I'm not sure specifically, but it could be a prince or princess as main characters. They are often central in stories set in kingdoms.
Perhaps there is a brave knight as one of the main characters. He could be on a quest to protect the kingdom from an external threat like an invading army or a dark sorcerer. There might also be a wise old wizard who guides the other characters with his magic and knowledge. Another possibility is a peasant girl with a special gift or power that she discovers throughout the story and uses to change the fate of the kingdom.
Since it's a visual novel, the main characters could be diverse. There might be a group of friends who find themselves in the middle of a big adventure in the charming kingdom. One of them could be a talented artist who uses his skills to document the strange and wonderful things they encounter. Another could be a merchant's son who has a knack for getting into and out of trouble. And there could be a mysterious figure who seems to know more about the kingdom's secrets than anyone else, and their identity is slowly revealed as the story progresses.
