Unveiling Idol Osare Note: A Journey of Friendship and Growth
One of the inaugural titles, Idol Osare Note ① Unfinished, Us., offers readers a unique opportunity to immerse themselves in the world of a fictional idol group, cheering them on as if they were real. This story resonates deeply with the growing phenomenon of “oshi-katsu” (推し活) in Japan, where 50-60% of elementary school students are said to have an “oshi”—a beloved idol, character, or person they passionately support. “Oshi-katsu” is a vibrant form of self-expression, a channel for emotional energy that, in turn, fuels the growth of those being supported.
This novel delves into the friendships and personal development of girls striving in the idol world. It’s perfect for those fascinated by entertainment, eager to find characters to cheer for, or who appreciate stories of friendship, even through its challenges. Readers who are drawn to individuals pursuing their dreams with dedication, or those who enjoy projecting themselves into a character’s journey of growth, will find this book particularly appealing.
A Message from Author Yuzuki Hachiya
Author Yuzuki Hachiya shared a heartfelt message regarding the publication:
“The dazzling world of idols—it’s filled with immense effort, internal conflicts, and unwavering resolve. And the adults supporting these idols also carry their own unique aspirations. The air around entertainment constantly carries the scent of youth, bright, bittersweet, and at times, poignant… Perhaps that’s why people are drawn to idols, compelled to support them like a sweet fragrance.
In this work, I poured specific feelings into each of the four idols. My hope is to deliver crucial messages through this story, empowering girls living in today’s world to face forward with dignity. I aspire for this work to grow alongside the four idols, gently encouraging our readers forward.”

The Story Unfolds: Dreams, Struggles, and Bonds
The narrative centers on second-year middle school student Asuka Tamamura, who successfully auditions for “2% Production.” She forms a group with fellow qualifiers Kureha Mashimo, Sae Ikumi, and Nagomi Oba, embarking on a challenging journey toward their debut. Their path is fraught with obstacles, including “pre-debut evaluations” set by the president, covering everything from dance and social media to greeting events. Each of the four girls also grapples with their own personal struggles, making for a deeply relatable tale of growth, challenges, and the enduring power of friendship.
