New Student, Familiar Aura
"Class," Iruka said, smiling stiffly, "we have a new transfer student from an allied village."
The door slid open.
A girl entered.
Petite. Jet-black hair. Crimson eyes. Dressed in standard Konoha attire, but her chakra pulsed oddly—like it wasn't hers.
"Introduce yourself," Iruka prompted.
The girl's voice was sweet, but flat.
"My name is Yuuki."
Raiden's heart skipped.
> System Alert: Subject Three Detected
Disguise Protocol: Active
Warning: Hostile/Neutral Alignment Unknown
Yuuki's eyes flicked to Raiden. For a brief moment, they burned with recognition.
Then she looked away.

Cracks in the Harem
Ino watched the new girl sit next to Raiden.
She didn't like it.
Not one bit.
She leaned toward Ayaka. "You feel it too, don't you?"
Ayaka nodded, threads twitching under her gloves. "She's dangerous. Like us."
"Then why is Raiden acting like nothing's wrong?"
"Because…" Ayaka glanced at him. "…He wants to forget."
Across the room, Hinata sat quietly. Her fingers gripped the hem of her shirt.
> "Another one… and she's beautiful. I can't compete…"

After School: Heart Games Begin
That afternoon, the girls confronted Raiden.
All at once.
Ino: "What's with the silent act? You felt it. She's not normal."
Ayaka: "You don't sense her chakra? It's identical to Subject Zero protocols."
Hinata (softly): "Raiden-kun… do you know her?"
Raiden looked at all of them, unreadable.
Then Yuuki approached from behind, placing a gentle hand on his shoulder.
"We were made together," she said quietly. "Weren't we, Raiden?"
The air tensed.

Meanwhile: Shiro's Smile Cracks
Elsewhere on the rooftop, Shiro watched the scene unfold.
His usual carefree smirk faltered.
"Subject Three, huh?"
He unwrapped a piece of gum, but didn't chew it.
> System Subprocess Detected: Class-X Memory Vault Engaged
Warning: Shiro's Core Alignment: Unknown
His eyes narrowed, glowing briefly with a strange black chakra.
"…Guess I'll have to step in soon."

Nightfall: Hidden Conversations
That night, Raiden stood at the Hokage monument, alone—until Yuuki appeared beside him.
"You don't remember it all yet," she said softly.
"I remember fragments," he replied. "And pain."
She looked up at the stars. "We were never supposed to escape."
Raiden turned toward her. "Why are you here now?"
Yuuki's smile was sad.
"To remind you what they turned us into."
Then she stepped closer.
"You think those girls like you for you?" she whispered. "They don't know the monster sleeping inside."
Raiden stared at her, unmoving.
"Do you?"
She kissed his cheek, barely a breath.
"Don't fall in love, Raiden. You'll only break them."
