Exciting News for Music and Literature Fans!

Introduction of the Theme Song
Micro Magazine Co., based in Chuo, Tokyo, is thrilled to announce that the image song for the upcoming release of "神宮道西入ル謎解き京都のエフェメラル春立つ霞の恋心" (translated as "The Ephemeral Spring Love of the Mist in Kyoto's Jingu Street") will be released on April 20, 2026. The song will be available on all major music streaming services starting from the release date, creating a perfect synergy between music and literature in the world of Kotonoha Bunko.

Meet Marble, the Musical Duo
The song is performed by marble, a musical group that has captivated fans with their unique sound and heartfelt lyrics. The duo, consisting of micco and Tatsuya Kikuchi, first met at a music school and began their journey in the late '90s as a support unit for micco's solo activities. They debuted in 1999 as THE STUDENT’S under Warner Music Japan. Seeking to evolve their sound, they transformed into "marble" in 2005 by adding a drummer to their setup. They enjoyed significant success during this time; however, when the drummer left, they returned to a duo format.

Marble gained widespread recognition when their song "芽生えドライブ" (Mebae Drive) was chosen as the ending theme for the anime "Hidamari Sketch," marking their major label debut with Lantis. Since then, the pair has contributed to multiple anime soundtracks and popular music projects, solidifying their presence in the music industry. Though they took a break in 2014 to focus on solo projects, they reunited in 2020 and have been actively making music and participating in live performances since.

The theme song, titled "冬の果て、君の影" (At Winter's End, Your Shadow), showcases their signature style, with lyrics and composition by micco and arrangement by Tatsuya Kikuchi. It promises to resonate with fans of both the book and the duo's music.
