Shosaku is first seen "shaking down" Gengo Kotaka with his colleague Machiko Shima for a tape recording that Kotaka has. They get no information from him, because when Shosaku holds his foil-wrapped corn cob against his back, believes it to be a gun, and faints. Shosaku and Machiko bring him back to their base of operations (which may just be Shosaku's home) and they explain their situation. Machiko's brother worked for World Children's Land and went missing. When she read his journal, he had written that the park officials were up to something diabolical. They stole the tape recording because they thought it might contain evidence of their diabolical activities. It is soon decided to do a background check on the park officials, and Shosaku and Kotaka are sent to park overseers home town, where it is revealed that he has been dead for a year. The time then comes to rescue Takashi Shima. Shosaku remains on the ground, while Kotaka and Tomoko Tomoe scale the tower to find him. When the signal is given, Shosaku and Machiko launch a zip-line up to the tenth story window and the three get down safley.
