The story revolves around Yato, a poor minor deity whose dream is to have his own shrine and be worshipped by the people. In order to get more followers, he tries to spread his name by writing his cellphone number on the wall of restrooms across the city and offering his help for 5 yen. One day, a girl named Iki Hiyori saves him from getting hit by a truck, but she gets hit instead, although she somehow survives the accident without any serious injuries. However, Hiyori's body becomes "abnormal", so she pursues Yato in order to return her body to normal, and that becomes the beginning of their journey together.
