Thousand Sunny Gaon Cannon Main Weapon Debut

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

The seed

The payoff

Why this matters

A named ship-system planted in a paratext cutaway diagram is fired for real ~48 chapters later — the prop-tell that Oda canonizes the Sunny’s arsenal long before deploying it. Pairs with Thousand Sunny Coup de Burst Emergency Acceleration Debut and Coup de Vent Frankys Wind Cannon Debut.
