I'm in Naruto, but the system says I'm in One Piece.

Good news! I've been transported to Naruto, Minato is my best buddy, and the system reward is the Rumble-Rumble Fruit! A perfect start! But the mission is to find Monkey D. Luffy??? Luffy is in this ninja world?! Until one day, Hoshino Yu saw a person wearing a straw hat at the Ninja Academy… and his ninja career completely went astray: building rafts in the training grounds, recruiting navigators and snipers at the school, even planning to "set sail" from the Land of Fire. Seeing the system classify the Fourth Shinobi World War as the "Marineford War," Hoshino Yu silently accepted reality. Years later, the history of the ninja world had long since deviated from its course because of him. Orochimaru became the Fourth Hokage, and the Akatsuki organization embraced peace. The Fifth Hokage, Minato Namikaze, and his family were reunited, the Uchiha clan entered the core of power, Jiraiya attended Naruto's wedding, and "Luffy" was pursuing his One Piece… This absurd voyage was heading towards a completely different ending.

Luffy*, *Naruto: Nobody Knows the Rumble-Rumble Fruit Better Than Me*, and *About My One Piece Mission in the Ninja World*.
