Biscuit Krueger (ビスケット=クルーガー, Bisuketto Kurūgā) is a Double Star Treasure Hunter that enlisted in clearing the video game Greed Island following the auction for the game in Yorknew City. She prefers to be called "Bisky", although she jokingly said that if someone insists on using an honorific, they must call her -chama (-chan + -sama).
