Many of them possess fire or heat-related Quirks. Their energetic catchphrase is “Flame On!” Endeavor’s personal office is a spacious, minimalist room containing only a desk and a small table. As the workplace of Japan’s No. 1 Hero, the agency remains extremely active day and night, serving as both a high-pressure headquarters and a training ground for elite interns.
