Takao Ichihata is an avid radio wave amateur, but the centimeter wave transceiver device he assembled has a noise problem. Dr. Kono thought it might be caused by rats making nests and suggested reassembly. Takao accidentally heard a strange human voice during the experiment, and also found that the voice was similar to that of Miki's sister Nazuko. They decided to use a machine to record Najinko's brain waves, but encountered many accidents during the experiment. Takao also received a visit from Soul No. 10, Who wanted to borrow his body, causing Takao's soul to separate from his body. Since then, Takao's soul has experienced a wonderful journey abroad. Can he find his body again? What is the intention of Soul No. 10?
