There could be a fanfiction where the futa female character and Koneko team up against a common enemy in the DxD universe. This would likely involve some action - packed scenes and strategic planning between them. Maybe they also learn something new about each other during this time, like different powers or hidden abilities.
One popular story might be about Koneko's adventures in the DxD world with a futa female character added to the mix, perhaps involving a new quest or relationship. Another could be centered around how the futa female character influences Koneko's development in the story.
To write a good fanfiction in this area, it's important to focus on character relationships. Show how the futa female and Koneko interact, whether it's through friendship, rivalry, or something more. Also, use the DxD setting to your advantage. Incorporate the unique elements of the DxD world like the different factions and their politics. Don't forget to add some action or mystery to keep the readers interested. For example, they could be on a mission to solve a mystery that has to do with a powerful artifact in the DxD world.
One popular plotline is the male reader being a new transfer student at the school. He catches Koneko's attention, perhaps because he has a unique power or a kind heart. They start off as friends, gradually getting to know each other's pasts. Another plot could be that the male reader is involved in a dangerous situation, and Koneko has to protect him. This leads to them growing closer as they face challenges together. There are also plotlines where they start off not getting along well, but over time, they develop feelings for each other through various comical and heartwarming interactions.

Adventure and battle themes are quite common too. Koneko is a part of the Highschool DxD world which is full of supernatural battles and adventures. Fanfictions might take her on new quests, or have her face stronger enemies, all while she tries to uphold her values and protect those she cares about. This can make for some really exciting and action - packed stories.
