Usagi Yojimbo #52 (2001)

As a thief, all that matters is skill and quarry, and few know this as much as the master thief, Kitsune. While on the road with her new traveling partner, Gen, the lady of pocket picking finds her own pockets picked, which makes her nostalgic. And so begins the story of Kitsune's youth. The daughter of a prosperous merchant fallen on bad times, Kitsune grew up homeless on the street, stealing to survive. Though she is certainly an expert at thievery now, she wasn't always. This is the story of girl learning to use her wits to survive under the tutelage of a kindly street performer. But good times don't stay that way; all it takes is robbing the wrong person before the ground falls away.
