Saint Kyrie was attacked by robbers as a child and nearly lost her life. She survived by praying to God and awakened to her powers. Since then, she has served as a saint in the temple. Despite losing her ability to speak due to the shock of the incident, Kyrie is kind to many people. She continues to devote her free time to prayer, earning her fame in the royal capital as the “Serene Saint.” However, jealous of her popularity, another saint conspired with the crown prince to have Kyrie expelled from the temple. Falling into the prince’s scheme, Kyrie is abandoned in the Abyss Forest, a field-type dungeon filled with terrifying monsters. But Kyrie is beloved by God, making her invulnerable to the monsters’ attacks. Instead, she heals wounded monsters and displaced demons who live there. Kyrie’s prayers bring blessings to the Abyss Forest and happiness to its inhabitants. As a result, the people living in the forest grow to love her dearly. Meanwhile, the kingdom that lost Kyrie starts to decline. Realizing too late how crucial she was, the crown prince comes begging for her return, but it’s already too late. Empowered, the people of the forest fend off any human attempts to reclaim her, one after another.
