Catherine

An amanto who resembles a cat. At first, she seems to be a diligent worker at Otose's snack shop who is trying to support her family, but soon reveals herself to be a thief. Despite this, Otose hired her again after she was released from prison. She used to work as a thief with three others vaguely resembling Arsène Lupin, Goemon Ishikawa, and Daisuke Jigen. She speaks Japanese with an accent, represented by katakana characters in the place of hiragana; she is the only member of her former crew to speak this way. Source: Wikipedia
