[Scene: Zenrai Institute — Class A Training Grounds, Morning]

The sun cast clean golden rays across the open training grounds. Mana circuits buzzed in the air, amplifying pressure for live sparring sessions.

Instructor Roen’s voice cut through the crisp morning air.

“Two rounds. Partner duels. No fatal blows. Impress me, or leave.”

Class A students stood in rows, paired up. Kaien adjusted his gloves, eyes narrowed. His partner? None other than Aizen.

Again.

“Seriously?” Kaien muttered. “Are they trying to make us kill each other?”

Aizen stood silently, stretching his shoulders. “Not today. I’m still sore from last week.”

Kaien scoffed. “You always look half-asleep. One of these days, I’m gonna break that calm expression of yours.”

Aizen looked over, a faint smirk curling on his lips. “Try it.”

[Scene: Sparring Begins — Aizen vs Kaien]

Roen raised his hand. “Begin.”

BOOM!

Kaien vanished in a burst of lightning-imbued mana. Aizen ducked under his opening strike, countering with a sweeping blade. Kaien spun mid-air, deflecting the attack with a reverse kick that barely missed Aizen’s face.

“You hesitated,” Kaien said.

“I blinked.”

“You flinched.”

“You overthink.”

Their blades clashed again. This time, the sparks lingered.

The crowd watched in silence.

Kaien’s face was focused, serious—his movement sharp and without waste. Everything about him screamed perfectionist. He hated mistakes. He hated slowing down.

Aizen? Still calm. Still watching. Calculating. His power wasn’t overwhelming—it was controlled.

Their styles didn’t clash. They competed.

And when the final strike came, they both held back just enough.

Instructor Roen clapped once. “Match ends. Good restraint. Barely.”

Kaien stepped back, wiping sweat from his brow. “You’re lucky I’m still warming up.”

Aizen exhaled. “Sure. Let’s go with that.”

[Scene: Dining Hall, Noon]

Aizen sat across from Sumiko at the long cafeteria table, while Kaien leaned on a chair nearby, brooding over his untouched tray.

“You didn’t eat again,” Sumiko said.

Kaien grunted. “Not hungry.”

Aizen sipped his tea. “Still mad?”

Kaien didn’t answer.

“Let me guess,” Aizen continued, “You thought you’d beat me clean this time.”

Kaien’s eyes narrowed. “One of us is being held back by dead bloodlines. It’s not me.”

Sumiko’s gaze snapped up. “Kaien.”

Kaien sighed. “I’m not wrong.”

Aizen stood slowly. “You’re not. You’re just loud about it.”

For a moment, the silence between them was dense.

Then Kaien muttered, “Don’t go easy on me next time.”

Aizen nodded. “Wouldn’t dream of it.”

[Scene: Zenrai Library — Evening]

The large hall was quiet. Scrolls floated on gentle mana currents as students studied for their weekly theory test.

Sumiko sat beside Aizen at a long table. Books were open between them—mana equations, combat diagrams, elemental channeling formulas.

Sumiko pointed to a formula. “You missed the fourth variable here.”

Aizen frowned. “That’s because it’s useless in practice.”

She gave him a side glance. “You think everything’s useless until it breaks your ribs.”

He chuckled quietly. “And even then, I call it a learning experience.”

They worked in silence for a while. Quiet. Comfortable.

Sumiko finally spoke. “You and Kaien…”

Aizen looked up. “What about us?”

“You’re opposites. But it’s like neither of you want to win. You’re both chasing something else.”

Aizen was silent for a moment. Then: “I’m not chasing. I’m building.”

She looked at him a long time. “You’re hard to read.”

“And you’re easy to underestimate.”

A tiny smile cracked on her face. “Tch. You’re still weird.”

Aizen grinned. “I get that a lot.”

[Scene: Tower Rooftop — Late Night, Unknown Masked Figure]

The silver-masked figure stood at the edge of the northern watchtower. Beneath him, Zenrai’s lights shimmered.

He watched. Unmoving.

Another presence appeared behind him—a silhouette with violet eyes.

No words were spoken.

But far below, the bonds of a future team—the rivalries, friendships, feelings—were being forged.

Fault lines. Deep and silent.

Waiting.
