Chessy Prout, an American teenager who spent most of her childhood in Japan, initially felt a sense of powerlessness as the #MeToo movement against sexual harassment and assault gained steam last year.

About four years before the movement evolved into a global force, Prout, now 19, was sexually assaulted by one of the most popular senior students at an elite boarding school in New Hampshire.

Fast forward to late 2017, and she began to see she was not alone in her experience. But she also felt overwhelmed by the scale of sexual violence.
