A certain Ya is a fox-shaped guardian fairy, and her full-time job is to protect contractors.
A certain Ya is a bad person. She has had no luck since she was born. She often wakes up to see BOSS-level people fighting in front of her, with the simple purpose of robbing her. A certain Ya is also a bad person when walking, and she walks into a dangerous area set by a certain person: A certain Ya finds a contractor to change the bad, and nine out of ten people break the contract voluntarily, directly. As a result, a certain girl fell asleep and went back to sleep. She wanted to ask the last contractor why she didn't break the contract, because she was a fool and didn't know how to break it... What's more, she was obviously as cute as she wanted to be, but she was always ignored... (A certain girl: (Looking at the sky——) When will I not be unlucky——)
