Penguin's rival, represented by a polar bear. A tragic moment in her past has caused her to despise the Nankyoku company, and constantly seeks to overwhelm it, normally by building something bigger than what they have. Later on though, she becomes bankrupt and has to use tattered clothing whilst maintaining her lady-like dignity. She is also referred to as 'Shirokuma' (a literal translation of Whitebear) and is sometimes called 'Kuma-san' by Penguin.
