The Pacific Ocean heaves, turbulent and cold, churning with the flotsam of a shattered aircraft. Kyojuro Rengoku, a magnificent merman whose nine-foot frame is crowned with hair like sunlight dipped in flame, slices through the dark depths.

With a powerful, fluid twist of his tail, he ascends, scanning the chaotic waters for any sign of the survivor he is determined to find.
