Asahi remained standing the entire time they waited for the train at the station.
His gaze remained fixed on the tracks ahead, his thumb resting on the hilt, ready to draw at a moment’s notice. He didn't draw it. But his hand was positioned at an angle that would allow him to unsheathe it in an instant.
Koyoi watched his profile. His eyes, which usually looked straight ahead without a hint of doubt, were narrowed and wavering today.
"Does your arm still hurt?"
When Koyoi asked, Asahi gave a short, dry laugh.
"The pain’s not the problem. The problem is knowing why I should cut."
Kuon looked up from his Register. "Reason?"
Asahi continued, his eyes still on the tracks. "In these last few sectors, the line between friend and foe has grown thin. There are those you cut to open a path, and then there are foes you can never take back once you strike."
Koyoi readjusted the pouch in her arms. The Droplet inside was pulsing with a steady rhythm.
"I don't think wavering is a bad thing."
"For someone who fights, it can be a fatal weakness."
His flat tone made the words feel even heavier.
The wind shifted. From beyond the white haze, a single figure began to emerge. It was a silhouette without a face. Only the folds of its robes were unnervingly precise.
"It's a Remnant of an Observer. Don't touch it," Kuon warned immediately.
The shadow stopped before the three of them, swaying as if tilting its head. Then, it looked at Asahi’s sword.
"…Cut me."
The voice was thin and fragile, neither male nor female.
Asahi’s shoulders tensed. "Who are you?"
"A lingering record. I cannot end… while I am still standing."
With those words, the shadow took another step forward. Koyoi instinctively stepped out in front.
"Wait. Let the Droplet touch you."
The shadow froze. As Koyoi opened the pouch, a wave of warmth spread through the space. The shadow’s silhouette softened slightly, and a faint line appeared where its face should have been.
After a brief silence, the shadow whispered.
"…I don't want to be cut. I only want my name back."
Kuon closed his Register and nodded.
"Its coordinates have collapsed; it has lost its sense of self. Asahi, do not strike. Koyoi, provide a placeholder name."
Koyoi nodded and spoke in a low, gentle voice.
"You are a traveler who passed through here. For now, let that be enough."
The shadow’s outline stabilized. It gave a deep, respectful bow before dissolving into the mist.
Asahi let out a long, heavy breath.
"…That was a close one. If I’d cut that thing, I probably would have carried it with me for a long time."
Koyoi offered a small smile.
"Hesitation doesn't just dull the blade. It’s also the time you take to make sure you don’t strike the wrong mark."
The sound of wheels echoed from the distance. The train was coming.
Asahi took his hand off the hilt and then gripped it once more. This time, the grip was deeper, more certain.
"Next time, I’ll move even if I’m wavering. I’ll choose a way that doesn't force me to stop."
The train doors opened, and the three stepped aboard together.
In this sector, Asahi had learned a new way to fight: keep moving, even with doubt.
After the train began to move, Asahi did something rare: he started talking of his own accord.
"In the old days, if I hesitated, I’d just swing first. Thinking made me slow."
Koyoi listened quietly.
"But once you realize there are people like that shadow—people you don’t have to cut—you can’t swing the same way anymore."
Kuon wiped the condensation from the window with his finger.
"When a fighting style changes, the success rate temporarily drops. But in the long run, it improves."
Asahi shrugged. "Don't try to comfort me with statistics."
"It isn't comfort. It's a fact."
Koyoi laughed. The air inside the carriage softened just a little.
The doubt wouldn't disappear. But if they could share it, the weight of it could be divided.
