Synopsis
There is no kaiju in episode 9 either. Instead, Rooster arrives in an abandoned industrial district drawn by something — the episode doesn't explain what — and finds Shadow Rooster waiting in the middle of a empty lot.
They fight for nineteen minutes.
It ends when Shadow Rooster disengages and walks into darkness. He's clearly capable of continuing. So is Rooster. Neither wants to finish it here.
Dr. Yamada reviews footage captured by a security camera. He creates a third spreadsheet. He labels it "Do Not Show Anyone."
Key Moments
The Fight
Nineteen minutes of the two most powerful beings in the series fighting at full capability. Every move Rooster uses, Shadow Rooster counters — because Shadow Rooster uses the same moves. The choreography is built on near-perfect mirroring, with small asymmetries that accumulate.
The Voice
Shadow Rooster speaks. Once. A single crow — the same register as Rooster's pier crow from Episode 7, not his combat crow. Rooster stops for half a second.
The Departure
Shadow Rooster turns and walks away mid-fight. He doesn't run, doesn't disappear — just walks. Rooster watches him go. He doesn't follow.
Dr. Yamada's Third Spreadsheet
The final scene. Yamada types, stops, looks at his screen for a long time, and closes the laptop.
