Eira Lumi and Neo returned to the outskirts during the academy break, and the change in air was something they both felt the moment the carriage left the main road. The heavy stone of the city gave way to open fields, wooden fences, and the scent of grass and river water. Neo leaned out slightly, smiling as the wind brushed her hair back.
"It feels like I can breathe again," she said quietly. Eira nodded.
"That's what this place does," he replied.
It was home, simple and quiet, and after months of being inside walls and rules, it felt like stepping into a softer world.
Lumi welcomed them first, her silver hair tied back, her hands already warm from cooking. She pulled Neo into a gentle hug without hesitation.
"You look healthy," she said with relief.
"Both of you do." Peris followed behind her, offering Eira a quiet nod and a firm hand on his shoulder.
"You're standing straighter," he said.
Your training is working." Eira smiled faintly. He felt lighter here, like the weight he carried in the city could finally loosen its grip.
The next day, Eira went to meet the adventurers who had once taken him under their wing. Kara was sharpening her blade when she saw him, her ears twitching in recognition before her eyes lifted.
"You're taller," she said flatly. Lior laughed from behind her.
"That's what happens when kids grow, Kara." Ethan watched Eira closely, his expression more serious than the others.
"How's the academy?" he asked. Eira hesitated.
"Busy," he answered honestly.
"Different from adventuring." Kara snorted.
"Everything is easier when someone else handles the danger."
Ethan's gaze hardened slightly.
"Listen," he said quietly, lowering his voice.
"Things aren't normal lately." Eira frowned.
"What do you mean?" Lior leaned closer.
"Monster numbers are up. And not in a good way." Kara crossed her arms.
"They're twisted. Aggressive. Wrong." Ethan nodded.
"And the mana near the academy… it feels polluted. Like something is stirring underground." A chill ran through Eira.
"So you think something is coming?" Ethan met his eyes.
"We think something already started. Be careful, Eira." Kara pointed at him.
"And don't try to carry everything alone again."
Eira bowed his head slightly. "I'll be careful."
Later that afternoon, Eira took Neo deep into the forest.
"I want to show you something," he said as he guided her off the usual path. Neo laughed softly.
"You always say that right before I get scratched by thorns." When they reached the clearing, she stopped. The river curved gently through soft moss, and glowing insects hovered near the water's surface.
"It's beautiful," she whispered. Eira watched her more than the scenery.
"I found it while adventuring," he said. "It felt like a place that shouldn't be alone." Neo turned to him.
"So you brought me," she said, and sat beside him. They stayed there quietly, her head resting against his shoulder, the world distant and unimportant.
That night, family and friends gathered for a small feast. Lanterns glowed warm against the dark, and laughter filled the yard. Neo sat beside Eira, holding a cup of warm drink.
"I don't want to go back yet," she admitted.
"Me neither," he said. She looked at him and smiled.
"Then promise me we'll come back. No matter how far we go." Eira nodded. "I promise."
When they returned to the academy, everything felt louder again. Stone replaced grass. Rules replaced silence. Yet something inside Eira felt steadier.
A few days later, rumors spread about a noble student named Jack, who used gravity magic and had taken an interest in Neo. He challenged Eira to a sword duel in front of other students. Jack's gravity magic made every step heavy, but his speed was lacking. Eira moved lightly, dodging each attack, and won without using any mana. The crowd fell silent. Jack's face darkened with humiliation.
Exams followed soon after. Eira, Neo, Lara, and Ryn studied late into the night. Lara struggled as always with her unstable mana, and Ryn buried himself in his notes and crafting designs. Neo learned quickly, her water magic smooth and controlled. After the exams, nobles hosted a formal party. Neo attended with Ken, while Lara went with Ryn. Eira felt out of place among silk and gold, and when he saw Neo dancing with Ken, something uncomfortable stirred in his chest.
He left the hall quietly and wandered into the garden, where moonlight spilled over flowers and stone paths. Lily sat there alone, her light green hair glowing faintly under the stars.
"Avoiding the noise?" she asked gently.
"Something like that," Eira replied. A soft melody floated from inside the hall. Lily stood and held out her hand.
"Dance with me." He hesitated.
"I don't know how." She smiled.
"Then I'll lead." They moved together slowly, flowers bending toward them as if listening. When the music ended, neither stepped away. Lily leaned forward and kissed him softly, a quiet moment beneath the moon.
When Eira and Neo later returned to the outskirts again during break, the world felt gentler once more. Lumi hugged them tightly. Peris smiled with quiet pride. Eira met Kara, Ethan, and Lior again, their warnings still fresh in his mind. Neo laughed with neighbors, helped in the kitchen, and walked beside him through familiar paths.
Whatever was coming, whatever darkness stirred beneath the world, this peace felt precious.
And Eira intended to protect it.
By the time Eira turned seventeen, the academy had stopped feeling like a school and started feeling like a pressure chamber. Half the year was now devoted entirely to theory — complex magic systems, monster ecology, dungeon structures, national law, and mana control.
While the second half would be focused on preparation for the national selection. Each school would send only twenty students forward. Everyone knew what that meant. Every class, every test, every sparring match felt heavier, sharper, and more competitive.
Students barely laughed anymore. Even Neo spent more time in the practice halls than in the garden. Lara struggled harder than ever to control her unstable mana. Ryn stayed awake most nights, sketching devices and refining tools. Even Lily, who had always seemed untouchable, now moved with a kind of quiet focus, her expression thoughtful, distant.
In the middle of this, Eira received another warning.
It came through Kara first, then Ethan, then Lior — careful words passed along through trusted hands. Something inside the academy was wrong. The twisted mana they had sensed before had not faded. It had grown stronger. Worse, the royal knights had started investigating quietly, without alerting the academy staff or the noble houses.
What they were searching for, no one knew.
Eira was asked to meet an undercover royal knight at the training grounds late at night.
He went alone.
The training grounds were empty except for a single student standing near the weapon racks. A boy from the student council, someone often seen beside Lily during formal events. His posture was relaxed, his expression mild.
"You came," the boy said.
Eira nodded slowly. "You're the knight?"
The boy shook his head. "No. I'm the mask." He met Eira's eyes. "The real one is hidden. I'm here so people watch me instead."
That alone made Eira tense.
"I needed to see you because your name keeps appearing," the boy continued. "Not officially. In patterns. In places where mana becomes unstable. In reports of dungeon shifts and student injuries."
Eira frowned. "You think it's me?"
"I think you're close to whatever it is."
Before Eira could answer, a soft voice spoke from behind them.
"I thought so."
They both turned.
Lily stood a few steps away, arms crossed lightly, her eyes sharp. "You're not who you pretend to be," she said to the boy. "And you're not just a student."
The boy sighed. "That was fast."
"She's been watching you," Eira said quietly.
"I watch everyone," Lily replied calmly. "It's my job."
The boy hesitated, then nodded. "Then you deserve to know. There have been other incidents. Students are separated in dungeons. Mana spikes. Injuries that shouldn't have happened. During the summer classes, three students were seriously hurt under similar circumstances."
Eira felt a chill. "Like what happened to us."
"Yes," the boy confirmed. "The teachers detected external mana in those cases, too. But it was buried."
"Why?" Lily asked.
"Politics."
Silence stretched between them.
"There's a trip next week," Lily said slowly. "A herb-gathering expedition. Open dungeon. All students and teachers. Three days of camping."
"That's the perfect opportunity," the boy said. "For someone to do something… quietly."
He handed Eira a small device. "This will send a signal if your mana spikes suddenly or if you're injured. It also tracks your position."
Eira accepted it. "You think something will happen?"
"I think someone wants it to."
After that, they separated quietly.
Lily and Eira walked back together through the quiet academy paths, the tension slowly easing into something softer.
"This is dangerous," Lily said.
"You came anyway."
She smiled faintly. "So did you."
They stopped near her dorm.
"You're bad at avoiding trouble," she teased.
"You're worse," he replied.
She laughed softly, then hesitated. "Thank you… for trusting me."
He nodded. "Thank you for not pretending to notice."
She unlocked her door. Her roommate was already asleep.
They stepped inside quietly.
For a moment, they stood too close, the room warm, the night quiet.
"You should go," Lily whispered.
"I know."
