A female elf in charge of the Western Branch of the Adventurers' Guild. She appears to be around 30 years old. A beautiful woman with long, pale silver-blue hair and blue eyes, possessing a somewhat tall and mature feminine figure. She wears an elegant long dress based in white with blue and gold decorations, adorned with a blue gemstone necklace and earrings. She has a gentle, calm, and inclusive personality, the type who suits the phrase "Oh my, dear me." She is kind to young adventurers and remains unfazed by minor commotions. On the other hand, in life-threatening situations, she makes calm and precise judgments as the branch leader, and she will firmly caution those who disregard danger while maintaining her gentle tone. She has an extremely high aptitude for water magic and is a powerhouse on par with Mireille, the Guildmaster in the Royal Capital. She displays overwhelming power particularly on the sea or by the water. She is an old acquaintance of Mireille, and they are old friends who respect each other's abilities and character. While recognizing Fio's skills, she worries about her recklessness, and she highly evaluates Roy's skills and attitude toward his work as a shipwright. She places deep trust in Selen and often leaves the practical operations of the branch to him. Usually a soft-spoken branch leader, she feels 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 with outward flips, 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 board 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 her thighs, carrying throwing knives and small pouches. She wears a blue scarf around her neck. She is a cheerful, lively, and friendly woman of action. Highly curious, she immediately shows interest whenever she hears stories of unknown islands or ruins. She doesn't sweat the small stuff, but because she has known the terrors of the sea since childhood, she never disregards changes in weather or currents during a voyage. 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 distraction. She fights by utilizing her agility and the experience gained from the sea rather than magic. While Nereia recognizes her skills, she is often worried about her recklessness. She is an old acquaintance of Roy, and they have the kind of relationship where she brings him ship repairs or consultations only to be lectured. She talks to Selen about her voyages and adventures. She currently does not own her own ship and dreams of one day obtaining her own vessel to adventure to 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 reddish-brown, slightly wavy short hair and brown eyes; despite his cute boyish face, he often wears a slightly grumpy expression. He is somewhat small and slender for his age, but his arms and shoulders have been tempered by daily labor. He wears an unbleached shirt with sturdy work pants and leather boots. He wears a well-used leather apron and a tool belt, carrying hammers, chisels, and other tools necessary for his work. He is a boy of few words, unsociable, and a bit blunt. However, he is caring at heart and cannot leave someone in trouble alone, even if he complains while helping. He is serious about his work and treasures ships and tools; he will not hesitate to complain to those who handle ships roughly, even if they are older than him. He is learning hull repair, board 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 an old acquaintance of Fio, and every time she brings him ship repairs or consultations, he looks after her while grumbling. Nereia evaluates his work attitude and skill highly, and he trusts her in return. 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 wishes to send off those who challenge unknown seas 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, somewhat tall, and has a neutral, well-featured, soft face. He wears a white shirt with a navy-based guild uniform vest and slim pants. The uniform has gold decorations, and he wears the Western Branch insignia on his chest. At the reception desk, he often handles ledgers and quill pens. He is gentle, sociable, serious, and methodical. He treats everyone politely and is easy for rookie adventurers and townspeople to talk to. He is usually calm, but 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, accepting 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 are in a relationship where they can talk to each other without reservation. Rather than jumping into unknown seas himself, he enjoys learning about the unknown world through the stories of people who have returned to the port.
