsEdit

"Gatt Coulomb. Why have you sworn so much loyalty to her?"
"It is for justice. There are necessary evils one must undertake to right this world.
"…So you’re rampaging out of a sense of justice. How naïve. Your ancestor thought like that too, but in truth he just had an uncontrollable personality."
―Elluka and Gatt[src]

Gatt was a coldblooded and disciplined individual tempered by his sense of honor. Straight-forward and largely dependable, Gatt took action when he believed necessary and reported his failures with humility.[3] He similarly conducted himself in a formal, orderly manner in Père Noël, dispassionate and coldblooded in his approach to murder and respectful of his superiors.[4] He wasn't above insubordination, however, sometimes speaking his mind or even complaining about his job, but he was quick to fall back in line under threats from First Santa Claus in particular.[3]

In contrast, Gatt was enamored with the power given to him by wielding Grim the End and arrogant in his own abilities.[13] He also approached his official role as a lieutenant general rather liberally, knowing he could never be promoted to a proper general due to his lineage to Venomania and Gast Venom. As such, he was disillusioned with the current state of the world and believed heavily in Julia Abelard's message that Père Noël sought to benefit it, believing the ends justified the means to "correct" the world.

Developing strong convictions to his own sense of honor, Gatt was thus extremely loyal to Julia.[13] This loyalty extended to the rest of Gatt's comrades in Père Noël, showing a limited mercy even to those Julia sought to dispose of.[7] Likewise, he felt a sense to avenge his fallen comrades and ruthlessly eliminated Père Noël's enemies and known traitors. As part of his honor, he disapproved of his enemy's "cowardly" methods of killing their comrades,[13] though largely employing those same methods for his own assassinations.[4]

While posing as Calgaround's local librarian, Gatt portrayed himself as a meeker and more innocent persona, portraying himself as affable but also dramatic. As a habit, Gatt commonly wore a cloth over his face to mask his identity while taking part in an operation.[10] He likewise spoke in a peculiar Asmodean regional dialect.[4]

Skills and AbilitiesEdit

As a trained soldier, Gatt had considerable speed and agility, able to dodge gunfire with ease. He was similarly gifted with swordplay and was capable of effectively wielding a longsword.[4] This prowess extended to his use of Grim the End, able to utilize the vessel of sin as either a dagger or his preferred longsword when needed.[13] Gatt therefore had an expertise in assassination, able to remain hidden and undetected when hiding or sneaking up on a target.[4] Despite his lineage, Gatt's skills allowed him to become the second-in-command of the Asmodean armed forces.[1] Sixth Venom was also a competent liar, though a bit overdramatic when maintaining a facade.[10]

Character ConnectionsEdit

Julia Abelard: Gatt's superior in Père Noël. Gatt was loyal to Julia as his superior, and while he occasionally talked back to her in defense of himself or other subordinates, he feared her wrath and never disobeyed a direct order, no matter how trivial. He additionally believed wholeheartedly in First Santa's rhetoric that Père Noël was making the world a better place, despite her illegal activities.

Elluka Clockworker: One of Gatt's targets while under Mayrana. Gatt was aware of the jealousy that Elluka inspired in his fellow member and enjoyed taunting her along with Mayrana, proudly exclaiming how he had killed the sorceress after stabbing her. He continued to serve as a thorn in her side over their other encounters, although underestimating her power as an enemy.

Lemy Abelard: One of Gatt's coworkers. Originally knowing him as Julia's son, Gatt got along well with Lemy and did not take any measures should expose him to the more unsavory aspects of his life or work. Following his introduction to Père Noël, Gatt continued to treat the boy amiably, comforting him when he was disappointed by Seventh Magicians escape. He was similarly angered by his apparent death at Eighth Sniper's hands.

Mayrana Blossom: A fellow member of Père Noël. Gatt worked closely with Mayrana during her time masquerading as Julia Abelard, and Gatt was close enough with her to understand her jealousy of Elluka because of Julia's obsession with the mage, and dutifully followed out her wishes.


Conceptualization and OriginsEdit

  • Gatt's name is partially inspired by his representative Vocaloid, Camui Gackpo, with both names sharing their first two letters.
  • In the Fifth Pierrot PV, Gatt is labeled as さむらい, referring to a "warrior" or "samurai", a possible reference to his occupation as a soldier and Gackpo's samurai aesthetic.
  • Gatt's antiquated way of speaking may be a reference to the archaic dialect typically associated with samurai in literature.
  • Gatt's surname may be derived from the coulomb, a unit of electric charge used in science.


  • Gatt is given "chores" as his description in the Fifth Pierrot PV; humorously, in Evil Food Eater Conchita, the Vocaloid Gackpo is credited as the "choreman" for the song while Gammon Octo, a former USE soldier, is made the "choreman" of Evil's Theater.
  • While providing the first design of Gatt in Evillious media, Tamara confirmed that it was purely her own fake appearance for him and was not his official design;[15] a completely new official design was illustrated by Ichika for the Fifth Pierrot light novel released several months later.
