The Great Hall in Hogwarts was buzzing with excitement. Itachi Uchiha, Deidara, Sasori, and Hidan, the heartthrobs of the school, had set up a real-life Gundam battle in the middle of the lunch hour.

Itachi was just finishing his lunch with his wife, Luna Lovegood, when Deidara shouted with glee, "Itachi, guess what? We managed to get Gundam Extreme VS. 2 Overboost to work!"

Itachi's eyes widened in surprise, "What, seriously!?" Deidara nodded, grinning from ear to ear. Luna, however, looked slightly confused and asked, "What's Gundam Overboost?"

Itachi explained, "Luna, it's a very popular arcade game we played in our world. You play in 2v2 or 4v4 piloting robots called mobile suits." Luna's eyes sparkled with interest.

Sasori and Hidan were already at the controls, eagerly waiting for Itachi and Deidara to join. "Itachi, hurry up so we can play," Hidan called out impatiently.

Students and teachers had begun to crowd around, their curiosity piqued by the unusual spectacle. Itachi selected his mobile suit, saying, "I'll choose Extreme Gundam Type Leos II Vs."

Deidara, Sasori, and Hidan also announced their selections. "Gundam Xanadu," said Deidara. "Gundam Vicious," said Hidan. "Gundam Supremacy," said Sasori. With that, the battle began.

Itachi and Deidara were pitted against Hidan and Sasori. The four Gundams began shooting, dodging each other's beams. The Great Hall was filled with the sounds of simulated combat and the cheers of the onlookers.

Ron Weasley, a close friend of Luna's, was among the spectators. He couldn't contain his excitement and shouted, "Hey, when you guys are done, let me try!" Itachi simply replied, "Sure."

As the game progressed, the crowd grew larger, with nearly every Hogwarts student captivated. The excitement was palpable. The Gundam battles had become the talk of the school.

Itachi's Gundam kicked Hidan's, sending it flying back. He then turned his attention to Sasori's Gundam, opening fire. His strategic moves were gaining him the upper hand.

Sasori and Hidan countered with a synchronized attack, but Itachi dodged their shots. He was in his element, expertly maneuvering his Gundam. Deidara was also holding his own against the opponents.

The battle was intense, with the teams evenly matched. Deidara managed to land a hit on Sasori, causing an explosion that sent Sasori's Gundam spiraling. The crowd cheered louder.

Hidan, seeing Sasori in trouble, charged at Deidara, but Itachi intercepted him. The two Gundams clashed, their swords sparking upon impact. It was a sight to behold.

Luna watched with wide eyes, her heart pounding. She had never seen anything like this before. The intensity of the battle was overwhelming and thrilling at the same time.

The battle was nearing its end. Itachi and Deidara were pushing their opponents back. Hidan and Sasori were struggling to defend. Itachi saw an opening and fired at Sasori's Gundam.

Sasori's Gundam exploded in a burst of light, signaling his defeat. The crowd erupted in cheers. Hidan, now alone, was quickly surrounded by Itachi and Deidara's Gundams.

Itachi and Deidara launched a combined attack on Hidan. Hidan tried to evade, but it was too late. His Gundam was hit and he was knocked out of the game.

The crowd erupted in applause as Itachi and Deidara emerged victorious. The Hogwarts students were completely taken by the spectacle of the Gundam showdown. It was a day they would never forget.

Luna ran up to Itachi, wrapping her arms around him in a congratulatory hug. Itachi smiled, glad that he could share this part of his world with her and the rest of Hogwarts.

Deidara, Sasori, and Hidan joined them, each wearing different expressions. Deidara was grinning, Sasori looked slightly annoyed, and Hidan was complaining about his loss. It was a moment of camaraderie.

Ron finally got his chance to play the game. He was clumsy at first but soon got the hang of it. He was having the time of his life, much to the amusement of the others.

The rest of the day went by in a blur of more Gundam battles. The students were hooked, and even some of the teachers tried their hand at the game. The Great Hall was filled with laughter and excitement.

Itachi looked around at the emptying hall, a smile playing on his lips. He was glad he had brought the Gundam game to Hogwarts. It had brought everyone closer and created unforgettable memories.
