The fan theory squad.
What does kousatsu han mean?
The people who pause every frame, zoom in on a reflection and post a timeline before you've finished the episode. Nobody appoints them; they simply appear.

The story behind kousatsu han
Both halves are borrowed from school. 考察 is the heading on the discussion section of a lab report, the part where you argue about what the data meant. 班 is the group your teacher assigned you to in elementary school, the one with a rota and a leader. Together they describe a research unit that nobody convened.
They materialise within minutes of any mystery-shaped release, pausing on single frames, enlarging reflections and posting a full timeline before the rest of us have made tea. The 2010s wave of puzzle-box series gave them their golden age, and creators now write knowing they are out there — a gift and an arms race at once.
