Marina Tendouji

Marina Tendoji is a minor character in the Oshi no Ko manga series. She is part of an advertising agency helping to promote the 15 Year Lie autography film about Ai Hoshino's life, as well as the mother of Sarina Tendoji, Ruby's past life, who seemingly gave up on her terminally ill daughter.

Appearance
Being in her 50s, Marina's age shows through the multiple wrinkles she has on her face. She has curly-brown hair and is of average stature.

Personality
On the surface, Marina appears to be a sociable person who enjoys going out with her co-workers, admitting to having something of a drinking problem. Beneath this, however, she appears to be a rather elitist woman, seemingly being ashamed of her terminally ill daughter to the point of never even visiting her at the hospital and omitting her from family photos. She even had the gal to state that "children should be healthy", even though she completely neglected her own daughter.
