Mizuki Tsujimura

Mizuki Tsujimura (辻村 深月,) is an agent of the Special Ability Department and she is assigned to Ayatsuji Yukito. She is the deuteragonist of the spin-off novel.

Appearance
She has light cyan hair which is parted to the right, part of which she keeps in a ponytail. She wears a white neck scarf patterned with the same cyan hue, a white dress shirt, a gray suit coat which she keeps unbuttoned, and gray slacks. She also wears gray gloves, black heels and a dark gray belt.

Personality
Tsujimura appears as a kind and genuine woman, though slightly gullible as shown when Ayatsuji tricks her in making him coffee.

Tsujimura is also very dedicated to her job and respectful to her seniors. She constantly struggles to get Ayatsuji to follow protocol, harshly reprimanding him when he does as he pleases. Feeling strongly about her duties, she often gets swept up in the moment.

Ability
Tsujimura's ability, Yesterday's Shadow Tag (きのうの影踏み,), allows Tsujimura to create 'baby shadows' and control their strange/curious lives.

Just like Kyōka, her mother transferred her ability to her. Therefore, she does not have complete control over her ability.

Background
She is an agent of the Special Ability Department, under Ango Sakaguchi. She is assigned to watch over Yukito Ayatsuji, an Extremely Dangerous Ability User.

Trivia

 * Tsujimura's mother taught Kyōka's mother how to transfer an ability to a blood relative.
 * The author's inspiration for writing mysteries stems from Yukito Ayatsuji's writing.
