A former comrade of Gintoki during the Joi War. Even after the Amanto take-over of Japan, Katsura continues to resist the Amanto, and has amassed a band of followers known as the Anti-Foreigner Faction, which is in continuous, direct conflict with the Shinsengumi.
Although his initial methods were more violent in nature, Katsura has since come to believe that there are people important to him in Edo, and decides that he no longer wants to destroy the country. He and his faction now seek a way to bring about change without causing needless bloodshed.
Since he is a wanted man, Katsura is often seen wearing disguises (which are always completely ineffectual). Katsura sometimes works odd jobs to raise money for his terrorist activities and is often seen trying to coerce Gintoki into assisting him with his eccentric endeavors. He is always accompanied by his pet, Elizabeth, whom he cares deeply for. Gintoki often calls him "Zura," to which he will typically respond with "Not Zura, it's Katsura."
- Accidental Misnaming: People often call him "Zura", but he always corrects them that it's "Katsura". It's later revealed in chapter 564 that "Zura", for him, is personal (as it can be read as "friend"), because he can rely on Gintoki and Takasugi as both a friend and a general, so when he declares "Katsura ja nai. Zura da!" while fighting Shoukaku, he finally embraces it.
- Accidental Pervert: How he meets Ikumatsu. He has to climb at the rooftops to escape from the Shinsengumi. As he is trying to walk with an injured leg, he accidentally grabs a bra Ikumatsu hung up to dry and gets beaten by her.
- Alliterative Name: Kotaro Katsura.
- Asskicking Equals Authority: After the cataclysmic events of the "Silver Soul" arc, the new Japanese government sees Katsura ascending as Prime Minister—which is remarkable considering the highest his historical counterpart ever reached was primarily Imperial Advisor. Not that he gains any dignity for it—especially when he's publicly known as "Donald Zurump".
- Attractive Bent-Gender:
- Invoked as Zurako when he is forced into drag with Gintoki by Saigo.
- If Katsura had been involved in Gender Bender Arc, he might become an actual Zurako. He was in the genderbent anime ending, but looked exactly the same save a bow in his hair.
- Badass Long Robe: Clad most of the time in a blue kimono, and fights quite effectively while wearing it.
- Bishōnen: Comes with his voice actor.
- Bomb-Throwing Anarchists: At least initially. His Cartoon Bombs are still indicative of his scatterbrained nature.
- Brick Joke: Katsura finally embraces being called "Zura" in the tail end of chapter 563. Well, maybe not, given his first act as Prime Minister is to tell everyone that he's Katsura. Old habits die hard it seems.
- Bunny-Ears Lawyer: His actions and reasoning are often incredibly eccentric and strange but he's displayed a shocking amount of competence in managing to evade the Shinsengumi day-after-day. Need it be pointed out again that he fought side-by-side with Gintoki during the Joi War?
- Captured on Purpose: At the start of the Farewell Shinsengumi arc, Katsura lets himself get arrested and sentenced to death as part of a plan to have his Joi faction and the Shinsengumi work together to save him and Kondo.
- "Zura ja nai, Katsura da!". Along with myriad variations such as: "I'm not Zura, I'm Captain Katsura.", "I'm not Zura, I'm Zurako", "I'm not Fruit Punch Samurai, I'm Katsura.", "I'm not Zura, I'm a pine tree.", and "It's not rap, it's Katsu-rap, yo!". Episode 176 has an incomplete list of this, at the time of its airing.
- When he believed his role was taken over by Kyuubei, his new catch phrase was "I am/was on standby the entire time."
- Character Development: Started out willing to go to any extreme to destroy everyone and everything related to the new Edo. Thanks to Gintoki and the Yorozuya, he's softened his stance and only goes against the government and Amanto and is now seen by the Shinsengumi as a moderate rebel. Doesn't mean he's not any less dangerous though. Shown really well in the final arc where he finds out that not only is Elizabeth an alien but also the rightful king of an amanto kingdom, and he still accepts him as family.
- Cloud Cuckoo Lander: He thought that Gintoki could hide from some ronin in an empty tin can, keeps Elizabeth as a partner without so much as a single question (completely ignoring the fact that it's just a guy in a costumenote ), and fends off attackers using poisoned fried rice and curry as a weapon. Heck, when he has a Newtype reaction, he can only say completely nonsensical things!
- Here's a really extreme example: he once went out for a pleasant bicycle ride... through a safari park during the Popularity Poll arc, just because he wanted to see the animals' paws up close—while everyone that has a lower ranking than him wants to kill him.
- Cosplay Otaku Girl: A Rare Male Example. He's so single-mindedly incompetent at disguising himself that it might just be something he does for fun."He likes his pet alright, but he loves his costume" as Kagura put it once when he showed up in Captain Harlock cosplay for the second time. Live on television, no less. Using Captain Katsuura as his alias.
- Combat Pragmatist: While Katsura does value personal honor, he doesn't care about fighting fairly and will freely use bombs to win a fight.
- The Comically Serious: Subverted because we see him doing something utterly stupid or weird more times than we see him be serious, but he remains perfectly serious during all of his appearances.
- Crouching Moron, Hidden Badass: A highly capable and lethal warrior, on par with Gintoki, completely obscured by the fact that he is always seen with a giant duck by his side.
- Cuteness Proximity: Has a weakness for cute animals and will often be overcome with a desire to pet them.
- Dark and Troubled Past: He was an orphan (he lost his parents to an illness and his grandmother followed suit not long after them) and had to learn to survive on his own with the ideal of becoming a strong "coward" samurai to be able to protect his comrades. Eventually, together with Gintoki and Takasugi, he lost a war, and, more importantly, he also lost his teacher, Shoyo. He parted ways from them shortly after Shoyo's decapitation. While he didn't end up obsessed with his death as Takasugi or with apparent apathy as Gintoki, he seemed to be on peace with that, although he became a terrorist against the Bakufu.
- Everyone Has Standards: He may wanted to kill the Shogun, but he wouldn't do it when the Shogun was naked and had his dick out aiming at him. In fact, he insisted Kondo to protect him!
- Eyepatch of Power: Always wears an eyepatch as part of his Captain Katsura disguise. His future self in the second movie also sports bandages over his eye in the same manner as Takasugi.
- Fantastic Racism: Hates the Amantos, and claims they are "soiling" the country simply by living there.
- Flanderization: In his first appearance, he's at least reasonably competent, dangerous, and aware of the world around him, if a bit prone to idealistic ranting. After the debut of Elizabeth, he's a silly Cloud Cuckoo Lander with the naive idealist traits turned Up to Eleven. He's considerably funnier this way.
- Has a Type: Katsura has a thing for young widows, something that goes way back to his childhood according to Gintoki. Katsura proclaims that's not the case; he just likes Netorare.
- Heterosexual Life-Partners: With Gintoki. Gintoki normally thinks of him as a bother, but they've been around each other since childhood. The flip side of that is that Katsura is extremely serious about keeping Kagura and Shinpachi safe, claiming that Gintoki wouldn't forgive him otherwise.
- His Quirk Lives On: His hair and dressing styles as an adult heavily mirror his dead teacher Shoyo's.
- Historical Domain Character: His historical counterpart is Katsura Kogoro, later known as Kido Takayoshi.
- Historical In-Joke: A lot of his characterisation is based on his historical counterpart's nickname "Running Kogoro", as he lived a lot longer than most rebels by virtue of clever disguises and running away when he needed to. In one chapter he hides from the Shinsengumi with a ramen shopkeeper named Ikumatsu. The real-life Katsura met his wife, a geisha named Ikumatsu, while in hiding from his enemies.
- Insane Troll Logic: Just look at the exam he wrote for new anti-Bakufu terrorist's recruits...
- Insistent Terminology: A Running Gag of sorts for him. He always corrects others' Accidental Misnaming as a way of insisting that the things around him should be referred to as their proper terms, especially his own name. The latter move in particular often gets himself into trouble in situations where there is a need for obscurity or for him to hide his identity.
- He tries to get around this occasionally by giving himself aliases that don't stray too far from his actual name(Captain Katsuura, Katsuo, Zurako, etc) , but nonetheless still corrects them to his actual name out of habit.
- And then there are other times where he does correctly use his aliases to refer to himself, but still ends up being corrected to his actual name by others.
- Let's Get Dangerous!: He takes after Gintoki in chapter 562.Katsura: Forgive me, Elizabeth. Everyone. As I am now, I have no chance of winning this fight. As a general of an organization, I cannot beat that thing. So I must go back. Not for the organization, nor my comrades. I will swing this sword for myself. As a lone samurai.
- Likes Older Women: Has a thing for married women and widows, according to Gintoki. While playing a Dating Sim in the Owee arc, he even chooses to romance the heroine's mother instead of the heroine herself. There was also the incident with Ikumatsu, which Gintoki teases him for much later on in the manga.Gintoki: "Zura, might you have ****** with Ikumatsu?"
- Long-Haired Pretty Boy: Long hair? Check. Bishōnen? Check.
- Lovable Coward: He can fight and as long as he is able to protect his comrades, he will run away from losing battles, as indicated by an early flashback in which he tries to persuade Gin to do the same. (See Historical In-Joke above.)
- Master of Disguise: Or so he thinks. He's managed to fool the Shinsengumi at least.
- Meaningful Name: His "Zura" nickname can be read as "Friend" in Japanese. This is important during his childhood, because that way he became acknowledged by both Gintoki and Takasugi as both their general and a friend they both could truly rely on.
- Nice Hat: Often disguises himself as a monk, complete with a monk's straw hat.
- Paper-Thin Disguise:
After accidentally stepping on a kid's toy, disguised as a priest.Kid: "Hey, smelly priest!"
- Whether he dresses up as a priest, as Captain Katsura (Dattebayo/Believe it!), or as Katsuo, almost nobody (excluding Gintoki & co.) ever seems to recognize him, despite baring his unaltered face in plain sight. A lot of times, he doesn't even bother going for secrecy:
- When he's interviewed by Hanano, he's outraged with the network altering his voice, obscuring his face with a mosaic, and using an alias instead of his real name. Instead, he has them stop, using only a pair of gag glasses as a disguise, and he even takes those off just to eat some ramen.
- Pocket Protector: Carries around an old school book which saves his life against Nizo.
- Put on a Bus: Parodied. He was on standby the entire time.
- Red Baron: It's probably a good idea to not take someone with the nickname "Young Noble of Terror" lightly.
- Reformed Criminal: Subverted in that he is still a criminal, just much less extreme. When we first see him in the show, he is in the process of blowing up Edo's Space Terminal, and had been running a campaign of bombings against Amanto embassies upto then. Gintoki's influence urges him to seek more peaceful methods for reforming Japan. This is seen in the way that many of his later terrorist acts are largely harmless, such as his plan to attack the Shinsengumi headquarters in order to hang their toilet paper the wrong way.
- She Is Not My Girlfriend: Freaks out and denies having done the deed when Gintoki asks him about him and Ikumatsu.
- Shower Scene: While talking about how he sometimes likes to take a whizz in the shower.
- Sleeps with Both Eyes Open: He sleeps with his eyes open.
- Snark Ball: Has his moments.
- Sobriquet Sex Switch: Everyone calls him Zura by mistake; his crossdressing "persona" is named 'Zurako'.
- Suspiciously Specific Denial: When Gintoki tries to tease him about his relationship with Ikumatsu, Katsura gets really detailed with what he denies to be wanting:"Don't be stupid! As if Ikumatsu-dono and I would ever have ***, get *** and ***, or worse, *** like ***!""Screw you! When did I say I wanted to plunge into Ikumatsu-dono's ***, ***, or ***?"
- Traumatic Haircut: In the Benizakura Arc. It's grown back the next time we see him.

Katsura's right hand... duck/penguin-costume-guy-thingy. Originally a present from Sakamoto, Elizabeth hangs around with Katsura, who doesn't even think twice about treating it like a dear friend (and not some person in a costume). It almost never talks, preferring to communicate with signboards (which it uses as weapons, whenever necessary).
- Alternate Company Equivalent: A Japanese counterpart of Will E. Coyote of the Looney Tunes franchise. Considered both are well known for Talking with Signs.
- Amnesiacs are Innocent: Is Prince Hata's older brother with amnesia. He has left quite the trail of blood behind him. Still, Katsura accepts him as family when he finds out and allows him stay with him.
- Author Avatar: It has been revealed that underneath the costume is the director, although this is obviously a non-canon gag exclusive to the anime adaptation.
- BFG: Sometimes uses a bazooka.
- Carry a Big Stick: His Bad Future self in the second movie wields a huge spiky mace.
- Everything's Better with Penguins: Or ducks... or whatever Elizabeth is supposed to be.
- Future Badass: His Bad Future self in the second movie is extremely buff and fights with a huge spiky mace.
- Homage: Elizabeth seems to like dressing up as a reference to Golgo13, while Eren is a complete shout out to Amuro Ray. Heck, they even pilot the same Gundam and are voiced by the same person.
- Irony: He's part of the Anti-Foreigner Faction, despite being an Amanto himself.
- Long-Lost Relative: As mentioned in Put on a Bus below there are many different Elizabeths doing shifts. It seems like the regular one is Prince Hata and Prince Barkas' older brother Dragonia who was known for his long chinko and who seemingly died at the age of 5 after falling off a cliff. But he was actually saved by what appeared to be Renho. After his real identity is revealed however, he refuses to go and rule Oukoku, instead referring to himself as "Elizabeth of Earth".
- Paper-Thin Disguise: Elizabeth's appearance already seems like a costume, but look at Elizabeth when it's running, and you'll see flippers being worn by hairy legs. More obviously, when its mouth is open, you can see either glowing eyes or a man (non-canonically, the director).
- Put on a Bus: Subverted! In probably the greatest moment of trolling in the series, at the end of the Renho Arc Elizabeth/General Eren presumably leaves with the rest of the Renho forever, only for it to be revealed that General Eren was just a temp who fills in on mondays while the regular Elizabeth is away.
- The Quiet One: It talks once in a while (emphasis on while), but usually, it just communicates through instant signboards.
- Rightful King Returns: Is the king Oukoku wants as he's the most fit with the hugest chinko and best leader skills to boot. But gives it to his younger brothers so he can stay with Katsura.
- The Rival: He strikes up a rivalry with the Shinsengumi's Saito Shimaru... because they have the same gimmick of talking with signboards.
- Significant Birth Date: Shares name and birthday with Elizabeth I. Foreshadowing him being the Rightful King of a kingdom.
- Taking the Bullet: When Enshou launches several energy blasts at Katsura, Elizabeth blocks them with his body, before falling over heavily injured.
- Talking with Signs: Always uses signboards to communicate. Well, except for the times he's the director...
- Undying Loyalty: Towards Katsura. Whom he is willing to give up his kingdom for.
- Weapon of Choice: Those signboards. Well, that, or the bazooka.

A former comrade of Gintoki during the Joi War. He is perpetually cheerful and upbeat even in the most dire of situations. Despite his goofy nature, Sakamoto is actually a successful businessman and pilot with a private, well-equipped defensive business fleet: The Kaientai. Sakamoto's goal is to use trade to improve relations and negotiations between Earth and the Amanto in order to bring about freedom in a peaceful manner.
- Advertised Extra: He more than once complains about how he rarely participates in the main story despite frequently showing up in the anime openings, endings and merchandise.
- Badass Longcoat: Wears a long coat in the present. Subverted most of the time, as he rarely ever does anything badass while wearing it, but it makes it all better when he is badass.
- Beware the Silly Ones: He's all laughs and smiles until he's angry. And when he's angry, he's furious, as shown when he demands the Chidori captain to give Mutsu back when he appears to have captured her.
- Blasting It Out of Their Hands: He's a good enough shot to shoot enemy guns out of their hands.
- Bring My Red Jacket: He wears a red longcoat and is prone to being physically abused and bleeding.
- Bunny-Ears Lawyer: He may be goofy, but he's actually a quite competent businessman (when he actually does work that is). During the Renho Arc, he even gets most of the Renho to join their side by working out a business deal.
- Career-Ending Injury: Batou of the Harusame cut up his right hand with a beam saber during the war, leaving him with a nasty scar and a hand that can no longer properly wield a sword.note
- Chekhov's Gunman: A few casual mentions of him are made when Katsura receives Elizabeth as a present from him. When he makes his proper introduction, he's stated to be part of the famous Joui 4 alongside Gintoki and good with ships which comes to be important later in the plot.
- Chivalrous Pervert: A goofy variation of this. He makes it clear he appreciates the ladies and/or their assets, but is as polite to them as he is to other people.
- Cloud Cuckoo Lander: Sakamoto's mind is not of this world. When Nobunobu is stuck with him while he's being held prisoner by his crew and they're fighting against the enemy on Rakuyou, he attempts to analyse Sakamoto's strange decision-making and wonders if he's just really impressive in his own way (before Mutsu beats them both up and clarifies that, no, Sakamoto really is just an idiot).
- Cool Shades: Always wears sunglasses in the present day unless they get knocked off in battle.
- Crouching Moron, Hidden Badass: Though he doesn't get much of a chance to show the 'badass', he did fight alongside Gintoki and Katsura during the Joi War and does have his moments in the present.
- Dark and Troubled Past: Despite his incessant laughter, Sakamoto actually suffered a lot from losing most of his friends during the Joi War. This is what motivated him to leave Earth and start a new life as a businessman.
- The Fool: Manages to make his way in the world with a positive outlook despite his sheer idiocy.
- Genius Ditz: A very competent businessman, but he's too busy acting like an idiot most of the time.
- The Gunslinger: Now prefers a pistol to the sword he used to wield during the Joi War. Later explained by losing proper mobility in his right hand when Batou of the Harusame cut it up.
- Heterosexual Life-Partners: When they were younger, he said that he was only willing to try flying because he knew Gin was waiting for him on the ground. Gin is impatient with him in the present day, but both are willing to risk their lives for the other.
- Historical Domain Character: Based off of Sakamoto Ryouma. Ryoma, in history, was best known for brokering the alliance between the anti-Shogunate domains of Satsuma and Choshu, spearheading momentum for the Meiji Restoration. The latter part of the series finally picks this up when Tatsuma's resources and actions become instrumental for the protagonists' comebacks.
- The Hyena: He is always laughing in the most annoying manner, even while getting bitten or after having his head smashed into the ground.
- Informed Ability: In the anime-only episode about him, Gintoki mentions Sakamoto was a great samurai during the Joui War. While footage of him fighting in the war in the anime and opening/ending sequences (for example Opening 5 and Opening 18/the Gintama. opening) show he indeed fought on par with the other Joui 4, there's no proper fight scenes of him in the flashbacks to confirm how good of a swordsman he was. In the present day readers never get to see him demonstrate these skills either, since he's switched to using guns and is also now unable to wield a sword thanks to the injury on his dominant hand. Takasugi also made an offhand comment of how terrible Sakamoto was as a samurai in a flashback (although since he had just got injured that could had just been Takasugi exchanging banter with him to lighten up the situation), so it's unclear overall where his swordsman skills stood.
- Keet: A rare grown-up example. He's been the most optimistic out of the Joui 4 ever since he joined them, always cheerful and energetic, and prefers to talk things out rather than fight.
- Made a Slave: He was once captured and enslaved by the Chidori Space Pirates, which dealt in human trafficking and which Mutsu was part of due to her father being its leader. Sakamoto ended up stealing the whole fleet with the help of the human slaves and Mutsu. This then turned into the Kaientai merchant fleet.
- One Head Taller: Sakamoto, who's quite tall to begin with (the tallest out of the Joui 4), is a head taller than his co-worker Mutsu, who he greatly appreciates but otherwise doesn't show romantic interest in.
- The Pollyanna: Rare Male Example. He can somehow find an optimistic explanation for waking up to being eaten by a giant dog."(...) Must've sweated while I was asleep too. Eh? Why's everything going red? ...Oh yeah...I was drinking tomato juice.""Look, there's a limit to positive thinking, okay?!"
- Retired Badass: After suffering a Career-Ending Injury during the War, Sakamoto has more or less retired from combat. While he's still a gunslinger and is shown to be pretty good at combat when there's no other choice, he looks for the peaceful solution as much as he can.
- Running Gag: Refers to Gintoki as "Kintoki" for a good chunk of the series, which replaces the "silver" kanji with "gold" kanji. Gintoki's usually pretty annoyed every time he does it.
- Snake Oil Salesman: A Professional trader, but he also has a habit of trading complete crap.
- Strange Minds Think Alike: Seeing as he was the one who gave Elizabeth to Katsura as a gift, it's probably safe to assume that these two are the only ones who operate on the same wavelength.
- Technical Pacifist: He doesn't like pointless battles and will try anything to resolve conflicts without violence. But if you challenge him, all bets are off.
- Uncle Pennybags: According to Gintoki, it was Sakamoto who managed to raise the funds to support their army during the Joui War.
- Urban Legend Love Life: There's a brief mention that he can "only handle Earth women" and Mutsu implies that he may have once or twice caught an STD, but we never actually see any evidence one way or another, as all the women he hits on reject him.
- Verbal Tic: Ends many of his sentences with the suffix "-o" which is an informal way of emphasizing the whole sentence.
- Wide-Eyed Idealist: Believes there is a way to bring about peace in a non-violent manner whereas Gintoki has succumbed to indifference and both Katsura (initially) and Takasugi have resorted to terrorism to bring about change.
- You Wouldn't Like Me When I'm Angry: It takes a lot to get him angry for real. But when he's pushed to that point, things get ugly quite fast.

Sakamoto's serious, down-to-earth second-in-command, and the real leader behind the Kaientai.
Competent and reliable, Tatsuma usually leaves her in charge of everything while he's away... which is 90% of the time. A Running Gag in the series is her trying to find him. As we later learn, she's actually a Yato and former member of the Chidori Space Pirates.
- Action Girl: It takes a long time, but the arc detailing her backstory finally shows off her fighting skills, revealing her to be one of the strongest female characters in the series.
- A Day in the Limelight: After more than 400 chapters since her introduction and never having been in the spotlight for long, we finally get an arc detailing who she is and where she comes from, starting with chapter 477.
- Balloon Belly: In chapter 599, she is shown to be as much of a Big Eater as fellow Yato Kagura and Kamui, complete with a full belly that disappears shortly after.
- Beleaguered Assistant: Played straight and subverted. While she is Sakamoto's assistant, she's only truly suffering as one when he's aboard his ship. When he isn't, she's the one in charge.
- Bifauxnen: Downplayed. She dresses and speaks like a man in the present day, but her femininity is still obvious and she doesn't go out of her way to pretend to be a man.
- Blasting It Out of Their Hands: Like her boss, she's a good enough shot to blast enemy guns out of their hands.
- Combat Stilettos: Wore high-heeled boots into combat when she was younger.
- The Comically Serious: She's constantly serious and composed, so any time a comedic situation involves her, she doesn't need to emote much to be funny.
- Crazy-Prepared: She had the Kaientai fleet modified into a Combining Mecha behind Sakamoto's back just in case they had to work out business deals with giant aliens, which proves useful in defeating the Renho's artificial planet.
- Curtains Match the Window: In the anime at least, her eye color is a light brown and the same as her hair.
- Deadpan Snarker: Prone to deadpan comments over somebody's antics, usually her boss.
- The Gunslinger: Carries around a pistol as her weapon and is a good enough to blast guns out of the enemy's hands though.
- Historical Gender Flip: She is based on the historical Kaientai member Mutsu Munemitsu, who was a man. The historical Mutsu would also spend the rest of the Meiji Restoration as a high-level government official and diplomat—so there's actual basis for this Mutsu to be as high-functioning as she is.
- Hypercompetent Sidekick: Mutsu is so much more competent than her boss that she's effectively the one in charge, even when Sakamoto is on board.
- Intergenerational Friendship: She has a close friendship with Umibouzu, since he and her dad were old acquaintances, and he often worked as her bodyguard.
- Miser Advisor: In the anime she tricks Gintoki into getting less pay for a job—that is, finding her boss.
- Nice Hat: Wears a large straw hat all the time, only taking it off when invited at somebody's home. Its large size also serves to shield her from the sun, being a Yato and all.
- Not So Stoic: Tries to maintain a calm and serious appearance, but she occasionally flips on her boss in anger over his sheer stupidity.
- Number Two: Serves as Sakamoto's second-in-command, which means she practically runs the entire Kaientai most of the time.
- Pirate Girl: Used to be a high-ranking member of the Chidori Space Pirates as a teen, before she joined up with Sakamoto.
- The Reliable One: To Sakamoto. She always backs him up during his dealings and transactions or when they're fighting.
- The Stoic: Controls her emotions well and so doesn't show much expression. She's no Ice Queen, though, and is generally just serious.
- Super Strength: She is later revealed to be a Yato with strength capable of stopping an escape vehicle dead in its tracks and is just as capable of punching a huge hole in it.
- Taking the Bullet: When Hankai launches a surprise attack on Sakamoto, Mutsu pushes him out of the way, getting stabbed and infected by his nanomachines, but manages to survive. Later happens again when Enshou tries to stab Sakamoto with his expanding beam saber, pushing him out of the way and getting impaled in his place.
- The Woman Behind the Man: She pretty much runs everything concerning Sakamoto's business.
- Women Are Wiser: A variation. She isn't more moral than Sakamoto. Just more realistic and practical.
People from Gintoki's past
Voiced by: Kōichi Yamadera (JP), Simon Hayama (EN, series), David Wald (EN, movie)
The swordmaster who taught Gintoki, Katsura and Takasugi everything they know. He was unjustly accused of trying to raise an army and executed by the government, in return for saving his students' lives.
- The Atoner: It is implied that he had a bloody past, which he tries to atone for by teaching children in the countryside. Later confirmed when it's revealed he was one of many Utsuro's selves, the leader of Naraku.
- Back from the Dead: Utsuro who was defeated and thought to be dead... was reborn as Shoyo from another Altana gate hence greeting Gintoki with a genuine smile when he grows fast into a boy. Even after taking his heart out for Gintoki to keep from the Naraku remnants, his body is still on life support as they plan to have him come back as Utsuro.
- Charles Atlas Superpower: He's strong enough to knock people straight down into the ground with a simple tap to the head—normally Played for Laughs against his unruly students. This of course gets a darker nuance when it is revealed it's because he was the superhuman villain Utsuro.
- Decapitation Presentation: Gintoki, Katsura and Takasugi learned of his execution when they received his head. Except not, Gintoki was the one forced to kill him. They just left the head behind for the three of them to look at afterwards.
- Disappeared Dad: He was effectively Gintoki's father figure. He's long dead by the time the series takes place because Gintoki had to kill him.
- Face Death with Dignity: While his death isn't immediately afterwards, last he's seen alive he allows himself to be taken by the Naraku while making his promise to Gintoki. When his time of death actually comes, he accepts it willingly to ensure his three students survive.
- The Faceless: His eyes aren't shown until a flashback in the Courtesan of a Nation Arc, which showed him to look either like a long haired and gentle version of Sougo, or a white haired version of Katsura.
- HeelFace Turn: Had his moment in abandoning his past as one of many Utsuro's selves and changed to become a better person as a way to supress and resist his immortal identity in all possible means. This lasted until a grown up Gintoki was forced to execute him, which led him to come back to life as Utsuro again when the Naraku tried to burn his corpse.
- Historical Domain Character: Loosely based on the historical Yoshida Shoin.
- Keigo: He spoke very politely at all times, even when he was being scary.
- Long-Haired Pretty Boy: Long-haired? Check. Boyish good looks? Check.
- Mentor Archetype: Considering how he taught Gintoki, Katsura, and Takasugi everything they know about the path of bushido and the amount of respect those three still have for him in return, Shoyo-sensei definitely qualifies despite appearing only in brief flashbacks.
- Off with His Head!: The Bakufu ordered him executed and had his head cut off. The person who did said deed? Gintoki, by way of a Sadistic Choice to kill either his own teacher or his friends. This later led to Shoyo coming back to life as Utsuro again after being burned on a pyre.
- Parental Substitute: He's effectively the closest thing to a father Gintoki's ever had.
- Perpetual Smiler: Has a cheerful smile constantly plastered on his face.
- Posthumous Character: He's dead in the present time of the series, but we learn of him through flashbacks and accounts from other characters.

The phantom fifth man of Gintoki's comrades during the Joi War. A team player and supporter, he was so forgettable that even his friends forgot about him during the war. In fact, they even forgot he was left in the temple they lured the Bakufu forces into and blew up, since they were playing kick the can and he was counting. Remembering this event, they begin fearing Kurokono has returned to take his revenge on them at a reunion party he supposedly invited them to. When it proves to be a plot from the Kiheitai to take out Takasugi's former comrades, Kurokono himself shows up to stop them, proving the phantom fifth man is real and alive.
- Big Damn Heroes: Shows up to save Katsura and Sakamoto from the Kiheitai.
- The Faceless: To enforce how people forget about him and cant remember his face, his eyes are always obscured when his face is shown.
- Forgettable Character: Gintoki, Katsura and Sakamoto all completely forgot about him until the fake reunion planned by Henpeita. They had to go through a flashback to discover that he might actually have died. Not that he did anyway.
- The Generic Guy: Apparently seen as so generic and helpful that people forget about him completely.
- Homage: He is a complete Shout-Out to Kuroko's Basketball. Not only is his name in Japanese order Kurokono Tasuke, he has Kuroko's voice actor, is referred to as the phantom fifth man, and has a special talent for avoiding attention.
- Overshadowed by Awesome: Despite being pretty good in his own right, he is completely overshadowed by the feats of his friends. He is pretty content with helping them out from the shadows though.
- Remember the New Guy?: Invoked and parodied; he suddenly gets introduced into the story as the fifth phantom member of Gintoki's war comrade, but Gintoki, Katsura, and Sakamoto all have a hard time remembering who exactly he is.

This legendary warrior once fought in the war against Amanto. Known as Pakuyasa, he cut his way across the battlefield, his white hair and clothes colored red with blood. During the war, he fought against the great swordsman Batou of the Harusame to avenge his wounded comrade. Unable to kill him, Batou has been looking for him for ten years in order to fight him again, seemingly finding him during the battle on the planet Rakuyo.
In reality, Pakuyasa was just a self-proclaimed disciple of the great Shiroyasha, Gintoki. He lacked any real skill with a sword, but had a lot of passion, so he was put in charge of food supplies. When Batou fought him, his mind-reading third eye picked up on Gintoki's powerful killing intent, putting him in a fight against an illusion and making him confuse the two.
He left the war after a short while because he was not cut out for it, opening up a candy shop. After he got sued, he opened a lingerie shop and got arrested for public obscenity. Now he does sketchy odd jobs, just like Gintoki.
- Fan Disservice: When Gintoki talks about him opening a lingerie shop, we get a shot of him wearing said lingerie. Appropriately he was arrested for public obscenity.
- Identical Stranger: Parodied. He almost resembles Gintoki during the war, having white hair and wearing the same outfit, except he's fat. Batou somehow still confuses him with Gintoki.
- Mistaken for Badass: Batou thought he was the most amazing warrior he has ever fought and confuses him with Gintoki, but he is actually a novice with the sword who left the war shortly after. The reason Batou is mistaken is because his mind-reading third eye picked up the nearby Gintoki's powerful killing intent, putting him in an illusionary battle against him.
- Non-Action Guy: Batou thought he was a great warrior, but he actually has little skill with the sword, which is why he left the war shortly after.
- Only Known by Their Nickname: Pakuyasa is just a nickname he was given during the war, while his real name is never mentioned.
- Worthy Opponent: Batou thought he was the most amazing warrior he ever fought against and is excited when he encounters Gintoki on Rakuyo, having confused not only the two's appearances, but also their fighting skills.

- Summon Magic: He's able to call upon a lot of shikigami, though he generally only uses them to non-violent ends.

Although the two started out as friends despite the struggle between their clans, Doman was pressured by his father into trying to defeat Seimei and surpass his clan. He eventually became bitter after the years of humiliation he suffered in trying to defeat Seimei and his hatred of his former friend has since then grown.

A popular Idol Singer popularly called Otsu, who's sung multiple hit singles with surprisingly foul lyrics ("Where the hell is your mother from?").

The shrine was burned down in an incident with loan sharks and since then, Kondo never returned and the chief priest turned into the thief Kozo Etekichi.
- Animal Motifs: Definitely monkeys. His given name as a thief (Etekichi Kozou) can be translated as "Lucky Monkey Boy", hes the chief priest of a shrine dedicated to a monkey god, and he hands out bananas to the poor.
- Cool Old Guy: He might be too old for it, but he still goes out of his way to expose the real criminals and gives out food to the poor.
- Go Out with a Smile: Dies with a proud smile, while holding hands with his student Kondo.
- Just Like Robin Hood: Takes the money he steals from criminals and buys bananas, which he then distributes to the poor.
- Mentor Occupational Hazard: Kondo's old teacher who appropriately ends up dying while sharing a heartfelt moment with his student.
- Only Known by Their Nickname: His real name is unknown as he is only referred to as "Etekichi Kozou", which is a nickname meaning "Lucky Monkey Boy".
- Stealth Clothes: Appropriately for a thief in the setting, he wears a handkerchief over his head which is tied under his nose. Surprisingly for the trope, hes actually competent.
