This is not a proper beach, merely a sandbar maybe ten meters long and three wide, with some tall grassy stuff sprouting out of the top. On the other side of it is a brackish lagoon that meanders between banks, not of earth, but of living things all tangled together. That tangle is obviously too thick to penetrate. So, notwithstanding what just happened to the Tokyo boy, Goto Dengo wades into the lagoon, hoping that it will lead inland to a freshwater stream.
