Well, in such a fanfiction, one can expect a lot of interesting plot twists. Issei getting Riser's peerage would likely change the power dynamics in the High School DxD universe. It could lead to new alliances and rivalries. Maybe Issei would have to deal with the loyalty issues of Riser's former servants. Also, there might be a whole new set of training and growth arcs for Issei as he tries to master and utilize the new members of his peerage.
Obviously, Harry and Riser are the main characters. Harry, the well - known wizard from the Harry Potter series, and Riser, who is likely from another fictional universe or a unique creation within the fanfic.
Searching for 'Issei Gets Riser's Peerage' fanfiction can be a bit of a hunt. First, definitely check Fanfiction.net. It has been around for a long time and has a huge database. However, the site's search can be a bit finicky, so make sure you use specific keywords. AO3 is also great. It has a more organized tagging system. You can look for tags related to High School DxD, Issei, and Riser's peerage. Additionally, keep an eye on social media groups dedicated to High School DxD. Sometimes fans will post links to their fanfictions or recommend good ones there.
One interesting plot point could be the different magical abilities that Harry and Riser bring to their conflict. Maybe Harry's unique spells from the Hogwarts tradition contrast with Riser's more demon - related powers.
A possible plot for a Naruto vs Riser Highschool DxD fanfiction could be that there's a power imbalance in the Highschool DxD world that Naruto is brought in to fix. Riser, who is used to being in control, doesn't like this new factor. Naruto, being the hero he is, tries to resolve things peacefully at first. But when Riser challenges him, they engage in a battle. The fanfiction could then delve into how their different power systems work together, how Naruto uses his chakra in this new magical setting, and how Riser tries to counter Naruto's unpredictable moves. It could also be about how the two grow as characters through this encounter.
In a Naruto vs Riser fight in a Highschool DxD fanfiction, Naruto would likely win. Naruto has a vast array of powerful jutsu like the Rasengan and Shadow Clone Technique. He's also incredibly resilient and has great combat experience. Riser, while strong in the Highschool DxD universe, doesn't have the same level of combat versatility as Naruto.
There could be a storyline where Issei challenges Goku to a friendly sparring match to test his own limits. As they fight, they exchange techniques and learn from each other. This could lead to Issei unlocking new forms of his own power, inspired by Goku's Super Saiyan forms. And Goku could also gain new insights into combat from Issei's more unorthodox fighting style.
It depends on the rules set in the fan - fiction. If it's a battle based on strategy, Issei might have a chance. He has shown to be quite cunning in his battles. But if it's a pure power - based fight, Goku has the upper hand. His years of training under various masters and his Saiyan heritage give him an edge. Also, Goku has experience fighting opponents much stronger than himself and finding ways to overcome them.
In the beginning, Naruto and Riser may not get along well due to their different personalities and upbringings. Naruto is more down - to - earth and values friendship and justice, while Riser is more prideful. But when they discover they are brothers, they are forced to interact. As they spend time together, they realize they have more in common than they thought. For example, they both have a strong sense of protectiveness towards their loved ones. This realization could lead to them gradually building a strong relationship. Naruto might even start to understand Riser's pride as a form of self - confidence, and Riser could come to admire Naruto's selfless nature.
A great fanfic idea could be that Rias and Riser are sent on a joint mission to the human world. They have to blend in as high school students. This would be a comical and interesting premise as they struggle to adapt to human life while also dealing with their own relationship. Rias might be more empathetic towards humans, while Riser could be more arrogant at first.
