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.

πI recommend the following two novels to you: The Princess Marries: The Black-bellied Prince Spoils the Crazy Concubine and The Killer Attacks: Finding a Creditor to Be the Empress. Both novels were romance novels. The male leads were assassins, while the female leads were a princess and a modern assassin. Among them,"The Princess Marries" was an ancient romance novel about western time and space, while "Assassins Attack" was an ancient romance novel about time travel. I hope you like this fairy's recommendation. Muah ~π
I recommend "Quick Wear: A Guide to Whitewashing" to you. This is a sci-fi space-time travel novel. After the death of the protagonist, Yan Xi, he embarked on the path of training all kinds of evil and arrogant CEOs. He also had special training skills that specialized in treating all kinds of difficult and miscellaneous diseases of CEOs. The goal was to train all the perverted CEOs who had weird habits and scumbags who had scumbags and lovers into good CEOs who loved their jobs, were dedicated, and cared for their families. Although it was supposed to be a proper training, if you like to rot, it's also very cute ~ I hope you like my recommendation, muah ~π
Killing Without Ring1 is very suitable for you. The main character, Chen Yan, was very reclusive, but very smart. After entering the online game, he created a personal team mode and used unique calculation methods to deal with unknown opponents, causing a huge wave in the online game world. I hope you like this fairy's recommendation. Muah ~π
I recommend "The Viceroy of France." Although it is an ancient female romance novel, the plot is still very attractive. It describes a heart-wrenching love story in the historical background. I hope you like this fairy's recommendation. Muah ~π
