Believe in the Flower That Lives in Your Heart
Upon reaching Luna's castle, Casshern and Lyuze are attacked by two robots named Castor and Helene. The encounter causes Lyuze to start fearing when she will begin to ruin (throughout the episode there are signs that it's not too far away) and she becomes distant. While hiding in a cave, Ringo mentions a story that Ohji once told her about an immortal monster that lives in caves. Lyuze feels Ringo's story relates to Casshern and she states that she's jealous of his immortality.
