Osamu Oishi (大石 理, Oishi Osamu), also known as Mama (ママ, Mama) to her patrons, is a minor character in AI: THE SOMNIUM FILES and a character featured in AI: THE SOMNIUM FILES - nirvanA Initiative and the Lemniscate YouTube series.

She is the mama, or hostess, of the "Snack Bar" Marble, located in Golden Yokocho. She appears to be the only staff within the bar. She also has connections to the criminal underworld, as she doubles as an information broker for Kaname Date about these matters.

Personality

Fitting for a hostess of a bar, Mama is friendly, professional and genial to her clientele. She's very playful and enjoys teasing people with suggestive jokes about men, particularly with or about Date, who's more than willing to tease her back. She's strict about making sure under aged people and drivers do not get access to alcohol, and is quick to close the tap when she thinks someone has had too much. She also has the uncanny ability to sense when someone is a virgin.

Mama is eager to help Date and other ABIS members with providing information whenever she can. However, she spends much of the first game being somewhat out of the loop (due to the strange nature of the New Cyclops Killings making conventional intelligence unhelpful), by the events of Nirvana Initiative, Mama has seemingly awoken psychic powers that allow her to commune with spirits, which allow her to be more helpful to Ryuki and Mizuki, regularly giving the two helpful clues for the case. These powers initially appear to be an act, as she often uses them as a set up for further suggestive jokes, eventually they later prove to be surprisingly genuine, and allow her to provide information she shouldn't otherwise know, and even break the forth wall and directly address the player, although she generally does not remember afterward.
