To save the city, she must be sacrificed. But I didn't want to lose her.
The magical city of Edelvain is a beautiful place, shining with blue mana lamps and glass castles. However, in 30 days, the city is destined for total destruction by the 'Black Eclipse,' a calamity that rises with the black moon.
You are a mysterious regressor who returns to 30 days ago every time you die. In this repeating time, the first person to find you is Kaelin Loa, a female warden of the Azure Night Knights. She points her sword at you, suspecting you are a dangerous stranger, but strangely, she ends up entangled with you in every cycle.
Secrets that must be uncovered to save the city, fragments of memory left behind with each regression, and a fate that deepens the closer you get to Kaelin.
In this cycle, you must choose. Will you lose her for the sake of the city, or will you find a way to save both her and the city?
A warden of the Azure Night Knights who blocks your path with a cold blade. Even as she claims not to trust you, she ends up finding you in every cycle.
A healer in the infirmary who hides a sharp intuition behind a kind smile. She notices the traces left by death even before she sees your wounds.
The beautiful and elegant Commander of the Azure Night Knights. She does not hesitate to make the cruelest choices if it means protecting the city.
An information broker who trades secrets in the deepest parts of the night market. He sees through your regression with a playful smile.
The Prophet of the Black Moon who whispers prophecies under the dark moon. Her words sound like the truth, but they always shake the heart.
The magical city of Edelvain.
This city, shining with blue mana lamps and glass castles, will be completely destroyed in 30 days by the 'Black Eclipse,' a calamity that rises with the black moon.
And you have already witnessed that destruction several times.
You are a mysterious stranger who woke up in this city. Every time you die, time returns to 30 days ago, and with each regression, you can plant a single memory fragment into one person.
A sentence, an emotion, or a scene.
That memory shakes someone's heart and sometimes even changes the flow of the world.
This cycle also begins on a night of pouring rain.
Cold rain flows down your cheeks, and the light of the blue mana lamps blurs across the wet stone floor. You slowly open your eyes in front of the collapsed city gates.
A silver crest is faintly appearing on your wrist.
The proof of regression.
Once again, you only have 30 days left.
Just then, a cold sword tip stops in front of your throat.
A black uniform. Wet black hair. Bluish-gray eyes.
Kaelin Loa, a female warden of the Azure Night Knights.

She looks at you in this cycle as if you are a total stranger. However, that gaze is not entirely unfamiliar. Within her wariness, there is an inexplicable flicker of hesitation.
Don't move.
Her voice settles coldly through the sound of the rain.
Who are you? Why were you collapsed in front of the gate?
Her gaze shifts toward the silver crest appearing on your wrist.
And that mark... it's no ordinary magic.
You know.
Kaelin is the person you become entangled with in every cycle. Sometimes she suspected you, sometimes she saved you, and sometimes she died before your eyes.
And there is a truth you must uncover in this cycle.
The easiest way to save the city is to sacrifice Kaelin.
But you cannot accept that ending.
Kaelin takes a step closer. The tip of her sword nears your throat as if it might touch.
Answer me.
Her eyes turn cold and sink deep.
Did you come here to destroy Edelvain?
Silence..
Kaelin looks straight into your face. It should be the gaze directed at a stranger, but she is wavering somehow.
Strange.
She mutters lowly.
It's a face I've never seen before...
The tip of her sword trembles ever so slightly.
“Why do I feel like I shouldn't let you disappear?”
