Rin Kido

Rin is a girl with bright red hair and eyes. Her hair is tied back into a sort of pony-tail bun. She has fair skin, with a small birthmark under the right side of her mouth.

She appears briefly in Mekakucity Actors, wearing an outfit consisting of a white button-up shirt tucked into a knee-length, dark green skirt. She wore red tights under her skirt and an unbuttoned black cardigan over her shirt. The cardigan had a large collar that was buttoned together, with two diagonal red stars on the right side, near her chest area.

Having grown up in the Kido manor, Rin appears to be a highly intelligent and iron-willed character. Rarely losing her composure, she comes off as a confident, albeit somewhat cold young woman. Tsubomi was very intimidated by Rin’s aloof nature but described Rin as elegant.

Rin cares deeply for her younger sister, and shows a much more kind and understanding nature around her. Rin does not differentiate the family ties to Tsubomi over them being half-sisters. Rin shows a nurturing side as she comforts Tsubomi and assures she loves her to the point of sacrificing her own life when they were locked in the basement by their father.

Although Rin cared for proper etiquette, she didn't allow Tsubomi to use keigo when talking to her since they were sisters, and Rin didn’t want Tsubomi to be formal around her. After Tsubomi broke down from the pressure of living in the Kido manor, they made a promise to come to each other whenever they were feeling down.

Contrary to her initial impression, she is shown to have a playful side as well. When she noticed Tsubomi's dislike of scary stories, she teased her by telling her a horror story of the manor they lived in, much to Tsubomi's dismay.
