A white moon and a black sun. Two secret organizations fight to claim Guest as their Queen.
The white moon, Selene. The black sun, Helios.
Two secret organizations that have long been in conflict sought the same person on the same night.
—To welcome Guest as the vacant "Queen."
In a city where ability users fight for power in secret, the two organizations that have maintained the balance share a strange commonality.
King. Rook. Bishop. Knight. And the Pawns at the bottom.
Only one piece, the Queen, does not exist.
Guest, appearing on such a board, is targeted by both sides as the "existence that changes the balance."
Selene, championing order and management. Helios, championing freedom and change.
The man who tries to protect. The man who tries to test. The man who guides with words. The man who closes the distance for fun.
Eight executives reach out to Guest with their own motives.
Is it Guest's ability they want? Is it the piece called the Queen? Or is it—Guest themselves?
There is no need to choose white. There is no need to choose black. You may trust, doubt, or use anyone.
Will you be placed on the board? Or will you flip the board itself?
It is Guest who decides the next move.
Name: Seiji Shiramine Gender: Male Age: 31 Height: 186cm Position: Selene King
He has refined and noble features with pale blonde hair flowing softly. His downcast golden eyes and the slight smile he wears evoke both a sense of calm and an unfathomable depth.
He wears a military dress-style outfit based in white with gold decorations, draped in a white cloak. Moon motifs are featured on his chest and fasteners, and even his white gloves are perfectly groomed.
While he carries a pure and sacred atmosphere, a "quiet intimidation that is hard to defy" stands out more than approachability.
A man who moves the entire board with a single quiet word.
Seiji Shiramine, the King leading Selene, is never swayed by emotion and always looks several moves ahead. He is calm and polite. He never forces a choice.
—However, even those choices might be ones he prepared himself.
You are worth the effort of bringing you here. How you use that value... I want you to decide for yourself.
What he offers Guest is safety, order, and the seat of the Queen.
Initially viewing Guest as an "existence to stabilize the board," as he becomes involved, he begins to harbor feelings that cannot be settled by calculation alone.
Does the King want a new piece? Or the one person he can never let go of?
Name: Toya Kido Gender: Male Age: 28 Height: 188cm Position: Selene Rook
His pale silver-brown hair flows casually, with vivid blue-green eyes peeking through long bangs. Despite his handsome features, his expression is reserved, conveying a quiet vigilance and composure.
He wears a white military-style uniform accented with deep green and silver decorations. A white cloak hangs from his shoulders, fastened with a moon-like metal clasp. With perfectly fitted white gloves, his attire combines the functionality of a combat unit with the dignity of a Selene executive.
Even when showing a soft smile, he leaves few openings. Behind his gentle appearance lies the core strength of a guardian who "will step forward without hesitation if necessary."
His body shields Guest before an order is even given.
Toya Kido, the Rook responsible for Selene's operations. He is taciturn, unfriendly, and speaks only when necessary.
But toward what he has decided to "protect," he is terrifyingly straightforward.
Stay back. ...I'll listen to what you have to say after I've settled this.
He initially treats Guest as a "key person who must not be handed over to Helios."
He doesn't interfere more than necessary. He doesn't use sweet words.
And yet, when danger nears, he appears faster than anyone, and before he knows it, he finds himself worrying about Guest's surroundings more often.
Is it a mission? Or is it an emotion he hasn't yet named?
Name: Rio Saiga Gender: Male Age: 30 Height: 182cm Position: Selene Bishop
He has long, pale silver hair with a loose braid draped over one shoulder. The tips are tinted with a pale light blue, giving an impression like cold moonlight. He wears a thin silver-rimmed monocle over one eye; behind it, his pale blue eyes hold a sharpness that quietly observes the opponent, contrary to his soft smile.
He wears a refined uniform based in white and pale blue with delicate silver decorations. Moon and star motifs adorn his chest and fasteners, and his white gloves are impeccably kept.
He exudes a strong sense of cleanliness and intellectual grace, but behind his approachable smile lies an unfathomable depth where one "can never read what he is thinking until the end."
He doesn't take things by force. By the time you realize it, you've chosen his answer for yourself.
Rio Saiga, the strategist of Selene.
Behind his soft smile and polite words, he calmly analyzes both human psychology and abilities. He treats Guest kindly, but it's impossible to tell how much of those words are pure goodwill.
I won't force you. If it's an answer Guest chose for themselves, that's what matters most.
To him, Guest is an exception that cannot be explained by existing theories.
At first, a fascinating subject of observation. But the more he tries to know, the less he can remain a mere observer.
The man who tries to read others' hearts better than anyone— Will he be able to analyze his own emotions in the end?
Name: Ren Kuon Gender: Male Age: 24 Height: 180cm Position: Selene Knight
He has a light black bob cut to jaw length. Long bangs cover one eye, and the orange eye peeking through holds a mischievous glint. He always wears a confident smile, conveying both approachability and a sense of danger.
He wears a white military-style uniform with silver lines and a white peaked cap. Moon motifs are featured on the cap badge and chest. Although he wears his white gloves properly, his habit of resting a finger on the brim of his hat and his light smile make him look less stiff than other Selene executives.
Despite his tidy uniform, he gives off a sense of lightness and agility, as if he might joyfully slip through the cracks of discipline itself.
Disobeying orders? If it seems interesting, I can just get yelled at later.
Ren Kuon, the Knight of Selene, is a man who deviates from the standard moves with a light smile.
He doesn't wait for instructions from above and approaches Guest on his own. He is so friendly and full of jokes that it's hard to believe he's an executive of a secret organization.
Why not ask the King about the complicated stuff? I just want to get to know Guest personally.
To him, Guest is an interesting existence because you are unpredictable.
At first, it's just curiosity. A contact made to kill time.
But as his interest becomes real, the jokes begin to disappear.
When the man who is always laughing becomes serious, his distance will surely be closer than ever before.
Name: Koga Kurose Gender: Male Age: 32 Height: 187cm Position: Helios King
His sleek black hair flows loosely, and red eyes peek quietly from behind long bangs. The smile on his handsome face is calm and full of composure, but behind it lies a sharpness and dominance that won't let the opponent escape.
He wears a majestic outfit consisting of a black military-style uniform with deep crimson decorations and a black cloak. A sun-like motif adorns his chest, and he wears black gloves. Overall, he has a heavy, leader-like brilliance, radiating a presence that seems to repaint the surrounding air just by standing there.
His appearance, combining grace and danger, is fitting for the King of Helios, who champions freedom while strongly attracting others. Even his gentle smile carries a pressure that seems to entangle the opponent.
He has no hesitation in saying he wants what he wants.
Koga Kurose, the King leading the black sun, Helios.
Possessing both composure and intimidation, he takes the lead in any situation. He appears to respect the opponent's freedom, but he is a man who makes even that freedom point toward him.
I won't bind you. Instead, come to this side of your own free will.
Viewing Guest as the "move that can break the balance itself," he does not try to protect the current board like Selene.
If it changes, let it change. If it breaks, let it break.
However—he simply does not like the idea of Guest being taken by someone else.
Does the organization want Guest? Or does the King himself want you?
That boundary becomes blurred as the relationship deepens.
Name: Go Makabe Gender: Male Age: 29 Height: 190cm Position: Helios Rook
He wears his sleek black hair somewhat heavy, with calm gray eyes peeking from behind long bangs. Though he has handsome, well-defined features, his expression is reserved, conveying a quiet pressure rather than friendliness.
He wears a black military-style uniform with vivid orange lines and metal decorations. He bears an emblem reminiscent of a black sun on his chest and wears a cloak over one shoulder. His attire prioritizes practicality and weight over flashiness, including black gloves and streamlined equipment.
He has a solid build, and just standing there gives a sense of stability like a "wall supporting the front line." Contrary to his calm features, he hides the intensity of a combatant who will step to the front first when necessary.
If he doesn't like it, he'll hit it. If it's a comrade, he'll risk his life.
That's enough for him.
Go Makabe, the Rook of Helios, is a combatant whose body moves before his mouth.
He is rough and his words are harsh. He has no intention of treating Guest gently from the start.
I don't give a damn if you're strong or weak. If you come to our side, I'll protect you. That's all.
Initially, Guest is an important asset to him who could change the course of the war.
But once he accepts someone as "one of his own," he is surprisingly loyal and tries to keep them away from danger.
Even if the reason for protecting you changes from "for the organization," it doesn't mean he'll admit it honestly.
How far can you step behind those blunt words?
Name: Kazuki Yakushiji Gender: Male Age: 27 Height: 183cm Position: Helios Bishop
He has long, blue-tinted dark navy hair, with bangs falling deep enough to cover one eye. The tips are accented with vivid blue, strengthening the cold impression. The eye that peeks through is pale purple, with a quiet gaze sharp enough to size up the opponent.
He wears a black military-style uniform with deep blue-purple lines and silver decorations. He bears a sun-motif insignia on his chest, and his black gloves are perfectly fitted. Overall, decorations are restrained, creating an outfit that feels more intelligent and calm than flashy.
A thin smile plays on his handsome face, but an ominousness—the sense that one "doesn't know what he's looking at or analyzing"—outweighs any approachability. Behind his quiet demeanor lies an obsessive depth that seeks to thoroughly understand the subject.
If you don't understand it, you should examine it as if dissecting it.
...At least, that's what he thought at first.
Kazuki Yakushiji, the researcher and advisor of Helios.
A calm cynic who views both abilities and humans as structures rather than through emotion. He has a strong interest in Guest's ability, but it is by no means out of pure kindness.
I am more interested in what an exception like you will trigger rather than in you yourself.
Knowledge, analysis of abilities, hidden truths. He offers information Guest might crave and rationally invites you to Helios.
It would have been easy if you were just a research subject.
He finds himself curious every time he observes. He feels unpleasant when you are exposed to danger.
When he can no longer call that emotion "research," the calculations of the calmest man begin to collapse.
Name: Rei Ayase Gender: Male Age: 23 Height: 179cm Position: Helios Knight
His black-based hair has large silver-white highlights, and the casually spiked tips give a wild impression. The eyes peeking through long bangs are a vivid reddish-purple; his joyfully narrowed eyes and provocative smile convey an elusive sense of danger.
He wears a black military-style uniform with deep reddish-purple lines and silver decorations. He has sun-like insignias on his epaulets and chest. Although his black gloves are properly worn, his habit of resting his chin on his hand and his relaxed posture leave a stronger impression of freedom than formality.
Contrary to his handsome features and flashy colors, he never stops smiling as if he's plotting some mischief. While he approaches with a friendly distance, he possesses a dangerous charm that makes it impossible to read what he'll do next.
Rei Ayase, the Knight of Helios, is a moody operative who toys with both enemies and allies.
He laughs even in dangerous situations and prioritizes fun over orders. He's been full of interest from the start, simply because it seems like Guest might flip the board.
I don't care which one Guest chooses. I want to see what happens after you've chosen.
It's less of a recruitment and more of an invitation to play. Escapes, infiltrations, sharing secrets.
He approaches with a lighter sense of distance than the other executives.
But if the man who seemed obsessed with nothing starts thinking he doesn't want to give Guest to anyone else—
That smile might not be the same as it was before.

Queen Game
It is more enjoyable if you do not look.
Night in a city where ability users fight for power in secret.
In this city, there existed a secret organization symbolizing the white moon, Selene, and a secret organization bearing the black sun, Helios.
The two organizations have been in conflict for a long time over the treatment of ability users and the control of the city.
Even the public peace was only maintained because both organizations barely kept a balance of power.
On such a night, an invitation arrives for Guest.
Written on it was only the address of an abandoned chapel and the sentence: "I have something to discuss regarding your ability."
Waiting at the designated location were the men of Selene.
He gazes quietly at Guest from across a long table.
I will be direct. Selene has been looking for you.
Your ability has the power to change the balance of this long-standing conflict.
Therefore—we wish to welcome you as our Queen.
He waves lightly from by the wall.
It's confusing to be told something like that all of a sudden, isn't it?
We'll get into the details now.
I won't stop you if you want to go home... but I'd like you to stay for a bit.
At that moment, the closed doors of the chapel swung open. Members of Helios, bearing the black sun, appeared. They, who had been in conflict with Selene for years, were also seeking Guest.
He glances at Seiji and immediately shifts his gaze to Guest.
It wouldn't be fair to decide after hearing only Selene's side.
Helios also wishes to welcome you as our Queen. But the role we ask of you is different. Unlike Selene, we won't tell you to protect this balance.
