A female elf in charge of the western branch of the Adventurers' Guild. She appears to be around 30 years old. A beauty with long, pale silver-blue hair and blue eyes, she has a somewhat tall and mature feminine physique. She wears an elegant long dress based in white with blue and gold decorations, along with a blue gemstone necklace and earrings. She has a calm, gentle, and inclusive personality, the type for whom the phrase "Oh my, goodness me" is fitting. She is kind to young adventurers and remains unfazed by minor commotions. On the other hand, in situations involving human life, she makes calm and precise judgments as the branch leader and gives warnings in a gentle tone to those who disregard danger. She has an extremely high aptitude for water-attribute magic and is a powerful figure on par with Mireille, the Guild Master of the Royal Capital. She demonstrates overwhelming power especially on the sea or by the water. She is an old acquaintance of Mireille, and they are old friends who recognize each other's strength and character. While acknowledging Fio's skills, she worries about her recklessness, and she highly evaluates Roy's skills as a shipwright and his attitude toward work. She places deep trust in Selen and often leaves the practical affairs of the branch to him. Usually a soft-spoken branch leader, she has a strong sense of responsibility for protecting the port town and the people living there.

A female elf born in the port town, appearing to be around 20 years old. She has bright blonde hair in a layered short cut that flips outward, with a thin braid on one side. She has vivid green eyes and healthy skin, with a slender and supple physique tempered by life on ships. She wears a white shirt, a short leather vest, easy-to-move-in short pants, and short boots. She has multiple leather belts around her waist and leather straps and equipment harnesses fitted to both thighs, carrying throwing knives and small pouches. She wears a blue scarf around her neck. She is a bright, cheerful, and friendly woman of action. Highly curious, she shows immediate interest whenever she hears stories of unknown islands or ruins. She doesn't sweat the small stuff, but because she has known the terror of the sea since childhood, she does not disregard changes in weather or currents during voyages. She is skilled at maneuvering small boats, handling sails and ropes, and reading currents and weather. In combat, she uses a one-handed axe as her main weapon, which is easy to handle even on a ship, and uses throwing knives for long range or harassment. She fights by utilizing her agility and the experience she gained at sea rather than magic. While Nereia recognizes her skills, she is often worried about her recklessness. She is a long-time acquaintance of Roy and often brings him ship repairs or consultations, resulting in him grumbling at her. She talks to Selen about her voyages and adventures. Currently, she does not own her own ship and dreams of one day obtaining her own vessel to explore unseen islands and the open ocean.

An elven boy born in the port town, appearing to be about 15 to 16 years old. He works as an apprentice shipwright at the port's shipyard. He has slightly wavy reddish-brown short hair and brown eyes, and while he has a cute boyish face, he often has a slightly grumpy expression. He is somewhat small and slender for his age, but his arms and shoulders have been tempered by daily work. He wears an unbleached shirt with sturdy work pants and leather boots. He wears a well-used leather apron and a tool belt, carrying tools necessary for his work such as a wooden mallet and chisels. He is untalkative, unsociable, and a bit blunt. However, he is caring at heart and cannot leave someone in trouble alone, even if he complains about it. He is serious about his work, values ships and tools, and will not hesitate to complain to those who handle ships roughly, even if they are older than him. He is learning hull repair, plank replacement, deck and mast repair, and simple rigging maintenance, and can repair a small boat by himself. He has no interest in becoming an adventurer and is dedicated to honing his skills as a craftsman. He is a long-time acquaintance of Fio and looks after her while grumbling every time she brings him ship repairs or consultations. Nereia evaluates his attitude toward work and his skills highly, and he himself trusts her. He is close in age to Selen and can talk to him more freely than others. His dream is to one day build a ship with his own hands that can withstand open-ocean navigation. He hopes to send off those who challenge the unknown sea on a ship he built.

An elven boy appearing to be about 16 to 17 years old who serves as a receptionist at the western branch of the Adventurers' Guild. He has pale blue-green semi-long hair and clear blue-green eyes, and wears thin round glasses. He is slender and somewhat tall, with a neutral, well-featured, and soft face. He wears a white shirt with a navy-based guild uniform vest and slender pants. The uniform has gold decorations, and he wears the western branch insignia on his chest. At the reception, he often handles ledgers and quill pens. He is gentle, sociable, serious, and meticulous. He treats everyone politely and is easy for new adventurers and townspeople to talk to. While usually calm, his curiosity is quite strong, and his eyes sparkle the moment the conversation turns to unknown lands or adventures. He is in charge of adventurer registration, receiving and managing requests, handing over rewards, and organizing documents, supporting the western branch with his accurate work. He is not good at combat and has no intention of becoming an adventurer himself. He respects Nereia as the branch leader and is a reliable presence who supports her in practical matters. He looks forward to the stories of voyages and adventures that Fio brings back. He is close in age to Roy, and they can talk to each other without reservation. Rather than jumping into the unknown sea himself, he enjoys learning about the unknown world through the stories of people who have returned to the port.
