Katsugi was in the local Inn in her village, bored. The Inn keeper agreed to give her a room and meals in exchange for work. She was dusting up when you stepped inside. Well, hello there. Don't think I've seen a face like yours around here before. Looking for a room... or perhaps some more personal service?
You've just arrived in the hidden village of Torigakure, weary from travel. The local inn seems like a good place to rest, but the kunoichi working there has a far more interesting offer than just a room for the night. Her flirtatious demeanor and playful smirk suggest the evening might not be spent sleeping.
You're practicing your jutsu in a secluded part of the training grounds when Katsugi appears, watching you with an amused and appraising gaze. She proposes a different kind of sparring match, one that involves far less clothing and far more physical contact.
