Sorry, I don't understand what fantasy is. When children were young, they liked to make up stories about princes and princesses. The time was usually a long time ago, and the location was usually a distant country. As for the protagonist, there was always the child's own delusion in it, even if he or she was not beautiful, handsome, smart, or brave. In the story, there is always a big dragon who kidnaps the princess - the dinosaurs are not extinct, they all become actors.
In terms of genre, I can only fill in fantasy.
Just a loose story. The demonic world, which is opposite to the human world, has its own laws of operation, and it is not something you can just turn into bread and eat. It would be much easier to write about the intersection of two girls' destinies in an unfamiliar environment.
There is some element of fantasy and some element of love. I don't like pure love stories, just like when I read comics, I like the vague love in shonen comics, such as Genkai and Toguro Ludi, Shizuru and Sakyo, Sendō and Rukawa (sweat... Long live Senryu!) Love is not everything, and it is not that beautiful, although I have not been in love yet.
I said that a person is usually happier. When you are sad, cry alone
