Rosalyn is a certified hero. In Ari's adventure, she is the second person Ari meets. He first meets her in a bridge, when he is attacked by ghosts. She uses a rapier as a weapon, and she is quite on it. Years ago, before Ari contained Lord Stanley Hihat Trinidad XIV, or Stan for short, Rosalyn carried him in her own shadow. When he leaves Rosalyn, Stan leaves her shadow pink. Thanks to that, everyone makes fun of her, she is even known as a comic-relief "pink" hero.
