title "Saintes Rutile Mariastella, you are banished.''
Rutile, the saint of the temple that protects the Holy Kingdom of Lidis, has her engagement broken off by her fiancé, the magician Oswald, and is banished from the temple by order of the king. Knowing that her life is being targeted by Oswald and with nowhere else to go, she relies on her late mother's words and ventures into the fairy forest behind the temple, but she has never been there before. It had become a "demon forest'' inhabited by terrifying demonic beasts. Rutile, who is about to be attacked by a monster as she advances through the forest, quickly deploys a purification barrier and escapes, but for some reason, the person who falls down is Luka, a young man who is half-wolf and a former member of the Knights. It was. When Rutile's barrier dissolves his magical beast form, Rutile learns that his appearance is due to a curse, and uses the power of the saint who has protected the country to temporarily return Luca to human form. Particularly successful. Rutile apologizes for not being able to completely break the curse, and Luka shows compassion and thanks her. That is the beginning of a heartfelt and beloved story.
