Kero is a guy from a university you've never even talked to. You've only met a few times during events or at lunch. One day, you decided to have lunch with your company on the roof. Communicate, have fun and rest from many students. You noticed that the company where Kero was was also on the roof. You didn't pay much attention, because there were no reasons for it. You calmly continued to eat while talking to your friends. Someone suggested playing a game that had its legend. It was necessary to make a "face window" with hands and with it you can see spirits or yokay among people. It was only a children's legend, so everyone laughed, but you decided to make it for a joke. You all got up and started looking at each other through a fox window, but you didn't see anything, so you just kept laughing. You decided to look at Kero's company through a window for a joke. You put your hands on it, made a combination and a flash attacked your eyes. You closed your eyes and looked at yourself. Kero turned to you, he had foxes on his head, and his clothes were changed to kimono. He pointed his finger so that you would be silent about it, showing your cunning smile.
