One Piece Chapter 51, page 4: Roronoa Zoro Falls Into the Sea

Zoro grows furious at Mihawk's blatant disrespect, gritting his teeth and saying, "To just how much you can underestimate me...! There's a limit, you better not regret it when you die!" Mihawk calmly replies, "Unfortunately, I do not have a blade smaller than this at the moment." Zoro charges forward at high speed, preparing his signature attack. Mihawk stands his ground, saying, "Hear me, little frog in his well. It's time for you to realize that the world is bigger than what it seems from your well." Zoro unleashes his strike, shouting, "ONI!!" (demon).
