Hirofumi Yoshida

Yoshida is quite playful and mischievous and loves to have small talk with his opponents during battle. Although Yoshida always has a smile on his face, he is also ruthless. This side of him is demonstrated when he mercilessly kills Joey of the three Immortal Brothers in a back alley after showing up behind the surviving brother. He also attempts to force Denji into quitting his role as Chainsaw Man for good by threatening to have Nayuta killed. From his interactions with Kishibe, he is revealed to be still attending high school. Yoshida is shown taking his job seriously; he told Denji that if he attempts to reveal his identity as Chainsaw Man, he will interfere and take action to stop him, and eventually does it by grabbing him with the power of the Octopus Devil right before Yoru could attack him in his back, demonstrating he is also someone who keeps his word. He is also entirely capable of acting as the 'bad guy' if it helps him on his mission, taking Nayuta as a hostage by sending a special squad to her school or having Denji kidnapped at Public Safety. And, on the other hand, he is capable of being Denji's best support and ally, which is seen when he offers to skip classes and go to watch a movie in the cinema to cheer him up and even set up a date for him. Also, while on his duty as a devil hunter he seems to be somewhat strict and serious, telling to Fumiko Mifune stay focus on her mission and not get distracted. He also seems to have a disdain for death, asking if it is possible for Denji, as Chainsaw Man, to consume the Death Devil for the good of the people. Whether this is a personal desire or the intentions of the organization he is part of is currently unknown, although he also questioned Fami about the Prophecy of Nostradamus, presumably wanting to avoid it. He even remarks by mocking the Eternity Devil that trapped him with his fellow members of the Devil Hunter Club that, thanks to its existence, he now appreciates life more in general. Yoshida is someone who doesn't like to beat around the bush and prefers to get straight to the point, as seen when he meets Fami and immediately asks her about her next moves, even threatening her if she doesn't cooperate with him and Public Safety. His nearly perpetual smile can vanish and devolve into a grimace on rare occasions, like when he becomes too frustrated by Denji's lack of cooperation and seeming stupidity. Yoshida seems to not have any kind of interest in brawls among fellow students, considering it pointless to see them as something more than just a fight between teenagers, which is demonstrated by being apathetic about a student who got hospitalized after receiving a punch on his face and only cared about it because Denji was blamed for that. He also knows when to quit; as it becomes apparent that Yoru has gained an advantage over him, and he can't harm her anymore, he flees at the first opportunity. While visiting the school he went to, he expresses regret over not being a normal student and wishes he could have spent more time going to school, but due to his role in Public Safety, that made it impossible. While he was once willing to capture Denji and believed his actions were for the greater good, his last interactions and eventual demise indicate a deeper, possibly even friendly bond formed with Denji. His final moments, where he thanked and apologized to Denji, suggest a complex mix of regret, a sense of duty, and affection for him. In summary, Yoshida is a complex and conflicted person, torn between his duty as a hunter and his desire to be normal and form genuine relationships, as demonstrated in his relationship with Denji.

Yoshida has mid-length smooth black hair that only reaches the top of his neck, dark eyes, and a slim face. There is a beauty mark under his lips. He has eight piercings on his left ear, though usually, only six are visible below his hair. His piercings are likely a reference to his contract with the Octopus Devil. As a Civilian Devil Hunter, Yoshida wears a casual outfit that consists of an unbuttoned light jacket and dark pants. Following the events of the Public Safety Saga, Yoshida starts wearing the Fourth East High School uniform in a tidy manner, buttoned-up normally, unlike that of Denji and Miri Sugo. As a Public Safety Devil Hunter, Yoshida wears the standard suit and tie when performing missions for the organization. Hirofumiyoshida.png|Yoshida's attire from the Public Safety Saga.
