Self proclaimed "World's Greatest Thief," Dororo first follows Hyakkimaru in order to eventually steal Hyakkimaru's sword in the original manga. In the 2019 anime, Dororo follows Hyakkimaru out of curiosity.
- Adaptational Attractiveness: Most adaptations make Dororo much older, and in the process much more visibly feminine along the way. When Dororo is kept as a child, the character design often makes the kid look more conventionally cute instead of scrappy.
- Adaptational Badass: The movies and game give Dororo a better fighting chance, allowing the kid to stand on the same ground as Hyakkimaru.
- Adaptational Nice Guy: In the 2019 anime adaptation, most of Dororo's reckless and Hot-Blooded tendencies are removed and he is far kinder and more worldy than the manga version, often acting as a genuine caretaker for Hyakkimaru who struggles with anything other than demon-slaying.
- Badass and Child Duo: The Child to Hyakkimaru's Badass, at least in the tellings that keep Dororo a child. Though the kid is not without spunk, however.
- Battle Couple: Eventually with Hyakkimaru in Blood Will Tell.
- The Caretaker: In the 2019 version. Being blind, deaf and lacking in social skills, Hyakkimaru can't fully take care of himself outside of hunting, so when Dororo joins him the kid basically acts as his eyes and ears, often feeding him and keeping him out of danger as well. A far cry from the Protectorate Dororo was in the original.
- Character Title: The one and only.
- Deceased Parents Are the Best: We see a flashback of Dororo's parents in episode 9 of the 2019 version and a flashback in the manga. His father was a bandit that was dedicated to attacking Samurai that took advantage of farmers like he used to be; while his mother did everything in her power to keep Dororo alive, eventually dying from exhaustion and malnourishment.
- Does Not Like Shoes: Never wears sandals, or any kind of footwear for that matter. Not unless ankle wraps count.
- Establishing Character Moment: Dororo's first scene has them trying to sell goods from a group of bandits that they stole from, before easily outmaneuvering them and running away. Later, they come across a hungry dog, and while Dororo does warm up to the creature, they tell them that they can't give them food or how else will they learn how to survive? This highlights Dororo's thievery skills, love for money, but also that they do have a warm heart deep down and only want to survive in this hard world.
- Hot-Blooded: Runs on this. Not so much in the 2019 series.
- Large Ham: Has a fondness for Chewing the Scenery. See Mouthy Kid.
- Made of Iron: Dororo can take one hell of a beating, and then walk it off like a boss.
- Make Me Wanna Shout: Dororo can apparently cause enemies to pass out simply by yelling loud enough. The kid does this twice in volume 2 of the manga, calling it a "secret move".
- He also has this move in Blood Will Tell, but only when he's possessed by the sword 'Nihil' (a.k.a. "Dragon Brood") or is low on life.
- Meaningful Name: "Dororo" どろろ is a corruption of "dorobō" どろぼう, which means "thief".
- Fun fact: According to trivia about his childhood, Tezuka's friends couldn't pronounce 'dorobo' correctly. This mispronunciation gave him the name of the series.
- Morality Chain: He is there to make sure Hyakkimaru doesn't become the same as the demons he fights.
- Mouthy Kid: He avoids becoming a complete Bratty Half-Pint by A) actually being as good a thief as he thinks he is, and B) being lively and energetic in a setting where that's in genuine danger of dying out.
- Opposite-Sex Clone: Her true purpose in Blood Will Tell, being made out of Hyakkimaru's missing parts.
- Only in It for the Money: Most of the time when someone requires Hyakkimaru's assistance to take care of a demon, Dororo is only too glad to offer Hyakkimaru's help, for a price.
- Please Don't Leave Me: In episode 9 Dororo catches an illness, a kind nun lets Dororo sleep in her monastery. He wakes up as Hyakkimaru is out getting water and freaks out that Hyakkimaru left in his sleep.
- Precocious Crush: In the series where Dororo is still a child, the kid is implied to have a small crush on Hyakkimaru. You see it with Dororo being embarrassed when naked around Hyakkimaru, and blushing when the latter calls the kid "cute" after he gets his sight back.
- Raised as the Opposite Gender: Dororo is a girl, but wasn't even aware of it. His parents raised him as a boy that way and didn't tell him otherwise. Apparently not the case in the 2019 adapation though.
- Supporting Protagonist: While Dororo is the originator of the manga's title and the kid is a main character, ultimately the primary mover of the story is Hyakkimaru and his quest to get his body back.
- Stealth Clothes: Whenever Dororo sneaks into a guarded place to steal, he wears the tengui disguise.
- Tagalong Kid: Dororo simply tags along without Hyakkimaru's say-so.
- To Be a Master: To be the world's greatest thief.
- The Reveal: Dororo is a girl. However this is not the case in the 2019 adaptation, as the creators have gone to say they're not trying to hide Dororo's sex and gender that go around. She's even worried about what the nun that took care of her when she was sick and washed her clothes might have said.
- Treasure Map: The tattoo on Dororo's back reveals that it is a map to treasure, drawn on her back by her parents.
- Unsettling Gender Reveal: While Hyakkimaru and Dororo are taking a bath, the former tries to get the latter to bathe with him, and in the process discovers Dororo is girl. Averted in the 2019 adaptation, where Hyakkimaru is simply informed by a nun taking care of her when she is sick.

Portrayed by: Satoshi Tsumabuki (movie), Hiroki Suzuki (2019 Stage Play)
Son of Daigō Kagemitsu, young Hyakkimaru had his body parts stolen by the demons that his father made a pact with. As a result, the vast majority of his body is prosthetic, and he can't see, hear, smell, or even talk. He goes on a journey to kill the demons and take back his body bit by bit.
- Absolute Cleavage: Hyakkimaru wears a tattered, loose-fitting yukata that leaves the better part of his chest and stomach exposed. 2019 Hyakkimaru stars much more covered up, but loses the Badass Cape and scarf after several episodes, rendering him just as exposed as his earlier counterparts.
- Adaptational Attractiveness: None of Hyakki's adaptations feature him as ugly by any means, but the 2019 rendition of Hyakkimaru is much younger looking and far less muscular. The intention was to make him look "cuter" for that version.
- The "Hyakki Maruo" version is more of an ikemen, who is still rather muscular and fit despite being quadriplegic.
- Adorkable: The more gentle moments when he doesn't know how to deal with things people take for granted. In episode 2, Dororo has to stop him from eating fish raw right off his sword arm. He steps in the fireplace with his own leg, burns it and tries again after wondering how that happened for a moment. Later, Dororo covers his newly regained ears with a piece of cloth and ties it with a bow on the top. When Mio asks him to speak, he closes his mouth and sticks fingers in his ears in refusal.
- Affectionate Nickname: Called "Aniki"/"Bro" by Dororo during their travels.
- Age Lift: Inverted. Interestingly enough, despite his younger and less muscular looks, he's older in the 2019 anime - sixteen years old, while his manga counterpart was fourteen.
- Artificial Limbs: And ears, and eyes, and nose...
- Attack! Attack! Attack!: At least in the 2019 adaptation, this seems to be his go-to strategy for dealing with demons. He won't stop until his target is killed, disregarding anything that might happen to him or to those around him as long as no one is in immediate danger. Jukai wonders if this isn't because he can't feel pain, and therefore has no normal self-preservation. Eventually, this crosses over into Fearless Fool territory as he gets more of his parts back, as his injuries end up becoming more debilitating for him. This comes back to bite him in the butt hard when he rushes to fight the Arijigoku (antlion demon) while injured twice. The first time he gets his real foot bitten off. The second time, he ends up leaving Mio and the kids undefended.
- Badass and Child Duo: The Badass to Dororo's Child.
- Berserker Tears: Hyakkimaru does not take the death of Mio well in any of the adaptations. In the 2019 anime he also briefly sheds tears as he delivers the killing blow to the Arijigoku.
- Bishounen: Hyakkimaru in the 2019 anime is basically a living, life-sized ball-jointed doll, and he has a face to match.
- Blade Below the Shoulder: Hyakkimaru's prosthetic arms conceal a pair of katana.
- Blind Seer: While he has no eyes, he does have the ability to see the souls, which helps him get by despite the absence of every other sense.
- Blind Weaponmaster: With the weapons as part of his body, no less.
- Cloud Cuckoo Landers Minder: In the original, Hyakkimaru constantly had to be on the lookout for Dororo's reckless behavior, saving the kid wherever he got in trouble and having to physically pull the kid away from a fight if need be. Less so in the 2019 version, where Hyakkimaru can't take care of anybody in his condition.
- The Corruption: The boy's soul is mostly white, but streaks of red are always present and threaten to get larger if he doesn't get placed in check.
- Cyborg: Lampshaded in the manga, where Jukai tells him that he'd be considered one "in sci-fi jargon."
- Depending on the Writer: His physical age depends on who writes the adaptation at the time. In most, he's a teenager, but in a few adaptations, he's a young adult during his journey. His hair color also changes from adaptation to adaptation, going from gray to blue to black, while his personality goes from cocksure to a tortured individual.
- Detect Evil: Like with Biwa-Houshi, he can sense the energy of others and can tell what is edible, good/neutral, and evil.
- Disabled in the Adaptation: While manga Hyakkimaru and 2019 anime Hyakkimaru are missing all the same parts, 2019 Hyakkimaru lacks most of the telepathic abilities the former had to bypass his lack of ears and vocal cords. Thus he starts the series off as entirely deaf and mute, whereas his manga counterpart could at least communicate verbally.
- His counterpart in Young Black Jack, Maruo Hyakki, is a quadriplegic and obviously can't gain the limbs back or regenerate them. He makes do with prosthetics for his hands and a wheelchair.
- Disability Superpower: His lack of a central nervous system while piloting his prosthetic body in the 2019 adaptation actually gives him an edge in battle, as he feels no pain, making him an unhesitating killing machine. It's an interesting take on the anime, since his quest to become more human gives him back these senses, among other problems.
- Driven to Suicide: At least two times in the manga he seriously considers killing himself. Luckily, Biwa-Houshi brings him back from the brink each time.
- Eerie Pale-Skinned Brunette: In the 2019 adaptation.
- Feel No Pain: As a side effect of having a prosthetic body, Hyakkimaru can survive sword cuts and stabs without so much as flinching. In the remake at least, his sense of pain was one of the things taken from him. He gets it back after killing Bandai in episode 2. He at least discusses this trope in the manga, saying that because he has no pain threshold he also has no idea how much his body can take before giving out.
- Jukai notes that since Hyakkimaru doesn't feel pain, he fights without fear and picks fights without any consideration. He keeps that trait even when regaining his ability to feel pain.
- Handicapped Badass: Hyakkimaru, for a certain definition of 'handicapped' - though his goal is to become less handicapped as time goes on.
- One could say he would do better with his handicap, as any major injury can be brushed off since most of his limbs are prosthetics (he once sustained an arrow injury to the back and lived because he hadn't regained it yet) and more than once he's used them to stash hidden weaponry (he did a Your Head A-Splode on a nine-tailed fox by throwing his prosthetic nose, which was a bomb, into its mouth). In Blood Will Tell, he gains stats when he recovers his bodyparts, and while he does lose access to various advantages his prostheses provide as he gains his actual bodyparts (specifically, his Arm Cannon and Leg Cannon and his moveset involving his double katana arms), he gains new abilities in return, such as dashing.
- He Who Fights Monsters: According to Biwa-Houshi. He warns Dororo that Hyakkimaru might become the same as the demons he fights.
- Hiding the Handicap: Notable for him hiding some massive disabilities with masterful use of Telepathy. His speech, hearing, and sight are masked by mouthing while telepathically communicating, while he hides his amputee status with realistic enough prosthetics. Averted in the 2019 version, where he's so isolated from the rest of the world that he can't even begin to hide it.
- Magic Is a Monster Magnet: Has a tendency to draw ghouls and demons to him, hence why Jukai saw it necessary to teach him how to fight.
- Meaningful Name: Hyakkimaru's name 百鬼丸 contains the kanji for "hundred demons."
- Moses in the Bullrushes: Was sent drifting down the river either by a father who didn't care what became of him (in the manga) or a midwife who was ordered to drown him but instead took pity on him.
- No Sense of Personal Space: Growing up deaf, blind, and mute, 2019 Hyakkimaru doesn't have a lot of options for communication. So when he does reach out to others, it's usually by touch—whether his theoretical conversation partner is comfortable with it or not.
- No Social Skills: In the 2019 anime. Growing up deaf, mute, blind, and largely isolated from people didn't exactly do much for his communication skills, verbal and nonverbal.
- Parental Abandonment: Was subjected to this at the very beginning, when his birth father Daigo sacrificed him to demons and then sent him along the river. In the manga at least, he's still rather hurt by his treatment.
- Peek-a-Bangs: Generally his bangs will cover his right eye, which is often handy as that's also the eye that he won't get until later.
- Psychic Powers: Hyakkimaru uses these to compensate for his missing bits, using ESP to see and hear, talking telepathically and presumably using telekinesis to do things like moving his food where it's supposed to go until he gets his esophagus back. In the original manga, it's said to be something anybody can do with practice (though he clearly has an unusual aptitude for it), but Blood Will Tell wisely changes them to mystical powers he was given by the gods to fight the Majin with. Getting each part back increases your stats because it frees up more of his power to use for fighting instead of keeping himself alive.
- Psychic Link: He also has one of these with Dororo. This is a major plot point in the game.
- Samurai Ponytail: A messy one that hints at his heritage.
- Screaming Warrior: Downplayed in the 2019 anime but he's gained this status once he got his voice back, baying with grief during his Extreme Mêlée Revenge against Mio's killers and doing so to call for Dororo during the Nokosaregumo fight. It might be in part because he hasn't quite gotten the hang of articulating words yet.
- Sleeps with Both Eyes Open: Having lived most of his life without eyelids, 2019 Hyakkimaru hasn't gotten into the habit of closing them while he sleeps. Luckily, he doesn't have real eyes to bear the damage.
- The Speechless: In the 2019 anime. Even after regaining his voice at the end of episode 5, he's reluctant to use it, as he finds the sound of his own voice unpleasant—and only knows about four words. He starts to speak more by Episode 13 of the 2019 Anime.
- Suddenly Voiced: His first words aren't all that great, considering his was reeling from his first love's death:"Mi...o..."
- Tears of Joy: Once he finally regains his sight, the first thing he does is weep for joy as he takes a look at Dororo for the first time.
- Terse Talker: 2019 Hyakkimaru gradually becomes one. Even after he starts getting the hang of speaking, he often drops nouns, only uses simple present tense, and tends to resort to sentence fragments when speaking about direct or indirect objects he can't omit entirely.
- Tragic Keepsake: He keeps the rice seeds Mio bought in his pouch.
- Unstoppable Rage: In episode 6, after coming back to see Mio and the kids she was taking care of being murdered, he loses it and slaughters the samurai responsible.
- Unusual Weapon Mounting: Hyakkimaru's legs have water guns in their knees, which he uses to douse demons with holy water (he gets his left leg back from the first demon he tries it on). His nose is also an explosive, though luckily he grows a real nose after he uses it to blow a demon fox's head off.
- Wild Child: In the 2019 anime, as his lack of senses made it difficult to communicate with what little human contact he had growing up. Not only does he have No Social Skills, he doesn't even have language.
- Wonder Child: Especially in the 2019 anime, where Jukai discovers him while on the verge of a Despair Event Horizon in a manner implying that the Buddha brought them together.
- Wouldn't Hit a Girl: Hyakkimaru's a gentleman despite his lack of complete awareness, so his earlier versions were more reserved about killing women. He tells Dororo this when the kid asks for Hyakki to kill them, so he can make Dororo aware of themselves. In the 2019 version he has less reservations, given the second monster we saw disguised itself as a woman, but that can be justified as he can't see or distinguish between male and female soul energy.

Hyakkimaru's father. A ruthless man who makes a deal with demons to secure power for himself. In return, he sacrifices Hyakkimaru's body parts to the demons, then demands that baby Hyakkimaru be killed.
- 100% Adoration Rating: In the 2019 version, he's loved by his people for making their lands so rich and prosperous.
- Abusive Dad: Even after sacrificing Hyakkimaru, he still treats him with contempt.
- Archnemesis Dad: He offered up "anything" for power, in spite of being told that making a pact with demons was a bad idea. And once he learns that Hyakkimaru is alive, he's dedicated to killing him.
- Ambition Is Evil: On the one hand, he was looking out for his lands and people...but on the other hand, he wanted to boost his reputation along the way.
- Deal with the Devil: Makes a pact with 48 demons (12 in the 2019 anime) where they took his firstborn son's body parts, giving him power in exchange.
- Hate Sink: The story more or less does a good job at showing what an irredeemable scumbag Daigo is. He is responsible for why his son Hyakkimaru is missing so many limbs, and he oppresses his own people with an iron fist.
- Averted in several adaptations, such as the PS2 game and the 2019 adaptation where he's made more sympathetic.
- I Have No Son!: Only considers Tahōmaru as his son and heir, and Hyakkimaru as a menace.
- Lack of Empathy: It takes an extremely cold-blooded person to sacrifice their own children out of selfish greed.
- Ludicrous Gibs: Spontaneously explodes after being possessed by a demon in the movie.
- Powered by a Forsaken Child: His rise to the top is the result of sacrificing his first baby son to demons.
- The Sociopath: He is more than happy to sacrifice his own son for power, treats his own people like crap and overall shows zero remorse for his actions.
- X Marks the Hero: Subverted. The cross mark on his forehead was given to him by the demons.

Wife of Kagemitsu and mother of Hyakkimaru and Tahōmaru. After her first son was sacrficed to the demons, she prays everyday to a headless Buddha statue, begging for forgiveness.
- Adaptation Name Change: Her name in the 2007 movie is 'Yuri'
- Adult Fear: She lived it when her firstborn son was born skinless, eyeless and limbless and told that he doesn't have much time to live.
- Broken Bird: Seeing her first son become skinless, eyeless and limbless right after his birth and then her husband taking him away to die away from her, essentially broke her. Despite her land being prosperous and having a second son, she spends her days praying in depression.
- Death by Adaptation: She's alive at the end of the Manga but in the 2007 movie she dies
- Driven to Suicide: In episode 12 after meeting a grown up Hyakkimaru, she begs for his forgiveness for the horrible things they did to him and the fact that they still need the demons to survive. But she attempts suicide so he isn't the only one to suffer.
- Lady Macbeth: She's an inversion. She's not ambitious at all and in fact is regretful over what they did to Hyakkimaru, openly admitting that they deserve punishment for their actions and calling out her husband for doing all this for his ambition.
- Parental Neglect: Due to her regret over what happened to Hyakkimaru, it seems she never really spent a lot of time looking after Tahōmaru.

Second son of Daigō Kagemitsu, and younger brother to Hyakkimaru. Heir to his father's lands, and shares the same militaristic outlook.
- Ascended Extra: He ends up being one of the last people Hyakkimaru fights in the series, but in the original, he's largely a one-off. Later adaptations would give him a more important role, and the 2019 continuity pretty much uplifts him to main character status.
- Anti-Villain: He stands against Hyakkimaru because he feels only the demons can protect his people.
- Blood Knight: He's way too eager to go to war.
- Broken Pedestal: He learns everything that Daigo did to Hyakkimaru in episode 12 and is very disgusted by both his parents for their actions. He still stands with his father regardless.
- Eye Scream: He loses one of his eyes in episode 12 while fighting Hyakkimaru.
- HeelFace Turn: In Blood Will Tell he stops fighting Hyakkimaru after finding out Hyakkimaru is his older brother and later abandons his father's militaristic outlook. He even turns against his father to join his brother and Dororo in defeating the Fiends. Sadly, he sacrifices himself to save Dororo from being possessed by Fiends — Hyakkimaru has to cut down the possessed Tahōmaru.
- Hero-Worshipper: Episode 10 of the 2019 version shows that he looks up to his father, Daigō thinking he's the cause for their land's current prosperity. He is, but not for the reason Tahōmaru thinks.
- Meaningful Name: His name 多宝丸 contains the kanji for "many treasures," which lets the audience know exactly how his father views him in comparison to Hyakkimaru.
- The Needs of the Many: Tahomaru decides to fight against Hyakkimaru despite knowing and being disgusted by what his father did to Hyakkimaru because he can't risk his country suffering.
- Reasonable Authority Figure: Episode 10 of the 2019 version has him helping a small village in his land and working to kill the monster that was infesting their water simply because he felt it was his responsibility to protect his people.
- Red Herring: The game teases that Hyakkimaru's missing parts have all conglomerated into one other being. Tahōmaru is introduced having the opposite eye that Hyakkimaru lacks, hinting it might be him, but he's not; Dororo is.
- Spared by the Adaptation: He dies after his fight with Hyakkimaru, but in the movie his life is spared.
- The Unfavorite: He feels this way for both his parents as he states in episode 6. He can tell his mother loves someone else more than him, while he can tell his father values his ambition more than he values him as a person.
- "Well Done, Son!" Guy: Even before he found out he had an older brother, Tahōmaru was constantly trying to please his mother (who was still in mourning after Hyakkimaru was taken away).

A Wandering Monk with a biwa, he accompanies the duo in their adventures.
- Detect Evil: Being blind doesn't stop him from detecting the energy of beings, especially demons. Hyakkimaru also shares this ability with Biwa-Hoshi.
- Exactly What It Says on the Tin: "Biwa-Hoshi" literally means "lute priest," and he goes unnamed in the Tezuka manga. Time will tell if this is true in the 2019 anime.
- Handicapped Badass: Is blind. Still capable of killing demons with one slice.
- Hidden Weapons: His biwa holds a blade.
- Nice Guy: He cares about the well being of Dororo and Hyakkimaru.
- Single-Stroke Battle: In the manga, he demonstrates to Hyakkimaru how to fight by slicing a fly in half. In the first episode of the 2019 anime, a demon challenges Biwa-Hoshi and is dealt with similarly.

Hyakkimaru's adoptive father. A doctor who specializes in prostheses, he gave Hyakkimaru a body, including Hyakkimaru's katana-concealing arms.
- Adaptational Villainy: In the manga, all that is said of Jukai is that he's a doctor. In contrast, the 2019 anime gives Jukai a backstory where he used to work for a brutal warlord and was responsible for the crucifixion of would-be rebels.
- The Atoner: How he feels after being rescued by a foreign ship, opening a free clinic in a village afterward in the 2019 anime.
- Due to the Dead: He spends most of his time now wondering battlefields and fitting the corpses with his prostheses so they're presentable.
- Heroic BSoD: His apprentice Kaname leaving in disgust when he discovered Jukai's history essentially broke him and he spent the day wandering in a daze. He only broke out of it when he found Hykkimaru.
- My God, What Have I Done?: After seeing a woman get mercilessly cut down by his lord for simply begging to not have her husband crucified, Jukai has this reaction and tries to commit suicide by throwing himself off a cliff in the flashback of episode 3 for the 2019 anime.
- Reformed, but Rejected: All of his apprentice's goodwill towards him dries up when he learns of Jukai's past. Even after being talked down from killing Jukai on the spot, the boy refuses to forgive him and casts aside his prosthetic leg before walking away for good.

A young girl that the duo and Biwa-Hoshi meet while traveling. She lives in an abandoned house and takes care of a group of children who were affected by the war. She is the love interest of Hyakkimaru.
- Cool Big Sis: The children that she cares for view her as a very loving big sister.
- Cope by Creating: She sings so that she doesn't feel sadness even when she's selling her body.
- Death by Adaptation: Her death in Blood Will Tell is slightly different than in most versions, as there she's killed by one of the Fiends instead of by Daigo's soldiers.
- Defiled Forever: Mio reveals that she feels dirty for selling her body every night, even thinking her soul is dirty.
- Subverted in the 2019 anime. Shortly after Mio voices her concerns, the scene cuts to Biwa-hoshi's perspective showing her soul to be spotless. Later, Dororo reacts very poorly when Mio calls his mother "admirable" for never taking up sex work—a decision which led to her starving to death—and counters that Mio is just as (if not more) admirable for doing what most wouldn't to survive.
- Love at First Note: Her songs are very beautiful and Hyakkimaru first meets her by following the sound of her singing. Mio's songs are the only sounds that can calm Hyakkimaru after getting his ears back.
- Hooker with a Heart of Gold: To get money to sustain herself and the children she takes care of, she sells herself to soldiers at night as a job.
- Not What It Looks Like: She sells herself to multiple enemy camps, which leads to one of them thinking she's a spy.
- Nice Girl: She's a very sweet and kind person. When Hyakkimaru is attracted to her singing and follows the sound to her, she realizes that he's blind, but doesn't act in fear and is very friendly towards him in their first meeting. She also decides to let him, Dororo, and Biwa-Hoshi stay in her home.
- Stuffed into the Fridge: She's murdered by soldiers who mistake her for a spy, which triggers Hyakkimaru into an Unstopabble Rage.
- Too Good for This Sinful Earth: Too good indeed... She's one of the most kind-hearted and selfless characters in the story. And her kindness is repaid with her being killed.
- Tragic Dream: She wanted to grow a large rice paddy so that she and the children would no longer starve. And she had just purchased seeds the day they were all killed.
Hibukuro and Ojiya
Voiced by: Kenta Miyake (Hibukuro, 2019 anime), Ayumi Fujimura (Ojiya, 2019 anime)
- Blade on a Stick: Hibukuro's personal weapon in the 2019 adaptation, so much so that a samurai actually recognized him because of the weapon.
- It's Personal: Ojiya has no mercy for samurai, given that most of her family had been killed in war circumstances either directly or indirectly caused by them. Hibukuro also loathed samurai and created a bandit group made solely of disgruntled farmers just to raid them.
- Good Parents: They both loved Dororo and despite being down on their luck later on, they focused on keeping him alive.
- Outliving One's Offspring: Their two eldest children both died before the flashback.
- Silk Hiding Steel: While a dutiful wife and mother, Ojiya also had the means to protect her household as well and knew how to fight in the manga. Less so in the 2019 version.
- Taking You with Me: After Hibukuro is fatally stabbed, he grabs his murderer and gives him a bear hug so the blade pieces him too.
