sparking system champions book 1(futa/femboys shed harem X protagonists)

I like making crossover stories and I got a good idea after I played Dragonball sparking zero this is gonna be about a bunch of different protagonists some of them shares a harem other don't also despite what the title says it could be many different type of harem in this story also if you read it like the story you can be a part of it like creating your own oc for the story and if you give me a good idea I'll let people know you came up with the idea along with the oc if you give me a good idea for a character you might want in the story and with that being said the story is about A group of people who joined the rank of a secret group calling themselves the sparking what if masters those who are part of this group gain a power known as the sparking system this allows a person to go to completely different dimensions where a version of a anime might be real in that dimension or even a light novel might be real and they can use the power to make changes to that reality becoming a new born child once they become a member of sparking what if masters when they create their first character they get reborn as their character they created in one ever dimension they want to be in, they can create multiple characters, but they need sparking points to do so, and a lot of them find out more about this story by joining in the action by reading the book and giving this book a chance. Most stuff can be explained about the story by reading the book.
