Marina Tendouji

Marina Tendoji (まりな) 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 biography film about Ai Hoshino's life, as well as the mother of Sarina Tendoji, Ruby's past life, whom she seemingly abandoned.

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 trying to erase her existence. She is also hypocritical, stating that "children should be healthy" despite neglecting said daughter.

Background
Much of Marina's past remains unknown. At some point, she got married and had three children, including Sarina.
