Biscuit Krueger
Bisky, ビスケット＝クルーガー
Biscuit is a 57-year-old woman who resembles a 12-year-old girl. She possesses expertise in Nen training and continues to impart this knowledge on Gon and Killua as per Wing's instructions during the Celestial Tower arc. As a treasure hunter, Biscuit takes pleasure in collecting rare jewels (and even gives them names) while earning money. Her personality is devious; she uses her cute appearance and demeanor to manipulate others for information gathering, obtaining what she desires, or even engaging in combat by feigning innocence and helplessness, causing people to lower their guard around her. However, as a Nen teacher, Biscuit adopts a strict and serious approach towards her students.
Though in the beginning she was out to destroy Gon and Killuas friendship, at the end of Greed Island she acknowledges (albeit, in her head) that shes close to developing parental feelings toward the two of them.
