Mrs Tanaka (田中, Tanaka-san) is a character from the anime Servant x Service.
Mrs Tanaka is an elderly lady with grey hair done into a low bun. She is very short and her eyes always seem closed, even when talking to other people, giving her a very relaxed appearance. She wears a red kimono, white socks and geta.
Mrs Tanaka always comes to Saya Miyoshi's window to rant about her daughter-in-law for hours on end. She is very proud of her grandson Joji and always sings praises of him.
While she seems pretty relaxed when talking to people, she can be very protective of the people she cares about. This is shown when Tohko speaks harshly of Saya, she fiercely tells Tohko off.
She also seems to be a dominating figure in the Tanaka household as Joji says, whatever she says, it goes.
