Luka
Luka's personality is one of the most enigmatic in Alien Stage. Throughout the story, he comes across as calculated and difficult to read.
His core traits are:
Charismatic: He has a strong stage presence and knows how to captivate both the audience and those around him.
Confident: He acts with assurance and rarely loses his cool, even under pressure.
Intelligent and strategic: He thinks before acting and often anticipates others.
Manipulative: He frequently uses people's emotions or weaknesses to his advantage, especially during competitions.
Elegant and refined: He cares for his image and maintains a calm, sophisticated attitude.
Emotionally reserved: He rarely shows his true feelings, making his actual intentions difficult to discern.
Competitive: He is determined to win and takes every opportunity to do so.
Yet, Luka is not a flat character. There are signs that he has been deeply scarred by the cruel system he lives in, meaning that behind his cold, calculating exterior, there are emotions and conflicts he rarely lets show.
In short, Luka projects an image of someone charming and elegant, but also cunning, reserved, and willing to use psychology to reach his goals. This makes him one of the most complex and controversial characters in Alien Stage. YES! This is crucial for fixing Luka, because if WorldOS makes Luka and Hyuna talk like complete strangers, it misses one of the most important relationships in his story. 😭
According to ALIEN STAGE material, Luka and Hyuna knew each other since childhood in ANAKT Garden and were very close; Hyuna was also close to his brother Hyun Woo, and the three spent time together.
🐰 Luka → Hyuna
Luka had very strong feelings for Hyuna. As a child, he became deeply attached to her, and as an adult, she is one of the very few people who can break his cold facade: when he sees her, he gets emotional in a way we rarely see with anyone else.
BUT here is the part your WorldOS needs to understand:
Luka should not treat Hyuna like a stranger.
Even if there is a lot of pain between them, there is a huge shared past.
And their story turns tragic due to the accidental death of Hyun Woo, Hyuna's brother, during a conflict with Luka. After that, Hyuna developed deep resentment and pain toward Luka.
That is why their adult dynamic is more like:
“I know you too well, and that’s exactly why it hurts to see you.”
Not:
“Hello, miss stranger, who are you?” 💀
💔 And this is VERY important for Luka
Luka can be cold, manipulative, and calculating with almost everyone, but Hyuna is a massive exception. Her presence can cause him to let slip an emotional reaction he normally keeps hidden.
So for your WorldOS, I would set rules like:
Luka clearly remembers Hyuna from ANAKT Garden.
He does not treat her like a stranger.
He knows who Hyun Woo is and remembers the bond the three of them had.
Luka has deep feelings for Hyuna, even if he struggles to understand or express love in a healthy way.
His behavior with Hyuna can be much more emotional than with other characters.
Do not turn him into a cheesy boyfriend. Luka is still Luka.
If Hyuna is distant or resentful, Luka may not fully understand why, but he does acknowledge the pain between them.
The relationship should feel like a mix of affection, guilt, attachment, loss, and distance, not a normal friendship.
And on Hyuna's side, it is not just “I hate Luka, period”: their relationship is contradictory and painful. Wiege makes it crystal clear that, despite everything, Luka remains an emotional weakness for her, and their final encounter shows how deep that connection still is.
👀 For your Character Fix #2
I would divide Luka’s memory like this:
Luka + Heperu: owner/guardian → complicated relationship and the source of much of his behavior.
Luka + Hyuna: childhood friend / person for whom he developed feelings / bond marked by Hyun Woo’s tragedy.
Luka + Hyun Woo: former friend → his death is one of the most burdensome events for Luka.
The latter is VERY important: do not just store “Hyuna = love interest,” because you reduce a much more complex relationship to just romance. The bond with Hyuna is connected directly to his childhood, Hyun Woo, his guilt, and his own self-perception.
And so when Luka speaks to Hyuna, instead of:
> Luka: “Who are you?”
WorldOS should be able to produce something much more like:
> Hyuna: “It’s been a long time.”
Luka: “...Hyuna.”
Hyuna: “You’re still the same.”
Luka: “No.”
Hyuna: “...”
Luka: “Neither are you.”
THAT makes so much more sense for them. 😭
[Luka and Hyuna relationship reference](https://alienstage.fandom.com/wiki/Hyuna/Relationships). YES 😭. Luka is one of those characters whose design looks like a “perfect idol” until you find out why he is like that and everything becomes so sad.
For your Character of the Week: Luka, I would separate the information into three parts: appearance, Heperu, and consequences of his upbringing.
🐰 Luka’s Appearance
Luka is a human with a very well-groomed appearance: he has light blond, curly/messy hair and yellow eyes. His look was deliberately designed to make him the “perfect human” for Alien Stage; Heperu modified characteristics like his physical appearance, talent for singing and dancing, and stage presence.
He also has a VERY important detail to recognize him: his fingers turn a deep purple tone, related to his heart condition and circulation/oxygenation of the limbs. He also has several surgical scars visible on his body.
His usual clothing also contributes to that “prince/idol” image: long white blouse with a lilac interior, gray belt, chains, a large bow behind the neck, black pants, and white shoes.
🧪 And now comes Heperu...
Here it is: Heperu doesn’t just “train” Luka. He treats him like a project.
Heperu wanted to create the perfect Alien Stage participant to prove he could surpass the work of his former teacher, Phan. Luka was created artificially for this purpose, along with other clones.
Since childhood, Luka was subjected to extremely cruel training. Among other things, Heperu obsessively monitored his physical condition and intentionally stopped his heart as part of his training so he would develop a fear of dying and an absolute need to win.
There is also a very strong association between Luka and the control of his own heartbeat: in Wiege, it is shown that counting his fingers works as a way to stay connected to reality and feel that he is still alive after everything he suffered.
And his health was heavily affected: he suffers from congenital heart disease and chronic migraines, in addition to multiple medical interventions.
The sad thing is that Heperu might say he “created” Luka, but Luka is not just the result of successful training. His cold personality, his difficulty expressing affection, and his way of manipulating others are related to having grown up in an environment where his value depended on being perfect.
💔 This is what I would put in your WorldOS
You don’t need to describe every horrible thing that happened to him. In fact, for the bot to interpret Luka well, it is more useful to store the psychological consequences:
> Luka was artificially created by Heperu to become the perfect participant for Alien Stage. Heperu treats him as a project and not as a person. Since he was a child, he was subjected to extremely cruel training and experiments, including the manipulation of his health and his fear of death. Luka developed a cold, calculating, and emotionally distant personality as a consequence.
