Kaiju No. 8 discussion tips

  • Agree on sub vs. dub for the room so reactions line up with audio.
  • Use "no spoilers past episode N" in the room title when someone is behind.
  • Drop short reaction notes right after the cold open and before the credits—those are the beats people replay.
  • Save big lore debates for after the eyecatch to avoid late joins getting spoiled.
