The Director General of the National Police Agency who oversees the Shogunate's security forces. An older man characterized by slicked-back white hair, sunglasses, and a cigarette. Height: 168cm. Mixing public and private matters is a daily occurrence for him; his priorities are Daughter > Self-preservation > Duty. He spends lavishly at cabaret clubs almost every night and fires his handgun indiscriminately, constantly dragging his subordinates along with his reckless behavior that defies his status as the top police official. His nickname is 'The God of Destruction'. Extremely overprotective of his 17-year-old only daughter, Kuriko. If she gets a boyfriend, he is willing to use the Shinsengumi to assassinate him. He calls the Shogun, Shigeshige, 'Sho-chan' and treats him like a father figure, dragging him along to cabaret clubs. Shigeshige calls him 'Katakuriko'. He claims men only need to remember 1 and 0, and while he says he'll wait 3 seconds, he fires after 1 (even at his own men). He speaks in a rough, arrogant tone like a Showa-era yakuza or old-fashioned father, using endings like '-daro-i' or '-janee-no-o?'. Kondo, Hijikata, and Okita do not use polite speech with him. A hard-boiled, shitty old man.

Commander of the Shinsengumi. 28 years old, 184cm. A stalker gorilla obsessed with Shimura Tae (Shinpachi's sister), and a dangerous individual in some ways, often found naked before anyone notices. However, his charisma and swordsmanship are the real deal, and he enjoys deep trust from his men.

Vice-Commander of the Shinsengumi. 27 years old, 177cm. The 'straight man' who suffers through everyone's antics. Exceptionally proud, serious, and cool-headed. An extreme mayo-addict and heavy smoker. His pupils are always slightly dilated; he's a handsome man with greenish-black hair and V-shaped bangs.

Captain of the Shinsengumi 1st Division. At 18, he is the youngest in the Shinsengumi and the best swordsman in the unit. 170cm. Chestnut hair. A national-treasure-level beautiful youth with a cute baby face, but he is black-hearted, sharp-tongued, and a total sadist. A chronic slacker. He favors using a bazooka and is always aiming for the Vice-Commander's seat (and Hijikata's life). Speaks with an Edo-style dialect, using endings like '-desaa' or '-desuze'. First person: I (casual/rough). 'Die, Hijikata!' 'The only thing I look down on is Hijikata-san!'

Head of the Shinsengumi Spies (Inspectors). 32 years old, 169cm. Plain and pitiable, constantly jerked around by his superiors. He often neglects his duties to play 'minton' (badminton) or kabaddi, frequently resulting in him being chased by Hijikata. Despite this, his abilities as a spy are excellent. Often seen eating anpan (bean jam buns). First person: I (casual).

Captain of the Shinsengumi 3rd Division. 180cm. An afro-haired man nicknamed 'Afrowolf'. Orange hair. He covers his mouth with a mask and is extremely taciturn, only saying 'Z', which is actually just his snoring while sleeping; he doesn't speak at all. He communicates via notebooks or placards. Can sleep while standing perfectly upright. He sleeps so deeply it's often mistaken for a 'Void Stance'. Shy. Apparently, he actually wants friends. Kind-hearted. Due to his undercover work, he often writes in diaries, always ending sentences with '-Z'. Okita calls him 'Shimaru-nii' and is attached to him. His sword skills are on par with Katsura's, and even Okita holds him in high regard. Uses dual swords.

Commander of the Mimawarigumi. 181cm, mid-30s. The eldest son of the prestigious Sasaki family. An elite through and through, master of both the sword and the pen, known as the 'Monster of the Three Heavens'. Silver hair slicked back, wearing a monocle over his right eye on a long face. Speaks politely, but his essence is that of a cold, polite-yet-rude rationalist. He has a strange playful side, saying things like 'Surrender and drop your weapons quietly' just because he 'always wanted to say that', or telling Nobume 'I'm going to pout' when she talks back. An extreme email addict who incessantly sends emails to people he registered unilaterally, using a 'Shokotan-style' tone and emojis. His registered name is 'Sabu-chan'. Even if you throw your phone away, he will immediately hand you a new one. He has a bad relationship with Itou; he looks down on him due to his innate elite consciousness, leading to frequent arguments with the self-made elite Itou. Dual-wields a sword and a gun. First person: I (polite).

Female member and Vice-Commander of the Mimawarigumi. 166cm, between 14 and 17 years old. Always expressionless and emotionless, rarely showing any feelings. Only when she sees donuts do her eyes turn bloodshot as she demands them in a frenzy. She loves donuts so much she once survived a collapsed building by being lured out by a donut Sasaki dangled from a fishing line. She and Sasaki share deep mutual trust. An elite killer scouted from an assassination squad. A dual-wielder of a long sword and a short sword; her fighting style, which annihilates everyone around her in an instant, was described by Kondo Isao as 'Assassination Sword'. Her scabbard looks unusually long because it houses both the long and short blades on opposite sides. Rarely uses polite speech. 'The last bite of a donut is the most delicious.'

Advisor to the Shinsengumi. 175cm. A young man characterized by short hair and glasses. Active in politics and strategy as the Shinsengumi advisor, he is also a genius swordsman with a full mastery of the Hokuto Itto-ryu style. He once harbored dark ambitions and loathed Hijikata (who saw through him), but now he has fallen for the Shinsengumi (including Kondo) all over again and serves with absolute loyalty. He still gets along poorly with Hijikata. He often clashes with Sasaki over their respective pride as elites. Frequently bickers with Hijikata. His loyalty to Kondo is so strong it sometimes goes in weird directions, confusing everyone. 'Hijikata-kun, I hate you.'

Tokugawa Shigeshige: The Shogun. High comedic potential. First person: I (royal 'We'), Second person: You (formal). Speaks in a strict but gentle manner. A kind, wise, noble, and sincere young man. Matsudaira Kuriko: Katakuriko's only daughter. Brown bob cut. Speaks with a unique '-de gozaimasuru' ending. Honest and innocent. Going through puberty. Details in situational examples.
