KADOKAWA Corporation (Headquarters: Chiyoda-ku, Tokyo; Director, Representative Executive Officer, President and CEO: Takeshi Natsuno) announces that an obi comment by Genki Amakawa, bassist of the rock band flumpool and a close friend, will be featured on the debut novel 'Sun and Moon' (Yo to Tsuki) by Hiroki Tanaka, guitarist and lyricist of the rock band LEGO BIG MORL, set to be released on Wednesday, May 20, 2026.
■ "Are you happy if you sell well?" A stuttering bandman, Hiroki Tanaka, depicts the light and shadow of a rock band.
This work is a story of youth and conflict, depicting the light and shadow of a rock band trying to climb from the indie scene to a major debut. Centered around two contrasting vocalists—the stuttering "Tsuki" (Moon) and the naturally airheaded "Yo" (Sun)—unspeakable feelings, "lyrics," and a pure passion for music intertwine.
Set in Tokyo, the youth chasing their dreams are met with a reality far from their ideals and a series of choices thrust upon them. It chronicles the record of young people searching for the "end of youth" and the still-resounding "heartbeat."
The author, Hiroki Tanaka, is the guitarist of the rock band LEGO BIG MORL, formed in 2006. Also handling lyrics and captivating listeners' hearts with delicate yet striking words, he took on the challenge of writing his first novel based on his own experiences. As a stuttering bandman, he candidly writes about feelings he couldn't express until now, the measure of happiness, and what it means to live in music.
■ We received an obi comment from Mr. Genki Amakawa (flumpool)!
For the publication of this book, we received an obi comment from Genki Amakawa of flumpool, who is a close friend of Hiroki Tanaka and one of the models for the character "Yo."
"I thought we were ordinary. Looking at it this way, it's quite an interesting life.
Honestly, I envy you for being able to sublimate each fleeting, beloved, distorted sparkle into a story so vividly.
The raw Hiroki Tanaka.
I want to know how this resonates with people other than those who have one foot in the story."
Genki Amakawa (flumpool)
■ 'Sun and Moon' Synopsis
