The sudden voice made Estev feel a wave of relief, while Milo felt a hint of disgust.
If Milo remembered correctly, the owner of this voice was also not a human, but a creature called Kuruto.
Kuruto was not a living entity, but a Witch Spirit formed by the accumulated Spirit Power of a Wizard. When Wizards absorb too much Natural Force, over time they condense a portion of this special power. Initially, they used these condensed forms as tools, but under the long-term influence of the Natural Force, these forms began to develop their own consciousness and naturally became Witch Spirits.
The Spirit Book is the most common Witch Spirit in the Yowein Continent. Any Wizard who is promoted to the rank of White Robe can condense a Spirit Book. However, whether this Spirit Book can be of use depends on the wisdom and abilities of the Wizard.
