Itachi Uchiha, beloved and respected in the magical world of Hogwarts was sitting in the grand hall, next to his wife Luna Lovegood, enjoying a peaceful dinner. That was, until an unexpected interruption.

Suddenly, a hooded figure appeared in the center of the hall. It was none other than Voldemort, the embodiment of darkness, who had come to cause havoc once again.

Itachi turned to Luna, mouth full of food, and pointed towards the dark figure. "Who's he?" he asked, his voice muffled. Luna put down her cutlery and replied, "That's the Dark Lord,".

Voldemort's voice echoed in the hall, "It's been so long hasn't it, Potter?". As the tension built up, Itachi, growing bored, blurted out, "Are you guys going to fight or kiss, which one is it?".

This shocked everyone, and the entire hall fell silent. Harry, shaken from his showdown with Voldemort, pulled himself together and managed to stammer out, "I-I'm the only one who can stop him, I'm the chosen one!".

But before Harry could act, Itachi's eyes transformed into red with peculiar patterns, then they shifted into a purple ripple pattern. "Universal Pull," he said calmly. Voldemort was instantly pulled towards him.

Itachi unsheathed a sword, more like a dagger, with an intricate design, and pointed it at Voldemort. With a swift motion, he sealed the Dark Lord within the blade. The students and staff of Hogwarts watched in awe.

The grand hall was silent until Itachi broke it. "There, I finished your job, Potter," he said, looking towards Harry. The boy who lived was dumbfounded and could only manage a weak, "Thank you, Itachi.".

Itachi slumped back in his chair, turned to his wife Luna, and said, "I'm just tired of snake people ruining people's lives.". Luna chuckled at her husband's complaint and kissed him on the cheek.

Harry, curious, asked him, "Wait, you had someone like Voldemort?". Itachi nodded and said, "Yes, his name was Orochimaru, he tried to steal my body.".

"So what happened?" Harry inquired. Itachi shrugged and said, "I cut his arm off." The hall erupted in laughter, and the evening that started with a dark interruption ended with a joyful chuckle.
