As the elder Jougasaki sister and fellow idol in the Passion category, Mika Jougasaki is a fan of the gal subculture. Like any older sister, she and Rika Jougasaki don't always see eye to eye, and squabble on occasion, but most of the time they get along just fine. Mika really cares for her little sister, and serves as a bit of a role-model for her. Her experience as an older sister also shows itself frequently when it comes to interacting with idols younger than her for the Cinderella Radio segments; she's very good with kids. She uses textual stars, ★, within her in game lines.
Mika puts on an outward show of glamour and sex appeal, but is actually somewhat shy when it comes to expressing herself. Mika’s outfits are all extremely showy and reveal a lot of skin. She actually notes in her Rare+ form that she wouldn't mind showing more skin, but going any further would be inviting a media circus. Her S Rare+ card has her nameplate conveniently preventing an outright shot of her underwear.
In the Cinderella Radio segments, if the idol being interviewed isn't one prone to starting mayhem herself, Mika is usually the one to instigate something. Her CINDERELLA MASTER interview was redone after she actually passes her adlib challenge with flying colors on her first attempt. She insisted on a redo to spice it up a little, which she fails multiple times before getting into a shouting/buzzing match with the staff that causes the broadcast to be temporarily halted.
