I'm not entirely sure as there could be many different themes in a Kocho Visual Novel. It might be about the adventures of a character named Kocho, or it could revolve around a fictional world with its own set of rules and stories.
Perhaps it has unique art styles. Visual novels often have distinct visuals, so Kocho Visual Novel might stand out with its own kind of character designs or background scenery.
A common theme is the clash of different power systems. For example, when Shinobu crosses over into a world like 'Fullmetal Alchemist', her demon slaying powers contrast with the alchemy in that world.
One popular 'shinobu kocho crossover fanfiction' is the one where she crosses over with the world of 'Harry Potter'. In this fic, Shinobu's skills as a demon slayer are put to the test in the magical world. She might have to face new types of 'demons' in the form of dark wizards.
In a more light - hearted scenario, Emily could be a mischievous pet, like a cat or a dog that has run away, and the 'catching Emily' part is all about the family trying to bring their beloved pet back home.
In the 'Emily Rose Story', Emily Rose is a girl who has to endure the horror of being possessed. She is the one that everyone in the story is either trying to help or figure out what's wrong with. Her experiences are what drive the whole story forward.
Miss Emily Grierson herself can be seen as a symbol of the dying Old South. Her decaying mansion represents the decay of the old social order. The rose in the title can be a symbol of love or pity for her. She was once a lady of high standing but as time passed, she was left behind, just like the Old South was being replaced by the new era. And her actions, which seem so out of place in the new society, are like the last gasps of the old traditions.
I don't have enough information to determine exactly who Emily Hanford is in this context. She could be a journalist, an author, or someone involved in the media industry.
A simple fanfic could be that Emily is pregnant and she and Richard take a trip to a quiet countryside place to relax and enjoy the early days of her pregnancy away from the hustle and bustle of their normal life.
Miss Emily in 'A Rose for Emily' is a complex character. She is a symbol of the old South's traditions and decline. She was raised in a certain social environment which made her have a sense of superiority at first. However, as time passed and the South changed, she became a bit of an outcast. Her relationship with Homer Barron was also quite strange. It seemed she was desperate to hold on to something, whether it was love or just a way to defy the changing world around her.
