The yacht jerks out from under Hiro's feet, and he hits the deck with his face and shoulder. Getting up, he realizes that either they've just rammed, or been rammed by, something big. There is a thudding noise, feet running on the deck. Hiro hears some of these feet near him, drops his wakizashi, pulls his katana, whirls at the same time, snapping the long blade into someone's midsection. Meanwhile they're dragging a long knife down his back, but it doesn't penetrate the fabric, just hurts a little. His katana comes free easily, which is dumb luck, because he forgot to squeeze off the blow, could have gotten it wedged in there. He turns again, instinctively parries a knife thrust from another greaseball, raises the katana and snaps it down into his brainpan. This time he does it right, kills him without sticking the blade. There are greaseballs on two sides of him now. Hiro chooses a direction, swings it sideways, decapitates one of them. Then he turns around. Another greaseball is staggering toward him across the pitching deck with a spiked club, but unlike Hiro he's not keeping his balance. Hiro shuffles up to meet him, keeping his center of gravity over his feet, and impales him on the katana.
