Andy saves Hyōbu from drowning and the two are rescued by B.A.B.E.L.. Fujiko and Sakaki take Hyōbu to the Tsubomi Estate to treat him, while Oboro has the transmitter chip from the US extracted from Andy's body and destroyed with The Children's help. By Kaoru's request, Shiho restrains Oboru and learns Hyōbu's location from her. Andy convinces the girls to take him with them, and upon arriving at the mansion, Hyōbu asks him about the man who contacted them aboard the Catastrophe, confirming his suspicions that said man is none other than Eiji Saotome himself who somehow is still alive. Meanwhile Sakaki reveals to the girls that Hyōbu is dying and to save his life, Kaoru offers herself for a blood transfusion. Now in possession of both Yūgiri and Ihachigo, Eiji plans to use both to avert the Esper Revolution led by Kaoru and Hyōbu set to occur in the near future. Some time later, despite still not fully recovered, Hyōbu leaves by himself despite Kaoru's pleas and accepts Andy's offer to accompany him. The two then depart to confront Eiji and rescue Yūgiri.
