I want to write a novel in which the protagonist is reincarnated as a slime with the 'Rimuru Tempest' template.
The protagonist can travel to other worlds.
The problem is, I haven't decided on a main world yet.
I came up with the idea of having the main world be the Fairy Tail world, but I backed down because if I wanted to write a novel featuring Fairy Tail, I'd start 400 years before the main story, when Irene is young.
(Reminder: The protagonist will be asexual at first, so it would be dangerous if I started with Fairy Tail, Erza will probably disappear if start...so I gave up on the idea of Fairy Tail)
I also have an idea for a main world that is a comprehensive anime world featuring an ordinary daily life without superpowers. The protagonist can travel to other worlds, and when they return, it's like taking a break in their everyday life, relaxing before starting the next journey— and so on.
Or make the main world is Danmachi?
Anyway, I don't have any ideas at the moment.
Do you have any ideas? Please help me.
