The sun had climbed high by the time the trio caught their breath. The courtyard still hummed faintly with leftover energy from the Resonance Field. Kaito, Sayaka, and Akihiro sat in a triangle on the scorched stone, silent, drained, but undeniably stronger.
Hishimiya Itsugoyorozu stood before them with her usual effortless grace, sipping tea from a porcelain cup as if she hadn't just nearly burned them alive.
"Lesson one was about precision," she said, her soft pink eyes gleaming. "Lesson two—" she set her cup down gently, "—is about synchronization."
Akihiro groaned. "Didn't we just synchronize?"
"Barely," Hishimiya replied with a teasing smile. "You three connected your energies, yes. But you didn't move as one. Power without unity is just noise."
Sayaka leaned on her staff, still recovering. "What kind of test is this time?"
Hishimiya's smirk widened. "A practical one. The Resonance Field is still active, which means we can use it to simulate a live battle. Against me."
The trio froze.
Kaito blinked. "You're serious?"
"Completely." She stepped forward, the air around her shimmering with a soft golden-pink glow. "If you can land one hit on me before I disarm you all, I'll consider the day's training complete."
Akihiro muttered, "We're dead."
Sayaka smiled weakly. "Let's just… try our best?"
Kaito stood up, drawing his blade. "No — we'll do our best."
Hishimiya clapped once, and the courtyard shifted instantly. The sigils beneath their feet reactivated, forming a circular arena enclosed by glowing barriers. The atmosphere tightened — even the wind stilled.
"Begin."
Before they could react, Hishimiya vanished.
Kaito's instincts flared — a flicker of pink light appeared behind him. He spun, blocking just in time as her fingertip grazed his blade, sending a pulse through his body that numbed his arm.
"So slow," she whispered playfully. "You think Celestial energy alone makes you untouchable?"
He gritted his teeth, summoning Hikari Ami Fusion. Light and darkness spiraled around him, forming a balanced aura that flared outward. Sayaka followed, her Spirit Core glowing brighter in response, forming a defensive barrier around the trio.
Akihiro closed his eyes, activating Spatial Awareness, his perception stretching across the field. "She's moving through the reflection of her own Eien Ryoku," he muttered. "Predict the shimmer — that's where she'll strike next!"
Kaito nodded. "Sayaka, cover left! Akihiro, trace her movement!"
They moved as one — Sayaka's barrier pulsing with ethereal blue light as Akihiro blinked across the field, planting distortion seals midair.
The next shimmer appeared — Kaito slashed, his blade meeting hers in a burst of radiant energy.
"Better," she said softly, her eyes gleaming. "You're beginning to listen to each other."
But before he could react, she twisted gracefully, her fingertip tapping the back of his sword — and his energy flared out of control, dispersing into wild sparks.
Sayaka's eyes widened. "Kaito!"
"I'm fine!" he shouted, quickly grounding his energy through his feet. The ground beneath him cracked, his aura stabilizing once more.
Hishimiya floated backward, her hair swaying like liquid silver. "Lesson two — Precision in motion. Energy balance depends not just on control, but on rhythm. You must feel the flow of your allies."
She spread her hands — countless pink threads formed around her, each glowing with faint hearts and stars. "Let's see how long you last against Pure Fate Resonance."
The threads shot toward them like whips of light. Sayaka reinforced her barrier, but each strike distorted the surface, shimmering like ripples on water. Akihiro blinked between dimensions, redirecting the threads through spatial loops.
"Now, Kaito!" he shouted.
Kaito's blade ignited, Celestial light bursting forth. He dashed through the openings Akihiro created, his movements synchronized with Sayaka's emotional pulse.
For a brief moment, their energies aligned perfectly — a triad of light, emotion, and perception.
He swung. The blade's arc of silver and black light streaked forward, grazing Hishimiya's shoulder.
A soft ping echoed through the air.
And then — silence.
They froze. The pink glow around the courtyard faded, the sigils dimming. Hishimiya touched her shoulder lightly where his blade had grazed her robe, then smiled.
"Well done," she said softly. "That was one hit. A clumsy, barely-coordinated, but genuine hit."
Sayaka dropped to her knees, panting. "You're saying that like we didn't almost die."
"Almost dying," Hishimiya said with a serene grin, "is part of the process."
Akihiro flopped backward, staring at the sky. "You're evil."
"Correct," she replied without hesitation.
Kaito lowered his blade, panting, a small grin tugging at his lips. "That was… insane."
"And yet you succeeded," Hishimiya said. "Because for a moment, you trusted each other's rhythm. That is Resonance — the heart of every Tsukimori team."
Her expression softened, and she knelt before them. "Remember this feeling. When you're out there facing real Kuzuremono, your hearts will be your only connection. Fail to listen to each other's energy, and you'll fall apart."
Sayaka nodded weakly. "We'll remember."
"Good." Hishimiya stood, stretching elegantly. "That concludes today's training. Rest. Tomorrow, we begin phase three — Resonance Combat. You'll fight together against a simulated Kuzuremono."
Akihiro groaned. "I was afraid you'd say that."
She winked. "Oh, come now. You're enjoying this."
Kaito smirked faintly, resting his sword on his shoulder. "Maybe… a little."
As Hishimiya walked away, the trio exchanged glances. They were bruised, exhausted, and half-broken — but for the first time since joining the Tsukimori Association, they felt united.
Sayaka smiled softly. "We actually hit her."
Akihiro chuckled. "Barely."
Kaito looked toward the fading sigils on the ground, his expression thoughtful. "Still… it means we're improving."
The wind carried their laughter across the courtyard — three young Tsukimori, unaware that beyond the Association walls, something dark had begun to stir.
Far beyond the city, in the shadows of an ancient shrine, a faint crack appeared on a sealed stone tablet — the mark of Kage no Michi.
And as the light dimmed, the air whispered of the past returning.
The next lesson would not be training.
It would be survival.
