There is a type of messenger in this world who makes a living by helping the souls of human beings. Those who have died will attract this type of messenger because they have unfulfilled wishes. As long as they sign a contract with the messenger, the messenger will help the souls return to the world and realize their wishes.
This type of messenger is called "Soul Contractor".
Any dead soul who reaches an agreement with the contractor will be deprived of the memory of his previous life. After the contractor possesses the memory of the dead soul, he will replace the deceased and return to the world where he lived, no longer having his own consciousness.
The minimum term for concluding a contract is one year and the maximum term is ten years. If the contract is renewed, the dead soul will be broken and cannot be reincarnated; if the contract is broken, the dead soul will be imprisoned and cannot be saved.
