Erza closed her eyes—and felt space bend.
Not numbers.
Not windows.
Space.
A pressure unfolded behind her sternum, deep and vast, like opening a door into a hall that had always been there, waiting for her to notice it.
Her magic didn't show her a system.
It gave her a place.

The Pocket Dimension
When Erza reached inward, she didn't see icons or lists.
She felt distance.
A crimson-lit void stretched before her senses—endless shelves of suspended space, each anchor point ready to hold steel, leather, mana.
Empty.
For now.
She raised her hand instinctively.
Re-Equip.
The Knight armor formed around her in an instant—plates locking, mana settling—not summoned from nowhere, but pulled through space that belonged to her.
The sensation was unmistakable.
This wasn't storage.
This was ownership.

"Kaito," she murmured, eyes opening. "I can feel it."
He stood nearby, watching intently—not the armor, but the distortion around her.
Great Sage spoke quietly to him.
> Assessment: Spatial magic manifestation confirmed. Type — Personal Pocket Dimension. Capacity scalable. No external system detected.
Good.

Instant Re-Equip
Erza moved.
She sprinted—and mid-step, reached inward.
The armor shifted.
Not removed.
Replaced.
Lighter greaves for speed. Reinforced chestplate for balance.
At the same time, the sword in her hand vanished—another blade snapping into place in the same heartbeat.
No pause.
No loss of momentum.
Her body didn't hesitate.
Space obeyed.
Erza laughed, exhilarated.
"I didn't pull them out one by one," she realized. "They just… came."
Kaito nodded. "You're not retrieving items. You're repositioning space."
She grinned fiercely.

Filling the Arsenal
They trained slowly after that.
Each weapon Kaito forged.
Each armor piece stabilized.
Erza drew them inward—not storing them like objects, but anchoring them to fixed points inside her dimension.
The space responded, expanding slightly with each successful bond.
Not infinite.
But growing.
By afternoon, her pocket dimension held several weapons and armor variants—each perfectly accessible, each waiting in silence.
Erza stood still, eyes closed, mapping distance and placement.
"I know where everything is," she said softly. "I don't have to look."
"That's because it's part of you now," Kaito replied.

Limits
When fatigue crept in, Erza felt it immediately.
Not pain.
Resistance.
Space pushed back.
She stopped at once.
Kaito was already beside her.
"Your magic is fine," he said. "Your body's the limiter."
She nodded, breathing hard.
"So if I force it—"
"You risk spatial desync," he finished. "We won't do that."
She smirked faintly. "Not yet."

The Knight's Domain
As evening fell, Erza stood alone in the clearing.
She reached inward.
Steel answered.
Armor formed.
The Knight stood complete.
Erza clenched her fist, feeling her pocket dimension settle—quiet, vast, hers.
Not a tool.
Not a system.
A domain.
And she would fill it—piece by piece—with her own strength.
