Alice invites Yune to come to an exhibition at the Grand Magasin, but Claude is strongly against it for some reason. As a reprise, Claude takes Yune and Oscar to a picnic in the park. After seeing her upset whilst thinking about home, Claude asks Yune to tell him about her sister, Shione. As Shione was often looked at strangly because of her pale blue eyes, Yune, who was weak at the time, made a prayer that she would only be able to look at her. However, as time went on and Yune became stronger, Shione's grew weak and went blind, which Yune blames herself for to this day. However, Oscar assures her that Yune's words made Shione happy.
