The Beast Player Erin - Season 1 Episode 22

Erin goes to the capital with Tomura and her two followers, Nuk and Mok, to go back to the Yantoku harp shop and change the harp to make a sound resembling an Ohju. They are allowed to borrow the shop for a few days while Yantoku is out. In another part of town, Ia-lu reopens his arrow wound while fighting against two unknown assailants, and stumbles upon Erin and her friends. They bring him into the shop and tend to his wound. After hearing Erin's story, Ia-lu decides to teach Erin how to fix the harp the way she wants to. With Ia-lu's help, Erin is able to make the sound she wanted and help Lilan eat again.
