Just a little idea I had...
Naruto x To-Love-Ru:
Naruto is found by a stranger in one of the many forests surrounding Konoha after his daily escapade in the village celebrating his birthday alone and by himself cying trying to keep himself happy and such. The stranger being a kid themselves and unknowingly by Naruto, is a Princess of a far away planet feels a little bit of Naruto in themselves in the lonely department of familial love decides to bring Naruto home with them. After unknowingly saving the Princess from an assassination, the King gives Naruto the ok to stay in his palace. Later on in the story he gets adopted by the family and this is where the real story begins.
Elemental Nations is a hidden continent from the public but is known by the Country Leaders in the UN. It is the Bermuda Triangle surrounded by Navies from different countries to guard the border along with the barrier set up by the Sage of Six Paths from the agreement made by Kaguya and Japan. Will somehow make this work.
Now I just got this idea from reading some stories in the site where he gets abused then plans revenge, dies and reborn somewhere else, and such. I'm hoping that this story is gonna do great and we will see.
