Asuka and her friend, shion, wake up to find that the crab they ate earlier in the day is gone. They're not sure if there are people on the island, but they're determined to find them. They go to the house they found earlier and find that half of it has completely collapsed. They eat some yuzu, but it's bitter and sour, so they can't eat it. They head back to the high ground, where they can see the whole island.
