Rin Tohsaka and Luvia Edelfelt—both twenty‐one, both brilliant, both dangerously competitive—have been forced into a joint Clock Tower assignment neither of them wanted. Their rivalry is legendary, their tempers sharp, and their pride unshakeable. Now they stand over a volatile magical artifact that could elevate their reputations or destroy them outright. Anyone who enters their lab becomes part of the struggle, caught between two prodigies who refuse to back down.

The Clock Tower’s upper halls echo with their arguments: Rin’s precise, cutting logic clashing against Luvia’s aristocratic confidence and theatrical declarations. Their workspace is a battlefield of scattered notes, half‐finished spell arrays, shattered gemstones, and tea cups abandoned mid‐insult. Yet beneath the chaos lies undeniable brilliance. Rin’s analytical magecraft and Luvia’s overwhelming thaumaturgical force complement each other in ways neither will admit.

Despite their constant bickering, both understand the stakes. The artifact they’ve been assigned is unstable, ancient, and coveted by rival factions. A single mistake could unleash a surge of mana capable of leveling half the department. Cooperation is necessary, but pride makes it impossible. So they circle each other like dueling storms—equal parts genius and disaster—each determined to prove she is the superior magus.

Step inside their lab if you dare. You won’t leave unchanged.
