The night splits open with chaos.

A blast of corrupted magic shatters a row of street lamps, sending sparks raining over the dimly lit street. Civilians scatter, screams echoing between the buildings. Ladybug and Cat Noir land in perfect sync—two silhouettes framed against the broken glow.

“Looks like this one’s ugly,” Cat Noir mutters, spinning his staff and stepping forward, voice dripping with his usual careless bravado.

He’s ready.

Until he sees you.

A figure moves through the smoke like a whisper of midnight—silent, precise, and absolutely breathtaking in the most dangerous way. Shadows cling to your body like living armor, rippling as if they’re listening to your heartbeat.

You dodge the akumatized villain’s next strike with fluid, unnatural ease. A twist. A leap. A burst of blackened light that explodes from your palm—knocking the villain back several feet.

Ladybug blinks. Cat Noir forgets to breathe.

“Who… is that?” Ladybug whispers.

He doesn’t answer.

Because the stranger—you—turns your head slightly, eyes gleaming through your mask. For a fleeting second, your gaze meets his. Cold. Sharp. Magnetic.

And something inside him shifts.

Something undeniable.

He drops from the ledge before he’s even aware he moved, landing beside you in a graceful crouch. His tail swishes behind him like he’s trying to calm his own heartbeat.

“Well,” he says, voice lower than intended, “if I’d known Paris had a new hero, I would’ve brought flowers.”

You don’t even look at him. You just murmur, cool and collected:

“You’re late, chaton.”

The word hits him harder than any villain.

He stands, eyes wide, mouth opening then closing. “Late? I—” His brain scrambles. “I was being dramatic! It takes time to be this charming!”

You’re already moving, shadows swirling around your heels.

He follows without thinking.

Together—yet completely uncoordinated—you take down the villain in a dance that feels too natural. Too synchronized. Too familiar.

He’s stunned by every movement you make. Every glance. Every breath.

When the villain is finally purified, Ladybug steps toward you.

“You’re new,” she says cautiously. “What do we call you?”

You stare at both heroes, unreadable. Then your voice rolls out like smoke.

“Nightshade.”

You turn without waiting for a reply—slipping into a dark alley where the shadows swallow you whole.

Cat Noir takes a step after you, as if compelled.

But you’re gone.

“Cat?” Ladybug nudges him. “Do you… know her?”

He swallows, throat suddenly dry.

“No,” he says slowly. “But… I think she knows me.”

THREE DAYS LATER

The classroom is warm and bright, sunlight spilling across rows of desks. Students chatter, Marinette stumbles over her own feet, Nino waves a hand dramatically as he retells a story no one asked for.

Adrien sits near the window, sketchbook open but untouched. He’s not drawing models today. He’s been sketching the same shadowy silhouette for three days straight.

Nightshade.

He doesn’t know why she’s stuck in his mind like a song he can’t shake. He just knows she feels… familiar.

The classroom door opens.

“Everyone, please welcome our new transfer student.”

Adrien doesn’t look up at first.

Until he hears the shift in the room—the quiet inhale, the confused whispers.

Then he lifts his head.

And his heart stutters.

You stand in the doorway, books pressed to your chest, your civilian clothes nothing like your hero attire—but your eyes…

Those eyes.

He’s seen them before. He just can’t place where.

You walk to an empty seat, the sunlight catching in your hair, your steps graceful but unassuming. Adrien finds himself staring—curiosity prickling beneath his skin. He doesn’t know you, but something about you pulls him in like gravity.

Nino elbows him. “Dude. You’re staring.”

Adrien tears his gaze away, flustered. “I—I wasn’t! I mean— I just thought she looked… familiar.”

“Familiar how?” Nino snickers. “Like you’ve seen her in a dream?”

Adrien forces a laugh, but it dies quickly when you glance back to him.
