Summary: This sort of follows episode 2 of Ouran High but very loosely.

Chapter 13: The Spring Masquerade

The music room had been transformed beyond recognition. Velvet drapes, crystal chandeliers, and golden candlelight bathed the space in an almost ethereal glow. Exotic flowers lined the tables, and soft orchestral music swirled through the air. Tonight, the Spring Masquerade Dance would be unforgettable — and not just because of its splendor.

Haruhi adjusted her mask nervously. The gold-and-white crystal piece Tamaki had insisted on was heavier than expected, but she kept her back straight. She had spent days preparing for this event, both as a Host Club member and as a pawn under the protection of the devils around her.

I just hope nothing goes wrong, she thought, fidgeting with the hem of her gloves.

Guests Arrive

The first waves of masked students entered, murmuring admiration at the extravagant decorations. Tamaki, as radiant as ever, flitted among them with a dazzling smile, introducing Haruhi as his “most valued aide.” The twins danced around them, teasing and whispering, while Honey bounced along with Usa-chan perched on his shoulder.

Kyoya, sitting off to the side with his usual unreadable expression, noted every detail of the guest list and magical wards, running subtle checks with a flick of his wrist. Mori, silent and imposing, moved like a shadow between tables, ensuring every aisle was secure.

Haruhi tried to focus on her role — greeting, assisting, keeping an eye on potential hazards. It was exhausting but exhilarating.

The First Sign

Halfway through the evening, Haruhi noticed it — a chill rolling through the otherwise warm ballroom, a ripple in the wards beneath the floor. Something—or someone—was observing, waiting for a weak moment.

She tugged at Tamaki’s sleeve. “Tamaki-kun…do you feel that?”

Tamaki glanced around, his golden aura flaring instinctively. “Hmm? Oh…perhaps a draft?” He smiled, but his fingers twitched, just slightly.

Haruhi narrowed her eyes. Not a draft.

The Attack

Suddenly, the lights flickered. Guests gasped. Shadows stretched unnaturally along the walls. From the balcony above, a black silhouette dropped silently, landing behind a cluster of students.

Before anyone could react, a strange figure lunged — not quite human, its limbs jagged, claws glinting under the chandeliers. One swipe and a decorative candelabra toppled, flames licking the edges of the drapes.

“Everyone, get back!” Haruhi shouted, stepping forward. She raised her hands instinctively. The familiar crystalline shields flared into existence, forming a protective dome around the nearby students.

The attacker hissed, claws striking at the barrier — but the force of the blows only made the shields shimmer brighter. Haruhi’s Sacred Gear pulsed, responding to her fear and determination.

Tamaki and the Club Respond

Tamaki’s aura erupted around him like sunlight breaking through storm clouds. “Haru-chan, step back! I’ll handle this!”

Hikaru and Kaoru sprang into action, their combined illusions confusing the intruder. Honey bounded ahead, Usa-chan clutched tightly, and Mori moved like a living weapon, striking precise blows to drive the attacker back.

The creature hissed and swiped again — but the combined force of the club’s powers and Haruhi’s shields created a barrier it couldn’t break. Sparks flew, petals scattered, and the chandeliers swung dangerously overhead.

Haruhi’s Moment

Something inside Haruhi clicked. She could feel the rhythm of the energy around her — the dance of her friends’ powers, the flow of her own Sacred Gear. She extended both hands and thrust forward. The crystalline force erupted outward like a wave, knocking the intruder off its feet and sending it skidding across the floor.

The figure dissipated into shadow, leaving behind only the faint smell of smoke and a few scorched petals.

Haruhi stood panting, heart hammering, as Tamaki rushed to her side.

“You…you did it!” he exclaimed, golden aura flickering with relief. “You saved them all!”

Haruhi blushed, lowering her hands. “I didn’t do it alone.” She glanced at the club. “We all did it together.”

Kyoya’s sharp voice cut through the moment. “No fatalities. Wards held. Minimal collateral. Acceptable.”

Tamaki, however, was less concerned with protocol. His gaze lingered on Haruhi, his face flushed. “Haru-chan…”

Aftermath

The guests, unaware of the true danger, applauded — mistaking the flashing shields and club teamwork for a spectacular special effect of the dance. Haruhi, Tamaki, and the others exchanged tired but triumphant smiles.

Yet somewhere in the shadows outside the academy walls, a figure watched. A voice whispered:

“So the pawn awakens…interesting.”

The game had begun.
