―Gammon Octo[src]

Gammon Octo, also known as the Cursed Gardener, was a USE soldier, the leader of the Tasan Party, and a descendant of Sateriasis Venomania. Losing his brother to Gallerian Marlon's misjustice, Gammon formed the anti-government organization in opposition to the blatant corruption. Years later, he came to Evil's Theater in search of the Venom Sword. Captured and nearly put to death, he was saved by the Waiter and became a choreman for the theater inhabitants.


Early LifeEdit

"Then... could you return that sword, at least that sword? It's been passed down through our family, it's a treasured heirloom!"
―Gammon asking Gallerian Marlon for the Venom Sword[src]

Gammon was born a member of the Octo Family and the younger brother of Nyoze in the Union State of Evillious sometime during the EC 900s, living in Levianta's Samadin region. Later on, Gammon became a sergeant general in the Leviantan military.[1] In EC 978, Nyoze was framed and convicted for the murder of Medea Col by the Dark Star Bureau Director Gallerian Marlon.[2] After Nyoze's trial, Gammon quit the military.[3]

He then attempted to set up a meeting with the judge for several days. Unsuccessful each time, Gammon traveled to Gallerian's mansion that night, refusing to be sent away. After he pleaded with Gallerian that Nyoze was innocent, the judge threatened him with the ramifications of his words and he silently listened to his reasoning for Nyoze's guilty verdict. Gammon then tried to at least retake the Venom Sword from Gallerian's custody and failed, Gallerian forcing him to leave after.[4] Embittered, Gammon became president of the Tasan Party.[5]

For JusticeEdit

After Nyoze escaped and became a fugitive, Gammon kept contact with him while he lived in Rolled under the name of one of Gammon's subordinates, "Shakuson". As president of the Tasan Party, Gammon began working tirelessly from both Levianta and Elphegort to put an end to Gallerian's corruption. Over time, he also began suffering from not having contact with the Venom Sword, understanding that whatever was inside the sword had acted upon him like a drug while it was in his family's possession. He also requested that the real Shakuson go by the name "Ben" from then on.

In EC 982, Gammon began looking into Nemesis Sudou, the perpetrator of several killings in Rolled and Nyoze's friend, by Nyoze's own request. Obtaining documents from Gallerian's aide Bruno Zero, detailing among other things Gallerian Marlon's history with the playwright "Kayo Sudou", Gammon discovered that Nemesis was Gallerian's illegitimate daughter and an assassin for the Dark Star Court's secret espionage force, PN. He subsequently wrote a letter to Nyoze keeping him updated on current events, as well as suggesting he continue observing Nemesis as she could be key to taking down Gallerian.[6]

When Gammon received a reply from Nyoze, his brother had stated his refusal to use Nemesis; furthermore, Nyoze instructed him not to hurt her if she ended up shooting him for her employers. After Nemesis shot Nyoze in December of EC 982, Gammon had her tracked as she fled to Retasan and then had her abducted from her hotel room. In private Gammon met and spoke with his brother's killer, learning that she had fled to avoid her employers, whom she now hated.

When Gammon brought up that one of them was her father, she asked for him to confirm this and he shared with her all that he had learned about Gallerian and Kayo Sudou. Gammon then began trying to convince Nemesis to join the Tasan Party once she initially refused. As he did, he covered a variety of topics with her and discussed the various objectives of the party, including ending the corrupt Dark Star Bureau, ending the war going on in Evillious, and stopping the discrimination of native Elphes in Elphegort.

As Nemesis continued to have doubts, Gammon espoused his philosophy of achieving justice even if one had to do bad things to do it; when the conversation turned back to Nyoze, he pointed out how he had refused to use her and wanted to save her until the very end. After this, Gammon successfully convinced Nemesis to join the party and take revenge on those like Gallerian, who had taken her loved ones from her.[7]

Levianta Civil WarEdit

The following year, Gammon attended Tony Ausdin's trial for the slaughter he instigated at Zenosai and the murder of Shiro Netsuma, observing as Gallerian give Tony a not-guilty verdict.[8] Not long after, he joined Nemesis at Shiro's grave and listened as she talked about her relationship with the woman, pointing out that Gallerian had betrayed her memory by his recent verdict. The two chatted for a time about the progress of the Tasan Party and the strange occurrences happening in the world; afterwards, Gammon had them leave the grave, explaining how the time for revolution was at hand with the disgruntled populace and soldiers.

Gammon also instructed Nemesis to take revenge by killing Tony and Gallerian, herself.[9] A month later, in August of EC 983, the Tasan Party instigated a civil war in Levianta led by Gammon Octo. During the fighting, Gammon led the militia to murder Jason Jack as their first victim, in retribution for his committing the murder that Nyoze was framed for.

Gammon's troops then targeted the corrupt official Bindi Freezis, only for Bindi to be smuggled out of Alicegrad. After USE soldiers were brought in to quell the riots, Gammon was able to turn the disgruntled soldiers onto the side of the militia due to his military background. On August 10th, Gammon and his men successfully captured the Dark Star Courthouse and arrested Bruno Zero.

Finding Gallerian had escaped,[10] Gammon had him tracked to his house; he and the militia surrounded the house and waited for Nemesis to arrive, instructed to let her handle Gallerian. While they waited, they were attacked by blue flames, which surrounded the mansion. After Nemesis arrived and asked about the fire, Gammon explained what had happened and watched as Nemesis seemingly began talking to herself over it. He then tried and failed to convince Nemesis to leave Gallerian to burn to death, only watching as she went inside and confronted him. Not long after, Nemesis shot and killed Gallerian as they'd agreed.[11]

Evil's TheaterEdit

"I carry this fearsome curse upon my body and, to undo the curse, the sword passed down from my ancestors was needed. I came to this forest, alone, to seek it."
―Gammon's "testimony"[src]

Following the Leviantan Civil War, Gammon reformed his organization as a political movement in Elphegort and the Tasan Party became immensely popular in the wake of Gallerian's downfall. When Nemesis' history in the criminal gang Zeus was discovered and she was sentenced to ten years imprisonment, Gammon used his influence to arrange a shortening of her sentence;[12] in EC 989, Nemesis was released from prison and rejoined the party, becoming elected as its vice leader below Gammon.[13]

Years later Gammon, still suffering from the "curse" of the Venom Sword's enchantment, left for Evil's Theater where Gallerian Marlon's fortune allegedly had been stored, hoping to find the Venom Sword there.[14] After he arrived at the theater, he managed to elude the Master of the Graveyard and her servants;[15] shortly after, he was trialed and sentenced to death by the Master of the Court.[16] As he awaited his execution, the Waiter stepped forward and recruited him to be their choreman. With few other options, Gammon became the new "Gardener" of the theater, replacing the mage and playwright, Ma.[17]

Afterward, Gammon began cleaning up after the residents and doing any jobs they needed of him. He also began helping Ma with creating screenplays about various characters related to the Seven Deadly Sins for the theater. Using his Purple Dream ability, he was able to detail the lives of his ancestors to better understand his curse; using the experiences he envisioned, the Cursed Gardener was able to adapt numerous historical events into screenplays.[18]


Gammon explaining his reasons for coming to the theater

Around this time, he had a dream envisioning the Master of the Court's future should her utopia be realized.[19] Concerned about its relation to the world's destruction in EC 1000,[20] he wrote down his vision as one of the screenplays, although the other theater residents paid it no mind when showed the screenplay.[21] During his time there, Gammon learned that the Servants were merely copies of Hänsel and Gretel created from their remaining wills left in the Glass of Conchita.[22] He was also made the replacement for the unawakened vessel of Lust.[23]

In EC 998, Gammon attended the "trial" held by the Master of the Court, searching for the vessel of Wrath, annoyed they didn't just have a normal meeting.[24] During the assembly, he explained his need for the Venom Sword after being given permission by the Master of the Court.[25] Later, Gammon was tasked with organizing the court "motions" for the Master of the Court and he reviewed the cases while reflecting on what they learned from each story.[26]

World's EndEdit

Following the destruction of the Third Period in EC 999, Gammon was one of the many human souls trapped on the ground world as it merged with the Hellish Yard. As several former Tasan Party soldiers gathered at the floating Evil's Theater, Gammon addressed them at the center of the gathering.[27]

Personality and TraitsEdit

"I don't trust people who shout loudly about justice. How many of the weak have shed tears due to the shadow of worthless heroism?"
―Gammon's reaction to Red Shoe Parade[src]

Gammon was an individual embittered by his experiences. As a result of the corrupt climate of the USE, Gammon originally was instilled with a strong sense of justice which he took to extremes. Wanting to end the suffering in Levianta and Elphegort at any cost, Gammon espoused an ideal that the ends justified the means and that one should be willing to do bad deeds, even murder, if it meant protecting someone else or ending corruption.[28] Although seeming to take a more nuanced view of "justice" later, Gammon continued to despise corruption and,[29] at the world's end, espoused extreme methods to "save" it.[30]

Following his introduction to Evil's Theater, Gammon appeared more pessimistic, often sighing and despairing of the outcome of his or others' endeavors.[31] As part of this, through the use of his Purple Dream ability, Gammon became concerned about the outcome of collecting the Seven Deadly Sins,[32] believing that EC 1000 would herald the world's destruction.[33] He also became hostile to the idea of pointless and harmful heroics being justified with "justice", seemingly in spite of his attitudes in the Tasan Party.[34]

Despite these demeanors, Gammon was not distressed by how he had become used to living in the theater with the inhuman inhabitants, although sometimes exasperated by their strange natures.[35] He also considered himself different from humans,[36] possibly due to his being affected by the Venom Sword.[37] Gammon himself remained concerned with this "curse" and suffered as though from drug withdrawal without the presence of the sword.[38] Aside from this, he was interested in learning about his ancestry and origin using his prophetic ability.[39] He was also very observant, taking notes and formulating theories on all he learned while in the theater.[40]

Skills and AbilitiesEdit

"But occasionally there may be a prophetic dream. Thus, I write it down. I thought it might be useful for something."
―Excerpt from Gammon's writings[src]

Gammon was trained in the Union State of Evillious military, attaining the rank of Sergeant General,[41] and as leader of the Tasan Party he exerted great skills in management, charisma, military leadership, and investigation.[42] Besides this, he inherited his ancestor's prophetic dream ability he denominated as "Purple Dream", allowing him to dream events from either the past or future. His ability to peer into the past was assumed accurate, used to help construct the screenplays about past events with Ma.[43] However, his ability to see the future was often inaccurate, estimating his vision about the alleged utopia having less than a fifty percent chance of being correct.[44]

Although dubbed the "Gardener", Gammon's work at Evil's Theater ranged from tasks of choreman to that of a secretary, filing and organizing the transcripts for the Master of the Court's "court cases". He also had skills as a scriptwriter, collaborating with Ma in creating the screenplays of Evillious' past.[45] Because of his visions and collaboration with Ma, Gammon became very knowledgeable of Evillious' history with the Seven Deadly Sins, creating several theories about the different people he envisioned.[46]

Character ConnectionsEdit

Nyoze Octo: Gammon's brother. Gammon and Nyoze were close, with Gammon trusting Nyoze completely and becoming motivated to take down Gallerian in the wake of his brother's false conviction. As part of this closeness, Gammon utterly respected Nyoze's word, not killing Nemesis on his request despite her being his killer.

Nemesis Sudou: One of Gammon's partners. Although initially knowing her as his brother's killer, Gammon hoped to use Nemesis to bring down Gallerian and, as Nyoze additionally had loved Nemesis, spared her and sought to turn her against her former employers. The two worked closely together in the Tasan Party until Gammon's disappearance into Evil's Forest.

Gallerian Marlon: The man who condemned Gammon's brother. Following Gallerian's false conviction of Nyoze, Gammon became contemptuous of Gallerian's greed and corruption. As such, he became dedicated to bringing him down at any cost.

Master of the Graveyard: A fellow member of Evil's Theater. Gammon initially saw the Master of the Graveyard as an obstacle towards getting the Venom Sword and eluded her. After becoming the Gardener, Gammon cohabited with her as with the rest of the inhabitants of Evil's Theater and was particularly curious about the nature of her Servants.

Master of the Court: A fellow member of Evil's Theater. Gammon acknowledged it was only her naivete and not real malice that allowed her to be manipulated into executing visitors, but disagreed with her idea of Utopia. In addition, he was exasperated with her adherence to trials rather than regular meetings, although Gammon was not willing to face the Master of the Court's anger if he spoke on the matter.

Waiter: A fellow member of Evil's Theater. Gammon thought of her as a spoiled girl, understanding her selfish reasons for saving him. As the chore boy, he would do some of her work around the theater and was curious about her resemblance to the Female Servant.

Ma: A fellow member of Evil's Theater and the previous Gardener. Gammon got along with Ma well enough to help her with her screenplays using his Purple Dream ability, learning more about the past via their relationship. He also served as her employee, tending to her garden. Despite this, he disagreed with her theory that utopia would result from the sins being gathered.

Sateriasis Venomania: Gammon's distant ancestor. Gammon showed an interest in learning about his heritage since making his way into the theater, learning about him using his Purple Dreams.

Lukana Octo: Gammon's distant ancestor. She birthed the Octo line that would eventually come to Gammon.


Conceptualization and OriginEdit

  • One definition for the word "gammon" is to speak misleadingly or deceptively.
  • His surname is derived from the Greek and Roman prefix octo, meaning "eight".
  • Gammon's name is partially inspired by the name of his representative Vocaloid, Gackpo, with both names sharing the first two letters.


  • In Evil Food Eater Conchita, the Vocaloid Gackpo is credited as the "choreman" for the song, referencing Gammon's outcome as the Cursed Gardener;[47] similarly, one of Père Noël's members, Sixth Venom, was labeled as being used for "chores" in Fifth Pierrot.[48]
  • In the Evils Court booklet, Gammon does his job as a "clerk" via organizing the songs in the album and leaving his commentary for each "court case" from the Evils Court booklet.
  • Due to their lineage to Duke Venomania, both Gammon and Nyoze had the potential to develop Hereditary Evil Raiser Syndrome and pass it onto future generations.[49]
  • According to mothy in the Livestream of Evil, Gammon wears his hair over his eye for aesthetic purposes.
