Which Voice Actors Play My Senpai Is Annoy Characters?

I’m the kind of fan who gushes about little details, so let me dive into the heart of 'My Senpai is Annoying' the way I’d tell a friend over coffee. Futaba Igarashi: She’s tiny but fierce in the best possible way. The show paints her as a competent office worker who’s constantly underestimated because of her height and quiet look, which feeds into a lot of her inner tension—she wants to be taken seriously at work but also gets flustered by Takeda’s obvious attention. I feel for her because she balances professionalism with a very human awkwardness; that mix makes her growth (learning to accept compliments, standing up for herself socially) feel earned rather than sudden. Harumi Takeda: On the surface he’s loud, goofy, and impossibly tall—basically everything Futaba isn’t. But the series drops small clues that he’s protective and reliable, the type who’s always been expected to handle things for others. I like imagining a backstory where he learned responsibility early, maybe as the dependable friend or sibling, and uses humor to bridge distance. Their dynamic reads like two people learning to translate each other’s languages: his straightforwardness vs. her tendency to overthink. Supporting cast (Matoba and coworkers): The calmer, glasses-wearing coworkers act as foils—some tease, some steady the pair. Matoba’s dry teasing suggests a comfort with the group that comes from long familiarity; the boss’s occasional obliviousness highlights how Futaba and Takeda actually carry the team emotionally. All together, their histories don’t need sprawling origin tales—small shared experiences at the office form the backbone of their relationships, and that’s what I love about the show.

Seeing the way characters change in 'My Senpai Is Annoying' is honestly one of the sweetest parts for me. If I had to pick who grows the most, I'd put Futaba Igarashi at the top. She starts off super timid and anxious about tiny things—like her height and how people perceive her—but over time you watch her find a steadier confidence at work, speak up more, and even tease back sometimes. Those little moments when she sets boundaries or proudly finishes a task that used to fluster her? They add up, and they feel real. Kurose comes in a close second. He’s always been kind, but his growth is more about peeling back layers: the way he learns to show vulnerability, take things seriously outside of joking, and accept that his teasing can be clumsy. The supporting cast shifts subtly too—co-workers who once felt like background now get textures and backstory. If you’ve only seen the anime, the manga gives you extra beats where these advances land harder, so I usually tell friends to binge the show and then savor the manga for more growth scenes.

I still get a little giddy when I think about 'My Senpai is Annoying'—it's such a cozy mess of warm comedy and low-key romance. For me the top favorite is absolutely Futaba Igarashi; her deadpan expressions, sudden panic modes, and tiny-but-spirited reactions are peak relatable. I love how she stomps around the office world while trying to act mature, and how those moments of fluster turn into genuine, quiet growth. Right behind her is Harumi Takeda. Fans adore him because he’s this giant soft guy who can be casually crushing in the most unintentional ways. The gap between his intimidating size and his caring gestures is classic 'gap moe' and it fuels so many memeable scenes. Beyond the leads, people also fangirl over the supporting coworkers — the teasing colleagues, the stoic manager who occasionally surprises everyone, and the one-liners that break up the workplace routine. Shipping culture is alive here; the slow-burn intimacy between Futaba and Takeda gets fanart, headcanons, and cosplay love. Honestly, it’s the small, everyday details that make the cast so beloved; they feel like coworkers I’d want to bicker with over lunch.

I get ridiculously excited whenever someone asks about cosplaying from 'My Senpai Is Annoying'—it's one of those series where the outfits are simple but the personalities sell the whole look. If you want something instantly recognizable and low-stress, go for Futaba Igarashi: school-cute vibe meets office-kawaii. A well-fitted white blouse, a simple pencil skirt, and that slightly oversized cardigan are all you need. Focus on the little things: the short blunt-cut wig with fringe, soft natural makeup with a blush-heavy, flustered expression, and maybe a tiny name badge or a stack of office documents as a prop. Her body language—awkward, embarrassed, then brightening—is the cosplay's secret sauce. For people who like a challenge but still want comfort, the senpai outfit (the tall, laid-back office type from 'My Senpai Is Annoying') is perfect. A crisp suit or a neat work shirt with rolled sleeves, a loose tie, and a coffee tumbler prop give you the vibe. The key is posture and those gentle, slightly exasperated smiles. If you and a friend want duo cosplay, Futaba + the senpai is pure chemistry on stage. I’ve done the kouhai once and loved how small expression tweaks made strangers recognize the characters immediately; it’s great for photos and for banter at panels.

Honestly, the heart of 'My Senpai is Annoying' is a tiny, perfect office triangle: Futaba Igarashi and her massive, lovable senpai, Takeda. Futaba is the earnest, pint-sized kouhai who's constantly trying to act professional despite being flustered by how obliviously doting Takeda can be. Takeda (the senpai) is the big, gruff coworker who treats Futaba like a kid sister — intentionally teasing, protective, and somehow both annoying and comforting at once. Beyond that duo, the anime leans on a steady stream of coworkers who round out the cast: a few other seniors who offer advice, office friends who stir things up, and a manager or two who provide background humor and workplace context. These supporting folks don’t always get the spotlight, but they’re crucial for the slice-of-life vibe — they give the main pair room to bicker, grow, and show little moments of warmth. I always find myself smiling at the small interactions as much as the big gestures; the chemistry between Futaba and Takeda is what keeps me coming back.

There’s a cozy weirdness to why people fall for characters from 'My Senpai is Annoying' that gets me every time. On the surface it’s the classic big, goofy senpai / flustered kouhai setup, but what hooks me is the tiny, everyday details—the way a shoulder squeeze says more than a confession, or how a shared bento becomes a whole scene of care. Those small gestures feel earned, and I love that the show trusts quiet moments as much as punchlines. I tend to rewatch a scene when I need something warm, and the timing of the comedy is perfect for that. The senpai’s bluster and the kouhai’s mortification create this dance where you can laugh at them and also want to hug them. The voice acting and expressive faces sell the emotion without shouting it, and the workplace setting grounds the romance in something relatable. If you’ve ever had a coworker who’s loud but oddly considerate, you know exactly why it resonates. Honestly, it’s also a comfort show for me: short episodes, a predictable-but-satisfying rhythm, and characters who grow without melodrama. I’ll keep coming back to it on rainy mornings and when I need a soft pick-me-up.

Whenever I flip through a manga panel of a pushy, oblivious senpai I find myself grinning at the tiny details that never fully survive a straight cut to animation. In the manga the annoyance often lives in the pacing and in inner monologue — those little captions, eccentric lettering, and timing between panels that let an expression hang for a beat. Artists can stretch a blink to feel eternal; a smug grin can be three panels long where you stew in the awkwardness. The anime, by contrast, has seiyuu, music, and motion doing the heavy lifting. A voice actor can turn a grating line into something oddly charming or make a supposedly-cold senpai feel sympathetic. Background score cues and timing edits change how long you dwell on embarrassment or irritation, so a manga's slow-burn cringe might become a quick, punchy gag in the show. I love both forms for different reasons — the manga for its precise, intimate beats and the anime for its immediacy and personality. If you want the pure, raw flavor of someone being actively annoying, read the panels slowly; if you want the full performance (awkward pauses, tone, and musical sting), watch the episodes and enjoy the ride.

I still get a little giddy thinking about how the cast of 'My Senpai Is Annoying' blew up after the anime came out. From my perspective, the main duo—Futaba Igarashi and her senpai, Takeda—usually sit at the top of any show-specific popularity list. On sites like MyAnimeList and Pixiv they often dominate the fan art, bookmarked illustrations, and character pages. If you check seasonal character polls on Twitter during the show's broadcast, you'll typically see them in the upper ranks for that season, even if they don't crack the absolute top spots across all anime that year. That said, broader industry charts (think magazine polls like 'Newtype' or nationwide sales/merch rankings) treat them differently. They perform very strongly among slice-of-life and romcom fan communities, and they get a boost from shipping culture and cosplay presence at cons. So, in short: top within their show and genre, solid presence in seasonal character charts, and occasional spikes in bigger publications depending on releases and merch drops.
