Yato answers a prayer worth five yen to defeat a Snake Phantom, using his Regalia, a divine weapon, named Tomone. However, Tomone terminates her contract with Yato due to his impoverished state. When Hiyori Iki saves Yato from being hit by a bus, she injures herself and briefly has an out-of-body experience. After she is taken to the hospital, Yato introduces himself as a God to her. The next day, Hiyori begins having drowsy spells despite full recovery. Yato encounters a Toad Phantom, but Hiyori helps him escape. Due to the bus incident, Hiyori has become a Half Phantom; her spirit can frequently leave her human body. Hiyori wishes to return to normal, and Yato accepts the wish for five yen.
