Issei and an Otsutsuki - influenced Naruto could also be a great pairing. Issei's perverted yet brave nature combined with Naruto's powerful Otsutsuki - enhanced abilities would make for some comical and action - packed scenes. They could go on adventures together in the DxD world, facing off against various enemies.
Naruto and Rias could be an interesting pairing. Naruto's strong sense of justice and his Otsutsuki powers could complement Rias' leadership and devilish powers. They could work together to protect the DxD world from threats while also learning from each other's different ways of life.
One idea could be a crossover where Naruto's Otsutsuki powers somehow connect with the supernatural elements in DxD. For example, his ability to absorb and use chakra could be related to the magic in DxD. Maybe he could use his Otsutsuki powers to enhance the abilities of the devils or angels he meets in the DxD world.
Naruto and Rias could be a great pairing. Naruto's positive and determined nature would complement Rias' leadership and strong - willed personality. They could work together to protect their respective groups and also learn from each other's powers and cultures.
One potential pairing could be Naruto and Rias. Naruto's determination and strong will would pair well with Rias' leadership and powerful devil abilities. They could support each other in battles and in understanding the differences between their two worlds.
Naruto and Inuyasha would be an interesting pairing. Naruto's positive attitude and Inuyasha's more gruff nature could create some great character dynamics. They could learn from each other's fighting styles and outlooks on life.
Sakura and Liara would make an interesting pair. Sakura, with her medical ninjutsu skills, could collaborate with Liara, who is also very knowledgeable in the medical and scientific fields. They could exchange knowledge about different forms of healing and perhaps even come up with new techniques by combining their respective medical expertise.
Naruto and Cayde - 6 would be an interesting pairing. Naruto's energetic and positive personality would contrast with Cayde - 6's sarcastic and somewhat reckless nature. They could learn from each other, like Naruto teaching Cayde - 6 about the importance of friendship and never giving up, while Cayde - 6 could show Naruto some of his cool gadgets and weapons.
The combination of two very different universes. Naruto's ninja world with its jutsus and shinobi culture, and DxD's world of devils, angels and supernatural beings. It creates a whole new set of possibilities for stories.
Blake Belladonna and Koneko Toujou. Both are strong female characters with a bit of a mysterious side. Blake's Faunus heritage and her experience with the White Fang could be something that Koneko, with her Nekomata powers, would be interested in. They could bond over their similarities and differences, and perhaps team up in battles against common foes.
Griselda and Issei could make an interesting pairing. Their different personalities could create some fun and dynamic interactions. Issei's boldness and Griselda's more reserved nature could be a contrast that works well in a story.
Naruto and a wise, old swordsman. Naruto's energetic and determined nature would contrast well with the swordsman's calm and experienced demeanor. The swordsman could teach Naruto how to use a sword in combat, which Naruto would then incorporate into his own fighting style in a unique way.
