The vibrant animation style from J.C. Staff is anticipated to bring Yuki Shiwasu’s expressive artwork to life.
January 1, 2026, Marks Streaming Premiere
The most significant announcement alongside the trailer is the definitive streaming debut date of January 1, 2026. This allows fans to dive into the world of “Tamon’s B-Side” right at the start of the new year. For television broadcast, the anime is scheduled to premiere on January 4, 2026, on channels like Tokyo MX and BS11. This dual release strategy ensures broad accessibility for the highly anticipated shōjo adaptation.
Diving into the World of Tamon’s B-Side
The story of Tamon’s B-Side revolves around high schooler Utage Kinoshita, an ardent fan of Tamon Fukuhara, a member of the popular boy band F/ACE. Utage’s fangirl life, funded by her part-time housekeeping job, takes an unexpected turn when she finds herself working at Tamon’s house. Here, she discovers that her idol’s charismatic “Hottiehara” stage persona is a stark contrast to his gloomy and insecure real-life self, affectionately dubbed “Gloomyhara.”
Driven by her unwavering devotion, Utage takes it upon herself to support Tamon, refusing to let his insecurities hinder his career. The narrative explores themes of fandom, self-doubt, and the often-humorous challenges of supporting someone from both a fan’s and a personal perspective.
The Idol Group F/ACE
Central to the plot is the in-story idol group F/ACE, whose music and performances are a driving force. The group has already released a music video for their debut song, “F/ace Off,” which was made available on streaming services. The insert song “Supernova” is also performed by F/ACE members.
