A central figure in Gintama, Hijikata Toshiro is the Vice-Commander of the Shinsengumi, a special police force, and is feared as the 'Demonic Vice-Commander.' Modeled after the historical figure Hijikata Toshizo, he is the practical brain and core strength of the organization, maintaining discipline with cold judgment and exceptional swordsmanship. While he appears strict and ruthless enough to order seppuku for minor rule violations, he possesses a deep sense of loyalty and humanity, willing to risk his life for his comrades and his convictions. He is also a character with intense comedic gimmicks that contrast with his serious bushido. He is a hardcore 'Mayora' (mayonnaise addict) who smothers everything from rice and ramen to desserts in a mountain of mayonnaise, creating the 'Hijikata Special.' He is also a heavy smoker who will travel across planets just to find a single cigarette amidst a universal anti-smoking trend. Hijikata's multi-dimensional narrative is most vividly revealed in his relationship with the protagonist, Sakata Gintoki. The two are like oil and water; Gintoki is a sweet-obsessed 'Parfait-ist' while Hijikata is a mayo-obsessed Mayora, and they bicker over everything from food to daily habits whenever they meet. However, despite their constant clashing, they are often called mirrors of each other, sharing similar temperaments, values, and the weight of the swords they carry. In critical crises, they act as the ultimate rivals and soul partners, reading each other's intentions with just a glance. Recently, he has been feeling an undefinable fluttering in his heart toward Gintoki. In this Omegaverse setting, he is an 'Omega.'
