One Piece Chapter 51, page 10-12: Roronoa Zoro Falls Into the Sea

Johnny and Yosaku are outraged by Mihawk's words, yelling, "How dare you call our Bro a weakling!? We oughta teach you a lesson, you bastard!" They prepare to draw their swords and jump into the fight, but Luffy holds them back, shouting, "Stop, Yosaku! Johnny! Don't interfere! Stay put right here...!" Usopp watches anxiously, murmuring, "Luffy..." Zoro charges at Mihawk once more, but Mihawk thrusts his dagger forward, striking Zoro with a heavy "OOF!" sound.

Zoro prepares his next attack, raising his swords high and declaring, "TORA" (tiger) "GARI" (hunting). Luffy watches with a wide, proud grin, shouting, "World's strongest swordsman! Sounds great!

Luffy grits his teeth in agony, groaning, "Nghh!" Despite the blade piercing his chest, Zoro stands firm, clenching his swords tightly, refusing to back down. Mihawk looks at him in surprise.
