Often, there are also human characters who interact with the U - Kiss vampires. These human characters can be love interests, friends, or sometimes even enemies. They add a different dynamic to the story as they are the ones who are not used to the vampire world. They might be curious, scared, or attracted to the vampires, which all play into the plot.
Typically, the main characters are those involved in the contestshipping relationship. It could be characters like May and Drew. They are often the focus as they are the ones with the potential for the romantic connection that leads to the kiss.
In some fanfictions, there might be additional side characters that play important roles. These could be friends or family members of the main couple. They might influence the relationship in different ways, like giving advice or causing misunderstandings.
Love and romance are also common themes. For example, a vampire member of U Kiss falling in love with a human and having to deal with the complications that come with it, like the difference in lifespan and the danger of their vampire instincts.

Rick often plays an important role too, either as Morty's protector or as someone who has to deal with Morty's new vampire state. Sometimes, other characters from the Rick and Morty show like Summer or Jerry might also be involved.
Well, of course, Conker is often the main character. Whether he's the hero fighting against vampires or a vampire himself, he's central to the story.
