Tamon’s B-Side (2026) — Release Date, Full Breakdown, Story, Cast & Why This Romance Anime Is About to Explode Online

Tamon’s B-Side isn’t just another rom-com anime — it’s shaping up to be the next big global fandom obsession. With its early Crunchyroll rollout in December 2025 and full TV premiere in January 2026, this adaptation is already trending across anime socials, idol fan communities, and shōjo readers who have been waiting YEARS for this moment.

If you love My Dress-Up Darling, Kimi ni Todoke, or A Sign of Affection, buckle up — because Tamon’s B-Side is the next massive comfort anime everyone will be talking about.

⭐ The Plot: A Fangirl’s Dream… with a Chaotic Twist

Utage Kinoshita is your average hardworking high school girl — except for the fact that she's utterly devoted to the mega-popular idol Tamon Fukuhara, center of the boy band F/ACE. Posters, merch, playlists, emotional breakdowns… she’s all in.

But life flips upside down when her part-time housekeeper job sends her to his home.

And here’s the twist that makes this entire story explode with charm:

Tamon the idol = bold, sexy, charismatic, stage-dominating superstarTamon at home = gloomy, insecure, socially anxious wreck

He’s basically two different people — and Utage becomes the only one who knows his real, painfully adorable, embarrassingly introverted side.

As the two grow closer, Utage finds herself protecting Tamon’s fragile self-esteem, managing his mood swings, fixing his emotional messes, and accidentally falling for the real version of him — the boy behind the stardom.

This isn’t just romance.

Its identity.

It’s healing.

It’s the fantasy of “what if your idol wasn’t perfect — and still chose you anyway?”
