"Front," Sera spoke softly.

Dorn moved before she finished the word. The shield came up to the ready position in a single motion while Kai moved towards the right side.

"Left." Lina was already moving when the word arrived, which meant she had been reading the space ahead of the call rather than waiting for it. She tracked the right passage with the attention of someone who had already decided where the threat was going to come from.

"The back." Rin settled into the back of the space without adjusting her posture. Her threads were already forming at her fingertips before she reached her position. Silver lines pulling together slowly, the placement starting before the position was fully established.

Rin took the back, threads already forming, eyes on the upper space as before. Kei drifted center, half a step forward of where the back line wanted him. Dorn settled closer to Lina than to Sera. Kai found the open space on the right and moved into it.

Nobody shifted to make room. The gap had just been there.

Then the creatures came. Three of them out of the right passage, bodies low and scaled, moving fast along the floor, the way things do when they were built for exactly that kind of space. They were spread out just enough that one swing wouldn’t catch two of them, but close enough that they were already working together.

[Stone Crawler.]

[Level 16.]

Dorn stepped into the line as the lead Crawler closed. The shield took the impact, and the Crawler was stunned, the half-second window opening exactly where Lina and Kei needed it. Lina was already moving around while Kei was closing from the opposite side.

Kai moved.

Not into the gap made but through the formation itself. Past Dorn’s left shoulder, across the angle Lina was coming from, the distortion already running ahead of his thoughts and putting him at the first Crawler’s best contact point before he’d finished deciding to go there.

[Drop Quality: Optimized.]

Both creatures dropped before the team’s first rotation finished.

The third Crawler saw the loss and changed targets. It read the space the way creatures do. Looking for the nearest open position. It found Lina mid-movement with her angle thrown off by the path Kai had cut through the formation. Dorn was already adjusting, but only by half a step, which was enough.

The Crawler’s claws caught Lina across the side before the armor had fully engaged. It wasn’t deep since her armor deflected most of it. But instead of retreating, Lina stepped forward, not wanting to create a gap in the formation.

Kai stepped in before her hand had finished the motion. One strike, and the last Crawler went down.

[Drop Quality: Optimized.]

The corridor went quiet.

Lina straightened and blinked at the drop, then looked at Kai. Not with anger but with confusion. His strikes had found their targets. His path had also created the opening that let her get hit. Both true at once, and she was deciding what to do with it.

The others wore the same expression. Kai had already reached the problem from the inside. The distortion had found the best solo result and the best solo result cut straight across the formation.

The second wave came before the formation had finished resetting.

[Stone Crawler.]

[Level 16.]

Sera moved first.

Light gathered slowly along her blade’s edge, surpassing the flash from outside the gate, the full thing this time instead of a glimpse.

"Hold formation," she said.

Dorn pushed his shield forward while Lina adjusted her stance with her hand no longer pressed to her side. Kei held center and waited for the exact moment his class worked best. The instant after a creature committed to a direction, it couldn’t change it.

Kai stayed still for a full second. Then he moved into the space the formation was going to create after Dorn’s block and Lina’s arc finished. Not the space that was best now, but the space that would exist in two seconds when the formation’s first movement ended.

The first strike landed inside the team’s rhythm, and then the second followed. The third finished the last Crawler at the moment Kei stepped back, and the gap closed.

[Drop Quality: Optimized.]

No one took damage or was open to an attack this time. The formation held the shape it was supposed to hold.

Sera’s eyes found him for one second after the last Crawler fell. Not the constant watching she’d been doing since they entered. Something more focused, she said nothing and turned back toward the passage ahead.

The next wave had already come

Kai didn’t follow the direction the distortion was already finding for him. He felt the distortion pulling toward the optimal direction, but he forcibly paused it. Letting Dorn go first and have Lina move to her position. Then, Kai moved into the remaining spot rather than the best space.

The formation didn’t break.

He looked at what the distortion had done. Given the limit, it had found the best result inside that constraint. Not the optimal path but still effective.

The monsters fell.

The formation kept moving.

Something shifted behind his eyes for a moment. A brief involuntary brightness, the kind that appeared before a decision rather than after one, there and gone, quick enough that he almost missed it. Lina was facing him from across the corridor, and she looked at his face for one second, then looked away without saying anything.

He filed the tradeoff and kept moving.

The creature types shifted as they went deeper.

[Split Jaw.]

[Level 18.]

Faster than the Crawlers, multi-legged, their attack patterns less straight. Kai used the next three fights to read the team properly. Not the surface-level positioning, but their behavioral tells that only appeared during combat.

Dorn’s shield edge dipped by a fraction before he repositioned. Not much, but enough for Kai to start keeping track of where Dorn was going rather than where he currently was.

Lina would pause for a second when she was approaching. It wasn’t hesitation but her deciding her next course of action. Kei’s grin appeared when an opening showed up earlier than expected. The grin was half a second ahead of the strike.

Useful information.

Rin’s threads came slightly early on creatures moving in straight lines and slightly late on creatures changing direction. She was making up for the latter by placing threads further ahead of her target. He adjusted his signals to give her more lead time on the directional changers.

None of this required him to make up for their gaps. It required him to stop creating situations where they had to make up for him.

Sera said nothing through all of it. She moved, called positions, led from the front, her eyes cycling between the dungeon ahead and the formation behind in a rotation that looked like stillness from the outside. She was tracking multiple things at the same time. Kai was one of them.

Four enemies at the next wave, spread across different angles. The kind of setup that tested whether a formation was actually a formation or just people standing close together.

Kai almost stepped early. The distortion had the best angle before Dorn had set his position, and the pull toward it was immediate and strong.

He stopped for a second before shifting left. The small movement was visible enough to be read as intentional. Lina adjusted her angle without being told to and Kei mirrored the redirect. The formation bent around the new information without losing its shape.

[Distortion Applied.]

[Drop Quality: Optimized.]

[Amplification Complete.]

[Consecutive Chain: Active.]

[Output Adjustment: Increasing.]

The chain had held even when he’d actively suppressed his own movement.

They stopped briefly before the next section.

Kei looked at Kai with the flat directness of someone who’d watched something change and was deciding what the change meant. "You move first, Lina gets hit," he said. No anger in it. Just the fact, stated cleanly.

"I know," Kai said. "That’s on me."

"He adjusted for the second wave," Lina said without turning around. "It’s fine."

"You’re very generous," Kei said with a slight raise of the brow.

"We all make mistakes," Lina said with a shrug. "He fixed it in the same run. That’s more than most people manage."

Kei paused before sighing and nodding his head. He turned his attention back toward the passage ahead since everything had already been said.

Sera was the last one to step forward. She had been watching him since the first wave without saying anything.

"You fight like there’s no one else here," she said.

"Solo runs," Kai said. "This is my first team."

She nodded slowly. "Most people bring that habit into the next dungeon. You dropped it in four engagements."

Kai didn’t answer because he hadn’t expected it to be that fast. The fact that it hadn’t taken longer was, somehow, its own kind of pressure.

Sera looked at him for another second, then turned to the boss’s chamber door. "Keep doing what you just did," she said. "Not moving first. At least until you find a way to make the solo habit work with the formation instead of against it."

She pulled the door open.

Kai stepped through and felt the distortion settle into the new space around him. He wondered what it would feel like once the formation became instinct instead of restriction.

"Formation," Sera said from the front.

Everyone moved into position.

This time, Kai moved with them.
