The development could be that Jaune, after being betrayed, is thrust into the DxD highschool harem scenario. He might first struggle to fit in, but as time passes, his unique qualities start to shine through. The harem aspect could add an interesting dynamic, where different characters are attracted to him for various reasons. His journey of self - discovery and growth in this new and wild environment would be a key part of the story's development.
Well, in such a fanfic, the story might develop with Naruto being betrayed in his original world and then somehow ending up in the DxD highschool setting. He could start off as an outcast due to his past betrayal, but gradually gain the trust and love of the harem members through his strong will and unique abilities.
Jaune is interesting in this fanfiction because his betrayal is a catalyst for change. He's not just some generic character in the DxD highschool harem. His past makes him more relatable as many people have experienced betrayal in some form. In the new setting, he has to re - evaluate himself and his values. He might be hesitant to enter into relationships with the harem members at first, but as he does, his character evolves. His internal struggle between his past pain and the new opportunities in front of him is what makes him a captivating character in this type of fanfiction.
In many fanfictions, Issei's character develops in terms of power. He starts as a relatively weak character and gradually becomes stronger through training and various challenges. For example, he might learn new techniques from a mysterious mentor or gain new powers from a magical artifact.
One thing that makes this type of fanfiction appealing is the contrast. Naruto, a character known for his loyalty, is betrayed in his own world. Then he's thrown into the DxD highschool where there's a whole new set of rules and relationships. The harem part means there are multiple characters with different personalities that can have various interactions with Naruto. It's also about seeing Naruto grow and change in this new environment, perhaps learning to trust again through his relationships with the harem members.
The plot may also involve the character trying to find a way to reverse the gender - bender if it was caused by some sort of magic or curse. Along the way, they might encounter other characters who are either helping or hindering them in this quest. And this journey can lead to the discovery of new powers or secrets within the highschool dxd universe.
In some fanfictions, Issei's character develops by becoming more mature. He realizes the consequences of his actions more deeply. For example, when he uses his powers, he starts to consider the collateral damage and tries to minimize it, which is a big step from his more impulsive self in the original story.
Another way her character develops is through her own self - discovery. Fanfictions often explore Gabriel's identity as an angel in a new light. She might question some of the strict rules and dogmas of the angelic realm. This internal struggle can lead to her evolving into a more complex and independent character. She may start to make decisions based on her own beliefs and values rather than just following what she was taught as an angel, which is a significant step in her character development.
In fanfiction, such a betrayal could occur due to power struggles. Maybe Rias sees Naruto as a threat to her position in the Highschool DxD world. She might fear his growing power and influence, which could overshadow her own. So, in order to maintain her status, she betrays him.
First, define the appearance of the Vritra Gear. Is it a piece of jewelry, a weapon, or something else? For example, it could be a gauntlet that gives the OC special powers. Then, think about how the OC got the gear. Was it inherited, or did they find it by accident?
First, you need to know the source materials well. Thoroughly understand the characters, settings, and rules in both Highschool DxD and the other series you want to crossover with. For example, if it's a crossover with 'Tokyo Ghoul', know how the ghouls' powers work and how they would interact with the devils in DxD. Second, focus on character development. Don't just throw the characters together randomly. Let their interactions change and develop them. For instance, if Issei meets Kaneki, they could learn from each other's experiences of being 'different' in their respective worlds.
