---A few weeks later---
Raizen and Hikari faced each other on the mat, real Luminite weapons in hand.
Behind the glass, Mina watched her monitors. At the rail, trainees gathered - including two familiar faces.
Arashi leaned against the barrier, arms crossed, usual smirk in place. Keahi stood beside him, quiet but attentive.
Kori stood at the edge of the mat, chain-knives wrapped loose at her wrists.
"Begin" she winked at Raizen.
Trying to ignore the wink, Raizen stepped in first - pressing in with his blades. Faster than he'd been weeks ago.
Hikari answered every strike. Her staff flowed around his blades like water, redirecting force instead of meeting it head-on.
They'd fought each other enough times now that they knew the patterns. Raizen tried to break hers. She adapted and turned his rhythm against him.
Seven minutes passed. Both breathing hard, sweat-soaked, pushing.
Then Hikari saw it.
A fraction of a second. An opening. Raizen's guard dropping a millimeter too far.
Her staff pulsed once - blue light flaring bright along its length.
She spun.
The movement was instinct. The spear tip traced a perfect arc through the air.
And something followed it.
A thin crescent of blue light separated from the staff and hung in the air - solid, glowing, impossibly sharp - before dissolving like morning mist.
Raizen froze, eyes wide. "Wha—"
"Yeeees, yes. That's enough."
Kori's voice echoed off the walls as she raised her hands.
At the rail, Arashi straightened. Keahi's mouth opened slightly.
The trainees whispered - urgent, confused. "What was that?" "Did she just—" "Eon. That was Eon!"
Kori walked forward slowly, eyes locked on Hikari.
Behind the glass, Mina was on her feet. "That's not possible. Twelve percent can't manifest visible constructs. That requires conscious control, at minimum fifteen percent, and—"
"I know, sweetie" Kori said quietly.
She stopped in front of Hikari. Studied her for a long moment.
Hikari met her gaze, but said nothing. Her expression was calm - too calm for someone who'd just done something quite impossible for her curent skill level.
"You know" Kori whispered. It wasn't a question.
Hikari's silence was answer enough.
Kori's jaw tightened. She glanced at the fading space where the crescent had been, then back at Hikari's face.
"Listen to me." Her voice dropped low, meant only for them. "At the Academy, you don't do that again. Not until you understand what you're pulling from and how to control it properly."
"Fine," Hikari said quietly.
Kori looked at Raizen, then back at her. Something shifted in her expression - concern mixed with something that might have been pride.
"He'd be proud of you both," she said, and everyone knew who she meant. "But he'd also tell you to be careful with power you don't understand."
She stepped back. "Twelve percent multiplier. Clean control. No overload." Her voice returned to normal volume. "You're pretty much ready."
Mina's voice crackled through the speaker. "More than ready. Now get out of my room before you break something expensive."
They left the mat, grabbed towels, wiped sweat and caught their breath.
Arashi and Keahi met them at the door.
"That was nice,l" Arashi said to Raise , genuine this time. He turned to Hikari "Especially the sparkly light show at the end."
Keahi nodded silently. She could use Eon - by drawing it from her blade, she can more or less control a few flames.
"Thanks," Raizen said.
"Don't thank me yet." Arashi's grin returned. "We're entering the exam too."
Raizen blinked. "You are?"
"Did you think you'd have it easy?" Arashi crossed his arms. "Keahi and I have been training for for a long time now. You two are good, but we're better."
"We'll see about that," Hikari said, voice flat but eyes amused.
Keahi smiled. "I just hope we all pass. But if we face each other..." She trailed off, shrugged.
"May the best fighters win," Raizen finished.
"What she meant to say." Arashi scratched his head "was that if you're going to face each other, she is going to step on you" Then he extended his hand. "Good luck. You'll need it."
Raizen shook it. Firm grip, mutual respect. "You too."
Keahi held out her fist to Hikari. This time, Hikari knew what to do.
"See you at the Academy," Keahi said.
"See you there."
They parted ways at the corridor: Arashi and Keahi heading back toward a training bay, Raizen and Hikari toward the exit.
One last time through the hidden door.
One last glance back at the white room that had forged them.
Hikari waved to Mina, knowing she might not see her again, but Mina didn't even see her.
Then they were out in the Underworks, surrounded by familiar noise.
✦ ✦ ✦
Hikari led them up.
Through corridors and stairwells, across narrow bridges, up ladders bolted to pipes. Higher and higher until they reached the Tangle.
The suspension bridges stretched above the Underworks like a web of worn wood and thick cables. From up here, the entire city transformed.
Thousands of lanterns dotted the darkness below - amber, orange, the occasional pale blue - scattered across levels and districts like earthbound stars. Steam rose from vents in slow columns, catching light and turning gold before dissolving into shadow.
The sounds of the Underworks - voices, wheels, hammers, arguments, laughter - blurred into a distant hum, softer and stranger than they'd ever seemed from inside it.
Raizen leaned against the rail, both forearms resting on worn wood. The metal beneath his feet was smooth from decades of boots.
Hikari stood beside him. Close enough their shoulders touched
Neither spoke for a long time.
The air up here was cooler, carrying the smell of metal, old smoke and steam. It moved through Hikari's hair, lifting strands and letting them fall.
Raizen watched a cart move along a distant street, lantern swinging from its side. Watched a child run between buildings. Watched life continue in the undercity that had become home without him noticing when.
"It's strange," he said finally.
Hikari's eyes stayed on the lights. "What is?"
"Leaving." The word felt heavier than it should. "I spent months... almost a year now, just trying to survive down here. Now it feels like I'm abandoning something."
"You're not abandoning it." Her voice was quiet, certain. "You're growing past it. There's a difference, y'know?"
Raizen's fingers curled around the rail. "Obi's staying."
"Obi belongs here. We don't."
"And Takeshi—" His voice almost cracked.
Hikari's nudged him lightly with her shoulder.
"Takeshi gave us the choice to leave," she said softly. "He could have kept us here. Trained us just enough to survive and let that be enough. But he didn't."
She turned to look at him. Her eyes caught distant lantern light. "He wanted us to climb. To be more than survivors hiding in the dark. That's his gift."
Raizen looked down at their hands. When had that become natural? When had her presence stopped feeling like a stranger's and started feeling like the only constant thing in his world?
"I'm... Scared," he admitted.
"Of what?"
"What if we fail?"
"Then we come back and try again." She squeezed his shoulder once. "Or we stay and become Gravers. Or we find another path. But at least we'll have tried. You never know. Maybe the summons is tomorrow! What are you going to say then? You're going to keep being scared"
"Uh - Uhm... I- don't know."
A lantern below went out. Another lit in a different window. The city breathed and shifted and continued without caring who was watching.
"Do you think..." Hikari's voice went softer. "Do you think Takeshi would be proud of us?"
Raizen didn't hesitate. "He already was."
She leaned into him then. Not dramatically. Just a slight shift of weight until her head rested against his shoulder.
They stood like that, watching the Underworks prepare for a new day. The wind carried voices and distant music. Somewhere below, Obi was probably still at his forge, hammering something into shape. Louissa was setting tables. Kori was reviewing her students.
Life continued.
But theirs was about to change.
Suddenly, the silence broke: A deep horn rolled through the Underworks - one long, resonant note that made every pipe tremble and every cable hum. It felt like it came from everywhere at once, reverberating through metal and stone and air.
The summons.
The Lotus Academy's call.
A few lanterns flickered form the vibration. People stopped on the streets below, looking up toward the even though there was nothing to see.
The horn sounded again. Longer this time.
Hikari lifted her head from Raizen's shoulder. Their eyes met.
"Looks like tomorrow came early," Raizen said.
Hikari smiled. "Let's not keep them waiting."
