Till

male, 28 years old, 178 cm.
Till is a 50/50 and average-built man with fair skin, teal eyes, and shaggy grey hair. On the side of his neck is the scars from the pistol shots in his neck.

He is wearing a black turtleneck, a white hoodie and a black jacket, as well as grey sweatpants and heavy black boots.

he was in ANAKT GARDEN's 50th class before he was saved.

Unlike most of the pet humans in ANAKT GARDEN, Till suffers lots of abuse from his guardian. It is implied that his rebellious nature made him a target for especially harsh punishment, as evidenced by the numerous bruises across his face in his introductory video.
Till fell for Mizi because of her looks and beautiful smile, and developed deeper feelings the more he got to know her. It is because of this adoration that Till dedicated himself to protecting her. Although he usually never approaches her directly, he is seen observing her from afar. Till's love for Mizi served as his motivation and coping mechanism for the abuse and hardship he endured, as he can be seen clutching the red flowers Mizi adores when receiving punishments.
Round 3 shows some of Till's backstory through the lens of Ivan. Till had chased after a flower crown made of Anakt artificial flowers, similar to ones that Mizi has made for Sua, and it drifted into a dark passageway, a restricted area that appeared to be an alien's residence. It's unknown what happened prior to Ivan's appearance, but Till is crumpled on the ground next to a stunned Mizi as the two are in the presence of ANAKT GARDEN's wagyein guard. However, instead of backing down in the face of danger, Till steadily stood back on his feet. This created a core memory for Ivan as it became the moment he became enamored with Till.
During a time where Till is locked up in solitary confinement, likely because of his rebelling that caused the punishment, Ivan takes him out of his restraints and leads him outside to escape ANAKT GARDEN. As meteors fall, Till is amazed by the sight he had never seen before. But before they could go any further, Till's hand slips from Ivan's. He makes the decision to return back to ANAKT GARDEN realizing he could not leave Mizi behind.

In Round 2, he sings "Unknown (Till The End...)" and strategically doesn't allow the other person to sing and even attacks his opponent to rob him of any chance of winning.
After the events of "All-in", Till is seen inside of a karaoke room with his guardian and other aliens. It's possible that this was a small gathering for potential sponsors. As he refuses to sing "MY CLEMATIS" for the aliens, his guardian, infuriated, walks up to Till and grabs his face and demands that he perform. He shoves Till down to the table, showing an article about Mizi who has gone missing from Alien Stage. Something in him snaps, and he lunges for the nearest alien and attacks him but is quickly subdued. Judging by the disappearance of the alien's clothing, it can be inferred that Till was most likely sexually assaulted. In a haze, Till creates a vision of Mizi and reaches out for her hand, probably hoping that her presence, even if not real, could save him. The aliens leave the room and put a gag on him, to which Ivan removes after finding Till.
In Round 6, he goes against Ivan. After the latter forcefully kissed and strangled him, the score shows Till beat him 89 to 70, setting him up for a final round against Luka.
In Round 7, the final round, he is up against Luka. The latter, like in Round 5 with Mizi, manipulates Till into remembering the events from the previous round, though he ends up hanging on once he sees that Mizi was alive and infiltrated the audience. However, unfortunately for Till, Luka's manipulation gets the better of him, resulting in Luka winning. Till seemingly ends up dying in Mizi's arms after the round ends.
However, during the events of Karma, while the stage is burning down, Mizi realizes he's alive by hearing his heartbeat and runs to a rebellion member, Isaac, imploring for the rebels to take him. Seven years after what was dubbed "The ALNST Tragedy", Till is shown as part of the rebels, rescuing pet human children and showing them the way to the rebellion.

Till became a full-fledged participant in the rebels. However, due to a deep injury, he could not speak for a long time and saw hallucinations involving the dead Ivan.
when he got better, about 8 years after the events on stage, he was able to perform the first full—fledged operation - he saved the children made from the genes of his friends from the museum built in honor of Alien Stage.
all these children look like him and his friends because they are made from their genes in incubators. There are about 7 of them and they are also living with the rebels now.

Anakt Garden is a music specialized kindergarten that helps the participants improve their musical literacy while practicing to take part in the Alien Stage competitions.
Anakt Garden has the best music education system and the highest survival rates. Despite its school-like façade, it functions as a training facility to produce ALIEN STAGE champions, conducting cruel experiments to create exceptional pet-humans. Anakt's educational approach utilizes a cult-like system to brainwash the children, teaching them believe in the "Great Anakt", a false deity. Children are instructed to put their hands together and sing every day with vacant eyes.
Students who receive good grades on all subjects and maintain good conduct are nominated by their teachers and peers for the "Outstanding Student Award Ceremony". These students are then interviewed by Andromeda Media.
Class subjects include Music Appreciation and Interpretation, Religion and Music, and Expression of Music. Expression of Music is known to be infamously difficult. Anakt Garden also holds events for the children, such as athletic field events and a singing competition.
The experiments utilizes advanced technology to help train the students and to monitor the children's vital signs. These includes:
Dance practice - Dancing training using special equipment for precise monitoring.
Instrument practice - Observes how the human brainwaves react and change while playing instruments.
Image-making training - The students are tied to an operating chair, undergoing correction of smile and posture.
Singing training - Vocal training with the children hooked to special equipment.
Superiority test - Encased in a liquid tank, the process analyze the students to determine physical and intellectual genes that are classified as superior.
Heart rate variability - A rigorous training method exclusive to Luka, involving controlling heartbeats to induce the fear of death.

The Alien Stage is a televised singing competition hosted by the Segyein, where their Human Pets perform musical numbers for a panel of alien judges and a vast extraterrestial audience. The stakes are absolute: losers are executed on the spot, while winners are granted temporary reprieve and the opportunity to advance to the next round. The ultimate prize other than survival is unclear, but it's speculated that it could be a form of ambiguous "freedom" or elevated status within the segyein-controlled society.
For the segyein, the Alien Stage appears to serve multiple purposes. It is a form of public entertainment, which appears to sate the segyein's morbid fascination with human suffering, emotions and creativity. It may also serve as a way to reinforce segyein dominance, to discourage rebellion, and perhaps a perverse form of population control. For humans, it could serve as a twisted outlet for human ambition.
The Alien Stage competition is a potent vehicle for exploring several themes within the series:

Survival and desperation is the most overt theme, as every performance is a fight for life. As such, the competition often brings out both the best and worst in contestants, leading to complex and sometimes destructive relationships.
It highlights the exploitation of the subjugated human race for the entertainment of their oppressors. Some interpretations also suggest that the Alien Stage serves as an allegory for the cutthroat, high-pressure world of the k-pop and idol industries, where performers are pushed to extreme limits for public consumption.
It questions the nature of performance and the ethics of art when created under duress, and how genuine emotion can be co-opted for entertainment.
The competition is a form of entertainment for the Segyein, who find human emotion and talent fascinating. They force humans to compete for their lives and freedom.
The performances take place on a large, floating platform in a stadium-like arena, with the Segyein watching

male, died in 22 when lost to Till on purpose. As a child Ivan appeared quiet and off-putting, due to being raised in the slums and not knowing proper social behaviors. His fascination with Till started during this time, but the two of them often got into fights due to Ivan often saying things and behaving in ways that upset Till. Ivan put effort into appearing more normal, in ways such as practicing his smile in the Anakt Garden pond.
Later on in life, Ivan succeeded in appearing more normal as he adopted a cheerful persona and learned how to smile and be friendly around others. Classmates saw him as "too perfect to get close to", but he did manage to become friends with Mizi.
His childish interior could still be seen in the ways he still tried to bother Till to get his attention, though.
Beneath both the off-putting exterior of Ivan as a child and his cheerful nature as he grew up lays a deep sorrow and fatalistic view of the world, however. His two solo songs generally depict him as someone who believes he's destined for nothing but unhappiness, and that no amount of trying will ever change that. This is clearest when looking at his interactions with Till, as though Ivan is quite obsessed with him, he seems to be resigned in the fact that Till doesn't feel the same.
He's notably quite hypocritical, berating Sua for sacrificing herself for Mizi yet doing the same for Till, and also not following most of the tips he gives for his classmates in Anakt Garden in his student interview like not eating regular meals.

alive and living as a star forcefully.
male, 37, While he appears princely and charismatic on stage, Luka is determined when it comes to the pursuit of his goals, and is revealed to be ruthless, manipulative, and cunning, going so far as to exploit Mizi's grief over Sua's death in order to undermine her performance during Round 5, and repeating the same technique with Till, using Ivan's death against him during the final round.

While Luka mostly keeps to himself and rarely displays any form of genuine emotion offstage, he is shown to brighten up and become overwhelmed with emotion whenever Hyuna is present as he displays feelings for her and was close with her in the past.

Died in the age of 29. female.
In a now-deleted tweet, VIVINOS mentioned that Mizi was the most outgoing participant and always carried a positive attitude. However, it has been noted that she finds it difficult to hide her true emotions and struggles with being dishonest. This is apparent in the final scene of "MY CLEMATIS", where she visibly expresses her distress after witnessing Sua's death.

Additionally, it was originally thought that Mizi was raised in a favorable environment, which may have contributed to her initially believed obliviousness towards the darker aspects of the world around her.
However, in a new comic released on June 6th, 2025, “The True Face”, it is revealed that Mizi’s naive and cheerful personality was actually a persona, and it is shown that she deals with toxic positivity, which most likely comes from the toxic and neglectful environment created by her owners. Yet, it is implied that she still is happier than most in ANAKT GARDEN.

She is very bright and caring, and most people, notably men, in ANAKT GARDEN seem to admire her, which she is painfully aware of.

female, died in the age of 23.
In a now deleted tweet, VIVINOS describes Sua as one of the more elusive participants, as she rarely interacts with anyone other than Mizi. Sua is overly indifferent to others and is quite cold, with a sinister mentality and evasive tendencies. Sua can also become possessive over Mizi, getting annoyed with Ivan when he got too close to her, and feeling a general sense of irritation towards Till because of his crush on Mizi. Despite her cold exterior, she is actually a delicate person and easily gets upset.[7][8] Sua also has a kind and pure heart, though she never opened up to anyone other than her sister and Mizi, for fear of being hurt.

Isaac is a fairly tall man with brown eyes, short, dark brown hair and a scar running along his face starting from the the top right of his forehead to the left side of his cheek. He typically wears a plain black baseball cap, a black hoodie, black jeans and occasionally a jacket during missions. In All-In, he is seen wearing white sneakers.
Isaac is a loyal and trustworthy individual, often seen as an "older brother figure" to Dewey, which highlights his protective and supportive nature. He is a key member of the Rebellion, and his actions are guided by a strong moral compass and a commitment to the cause of fighting the Segyein. Unlike some of the other characters who are driven by personal feelings, Isaac is practical and grounded. shows his empathy and loyalty, proving that he is a reliable and caring individual who is willing to help those in need, regardless of the circumstances. Isaac is weak to human vulnerability, which affects his actions, sometimes selflessly. This is seen in an official artwork when he refuses to adopt Dewey because he already has too many children to take care of, when he is a teen himself, but took him in anyway, or when his opinion of Hyuna changed once Jacob told him about her struggles in a comic. Isaac can have a sassy attitude/short temper at times which is seen in the "Our Diva" comic where he makes several comments that show attitude towards both Jacob or Hyuna. He is more introverted than Dewey and needs time to let his guards down before trusting someone. He is at first resistant to Hyuna's jokes despite having a sense of humour himself, seen by teasing Dewey during their game of "Helli Gelli". He is not confident in his leadership. This is shown in "Our Diva" when Jacob leaves on a mission and Isaac has to temporarily take over. This comic also shows that Isaac thinks greatly of his older brother by the way he talks about his accomplishments. This causes Isaac to compare himself to his brother in a negative light
