Meet the characters from The Detective is Already Dead

Nagisa Natsunagi

Okay, Nagisa is basically this whirlwind of stubborn sunshine — like, she crawled out of a rom-com and decided to solve mysteries on the side. She’s brave and dramatic and will march into danger with a smile and a snack (she’s always got snacks, sometimes three at once). She tries to act all mature but then cries at the smallest movie scene and will absolutely start a full-blown argument about the correct way to make tea. Also weirdly nostalgic about old cassette tapes? I’m not sure where that came from but it feels very Nagisa.

Charlotte Arisaka Anderson

Charlotte is refined chaos wrapped in a pastel coat — proper, elegant, and low-key terrifying when she gets serious (soft voice, deadly resolve). She’s got this old-world charm, loves tea and manners, yet somehow has the worst poker face and blubs into her handkerchief at random rom-com lines. Nobility vibes but also reads trashy detective novels under the table; she will judge you politely and then steal your dessert. There’s a tiny rebellious streak too — like, perfectly tied hair with one lock defiantly loose.

Yui Saikawa

Yui is sunshine and caffeine and honestly will adopt you if you’re sad — hyper-supportive with a terrifyingly energetic smile. She’s weirdly into gadgets one minute and into baking the next, and somehow both hobbies look like chaos but somehow work out (mostly). Quick to butt in, quicker to forgive; she has surprising steel when pushed, although she’ll insist she’s just “cheering very loudly.” Also keeps a suspicious number of plushies in places that make no sense — on the bike, in the toolbox, in the fridge once.

Siesta

Siesta is the cool, moody detective legend and yes she is as stylish and mysterious as people say — a living, sarcastic anthology of noir vibes. She’s efficient, slightly deadpan, has a weird soft spot for dumb jokes and stray cats (don’t tell anyone though, she’d deny it). There’s this melancholy underpinning to her that makes everything she says feel like a secret, and yet she’ll order the sweetest dessert on the menu and eat it like she’s committing a small crime. Oh, and she’s ridiculously good at folding napkins? No, really, that’s a thing.

Fubi Kase

Fubi is the quiet, dependable type with an unexpectedly scenic obsession with clocks and classical music — who knew? Methodical, a little mysterious, and always calm even when everything else is burning down (which, let’s be honest, happens a lot around them). He has a dry sense of humor that sneaks up on you and once fixed a broken radio with chewing gum and pure willpower, so don’t underestimate him. Also sometimes contradicts himself by being hopelessly romantic in private letters that he absolutely swears he never wrote.

Kimihiko Kimizuka

Kimihiko is such an unassuming normal guy until he isn’t — mild, kind, a literal magnet for mayhem, and also secretly the steady spine of the whole mess. He’s practical, a touch stoic, but will go full-on soft mode over people he cares about (silent worry looks are his superpower). He dislikes drama but attracts it like a moth to a neon sign, and somehow survives everything with snacks and a bewildered expression. Also very into weird hobby cooking experiments — might give you a weirdly tasty sandwich made of three things that shouldn’t go together but do.

Koumori

Koumori is delightfully odd: shadowy, playful, and does things at weird hours like a bat that steals your keys and your heart. Enigmatic with a smirk, they love riddles and sweets and turning up when you least expect them to, usually wearing something that looks like it shouldn’t match but absolutely does. They’ll talk in teasing one-liners and then drop a sincere truth that makes you pause — and then vanish to get a midnight snack. Slightly contradictory habit: claims to hate attention but thrives on theatrical entrances, forever the mysterious scene-stealer.
