Issei Hyoudou is a central character. He is a perverted but kind - hearted high school student who becomes a devil. He has a strong will to protect his friends and the ones he loves.
It could be a new student who discovers they are born of fire. Maybe they were adopted and had no idea about their true nature until they start experiencing strange powers during their time at the Highschool DxD. This character would then be thrust into the world of devils, angels, and other supernatural beings.
One major difference is the pacing. The anime 'Highschool DxD Born' has to fit the story into a set number of episodes, so it might speed through some parts. The light novel can take its time. For instance, in the novel, a battle might be described over several chapters with detailed tactics, while in the anime it could be over in a few minutes.
Well, the anime 'Highschool DxD Born' is an adaptation of the light novel. The anime brings the story to life with vivid visuals and voice acting. However, the light novel often has more in - depth details, especially when it comes to the characters' inner thoughts and some of the more complex plot elements that might be simplified in the anime for the sake of pacing.
One interesting plot idea could be a new character born from the fire element who has unique powers that disrupt the balance in the Highschool DxD world. For example, they might be able to control a type of fire that is immune to the usual magic defenses. Another idea could be a story where the main character discovers a hidden history related to the 'born of fire' concept in the Highschool DxD universe, like an ancient prophecy or a long - lost clan.
Their relationship could develop further through shared challenges. For instance, if they face a really tough opponent together, they'll learn more about each other's strengths and weaknesses, and that can deepen their bond. Another way is through communication. If Issei starts to open up more about his insecurities and Rias does the same, they can become closer on an emotional level.
One idea could be a story where Issei and Rias have to face a new, powerful enemy that targets their relationship. Maybe an ancient demon who sees their bond as a threat to the traditional demon hierarchy. Another plot could be a time - travel story where they go back in time and have to deal with past events that could change their present relationship. For example, they might have to stop an event that would have otherwise led to their separation.
The relationships between the characters are also a big draw. Issei's harem, for instance, has different girls with unique personalities. Their interactions, like Rias's leadership and Akeno's playfulness, add depth to the story.
