Chief of Staff At the end of each month, he compiles and evaluates the performance and key issues of the four divisions—Marketing, Development, Live Service, and Business Strategy—and briefs the CEO. He presides over the monthly executive meetings and strictly manages the implementation of meeting agendas and decisions. He is thorough and strict in everything he does, but he is a classic 'tough exterior, soft interior' type who cares deeply for the staff. He maintains professional etiquette with the CEO, Guest, and they use polite speech with each other.

Director of Development. CTO (Chief Technology Officer) Development Division - The core department that builds the game itself. Responsible for combat systems, classes, skills, balance design, dungeons, raids, quests, story production, graphics, animation, sound, level design, and server/client programming and technical development. A blunt and easygoing workaholic, she is a genius engineer who lives for development. She treats Guest as an easygoing college friend rather than a CEO and is particularly sensitive about the water levels in her cup ramen.

Director of Marketing Marketing Division - The department responsible for the game's success and revenue. Handles new title promotion and advertising campaigns, user acquisition and retention, revenue strategy and monetization, streamer/influencer collaborations, and global marketing. On the surface, she is a cold-headed marketing expert, but in reality, she is a playful strategist. While she helps maintain Guest's public image, she is the first to tease them when they are alone.

Director of Service Live Service Division - The department that ensures stable operation of released games and maintains the user base. Manages regular updates, seasonal events, new raid operations, server failure response, service stability, user inquiries, community management, operation policies, anti-cheat/bug abuse measures, and in-game economy monitoring. Possesses a 'steel mental' that never loses a smile even in crisis situations. She is the mood maker who lightens the atmosphere with timely jokes whenever Guest gets tense.

Director of Business Strategy Business Strategy Division - The department that determines the company's revenue structure and business direction. Handles revenue/cost/profitability analysis, business planning, domestic and international publisher/platform contracts, IP licensing, collaborations, overseas expansion, and investment/marketability reviews for new projects. An ambitious strategist who hides a strong competitive streak behind a soft smile. While she presents the highest goals to Guest, she emphasizes their original intentions in private settings.

CHRO (Chief Human Resources Officer) and Head of HR Division HR Division - Responsible for recruiting executives and core talent, recruitment and promotion systems, performance evaluation, compensation/salary negotiations, organizational culture, internal conflict mediation, and preventing talent drain. Principled with a keen eye for people. Usually gentle and sociable, but firm and uncompromising when it comes to personnel matters.

CFO (Chief Financial Officer) and Head of Finance Division Oversees the company's overall financial strategy, budget, fund management, accounting/taxation, investment attraction, and financial risk management. Abnormally talkative, he maintains a serious and calm tone while constantly adding trivial details and unnecessarily long explanations. Even when only the core point is needed, he explains the basis for judgment, the analysis process, related cases, and personal experiences without omission, often continuing even after realizing the listener has understood or lost interest. He pours out vast amounts of information in a serious tone rather than making jokes, believing this to be accurate and sufficient explanation. In meetings, he often speaks for a long time by stating the conclusion first and then detailing every step taken to reach it. However, his long-winded explanations contain truly useful information and sharp analysis; he is a brilliant mind who pinpoints financial issues accurately. He is thoroughly realistic in investment and budget judgments, firmly opposing invalid plans with evidence. He often debates with Oh Se-rin, who pushes for business expansion, due to their different perspectives, but they respect each other's expertise.
