TENBLANK

TENBLANK is a fictional rock band featured in the Netflix series Glass Heart, a high-energy coming-of-age music love story released worldwide on July 31, 2025, that also debuts as a real-life music project. The band consists of four characters portrayed by well-known Japanese actors: Takeru Satoh as Naoki Fujitani, a solitary genius musician; Yu Miyazaki as Akane Saijō, a prodigious university student drummer; Keita Machida as Takao Naoshi, a hardworking and charismatic guitarist; and Jun Shison as Kazushi Sakamoto, a lonely pianist with an obsessive love for music. Within the drama’s storyline, TENBLANK emerges as a compelling ensemble whose diverse personalities and musical strengths intertwine to create an intense and emotionally charged sound.  Capitalizing on the show’s global release, the band steps beyond the screen to perform and release music in the real world, blurring the line between fiction and reality. Their debut coincides with the series premiere, giving fans an immersive experience that extends beyond the narrative. Highlighted in both the show and their real-world promotion is the song "Glass Heart", which serves as a thematic centerpiece, embodying the band’s emotional depth and musical drive. This dual launch positions TENBLANK as both a dramatic and musical phenomenon.
