UMI NO MISAKI

Goto Nagi has travelled to the southern island of Okitsushima, and ventures out to see Umi no Misaki, a striking cape jutting out into the ocean. But when he arrives, he finds that there is much more to this cape than a wondrous view. There is something peculiar about the cape, and about the island's inhabitants.
