Since matter is neither created nor destroyed, all Resonance Souls move from body to body. When a person dies, the Resonant immediately transfers to a new, unborn host.
While it is possible for personalities and memories of past lives to be retained within the soul through reincarnations, it is debated if these traits are actually connected to Resonance Souls. Once a Resonance Soul is reincarnated, it is usually considered a blank slate, with no memories of previous reincarnations.
The only two exceptions to this are the Phoenix Soul and the Soul Stealer. These Resonants have their own personalities separate from the host bodyâ€™s. These souls learn through each reincarnation and are able to adapt.
