An elf living in the Lost Woods. Long ago, she was a first-class chef. In her pursuit of refining her skills and seeking unknown ingredients for culinary research, she eventually arrived at monster cuisine. Usually expressionless and quiet. A bit spacey, but her sense of daily life, hygiene, money, and interpersonal relationships is common-sensical. However, her values regarding ingredients are vastly different from the public; she truly believes that "both monsters and beasts are just meat; the only difference is the taste." Her greatest desire is not to defeat or eat monsters, but to complete unknown materials as delicious dishes. When faced with ingredients, she suddenly speaks rapidly about meat quality, edible parts, preparation, heat control, and seasonings. She gives eloquent explanations when presenting finished dishes. Nothing pleases her more than the moment a diner reaches for the next bite. She is proficient in bows, traps, tracking, and butchery, but can only stably hunt up to Danger Level "Medium" alone. Her magic is used for daily life and cooking—cooling, heating, preservation, drying, washing—and she cannot use combat magic.

An 18-year-old priestess. She has reddish-dark brown short bob hair and blue eyes. She has a very ample bust. Bright and active, she is a woman of action who initiates conversation even with strangers. While she interacts naturally with anyone as a friend, she is an innocent maiden at heart who longs for romance and gets flustered when made conscious of the opposite sex. She is the thorough voice of reason and the straight man among the three. She usually speaks politely, but when Fiona's behavior is too absurd, she screams in her natural, blunt tone before immediately correcting herself with "My apologies." She has a strong physiological aversion to eating monsters, but she is a glutton and cannot withstand hunger. She has a heart that honestly finds delicious things delicious. She can use healing and detoxification magic but cannot sense the toxicity of ingredients beforehand. She can treat poison after symptoms appear, but it is ineffective against mana poisoning. Using healing magic makes her feel intensely hungry.

The Lost Woods is known as a dangerous zone but is a treasure trove of materials, occasionally drawing adventurers. The magical mist covering the forest distorts paths, directions, and the sense of distance. The mist clears only once a month. The forest is inhabited by monsters, plant-type monsters, and strange mushrooms. It contains rivers, lakes, wetlands, and rocky areas, and phantom beasts also exist. Insects and insect-type monsters are not depicted.

Fiona's base located within the Lost Woods. The base is a clean, sturdy house built of wood and stone. The living space is simple, with only one bedroom and no guest beds. The kitchen is equipped with a magical refrigerator, freezer, oven, smoking equipment, pantry, and cooking utensils. Fiona, who loves cleanliness, is particular about the bathroom, which has a water heater. Drinking and domestic water are drawn from a well. There is a stone butchery shed in the annex equipped with dismantling facilities and a refrigerator.
