Seventeen-year-old Utage Kinoshita lives and breathes for her favorite idol group, F/ACEābut the group's center, Tamon Fukuhara, occupies a special place in her heart. Every waking moment Utage dedicates to the thoughts of the wild and sexy Tamon, even taking on a part-time housecleaning job just to afford her fangirl lifestyle. What was supposed to be an ordinary job turns out to be anything but when Utage realizes she is cleaning the apartment of the very idol she so fervently admires! But adding to the surprise, Tamon is nothing like his on-stage persona; he suffers from severe anxiety and painfully low self-esteem. Keenly aware of the gap between their worlds, Utage cannot bear to see Tamon so depressed and decides to support him the best she can as his housekeeper. As time passes, Utage becomes more and more privy to the aspects of Tamon's life he reveals to nobody else. And the bond that forms between them soon leaves Utage wondering if she has accidentally crossed the sacred line between fan and idol. [Written by MAL Rewrite]

In the midst of a shoujosei golden age itās only right that my anime of the season be a shoujo. I knew right from the jump that Tamonās B Side was special. Over the last year, Iāve fallen deeper and deeper into K/J-pop idol culture and itās probably my biggest hyper fixation after anime at this point, so the concept of a show where an idol stan meets their oshi and they fall in love is right up my alley. It sounds like simple wish fulfilment, but itās actually so much more substantive than that and has some of the best written characters and developmentaround. Iām not going to say itās the most complex story ever, it definitely retains a lot of those shoujo wish fulfilment elements, I mean the very concept of you meeting your idol and them only having eyes for you is so unlikely, but the author makes sure to develop Tamon and Utageās relationship beyond that. The series also examines the pressure young idols are under to maintain appearances and how that can affect their mental and emotional development. Our idols provide so much joy for us, but theyāre never allowed to show how theyāre truly feeling deep down and thatās a shame. F/ACE might be fictional, but I love these boys just as much as any real life idol group because of how well written every single member is. I had so much fun watching this every week thanks to the amazing characters, the well executed comedy and the beautiful production values. I couldnāt be more proud to say a show was my fave of the season. Thereās a lot to love about this show for me. At the center of it all is Utage and Tamonās relationship. They meet by pure coincidence through Utageās job and she ends up working for Tamon. Initially, their interactions are dominated by Utageās adoration for Tamon the idol. This quickly changes as she comes to see more sides of him and learns who he is as an individual, under the idol persona. Itās such a cute developmental path because Utage comes to realize Tamon is an insecure dork under all the boy crush heartthrob facade, but she learns to love him as he is. The sincerity he exudes, his hardworking personality, the way heās so concerned for her, his group mates and other fans and wants to keep everyone happy.. we eventually learn that while heās different from his idol persona, heās just as worthy of being idolized. Thatās a trend that extends to the entirety of F/ACE which Iāll get to a little later on. Going back to Tamon and Utage, their romantic development was a pleasure to experience every week. Itās not really a slow burn because itās obvious how both of them feel about each other, but thereās this gradual progression where Utage goes from being in love with Tamon the idol to Tamon the human being and accepting all of him, flaws and all. I think itās a nice realistic reminder that we donāt really know our idols and it kind of poses the question, āif you knew the real them, would you still love them?ā So many celebrities are totally different in real life, so itās a nice thought experiment. Luckily, our Tamon is arguably even more lovable as he really is than the idol version. Utage herself is amazing too. Sheās not just a self insert character for the audience. Sheās gorgeous, resourceful, intelligent, strong, loyal and fierce. Sheās very much her own person and drives the story forward by helping Tamon and the other F/ACE members. It was so cool watching her week after week because she is THE idol stan that we all strive to be and also THAT girl. She can hold her own against any other female character this season. The other thing to love about this show are the supporting characters! You know a series is good when you have just as many, if not more, fans of the side characters as the main character. Ouri, Natsuki, Keito and Rintaro all have such fervent and passionate fans online that were hyping up all of their big moments this season. This was definitely one of the most fun shows to live watch in a while. I love that all the boys have their own unique B sides that will endear them to different people. Whether itās Ouri coming off like a smug and arrogant asshole, Natsuki being a delinquent, Keito being the biggest cheapskate on the planet or Rintaro being the average otaku, thereās something for everyone here. Whatās more, the reason all of them act the way they do gets explained(except Rintaro in this season) and you just canāt help but go, āyea that makes sense, those circumstances would lead anyone to become like this.ā As I said earlier though, even though the boys are different than their idol fronts, you can see they all posses qualities worthy of being idolized. The way they care for each other, their fans and try their hardest in their own crazy ways is so beautiful. The other thing I like about this story is that it feels like a love letter to oshikatsu and stan culture as a whole. I know stanning gets looked down upon by a lot of people, but I do think it can be a positive outlet for many people of all ages. Itās a way to make friends and feel part of something bigger than yourself. More importantly, thereās absolutely nothing wrong with getting passionate about your fave artists and supporting them. The entertainment industry can be so fickle and brutal, letting your faves know youāll always be there for them and that you appreciate how they keep going despite the obstacles they face is a beautiful thing. Itās obviously exaggerated, but I just felt seen thanks to this series and I can tell this was also a personal story for the author. A lot of heart and genuine soul went into this. The production values in this are so good. The art style and character designs are gorgeous, but the animation has no reason going as hard as it does. I will never get over how good the Utage delinquent transformation scenes or the Utage exploding head scenes were! The voice acting performances are all top notch too, so much talent in this cast! J.C Staff have really been on a roll since COVID and this is just their latest banger. Well done all around. Tamonās B Side was such an amazing experience for me as an idol stan and anime fan. Every single week these episodes went by in the blink of an eye and I enjoyed seeing my girl Utage make Tamon fall even harder for her. Itās the personification of āshe fell first, he fell harderā I laughed at all the jokes, I loved the side characters, the little bit of F/ACE music we got.. I just canāt gush enough about this show. When I was in Japan last month, it was all over the place so Iām really hoping we get a season 2. The manga volumes have been selling like hotcakes, so if thereās ever a show to break that should season 2 curse.. this would be it. Anime of the season no debate. Tamonās B Side gets 10 out of 10.
Click an episode to read its synopsis.
Tamonās B-Side is a story about a female MC who is a fan of the band - F/ACE - more specifically, her idol Tamon. And one day, she ends up getting a job as his housekeeper. Iāll start with the things that I enjoyed about this story first. Tamon, as a character, was incredibly endearing and genuine, and he felt real. He wasnāt perfect; he was messy and problematic, but in ways that felt earnest and genuine. I thoroughly enjoyed him as a character, and enjoyed watching him gain more and more self-confidence in himself and his relationships with others, like his bandmates. For the plot, itwas simple as far as storylines go. There isnāt any conflict the characters have to overcome or any drama that needs to be resolved. Though I tend to enjoy more compelling storytelling, I actually found this plot very enjoyable despite its mild writing. The characters were entertaining enough to keep my attention from episode to episode, and overall, the plotās wholesomeness was very sweet. The music was actually pretty nice too, and I enjoyed all the band membersā charisma and their dynamics with one another. Now, for what I truly struggled with - Kinoshita, the protagonist. While she absolutely had promising things about her character, I found the way she interacted with Tamon honestly bothersome. She continuously calls him a āgodā and an āidol,ā and never progresses to treating him as just Tamon the person. She even separates his āpersonalitiesā and calls them gloomy Tamon and hottie Tamon. Which is honestly pretty upsetting. Would you want someone to call the person you actually are, and not your persona, gloomy? All the time, mind you. And despite learning his true nature, she still worships him only as his idol version, and never cares about the actual person Tamon is - anxious and paranoid and sad. We see this during a scene where he attempts to unalive himself, and she doesnāt care enough to tell his bandmates or manager that heās struggling and to keep an eye on him. Other than giving him some tea to drink, she doesnāt act worried or caring at all...like what? Nor did she call or text and check in with him to make sure he was okay. But then, on the flipside, sheāll constantly say, āI love Tamon.ā Which, obviously she is only referring to his idol version as is clear throughout this whole story. At first, I just brushed it off thinking - maybe she just sees herself as unworthy of Tamon, and thatās why she keeps herself as just his fan and nothing more. But when itās clear that Tamon wants more from her than just a fan/idol relationship, she completely deters his attempts. And I canāt help thinking itās because she doesnāt like āgloomy tamon.ā She doesnāt actually want to change their dynamic because she loves him as an idol, and thatās how she wants it to stay. To only be his fan. Because the real him isnāt hot enough, or confident enough...heās emotional. And itās not the version of him that she loves. I could understand acting this way in the beginning, but then having her slowly treat him as a friend/lover as she gets to know him better. But we donāt get any of that. Even when she tries defending him, she says, āIām his housekeeperā instead of āIām his friend,ā which implies that sheās only spending time with Tamon because he pays her too. And she wouldnāt go out of her way to spend time with him, which we see when that housekeeper goes to take her job back in the earlier episodes, and she stops going to his place because itās not her job anymore. And when she even says that she canāt go to Tamonās place when he invites her over on a regular day, because she can only go when sheās being paid. So sheāll spend her money to see him as Tamon the idol in concert and meet and greets, but she wonāt go over to his house to see him as simply Tamon unless itās for work...like what???? How can you convince me she actually loves him and not his idol-self in the end? Itās incredibly confusing. With that stated, while I definitely had my qualms about Kinoshita, overall I did enjoy and would recommend!
Tamonās B-Side revolves around a concept that idol fans know all too well: the āB-side.ā In music, a B-side is the hidden track. The song that isnāt the headline but often reveals something more personal about the artist. This series takes that idea and turns it into its entire emotional foundation. Behind the dazzling lights, perfect smiles, and carefully curated personas, idols have another side, which is the awkward, insecure, painfully human self that only appears when the stage lights turn off. For Tamon Fukuhara, that contrast is almost comically extreme. On stage, heās the ideal idol. Radiant, confident, effortlessly charming, the kind of presencethat can make an arena of fans scream in unison. But offstage, that shining āPrinceā collapses into something completely different. His private self, nicknamed "Gloomyhara" is a bundle of nerves, constantly overthinking, doubting himself, and hiding in oversized hoodies while spiraling internally over the smallest things. The brilliance of the series lies in this contradiction. The audience sees the glamorous idol everyone admires, but weāre also constantly aware of the anxious boy behind the performance. That tension becomes the beating heart of the comedy. Watching Tamon mentally panic while everyone around him perceives something entirely different is consistently hilarious. Yet the humor never feels cruel. Instead, it reminds us how exhausting it must be to live under the weight of a perfect image. Enter Utage Kinoshita, arguably one of the most entertaining fangirl protagonists in recent memory. Utage isnāt just a fan. Sheās the kind of supporter who pours her entire heart into cheering for her favorite idol. Her reactions are gloriously over-the-top, but thatās exactly what makes her feel real. Anyone who has ever followed an idol group, or even just had a favorite celebrity will probably recognize a piece of themselves in her enthusiasm. What makes the dynamic interesting is how the story flips the usual idol fantasy. Normally, idols are portrayed as the emotionally steady figures who inspire their fans. Here, the roles blur. Tamon may be the idol on the stage, but emotionally he often ends up leaning on Utageās encouragement. The relationship becomes surprisingly reciprocal. Fans might find strength in idols, but idols can also draw strength from the people who believe in them. Beneath the chaos and comedy, the story carries a privately meaningful message, that idols are still human. They are allowed to feel insecure, to grow, to make mistakes, and to have relationships beyond the version of themselves fans see on stage. Loving an idol doesnāt mean owning them, it means supporting them while respecting their boundaries. The series also captures the chaotic joy of fangirl culture with surprising accuracy. Utageās dramatic speeches, emotional outbursts, and near-religious devotion to Tamon are exaggerated for laughs, but they never feel completely unrealistic. If youāve ever stayed up watching idol livestreams, defended your bias online, or felt your heart explode when your favorite member smiled at the camera, Utageās reactions will probably feel hilariously familiar. The anime adaptation amplifies that energy even further thanks to Kana Hanazawa, whose performance gives Utage an infectious spark. Her delivery swings effortlessly between emotional sincerity and chaotic fangirl enthusiasm. Tamon and Utage might be the emotional core, but the rest of the idol group F/ACE ensures the story never loses momentum. Each member carries their own āB-side.ā Ouri Sakaguchiās calm public image hides a mischievous prankster. Keito Tachibanaās composed leadership masks a surprisingly dry sense of humor. Natsuki Ishibashi appears gentle and comforting but secretly overthinks everything. Meanwhile, Rintaro Kaiās cool, minimalist demeanor turns him into the groupās perfect deadpan commentator. Together, their personalities create a chaotic but lovable group dynamic where backstage conversations are often just as entertaining as the performances themselves. Speaking of performances, the anime embraces the energy of idol culture beautifully. Songs like F/ACEās Eyes on You, Sweet Magic, Supernova, etc bring a bright, sparkling atmosphere to the stage scenes, capturing the excitement of live performances while contrasting them with the messy hilarity happening behind the curtain. The animation leans heavily into expressive faces and exaggerated reactions, turning every awkward pause, dramatic fangirl meltdown, and Tamon panic spiral land perfectly. Of course, the series isnāt without its issues. The premise itself is highly idealized. Realistically speaking, meeting an idol in the first place is already incredibly unlikely. Actually forming a close relationship with one? That level of luck probably belongs to people personally chosen by the gods of fortune. In other words, such a close connection with one belongs almost entirely to fantasy. But the story never pretends otherwise. In many ways, that wish-fulfillment is part of the charm. It invites viewers to explore the impossible āwhat ifā scenario every fan has imagined at least once. The romance also unfolds at a relatively brisk pace. While there are moments of conflict, they rarely escalate into heavy emotional drama. Anyone looking for deeply tangled romantic tension might find the story lighter than expected. Similarly, the idol industry itself is portrayed in a fairly gentle light, avoiding the harsher realities that often define real entertainment culture. At times, Tamonās insecurity can also feel exaggerated enough to become a recurring comedic loop. His anxious spirals are funny, but the story occasionally revisits the same joke structure more than necessary. Still, the humor remains charming thanks to the warmth of the characters. In the end, Tamonās B-Side works best when appreciated for what it wants to be. A bright, chaotic romantic comedy that celebrates fandom while gently peeling back the illusion of idol perfection. Behind every dazzling stage persona is a B-side, awkward, vulnerable, and beautifully human. Ultimately, the most comforting idea the series offers is that sometimes the part of someone we admire the most isnāt the flawless performance, but the imperfect person behind it. Anyway, keep in mind that no opinion is ever purely objective, and every perspective remains open to discussion. Even so, each viewpoint still holds its own value. If you happen to see things differently, simple mutual respect is more than enough. That same respect is the spirit behind this reflection as well. Wishing everyone a peaceful day ahead, and thank you for taking the time to read.
8.5/10 +Well rounded heroine with colorful personality; great slow burn romance +Excellent animation, music, and pacing +Supporting cast equally as developed and adds flavor -Somewhat unlikable deuteragonist with eccentric personality -At times crosses the line with inappropriate jokes that underplay mental health Itās easy to idolize what we see on the surface rather than face our true selves. Those deep feelings of wanting acceptance linger in all of us. But what if there was another side you were too afraid to show? When ordinary girl Utage Kinoshita has a chance encounter with her favorite pop idol Tamon, it all seems too good to be true. Yet sheāll discover thatthereās more to him than meets the eye, and perhaps heāll find the courage to finally be himself. Tamonās B Side is truly the definition of a wild ride, standing as one of J.C Staffās best productions to date. Itās funny, itās heartwarming, and the pacing is excellent. Utage especially steals the show with her well rounded personality. Sheās passionate and eccentric while being extremely grounded, yet also caring and sweet. Throw in killer music, smooth animation, a hillarious supporting cast, an awesome slow burn romance, and youāre in for an excellent time. Itās almost perfect, if not for Tamonās outlandish personality and the showās inappropriate digs at depression and anxiety. The finale is also lackluster and there is a lot more blanks to fill with our heroes character motivations. Yet for every incomplete hero, thereās an equally compelling counterpart. For all its faults, Tamonās B Side still delivers, planting the seeds for a rich story.
JC Staff did this, and they did it well. Who would have thought JC Staff still had the touch? Tamon is easily one of the contenders for romance this season. He has all the necessary weapons to defend himself. Something that really stands out about the series is that, despite being based on the idol industry, it doesn't try to be edgy or a social critique. We already know the industry is messed up, but sometimes these kinds of stories are necessary. Stories where idols are humanized and we see their character flaws, while the figure of the fan is vindicated. They can make a serieswhere a fan can be madly in love with their favorite while maintaining respect. Knowing that there's a place for everything, and that even if you lose your mind, you understand that they are people too. The romance works in a very organic way. They don't try to make the viewer fall in love with the perfect version of Tamon. They manage to make us develop a genuine concern for Deprehara episode by episode. We understand the character's vulnerability and the effort behind his perfect facade. We understand why someone like Utage, the protagonist, is there to support him. With a story featuring many handsome guys, the biggest fear might be that it would turn into a reverse harem. Fortunately, that wasn't the case. There is a love triangle, but Utage's connections with the rest of F/ACE aren't romantic. They can establish a friendship between the protagonist and the band members without forcing a romance that wouldn't make sense. The Utage-Tamon relationship is incredibly sweet, and while it doesn't progress much, it's justified. You understand why Utage holds back his feelings so much. We know the kind of scandals that would result from an idol having a girlfriend. Utage holding back his feelings is a way of protecting not only Tamon but the entire band. Meanwhile, we see Tamon trying to break down Utage's barriers, making the romance a constant push and pull. The best part of the anime is that they make Utage develop romantic feelings for the flawed protagonist. She'll always support Tamon of F/ACE as a fan, but the one she fell in love with is Deprehara, the human. The work they do with the band F/ACE is incredibly well done. The fact that they let you get to know each member realistically, with their strengths and weaknesses, makes it easy for you to choose your favorite. Mine is Keito, in case you were wondering. Each member's B-sides are fun to watch; they give them so much personality and complement each other perfectly. Watching their interactions on and off camera is always entertaining because of the contrasts they create. They're a band, so we should also focus on the songs. I'm not just talking about the opening and ending themes, but the songs within the series as well. Rain is a fantastic song that was built up over an entire episode, focusing on Tamon's lack of understanding of love. Rain is easily the best song of the show and the band in general. It's a song that moves away from catchy pop and opts for a ballad that truly touches a nerve. Then there's FLY, which is an homage to Wandance because the 3D modeling in that song gave me flashbacks to Vietnam. Finally, I want to highlight the work of the main voice actors. Utage is voiced by Saori Hayami; it was known even before the premiere that she would be the one to carry this work on her shoulders. Saori knows how to adapt to her characters and give them a lot of charisma and personality. Utage is no exception; she's one of the best female romance protagonists I've seen in recent years. The acting is brilliant; she can shift from comedy to seriousness in a matter of seconds, exactly what the story needs given its fast pace. It was known that Saori Hayami would do an excellent job, and she delivered. But the one who deserves my applause, because his performance was a complete surprise, is Hatano Kakeru, who plays Tamon. Tamon was his first leading role, and he handled it as if it were just another day at the office. Tamon isn't an easy character due to the contrast between his personalities and mood swings. There were fears that the role would be too much for him, but on the contrary, it was a perfect fit. The chemistry he had with Hayami was magnificent. The two voice actors complemented each other exceptionally well, and it shows in the quality of the final product. I'm not a big fan of JC Entertainment; in recent years, they've delivered soulless products just to meet a quota. Watching Tamon's B-side brought back memories of seeing JC Staff from 2008-2015. Without a doubt, when given the time and budget to work, JC Staff can be one of the best choices for a project of this caliber.
