Kimihiko Kimizuka has found himself inadvertently entangled in various crimes more times than he can remember, referring to himself as a magnet for trouble. One day, as if it was nothing out of the ordinary, a group of unknown men kidnaps him, forcing him to board a flight—where he also encounters a hijacking. Amid the resulting chaos, however, Kimizuka meets a stunning silver-haired beauty, going by the codename Siesta, who then saves the day.

Claiming to be a legendary detective, Siesta enlists Kimizuka to be her sidekick. Though Kimizuka refuses at first, with Siesta's insistence, he eventually joins her—marking the start of a grand adventure spanning the entire world, preventing multiple threats that could spell doom for humanity along the way.

Unfortunately, after three years of their unpredictable yet enjoyable time together, Siesta abruptly passes away. Distraught, Kimizuka tries to leave all memories of her behind, but as he begins to meet more people, it seems that Siesta's influence will never truly die.

This show is totally fucking with us.
The main girl is named Siesta. “Siesta” is Spanish for “nap.”
And this show does nothing but put you to sleep.

But that’s only if you’re lucky, because staying awake is torture. I know “The Detective is Already Dead” may sound like an enticing title, but don’t be fooled. This is a battle harem. It may not be set in an academy, and there may not be an arena for waifu fights, but the essential elements are there, and the show isn’t ashamed of this at all. In fact, it’s the only selling point. Why is a show about a read more

The Detective is Already Dead gives off an ambigious feeling of uncertainity. And by that, I do mean how potential viewers should expect from the show altogether. Let's face it, the English title should also fire some questions into your head. You may be asking yourself why the detective is 'already dead' or who really dies in the show. In what seems like a thematically intriguing premise quickly turns sour when we realize just how mediocre this actually turned out to be.

Taking a step back, I didn't want to be judgmental at first glance. In fact, I was actually impressed by some of the promotional read more

Between the good anime and the enjoyably bad anime sit the ones that are unremarkable in every way, and you can’t help but wish you hadn’t wasted your time watching it. The Detective is Already Dead fits this role perfectly. With one-dimensional characters, an unengaging story, and plain awful visuals, there is next to no praise that can be given for the series. Don’t worry though, as it makes up for this by making sure there’s at least one cute girl in every scene.

There is an abundance of poorly directed scenes that lack the intended impact that they were going for. The moments that are read more

The detective may be already dead, but this entire show was already dead from the beginning.

Tanmoshi was one of the most highly anticipated anime series from the year 2021, but ultimately ended up as one of the most disappointing and underwhelming shows, instead. With how the anime industry’s priorities are, it was doomed to be a failure from the start, and this isn’t anything new at all, especially with most light novel adaptations. However, Tanmoshi, also known as Tantei Wa Mou Shindeiru / The Detective Is Already Dead, has more inherent problems aside from the typical issues with adapting light novels. Keep in mind that read more
