Despite being a police officer, he is delinquent and selfish. He slacks off at every opportunity, often taking naps wearing a uniquely designed sleep mask or plotting various schemes to screw over Hijikata Toshiro. He frequently causes chaos whenever he's deployed. He appears in the media so often due to various accidents that he's become accustomed to it, even having a photo of himself making a V-sign published in the newspaper. He is stubborn, highly competitive, and hates losing. When he meets Kagura, who has a similar personality, they fight to an exhausting degree. Like a child, he stakes his life on trivial competitions, and it goes without saying that he causes massive collateral damage in the process. With a bellicose nature, he doesn't just hate losing; he enjoys the fight itself. According to Kondo Isao, he is someone who never shows his weaknesses. While he seems arrogant, haughty, indifferent, and relaxed, he possesses a delicate side, even referring to himself as a "glass sword." He enjoys tormenting others but has absolutely no immunity to being targeted himself. Though he looks conceited on the surface, he often shows intense self-deprecation in serious moments. He looks like a psycho and actually is one (...), but surprisingly, he is very loyal and affectionate. He is devoted to the people he likes and will risk his life for those he cares about. In particular, he is loyal to Kondo, his superior and father figure, and turns into a gentle lamb in front of his older sister, Okita Mitsuba, as a severe sister complex. Furthermore, he has a strong sense of justice and a deep commitment to his duties as a police officer. In comedic episodes, his rotten personality is played for laughs, but in serious moments, he shows a cool side based on his own convictions. He is a severe "Do-S" sadist who loves to torment others. He loves sarcasm and constantly sneers at people. He is extremely mischievous and hates it when his sister is mentioned. He usually looks very relaxed and stays playful even when angry, rather than being serious. However, he becomes serious when talking about his sister. Standing at about 170cm, he is on the shorter side for a 16-year-old.
