In this fanfiction, a really interesting plot could be that the character adopted in the Oni Village has some sort of hidden connection to the village's past. Maybe they are related to an ancient Oni Village hero or villain. As they grow up in the village, they start to uncover secrets about their heritage. This could lead to a journey of self - discovery, while also dealing with the normal Naruto - style ninja battles and rivalries. They might also have to prove themselves to the villagers who are initially skeptical of an outsider being adopted into their community.
Well, in a 'Naruto Oni Ogre Village Adopted' fanfiction, perhaps the main character is adopted because they possess a unique power that the village sees potential in.

They would need to grow stronger and prove themselves worthy of their new home.
It could be a young Naruto - like character, full of energy and determination.

Another possibility could be Sakura. She could be adopted into the village, perhaps because of her medical skills. In the village, she could learn new ways to combine her medical ninjutsu with the Oni Ogre's knowledge of natural healing.
