A talking-animal mystery where every seemingly unrelated passenger conversation turns out to be load-bearing, and the payoff depends on dialogue you heard in episode two and did not think about again.
What the story actually is
Odokawa is a walrus who drives a taxi in Tokyo, sleeps badly, and speaks to almost no one outside his cab. The series opens as a set of loosely connected character sketches: an aspiring comedian duo, a college student sinking into a gacha game, a nurse, a small-time gangster, an idol group manager. None of them appear to be in the same story.
They are. A missing girl case runs underneath every one of those threads, and the show spends thirteen episodes tightening the knot until the connections are undeniable. What makes it unusual is that the mystery is not solved through investigation. It is solved because the audience finally has enough overheard conversation to assemble it.
The writing is the production value
Odd Taxi is not a lavish show. Character animation is functional, backgrounds are flat, and most scenes are two people talking in a car. The budget went into script density and voice performance instead, and the trade is worth it.
Screenwriter Kazuya Konomoto structures nearly every episode as a series of conversations that read as digression on first watch and as evidence on second. Dialogue overlaps, characters lie casually, and the show almost never underlines what matters. Very few anime trust the audience this much.
Why the animals matter
The anthropomorphic design is not decoration and it is not a stylistic whim. It is doing specific narrative work, and the final episodes make explicit what that work is. Saying more spoils the single best structural reveal in the series.
What can be said safely: the choice affects how you read every character's face for twelve and a half episodes, and rewatching with the answer in hand genuinely changes scenes rather than merely confirming them.
Who should watch it
Watch it if you like crime fiction that rewards attention, ensemble stories where minor characters get real interiority, or shows built on conversation rather than incident. It sits closer to a Coen brothers film than to a typical anime thriller.
Skip it if you need forward momentum in every episode. Several instalments are almost entirely setup, and their value only registers later. It is also worth avoiding summaries and thumbnails, because this is a show that spoils easily.
