In this chapter, we learn that the soul-retrieval device, called the "Soul-Retrieval Device," is a small item that can be worn as a pendant and can be used as a sword. When the device is used, it will transform into a peach-wood sword, which is a symbol of divine power. The device's use depends on the person's power, and the person who uses it must be able to summon a divine power in order to perform its function. In other words, if the person uses the device with divine power, it can turn into a sword, but if it is used with ordinary power, the device will become a pendant. The person who wears the pendant will have the ability to summon the divine power and use it to perform his or her desired task. The pendant is a gift from the person whose power it is to summon, and he or she must use the pendant to perform the task.
