The plot of 'High School DxD Hero Light Novel' is centered around Issei. He has a lot of comical and action - packed experiences. For example, he has to train hard to become stronger in the devil world. Along the way, he makes allies and enemies. His relationships with the female characters, like Rias Gremory, are also a big part of the story. They have both romantic and strategic aspects as they fight together against different threats in the supernatural world.
Issei Hyodo is the main character. He is a reincarnated devil. Rias Gremory, a high - level devil and the president of the Occult Research Club, is also a main character.
In a Naruto and High School DxD fanfiction, there could be a scenario where the protagonists of both stories meet in a neutral dimension. Issei from High School DxD might be intrigued by Naruto's ninja skills and determination. Naruto, in turn, could be curious about Issei's Sacred Gear. They could start training together, sharing their knowledge and skills, and ultimately have to face a common enemy that threatens both their worlds.
There could be a really interesting fanfiction where the Queen of Blades from StarCraft gets inserted into the High School DxD universe. Maybe she could be a powerful new character in the school, causing all sorts of chaos or perhaps she teams up with the main characters to fight against a common enemy. It all depends on the creativity of the writer.
In a Naruto - High School DxD fanfiction, the power levels would be really interesting to explore. Naruto's sage mode and tailed - beast forms are extremely powerful. In the DxD world, there are different power systems like the Sacred Gears. It would be fascinating to see how Naruto's powers interact with the powers of the DxD characters. For example, could his Rasengan be enhanced by a Sacred Gear? Or how would he fare against a devil's magic?
The story mainly follows Issei Hyodo, a high school student who gets killed on his first date and is later resurrected as a devil. He then becomes part of the Occult Research Club at his school. There, he gets involved in various battles against other supernatural beings, all while trying to become stronger and also dealing with his new devilish desires and relationships with his female comrades.
One possible scenario could be that Naruto characters are somehow transported to the world of High School DxD. Naruto's ninjutsu skills would be quite a shock to the devils and angels in that world. For example, Sasuke's Sharingan could give him an edge in battles against the supernatural beings in High School DxD. And Naruto's never - give - up attitude might inspire some of the characters there to face their challenges more bravely.
