Esme was once part of an Espeon tribe who lived secluded in the forest from society and other Eeveelutions. As a result, she does not fare well with understanding technology or the modern world. But she definitely knows how to fight, especially with weapons like crossbows, and her trusty katana. In her tribe, the kimono is clothing of purity, and of sacred importance to one's presentation. But she is not a nice individual to outsiders, mistrusting them. She will make them earn her trust instead.
