The Netflix series "Glass Heart" is now available worldwide.
TENBLANK, the band featured in the drama of this overwhelmingly passionate coming-of-age music love story, released their debut album "Glass Heart" at the same time as the drama distribution.
TENBLANK is a rock band formed by four members: Naoki Fujitani, a lone musical genius played by Takeru Sato; Akane Saijo, a university student drummer played by Yu Miyazaki; Hisashi Takaoka, a hard-working charismatic guitarist played by Keita Machida; and Kazushi Sakamoto, a music maniac pianist played by Jun Shizon.

The music video for the song "Eien eien eiyo", which is included in their debut album "Glass Heart" and written by Yojiro Noda (RADWIMPS), is now available.
The cast of MUSIC includes MIYEON, a member of the five-member girl group i-dle, and Torataro Daigo, a young and talented actor who is gaining attention.

The film, which had been attracting a lot of attention before its release as a teaser was suddenly posted on Takeru Sato's SNS and part of the making of the film was shown on a live YouTube broadcast, will finally premiere on August 21 at 9:00 p.m. on Takeru Sato's YouTube channel.
The music video is a story of a man and a woman played by MIYEON and Torataro Daigo.
Each scene is worth watching, whether it is a scene of reminiscing about past memories, a scene of wandering around losing the meaning of life, or a scene of goddess-like beauty.
Various MIYEONs never seen before are impressively depicted throughout the work.

Furthermore, this music video is the first one directed by Takeru Sato himself.
Takeru Sato has been involved in all aspects of the music video from planning, casting, filming, and editing, and a making-of video will be released in the near future that shows him working on the music video through trial and error in his role as director.

TENBLANK's debut album, "Glass Heart," which was released for distribution on July 31 and as a CD on August 1, has been a breakout hit, reaching No. 1 on Apple Music and No. 4 on the Oricon weekly chart.
Eien eien" has an important meaning in the drama "Glass Heart," and Takeru Sato himself directed the music video, which is filled with his thoughts and feelings.
