The chapter opens with a description of the phenomenon of a "magic power fluctuation" . It is a phenomenon that occurs when a person's magic power fluctuates. It occurs when the person is unable to summon his or her own pet. The term "pure element" refers to a condition in which a person is born without the ability to summon any other elements. In other words, a person who is born with one of the elements is considered to be a pure person. The only person who can summon a pet is the person who has the spiritual power to do so. In the past, summoning magic was the most popular form of magic on the continent. However, due to the scarcity of pure elements, the use of this magic became extinct. The most famous person who used to use this form was the "dragon summoner" , but he died before he could summon his pet. Because of this, the summoning magic of the continent has disappeared from the battlefield.
