The official website for the anime of Yuki Shiwasu's Tamon’s B-Side (Tamon-kun Ima Docchi!?) manga posted a music video and announcements for the anime's tie-in voice drama and January 2026 premiere. The music video is for "F/ace Off," the debut song from the in-story idol group F/ace.
The song will be available on music streaming services starting at midnight (11:00 a.m. EDT).

Viz Media licensed the manga, and it describes the story:
Tamon is an insecure mess in real life, and what's worse, he's threatening to quit! Utage refuses to let anyone stand in Tamon's way—least of all himself. What's a fangirl to do but roll up her sleeves and support her favorite singer with everything she's got?
Shiwasu (Takane & Hana) debuted the manga in Hakusensha's Hana to Yume magazine in October 2021. The series is based on Shiwasu's earlier one-shot manga of the same name.
The manga was nominated for Best Shōjo Manga in Kodansha's 47th annual Manga Awards in 2023. The manga ranked at #9 on the top 20 on its list of manga for female readers in the 2023 edition of Takarajimasha's Kono Manga ga Sugoi! (This Manga Is Amazing!) guidebook.
