They find that the demon twins escaped from their village and were taken under the wing of "God", a mysterious figure who granted them whatever they wanted. However, as punishment for one of the twins, Ginkaku, wanted to run away, he transformed him into a monster and convinced his brother to kill "bad guys" in order to return him to normal. In the end, "God" appears to finish off the two of them, because he considers them "toys" which he free to do whatever he wants to them. Deeply disturbed by the murder of the two innocent boys, Gojyo runs off without the others the next morning.
