I, who lives in the countryside, came to Tokyo to find a job. I decided to stay at a relative's house for the first time in over ten years, while I was looking for a room. And when she reunited with her cousin Hikaru, who became a school girl, she became very cute and even became a small devil. Contrary to her cute face, her mischievous heart awakens and her provocation escalates! Girls in Tokyo are amazing, it feels good, but... scary. The actions of Hikaru, who is a little devil, will steal your energy both physically and mentally.
