Satou's group never met the ratmen cavalry in the wilderness due to their extended stay in Seiryuu City. And while the ratmen were still decimated by Zen's pursuers, Mize alone manages to escape and bring Mia into Seiryuu City.

With the conclusion of the incident at the Maze of Trazayuya and Satou's departure from Seiryuu City, Satou's group chances upon the route taken by the ratmen cavalry during their flight from Zen's pursuers. As Mia mourned for her former protectors by reciting their names, Satou soon noticed some of the people named were in fact alive and being held as slaves in a nearby town. Having rushed to the town to secure the ratmen's freedom, Satou sets off towards the Ash-mouse tribe's village in order to take the ratmen home.
