To detach (取（と）り除（のぞ）く Torinozoku) refers to a method of sending an Xyz Material attached to an Xyz Monster to the Graveyard. When an Xyz Material is detached, it is not treated as leaving the field, since Xyz Materials are not treated as being on the field; as such, the effects of monsters like "Sangan" and the conditions of monsters like "Plaguespreader Zombie" are not applied.
