Here’s a short review you can use or adapt, depending on the platform (e.g., Google, MyAnimeList, Reddit):

37 episodes total for the anime. If someone tells you more or less, they’re counting OVAs, movies, or spin-offs.

Clear answer for “¿Cuántos capítulos tiene Death Note?”

If you’re looking for the exact number of episodes Death Note has, here it is: 37 episodes (plus 2 recap specials and optional live-action/musical adaptations, but the main anime has 37).

The series covers the entire original manga from start to finish. No filler arcs—just tight, psychological cat-and-mouse action. Some people feel the story changes after episode 25, but the total count remains 37 canon episodes across all seasons (there’s no “Season 2” in the traditional sense; it’s one continuous run).
