Biscuit Krueger

Summary
Biscuit Krueger or "Bisky" is a Double Star Treasure Hunter and one of the players who cleared Greed Island. In direct contrast to her child-like appearance, she is 57 years old, using Nen to make herself appear younger. She often uses her resemblance to a young girl to deceive people about her true abilities and nature, although her main reason for disguising her appearance is because of her dislike toward her true form where she appears large and muscular. Biscuit was Wing's teacher mentioned in the Heavens Arena arc and also helped train Gon and Killua.
