I’ll sum up her backstory (am planning on making a story about it once I work on it more)
Basically, she joined a cult who kills people. And because of this, she killed people who threatened or did anything mean to the girl she liked. But the girl had known about this and led her on. The girl (we’ll call her Ash for now, she doesn’t have a name yet), begun purposely making people hate her and Lapis didn’t realize this. And sometimes she would lie about people being mean to her. And one day Ash told Lapis that the leader of the cult had beaten her brother up. Lapis believed her and went to kill the leader, which was when he killed her.
The reason why Rät is her theme song is because the “apple” that she ate was the risk she took. ”I bit the apple because I loved you, and why would you lie?” Which is her saying why would Ash lie about someone being that cruel. The backstory is still in progress and I’ll probably change a lot.
The Ghosting is her before she finds out that Ash lied and remembering before she had joined the cult. I might remove this one but I had a plan for it before but removed it. But I keep it in her theme songs because I might use a renovated version of the idea at some point.
