Name: Heart Piece
Availability: Arrancar Specific
Looks: The Heart Piece appears as a simple heart shaped container the size of the person's hand.
Description: This invention is the Arrancar version of a Gigai. It allows an arrancar to walk around the mortal realm while in a 'human' body. In order for it to be used, the arrancar must place the container into their hollow hole where it will forcibly close their hollow hole, giving them a human body. However there will be a heart shaped mark where their hollow hole was. However it will not remove their mask fragments, but, depending on the location, they will appear as simple tattoos. It will also mask their presence, though the powerful espada are still detectable by Lieutenant class or higher. In order to get out of the Heart Piece and return to their Arrancar body, the user must either stab themselves, with any sharp object or even their own hand, where their hollow hole is, or flare their reiatsu to a power level that would burn out the Heart Piece.
