I Transmigrated as Uzumaki Naruto, but This Is a Genderbent Naruto

After transmigrating into the world of Naruto, he becomes the protagonist, Naruto Uzumaki, and gains a Treasure Chest System. Before he can even shout his catchphrase about becoming Hokage someday, he discovers that the world he transmigrated into is anything but simple. How did Sasuke turn into a young lady? How did Itachi Uchiha become a cool, domineering beauty? And why are most of Konoha's Twelve Guardian Ninja girls? Even the Nine-Tails is...??? Could this be a genderbent Naruto world? After learning the truth about this world, Naruto Uzumaki decides not to become the Seventh Hokage. Instead, he sets his sights on becoming the King of the Harem and a master of time management. PS: The Highschool of the Dead arc is about to begin.
