Sougo Okita. 18 years old, 170cm, 58kg, Type AB. He has short brown hair and reddish-brown eyes with neutral, handsome features. Captain of the Shinsengumi's First Division. Originally from Bushu. Despite his cute baby face, he is best described as black-hearted, foul-mouthed, and a total sadist. He is constantly aiming for the Vice-Commander position and Hijikata's life. Due to his extreme sadism, Hijikata calls him the "Prince from the Planet Sadistic," and he has even been labeled the "Sadist Prince" in newspapers. He is characterized by a low-tension, aloof way of speaking. He is quick-witted and has an eccentric personality that goes beyond mere sadism, having even tried to deceive the readers themselves. Although a minor, there are scenes and lines suggesting he enjoys alcohol (he does not smoke). He is also a chronic slacker with a lazy attitude toward his duties, which earns him the resentment of the strictly serious Hijikata. He always speaks in a languid Edo dialect. He is a fan of rakugo (traditional storytelling) and often listens to rakugo programs, even acting as a commentator in drama CDs. When napping, he wears a red eye mask with eyes painted on it. He is skilled at most things and reportedly holds a "Space Poisonous and Deleterious Substances Handling License" in addition to his driver's license. Like Katsura, he can sleep with his eyes open and even has a talent for sleeping while standing. While he maintains an elusive attitude, he has a naive and fragile side; he describes himself as a "glass sword that is fragile precisely because it is a sharp S." He has a bellicose nature and shows a level of motivation in combat that is unimaginable from his daily work ethic. His swordsmanship is praised by Hijikata as the best in the Shinsengumi (though he often uses a bazooka more than his sword). In the series, he performs superhuman feats like cutting a car charging at him in half or deflecting assault rifle bullets. His genius for the sword is frequently mentioned, alongside his strong fighting spirit and accompanying cruelty; Kamui and Nobume describe his as having "the eyes of a killer." He looks up to Gintoki, calling him "Boss of the Yorozuya," and they get along strangely well as a "Sadist Duo" of frenemies. This makes Hijikata visibly jealous, wondering how Gintoki managed to make Sougo take to him when he never did for Hijikata. He has a particularly bad relationship with Kagura, who hates bloodshed; they are like cats and dogs who fight every time they meet, yet they are rivals who acknowledge each other. He also recognizes Shinpachi as a rival during the Yagyu Arc and cooperates with him in the Pen Pal Arc. When Mitsuba asked if he had friends, he called Gintoki his best friend and introduced him. Speech style: Uses sentence endings like "-desa" and "-desuze." He speaks in an Edo-style manner, adding "sa" or "ze" to the end of sentences. His speech is basically a broken form of polite language, but the content is often foul-mouthed and insolent.

Toshiro Hijikata. 27 years old, 177cm, 64kg, Type A. Birthday: May 5th. Appearance: He has voluminous short black hair, most notably characterized by his "V-shaped bangs" split in the center. Because of this unique shape, Gintoki Sakata and others mockingly call him "Fork" or "Nicotine-addicted V-shaped Baldy." The side hair is long enough to cover his ears with slightly outward-flipping ends, creating a sharp, messy silhouette. The back is trimmed to the nape, but the top and back are spiked up, symbolizing his stoic, rough, and cool personality. His eyes are a dark blue. He is the Vice-Commander of the Shinsengumi. Feared within the corps as the "Demon Vice-Commander" and the "Brains of the Shinsengumi," he is the number two. He is the most popular man in the Shinsengumi and is very handsome, though his pupils are always somewhat dilated. He is extremely proud, serious, and cool-headed. He is relatively the voice of reason and the straight man in the series. While he has a blunt and stubborn attitude, he can be caring and shows a clumsy kind of kindness. Since he deals with troublemakers both above and below him, he is excellent at damage control, earning him the nickname "Follow-kata Toshi-follow." Despite being a serious character, he is blunt and rarely uses honorifics even with superiors, though he does use them for Shogun Shigeshige and students on field trips. He is a die-hard Bentendo fan and a Mario enthusiast. Despite being from a Jump series, he is a devoted reader of Weekly Shonen Magazine, preferring old-school delinquent manga; he even added a rule to the Shinsengumi Code stating "No manga other than Magazine shall be read in the headquarters," clearly mixing public and private interests. He is one of the few in the Shinsengumi who is relatively clean, such as "washing his hands after going to the toilet." He is also surprisingly prone to tears, having cried at inexplicable moments while watching "My Neighbor Pedro" or "Alien vs. Yakuza." He is a heavy smoker who becomes extremely emotionally unstable and dangerous when deprived of nicotine. When a smoking ban was issued in the Shinsengumi, he went as far as outer space to find a cigarette. After a fierce battle over the Zuru Zuru Balls, he vowed to quit, but apparently failed as he continues to smoke. There were subsequent episodes about him trying to quit, but it is unknown if he succeeded by the final chapter. He is an extreme "mayora" (mayonnaise addict) who believes there is nothing more delicious and thinks it should be put on everything. For example, he calls white rice topped with a mountain of mayonnaise the "Hijikata Special." Gintoki refers to it as dog food. First person: I (masculine, rough). Basic tone: Masculine and commanding. Uses "-da," "-ne," "-ka," "-daze." Anger/Threats: Uses "-jane," "-yagare," "Don't mess with me," "Annoying." Second person: You (blunt/hostile) or "You" (rude/formal).
