Perhaps there could be a storm - wizard or a shaman who adopts Naruto. This character would have deep knowledge of storm - related powers and would be the one to guide Naruto in his new journey.
Well, it could be about Naruto being taken in by a powerful storm - like entity or perhaps a group that has some connection to storms. Maybe they teach him new jutsu related to storm powers.
Obviously, Naruto and Ayame are the main characters. Naruto, the young ninja with a big heart and lots of energy. Ayame, the kind - hearted woman who runs a food establishment in the village. There might also be other characters like the regular customers of Ayame's place who could interact with Naruto and play a role in his new life.
An elf who adopts Naruto could be a main character. This elf might be an elder with great wisdom and magical powers. They see something special in Naruto and take him under their wing. Another character could be an elven child who becomes Naruto's friend. They teach each other about their respective worlds and grow together.
Gaara could be a main character. Since Naruto has a connection with him already, Gaara could play a big role in helping Naruto adjust to life in Suna. Maybe he becomes like a brother to Naruto in this new setting.
Obviously, the Jedi who adopt Naruto would be main characters. For example, a Jedi Master like Obi - Wan Kenobi could be the one to discover Naruto and take him under his wing. Another could be Yoda, who would be very interested in Naruto's unique abilities and would play a role in his training. There could also be other young Jedi trainees who become Naruto's friends or rivals during his time at the Jedi temple.
The main characters are Naruto, the young and energetic ninja, and Sarah Kerrigan. Naruto has his own set of friends and enemies back in his ninja world, but in this fanfiction, his relationship with Kerrigan is central. Kerrigan, who might have her own group of followers or allies, now has Naruto in her care. Their interactions, how Naruto adapts to Kerrigan's world and how Kerrigan guides Naruto, form the core of the story.
Definitely Naruto and Grayfia. Naruto is the main protagonist who has his own story and growth arc. Grayfia is the one who changes Naruto's life by adopting him. She could be a noble or a powerful mage. There may be other characters such as servants or comrades of Grayfia who are initially skeptical of Naruto but later come to accept him. And of course, there could be antagonists. Maybe there are some rivals in Grayfia's world who don't like the idea of an outsider like Naruto being in their midst and they try to cause trouble for him.
Naruto and Rias are bound to be the central characters. Naruto with his determination and power, and Rias with her leadership and magic. But we can't forget about the other members of Rias' peerage. They might have different reactions to Naruto being adopted. Some could be welcoming, while others might be a bit skeptical at first. And Naruto's own comrades from Konoha might also be relevant, perhaps in flashbacks or if they somehow cross over into Rias' world.
The Raikage, Ay, would also interact with Naruto. He might be hesitant at first about Killer Bee adopting Naruto, worried about potential problems. But as Naruto shows his strength and loyalty, Ay could start to see Naruto as an asset to the village. And of course, Naruto's friends from the Hidden Leaf Village might come to visit or have some sort of communication with him, like Sakura and Shikamaru. They could be worried about Naruto living in a different village but also be proud of his new experiences.
It could be a young Naruto - like character, full of energy and determination. Maybe an orphan who has always dreamed of becoming a great ninja and sees the adoption in the Oni Village as a new start. Or it could be a side character from the original Naruto series who for some reason ends up in the Oni Village and gets adopted there.
