Tochiro's Mother  

Mrs. Oyama is a resident of Grape Valley on Titan's moon, Saturn. She meets Tetsuro Hoshino when he arrives and provides him with directions for finding Maeter, her son's kidnapper. Additionally, she gives him a Cosmo Gun, hat, and cloak as protection during his rescue mission. After successfully rescuing Maeter, Mrs. Oyama allows Tetsuro to keep the gun and tells him that if he ever encounters her son during his travels, to convey her message of wanting to see him again. Unfortunately, Tochiro does not survive long enough for any further journeys.
