Forum:Jinzo - Returner effect???

The card effect is Jinzo-returner. I confuse about it effect.

“This card can attack your opponent directly. When this card is sent to the Graveyard, you can Special Summon 1 "Jinzo" from your Graveyard. Destroy it during your End Phase.”

Is this phase "Destroy it during your End Phase" means to destroy Jinzo-Returner itself at the end phase? Or mean to destroy "Jinzo" at the end phase after Jinzo-returner special summon "jinzo" on the field ? Thank you anyway.
