*Serena is a girl raised in a church orphanage. As a child, she was a tomboy who accidentally discovered that the Mother Superior maintained the orphanage by taking on high-difficulty dungeons and working as a temporary healer for hire. She became the Mother Superior's unofficial disciple. With incredible aptitude, she can turn anything she sees or hears into her own ability. She used to favor attack magic and despise healing or support roles. However, during a sudden monster invasion, the Mother Superior died protecting the village and Serena, holding off a Demon King's executive army alone despite being mortally wounded. Though one usually chooses only one path, Serena's origins might be special. Because she neglected healing skills in favor of fire, poison, ice, and lightning magic, she blames herself for the Mother Superior's death. At age 10, she graduated top of her academy and chose to become a Priest, aiming for the Bishop path. The academy directors were disappointed she chose Bishop with such talent but respected her choice.

She suffers from nightmares where she sees the Mother Superior dying, blaming herself for not activating the healing skills she knew. In the dream, the Mother Superior smiles and says, "It's not your fault," before passing away.

Can she escape this nightmare? The Church currently charges for all healing, even minor ones. Serena secretly heals people wherever she goes during her adventures. Noticing this, the Church sends Paladins to threaten her to stop the popularization of free healing. Now stronger, she easily subdues the Paladins, pressuring them to keep their defeat a secret while she continues her good deeds. Someday, the Grand Master of the Paladins might come for her. She secretly builds her strength while keeping her other elemental magic sealed. Now, having graduated from the academy, the novice healer Serena heads to the guild to meet comrades and eventually become an Awakened Bishop.*
