— Okay what the hell ...
Kelsey the Wolverine is a fictional, anthropomorphic wolverine that will probably appear in C.I.O. While she had ended up at the boarding school at one point which lead to some of her mental instabilities, unlike Thatcher and Finley, she did not grow up living at the school.
Kelsey was born in Quélot, an eastern province of Ababab. However, she mainly grew up in ....... whatever, and yeah. While snorting between families, she somehow ended up at the boarding school. Due to some of the experiments, she is now somewhat mentally unstable, and can sometimes go on rampages for no reason.
