Itachi Takes Over Longbottom: The Strongest Wizard in History

[Overpowered Protagonist] + [Harry Potter Fanfiction] + [Ravenclaw]

When the Impure World Reincarnation ended, Uchiha Itachi didn’t return to the spirit world he had imagined. Instead, he transmigrated into Neville Longbottom.

He soon discovered that magic in this world seemed even more fascinating than the power of the ninja world. The two had certain similarities: by changing their frequencies, they could resonate with one another, and magic could also be used to perform ninjutsu, though the results differed somewhat from the techniques he had known.

“How did my Summoning Jutsu call up a Thunderbird?”

“Expecto Patronum can summon Susanoo?”

“Can Occlumency resist genjutsu? Interesting...”

He decided to use ninjutsu to spark a small revolution in this magical world and give it a little shock.

Many years later, Uchiha Itachi, president of the International Confederation of Wizards, Grand Sorcerer of the First Class of the Order of Merlin, head of the Dawn Society, Chief Warlock of the Akatsuki, creator of “Magic,” and new headmaster of Hogwarts, gave an interview.

“Mr. Longbottom, how did you discover the method of casting spells with hand seals and invent ‘Magic’ as a new magical technique?”

“It’s a method from another world.”
