While in town, Erin accidentally breaks the harp Ia-lu the Seh-zan gave to her when she was 10. She goes to a harp shop to have it fixed, where the carpenter Yantoku was Ia-lu's friend. Ia-lu coincidentally happened to be in the shop when Erin came and immediately recognized the green-eyed girl he met 4 years ago. But after she left, Ia-lu was ordered by his troop to kill his teacher, Hagaru, due to treason.
