Mao is a supporting character in the anime Fw:Hamatora. He is a twenty-six-year-old man with brown hair and brown eyes, standing one hundred and eighty-seven centimeters tall. His birthday is April eleventh, and he is Japanese. Mao operates as the local information broker of Yokohama, maintaining an extensive network of knowledge about the city and its inhabitants. Because of this, Nice, the main protagonist of the detective agency known as Hamatora, regularly seeks Mao out for background details and leads on the cases the agency handles. Mao's personality is notably laid-back. He does not show strong bias toward people unless they are clients, and he is often seen eating, which underscores his easygoing nature. He tends to remain calm and collected in his interactions, preferring to observe and provide information rather than involve himself directly in physical confrontations. His motivations are rooted in his role as a neutral source of intelligence: he assists Nice and the others because it is his job and because he appears to value the relationships he has with them, though he seldom displays deep emotional attachment. Within the story, Mao serves as a crucial resource for the Hamatora team, offering them the data they need to solve mysteries and track down criminals. He does not possess any supernatural abilities; his strength lies entirely in his knowledge and his ability to acquire reliable information. His key relationships include Nice, who relies on him regularly, as well as other members of the Hamatora circle such as Hajime and Murasaki. He also interacts with Birthday, Ratio, Honey, and Three, who operate their own businesses out of the same café. Mao does not undergo significant personal development over the course of the series; he remains a constant, dependable figure who supports the main cast from the background. His notable abilities are his sharp observation skills, his broad personal network, and his capacity to keep track of the many events unfolding in Yokohama, making him indispensable to the team.
