The lights of the Dusk mansion remained lit long after night had fallen. Duke Dusk watched as the blue moon reflected on the tall windows of his estate. Between his fingers, he held an unopened letter — the seal of the Temaki family still intact.
"He dares ignore a direct summons?" the duke muttered, his voice firm and cold. He walked to his marble desk, placing the letter atop it. "If young Lucien believes he can toy with the name Dusk, he's mistaken."
A servant approached silently and bowed.
"Shall I prepare the meeting, my lord?"
"Yes," the duke replied. "Send word to the Temaki patriarch. I will tell him personally that the engagement between our houses is at risk."
The servant bowed again and vanished into the dim hallway. The duke remained still for a while, eyes fixed on the pale light of the moon.
'Elara… my daughter. What choices are you about to make?'
The blue moonlight painted the sky as carriages began to arrive at the grand hall of Astraea Academy. Students from every class — from S to D — gathered at the marble stairs, dressed in elegant attire. The long-awaited event had finally come: the Blue Moon Ball, the first celebration of the academic year.
Arven stood before the mirror in his dorm room, nervously adjusting the collar of his new suit.
'Does this even look right? I've never been to a ball before…'
He took a deep breath, trying to calm the restless feeling twisting in his chest. At eight o'clock, he descended to the main entrance, where a carriage adorned with the Dusk family's crest — a blue lotus — awaited.
Standing before it was Elara, wearing a flowing silver-blue gown that shimmered under the moonlight.
"You're right on time," she said with a faint smile. "I thought you'd be late."
Arven scratched his neck, avoiding her gaze. "I just didn't want us to miss the beginning."
She studied him briefly, then opened the carriage door. "Let's go."
The ride was silent for a few moments. Arven struggled to find the right words, the weight of the evening pressing on him.
"Nervous?" she asked, crossing her legs as she looked out the window.
"A little," he admitted. "I've never been to something like this. What about you?"
"I've attended balls since I was a child," she replied calmly. "But tonight… feels different."
'Different how?' Arven thought, but didn't ask aloud.
The grand hall was breathtaking. Crystal chandeliers reflected the blue glow of the moon, and velvet drapes hung between golden arches. Musicians tuned their instruments in the corner, filling the air with anticipation and the faint scent of magic.
Elara and Arven entered side by side, drawing curious glances. Whispers followed them — the Dusk heiress had arrived, but not with her fiancé.
"Well, look who decided to show up together," said a cheerful voice behind them. Lyra, wearing a lilac dress and her usual mischievous smile, approached with Kael — her fiancé — in a pristine white suit.
"You two look amazing," Lyra said brightly. "Elara Dusk and Arven… who would've guessed?"
Kael chuckled. "So the rumors were true. You're going to the ball together?"
Elara raised an eyebrow. "Is there a problem with that?"
"No, of course not," Kael said quickly, clearly embarrassed. "Just… unexpected."
Arven stepped in to shift the mood. "You've been here long?"
"Not really," Lyra replied. "But I'm curious to see the student council president. They say she's incredible."
Moments later, the hall lights dimmed. A figure of striking poise stepped onto the stage — golden hair, calm yet commanding eyes.
"Good evening, students."
The voice of Ana Pendragon, president of the student council, carried through the hall with effortless authority.
"It is with great honor that I welcome you all to the Blue Moon Ball. May this new year be marked by learning, growth, and the bonds we build along the way. Enjoy this night — it marks the beginning of our journeys."
The crowd erupted in applause. Ana gave a graceful bow before leaving the stage. As she walked past, Arven's gaze lingered on her — he could feel her mana, dense and powerful, radiating like a silent storm.
'Incredible… she's almost on par with an A-rank Hunter.'
Ana's eyes met his for a fleeting second, and she smiled faintly before disappearing into the crowd.
The music began. Couples filled the dance floor as candlelight shimmered across the polished marble. Lyra grabbed Kael's hand and pulled him to the center.
"Let's dance before the first song ends!"
Kael laughed, letting himself be dragged along. "You always take the lead, don't you?"
Arven and Elara stood nearby, watching. For a moment, silence returned between them — but this time, it felt comfortable.
"Would you like to dance?" Elara asked, her tone teasing.
"I… don't really know how."
"Then it's time to learn." She extended her hand.
He hesitated, then took it. Her touch was soft but sure. As the melody guided them, Arven's movements grew less awkward.
"It's not that hard, is it?" she said.
"Depends on who's teaching."
Elara looked away, a faint blush coloring her cheeks.
As they danced, several students turned their heads — including Lucien Temaki, who had just arrived, arm in arm with Gabriella Asumi. His smile was thin, empty.
"So that's how she forgets about her engagement?" Gabriella murmured.
Lucien's eyes followed Elara across the room. "She's just trying to provoke my father. But if he reacts, she won't be the only one to face the consequences."
Gabriella frowned. "You really mean to end the engagement, Lucien? You know what that could do to our families."
"If that's the price for being with you," he said quietly, "so be it."
She looked down, her heart heavy. 'I'm not sure I can bear the weight of that…'
Outside the academy, the wind grew colder. The blue moon gleamed brighter, its light stretching across the forest beyond the walls.
In the mist, something moved.
Dark, humanoid shapes slithered through the fog — their bodies made of living smoke, their eyes glowing white.
"It's almost time," one whispered. "The Dusk blood must be taken."
"The ball will serve as the perfect distraction," another replied. "No one will notice until it's too late."
The shadows melted into the darkness, drawing closer to the academy.
Inside, Elara smiled, unaware of the creeping danger. Arven, however, felt a chill crawl up his spine — an invisible presence pressing against his senses.
'That feeling again… this isn't normal.'
The music swelled. The blue moon bathed the hall in light, beautiful and silent — a silent witness to the beginning of something far more ominous.
