The Extra is a Genius!?

Moonlight slipped quietly through the open window, painting soft silver lines across the polished stone floor of Noel’s dorm. Unlike the standard quarters, the rooms of Class S students were crafted with refined materials—smooth marble-veined tile, enchanted wood paneling, and insulation spells woven into the walls. Cool in winter, but tonight, the summer heat had broken through.

Noir padded across the floor in her small foxlike form, claws clicking gently against the stone as she searched for the coldest spot. Her fur fluffed outward in irritation. She sniffed, turned once, then collapsed with a tired grunt near the edge of the room, clearly uncomfortable.

"Too hot, huh?" Noel said from his seat by the window, shirt half-open, still damp from training earlier.

He reached out lazily and murmured, "Cooling Veil."

A soft shimmer of pale mist spilled from his fingers and settled over Noir’s body. Instantly, she relaxed—her fur flattened, her muscles slackened. She rolled over onto her back, letting out a long, satisfied exhale.

"Glad that worked," Noel muttered. "Thanks, Selene."

The room went quiet again.

After a minute, Noel tilted his head and looked at the now-sleepy wolf. "Noir... can you shift into your adult form now? The real one."

Noir’s ears perked. She rose to her feet, gave a quick shake of her body, and in one smooth wave of mana, her form began to expand. Her sleek body stretched, limbs lengthened, fur shimmered like liquid shadow—until a massive, lupine beast stood where the small creature had been.

She filled the space instantly. Her ears nearly brushed the arched ceiling. Her tail swayed slightly, knocking a chair out of place.

Two meters thirty.
