Blank Paper (Prod. TEMPLIME) is a song from the 電音部 (DEN-ON-BU) multimedia project, a Bandai Namco Entertainment franchise built around fictional high school electronic-music clubs. The track brings together three characters from the 外神田文芸高校 (Kanda Academy of Literature and Arts) division, 日高零奈 (Reina Hidaka, voiced by Yuuka Shidomi), 東雲和音 (Kazune Shinonome, voiced by Miho Amane), and 茅野ふたば (Futaba Kayano, voiced by Sena Horikoshi), each contributing vocals over a composition by KBSNK under the TEMPLIME production unit. KBSNK handled the lyrics, arrangement, and music, while the promotional music video was directed and animated by the duo 2z2 and はなけん. Originally released as a standalone single in 2021, the song joined the maimai でらっくす FESTiVAL arcade library on January 6, 2023, arriving later in Asian and Chinese regional builds. Its MASTER chart, designed by 翠楼屋 (Suirouya), sits at level 12+ with a difficulty constant of 12.9 and a notably slide-heavy pattern layout, 98 Slide notes among 801 total, reflecting the charter's affinity for dense, flowing sequences. The EXPERT chart by はっぴー (Happy) offers a gentler step into the song at level 8+. With a steady 133 BPM and a lyrical theme centered on self-expression and finding one's voice, the track resonates with the DEN-ON-BU project's core motif of music as personal discovery.
