Once upon a time, there was a witch named Ireina. She travels alone, unbound by anyone and free from any constraints. Along her journey, she encounters a variety of unique individuals... A group hunting elves and dark elves wandering in search of companions. A wealthy traveling party striving to bring back a daughter's smile. The "Witch of Coal" and her sister, who are conducting undercover investigations. Sisters searching for a new hometown. A good-for-nothing sorceress aiming for a publicity stunt. And a young exorcist who arrives in a certain village... What will be written in Ireina's diary about these encounters and events? "Well, if it's in my hands, it's a piece of cake."
