Madam Shyarly

Shyarly is a sizable mermaid who wears purple polish on her nails and red lipstick, with blue eyes whose slanted pupils call to mind a shark's gaze. Anger gives those eyes a sinister cast and bares her sharp teeth. Black hair, kept short, drapes over the right half of her face. Her tail runs dark blue, fitted with a dorsal fin where her upper and lower halves meet, a white patch beneath it, and a crescent-shaped caudal fin. She typically dons a hooded purple blouse fastened only at the middle, leaving her midriff and cleavage exposed, along with a chain about her waist, and a pipe is frequently in her hand.

Warm-hearted by nature, Shyarly offered the visiting Straw Hats a spare room to nurse Sanji even though they had beaten her brother, and she granted Camie time off to spend with friends. Coarse or crude behavior bothers her, and she flew into a rage when Luffy asked whether mermaids defecate, though the temper faded the moment he apologized. She regards her gift of foresight as a heavy weight, since most of what she sees is grim, and so she holds that the future is best left a mystery. Despite quitting, curiosity drove her to peer into Luffy's fate, and the vision of a straw-hatted man destroying the island sent her into a panic. Unlike Arlong, she harbors no blanket hatred of humans, urging the island's children to judge by their own eyes rather than by hearsay.

Left behind by her father in her early years, Shyarly grew up under the care of Arlong, then a teenager, within the Fish-Man District. By the age of three she foresaw the eventual birth of the Mermaid Princess and informed Gol D. Roger it would occur within a decade, and at four she predicted the dawn of the Great Pirate Era, which arrived a year afterward. She also accurately called Whitebeard's death and the outcome of the war at Marineford. When the Straw Hats reached Fish-Man Island, she lent them the back room of her cafe for Sanji's recovery, then glimpsed a straw-hatted figure razing the island and rushed into the streets demanding the crew be driven off.

Once Hody's New Fish-Man Pirates seized control, Shyarly faced Hody Jones directly and calmly declared that Luffy, not Hody, would be the island's destroyer, an assertion that enraged him into striking her down with a water shot. Once the conflict was settled, she shattered her crystal ball, vowing never to read the future again and hoping her final prophecy about Luffy would prove false.
