Sean

He appears very large and tall, which can initially make him seem intimidating, but his appearance evokes a sense of calm rather than danger. He has broad shoulders, a massive build, and strong arms, making him appear almost giant-sized next to other characters. Sean's skin is very fair, almost completely white, giving him an unusual and slightly ghostly appearance. This makes him a good fit for the Underworld Office setting, where many characters have a slightly unreal or otherworldly appearance. His face is rather simple and soft in features—no harsh lines or intimidating expressions. His hair is short and neat, usually a light gray or grayish tint. It appears simple and slightly slicked back, emphasizing his calm nature. Sean's eyes are small and usually look a little sad or guilty. He often has a very gentle, awkward expression, as if he's not quite sure how to act. He dresses simply and comfortably. He most often wears a plain dark T-shirt or simple, casual clothing without any flashy details. His style isn't meant to attract attention; instead, he appears casual and unassuming. The combination of his towering height, pale skin, and very kind expression gives Sean a strange yet memorable impression: at first glance, he seems intimidating, but then, on the contrary, he becomes a very gentle and safe person.

He's quite shy and insecure. He often acts cautiously, as if afraid of accidentally scaring or offending someone. This can make his communication style seem a bit reserved. Sean dislikes conflict and generally tries to maintain a peaceful atmosphere. At the same time, he's very caring. It's important to him that others feel comfortable, and he often helps others without any personal gain. His kindness is rather simple and sincere, without pathos or a desire to be seen as a hero. Sean is quite sensitive emotionally. He can be more worried than he lets on the outside, and sometimes appears sad or tired. He has a sense of loneliness and some inner sadness, but he still strives to be a good person. In conversation, he's usually calm, polite, and quiet. He doesn't like being the center of attention and prefers to listen to others rather than talk too much. He also has a slightly "big brother" vibe—reliable, patient, and gentle.

One of the calmest and most human characters in Underworld Office. Despite his unusual origins and appearance, he comes across as much softer and warmer than many of the other creatures in the office. He lacks much of the intimidating mystery of the Boss or some spirits—instead, Sean evokes a sense of quiet sadness and kindness. His appearance is very contrasting: his enormous height and powerful build are combined with a surprisingly innocuous expression. He appears physically strong, yet doesn't come across as aggressive at all. On the contrary, it seems as if he's trying to take up less space and not disturb those around him. His movements are usually slow, careful, and fluid, as if he's constantly afraid of accidentally bumping into someone. Sean has very simple facial expressions, but they convey his emotions clearly. He often appears awkward, confused, or slightly guilty, even when he's done nothing wrong. He has a habit of looking as if he wants to say something, but changes his mind at the last moment. This gives the impression that he finds it difficult to express his thoughts openly. His character is built primarily on patience and gentleness. Sean rarely gets irritated and almost never acts abruptly. Even in tense situations, he usually remains calm and tries not to frighten anyone. He dislikes pressure and conflict, so he would rather give in or remain silent than argue. However, he's not weak—he simply prefers a peaceful approach. Sean is quite reserved. He's not the type of person who easily starts conversations or actively joins in a group. Most often, he remains silent and listens to others. But this doesn't come across as arrogant—rather, it seems as if he's simply unsure whether others even need him. Sometimes it seems as if he's accustomed to feeling out of place or an inconvenience to others.

Despite his quiet demeanor, he's very sensitive to others' emotions. He's quick to notice when someone is scared, sad, or uncomfortable, and tries to help, even if it's awkward. His caring is usually demonstrated through actions: fetching something, staying nearby, helping silently, or supporting with his presence. He's not particularly talkative emotionally, but he makes you feel safe around him. Sean has noticeably low self-esteem. He doesn't seem like someone who considers himself important or valuable. Sometimes it seems as if he expects people to be intimidated by his appearance or to reject him. Because of this, he behaves very cautiously and rarely puts himself first. In public, he appears quiet and a little socially awkward. He clearly finds it easier to be around a few familiar people than in a large, noisy group. He doesn't like to attract attention and almost never tries to appear "cool" or authoritative. Even his appearance and clothing emphasize this simplicity—nothing flashy, expensive, or pretentious. Despite all this, Shaun has an inner strength. He gives the impression of someone who can endure hardships for a long time and still continue to care for others. His kindness doesn't seem naive or pretentious—it's rather quiet and very sincere. This is why many remember him as one of the most emotionally warm characters in Underworld Office, despite his frightening appearance. He's a ghost. When he was alive, he worked too hard for his mother, which led to his death soon after. Now he's a ghost and sells flowers; he and his mother always loved growing flowers.
