Mitsuri waited for the tiredness to come.
It didn't.
She helped her mother from morning until afternoon—cleaning, carrying, cooking. When evening arrived, she still felt light on her feet, warmth humming through her limbs like a pleasant echo.
"…That's strange," she murmured.
She wasn't restless.
She wasn't overexcited.
She was just… fine.
When she lay down that night, she tried breathing slowly, the way she always did now.
In—
Out—
Her body responded immediately, relaxing deeper instead of slowing down.
"…Shouldn't I be sleepy?" she whispered.
Instead, she felt like moving.
Quietly, so no one would notice, Mitsuri stood.
She took a step.
Then another.
Her arms followed, tracing gentle curves through the air—not sharp, not strong.
Flexible.
Flowing.
She turned, skirt swaying, breath matching movement without effort.
It felt natural.
That scared her a little.
She stopped, heart steady.
"…Why does it feel like this is normal?" she asked the empty room.
No answer came.
So she tried again the next night.

Akira noticed something else entirely.
His breath stayed.
While cooking.
While walking.
While listening.
He no longer had to start Total Concentration.
It was there when he needed it.
> "Continuous Total Concentration stabilized at low output."
Akira chopped vegetables, hands steady, breath smooth.
The knife never slipped.
At the clinic, he carried water without hurrying, pulse calm even during tense moments.
The doctor watched him quietly.
"You don't rush," the man said one afternoon. "Even when others do."
Akira shrugged. "Rushing makes mistakes."
The doctor nodded. "True."
He paused, then added, "You breathe well."
Akira blinked—then smiled faintly.

Mid-May brought longer days.
Akira trained at dawn as usual, sword movements flowing smoothly into breath and back again.
Not faster.
Not stronger.
Just present.
> "Recommendation: maintain current output for seven more days."
"I will," Akira replied internally.
He trusted the pace now.

Mitsuri's confusion grew.
She ran errands for the neighborhood—and came back smiling.
She carried heavy things—and didn't ache.
One afternoon, she asked Akira quietly, "Do you ever feel like your body doesn't get tired when it should?"
Akira thought carefully.
"…Sometimes," he said. "But I stop before that happens."
She stared at him. "How do you know when to stop?"
He met her gaze. "When breathing stops feeling gentle."
She mulled that over.
That night, she practiced again.
This time, she paid attention—not to movement, but to breath.
When she felt strain, she slowed.
When she felt ease, she flowed.
Her body responded eagerly.
> Why is this so easy? she wondered.
---
Late that week, Mitsuri woke before dawn—without trying.
She lay still, listening.
Her breath was already calm.
Already deep.
"…I didn't even practice," she whispered.
She felt no fear.
Just curiosity.
---
Akira finished his morning training as the sun rose, sweat light, breath steady.
He sheathed the sword and stood quietly.
> "Current growth trajectory stable. No intervention required."
"Good," he murmured.
Elsewhere in Azabu, a girl stretched lazily, full of energy she didn't understand.
Neither of them knew it yet—but they were learning the same lesson from opposite directions.
Some bodies burn out.
Others… never seem to dim.
