Yukiko Sasaki (佐々木 由貴子 Sasaki Yukiko) is the Sweets Gaia Memory user.
She is a maid at the Sonozaki estate with a sweet tooth that she cannot satisfy, only able to be a food critic instead of a pâtissière because she could not cook very well. As her Dopant form, Yukiko kidnaps the top pâtissiers hired by the Sonozaki family by dragging them in her "Sweets Cream" (スイーツクリーム Suītsu Kurīmu) state to a small building on the grounds to make pastries only for her.
However, when Akiko attempts to weed out the wrong culprit with her sweets, Yukiko kidnaps her with Mai Asakawa, the daughter of her previous victim. Though intending to kill Akiko for disgracing her love for sweets, the Sweets Dopant is battered by Akiko using a chair before Kamen Rider Double finishes her off with HeatJoker's Joker Grenade Maximum Drive.
