A fanfic about Ira and Rachel in Glitter Force Doki Doki could explore their relationship dynamic. Maybe it could start with how they first met. For example, they might have crossed paths during a battle against a common enemy. Ira, with his edgy personality, and Rachel, who is full of determination, could have an initial clash of personalities. But as the story progresses, they could come to understand and respect each other more. This could lead to them becoming stronger allies in the fight against evil in the Glitter Force world.
The plot could revolve around Ira's transformation. He could start off as a bit of a troublemaker in the Glitter Force Doki Doki world. Rachel, being a positive force, could be the one to try and reach out to him. She might see something in him that others don't. This could lead to a series of events where Ira slowly starts to change his ways, and Rachel is there to guide him. Their relationship could grow from a tentative acquaintance to a strong friendship, all while they face the challenges of the Glitter Force universe together.
First, you need to decide which other series or concept you want to cross over with. It could be another anime, a movie, or even a book. Once you've decided that, start thinking about how the two worlds will interact. For example, if you're crossing over with a different magical girl anime, how will the magic systems work together?
Another plot idea could be a time - travel crossover. The Glitter Force characters could travel back in time to a point where their predecessors (if there are any in the Glitter Force lore) were fighting a big battle. They could offer their help and in the process, learn more about their own powers and the history of the Glitter Force. This would also allow for some cool interactions between different generations of characters.
Another aspect of their character dynamics could be their competitiveness. They might compete in various Precure - related tasks, like who can defeat more villains or who can help more people. This friendly competition could add a layer of fun and excitement to the fanfic, while also strengthening their bond as they respect each other's abilities more and more.
The plot could involve their friendship evolving. Maybe Ira, who might initially be a bit of a troublemaker, starts to see the good in Rikka. They could go on adventures together in the Precure world, facing challenges side by side. Their relationship could grow from mutual respect to a deep, unbreakable bond.
There's no clear indication of its popularity without more research. It might be popular among fans of hybrid game - novel concepts. However, if it lacks proper marketing or if its content is too specific or not well - executed, it may not be widely known.
I don't think Doki Doki is bad. It has its strengths, such as creative characters and immersive atmosphere. But of course, different people have different preferences when it comes to visual novels.
