Invisible

Sarada receives a bath serum that promotes clear skin. But when she uses it, it turns her skin clear! Thinking she can pull a few pranks of her own with her new invisibility power, she stalks the academy looking for ways to cause problems for Boruto. But in time, people start forgetting her name! Will anyone remember who she is before she's erased from existence?
