Who would be the most interesting character pairing in a 'High School DxD x Bleach' fanfic?

One possible plot could be that the characters from High School DxD end up in the Bleach universe. For example, Issei could be mistaken for a substitute Soul Reaper due to his high spiritual energy. He might then team up with Ichigo to fight against a new threat that is causing chaos in both the Soul Society and the human world. The devils from High School DxD could bring their unique powers to the table, like the ability to use magic and their different forms, which would add a new dynamic to the battles in the Bleach world.

Elizabeth from Nanatsu no Taizai and Rias from High School DxD would make for an interesting duo. Elizabeth is gentle and kind, while Rias is a strong and confident devil. They could have a great dynamic, with Elizabeth's compassion influencing Rias's more calculating nature, and vice versa. Another interesting combination would be Gowther from Nanatsu no Taizai and Akeno from High School DxD. Gowther's mysterious and emotion - analyzing abilities combined with Akeno's powerful and alluring personality would be quite a sight to behold.

Ichigo and Rias would be a very interesting pairing. Ichigo is a powerful and determined fighter, and Rias is a strong - willed Devil. Their personalities could clash at first, but then they might find common ground in their leadership roles and their desire to protect their respective groups.

Jiraiya would also be a great character in this fanfiction. His pervy yet wise nature combined with his knowledge of senjutsu could lead to some really funny and also some very deep moments in the story. He could interact with the characters in High School DxD in a unique way, perhaps teaching them some of his own skills or learning from them as well.

I think Sasuke and Issei could make for a great combination. Issei is all about power and his perverted nature adds a comical element. Sasuke, on the other hand, is serious and highly skilled. Their dynamic could be really fun to explore. Issei might be in awe of Sasuke's skills and try to learn from him, while Sasuke could be both amused and irritated by Issei's antics.

Definitely Naruto and Issei. Issei is all about perverted thoughts and power - seeking, while Naruto is more about friendship and protecting his comrades. Their interactions would be full of contrasts and they could learn a lot from each other.

Goku would be really interesting. His pure - hearted and naive nature would contrast greatly with the more complex and often morally ambiguous characters in High School DxD. He would see the battles and power struggles in a different light, probably just wanting to test his strength and have a good fight without getting too involved in the politics.

Ichigo and Sasuke would also make a great pair. Both are complex characters with a lot of power. They have a similar drive to become stronger and protect their loved ones. In a crossover, they could start off as rivals, constantly trying to outdo each other in combat. But as they face greater threats together, they could develop a mutual respect and perhaps even a friendship, sharing their combat techniques and knowledge of their respective worlds.

Gohan and Issei would be really interesting. Issei is all about being a pervert and getting stronger in his own way. Gohan is this powerful yet humble Saiyan. Their different outlooks on power and relationships would create a lot of humorous and thought - provoking moments.

Ben and Issei would be an interesting pairing. Ben is used to being a hero with his Omnitrix, and Issei has his own journey of becoming a powerful devil. They could learn from each other's combat styles. Ben could show Issei how to use his alien forms' unique abilities in battle, and Issei could teach Ben about the world of devils and the importance of relationships in his world.
