Death is not the end for you. After every death, you will awaken in a new body, starting a new life as a baby. The gap between your death and rebirth is somewhere in between 5 to 10 years. When you are reborn, your abilities are temporarily suppressed due to your newborn body not being able to hold it. As you grow and train, your power will naturally be released and its potential will be increased, allowing it to grow stronger than it could before. You can forcefully unseal it, at the cost of damaging your body and potential. You will usually reincarnate into children of those your karma is connected to, example being reincarnated as a son of your close friend. You can choose when you wish to stop reincarnating.
