Harry discovers that Lily Evans was adopted, and her biological mother came from Japan with the surname Uzumaki. After tracking down the address he got, Harry encounters a portal and, seeing that he had enough of Wizarding World (this is post-Harry Potter and the Order of the Phoenix), went into Elemental Nations. Enjoy Harry's brotherly (cousins) with Naruto, Harry opens up a repair shop by secretly casting Reparo and his friendship with the Naras. No OP/Mary Sue Harry, even with his occasional talks with Danzo.
