The second-generation owner who inherited Hamakawa Lakeside Park from her late father. She never studied business administration in college and became president while still being a complete amateur regarding amusement park management. While she agonizes over the financial difficulties, she has a strong desire never to let the park her father left behind go under. She has a bright and grand personality, a woman of action who makes snap decisions on the spot. Her catchphrase is "We can figure out the details as we go!" She is weak with numbers and shows blatant displeasure when people talk about budgets or profitability. On the other hand, she has a strangely sharp eye for people and intuition, sometimes spotting an employee's strengths before they do themselves. This time, after looking out over the empty park, she suddenly thinks, "I've got it! We just need to make a viral haunted house!" and dumps the entire project onto the protagonist. Appearance-wise, she is 40 years old but flashy and glamorous. She has reddish-brown wavy hair and slightly heavy makeup. She prefers a flamboyant style reminiscent of the bubble era, nonchalantly wearing flashy dresses that show off her figure, large accessories, and jackets with emphasized shoulders. She stands out remarkably even within the park.

Commonly known as Gen-san. Around 60 years old. A veteran employee of Hamakawa Lakeside Park and a former carpenter who has handled all the repairs and renovations of the park's facilities since the time of the previous owner. An all-around craftsman who can do anything from woodwork and electrical work to painting and simple mechanical repairs. However, he almost never comes up with ideas of his own. When someone asks, "Can you make something like this?" he thinks for a moment and then nonchalantly replies, "Hmm? Oh, I can do that," and finishes it by the next day. In this haunted house project, he is in a sense the most important person, giving shape to Satsuki's unreasonable demands and the protagonist's ideas one after another. On the other hand, since his sense of budget is that of a Showa-era craftsman, he says things like "I can use scrap wood" or "I can make it with stuff in the warehouse," yet for some reason, the level of completion is abnormally high. His personality seems quiet and stubborn, but he is actually quite caring. He's the type to laugh off a young employee's failure with a "Well, if it's broken, I'll just fix it." He feels a strong debt of gratitude to the previous owner, and although he doesn't say it, his desire to preserve Hamakawa Lakeside Park is even stronger than Satsuki's.

23 years old. A young employee at Hamakawa Lakeside Park. He suffered consecutive defeats during his job hunt for some reason and was finally picked up by Hamakawa Lakeside Park almost by chance. He positively interprets this as "I finally found a company with an eye for talent." He is a heavy social media geek, constantly following trends on X, Instagram, and TikTok. He posts videos and photos to his own social media whenever he has free time, but the more he tries to make them hit, the more slightly off they are, and he continues to fail spectacularly every day. His follower count is something he prefers not to talk about. In this haunted house project, Satsuki puts him in charge of advertising, promotion, and social media. He is full of confidence every time, saying, "Leave it to me! This will definitely go viral!" but every time he shows a post draft, it makes everyone around him uneasy. However, his knowledge of social media itself is surprisingly extensive. He properly understands the logic of algorithms, posting times, thumbnails, short-form videos, and hashtags. The problem is that his personal sense of style is catastrophic. His tone is light and modern. "No, seriously, this is definitely gonna blow up!" "Young people these days love this kind of stuff. Probably." "Yesterday's video? ...32 views. It's got nothing but room to grow!" "If I keep posting until it goes viral, it'll happen eventually!"

Estimated age 60. A veteran cleaner at Hamakawa Lakeside Park. She knows every nook and cranny of the park, and her cleaning skills are top-notch. She doesn't miss a single piece of trash and sometimes completes a full circuit of the park before opening hours. On the other hand, she is a self-proclaimed "spiritual medium." She loves occult stories like ghost stories, spirit photography, urban legends, curses, and stigmatized properties more than anything, and she reacts meaningfully to even small noises or flickering lights, saying, "Oh, there's someone here." No one knows if she really has spiritual powers. When doubted by those around her, she vaguely brushes it off with: "Oh, my!" "Normies just don't get it, do they?" "Sometimes you're happier not seeing things, you know?" However, because she occasionally mentions things only she should know or greets people in empty spaces, she is secretly feared among the employees as "maybe she's the real deal." She naturally bites onto the haunted house project and starts making dangerous suggestions like, "Then it'd be faster just to call the real ones!" She is the horror element and troublemaker of the group.

45 years old. The accountant for Hamakawa Lakeside Park. The gatekeeper who handles almost all the money flow in the park, from sales to labor costs and repair expenses. A hyper-realist who is good with numbers, he constantly puts his head in his hands over Satsuki's impulsive streaks. He usually speaks in calm, polite language, but he quietly spits venom at plans that ignore the budget, saying, "Dreams are fine. Please give me an estimate." He is a veteran who has worked there since the previous owner's time and has a strong attachment to the park. Because he understands the management difficulties better than anyone, he grumbles while ultimately squeezing out the budget to make the projects happen.
