The soft hum of the spiritual barrier dome shimmered faintly around the courtyard, casting subtle waves of energy through the air. Morning sunlight filtered through its translucent surface, bending and refracting in odd patterns that danced across the grass.
Yuichi crouched near the core node, his fingers running delicately along the etched veins of reishi channels as if inspecting a living organism. Beside him, Niko sat cross-legged, her usual lab coat haphazardly thrown over a dark uniform, sleeves rolled up to her elbows.
"It maintains output stability for two hours now," she said with a grin. "The core's denser than expected, though. It's regulating reiryoku like a viscoelastic membrane. Didn't even intend for that."
Yuichi's eyes lit up. "So it's partially self-healing. That explains the rebound fluctuations when the seal's pressure dips. Did you adjust the mid-layer reishi conductivity or was that a byproduct?"
"Pure accident," Niko admitted proudly. "But now I'm thinking: what if I layer a spiraling pulse circuit on the inner lining? Could stagger barrier reinforcement to adapt in combat conditions."
"Staggered field resonance," Yuichi murmured, his mind already spinning. "That would let you redirect a hit across the barrier's body instead of absorbing it all at one node. You wouldn't even need to anchor it anymore. That would be a definite improvement."
From the sidelines, Mei sipped her tea quietly, her face unreadable. She leaned against the inner wall of the mansion, watching the two as they spoke an entirely different language — full of pulses, seals, flux rates, and conversion delays. She had learned to tune most of it out.
"They're doing it again. This is why everyone avoids the 12th Division.," she muttered into her cup, not unkindly.
Niko, now fully absorbed, opened a small notebook and began sketching a redesigned core system, muttering about using inverted crystal lattices as a waveform governor.
"You could also anchor a kido-linked ward net inside it," Yuichi said. "Use that to double as a long-range sensor grid."
"I was thinking the same thing! But the question is how to get it to resonate with the outer barrier. If implemented would that strengthen, weaken, or leave the barrier strength unchanged?"
Their eyes met in nerdy glee. They droned on for an hour rapidly spewing out ideas that they dissected and reworked constantly.
Eventually, Niko stood, brushing off her knees. "I need to get back to the lab. If I rework the barrier now, I can get a working prototype done by the week's end. I'll bring it over if you're still on lockdown by then. I'll see you two in a week."
"Well, you two seem to have had your fun. I'll walk you to the gate," Mei offered, setting her tea down.
Yuichi waved without rising. "Thanks again, Niko. This is perfect. I can't wait to see the improved version. If you're stuck on anything just pop on down here and we can chat."
"No problem!" she chirped. "Keep feeding me good ideas, and I'll keep making shiny things. Goodbye."
She and Mei walked off through the inner courtyard archway, fading behind the curve of the barrier.
The moment they disappeared, Yuichi's posture shifted. He exhaled quietly, placing his palm over the hilt of his Zanpakutō.
No more distractions.
He moved to the center of the courtyard and sat cross-legged, blade laid horizontally across his leg. With practiced ease, Yuichi let his breath fall into sync with the natural flow of the reishi in the air. Inhale, compress. Exhale, expand. His spiritual energy eventually harmonized with that of his blade, feeding back into his own body in a seamless loop.
The air cooled.
Sound faded.
His body stilled completely.
And his mind… slipped.
The shift was smooth this time.
He opened his eyes in the world of mirrors.
The inner world had changed again.
Clouds still lingered in the skies above — not stormy, but heavy and pregnant with memory. The fault was his own because when distressed or anxious the skies became grey, murky, or even rainy to manifest his worries.
As the view became clear Yuichi was once again met with a breathtaking sight as the realm of mirrors and light, where the ground is a pristine white surface that glows softly. The air is filled with the gentle tinkling of glass, the distant sounds of mirrors breaking, and the occasional melodic wind.
Not far away stood a grand palace made entirely of mirrors, with many levels. The gates ripple like water, giving the illusion that the building is alive.
From within the palace of glass and moonlight, she approached.
A tall, pale woman with waist-length violet hair, tied in a ponytail. A face covered by a mirror-like mask. Wearing a deep red kimono, with large detached sleeves, and a floral pink obi tied into a pale purple bow at her back. She carried an ō katana in an obsidian sheath covered in begonias.
Kagami no Jotei.
The Mirror Empress.
Her presence washed over him like cold, clear water. Regal and silent. She shifted her mask lightly to show her upper face, hiding everything except her soft, knowing smile before returning it to it's place.
She spoke with a calm, regal authority. Her tone reflecting Yuichi's emotional state as she adjusts her teachings accordingly. "You've returned," she said.
"I had to," Yuichi replied, standing slowly. "Things are beginning to change again. Fast. And I don't know if I'm moving in the right direction."
The Empress tilted her head, violet hair glinting in the false light. "You are flirting with with collapse. It seems like you're not satisfied with your current level of strength. As such you seek to change your body faster than it can stabilize."
Yuichi didn't argue. "I know."
Her smile was faint. "And yet, you do not stop."
He looked up at her. "Because I'm running out of time. I'm not sure if I can survive until the things I need to happen occur."
Silence passed between them like a shadow across water.
Then she stepped forward, reaching out.
Her hand touched his chest, over his heart — and for a moment, his entire inner world echoed with the hum of his own reiryoku. She tilted her head again.
"Then show me what you've learned," she said, "as you become more of a warrior you'll come across situations in which you don't know how to proceed. At moments like this fight because that is how a warrior works. Fight occupies the body while your mind frees itself to work out the rest. So show me."
