Faith could be an important character. She might see Buffy's transformation as an opportunity to prove herself as the better slayer - turned - vampire. Xander would be there too, probably being the one who has the most trouble accepting Buffy as a vampire at first. And there could be new vampire characters created specifically for the fanfiction, like an ancient vampire who has some knowledge about Buffy's transformation and uses it to manipulate her for their own ends.
Definitely Spike. He has his own complex relationship with Buffy. In the fanfiction, he could be a mentor of sorts to Buffy, teaching her how to be a 'better' vampire, or he could see her as a rival in the vampire world. Giles would also be around. He'd be the voice of reason, trying to figure out what caused Buffy's transformation and looking for ways to reverse it while still guiding the Scooby Gang.
Well, in some 'Buffy turns into a vampire' fanfiction, there could be a plot where Buffy has to deal with the rejection of her friends at first.

Definitely Buffy. She's the one who the whole story revolves around. Her courage and determination make her a fan favorite. Angel is another popular character.

Well, aside from Tsukune, Mizore could be a great addition. She's a snow woman and her cold nature could contrast with Tsukune's new vampire - like heat. Yukari, a young witch, might also be in it.
