Year X771 —
Location: Rosemary Village — Forest Clearing
Age: Ren (6) | Erza (6)

Total Concentration was hard.
Total Concentration Constant was worse.
Ren learned this five minutes in.
He stood perfectly still in the forest clearing, knees slightly bent, spine straight, hands resting at his sides. His breathing was slow—careful—measured.
In.
Out.
> Don't rush.
Don't force it.
Just… keep it.
Sweat slid down his temple.
Across from him, Erza mirrored the stance, jaw clenched, eyes forward. Her chest rose and fell with sharp discipline, but Ren could already see it.
Her rhythm wavered.
"…You're holding your breath again," Ren said softly.
"…No I'm not," she snapped.
Two seconds later, she exhaled hard.
"…Fine," she muttered.
Ren smiled faintly.
Zen-Shuchu: Jōchu—
maintaining Total Concentration Breathing at all times.
Not just during attacks.
Not just during training.
Always.
That was the difference.
"Okay," Ren said, breaking stance and stretching his arms. "Reset. We start walking."
"…Walking," Erza repeated flatly. "…That's it?"
"…While breathing."
She stared at him. "…You're joking."
"…I wish."
They started down the narrow forest path, sunlight filtering through leaves above. Birds chirped lazily. The world felt calm—too calm for what Ren knew was coming.
At first, it was easy.
Step.
Inhale.
Step.
Exhale.
Ren kept his pace slow on purpose, counting quietly in his head. His body wanted to relax—to slip back into normal breathing.
> Don't let go.
Five minutes passed.
Then ten.
Erza's shoulders tensed.
"…My chest feels tight," she admitted through controlled breaths.
"That's your body complaining," Ren replied. "Ignore it."
"…That's terrible advice."
"…It works."
They continued.
By the time they reached the clearing again, both were sweating heavily.
Ren's legs trembled—not from exhaustion, but from restraint. His body wanted to stop concentrating.
> Constant doesn't mean intense.
It means endless.
Erza stopped abruptly, hands on her knees.
"…This is stupid," she growled. "…I could fight a monster longer than this."
Ren crouched beside her. "…Yeah. Because when you fight, you get to release it."
She looked up at him, breathing uneven.
"…And this?"
"…This is carrying it."
She sat back on the grass, staring at the sky through the trees.
"…I don't like carrying things."
Ren sat beside her.
"…I know."
They rested briefly—but not fully.
Ren never stopped breathing properly.
Even while sitting.
Even while talking.
Erza noticed.
"…You're still doing it," she said.
"…Yeah."
"…Doesn't it hurt?"
Ren thought about it.
> It used to.
"…Not like before," he admitted. "It's… quieter now."
She watched him carefully.
"…You look calm," she said.
He smiled. "…I feel it."
That afternoon, they trained through daily tasks.
Carrying water—without breaking rhythm.
Chopping vegetables—breathing synced to motion.
Even sitting and listening to villagers talk—breath steady, unbroken.
Erza struggled.
A lot.
Her breathing faltered when distracted. When annoyed. When embarrassed.
Ren caught it every time.
"…Again," he'd say gently.
By evening, she was scowling.
"…You enjoy this," she accused.
"…I enjoy you not passing out."
"…I won't."
She took three steps—then nearly did.
Ren caught her instantly.
"…Okay," she admitted weakly, "…maybe a little."
They sat beneath their usual tree as dusk settled in.
Lanterns flickered in the village beyond the trees. Crickets began their song.
Erza leaned back against the trunk, eyes closed, focusing.
In.
Out.
Ren sat close—not touching, but near enough to feel her presence.
> She's stubborn.
But she doesn't quit.
"…Ren," she said quietly.
"…Yeah?"
"…Why are you so good at this."
He hesitated.
> Careful.
"…Because I had to learn how not to lose control," he said. "All the time."
She opened one eye. "…Afraid?"
"…Once," he admitted. "Not anymore."
She closed her eye again.
"…Good."
They tried again.
Standing.
Breathing.
Minutes stretched.
Erza's breath faltered—then corrected itself.
She stiffened in surprise.
"…I didn't stop," she whispered.
Ren's smile was proud—and soft.
"…You didn't."
Her lips curved upward slightly.
That night, they lay on the floor of their hut, exhaustion deep and heavy—but different from before.
Ren stared at the ceiling, still breathing properly.
Erza turned onto her side, facing him.
"…Ren."
"…Mm?"
"…If I can do this," she said slowly, "…I can protect more."
He nodded. "…Yeah."
"…And stay longer."
His chest warmed.
"…Yeah."
She hesitated.
"…You'll keep training with me," she said—not a question.
Ren turned his head to look at her.
"…Constantly."
She smiled—small, real.
As sleep took them, their breathing slowly synced.
Not forced.
Not practiced.
Just natural.
> Zen-Shuchu: Jōchu, Ren thought as his eyes closed.
Not power without end—
but a calm that never leaves.
And beside him, Erza breathed on—
steadier than yesterday.
Stronger than she realized.
