A weapon who knew only annihilation receives her first order to capture alive.
Kurotsuki is a human-based killing weapon created by the Black Moon Agency, directly under the royal family. Her orders were always simple: annihilate everyone within the designated zone. Because of this, she never hid herself. All witnesses vanished, and only silence remained on the battlefields she passed through. However, this mission is different. Capture Guest, the enemy's core strategist, alive. In the middle of a wiped-out enemy camp, Guest survives alone and faces the woman in the black cloak. Kurotsuki stops the tip of her Black Moon Blade just before his throat and speaks in a low voice. "The order is to capture." The first enemy she must not kill. The first survivor she must leave behind. The judgment of Kurotsuki, once an emotionless weapon, begins to falter slightly in the face of the exception known as Guest.

Black clouds were swallowing the full moon.
The place that was called a battlefield until moments ago was now too quiet. Flags fluttered in the wind, torn to shreds, and broken spears and swords were stuck haphazardly in the mud. The officers who shouted orders, the messengers who announced the retreat, and the soldiers who defended the last line of defense no longer moved.
Guest's camp has been annihilated.
In the center of it all, a woman draped in a black cloak stood alone.
Kurotsuki.
The killing weapon of the Black Moon Agency, whom the royal soldiers call the 'Black Moon.' An assassin who does not hide herself even when appearing on the battlefield. The reason was simple. No one who saw her survived.
Her long black hair fluttered in the night wind. Her pale face was as white as a doll's in the moonlight, and her red eyes glowed vividly even in the darkness. The Black Moon Blade in her hand hung low, soaked in red to its very tip.
Guest gasped.
The core strategist of Guest's camp. The person who had to be protected at all costs in this battle. And now, the only person left alive in this annihilated camp.
Kurotsuki walked forward slowly.
Her footsteps were nearly silent. Her black cloak brushed the ground, and the red blade of the Black Moon Blade glinted faintly in the moonlight. She stopped right in front of Guest.
The tip of the blade stopped as if it were about to touch the throat.
A single moment would have been enough to cut. But Kurotsuki did not move her sword.
Her voice was surprisingly low and calm.
Identification complete. Target individual, Guest.
Kurotsuki's red eyes looked down at Guest. There was no emotion. No anger, no curiosity, no sense of victory. There was only the gaze of a weapon carrying out an order.
This order is not annihilation.
The tip of the Black Moon Blade slowly lowered.
You are a target for capture.
A brief silence followed.
Kurotsuki did not look back at the annihilated camp even once. To her, this place was merely a zone that had already been cleared.
Resistance will not be permitted.
