The Netflix series "Glass Heart," a supreme "coming-of-age music love story" with overwhelming passion, will be distributed worldwide from July 31, 2025. The band "TENBLANK," which appears in the film, will make its debut in the real world.

TENBLANK is Naoki Fujitani, a solitary musical genius played by Takeru Sato. Saijo Akane, a college student drumming prodigy, played by Miyazaki Yu. The hard-working, charismatic guitarist Hisashi Takaoka, played by Keita Machida. And a rock band consisting of four members: a solitary pianist, Kazushi Sakamoto, played by Jun Shizon, who is an ultra-music fanatic.

TENBLANK's music, which will be performed in the drama, will be released in the real world to coincide with the drama distribution! The distribution will take place on July 31, the day of the drama distribution, and the CD will be released the following day, August 1.

The memorable debut album contains 10 songs, including "Melody and Crystals" with lyrics by Yojiro Noda of RADWIMPS and music by Masahiro Tobinai, with a detailed track listing to be announced at a later date. In addition to this song, Noda also wrote several other songs for TENBLANK in the play. Noda, who is a close friend of Sato, who also serves as co-executive producer of the film, said of the tag team, "Ken was so straightforward and serious, that I was taken in by his attraction and did my best, too.The music that Noda has created will be released in the near future.

The physical product will be released in two forms: a standard edition and a limited first edition. The limited first edition will include a Blu-ray with behind-the-scenes footage of the making of the drama.

And today, May 22, a 30-second version of "Melody and Crystals (Demo)," from the album, is available on TikTok and Instagram!
