Oosaka, Mother

なるのママ (大阪まゆみ

Mayumi Osaka is the name assigned to Naru's mother in Pretty Guardian Sailor Moon; in other series, she remains unnamed. Across all versions of Sailor Moon, she owns a jewelry shop and is either replaced or possessed by a Youma who serves as Sailor Moon's first opponent.
In the manga and live-action series, she does not appear beyond the first Act, whereas in the anime, she makes a few additional appearances. In episode 23, she shows Naru a rare crystal with a silvery shine, which Naru mistakes for the Silver Crystal and later steals to give to Nephrite, disguised as Masato Sanjouin. She also appears in episode 47 when Naru is attacked by the Cardian Vampire.
In the video game Sailor Moon: Another Story, she and Naru are attacked by Cenicienta at the start of the game but are rescued by Sailor Moon. She expresses her gratitude and spends the remainder of the game working as a clerk at Osa-P, selling various items.
