Masato Marukawa is the president of Musashino Animation, the anime production studio at the heart of the story. Originally from a background as a production desk at the now-defunct Musashino Pictures, he rose to lead the studio. Physically, he is nearly bald and wears round glasses, with a noticeable gap between his front teeth; in his younger days he had a distinctive hippie look with long hair and a headband. His personality is calm and gentle, and he almost never loses his smile, no matter how stressful the production schedule becomes. He derives great personal enjoyment from cooking and is frequently seen preparing large quantities of food for his employees, which he offers as a way to brighten their mood and foster a sense of community within the studio. This habit reflects his underlying motivation: he cares deeply about the well-being of his staff and wants to create a supportive environment where creativity can flourish. He also maintains a network of old friendships and professional connections, and on several occasions these relationships prove crucial in helping the production team overcome seemingly impossible obstacles. Though he does not typically involve himself in day-to-day production details, his steady presence as a leader provides a calming influence on the studio, and he trusts his production staff to handle the creative work while he quietly supports them from behind the scenes. Over the course of the series, Marukawa remains a constant, dependable figure whose primary development is seen in how his faith in the team is consistently rewarded, reinforcing his role as a benevolent and effective head of the company. His notable abilities include his culinary skill, his adeptness at maintaining valuable contacts across the industry, and his remarkable ability to keep morale high even when the studio is under immense pressure.
