The Detective Is Already Dead (Seasons 1–2)

The Detective Is Already Dead (探偵はもう、死んでいる, 2021) is a Japanese mystery-drama anime you can watch online on iFILM. High schooler Kimihiko Kimizuka is a magnet for trouble, so when his flight gets hijacked, he's barely surprised to be roped in by a silver-haired girl who calls herself Siesta.

She declares herself a detective and drafts Kimihiko as her assistant on the spot. What follows is three years of globe-spanning cases — criminal syndicates dismantled, disasters averted, thousands saved. Then the title makes good on its promise: Siesta dies, leaving the boy to carry her unfinished business. Just as he settles into an ordinary life, a girl who looks unnervingly like her crashes back into it.

Adapted from the hit light novels, the show blends adventure action with a real ache of grief — not a pairing the genre tries often. Worth a look if you like mysteries where the puzzle circles the detective herself. Stream every episode of The Detective Is Already Dead online on iFILM.
