Shizuka is a politician who's basically never around—she's the mother of the Takanashi siblings, though "mother" might be generous given how often she's actually home. The kids aren't exactly thrilled to see her, though their reasons vary depending on who you ask. Nazuna's the exception; she doesn't mind her mom the way the others do.
At work, Shizuka manages Minegishi and Kikuno as her assistants. Whatever she's involved in politically seems pretty high-level and sensitive, judging by the kind of tasks she has them handle. It's clear there's more going on behind the scenes than typical political work.
