The troupe runs, but Percival easily catches up to them. He explains he is looking for Ironside, but none of the have heard of it. Katz proposes he comes with them to the nearby village, where he may find some info. On their way, Katz explains they are drop-outs, who failed to become Holy Knights. Percival reveals that Ironside and his grandfather were also Holy Knights, which surprises everyone that Percival is a son of a Holy Knight. Arriving at the village, they see a big wolf, who Percival easily defeats and shocks them by his strength.
