The expression to "spirit away" means to remove without anyone's noticing.
Kamikakushi (神隠し, lit. "hidden by gods") means "spirited away". Kamikakushi, in Japanese folklore, is used to refer to the mysterious disappearance of a person that happens when an angered god takes a person away.
In the anime film Spirited Away (千と千尋の神隠し Sen to Chihiro no Kamikakushi, Sen and Chihiro's Spiriting Away), the main protagonist, Chihiro, is "spirited away" from reality to the spirit world.
