Naruto Universe !

The morning sun streams into the Hidden Leaf Academy classroom, but the warmth does absolutely nothing to calm the pure chaos inside. At the front, Iruka-sensei's face turns crimson, a massive vein throbbing on his forehead as he slams a textbook down.
"Naruto! Get down from there this instant!" he roars. Balanced precariously on top of the chalkboard, Naruto holds a bucket of bright pink paint, laughing hysterically.
"No way, Iruka-sensei! I'm practicing my stealth style!" he yells, nearly spilling paint onto Sakura in the front row. Sakura’s face twists into pure rage. "Naruto, you idiot! Move before I kill you!" she shrieks, before instantly melting into a sweet coo as she turns to Sasuke.

"Right, Sasuke-kun? He's the worst."
Sasuke doesn't look up. Propping his chin on his crossed fingers, his dark eyes radiate a cold, moody aura. "Hn. Annoying losers," he mutters, ignoring her completely. Nearby, Ino glares daggers at Sakura. "Hey, Billboard Brow! Step away from Sasuke-kun!" she snaps. Next to her, Shikamaru rests his head flat on his desk.
"Ugh... what a drag," he groans. "Shut up, I'm trying to sleep." Beside him, Choji loudly crunches on potato chips, unbothered by the screaming.In the back, Kiba laughs wildly as Akamaru pokes his head out of his jacket and barks. Hinata blushes furiously, her index fingers nervously poking together as she watches Naruto, terrified he'll fall. Shino sits completely still in the corner, sunglasses reflecting the room. Suddenly, the door slides open. A quiet hush drops over the room as eyes briefly glance toward the entrance. Iruka-sensei stops yelling and rubs his temples, fighting a massive headache. "Ah, a late arrival," he sighs heavily, gestures toward the rows of desks, and turns back to the chalkboard. "Just grab an open seat quickly so I can start this lesson before the classroom gets destroyed." Naruto waves from the chalkboard, Sasuke gives a cold glance, and the desks await a choice.
