What are some interesting plot ideas for Highschool DxD Koneko fanfiction?

A plot could involve Issei and Koneko getting trapped in an alternate dimension. In this dimension, they have to find a way back home while also dealing with the strange creatures and rules there. This forces them to rely on each other more than ever and could spark a romantic relationship as they fight for survival.

One plot idea could be that the OC is a new transfer student at the school and has a special power that Koneko is initially suspicious of. As they are paired up for a school project, they start to understand each other better. The OC could be from a different supernatural group, and through their interactions, they help bridge the gap between their respective groups in the Highschool DxD universe.

One plot idea could be Koneko adjusting to the high school life which is a mix of Naruto and Highschool DxD elements. For example, she might have to deal with different types of jutsus in the school setting as well as the devilish powers from Highschool DxD. Another could be her forming an unexpected friendship with a Naruto character, like Naruto himself, and they learn from each other's powers and cultures.

One interesting plot could be about Koneko forming a stronger bond with the main character outside of the regular events in the original series. For example, they might go on a quest together to discover a hidden power within Koneko.

A simple plot could be that they compete in a school - wide tournament. Koneko's pride as a Nekoshou and Issei's determination to prove himself make for an interesting dynamic. They both face tough opponents and along the way, they offer each other advice and support, gradually becoming closer friends.

In fanfiction, Koneko is often depicted as a strong - willed character. She is known for her loyalty to her friends and her determination in battles.

A plot could also focus on a new character who is a hybrid of the two universes. They have the powers of both a devil from High School DxD and a wizard from Harry Potter. They struggle to find their place in either world as they are too different from the norm in both, and they embark on a journey to create their own identity and purpose.

One idea could be exploring new power-ups for the characters. For example, Issei could discover a hidden ability within his Boosted Gear that allows him to time - travel briefly during battles, adding a new strategic element. Another could be focusing on the relationships in the future. Maybe Rias and Issei have a family and the story could revolve around their children's upbringing in the supernatural world.

One idea could be a new character joining the school who has a unique supernatural ability that no one has seen before. This could disrupt the existing power dynamics and create all sorts of interesting interactions and challenges.

One idea could be to have a new character enter the world of Highschool DxD who challenges the existing power hierarchy and calls out the flaws in the main characters' actions. For example, this new character might see Issei's pervy ways as not just a comical trait but something that is disrespectful to the female characters and start a movement to change the way things are done in the school.
