1) Monster
If you only watch one entry here, make it Monster. This is the gold standard for “slow-burn psychological mystery that eats your entire weekend.”
It starts with a surgeon making one ethical choice… and then the story grows into a haunting cat-and-mouse chase across Europe involving identity, trauma, manipulation, and a villain so chilling you’ll feel your room temperature drop.
Why it hits: layered mystery, morally gray choices, insanely grounded tension.
Best for: people who like serious, realistic thrillers with long payoffs.
Mood: “I need to lie down after this episode.”
2) Death Note
Yeah, it’s popular. Yeah, you’ve heard of it. But it still belongs here because it’s basically a mystery show where both sides are geniuses trying to outplay each other.
A teen finds a notebook that can kill anyone whose name is written in it. A detective known only as “L” tries to catch him. What follows is a mental chess match that defined a whole era of anime fandom.
Why it hits: mind games, iconic characters, nonstop tension.
Best for: newcomers and anyone who loves strategy battles.
Mood: “I’m smarter than everyone (I’m not).”
3) Steins;Gate
Time travel stories are basically mysteries in disguise. You’re constantly asking: What changed? Who knows what? What’s the real timeline?
Steins;Gate starts goofy and chaotic—like a bunch of nerds messing around with a microwave—then slowly turns into a full-on emotional thriller where every choice has consequences.
Why it hits: satisfying puzzle-box plotting, huge emotional gut punches.
Best for: people who can handle a slow build early on.
Mood: “This was funny… wait why am I crying?”
4) Erased (Boku dake ga Inai Machi)
A guy can “jump back” minutes in time to prevent tragedies—until a massive event sends him back to his childhood, right before a series of kidnappings and murders.
This one is bingeable in the most dangerous way. Like, “I’ll just watch one more” and suddenly it’s 4 AM.
Why it hits: strong emotional core, suspense, childhood mystery vibes.
Best for: people who like murder mystery mixed with heart.
Mood: “Protect the kids at all costs.”
5) Odd Taxi
Don’t let the animal character designs fool you. This show is sharp, grounded, and quietly brilliant.
A taxi driver gets tangled in a missing girl case, and every passenger is connected in ways you don’t realize until the puzzle snaps together.
Why it hits: tight writing, realistic dialogue, satisfying payoff.
Best for: people who like modern, twisty, character-driven mysteries.
Mood: “Wait… that line from episode 2 matters?!”
6) Psycho-Pass (Season 1 especially)
In a world where your crime potential can be measured, investigators hunt criminals before they act. Sounds “efficient,” right? Totally not dystopian at all. Definitely won’t create horrifying ethical dilemmas. (Spoiler: it does.)
Season 1 is a mystery thriller wrapped in social commentary, with one of the most memorable villains in modern anime.
Why it hits: atmosphere, moral questions, strong cases and arcs.
Best for: fans of sci-fi noir and conspiracy vibes.
Mood: “Society is a scam, but make it stylish.”
7) Paranoia Agent
This is mystery anime if mystery anime drank three energy drinks and started talking about modern anxiety.
A mysterious attacker known as “Lil’ Slugger” shows up across different people’s lives. But the deeper you go, the less stable the truth feels.
Why it hits: psychological weirdness, social themes, surreal dread.
Best for: people who like artsy mind-benders.
Mood: “Am I the one being attacked?”
8) Hyouka
Not all mysteries need murder. Hyouka is about small, everyday puzzles—missing pages, odd behaviors, school legends—and the quiet thrill of figuring things out.
It’s gorgeous, calm, and oddly addictive. Plus, the characters have chemistry that feels genuinely human.
Why it hits: cozy mystery energy, clever writing, beautiful animation.
Best for: people who want “detective vibes” without the trauma.
Mood: “Let’s solve a mystery and then go get snacks.”
9) Gosick
A gothic European-inspired setting, a genius girl solving crimes from a library tower, and a bunch of mystery arcs that feel like classic detective novels with anime flair.
It’s dramatic, stylish, and a lot of fun if you like that old-school vibe.
Why it hits: detective formula done well, strong atmosphere.
Best for: fans of period settings and elegant mysteries.
Mood: “Tea, secrets, and suspicious aristocrats.”
10) Detective Conan (Case Closed)
This is the marathon mystery series. If you want a huge library of cases (and you love that “clue -> reveal” structure), you can live in Conan forever.
Why it hits: endless mysteries, satisfying episodic structure.
Best for: people who want long-term comfort viewing.
Mood: “Just one case… okay five cases.”
11) The Promised Neverland (Season 1)
Kids in an orphanage discover something is very, very wrong. The fun part is watching them plan, adapt, and outthink a system designed to trap them.
Season 1 is a masterclass in tension and reveal pacing.
Why it hits: suspense, clever strategies, dread that builds perfectly.
Best for: people who like “escape plan” mysteries.
Mood: “Smile through terror.”
12) Made in Abyss
This one is gorgeous and horrifying, sometimes in the same scene.
It’s mystery in the sense that the Abyss is a giant question mark: What’s at the bottom? What are the rules? Why does it change people? The deeper the characters go, the more the world reveals… and the more it takes.
Why it hits: worldbuilding mystery, emotional stakes, unforgettable atmosphere.
Best for: fans of dark fantasy and exploration.
Mood: “Pretty… PRETTY SCARY.”
13) Another
Small town. Transfer student. Class curse. People start dying in freak “accidents” that are… not really accidents.

Why it hits: creepy atmosphere, constant suspicion.
Best for: horror fans.
Mood: “Don’t touch the umbrella.”

It explores identity and reality in a tech-heavy, philosophical way that still feels weirdly relevant.
Why it hits: unsettling mood, layered interpretation, internet-age themes.
Best for: patient viewers who like ambiguity.
Mood: “The Wi-Fi is haunted.”

Why it hits: big reveals, worldbuilding mystery, moral complexity.
Best for: people who like dark, philosophical stories.
Mood: “Everything is a lie (probably).”

Still, if you want something fast, dramatic, and twisty, it scratches the itch.
Why it hits: constant reveals, courtroom energy, wild personalities.
Best for: people who like chaotic mystery drama.
Mood: “Objection! Screaming! Despair!”
23) The Apothecary Diaries (Kusuriya no Hitorigoto)
Mystery in a palace setting, with poison tests, political intrigue, and a main character who’s basically a gremlin pharmacist genius.
