Detach

Detach refers to the act of separating an Xyz Material attached to an Xyz Monster either as a cost or by an effect (that uses this term), sending it to the Graveyard as a result.

When a Xyz Material is detached, it is not treated as it leaving the field, since Xyz Materials are not treated as being on the field; so the effects of monsters like "Sangan" and the conditions of monsters like "Plaguespreader Zombie" are not applied.

However if the effects like Makyura the Destructor of simply being sent to the graveyard and dose not matter if it was on the field in your, discarded from your hand or used as Xyz Material and then Detached. the effects are applied, because it was sent to the graveyard either way.
