Sky Knight Emergency Whistle Chekhov Summons-Device

Status: confirmed · Technique: chekhov-explicit, prop-tell

The payoff

(A textbook explicit Chekhov device introduced and triggered on-page within one chapter, setting up a Gan Fall intervention in the Upper Yard survival game. Log when read.)

Earliest known caller

(Unknown.)

Why this matters

Oda plants an explicit summons-device and fires it inside the same chapter — the prop is not subtle (the crew openly states its function), which marks it as a deliberate setup for the Sky Knight’s return rather than a background detail. A clean example of the “prop-tell + immediate trigger” pattern.
