Power - up themes are common. For example, when a character from another series enters the 'Strike the Blood' world, they might gain new powers or abilities related to the vampire lore in that world.
Sasuke could also be an interesting crossover character. In the Strike the Blood world, his Sharingan and ninja skills would make him a formidable opponent. He could cross paths with the powerful vampires and might even form an uneasy alliance with some of them. His quest for power could take on a new dimension in this different universe.
One popular 'strike the blood crossover fanfiction' is the one that crosses it with another popular anime like 'High School DxD'. In this type of fanfiction, the characters from both worlds interact in interesting ways. For example, the vampires in 'Strike the Blood' might have to deal with the devilish politics in 'High School DxD'.
A third plot idea is a character - swap scenario. What if Kojou Akatsuki wakes up in the Naruto world with his vampire powers? He would have to navigate the world of ninjas, clans, and hidden villages. Meanwhile, Naruto could end up in the Strike the Blood world, having to deal with the complex politics between the different vampire factions while also trying to find a way back home.
One interesting Strike the Blood pregnant fanfiction could be about the challenges the characters face when a pregnancy occurs in the vampire - filled world. It might explore how the relationships change and how they protect the unborn. For example, in some fanfics, the male lead might become overly protective, adding a new dynamic to the story.

Yes. The Strike the Blood light novel has finished. There are no more new installments planned. It's a bit sad for fans who loved the series, but at least we have the complete story to enjoy.
Kojou Akatsuki is definitely a popular choice. As the main character, he has a lot of potential for different storylines. His complex nature as a vampire yet still a high school student makes for interesting character development.

This would allow for a lot of world - building and exploration of the vampire lore in the series.
