Sisters Being Sisters Though coywolves Kitusi and Skylia are biological sisters, Fukiya happens to have different parentage. That does not stop this trio from living like sisters. Fukiya, being the oldest and the bravest, would do anything to protect her two younger non-biological sisters from harm--even if it means putting herself at great risk to do so. The three are mostly inseparable, and any challenge one of them faces is essentially a challenge for all three to take on together.
