Anime & Character Rankings

Best Thriller & Mystery Anime — Ranked by Fans

IntoSome anime stay with you long after the credits roll. Not because of flashy fight scenes or lovable mascot characters, but because they got inside your head and refused to leave. Thriller and mystery anime occupy a special corner of the medium — one built on tension, deception, and the creeping feeling that nothing is quite what it seems. This is the genre that keeps you watching at 2 a.m. telling yourself "just one more episode" while the plot systematically dismantles everything you thought you understood.This list ranks the best thriller, mystery, and suspense anime as rated by fans. From psychological mind-benders that blur the line between reality and delusion, to locked-room whodunits built on pure deductive logic, to slow-burn crime dramas that unfold across entire continents — every entry here earns its place by doing one thing exceptionally well: making you feel the tension in your chest.What separates a great thriller anime from a good one?Pacing and payoff. A thriller lives or dies by what it chooses to reveal and when. The best mystery anime plant clues early enough to be fair, obscure them cleverly enough to surprise you, and then stick the landing with a twist that reframes everything you just watched. The worst ones withhold information arbitrarily and call it suspense. The entries on this list belong firmly in the first category.The genre spans a wide spectrum. On one end you have psychological thrillers like Death Note and Monster, where the horror is entirely human — a notebook that kills, a surgeon hunting the monster he accidentally created. On the other end sit supernatural mysteries like Mushishi and Mononoke, where the unknown itself is the source of dread. In between lives everything from dystopian sci-fi thrillers to Prohibition-era mafia revenge dramas to a mystery anime disguised as a show about an antisocial walrus driving a taxi. Yes, really — and Odd Taxi might be the smartest mystery anime of the last decade.How this ranking worksEvery title on this list is ranked by user ratings and reviews from fans who have actually watched and scored each series. No editorial gatekeeping, no algorithm deciding what's "objectively" best. If a beloved classic sits below a recent underdog, it's because the fans spoke.

Whether you're a longtime fan of the genre or someone who just finished Death Note and is desperately looking for what to watch next — you're in the right place.
