Hime and Flandre, driving a truck, trail Riza outside to a dead end, where Hime tells Riza that her actions would be shaming Wildman's death. Riza had not realize until now that she herself was used as a chess piece to make Wildman betray Hime. She later goes to her brother's grave and mourns for his death before she departs.
