Saint Shalulia, also known as Shalulia Guu, is a female World Noble and the sister of Saint Charloss, as well as the daughter of Saint Roswald. Like other World Nobles, she wears a special suit that supplies her with oxygen to avoid sharing the same air as commoners. Her hair inside the bubble is styled upwards, forming a curl above her head. She also wears a veil over the lower half of her mouth, light-tinted shades over her eyes, and heart-shaped earrings.
She first appears when her slave, Dias, escapes in the Sabaody Archipelago. This incident causes her father to comment on her carelessness for ruining his captain collection. After Dias' explosive collar detonates, she mocks him and shoots him, then walks away, expressing her desire for a giant as her next slave.
Later, she attends the Human Auctioning House with her father, waiting for her brother, Saint Charloss. While the Straw Hats are busy holding off guards, she attempts to kill Camie but is stopped by Silvers Rayleigh, who knocks her out with a burst of "spirit energy."
She is later seen outside the auction house, standing beside her beaten and unconscious father and brother, angrily shouting insults at the Marines for failing to capture the Straw Hats. In her anger, she swears that upon their capture, she will force the pirate crew to beg for forgiveness on the ground before bringing Hell upon them.
