Kaiju No. 8 season 2 has 11 main TV episodes, with an additional special that some sources count as a 12th episode.

Quick Scoop

  • The official episode listing and home video info in Japan list season 2 as an 11-episode cour.
  • Anime news outlets and streaming guides also describe season 2 as an 11-episode season.
  • Many fans and sites mention a special episode, “Hoshina’s Day Off,” released separately right before season 2 started airing. If you include that special, some people loosely call it 12 episodes in total.

So, how many episodes?

  • Strictly speaking as a TV season: 11 episodes.
  • If you count the special/OVA that ties into the same storyline: effectively 12 pieces of content.

Extra context and “latest news”

  • Season 2 aired in Summer 2025 as a single cour (one continuous block), which is standard for many modern anime.
  • Episode 11 has already aired and been discussed widely on anime forums, confirming that 11 is the final numbered episode for the season.

Fans on Reddit and forums often debate whether to treat the Hoshina-focused special as part of season 2 or as a standalone OVA, which is why you may see both “11 episodes” and “12 including the special” in discussions.

TL;DR: If your question is “Kaiju No 8 season 2 how many episodes?” the official answer is 11 episodes, plus 1 special if you’re marathoning everything.
