One Piece Chapter 39, page 2-4: FOR WHOM THE BELL TOLLS

Luffy lets out a thunderous roar that echoes across the entire cliffside (SFX: GOOOO...): "COME OUT, YOU EVIL BUTLER!!!" The sound reverberates down the slope where dozens of defeated pirates lie scattered. Luffy suddenly stops and looks around, sensing a sudden movement. A sharp swooshing sound cuts through the air (SFX: SWOSH! / SFX: HYU...), followed by a sudden, heavy metallic clash (SFX: GAKI-N!!).

Kuro attacks with blinding speed, his clawed gloves slicing through the air. Luffy is caught off guard by the sheer velocity of the strike, crying out "UUH!!!" and "AHHHH!" as he is forced to dodge and defend against the invisible onslaught. Kuro's deadly cat claws gleam as they slash wildly around Luffy.

Kuro unleashes a flurry of high-speed slashes (SFX: ZUBAAA!), tearing up the ground around them. Amidst the chaos of flying dirt and debris, Luffy manages to track Kuro's movements and lunges forward, wrapping his arms tightly around the butler. Luffy grins triumphantly and declares, "GOTCHA!" Kuro is left completely stunned and immobilized ("!?").
