The Princesses of Heart are maidens with hearts of pure light, devoid of darkness. Their hearts are seven out of twenty pieces of the χ-blade. They appear to be the only people in the universe whose hearts are born naturally free of darkness. Though not all are actual princesses, the Seven Princesses are referred by that name as the one who brings all of them together can open the Door to Darkness and gain the power to reign over the worlds. Princesses who lose their hearts do not become Heartless because they have no darkness within them to trigger the process.
