Yukiko Shizuma

Yukiko Shizuma is a second year Kagayaki Girls' Academy student and the composer of the idol group Interstellar. She is part of the subunit Do.S.

Personality
Yukiko is a polite, thoughtful and kind girl. She is very selfless, and cares about everyone else much more than herself, putting even strangers first. She is loyal to her friends and those she loves. Yukiko is a dedicated people pleaser, and so will do literally almost anything that is asked of her, to the best of her ability.

However, this means that often she doesn't care for herself until it's too late, and ends up sacrificing too much or overworking herself to the point where she collapses. She suffers from low self-worth due to having experienced bullying in junior high school about being "weak", but she often hides her feelings of despair under a warm smile, which leaves others oblivious.

Despite this, Yukiko is book smart and musically talented, obtaining good grades in school. She also enjoys and takes part in athletics. Due to her gentle and modest nature, she becomes flustered and doesn't know how to respond when people compliment her for these abilities. Although she appears shy normally, when she is in her stage persona she has more confidence and charm.

Yukiko starts to have a fear of invasive fans once Interstellar gains popularity, as she finds them creepy, and is worried that her secrets will be revealed to the public and ruin Interstellar's group career.

Background
Yukiko was born to parents who met during their time performing musical theatre. She has lived in Tokyo her whole life. Brought up by two theatre personalities, at first Yukiko seems a stark contrast to the rest of her family. However, she emerges from her shell when she is performing.

She can play violin, which she has been learning since she was young.

Story
In the story, Yukiko is roped into learning idol dances by her best childhood friend Tsukina. From this, the idol group Interstellar develops.
