Akagi's final thoughts as he dies are 'What's this? Dying is not that scary after all...' He opens his eyes one last time, and then closes them.
After Akagi dies, gamblers secretly take bits of his gravestone for good luck, and so the shape is all ruined. Ten says, "Forgive them, Akagi.. they're doing that because they all like you". Ten and Hiro (another main character) leave the graveyard, and Hiro says that Akagi Shigeru is still in everyone's minds. A cat comes by and sleeps in front of Akagi's now damaged gravestone.
