Warrior from other dimension

What if during fight with Sasuke in mission to retrieve Sasuke back to Konoha, Naruto was teleported to other dimension when his rasengan and chidori came in contact with each other creating tear in dimension which sucked Naruto in. He came into unknown land lost, not knowing what to do. Eventually he found his path in life in there and decided to not think of Konoha anymore. He befriended Kurama and learned everything he knows about chakra from him. He also learned how to use spiritual side and created techniques such as Hado, Bakudo, Flesh Step, Sonido, Cero. He even found cursed demonic blade called So'unga which contained the spirit of an ancient evil dragon from the depths of Hell. He slayed many demons who were rampaging across land saving humans and decided to unite this land. During his travels he met goddess Amaterasu, goddess of Sun, and after getting to know each other have fallen in love and married. Amaterasu gave to Naruto divine blade Kusanagi no Tsurugi, Yata no Kagami and Yasakani no Magatama while Naruto named this country Japan, Land of Rising Sun, in her honor. They had one son together and when Naruto was on his deathbed, he gave throne and three sacred regalia to his son. And with that Naruto Father, Lord, Hero and Protector of Japan died with Kurama following him not wanting to leave his best friend. Many years later he was summoned in Holy Grail War, but what he never expected was that he will find people from his old dimension. It will be interesting.
