The lines were misaligned. Just one, at the very edge of the sea chart—but that was enough to turn the path into a lie.
Koyoi rested the ledger on his knees, tracing the line with a damp finger. The ink bled, blurring the path into something even more ambiguous.
"…It moved again."
Kuon spoke curtly. The azure glow of his prosthetic eye swept across the paper.
"It’s not the terrain. The line itself is swaying. The Observer is redrawing the boundary."
Asahi turned his gaze toward the pier at the edge of the harbor. He could smell the salt in the air, yet the sound of the waves arrived a heartbeat late.
"A delay?" Koyoi murmured.
Kuon nodded. "A seam in the laws of nature. The thread of time is snagged right there. When the line shifts, your stride shifts with it."
Koyoi placed his hand over the drawstring pouch at his waist. Inside, the Shizuku gave a faint, rhythmic pulse.
"Can we… fix it with the Shizuku?"
"We don’t fix it. We follow it," Kuon said sharply. "If the line moves, we move with it. But we keep the displacement within ourselves. Once everything is aligned, the path will be set."
Asahi let out a short laugh. "Sounds convoluted."
"The more convoluted it is, the more 'alive' it is," Kuon retorted.
Koyoi walked to the edge of the pier and peered down at the water. The harbor lights were reflected upside down on the surface. They were swaying, yet the rhythm was strangely constant—as if someone were forcing the "sway" into a predetermined mold.
Koyoi dropped a small stone. Ripples spread outward, but halfway through, the circle of the wave distorted, bending unnaturally.
"…It’s shifting."
Kuon nodded. "The stitching of the boundary is showing in the water. That’s why the sea chart goes mad first."
Asahi fixed his eyes on the far end of the pier. "Then we just have to step right onto the seam."
"…Spoken like a true swordsman," Kuon muttered, though he didn't disagree.
Koyoi folded the sea chart and held it close to his chest. The shifting lines were frightening. But being able to feel that shift was proof that his own outline—his own self—still remained.
"…Let’s go," Koyoi said.
At the end of the pier, a sudden gust of wind caught the corner of the chart, flipping it over. For a fleeting second, the lines seemed to snap back to their original positions. Someone was waiting. At the end of the line.
Koyoi slipped his finger into a fold of the chart. He felt as though another line was lurking within the thickness of the paper. His fingertip caught on something. Not ink, but a shallow groove, like a mark carved with a needle.
"…This line isn't written."
Kuon leaned in to look. "A draft. The architect hid the only lines they wanted to preserve until the very end."
Asahi grinned. "Then that’s the real one."
Kuon gave a small, dry smile. "'Real' is a dangerous word. But… it’s worth following."
Holding the chart tight, Koyoi stepped away from the pier. The misalignment didn't vanish. But knowing there was a hidden groove beneath the shift changed the very ground beneath his feet.
At the end of the pier, a ripple in the water distorted once more. This time, it moved in perfect sync with the footsteps of the three.
