- Badass and Child Duo: Sugimoto Saichi is a Shell-Shocked Veteran of the Russo-Japanese War known for his uncanny survivability, earning him the nickname "The Immortal". Asirpa is a young Ainu huntress and survivalist who helps him look for the legendary gold in Hokkaido to avenge her father. Even though she is capable in her own right, he is very protective of her. Meanwhile, she trusts him completely so much that when told that he dies from a shot in the head, she manages to believe that he's still alive.

Sugimoto Saichi: "The Immortal"
Voiced by: Chikahiro Kobayashi (Japanese), Ian Sinclair (English)
- Adorkable: with the Ainu children, Sugimoto loses all seriousness and readily plays with them.

- Bayonet Ya: Sugimoto is handy with his type 30 bayonet.
- Berserk Button: Hurting Asirpa in any way, even vocally. Sugimoto was also ostracized because of tuberculosis, so he sympathizes with the Ainus' predicament as sub-citizens of Japan.
- The Berserker: Sugimoto would make Vikings proud by how ferocious he was during the battle of Hill 203. Whenever he battles multiple foes, Sugimoto goes for the most violent way to finish off his opponent, disregarding the wounds he suffers at the same time.

- Did Not Get the Girl: Umeko, the love of his life, married Toraji his childhood friend when he was away from the village.
- Eyes Are Unbreakable: A bear digs its claws into Sugimoto's face, and miraculously avoids his eyes.
- Feed by Example: In a Running Gag, Sugimoto repeatedly tries to demonstrate to his companion Asirpa that the miso he carries is not, in fact, osoma (poop) by eating it. Asirpa responds with either disgust or simply mocking him for eating poop.
- Feel No Pain: Being stabbed through the cheeks with a skewer doesn't faze him.

- Friend to All Children: Sugimoto goes well with children.

- Going Native: Downplayed. He adopts several Ainu habits such as saying "Hinna hinna" when something is delicious.
- Good Scars, Evil Scars: has three scars on the face. Two of them are perpendicular and across his whole visage, while the third deviates from the horizontal one like a tree branch.
- Healing Factor: Has an superhuman ability to heal very quickly from serious injury, even a headshot didn't put him down for long.
- Healthcare Motivation: He needs money quick because he wants Umeko to have her eyes treated in America before diplomatic relationships between Japan and America go too sour.
- Heartbroken Badass: Sugimoto Did Not Get the Girl and when he had the occasion of making up for that, Umeko couldn't recognize him with all the Killing Intent he was releasing as a Shell-Shocked Veteran. Especially tragic since Umeko did love Sugimoto.
- It's Not You, It's Me: After Sugimoto burned his house and revealed his intention of fleeing the village to Umeko, she begged him to take her along, but he refused, suspecting that he too contracted tuberculosis and didn't want her to die.

- I Want My Beloved to Be Happy: He goes through a lot for Umeko's sake.
- Killing Intent: Seems to exude a large one constantly.
- Last-Name Basis: Everyone but Umeko calls him by his surname.
- Loss of Identity: When he came back from the war, the blind Umeko recognized a different man from the one who left the village.
- Love Triangle: He and his friend Toraji loved a woman named Umeko deeply. Toraji married her and when he died in the war, made Sugimoto promise to take care of her.
- Made of Iron: He has survived, among other things, tuberculosis, the worst battles of the Russo-Japanese War, multiple bear attacks, falling into a river during a blizzard, numerous injuries from his skirmishes with the elite 7th Division, and even losing part of his brain after getting shot in the head. He is also known as "the Immortal," both for surviving mortal injuries and for recovering from them almost immediately.
- Mr. Fanservice: Sugimoto has been naked and has exposed his gorgeously sculpted (albeit heavily scarred) body more times than women have been even implied to.
- Nice Hat: Sugimoto sports a military cap.
- Not Hyperbole: A man tricked his group into entering a stenka to get a stolen dog back. Sugimoto warns him that, should they win, if he doesn't give them back the dog immediately, he would rip every hair out of his head. They win. The man tries to weasel them into another fight to get the dog back. Sugimoto rips every hair out of his head right there and then, with his bare hands.
- Pragmatic Hero: He needs the treasure and doesn't hesitate to kill his enemies and skin them for the map.
- Prospector: Briefly becomes one in Hokkaido after the war and before looking for the treasure.
- Reality Ensues: Getting punched hard in the head just a few days after miraculously healing from bullet-caused brain damage is NOT a good idea, even for Sugimoto the Inmortal.
- Reality Is Unrealistic: His aftermath for brain damage qualifies: instead of commonly depicted highly visible results (like losing mobility or speech), he's shown without any apparent effect. However, one of the many possible results of brain damage in the area he was shot is mild dyslexia, and an exaggerated emotional answer. And next chapter, he's actually shown consistently taking out the wrong photo, being all teary-eyed at having found Asirpa's track, and acting much easier to anger, even for his usual standards.

A subplot develops with Koito refusing to tone down his performance and Sugimoto trying to outdo and eventually ruin Koito's show.
- The Social Darwinist: Only in a fight situation but he makes it clear that in a matter of life and death, the strong survive and the weak perish.
- 'Tis Only a Bullet in the Brain: He gets shot in the head by Ogata, and for all his Healing Factor, does show the realistic effects of brain damage afterward, though they are pretty mild in his case: slight dyslexia and enhanced emotional response he becomes significantly more sentimental and easier to anger afterward.
- Trademark Favorite Food: Miso goes well with anything to him.
- Unfriendly Fire: Sugimoto admits to having almost killed an officer who pissed him off.
- Weapon of Choice: An Arisaka Type 30 rifle plus a bayonet.
- Where I Was Born and Razed: Sugimoto burned down his house to have "a clean slate" and sever his ties to his native village.
- Wounded Gazelle Gambit: Fakes being on the verge of death to convince Tsurumi that he's willing to cooperate as long as they bring him to the hospital, enabling his escape from the 7th Division.
- Worthy Opponent: To both Hijikata and Ushiyama. Both saw Sugimoto kicking ass and praised him directly, looking forward to the moment Sugimoto would clash with them.
Voiced by: Haruka Shiraishi (Japanese), Monica Rial (English)
- Action Girl: Asirpa doesn't kill people, but still participates in the action.
- Ancestral Weapon: Her menomakiri, a dagger made for women, was crafted by her father.
- Archer Archetype: She uses a bow with great accuracy to hunt bears. She's usually calm, but sometimes Not So Above It All.

- Badass Native: She is an Ainu on the island of Hokkaido.
- Badasses Wear Bandanas: Asirpa wears an Ainu bandana.
- Broken Bird: She is noted to have rarely smiled ever since her father died, and only Sugimoto would break that stoicism.
- Can't Hold His Liquor: Justified since she's probably never drunk alcohol.
- Cerebus Retcon: She is surprisingly adept at hunting and survival in the mountains for a little Ainu girl, especially in a culture where women are expected to Stay in the Kitchen. It is mostly presented in a lighthearted way to expose the most interesting parts of Ainu culture, and seemingly give Sugimoto a competent Kid Sidekick. When Sugimoto meets the real Noppera-Bou/Wilk in Abashiri Prison, the disfigured prisoner confesses that he had been secretly grooming her into becoming a freedom fighter waging war against the Japanese government for the Ainu, using hunting and survival training as a pretext. The Reveal is all the more shocking since Asirpa is a Badass Pacifist and a follower of Thou Shalt Not Kill, yet Wilk planned for her to eventually become a martyr through violence.
- The Chief's Daughter: Her grandfather was the most important man in her village.
- Clingy Jealous Girl: Implied. When Sugimoto tells the group that he wants the gold for the widow of his friend, Ogata asks Sugimoto if she and the woman Sugimoto loved is one and the same. Asirpa suddenly dances with a darkened face and later gets a Luminescent Blush as she answers Sugimoto that she did the Crane Dance because the group ate a crane.
- Conveniently an Orphan: Both her parents died when Asirpa was young. Thus she spent time in the mountains acquiring her hunting skills.
- Cradle of Loneliness: Asirpa is cradling to Retar, whom she and her dead father raised together.
- Curtains Match the Window: Has dark blue hair and eyes.
- Daddy's Girl: Asirpa has nothing but fond memories of her late father and praises his ability as a hunter. He's also the one who taught her how to hunt, although Ainu women typically stay at their village. Justified in that her mother died of illness right after giving birth to her.
- Exact Words: "I won't kill you" (emphasis added). Said during a Mexican Standoff with Ogata, who calls her bluff for her Thou Shalt Not Kill creed. Cue a very angry Sugimoto right behind him.
- Fire-Forged Friends: With Sugimoto after they work together to kill a man-eating brown bear.
- Gender Is No Object: Surprisingly, nobody ever cares about her gender, even though the series takes place in the 1900s and Ainu culture expects women to Stay in the Kitchen.
- Good Cannot Comprehend Evil: She asks why Anehata would kill the animals with whom he's made love if he knew how wrong his actions were.
- Good Is Old-Fashioned: Downplayed, Asirpa follows her culture but ignores some customs such as being tattooed around the mouth when she is near to age.
- Gratuitous Foreign Language: She speaks Japanese fluently but mixes her speech with Ainu words.
- Hair Color Dissonance: She's portrayed in the manga artwork and the anime as having dark blue highlights in her black hair. Her hair is outright dark blue on the covers for Volumes 2 and 11 of the manga.

- Hypocrite: Asirpa has a rule against eating man-killing animals but finds excuses to eat them anyway because she's hungry.
- I Do Not Like Green Eggs and Ham: At one point, Asirpa becomes convinced that miso is poop and refuses to eat it. When she forces herself to try a Japanese dish with miso, she finds it delicious.
- I Know Your True Name: Hijikata knows the Japanese name she has in the family registry. It's "Asuko Kochoube", the one clue Noppera-Bou gave Hijikata about Asirpa's identity.
- Innocent Blue Eyes: Asirpa has blue eyes. It becomes plot-relevant when it's revealed her father came from Russia and the eyes confirm her link to Noppera-Bou.
- Jabba Table Manners: One omake has Asirpa managing to get a whole boiled otter's head on her cheek while eating.
- Jeanne d'Archétype: Invoked. Wilk had been secretly grooming her into becoming a freedom fighter waging war against the Japanese government for the Ainu, using hunting and survival training as a pretext. Once Sugimoto finds about the truth, the Japanese ex-soldier calls him out for trying to make her some Ainu Joan of Arc because it would mean she has to be a murderer.
- Little Miss Badass: Asirpa is only 11 or 12 years old, and though she doesn't fight people, she's the most adept survivalist and hunter of her group. In fact, she was hunting bears with her father before that. It turns out Wilk had been secretly grooming her into becoming a freedom fighter waging war against the Japanese government for the Ainu, using hunting and survival training as a pretext.
- Long Hair Is Feminine: Played with. She is the only girl of Sugimoto's group and has the longest hair down to her mid-back. However, she has no skill in typically female occupations, much to her grandmother's worry.
- Master Poisoner: Asirpa can cook deadly poison able to take down bears.
- Meaningful Name: Asirpa means "new year" but can also mean "future" in Ainu, reflecting that she calls herself an Ainu woman for a new era because while she respects the Ainu traditions, she doesn't follow all of them blindly. Meanwhile, her Japanese name, Asuko Kochoube, comes from the Japanese word for tomorrow (asu) and a locational surname derived from Kochōbetsu in Tōbuchi, Sakhalin. The first name roughly corresponds to her Ainu name, while the surname foreshadows that her father is a half-Polish half-Sakhalin Ainu settler. As her father wanted her to become a figurehead for an eventual Ainu uprising, her names take on a much darker meaning.
- Mixed Ancestry: She's very much an Ainu girl, but Hijikata speculates early on that she has European ancestry upon seeing hints of green in her blue pupils. Downplayed, as she's the daughter of a half-Polish half-Sakhalin Ainu settler and his Hokkaido Ainu wife.
- Ms. Exposition: About the Ainu culture.
- Obsessed with Food: She is always eager to eat.
- Pelts of the Barbarian: Asirpa wears a fur over her clothes to protect herself from the cold.
- Phenotype Stereotype: Hijikata speculates early on that Asirpa has European ancestry upon seeing hints of green in her blue pupils. Later, it's revealed that her father, Wilk, is half-Polish.
- Please Don't Leave Me: She begged Retar to stay with her when the wolf heard the howl of another wolf. Retar still comes back to her from time to time.
- Reality Ensues: As Makanakkuru mentions, for all her maturity, Asirpa is still a tender young girl dealing with the loneliness of being left behind by her late father and Retar.
- Shipper on Deck: She thinks that Tanigaki and Inkarmat should marry.
- Skewed Priorities: Asirpa running out of her favorite seasoning seems more urgent than really making sure if her father is a murderer or not.
- The Smurfette Principle: She is the only female member of Sugimoto's group.
- Spell My Name with an "S": Asirpa could be alternatively spelled as "Ashirpa", which is used in the official French translations.
- Thank Your Prey: Asirpa thanks her prey by making use of anything possible from them.
- Thou Shalt Not Kill: Not kill humans, otherwise hunting animals is fair game. She strictly adheres to this code. When she sees that her own father is a murderer, she weeps out of disappointment. Even when Kiroranke continuously exposes her to the multiple injustices of the Japanese and Russian governments towards the Ainu and their reprehensible exploitation of the natural resources, Asirpa still wonders if the gold is worth finding at all since it will fund a new bloodshed.
- Training from Hell: She went through harsh training since early childhood by her late father, Wilk, with the secret intent of grooming her into becoming a freedom fighter waging war against the Japanese government for the Ainu. Judging from what is shown in the series, it involved telling her to hunt a bear alone when she was seven or younger. As a result, she's the most adept survivalist and hunter of Sugimoto's group.
- Trap Master: As a hunter, Asirpa is, of course, skilled at setting traps, not only for animals but humans as well.
- Tyke-Bomb:Wilk trained her for hunting and survival since her early childhood as a pretext to turn her into a freedom fighter for the Ainu against the Japanese government. Sugimoto, being a Shell-Shocked Veteran, calls him out on going to such extreme lengths for the cause of independence.
- Weapon of Choice: A wooden bow with a string made of whale's dorsal muscle, and Poisoned Arrows.
- You Killed My Father: She wants to take the treasure to get back at her father's murderer.
- Badass Adorable: Has a sweet personality around Asirpa and Asirpa alone, and is still a wolf.
- Big Damn Heroes: Regularly appears to save Asirpa.
- Canis Major: Big enough for Asirpa to ride him.
- Horse of a Different Color: His size enables Asirpa to ride him like a horse.
- Last of His Kind: One of, maybe the last Hokkaido wolf on the island. It turns out Retar has a mate and cubs.
- Meaningful Name: "Retar" means "White".
- Sugar-and-Ice Personality: He acts like a wolf in public, but acts more like a big dog with Asirpa alone.
- Surprise Litter of Puppies: He is friendly towards Asirpa and used to live with her until he left her to live in the wild. He's later revealed to have left because he found a mate and had several cubs with her.
Shiraishi Yoshitake "The Escape King"
Voiced by: Kentaro Ito (Japanese), Ben Phillips (English)
- Accidental Misnaming: Shiraishi is called the "Excrement King" by Asirpa.
- Amusing Injuries: Various animals bite Shiraishi in the head, to his dismay.
- Badass Boast:
- He utters a one-time boast when they ask him if he could break into a certain prison to speak with a convict in there."I've been thrown into every single prison they've got in this country! But there wasn't a single one of them... that I couldn't break out of."
- He boasts about his legendary skill to frighten prison guard.(To an annoying guard, while in prison) "Really, you shouldn't bully me too much... or I'll break out when you're the one on duty."
- He utters a one-time boast when they ask him if he could break into a certain prison to speak with a convict in there.
- Boys Like Creepy Critters: Shiraishi used to have a pet lizard and a pet rhinoceros beetle. It turns out the beetle is an empty shell in which Shiraishi hides small objects such as the copy of his cell's lock's key.
- Butt-Monkey: The one character who draws the short end of all the jokes involving him.
- Crazy-Prepared: He keeps many items in his stomach that do come in handy whenever he's bound, like a cartridge full of gunpowder to break locks.
- Deliberate Injury Gambit: Shiraishi can easily dislocate his joints, enabling him to pass through narrow orifices or escape arm locks.
- Escape Artist: Shiraishi's specialty. He's not only nimble or knows his way around locks, but exploits the organization of the prisons themselves to his advantage.
- The Friend Nobody Likes: Shiraishi is so annoying no one from Sugimoto or Hijikata's groups wish to really take the effort of saving him when he's captured by soldiers from the 7th Division. Only Sugimoto volunteers to save him.
- A Lighter Shade of Black: One of the only sympathetic convict shown so far. It helps that he isn't a murderer.
- Le Parkour: Shiraishi is a practitioner of this.
- Lovable Rogue: He is a convict, but is so far portrayed sympathetically and or comically.
- Master of Disguise: He briefly infiltrated the 7th Division headquarters and slipped away unnoticed, disguised as one of the soldiers.
- The Millstone: Shiraishi screws up a lot. One notable instance is tripping and dropping a bag of bombs into a fire in a building, not only putting the whole group in danger but forcing them to stop their hunt for the gold to replenish their supplies.
- The Mole: Shiraishi secretly works for Hijikata's team after being coerced into occasionally feeding them intel or giving copies of Sugimoto's skins.
- Non-Action Guy: Shiraishi is not a fighter or is he brave, whenever trouble occurs, he flees or hide.
- No Respect Guy: Nobody respects him, nobody.
- Politically Incorrect Hero: Subverted. When he first meets Sugimoto and Asirpa, he asks the veteran if she is his "dog". Sugimoto, outraged, threatens to make him unable to speak before Asirpa says she's used to being called like that because of her Ainu heritage. Sugimoto calls her out because he thinks that no one should be used to such things. Afterward, he stops acting condescending towards Asirpa.
- Red Baron: "The Escape King"
- Screw This, I'm Outta Here!: In Chapter 91, Shiraishi tries to run away from his companions because he knows Sugimoto will learn of his status as The Mole for Hijikata and thus fears his vengeance. However, Sugimoto later puts it behind him, as he checked the skins Shiraishi gave to Hijakata and saw that they were fakes.
- "Shaggy Dog" Story: Shiraishi's flashback involves endlessly chasing after a nun because of a lousy portrait, breaking out of various prisons before inevitably getting captured by the police. In the end, said sister turns out to be as ugly as her picture suggested.
- Stomach of Holding: He keeps some items in his stomach he ties to his teeth for later regurgitation, such as a small razor blade, needle, wires or even cartridges.
- Sweet Tooth: Shiraishi always has some candy on him. In chapter 92, when he's captured by a platoon of soldiers, the only way Hijitaka has found to catch his attention while the soldiers kept on being distracted was to disguise himself as a sweet merchant.
- Tunnel King: Shiraishi can dig through snow very easily.
Voiced by: Masaki Terasoma (Japanese), Ricco Fajardo (English)
- Ambiguously Evil: A definitely shady character, whose true allegiance is not clear yet. It's implied he is part of a conspiration of Russian Ainus who aim to conquer Hokkaido from Japan. He reveals his true colors and stabs Inkarmat in the stomach with his makiri, and it is confirmed after the Abashiri arc that he is one of the Ainu conspirators and revolutionary aiming to take Hokkaido for their people.
- Awesomeness by Analysis: Can predict the outcome of a horserace just by observing the horses, explaining how Inkarmat could predict the results of the race too.
- Bitch in Sheep's Clothing: When Asirpa, Sugimoto, and Shiraishi first meet him, Kiroranke comes across a genuinely kind and friendly man. As Tsurumi finds out, he was once a ruthless member of the "People's Will" movement in Russia. When manipulating Asirpa in Sakhalin, he looks very malicious as he says that he wants her to tell him where the gold is when she grows up.
- Bomb-Throwing Anarchists: Tsurumi discovers that Kiroranke was one during his youth. He was a member of the "People's Will" movement and helped assassinate Tsar Alexander II through a bombing.
- Born in the Saddle: Kiroroanke has been close to horses since youth, which is not so surprisingly considering that the Ainu during the Meiji Era had a reputation for being very good horsemen. Not only he knows how to analyze their behavior, but also he can also outpace experienced jockeys on a heavier than usual horse, with a horrible head start to boot.
- Badass Beard: He shaves it temporarily to disguise himself as a jockey in chapter 61, and it grows back into a stubble not one hour afterward.
- Chubby Chaser: He prefers women fat.
- Demolitions Expert: Part of his former job as a sapper. Kiroranke has a bag of grenades he carries everywhere.
- The Engineer: Kiroranke's job in the Army was that of a combat engineer.
- Instant Soprano: His reaction when Tanigaki grabbed the wrong, uh, extremity when fleeing stark naked in pitch black darkness (they were attacked while at an onsen in the dark of night).
- Manipulative Bastard: Once he manages to separate Asirpa from Sugimoto, Kiroranke wastes no time in grooming her into sympathizing for the indigenous population of Sakhalin against the Japanese and Russian colonization.
- Mixed Ancestry: He reveals that he is part Sakhalin Ainu and part Tatar, also having the name "Yulbars".
Former Private First Class Tanigaki Genjirou
Voiced by: Yoshimasa Hosoya (Japanese), David Matranga (English)
- A Lighter Shade of Black: He is less violent than his comrades in the 7th Division.
- Badasses Wear Bandanas: Tanigaki switches to an Ainu bandana.
- Butt-Monkey: He injures his foot by playing with a pair of sey-pirakka, gets mistaken for Anehata by the local Ainu, and is kicked down from the sled of Enonoka's grandfather for being too heavy.
- Clear My Name: Because Anehata stole his rifle and used it to kill a doe the scholar had raped, local Ainus think Tanigaki's the culprit and want to punish him, forcing the soldier to flee.
- Cold Sniper: He is handy with a rifle, and can out snipe a dedicated sniper team. Moreover, Tanigaki is very analytical whenever he hunts (or is hunted).
- Conflicting Loyalties: Between his unit, his legacy as a Matagi, and basic human decency. Although he stops cooperating with the 7th Division, Tanigaki still doesn't want to fight them and mostly stays neutral because of the loyalties.
- Egomaniac Hunter: Wants to kill Retar for his ego alone.
- Even Evil Has Standards: Tanigaki is an Evil Poacher but involving innocent people in a killing spree is beneath him.
- Evil Poacher: Tanigaki wants to hunt down the last Hokkaido Wolf.
- Foil: To all other soldier or former soldier characters. A major theme in the series is how war changes people and not everyone can change back. By contrast, by spending time in Asirpa's loving village, Tanigaki has managed to put his past as a soldier behind him. This is especially the case with Ogata, who has lived an almost lifeless life. Meanwhile, Tanigaki not only has recovered from war, but also got himself a surrogate family with Cikapasi, Inkarmat, and Asirpa's family.
- Going Native: Downplayed. He starts wearing a customary Hokkaido Ainu clothing after Asirpa's grandmother shelters him.
- Handicapped Badass: Even if he needs crutches to walk, he will kill you.
- HeelFace Turn: He seems to have abandoned his evil ways and cooperates with Sugimoto.

- Manly Men Can Hunt: He is a skilled hunter, on par with Asirpa.
- Manly Tears: In his flashback, Tanigaki shed some of them as he listens to his half-brother, Kenichi's, true story.
- Mr. Fanservice: Tanigaki is practically the manga's idol. His muscled physique is the most regularly exposed out of all the characters (even a formal photo session turns into a gag when the photographer asks Tanigaki to pose in his fundoshi). Moreover, the marketing also puts him at the forefront, with one notable panel during Jump Festa 2018.
- Scarily Competent Tracker: He comes from the Matagi tribe, which lives similarly to the Ainus.
- Signature Item Clue: Tanigaki meets Kenichi in the middle of a battlefield. Kenichi is blind and deaf because of a grenade blast, and Tanigaki eases his pain by offering him some of his kane mochis only the two know the recipe of. The taste of walnut allows Kenichi to recognize Tanigaki despite having no eyes or ears.
- Ship Tease: Has several moments with Inkarmat. The two of them have a Relationship Upgrade when they both have sex.
- Tohoku Regional Accent: Hes from a Matagi village in Akita, and during flashbacks to his time in the village he speaks in a mild Tōhoku dialect. However, in the main events of the story he mostly speaks standard Japanese, with only occasional Tōhoku mannerisms.
- Would Hurt a Child: He doesn't raise his rifle toward Asirpa, but later doesn't hesitate to take her hostage.
- You Killed My Father: Tanigaki became a soldier because he sought revenge on a friend who killed his younger sister, Fumi. It turns out it was a requested Mercy Kill.
- Younger Than They Look: Despite the beard and rugged appearance, he is no older than Sugimoto who is in his early twenties.
- Cold Sniper: Had no problem shooting an old man in the head in an ambush simply for carrying the best rifle. He also shoots a 7th Division soldier in the head after being told by Aspira to shoot them in the foot.
- Facial Horror: Covers up the bottom half of his face after being shot there by Ogata, and is implied to have something genuinely horrifying underneath despite the manga not shying away from horrible facial injuries before.
- Handicapped Badass: Is left unable to speak due to Ogata shooting him in the mouth, but is easily up there with Ogata and Tanigaki as the best marksmen in the series.
- Hidden Depths: Revealed to be a talented artist who when not sniping makes very accurate drawings of people and animals.
- Sixth Ranger: Tried to kill the gold hunters while Aspira was still traveling with Ogata and Kiroroanke, and shoots at them again after being reunited with Sugimoto under the belief Ogata and Kiroroanke were still with them. Ends up becoming a member after following them around for a while and joins them in their escape from Sakhalin.
The Abashiri Convicts
- Affably Evil: Lots of them are polite and friendly, despite their crimes.
- Asshole Victims: They began killing each other when they figured that they needed to be skinned to decipher the map.
- Gold Fever: Zigzagged. While a good chunk of the Abashiri convicts is after the gold, many of the ones featured so far were only interested in escaping prison then resume whatever they were doing before being imprisoned.
- Human Notepad: On the body is tattooed parts of a map leading to a huge stash of gold.
- Let's Split Up, Gang: They decide to go their separate ways after escaping Abashiri, but promise to go to Hokkaido.
- Sorting Algorithm of Evil: The two first Abashiri convicts Sugimoto meet are incompetent crooks who don't even deserve a name. The third, Shiraishi, is competent in his line of work but is still a Butt-Monkey. Then come Hijikata Toshizou and Ushiyama Tatsuma, respectively a Living Legend and a The Juggernaut, whose fighting ability rivals Sugimoto's easily.
- Ax-Crazy: He is said to have hacked seven men to pieces. However, Noppera-Bou denies it vehemently, which makes sense since he isn't greedy at all but genuinely fights for the Ainus.
- Bald of Evil: Not a single strand left on that grotesque dome.
- Boom, Headshot!: He is killed by Ogata with a shot to the head.
- Can't Kill You, Still Need You: He is still alive because he knows the location of the treasure.
- Evil Cripple: One warden cut off the tendon of one of his legs, which didn't stop him from committing his nefarious plan.
- Facial Horror: He has a completely burned head and exposed teeth.

- A Good Way to Die: Nihei wants to die as prey for an animal meaner than he is, and sure enough he is killed by two Hokkaido Wolves.

- Fingore: Nihei gets several fingers chopped off during a fight but he doesn't mind it a lot. His shooting finger is still in place.

- Neck Snap: Performing one of these on someone in front of the police wasn't a good idea.

Kano IenagaFor Kano Ienaga, see Hijikata's group.
- Affectionate Nickname: Kiichirou calls Nakazawa "Princess".

- Aw, Look! They Really Do Love Each Other: Kiichirou and his lover Nakazawa Tatsuya spend their time bickering, and Nakazawa even tries to send him to his death because Kiichirou cheated on him once. It doesn't prevent Nakazawa of looking for Kiichirou's sword like a prized heirloom or Kiichirou to fight a bear to the death to save Nakazawa. Both die holding each other's hands.

- Do Not Go Gentle: Oh so very much. Choosing to fight a brown bear with a swordnote , paying no atention to little details like dying in the process, is one thing; making crude jokes about it almost with his dying breath is another; but anally raping the mauled bear with the sword as a finishing move takes "defiance" to a whole different level.Kiichirou: Congrats on losing your anal virginity.

She then uses her awl to stab the foramen magnum, the one opening of the skull that lets the spine through, and scramble their brains.

- Four Eyes, Zero Soul: He wears a pair of round spectacles.

- Bald of Awesome: His hair is cut very short, revealing the silhouette of his cranium.
- Bishie Sparkle: He often gets sparkles, although he is more of a Hunk than a Bishōnen.
- Blood Knight: He seeks and enjoys fistfights because he considers it his own form of expression. He's stated to have fought others since his youth which earned him a trip to Abashiri prison. In here he thrived, continuing to start other prison brawls just for the sake of it, and has crossed fist against Ushiyama of all people several times. Gansoku finally says that everyone time he hears the crowd surrounding his fights, it affirms who he is.
- Expy : One of "Britain's most violent inmate", the real life Michael Gordon Peterson (otherwise known as Charles Bronson), in his general appearance and love of brawling.
- Flat Character: His mindset is very simple as was his whole life, which can be synthesized into the simple sentence "Gansoku started brawls". He appears to offer a couple of action scenes and humorous lines and then disappears just as fast.
- Perpetual Smiler: He is almost always smiling.
- Specs of Awesome: Despite his round glasses, he's a burly muscled man who's tough enough to be a match for Ushiyama, provided Ushiyama doesn't get a judo hold on him. When he steps in the ring during a stenka session, his first punch throws Sugimoto several paces away, knocking him against the fence.
- Warrior Therapist: When fighting, he feels Sugimoto is angry and asks him why. When the young ex-soldier answers that he is angry at how useless he is to his loved ones, the runaway convict tells him to forgive himself as he recognizes Sugimoto's efforts.
- Worthy Opponent: As with Ushiyama, he shakes hands with Sugimoto once and it's enough for him to appreciate the soldier immediately, looking forward to their next fight.
Youichirou "The Manslayer"
- Assassins Are Always Betrayed: He was betrayed by his master to secure a position within the new government and thrown in prison.
- The Atoner: He threw away his life as a "beast", being an assassin for hire, to live among Ainus as a "human". Ainu means human, but Yoichirou mainly wanted to live a decent lifestyle for the remainder of his life.
- Badass Boast: He's ordinarily meek and soft-spoken, but when someone comes to really threaten his life, Youichirou shows some impressive bravado.Would-be avenger:This is revenge for my father. Pay for killing him with your life.Youichirou:Line up to die then. There's plenty of people who want to kill Youichirou the Manslayer.'
- Battlecry: Youichirou has the habit of screaming "Tenchu!" with every slash of a sword, signifying "Heaven's punishment!".
- Cool Old Guy: Youichirou is so old he's become senile. But his fighting capacity is still there as shown when he dispatches two bounty hunters with two quick slashes of an ax to their feet.

- You Killed My Father: Youichirou seems to have been at the receiving end of this line many times, as he was hired to kill specific important people, leaving their families ample opportunity to seek revenge on him.

- Firing One-Handed: He uses a Winchester rifle one-handed.
- Former Teen Rebel: Hijikata was an undisciplined brat who liked to hang out with women more than training at his dojo.
- A Handful for an Eye: During their fights, Hijikata secretly gathers some blood in his palm and tosses it at Inudou's eye, giving him a crucial opening.
- Heroes Prefer Swords: In an age full of guns, Hijikata is still using a sword.
- Historical Domain Character
- Hot-Blooded: Hijikata had a wild personality in his youth, earning him the nickname "Baragaki.", a play on the words "Ibara" meaning thorny and "Gaki" meaning kid.
- Katanas Are Just Better: he wields a katana (and a rifle), as befitting of a member of the Shinsengumi.
- Lawman Gone Bad: Hijikata was a Shinsengumi, which was an order of peacekeeping warriors. Not accounting for the Shinsengumi's fall from grace, Hijikata is now a prison escapee and little more than a gang leader with a vision.
- Living Legend: The vice-commander of a famous order of peacekeeping samurai.
- Old Soldier: A veteran who fights as well as he commands, using military tactics and swordsmanship to prevail in a shootout between two gangs.

- Weapon Twirling: He reloads his Winchester by twirling it.

- Badass Boast: "Go on then, and tell the other bears... the legend of Ushiyama the Undefeated."
- The Casanova: He has an insatiable lust.
- Charles Atlas Super Power: Can break limbs easily with his grip alone, and has used his judo skills against horses, bears and collapsing buildings.
- The Dragon: Hijikata's most trusted subordinate.
- Embarrassing Nickname: Asirpa calls him Professor Penis. It overlaps with Affectionate Nickname as the two became drinking buddies after both got drunk in a restaurant.
- Hard Head: Ushiyama has an abnormally thick skull, which can resist the slash of a sword.
- Heroic Sacrifice: When Tanigaki and Inkarmat are trapped beneath falling rubbles, and more threaten to fall on them, Ushiyama intervenes and supports a whole building so the couple can escape. Sweating from the effort, Ushiyama even utters some Famous Last Words to them.You guys...better live a happy life together, ya hear me?
- And then the rubbles overwhelms him. Of course, Ushiyama simply tosses everything asides and brushes his dusty suit. Although the moment really invokes this trope, it's not like he was really let some bricks kill him.
- The Juggernaut: In Chapter 33, Ushiyama pursues Shiraishi across the streets of Otaru. A small group of hostiles looking for a fight are just tossed away by his charge. Shiraishi making a huge pillar of (hard as stone) snow doesn't faze him, and he sweeps a horse on his way.
- Made of Iron: Ushiyama defies all laws of physics by shrugging off an explosion great enough to destroy a whole building then the subsequent falling debris.
- Only in It for the Money: While Hijikata has grandiose plans, Ushiyama only wants money to spend.
- Pragmatic Villainy: Proposes a truce between him and Hijikata, saying that there's no need to kill each since they are free to copy the map on their tattoos anyway.
- Red Baron: "The Undefeated".
- Strong and Skilled: He is a trained judoka, so he is as skilled at using his strength as he is strong.
- Training from Hell: 10 hours of daily training at least, for ten years. That explains his freakish strength. Ushiyama begins with 1000 uchikomi every day then carries on to the real training.

- Cool Old Guy: In Chapter 59, Nagakura demonstrates that he hasn't lost his edge by swiftly disposing of five armed men with a saber.
- Former Teen Rebel: We learn that alongside Hijikata, Nagakura was undisciplined, and fooled around with women. A great contrast to the dignified old man of the story.
Superior Private Ogata Hyakunosuke
Voiced by: Kenjiro Tsuda (Japanese), Orion Pitts (English)
- Ambiguous Disorder: Under his Mask of Sanity, Ogata has deep underlying issues. As a child, he poisoned his mother hoping that his absent father would come to the funeral. He also killed his legitimate half-brother in an attempt to win attention, and when that didn't work, he murdered his father himself. Ogata also expressed that his particular upbringing without parents that love each other was responsible for his condition, and considers his half brother normal because he had parents that did.
- Animal Motifs: Cats, specifically the wildcat.
- Bastard Bastard: He is revealed to be the child of Lieutenant General Hanazawa and one of his mistresses.
- Boom, Headshot!: Averted when pursued by Tsurumi's soldiers. He deliberately shoots less important body parts to wound them because the wounded slows down a group and reduces morale. He shoots others in the head when convenient, however.
- Cain and Abel: The Cain to his legitimate half-brother. Ogata shot him in the head at 203 Hill.
- Character Tic: He's regularly trying to fix his Idiot Hair.
- Cold Sniper: Ogata is a great shot with his Arisaka rifle and is exploiting many sniper techniques such as two-man sniper team before their actual invention. He's also aloof, cold, and no-nonsense when sniping and in general. A shining and really creepy example of this trope is when he snipes Noppera-Bou and shoots Sugimoto in the head. After the shocking panel where a bullet goes through Sugimoto's skull, we see Ogata in the watchtower silently reloading. No Evil Gloating, no Bond One-Liner, not even the slightest expression on his face.
- Disarm, Disassemble, Destroy: He is proficient enough to be able to disassemble a rifle in the middle of a Gun Struggle.
- Dying Clue: Downplayed, Ogata merely faints before he can write the entirety of Sugimoto's name and nickname.
- Dying Smirk: Gives one to Aspira after she accidentally shoots him in the eye with a poisoned arrow believing he made her into a killer against her will, but averted when Sugimoto quickly saves his life.
- Even Evil Has Loved Ones: He is fond of his grandmother. Averted when he was revealed to have killed most of his immediate family.
- Even Evil Has Standards: He breaks out in a sweat with disbelief upon witnessing Shiton raping a bear.
- Eye Scream: Asirpa shoots an Ainu arrow through his eye. Sugimoto saves him from the poison by carving the eye out with a pocket knife.
- Faux Affably Evil: Amicable and polite when interacting with others while also being consistently smug, condescending and insincere.
- Give Me a Reason: He'd rather not kill everyone in the Ainu village if he didn't have to, but would if Tanigaki did something stupid.
- Good Scars, Evil Scars: A jaw-surgery scars on each cheek.
- Idiot Hair: Ogata has a wild strand of hair hanging on the side of the head.
- Improbable Aiming Skills: Can hit something as small as a binocular 300 meters away with an Arisaka rifle.
- Last-Name Basis: Everyone calls him by his surname.
- Long-Range Fighter: Downplayed. Ogata is a Cold Sniper with Improbable Aiming Skills, and he's able to (more or less) hold his ground against Sugimoto in their first confrontation; yet close-range combat is not his strongest point, as he is also shown to not be able to stand up to fellow 7th Division soldiers at close quarter combat.
- Know When to Fold 'Em: When he gets his arm broken, he flees.
- Not in This for Your Revolution: Ogata isn't a native of Hokkaido and has no interest in rebelling.
- Not So Above It All: Ogata hides it, but during his travel with Asirpa, he is subtly influenced by her happy demeanor. When Asirpa tells him that he can't catch any woodcock with his rifle, he takes it as a challenge and is proud to see he's actually caught more than Asirpa.
- Not So Stoic: He's usually a Cold Sniper who rarely shows any emotion, but he breaks out in a sweat with disbelief upon witnessing Shiton raping a bear.
- Perma-Stubble: Ogata gains one after being absent a while.
- Self-Made Orphan: Ogata, already little nuts in his childhood, poisoned his mother so that his father would come to the funeral out of love for his mistress. He then killed his father, and covered it up as seppuku at Tsurumi's suggestion.
- The Starscream: He plans to betray Tsurumi, but more out of pragmatism since he never felt loyal to him.
- Wake-Up Call Boss: The first soldier of the 7th Division seen, and makes the reader realize how dangerous they are.

- All There in the Manual: Q&A mentions on Twitter that her former name is Chikanobu.
- Aloof Dark-Haired Girl: She has Raven Hair, Ivory Skin, and seems aloof due to seemingly wanting to distance from her customers. She is described as a beautiful Japanese woman who wears western clothes.
- Beauty Mark: Has one on the right cheek.
- Bondage Is Bad: Heavily implied, as one flashback shows her with a tengu mask whose nose looks like a dildo beside a tied victim.
- Cannibalism Super Power: Ienaga invokes this by claiming that when one's particular body part is ill, they should eat the same body part to heal it.
- Dark Chick: She becomes this after joining with Hijikata's Group.
- False Widow: People in the area are skeptical as the previous owners were a childless elderly couple. She then claims her "husband" was an unwanted child, but when he died fighting in the war, and his parents died, Ienaga who was like a daughter to them inherited the place. People actually believe the story despite not having seen her in the area before.
- First-Episode Twist: Her true self and motives are shown at the end of her introductory chapter.
- Heroic Sacrifice: Saves Tanigaki and Inkarmat from being shot by injecting Tsukishima with a strong sedative and gets fatally shot in return.
- I'm a Humanitarian: Ienaga eats people for "medicinal purposes".
- Keigo: She always speaks in formal Japanese.
- Mad Doctor: Ienaga used to be a doctor and transferred her patients' blood into herself, sometimes even eating them. Her surgical skills actually do come in handy offscreen, when she performs a lifesaving brain surgery on Sugimoto, who was shot in the head by Ogata. Even though no doctor in Japan is supposedly able to do it, her torture hobby has given her many occasions to practice.
- Not Quite Dead: Thought to have perished in the explosion of the Sapporo World Hotel, Ushiyama quickly reveals to Shiraishi that he's saved Ienaga.
- Older Than They Look: Ienaga is at least 60. Her "medicine", as barbaric as it is, seems to work.
- Prim and Proper Bun: She wears a neat high bun, with the demeanor of a Yamato Nadeshiko. It's mostly a ruse as she's actually a Serial Killer posing as a False Widow to get people to trust her so she can lure them into her hotel to eat them.
- Raven Hair, Ivory Skin: She has fair skin to contrast with her black hair and Western dress. She is described in-story as a beautiful Japanese woman.
- Romancing the Widow: Ushiyama tries this.
- Transgender: She's a trans woman, having been designated male at birth and originally named Chikanobu.
- Yamato Nadeshiko: She has Raven Hair, Ivory Skin, and formal manners, though she notably wears a dress instead of traditional Japanese clothing. She's ultimately a subversion, since it's all an act to hide how she's really a Mad Doctor who eats parts of her own patients.
- Aluminum Christmas Trees: Toni's human echolocation skills are a real thing.
- Blind Weapon Master: Toni is blind, but is still a very good shot with his pistol.
- Cool Guns: Carries a "broomhandle" Mauser pistol with detachable holster/shoulder stock. Extra cool points for also carrying the gun's full rig of accessories.
- Disability Superpower: To alleviate blindness, Toni relies on a very sharp sense of hearing.
- Even Evil Has Standards: Toni Anji may be a robber who even attacks innocent Ainu villages, but he makes a point to avoid killing anyone who wasn't involved with Abashiri and Inudou.
- Expy: Toni Anji seems to be inspired by Tony Anthony, an American Western actor who notably played a blind cowboy in a movie.
- Improbable Aiming Skills: Toni is able to hit a lamp despite his blindness by using echolocation.
- Handicapped Badass: Toni is blind, but he's still a rather good shot with his automatic pistol and can fight toe to toe against Sugimoto too.
- Tap on the Head: Toni is knocked out by Inudou when the warden hits him with a metal ball right on the forehead. Subverted, as he almost dies because of it.
The Hokkaido 7th Division
- Anti-Villain: Most of the soldiers aren't evil per se. They plan to betray their government but only after a lot of mistreatment from their superior's part and the lack of reward for their sacrifices. In fact, they are polite toward civilians and can even lend help to them, as seen when a disguised Kiroranke asks them to help him clear rubbles and they accept; moreover they were fooled by Tsurumi into thinking their commander committed seppuku because of the treatment. That doesn't mean that they don't obey orders to kill, and if some poor schmuck is given a gun and is pitted against them, they don't think twice before shooting.
- Badass Army: Overlaps with Elite Army. They were at the forefront of the Russo-Japanese War and are tasked with protecting the northern territories of Japan
- Back for the Dead: Inverted; several soldiers who get gruesomely Killed Off for Real in an early episode are featured in a much later flashback.
- Determinator: Whoever fails to score an instantly fatal wound on one of them quickly regrets it, as even serious stab, gouge or bullet wounds will only make them more determined to kill you.
- Dude, Where's My Respect?: The 7th Division grew dissatisfied with the lack of gratitude from the Japanese government. The humiliations culminated in their Commander Hanazawa committing seppuku. Tsurumi channeled the resentment and pushed them to secretly revolt against their government.
- Elite Mook: A foot soldier is an already tough opponent. Although they aren't as famous as Sugimoto, each of the 7th Division soldiers is a hardened veteran who has also survived the war. More than two of them is enough to beat Sugimoto.
- Elites Are More Glamorous: Sugimoto's main enemy had to be the most elite military unit of Hokkaido, of course.
- Empty Eyes: All soldiers from the Division are drawn with big black dots for pupils, making them look creepy.
- Fan Boy: While not all of them go that far, a distressingly high number of soldiers take their devotion to First Lieutenant Tsurumi a bit too far. A large bit.
- Last-Name Basis: Every member of the 7th Division are called by their surnames. Tokushirou Tsurumi, Hajime Tsukishima, and Otonoshin Koito don't reveal their first names until much later. Meanwhile, Usami has yet to reveal his first name.
- Made of Iron: Shockingly and consistently resistant to pain and injuries that would disable a normal person, an extreme example is a soldier killing a bear after it ripped his face off, including an eye ball and his jaw.
- Military Coup: Part of the 7th Division wants to secede from Japan and take over Hokkaido.
- More Dakka: Tsurumi has been buying all kinds of weapons in preparation for his war. Among those used by the 7th Division are several Hotchkiss and Nambu machine guns, and even several destroyers, with full artillery bombardment, to break Abashiri Prison's walls.
- Nice Hat: They all wear the Imperial Japanese Army cap.
- Red Baron: Among the populace, the 7th Division is also respectfully referred as the "Hokuchin(北進) Unit", which means "Defenders of the North", in homage to their performance during the Russo-Japanese War.
First Lieutenant Tokushirou Tsurumi
Voiced by: Hochu Otsuka (Japanese), David Wald (English)
- A Father to His Men: Strangely, yes. Not so when they turn against him.
- Awesomeness by Analysis: Tsurumi is an intelligence officer, and deduces pretty quickly a Wounded Gazelle Gambit from Sugimoto's part.
- When one of his superiors is announcing that he intends to fire him, Tsurumi bites his fingers off then has his men shoot the guy.
- His massacre of the staff and prisoners of Abashiri prison is done with utter glee and much laughing.
- Cool Guns: A Borchardt C-93.
- Badass Boast: I am your shinigami. Your life is a candle, and I can blow it out any time I choose.
- Big Bad Ensemble: Alongside Hijikata Toshizou.
- Establishing Character Moment: He bites off an angry superior's fingers but justifies himself with all the calm in the world. He then has that same officer shot and recites how the 7th Division was wronged, stating that their war isn't over.
- Firing in the Air a Lot: He introduces himself to Sugimoto like this to stop his men from killing him.
- Flower Motifs: He often has the background break out in white poppies.
- Genuine Human Hide: He wears the skin of the convicts he's caught on himself.
- Good Hair, Evil Hair: In case you thought he might be a good guy, just like at his handlebar mustache and goatee.
- Good Scars, Evil Scars: A huge scar is visible around his eyes.
- Good Weapon, Evil Weapon: An evil looking Borchardt C-93 pistol.
- Hair-Trigger Temper: He admits to having trouble controlling himself since he's got a piece of shrapnel in the head. He mixes that with Tranquil Fury.
- Holding the Floor: When telling Tsukishima that he's taking Tsukishima out of death row to go with him because of his fluency in Russian, he talks and talks and talks and talks... about Tsukishima's linguistic skills and their usefulness for the country, at some length, to keep Tsukishima from objecting that he doesn't speak a word of Russian.
- The Hard Hat: He has a huge metal plate on the forehead. Cranial fluid still oozes from time to time.
- Hidden Depths: Tsurumi is introduced as a mad officer, but he can also play the piano.
- The Lost Lenore: Before the war, he was a deep undercover spy in Russia. He married a Russian woman, was actually in love with his wife and had a child. When his cover was blown because of someone else's failure and the secret police came for him, his wife and child were killed by a stray bullet in the ensuing firefight. This was the start of his deep disenchantment with the Japanese government.
- Manipulative Bastard: Tsurumi is really a smooth-talker. He has manipulated his whole entourage and unit to further his plans, murdering his superior and pinning the responsibility on the government to goad his soldiers to revolt; Ogata notes how Tsurumi has been lying through his teeth about him being a worthy son to his father (said murdered commander); and he has lied to Tsukishima to recruit him.
- Outliving One's Offspring: When his cover was blown because of someone else's failure and the secret police came for him, his wife and child were killed by a stray bullet in the ensuing firefight.
- Riches to Rags: His family was wealthy but fell on hard times.
- Slasher Smile: Tsurumi sports his bloodthirsty grin a lot of the time.
- Sociopathic Soldier: Was once a worthy officer in the Army, receiving a piece of shrapnel in the head and the poor state his unit's been left in made him bitter and violent.
- Sweet Tooth: Tsurumi is seldom seen without some sugary dangers.
- Visionary Villain: Tsurumi's end game is to take over Hokkaido and have a haven for the veterans of his Division.
- We Can Rule Together: Tsurumi proposes Sugimoto to join his military coup, offering sound reasons that should resonate with a veteran like him. But Sugimoto refuses anyway.
- Well-Intentioned Extremist: Wanting his men to receive their just compensation? Admirable. Take over the island he's supposed to protect and kill anyone in his path? Not so admirable anymore.

- Those Two Bad Guys: Always seen and work together until Youhei died.
Sergeant Hajime Tsukishima
Voiced by: Eiji Takemoto(Japanese), Quinn Angell (English)
- Captain Smooth and Sergeant Rough: The Sergeant side. While not exactly "rough", he is blunt, stoic, and comparatively so when Tsurumi is around. None of the other members of the 7th fawn after him like they do with Tsurumi, either.
- Chekhov's Skill: A rare case of it being an Invoked Trope, as part of Tsurumi's plan to save his life from death row. Tsurumi (headed to Russia to act as an intelligence oficer) stated (at quite some length) that his trusted subordinate and talented interpreter Tsukishima's high skill and fluency in Russian made him vital for the country, so he was taking Tsukishima out of death row to go with him. Tsukishima knew not a word of Russian, and was told to learn it right away.Tsurumi: Tsukishima... you're fluent in Russian, right?
Tsukishima:[surprised] Huh? No sir... I can't speak Russian at all...
Tsurumi: [long monologue over multiple panels] Soon there will a war between Japan and Russia. Yet we don't have nearly enough Russian interpreters. A man with your level of ability in Russian will surely be treated with compassion. After all, our country's very existence is on the line. (...) I'll be headed to Russia as an intelligence officer. You're my trusted subordinate and a talented interpreter, so I'll be taking you along.
Tsukishima: Sir, I can't speak a word of Russian! And I'm on death row!
Tsurumi: THEN YOU'D BETTER STUDY LIKE YOUR LIFE DEPENDS ON IT!
- Childhood Friend Romance: Tsukishima was a friend with a girl, who was the one who called him by his name "Hajime" while everyone would use insults. The friendship eventually became a romance, Tsukishima and her agreeing to marry each other after the Sino-Japanese war.
- Cunning Linguist: Tsukishima is fluent in Russian, which made him indispensable during the Russo-Japanese war. When he and Sugimoto go after Asirpa, his Russian helps to ease the search for her in Sakhalin.
- Empty Eyes: Averted, being the only 7th Division member of Tsurumi's circle to not have them, as befitting his Only Sane Man status.
- Facial Markings: Tsukishima has two lines on his face resembling under eye wrinkles.
- Genius Bruiser: He was able to learn Russian when in death row to make himself indispensable for the war, and in the unknown but necessarily short time between Tsurumi ordering Tsukishima to learn Russian right away, and Tsurumi's request to free Tsukishima being granted.
- Hidden Depths: It's shown in Chapter 140 that besides his career as a soldier, Tsukishima is also fluent in Russian. Chapter 149 shows he learned it in a shockingly short time.
- The Lost Lenore: Tsukishima was in love with an unnamed girl whom he promised to marry after the Sino-Japanese war he went to. However when he returned to his hometown, he discovered that she came to believe that he dies and killed herself (however, he never saw her corpse). Subverted when he met Tsurumi, who discovered it was all a ploy to persuade the girl to move out to Tokyo and said girl even sent him a lock of hair. Then Double Subverted when he discovers that his love was really dead all along and Tsurumi lied to him. Triple subverted when he's told Tsurumi faked the girl's death to help Tsukishima off death row. Zigzagged to we don't even keep track of the number when it's heavily implied that the person who told him was working for Tsurumi, to begin with. Frankly, nobody really knows if she's alive or not.
- Motivational Lie: Was on the receiving end of this, when Tsurumi told him that the girl he loved was alive, pushing him to learn Russian and avoid the death sentence. He later learns that Tsurumi indeed lied, and confronts him, furious.
- My Master, Right or Wrong: Sure, he is aware that Tsurumi is at the very least, unstable. However, he's also a loyal soldier and obeys his every order. Chapter 149 shows that he is aware that Tsurumi is a Manipulative Bastard.
- Only Sane Man: Among his quirky and downright psychopathic colleagues, Tsukishima stands out by being a model of professionalism and overall normalcy.
- Patricide: Tsukishima already hated his father, but when the latter spread rumors about him being dead, leading to the suicide of Tsukishima's girlfriend, he beats him to death.
- The Reliable One: Tsukishima does what he's told, is loyal to Tsurumi and condemns traitors, and is the most competent subordinate in the 7th.
- Sins of Our Fathers: Tsukishima was ostracized and bullied as a child because of his father. Although nothing is specified, Tsukishima was called a murderer's son.
- Straight Man: His Only Sane Man status overlaps with The Comically Serious whenever he witnesses some of his colleague's hijinks, with a deadpan but clearly annoyed expression on his face. The most annoying out of them all for Tsukishima seems to be Koito.
- Trading Bars for Stripes: Although he was already a soldier, Tsukishima briefly went on death row for murdering his father. However, thanks to/because of Tsurumi lying about Tsukishima being fluent in Russian, and Tsukishima's efforts to actually learn Russian; he became part of Tsurumi's staff during the Russo-Japanese War.
Second Lieutnant Otonoshin Koito
Voiced by: Katsuyuki Konishi(Japanese), Daman Mills (English)
- Ambiguously Brown: Koito is noticeably tan for a Japanese, making him stand out among characters.
- Animal Motifs: Koito is subtly compared to a monkey.
- Attack! Attack! Attack!: Koito uses the Jigen-Ryu sword style, which is so aggressive is it said that the Shinsengumi commander only advised dodging the first blow of its practitioners. Trying to block it results in the swordsman smashing the sword into his opponent's forehead.
- Calling Your Attacks: Played for Laughs; The Jigen-ryu style first blow is also famous for his specific and impressive kiai, called Enkyō (monkey's scream), that goes with it. He often uses it as his Catchphrase very often. Not just when he should (when using his first blow), he also uses it whenever he is surprised, excited, confused, or simply in any situation where him "screaming like a monkey" would be funny.
- Genius Bruiser: Koito is a force to be reckoned with, as he's really fast, agile and is a seasoned sword practitioner with an aggressive style. Upper-Class Twit moments aside, he's quick to formulate simple plans to outsmart enemies, like when he tricks Suzukawa Kiyohiro into giving away his disguise or keeps shooting Keiichirou while pursuing him just to give away his position and trajectory to Tsurumi.
- The Gift: Parodied during the Circus Arc. He's got an exceptional talent for acrobatics, in a circus in which 90% of the shows are acrobatics. Sugimoto develops a petty rivalry over this and tries to outdo Koito with a magic trick.
- Hair Color Dissonance: Is meant to have black hair as a Japanese but has dark purple hair in the anime and dark blue hair on the cover for Volume 16 of the manga.
- Japanese Dialects: Koito speaks the Satsuma dialect, a near incomprehensible dialect to most Japanese.
- Ooh, Me Accent's Slipping: Whenever he loses his calm, and somehow whenever he wants to talk to Tsurumi, Koito slips into his Satsuma dialect.
- Precious Photo: Has one of his idol First Lieutenant Tsurumi. In fact, he has several of them and has glued his face to anyone who's shared photography with Tsurumi.
- Silly Reason for War: During the Yamada's show arc, Koito's gift in acrobatics threaten to overshadow Sugimoto's harakiri's trick (the whole reason of them being in the show, to begin with). A subplot develops with Koito refusing to tone down his performance and Sugimoto trying to outdo and eventually ruin Koito's show.
- Sycophantic Servant: Koito is his First Lieutenant's number one fan. He saved his life after all.
- Upper-Class Twit: Downplayed. When he's not fighting, Koito proves to be rather out of touch with reality. He expects someone to carry his six large suitcases (one of which was occupied by two stowaways) in Sakhalin, and unlike his wiser companions, underestimates a wolverine which just took down a bear because of its size.
- Weapon of Choice: Koito prefers to use swords, unlike many of his fellow soldiers.
Superior Private Usami
- Beauty Mark: Usami has two beauty marks on both of the cheeks.
- Creepy Doll: His (7th division-standard) Empty Eyes plus his BeautyMarks give him the a very creepy and doll-like appearance.
- Facial Markings: When Tsurumi drew running stick men in his face using his moles as heads, Usami had the drawing tattooed. Kadokura is totally freaked out by this.
- I Am Not Left-Handed: When Usami is found to be a spy and then tricked into going into a prison pigsty unarmed, he shows that even unarmed he can kill two unruly prisoners by stealing their hammers and beating them to death on the spot. Kadokura, who stole his saber and intended that he die at the hands of prisoners, wisely decides not to attempt to kill him.
- Sycophantic Servant: Just like Koito, Usami is practically in love with Tsurumi.
Voiced by: Yuuma Uchida (Japanese), Brandon McInnis (English)
- Abusive Parents: His mother apparently castrated him at one point. His father was not abusive, but he was murdered for it.
- Adorkable: Awkward, but really endearing in his own way. His morbid quirks don't make him violent, so he's infinitely more sympathetic than the average weirdo in the series.
- Ax-Crazy: Averted! Yasaku, despite being mad, only uses the skin from already dead people, and doesn't want to participate in fights.
- Bunny-Ears Lawyer: Sure he may have an obsession with creating clothes with human skin or outright play with corpses, but he sure knows his business when taxidermy or skin tanning is concerned.
- Calling the Old Man Out: Yasaku takes the courage to talk ack to his mother for everything abuse he received from her.
- Cool Mask: A creepy but awesome mask made out of several hands and ears (their shape is visible).
- Cute and Psycho: A good looking fellow, but also a crazy one.
- The Dog Bites Back: Years of abuse pushed Yasaku to murder his mother (figuratively speaking, he, in fact, murders a voice in his head).
- Expy: Yasaku takes from many famous serial killers, such as Ed Gein, Leatherface, or Norman Bates.
- Facial Markings: Two vertical lines going from under his eyes are visible.
- Genuine Human Hide: Yasaku creates clothes out of corpses' skins.
- Gollum Made Me Do It: His "mother"'s voice pushes him to murder. However, Edogai never acted on these impulses.
- Hearing Voices: Yasaku can still hear the voice of his parents and many others and has conversations with them. Tsurumi's influence has at least suppressed his mother's voice.
- Heroic Sacrifice: When a mineshaft Edogai's in becomes filled with smoke, he tells Tsukishima to flee with the skins, sacrificing himself to Tsurumi's cause.
- Matricide: Figuratively speaking. Tsurumi pushed him to shoot her corpse, so he doesn't hear her voice anymore.
- My Beloved Smother: Yasaku's mother was so controlling (and crazy) she killed Yasaku's father for taking his side and castrated Yasaku when he became "too much like his father". All for his good of course. Even after she died, Yasaku kept hearing her domineering voice.
- Punny Name: His name "Edogai" is a play on "Ed Gein," a famous killer.
- Villainous Friendship: Yasaku and Tsurumi become excellent friends over a mutual interest in human skin.
- Carry a Big Stick: A stick called sutu is used to punish thieves and murderers.
- Fingore: Sakhalin Ainus punish thieves by chopping a fingertip for each offense and moving down the fingers if need be.
- Foreign Queasine: The raw brain is a delicacy for them.
- Green Aesop: Respect nature.
- Guardian Entity: Ainus believe that a spirit called a turenpe protects each of them and thank them with offerings.
- Noble Savage: They live off of nature and know to respect her. They are also friendly to Japanese despite being discriminated.
- Only One Name: Unlike the Japanese, the Ainu have no surname.
- Oral Tradition: The Ainu don't have a writing system and pass out their stories orally.
- Our Gods Are Different: Everything is a god, and the gods gifted the Ainu with what they have.
- Poison Is Evil: Averted, Ainu are Noble Savages and use poisoned arrows to kill their prey rapidly. Each clan has its secret recipe.
- Prophecies Are Always Right: Traditionally, Ainu takes divination seriously and believe dreams can show them the future. These beliefs aren't accepted by more modern Ainu like Asirpa.
- Thou Shalt Not Kill: Killing someone is taboo, and a man-killing animal is considered to be an evil god, unfit for consumption. However, several Ainu women whose village was overtaken by a group of prison escapee do use lethal force to fight them off.
- Trap Master: Part of their hunting skill.
- Tribal Facepaint: Women traditionally tattoo their mouths and cheeks to signify that they are old enough to be married.
- Unfortunate Name: Subverted, to ward off evil spirits, infants will have disgusting-sounding names until they are six years old.
- Worthless Yellow Rocks: The Ainu have hoarded gold for generations without actually making use of it. In fact, it's less than worthless since collecting gold pollutes the rivers in which they fish.
Voiced by: Hiroki Tochi (Japanese), Barry Yandell (English)
- Abusive Parents: Zigzagged. He put Asirpa through Training from Hell with the secret intent of grooming her into becoming a freedom fighter waging war against the Japanese government for the Ainu. Judging from what is shown in the series, it involved telling her to hunt a bear alone when she was seven or younger. Despite this, he was an otherwise loving and supporting father and it's implied that he did what he did because he trusted her exceptional abilities as a hunter and a survivalist, rather than abusing her for the kicks.
- Badass Beard: He had a rather thick beard; which smelled according to Asirpa.
- Badass Native: Asirpa described him as one of the bravest bear hunters of his people, having one day crawled into a bear den to kill it with one poisoned arrow.
- Bitch in Sheep's Clothing: He is described and remembered by Asirpa as a loving father, as well as a skilled hunter. He was once a ruthless terrorist in Russia and, after Asirpa was born, had been secretly grooming her into becoming a freedom fighter waging war against the Japanese government for the Ainu, using hunting and survival training as a pretext.
- Broken Pedestal: Asirpa is shaken to learn that he is really the Noppera-Bou and cries.
- Chick Magnet: According to Asirpa, Wilk was popular with the ladies because of his excellent craftsmanship; "Ainu men craft a makiri (short sword) and give it to the woman they like. She looks at the craftsmanship and decides how good of a provider that man is." In addition, not only it's implied that Inkarmat had a Precocious Crush on him as a child, but Sophia, a Russian noblewoman, has unrequited feelings for him.
- The Faceless: Although he's spoken of a lot, the manga has yet to properly show his face. Only glimpses of it are shown. His full (old) face is then revealed in chapter 137.
- Follow in My Footsteps: Wilk had been taking his daughter alongside him on hunts to teach her how to hunt although Ainu women typically stay at their village. The trope takes on a darker meaning when it's revealed that he did that to eventually turn her into a freedom fighter waging war against the Japanese government for the Ainu.
- Deceased Parents Are the Best: Asirpa has nothing but fond memories of her late father and praises his ability as a hunter. Subverted with The Reveal that he is still alive as Noppera-bo and his confession to Sugimoto that he had been secretly grooming her into becoming a freedom fighter waging war against the Japanese government for the Ainu, using hunting and survival training as a pretext.
- Going Native: Inkarmat claims that Wilk was Christian because of his Polish descent, but that he embraced the Ainu beliefs and customs wholeheartedly.
- Good Eyes, Evil Eyes: He had blue round eyes. He is described and remembered by Asirpa as a loving father, as well as a skilled hunter. Subverted because he was once a ruthless terrorist in Russia and, after Asirpa was born, had been secretly grooming her into becoming a freedom fighter waging war against the Japanese government for the Ainu, using hunting and survival training as a pretext.
- Good Scars, Evil Scars: Wilk had a pretty large scar on his head earned during his fighting against the Russians. It notably resembles Sugimoto's, and Asirpa is unconsciously fond of Sugimoto's current face for that, even trying to avoid further scars on the latter.
- I Have Many Names: Wilk is his birth name, meaning "wolf" in Polish. When visiting Kouichi Hasegawa, he took on the name of Grigori to hide his identity as a Bomb Throwing Anarchist. When he told his wife about how he got his name, she gave him the secret name, Horkew Oskoni, meaning "to catch up to the wolves" in Ainu. When he was thrown in Abashiri Prison and lost his facial skin to torture, he was given the nickname Noppera-Bou, which is the name of a traditional faceless yokai.
- Manly Men Can Hunt: Wilk was an excellent hunter, and one of the few people to have killed bears alone. Even Sugimoto didn't do that.
- Meaningful Name: He was named by his father after the Polish word for "wolf" because he carried around a pelt of a dead wolf out of desire to become like the animals he considered pragmatic.
- Mixed Ancestry: He is the son of a Polish man and his Sakhalin Ainu wife.
- Posthumous Character: He is deceased by the time Sugimoto and Asirpa meet. Except, he was alive and was Noppera-Bou all along.
- Pure Is Not Good: When Asirpa asks Sofia what Wilk was like, Sofia answers that he was pure and beautiful, possibly referring to the fact that he helped assassinate Tsar Alexander II out of dedication to his cause.
- Sharp-Dressed Man: He used to wear a white shirt and a black jacket before replacing them with a customary Hokkaido Ainu clothing.
- Significant Wardrobe Shift: As a child, he wore a tetarape, a type of Ainu clothing made by the Sakhalin Ainu using urtica thunbergiana. As an adult, he used to wear a white shirt and a black jacket before replacing them with a customary Hokkaido Ainu clothing. As Noppera-Bou, he wears a prison uniform.
- Spell My Name with an "S": His name sometimes has incorrectly been spelled "Uiluk".
- Strong Family Resemblance: He looks like his daughter, Asirpa, with his black hair and round eyes.
- Used to Be a Sweet Kid: He used to be an adorable and innocent child. However, as an adult, he had become a Well-Intentioned Extremist fighting for the minorities against their oppressors through morally questionable methods.
- Two Aliases, One Character: He and Noppera-Bou are one and the same.
- Well-Intentioned Extremist: Wilk was partisan fighting for his people against the Russians. In Hokkaido, he decided to fight for the Ainus, gathering gold to eventually finance a revolt. His extremism went as far as practically training Asirpa like a Child Soldier so she could one day fight for the Ainus too, which Sugimoto finds unacceptable although he too thinks that the Ainu deserve their independence.
- "X" Marks the Hero: He had a cross-shaped scar across his forehead and down his left eye to the cheek. Subverted because he was once a ruthless terrorist in Russia and, after Asirpa was born, had been secretly grooming her into becoming a freedom fighter waging war against the Japanese government for the Ainu, using hunting and survival training as a pretext.

Voiced by: Miyuki Ichijou (Japanese), Jessica Cavanagh (English)

- Facial Markings: She bears the biggest tattoo around her lips because her husband was the most important man in her village.
- Language Barrier: Whatever Huci says is entirely in Ainu, and all the Japanese simply can't understand her clearly, although Sugimoto did guess what she meant one time about keeping an eye on Asirpa.
- Miniature Senior Citizen: She's even shorter than Asirpa.
- No Guy Wants an Amazon: Firmly believes this, and is concerned by Asirpa's lack of skill in typically female occupations such as weaving.

- Shipper on Deck: She wants Asirpa to marry Sugimoto, knowing Asirpa cannot be the wife of any Ainu because of her lack of skill in typically female occupations.
