I remember being so intrigued by the premise of this series when it was getting ready to air, and so profoundly disappointed by the increasingly bizarre story direction it goes. Regardless, it is not the supernatural mystery romance I wanted, but it is the supernatural, weirdly sci-fi mystery romance someone wanted, and I think that’s lovely.

Where To Start The Detective is Already Dead Light Novel After The Anime?
If you finished The Detective is Already Dead anime and want to continue the story in the light novel, you can start at Novel 4.
Though it is strongly recommended to read the series from the beginning.

The Detective is Already Dead light novel is still ongoing. Since launching in 2019, it usually releases two to three novels per year.
Where To Start The Detective is Already Dead Manga After The Anime?
While The Detective is Already Dead has two manga series, both are concluded. This is the kind of series where each light novel volume, which are usually individual arcs, is adapted into a single manga series. So both Novel 1 and Novel 2 got separate manga adaptations, but Novel 3 has yet to receive one.
What to Expect From The Detective is Already Dead Source Material Compared to The Anime?
It is customary to expect an anime adapting a light novel story to cut a fair amount of details out. Usually, those details are unimportant to the story the series is trying to tell. In The Detective is Already Dead, the anime cuts out a huge amount of details that would make the kind of increasingly unhinged turn it starts taking as it goes on make a little more sense.
Furthermore, the anime sort of shuffles around some events from the light novels it is adapting in not an especially useful way. That just makes things even more confusing.
It is strongly recommended to read the light novels from the beginning for what it skipped if you would like the story to make more sense.
Will There Be A The Detective is Already Dead Season 2?
The Detective is Already Dead has been confirmed to be receiving a Season 2 anime. It has since been announced to air in July 2026.
