The tension finally exploded in the quiet alleyways near the Galley-La shipyards later that evening. While Luffy and the others were negotiating with the shipwrights, three undercover CP9 agents moved in from the shadows to corner Robin and the protagonist in an isolated alley.
Without a word, one of the agents blurred forward using Soru, reappearing directly above the protagonist with his fingers hardened like steel via Shigan. "Target identified. Elimination authorized."
Before the lethal thrust could land, the protagonist's brush flicked through the air with blinding speed. [System Skill: Instant Canvas - Iron-Doped Barrier!] A thick, black shield of solid ink materialized in a fraction of a second. The agent's finger struck the surface, producing a loud metallic clang that sent shockwaves bouncing off the alley walls.
"What?!" the agent gasped, his arm rebounding from the absolute density of the barrier.
The protagonist stepped forward, his pen glowing with the newly acquired 'Ancient World Ink'. "Your Tekkai hardens your body like iron, but my ink takes its properties from whatever I imagine. Let's see whose steel holds up longer."
With a quick series of strokes, the protagonist summoned three ink-forged warriors armed with broadswords, locking the CP9 agents into a high-speed clash of Rokushiki technique against drawn reality, forcing the government assassins to fall back and reassess the true threat of the Manga System.
