Captain of the Glomar, she is also the head supervisor in the ship's marketing business as well as the Chief Operator of the Glomar's controls. Upon discovering Kei as an Idiosynchratic Point by Jabby, she is given orders to deliver Kei to the Emaan homeland as soon as possible. Shaya follows faithfully the Emaan customs and culture. Among those customs is dressing and taking baths even with men present and never being shy about it, which gives Kei an uncomfortable position of being a pervert when he and Shaya are together (this is because of the Emaan's biological nature as Emaan women lose their fertility at age 18, which at that point they are no longer courted by Emaan men and are considered no longer as 'females'). Her family, along with Mimsy's family, runs the Emaan country.
