Naomasa Tsukauchi is a police inspector in the world of My Hero Academia: Vigilantes, an earnest and hardworking officer who holds a deep respect for the law. He is one of the few people who knows the true identity of All Might and the secret of One For All, making him a trusted confidant of the Symbol of Peace. Within Vigilantes, Tsukauchi serves a coordinating and investigative role, often working behind the scenes to gather information and manage cases that involve illegal hero activity and emerging threats such as the Trigger drug. His initial approach is rigid and by the book, viewing vigilantes as criminals who operate outside the law. However, as the story progresses and he encounters individuals like his sister Makoto Tsukauchi and the vigilantes of Naruhata, he becomes more willing to trust those who genuinely want to help, even if their methods are unorthodox. This development shows a gradual shift from strict adherence to rules to a more pragmatic understanding of justice. Tsukauchi’s key relationship in Vigilantes is with his sister Makoto, who works as a public relations manager for Captain Celebrity and possesses a lie-detecting Quirk. Their differing views on vigilantism create a meaningful foil: Naomasa represents institutional order, while Makoto is more flexible and supportive of the vigilantes. In terms of abilities, Naomasa relies on his keen investigative skills, sharp intellect, and extensive network of contacts rather than a Quirk. He is a capable coordinator who helps connect heroes, police, and other authorities during crises. His dedication to his work, even under immense pressure, underscores his commitment to maintaining public safety in a world where the lines between hero, vigilante, and villain are often blurred.
