THE iDOLM@STER POPLINKS Profile Quote
"…I'm Kazuki Tsukumo. A former novelist. I continue to be an idol because I want to face myself from the secrets I've been holding…"
Character Description
Kazuki is a quiet and calm former novelist. He is quite observant and often takes notes in order to help him see things more clearly. Kazuki prefers to be alone, but also enjoys the company of his unit, F-LAGS. Because of his imagination, he sometimes makes up stories about others. He is very quick at reading, as shown when he read many thick books in one week despite all of his work, and is also good at memorizing books. After being inspired by Ryo Akizuki, who started performing as a male idol, Kazuki became an idol in order to change himself and to show the world his true self.
Kazuki has social anxiety and is often seen standing off to the side at parties and going out of his way to avoid crowds. However, Kazuki will go somewhere if Ryo and Daigo are going too. Ryo and Daigo can also tell when Kazuki is feeling uncomfortable and will act silly to try and make him feel better, like in the Halloween Live 2015 event where they surprise him with big, costume hats to make him smile.
Kazuki has medium-length orange hair that covers his left eye. His most common outfit is a green-gray shirt and green-yellow scarf, and his F-LAGS outfit consists of a white peaked cap and unbuttoned admiral jacket over a striped shirt.

Trivia and Fan Culture
Trivia
- Kazuki is the first of the SideM characters to be recast, due to his original seiyuu (Tatsuya Tokutake)'s full retirement from character work in late 2019.
- This also makes him the second character in the entire iDOLM@STER franchise after Yukiho Hagiwara to have two different seiyuu (not counting Xenoglossia, which featured entirely different voice actresses).
Fan Culture
- Kazuki is part of the unofficial unit 19歳組 (lit. 19-year-old group, often shortened to 19gumi by English-speaking fans), alongside Kuro Kiyosumi and Sora Kitamura. The three share similar themes of being true to themselves due to their age and having a joint calm and mature aura. They featured in an event together in Write for someone ~A Reminiscent Sky~, fittingly set in 19th century London.
