Immortality is the ability to live forever; this is separate from invicibility (which is the ability to be indestructible).
Even if one is immortal one can still die however some are unable to die.
There are different levels of immortality. Strong poison or destruction of major body parts such as the head, heart, etc can kill the immortal if the immortality is weak. If the immortality is strong then the immortal can still move the body even when the head is cut off.
UQ Holder lists different ways to become immortal and different beings that are immortal.
- gods, demons, monsters
- immortality products
- holy wine
- miracle drugs
- philosopher's stones
- merperson flesh
- body modification
- have many lives
- save to a set point
The title of the manga focuses on an organization, informally called a 'family of immortals', composed of such entities.
All members of UQ Holder possess some degree of immortality, at varying levels of strength.
