The Archaeological Research Laboratory of Jonan University excavated a bronze statue preserved in a glass box from an ancient ruin. Yoshii asked Gaki Doi to help investigate the bronze statue because he wanted to interpret the inscription. Gaki Doi and Musashi brought the items back to the base and found that the bronze statue could absorb pressure. Ayano was working alone at the base and suddenly found that the bronze statue appeared in front of her. After seeing the inscription interpreted by Yoshii, Gaki Doi speculated that the bronze statue might be the bronze demon Geshut.
