Perhaps a fanfiction where the reincarnation is not just a simple rebirth, but a merging of different timelines. So, the characters have memories and abilities from multiple versions of themselves across different reincarnations. This could lead to some really unique power combinations and story developments.
Another interesting concept could be a reincarnation where the roles are reversed. The Spirits are reborn as normal humans, and the main character, who was once a human dealing with Spirits, now has to help them adjust to their new human lives and protect them from threats that come with being human, like other humans' prejudices.
One idea could be that the main character has memories of their past lives and uses that knowledge to change the fates of the Spirits in a more positive way. For example, they might be able to prevent some of the more tragic events that usually occur in the original story.
Another interesting OC could be a spirit who has the ability to communicate with animals. This OC could bring a whole new dynamic to the story as she tries to understand the human world through the eyes of the animals she befriends. She might also use her animal friends to help Shido in his missions, like having birds spy on the AST or something.
One idea could be exploring an alternate universe where the Spirits and the main character have different initial meetings. For example, instead of meeting in a battle - like situation, they meet in a peaceful school event. Another plot could involve a Spirit who has lost her powers and the main character has to help her regain them without using the usual methods. It could lead to a whole new adventure and deeper understanding between them.
One idea could be exploring an alternate universe where the spirits have different powers and relationships. For example, making Tohka have the power to control time and seeing how that changes her interactions with Shido. Another could be a story focused on the backstories of the spirits before they became spirits, like what Kurumi's life was like as a normal human. Maybe a fanfic where Shido has to go through a series of trials to prove his love for the spirits in a more extreme way than in the original story.
One idea could be that the protagonist travels back in time to prevent a certain spirit from becoming a threat in the first place. Maybe they change a key event in the spirit's past that alters their future path.
A plot idea could be that a powerful Spirit in Date A Live is somehow transported to the Naruto world. This Spirit's power causes chaos, and Naruto and his friends have to figure out how to send it back. Along the way, they discover that the Spirit has a tragic past similar to some of the characters in Naruto. This leads to an unexpected bond between them.
The plot twists in the Date A Live light novels are quite something. It's not just about the protagonist, Shido, sealing the spirits. There are deeper conspiracies and relationships that unfold as the story progresses. The way the different timelines and alternate universes are sometimes hinted at adds an extra layer of mystery.
It's a visual novel related to the 'Date A Live' series. It likely focuses on the character Rio and her reincarnation story. Usually, in such visual novels, there are various plotlines including character development, relationships, and the exploration of the fictional world.
Begin by creating an outline. Outline the main plot points, such as how the reincarnation occurs, who is affected, and what the ultimate goal of the story will be. You could start with a character suddenly having strange dreams or memories that hint at their past life. Then, start writing the opening scene. It could be a normal day in the 'date a live' world until something triggers the realization of reincarnation.
One idea could be a story about a spirit learning about the concept of family from the human characters. She could start to see them as her own family and they could have heartwarming moments together like celebrating holidays or birthdays.
One interesting idea could be a Pokemon reincarnating as a different species and having to adapt to new abilities and instincts. For example, a Pikachu reincarnating as a Squirtle would have to learn how to swim and use water - based attacks.
