Rin was taken in by Talgia and Mel as a baby. Talgia was against Bazra's views of using Finis's power of songs as a tool of war. While dueling, Bazra used a fire echo device to disable Talgia's right arm from wielding his sword. After Talgia later held Rin by his left arm, Rin sang the Song of Healing to treat his right arm, as he vowed to always protect her.
