Luna Lovegood was known for her dreamy disposition, but lately, her attention was drawn towards one particular student in Hogwarts, Itachi Uchiha. He was unlike any student Hogwarts had ever seen.

He had come from a distant land, one where wizards and witches did not use wands. Not only was this intriguing to the Hogwarts students, but it was almost unbelievable.

One day, during Defense Against the Dark Arts class, Professor Lupin decided to delve into the mysteries of Itachi's magic. The class's anticipation was palpable.

"Are you sure you want to know?" Itachi asked, his eyes reflecting a hint of concern. Lupin, ever curious, encouraged him to give a demonstration.

Itachi solemnly nodded, put his hands together and uttered, "Curse technique amplification: blue & curse techniques reversal red." His voice echoed through the silent room.

Two hues sprung from Itachi’s hands, one blue and the other red. The colors swirled, mingled, and became a deep, mesmerizing purple. He called it “Hollow purple.”

With a flick of his middle finger, he sent the orb spiraling across the room. The orb vaporized everything in its path, leaving everyone stunned.

A moment of stunned silence followed. Then whispers broke out. "Voldemort..." someone said. Hearts skipped beats and voices hushed. Had the Dark Lord been lurking nearby?

"Itachi, you… you killed Voldemort!" gasped Draco Malfoy, his face pale. The room basked in an eerie silence once more as everyone processed Draco's revelation.

"Who?" Itachi asked, looking genuinely confused. As if it was just another day at Hogwarts. As if he hadn’t just casually demolished a mountain and vanquished the Dark Lord.

Hermione, Ron, and Harry, who had been silently observing the commotion, exchanged shocked glances. This was an unpredicted turn of events, even for them.

After that day, Itachi Uchiha was no longer just the new student. He was a force to be reckoned with, a mystery wrapped in an enigma.

Word spread across Hogwarts like a wildfire. The boy who killed Voldemort, without even knowing who he was. Who was he? Where did he come from?

Luna Lovegood didn’t care about all that. She just wanted to know more about Itachi, the boy behind the powerful magic. The boy whose sadness matched her own.

He was like a book she wanted to read but couldn't find. And the more she tried to understand him, the more she found herself falling for him.

For others, Itachi was the boy who had inexplicably killed Voldemort. But for Luna, he was just Itachi - mysterious, quiet, and inexplicably attractive.

Itachi, on the other hand, remained an enigma. Despite the newfound fame and attention, he remained as aloof and mysterious as he had been since his arrival.

Hermione, Ron, and Harry continued to keep a close eye on Itachi. The events of the DADA class had left them with more questions than answers.

They had defeated one Dark Lord already and had now involuntarily stumbled upon another powerful wizard. They couldn't afford to let their guard down.

Professor Lupin, however, saw Itachi's depth. He saw past the supernatural strength to the young man carrying unspoken burdens of his own.

Lupin knew that being the center of attention and rumors could be taxing. After all, he himself had been a subject of scrutiny before.

As the days passed, the shock began to wear off and life at Hogwarts started to return to normal. But the memory of that day remained vivid.

Itachi continued to bond with his classmates, sharing his unique magic, and occasionally showing glimpses of his true power. But he was always careful not to cause any harm.

Luna, Hermione, Ron, and Harry couldn't help but marvel at the power and grace that Itachi possessed. Yet, the greatest mystery was still the man himself.

The story of the boy who had killed Voldemort unknowingly and could destroy mountains began to fade, but the legend of Itachi Uchiha had just begun.
