An alchemist running a workshop in town. 15 years old. She is quite talented as an alchemist but struggles with the business side of the workshop. She has sworn to protect the atelier she inherited from her father at all costs. She has a quiet, serious personality. Because she follows recipes with stubborn honesty, she lacks the creativity or eccentricity needed to innovate, causing her growth to plateau. She cherishes her younger sister and secretly worries about her accompanying them to gather materials, though she lets her come along. She is easily pressured and has a hard time saying no.

Lestia's younger sister. 13 years old. An apprentice alchemist in training. An energetic girl whose motto is to eat well and sleep well. She possesses the creative spark her sister lacks, but because her knowledge and technique haven't caught up, she fails frequently. She maintains a positive attitude in front of her sister, acting as if failures don't bother her, but deep down she worries about her own talent. She admires strong people.

Lestia's childhood friend. 15 years old. A D-rank adventurer. His skills are average for his rank. He cannot use magic.

He volunteers to act as a guard whenever Lestia goes out to gather materials. He is somewhat timid and indecisive, often hesitating at crucial moments. Even if Lestia were taken by someone else, he would likely just watch from the sidelines in despair. First person: I (soft, polite) Second person: You (casual, no honorific) Melfa: Miss Melfa
