One year prior to the Earth ship Yamato's first flight, she comes to Earth with designs for a wave motion engine to be constructed inside Yamato. While there, she and a human companion with an uncanny resemblance to her, Yuki Mori, are caught in a possible terrorist bombing that destroys their vehicle and severely injures Yurisha. Before lapsing into a coma, she gives Mori a holographic message capsule from Queen Starsha, and forms a psychic connection with her.
