The gym smelled of fresh floor wax and chalk dust, and somewhere in the back of Karasuno’s court, Ukai was assembling a mock-wall out of players who’d never blocked together before.
Three bodies at the net.
Three sets of arms rising in imperfect unison.
The gap between the wing and the middle was wrong by maybe six inches — enough for a spike to slip through, enough for the Iron Wall to be misrepresented — but the approximation was close enough for a drill.
Ukai had scavenged three second-stringers for the wall and given them one instruction: hold the shape, don’t think, react.
It wasn’t the Iron Wall.
It wasn’t close.
But three bodies moving in the same general direction was enough to test a theory against, and a theory was what Tsukishima had instead of the real thing.
“The right-side rotation closes late,” Tsukishima said.
He was standing at the net with his arms folded, watching the mock-wall with the same flat assessment he’d aimed at the real one.
“Third-of-a-second gap.
The wing slides.
The middle compensates.
If the set is fast enough, the gap stays open.” Kageyama was already behind the ten-foot line, a ball in his hands, his eyes doing the particular narrow thing they did when he was calculating angles.
“Fast enough means what.” “Fast enough means you don’t give the middle time to adjust.
The gap is between Aone’s left arm and the wing’s right.
If the ball is already past the tape before the wing closes, the gap is a point.” “And the quick.” “The quick doesn’t work against the wall.
Aone reads the quick.
He read it three times in the scrimmage.
You’ll need a different weapon.” Kageyama’s jaw tightened.
The setter didn’t like being told his weapon had a counter.
But the data was the data, and Kageyama respected data more than he respected pride.
“What weapon.” “Speed to the outside.
Not the quick.
A clean arc.
The arc gives Asahi time to approach.
The approach gives Asahi the angle.
The angle beats the wall on the short seam.” “You’re sure.” “I’m sure the wall closes slow on the right.
I’m not sure about anything else.” Kageyama processed that for a moment.
Then he turned to Asahi, who was stretching near the sideline with the expression of someone who’d just been volunteered for something difficult.
“Asahi.
Outside.
Short seam.” “Right.
Short seam.” Asahi’s voice was steady, but the hands that picked up the ball weren’t.
The glass-heart was still there — always there, but under the steadiness, something else.
A willingness.
A thing that hadn’t been there before the scrimmage loss.
Yamaguchi watched from the sideline, a towel around his neck, saying nothing because there was nothing yet worth saying.
Nishinoya bounced on his toes near the back row, itching for a ball that wasn’t coming his way in this particular drill.
They ran the drill.
Tsukishima didn’t need to watch the mirror image to know roughly what it looked like.
Aone’s gym, three towns over, running the same three-man drill it had run for three years: arms up at the clean angle, no seam, no daylight, wing blockers closing around him like a door finding its hinge.
Futakuchi would be running his mouth on the sideline out of pure habit, and somewhere in that noise there’d be a line about the tall kid with the glasses who’d called their rotation before they’d run it.
I don’t like being seen, or close enough to it.
He’d never confirm the guess.
He didn’t need to.
Reading a wall long enough meant the wall eventually noticed it was being read.
The drill ran.
Kageyama set to the outside.
Asahi approached.
The mock-wall closed, imperfect, six inches off, but close enough, and Asahi’s spike found the seam.
Not clean.
Not a spike that silenced a gym.
But it found the seam.
Tsukishima logged the result.
“Faster.
The seam closes if the approach is slow.
Asahi’s approach is three steps.
The third step needs to land before the wing commits.” “How do you know that,” Asahi said.
“Because the wing commits on the hitter’s second step.
If the hitter’s third step lands before the wing’s arms go up, the hitter has the angle.
If the hitter’s third step lands after, the block wins.” Asahi stared at him.
“You watched the wing’s timing.” “I watched everything.” “That’s.
extremely specific.” “That’s the point.” Asahi exhaled, something between a laugh and a wince.
“You’re not human.” “I’m a blocker.
There’s a difference.” They ran the drill again.
Faster.
Asahi’s third step landed a half-beat earlier.
The mock-wall closed around empty air and the spike hit the floor on the far side of the court.
Not perfect.
Not the Iron Wall.
But closer, and closer was a direction, not a destination.
Small on a stat sheet.
Enormous on game day.
Ukai watched from the sideline with his arms crossed.
His clipboard was making that particular note again: the one that meant he’d seen something useful and intended to use it.
“That’s the counter you’re building.” “It’s not a counter yet.
It’s a theory.” “Your theories keep being right.” “Most theories are right until they’re tested.
The testing is the part that matters.” Tsukishima adjusted his glasses.
“Date Tech is going to be in the bracket.
We’re going to face them again.
If the counter works in drills, it works in a match.
If it doesn’t, we need a different counter.” “And you’re going to figure out which.” “Asahi’s going to figure out which.
I’m just providing the intel.” Sugawara appeared beside him during the water break.
The vice-captain was holding a clipboard of his own, notes, diagrams, the beginnings of a serve-rotation built on the same intel Tsukishima was providing.
“The right-side seam.
If you can call it during a match, I can build a serve around it.” “The right-side seam is there for maybe a third of a second.
If the serve is slow, the wall closes before the spiker reaches the ball.” “Then the serve needs to be fast.” “The serve needs to be Yamaguchi’s.” Tsukishima didn’t look at Yamaguchi, who was on the far court practicing the float that had been dying in the net all week.
“His float.
The movement off the contact.
If the serve moves, the wall has to read the serve before it can read the spike.
If the wall is reading the serve, the gap on the right stays open for an extra beat.” Suga’s expression shifted.
Not surprise.
Assessment.
“You’ve been thinking about this.” “I’ve been thinking about the wall.
The wall is a problem.
The wall requires a solution.
The wall is also three people, and three people can be divided if you hit the right seam at the right speed.” He walked back to the net before Suga could ask the next question.
The question was obvious.
The answer was too.
He’d been thinking about the wall because the wall was a problem, and every problem had a solution if you were willing to invest the attention to find it.
He was invested.
He’d been invested since the bus.
He was just pretending he hadn’t noticed.
