You can try to find them in some local libraries. Some libraries have a collection of Japanese light novels. Another option is to look for e - book versions on legitimate e - book platforms such as Amazon Kindle or BookWalker. They often have a wide range of novels available for purchase and download.
In my opinion, it is worth reading. The world - building in the novel is quite fascinating. It expands on the universe of 'Owari no Seraph' in ways that the anime might not fully cover. You get to understand the complex relationships between the characters better, and the writing style is engaging enough to keep you interested throughout.
One possible analysis could be that it allows for a more personalized take on the 'Owari no Seraph' universe. OC (original character) fanfictions often bring in new storylines and character dynamics. It might explore relationships between the existing characters in the series and the newly created OC in unique ways, such as a romantic relationship or a friendship that changes the course of the story.
It's mainly about the story in the 'Owari no Seraph' universe presented in a visual novel format. It likely involves the complex relationships between the characters, the battle against vampires, and the struggle for survival in a post - apocalyptic world.
One possible fanfic could be about Mika and Krul forming an unexpected alliance. Maybe they have to work together to face a common enemy that threatens both of their existences. In this story, Mika might start to see Krul in a different light, not just as a vampire but as someone with her own motives and desires.
One of the main themes is survival. The characters are constantly fighting for their lives in a post - apocalyptic world filled with vampires. Another theme is friendship and loyalty, as the characters rely on each other to face the numerous challenges. Also, there is a theme of revenge, especially for the main character who has a strong desire to take revenge on the vampires for what they have done to humanity.
