Lily, Luka, Miku, Meiko, and other Vocaloids

The story is about a girl named Gwendolyn who moves in with her Aunt Casey. The reason is because her single mother, Clara, is having trouble with money so she sends her to live with her older sister, Casey. On Gwendolyn's first dag of school, she's already being bullied door a populair group known as 'The dark royals'. One day, on a weekend, she goes out into a near-by forest and spot a girl and boy, who are the leaders of the Dark royals at the school, doing this odd ritual. They find out that Gwendolyn is around and they target her. [I might change it up a bit later on]
