Main Characters

Protagonists

Yamato Jinka

Voiced by: Soma Saito

The protagonist of Part 1.

---

• An Arm and a Leg: Loses an arm fighting Jinun, though he later forms a replacement out of energy.
• Asian Fox Spirit: His Spiritual Awakening technique transfers Tama's spiritual energy into his body, causing him to gain wild golden hair, fox ears, and grow tails made of Pure Energy (increasing up to nine as he learns better control of the technique). He later rockets up to 1000 tails after eating the flesh of a Mountain God, causing him to become mode-locked as an insane "divine beast". After his power in this form is stabilized he becomes an actual kitsune, capable of transforming between "giant fox" and "fox-eared humanoid" forms.
• Berserk Button: Humans disrespecting demons pisses Jinka off a lot, as do people threatening Tama.
• Black Eyes of Crazy: When he starts transforming into the Beast God he gets black sclera. His eyes turn back to normal when he regains his sanity.
• Blood Magic: He activates the Spiritual Awakening by drinking Tama's blood.
• Can't Hold His Liquor: Collapses immediately after one sip of the orangutan's sake.
• Character Development: His utter hatred for humans gradually gives way to understanding that humans and demons share the same soul in the end, and it's their experiences that craft who they are. Unfortunately, he's still determined to become a demon, and ends up going too far before he can stop himself.
• Declaration of Protection: Jinka doesn't really care about Tama's attempt to spread peace and love among humans, but sees himself as her protector and would crush anybody with great prejudice should they attempt to hurt her.
• Decoy Protagonist: After Jinka became a thousand-tailed divine beast, he gave the stage over to Senya after the run of the first arc. As the Void Tribe's tool, his days are spent at their beck and call devouring gods.
• Deity of Human Origin: At the end of Part 1, Jinka is transformed into a thousand-tailed fox god, making him simultaniously this and a Demon of Human Origin.
• Elemental Powers: Each of the tails that he obtains during Spiritual Awakening grants control over a different element.
  • His first tail grants the ability to summon the Earth God to form a massive fist of earth.
  • His second tail grants the ability to summon the Inferno Princess, a fire elemental.
  • His third tail grants him the ability to summon the Water Dragon, a water elemental that is used defensively.
  • His fourth tail grants the ability to summon the Elder Tree, which he uses to constrain and restrict opponents.
  • His fifth tail grants the ability to summon the Silver Blade, a massive sword.
  • His sixth tail is made out of lightning.
  • His seventh tail is a tornado called the God of Wind's Lance and enables him to move at superhuman speed.
  • His eighth tail is made of light.
  • His ninth tail is made of darkness, and Jinka also refers to it as The Power of the Void.
• Eyepatch After Time Skip: He sports an eyepatch over his left eye in the final chapter, which takes place after a 200-year timeskip.
• Fire-Forged Friends: With Senya and Mudo by the final chapter.
• Flaming Hair: In his Spiritual Awakening his hair appears to be made out of fire.
• Forceful Kiss: His first Spiritual Awakening with Tama involved him kissing her by surprise. When she calls him out on the implications of doing so while calling her his sister, he cheerfully says he's OK with that.
• Freudian Excuse: The reason he hates humans so much? His real family seemingly abandoned him (they had a good reason) and a couple of his demon friends were killed by humans.
• Full-Name Basis: Very few people in the story outside of his social circle ever call him anything but his full name.
• Humanoid Abomination: After becoming the 1000-Tailed Fox God, he's so powerful that even the Tribe of the Void are only able to point him in the direction of a god they want killed and watch the ensuing Curb-Stomp Battle. Even the Mountain Goddess was frightened by his vast amount of spiritual energy and that he was blighting the earth around him.
• I Just Want to Be Special: Wants to become a yokai due to his hatred of humans.
• Jagged Mouth: Initially used for comedic effect whenever he was angry. After his transformation into a mad god, not so much.
• Kill the God: How the Tribe of the Void seems to be using him, and Jinka doesn't just kill the gods... he eats them.
• Likes Older Women: He is quite a lot younger than Tama, and has vowed to marry her once he gets a demon body.
• Magical Eye: Something that bordered on Unusually Uninteresting Sight as none of the characters had cared to mention it until the Mountain Goddess brought it up. It's actually a Fairy Eye, and allows Jinka to see the aura of living things.
• Magnetic Medium: Jinka and his twin brother Takeru were born with the Fairy Eye, and as such, attract demons when they are together.
• Misanthrope Supreme: Jinka has expressed his hatred of humanity many times in the series, and would much rather be a demon than a human. Tama's goal is to get him to let go of this negative attitude, which he eventually does.
• Monstrous Cannibalism: After becoming the Thousand-Tailed Kitsune, he is a god that eats other gods.
• Not Blood Siblings: He calls Tama his sister, but they're not actually related to each other and he eventually proposes to her.
• Official Couple: He asks for Tama's hand in marriage once he becomes a demon, and she accepts once he becomes the Thousand-Tailed Demon Fox. By the final chapter, they're still happily married 200 years and counting.
• One-Winged Angel: After eating the mountain god Taizan's flesh he attains nine tails, and when Yazen tricks him into thinking he's killed Tama he transforms into a 1000-tailed kitsune.
• Parental Abandonment: He ended up being left with Kokugetsu Sai because of his fairy eye.
• Pent-Up Power Peril: After returning to sanity in Chapter 96, this happens and they have to shape the energy before it explodes within him.
• Physical God: After consuming Taizan's divine flesh, he becomes a thousand-tailed kitsune-god.
• Sanity Slippage: Yazen notices his mind was starting to deteriorate due to the massive influx of spiritual energy he received from eating Taizan's flesh, and pushed him over the brink by tricking him into thinking he killed Tama.
• Super Mode: His Spiritual Awakening temporarily turns him into a kitsune. He wants to find a way to make the change permanent, and succeeds in the penultimate chapter.
• Took a Level in Badass: He goes from having four tails at the start of the series to become a thousand-tailed divine beast at the end of the first arc.
• With Great Power Comes Great Insanity: His sanity starts to deteriorate after he eats Taizan's flesh during his fight with Yazen, who takes advantage of that by tricking him into thinking he killed Tama. It backfires when he transforms into the Beast God after succumbing to madness.
• Yin-Yang Bomb: His "Souls of the Five Elements" combines the Elemental Powers of his first five tails (earth, fire, wood, water and metal) into a massive energy ball capable of burning off one of Jinun's arms and seriously injuring Douren. He is also capable of combining his sixth and seventh tails (wind and lightning) for the "Storm Road" technique.

Senya

Voiced by: Hiroki Nanami

The protagonist of Part 2.

---

• Affectionate Nickname: Yoshiteru calls him "Whitey", for his white hair.
• Amnesiac Villain Joins the Heroes: In Part 2 he had completely forgotten whatever happened before the Mountain Goddess sealed him and Jinun, and ends up becoming an Amnesiac Hero as a result. He eventually regains his memories, and decides to leave behind his past at the Dangaishu.
• Babies Ever After: He and Tsukiko have several children and grandchildren.
• Badass Pacifist: Is trying his darndest to be this in Part II. He slips up when a mad god attacked him, but he later finds a way to make it work.
• Battle in the Center of the Mind: He can enter into the mental worlds of those being controlled by the Tribe of the Void.
• Black Eyes of Evil: Senya possesses Empty Eyes resembling black scribbles, and Shinsuke states that when he first met Senya and looked into his eyes he saw a river of blood.
• Break His Heart to Save Him:
  • Senya makes the difficult decision to leave Tsukiko behind to go after his father and the Tribe of the Void, fearing that one day he would become something neither demon nor human, like Jinka. She follows him anyway.
  • He tries to do it again after the final battle with the Tribe of the Void, but she's having none of that.
• Character Development: In Part 1, he starts off nearly emotionless and follows his father's orders to the letter, though a measly toy manages to distract him and Shinsuke sparing his life spurs a semblance of emotion. The amnesia he suffers after his sealing and actually being able to grow and experience the ups and downs of life takes time but drastically shifts him into probably one of the most empathic and kind individuals of the entire cast.
• The Chosen One: According to Hekke Neko, he's he only one able to stop Jinka from destroying Japan in his quest for strength.
• Contrasting Sequel Main Character: He is essentially a demon who wants to be human, in contrast to Jinka being a human who wanted to be a demon.
• Deity of Human Origin: In the final chapter, it's revealed that Senya — ironically for someone who desired to become human — has transcended into a divine being called the White God.
• Early-Bird Cameo: The final chapter strongly implies that he is the White God mentioned in Spirit Circle.
• Eleventh Hour Super Power: The battle against the Thousand-Tailed Fox pushes him to awaken in order to rival Jinka.
• Empathic Weapon: Acquires a katana containing the soul of Yoshiteru.
• Enemy Within: The manifestation of his guilt over killing Tsukiko's father and fear that he would lose control of his demon powers, which manifested as a monstrous version of himself, terrified of the happiness that will purge it and influencing his decision to run away. Senya is briefly corrupted by it before Tsukiko restores his sanity with a Love Confession.
• Energy Bow: He forms one in the final battle against Jinka.
• Enlightenment Superpowers: During the final battle against the Tribe of the Void, he embraces the belief that he can become anything and attains enlightenment, becoming immensely more powerful and capable of purging the Tribe of the Void's influence by simply touching their victims. It's implied his body can't handle the strain of forcing godhood upon himself for very long.
• Expy: Senya not only looks like a younger version of Maimakterion from the author's previous work, but also has a similar set of shapeshifting powers.
• Good Eyes, Evil Eyes: Depends on the situation, his eyes can appear full of bloodlust and malice.
• Good Smoking, Evil Smoking: Takes Furuon's pipe as a memento, though he loses it to his father after their first duel.
• Happily Married: He and Tsukiko were together nigh on forty years before she died of old age.
• Heel–Face Turn: After getting Laser-Guided Amnesia he becomes the protagonist of the second arc.
• Humanoid Abomination: He has the potential to become a transcendental entity called the Thousand Demon Devil, which he does later in his final battle against Jinka. However, by this point he has reached peace of mind enough to not be driven mad by the power.
• Idiot Hero: In the final chapter, Mudo remarks Senya's become increasingly simpleminded over the centuries.
• I Just Want to Be Normal: Heading down this route, as he has stated that he wants to become a human in recent chapters.
• It's All My Fault: The real reason Senya wanted to run away from Tsukiko and the others was because deep down he blamed himself for killing her father and was afraid he'd lose control and kill her, seeing himself as unworthy of happiness.
• It Was a Gift: One of the boys Senya makes friends with gives him a cat-shaped rock to keep by him before he leaves the village. He tries to use it as a bargaining chip since he sees it as a "valuable object", and he gets pretty upset when it breaks later on in the story.
• Just Friends: He insists his relationship with Setsu the yuki-onna is purely platonic, despite ribbing from Jinka and Mudo.
• Kamehame Hadoken: His Roaring Thunder Blast technique fires a focused beam of ki.
• Living MacGuffin: The Tribe of the Void are after the Jewel of 1000 Wonders sealed inside his body.
• Long-Lived: Hekke Neko is quick to mention that he would be in for a very long lifespan by the time he awakens to the rest of his powers.
• Lovecraftian Superpower: Courtesy of having 1000 demons sealed inside him, he can freely shapeshift his body to form extra limbs, tentacles, spikes, and other grotesque weapons and appendages.
• Many Spirits Inside of One: The souls of the 1000 yokai inside him initially appears as a black mass with multiple sets of eyes and jagged mouths. He later learns the names of each and every one of them, letting them individually manifest within his mindscape. After he attains enlightenment they manifest as monks.
• Martial Pacifist: Post time-skip, he doesn't like fighting, but he will if he has to.
• Mirror Match: Senya is corrupted by his Enemy Within, and engages in a pummel duel with him.
• Multi-Armed and Dangerous: Senya's awakening grants him 1000 arms, born from his desire to save everyone.
• Night Parade of One Hundred Demons: His recurring character motif is this (a thousand in his case, giving him the name of his Signature Move Senki Yako). After going full pacifist, he replaces the motif, taking on the looks of the thousand-armed Buddha.
• Noble Male, Roguish Male: Has this dynamic with Mudo. Where Mudo is a very outspoken, macho, and physical guy who solves his problems with a good fight, Senya is a more gentlemanly person who doesn't resort to full-on fighting unless it's necessary.
• Official Couple: He finally confesses his feelings for Tsukiko in Chapter 92, and they are Happily Married for forty-some years.
• Pastimes Prove Personality: In the final chapter, Senya tells Mudo he's made a hobby of climbing snowy mountains. This is to test and renew his determination to live for the sake of all his long-lost friends and loved ones.
• Physical God: By the time of the final chapter, he has become revered as the "White God", a mysterious entity who shows up amidst calamitous circumstances, resolves them, and vanishes.
• Puppy Love: He certainly blushes a lot around Tsukiko. All but confirmed when he states he really likes her in Chapter 44, and they wind up getting married.
• The Reveal: Senya is a descendant of the Tribe of the Void, the group of cloaked figures behind Jinka's transformation into the Beast God and the ones driving the Land Gods insane.
• Sealed Badass in a Can: He was sealed after the fight with the Mountain Goddess when he tried to rescue Jinun. He has currently been unsealed and is now with Shinsuke and Tsukiko.
• Sealed Inside a Person-Shaped Can: Has a thousand demons fused into his body, and is hailed as a future demon god who has the potential to become even more powerful than Jinun.
• Shipper on Deck: Not Senya, but his demons are rabid Senya x Tsukiko fans.
• The Stoic: Shares this with Jinun, although he starts developing out of this after his Heel–Face Turn.
• Third Eye: In his ultimate form, he gains an eye in the middle of his forehead.
• Tyke Bomb: Fused with a thousand demons at the age of eight years and is one of the best fighters in the series. To put things into perspective, this eight year-old kid shreds apart two tengu demons whom Jinka has stated as possessing great spiritual power in a few seconds.
• Unable to Cry: After Yoshiteru is killed, Senya finds that he can't work himself up to cry about the death, a fact that he links to his memories and old personality returning. He gets the ability back when his demons and Yoshiteru's soul help him learn to be at peace with himself.
• Vitriolic Best Buds: He and Mudo may bicker and insult each other like there's no tomorrow, but by the end of the series they're close friends.
• Walking the Earth: After Tsukiko dies of old age he departs the hidden village and roams Japan for 200 years, accompanied by a yūrei named Enra Enra and a tanuki-god of misdirection. He also frequently visits Mudo and Jinka, and the three periodically team up and save Japan from mad gods and other calamitous threats.
• Weak, but Skilled: In comparison to Mudo.
• "Well Done, Son" Guy: It turns out that Senya is Jinun's son. To better understand this, Senya has been calling Jinun "Master" from the beginning of the series and only revealed the fact that he was Jinun's son when he was trying to save the other from the Mountain Goddess.
• White Hair, Black Heart: When he was a member of the Dangaishu. Subverted once he becomes the protagonist.
• Why Did It Have to Be Snakes?: The 1000 demons sealed inside him are terrified of dragons. They get over it during Senya's match with Mudo.
• Worthy Opponent: Comes to see Mudo as such during their fight.

Youko Tama

Voiced by: Yūki Takada

• Actual Pacifist: She has never resorted to violence in combat, instead opting to enable Jinka's Super Mode and let him do the fighting. In Part 2, she resorts to illusions to avoid engaging in direct combat.
• A-Cup Angst: Implied. She never states anything outright, but she's shown she wants to be more voluptuous. During the final battle, she creates illusions of herself, Mudo, and Setsu— and hers has a more pronounced chest.
• Admiring the Abomination:
  • When she first saw Jinka's Spiritual Awakening form, she blushed intensely and thought that he was pretty.
  • Tama thinks Jinka's Beast God form is magnificent, though she still wants to turn him back into a human.
• Anguished Declaration of Love: When Jinka becomes the Beast God and starts rampaging, Tama tries to soothe him by professing her love for him and agreeing to marry him. It works… until the Mountain Goddess teleports her away.
• Animal Jingoism: Has a natural fear of dogs as a fox youkai.
• Asian Fox Spirit: As her name "Youko" suggests, she is a fox youkai.
• Berserker Tears: When she sees the Tribe of the Void have mind-controlled Shakugan.
• Blood Magic: Jinka's Spiritual Awakening is activated by drinking her blood.
• The Chessmaster: Has shades of this, using - or at least trying to use - her oratory skills to nonviolently diffuse conflicts.
• Even the Girls Want Her: Tsukiko expresses a great degree of... "admiration" towards Tama when they first meet.
• Fanservice Pack: When she shows up in Chapter 39 she appears to have become older, or at least more "developed" following the feedback from Jinka's One-Winged Angel.
• Interrupted Cooldown Hug: She is able to bring Beast God Jinka back to his senses, but the Mountain Goddess teleports her away, which causes him to lapse back into his Roaring Rampage of Revenge.
• I Will Find You: Spends the second half of the series on a journey to find Jinka, after his newfound 100-tailed fox form goes haywire and flies off.
• Little Sister Heroine: Invoked by Jinka when she first met him. Jinka initially calls her his little sister, switching to big sister when he learns she's older than him, but flirts with and even kisses her to activate his Spiritual Awakening. When she points out the incestuous overtones of him doing so, he cheerfully tells her he's OK with "forbidden sibling love".
• Master of Illusion: Has been shown to be able to create small illusions, which she uses to defend herself. After the time skip, she has powered up significantly due to her being apprenticed to another demon.
• Mayfly–December Romance: She's a youko of a hundred years, while Jinka is a human in his teens. Doesn't stop them from having romantic feelings for each other, which is confirmed when Tama tells a berserk Jinka at the end of the first arc that she will always love him, even if he can't turn back into a human now.
• Naked First Impression: Tama first meets Tsukiko in a hot spring, and the latter couldn't stop thinking about how beautiful she is.
• Official Couple: Jinka proposes to her before the final battle, and when he transforms into the Beast God she accepts in an effort to calm him down. She even spends 8 years searching for him, and by the final chapter they've been happily married for 200 years.
• Older Than They Look: Is around a hundred years of age, but pre-timeskip has the body of a young teenager.
• Power Makes Your Hair Grow: Tama's hair grows longer when Jinka absorbs so much energy that it feeds back into her and keeps him in demon mode.
• Red Baron: She was known as the Accursed Demon Fox pre-timeskip, and becomes known as the Golden Youko post timeskip.
• Religious and Mythological Theme Naming: Chapter 37.5 reveals that she is based on Tamamo no Mae, the golden kitsune featured in the Otogizōshi.
• Rescue Romance: She started falling for Jinka after he saved her from a trio of ronin, though she was tsundere towards him at first due to their differing opinions towards humans.
• Training from Hell: Tama spends ten years alone in her mind meditating - while only a day passes in real time due to the Mountain Goddess manipulating space-time. This causes an increase in her spiritual power, and actually shocks Jinun and Senya into silence when this is revealed during the battle.
• Tsundere: When she first met Jinka she was offended by his callous hatred towards humans, but begrudgingly started warming up to him after she learned he was the son of her old friend and being wowed by his Spiritual Awakening form.
• Unusual Ears: Possesses both fox ears and human ears.
• We Help the Helpless: As she says, she and Jinka are the saviour siblings of the world.

Takekichi/Hyoudou Shinsuke/Kazamatsuri Shinsuke

Voiced by: Ryōhei Kimura

• The Alcoholic: Is almost constantly drunk after the first time skip. He cleans himself up during the second time-skip.
• Ax-Crazy: Aimed only towards Resshin, though. He gets better.
• Character Development: And how. He's changed from a cowardly, near-useless swordsman to a rage-filled Determinator with only revenge on his mind. Luckily he gets over it and becomes a skilled, calm warrior.
• Determinator: Nothing could dissuade him from following Jinka and Tama on their journey. When he was younger, the insults of his swords master did nothing to stop him from attempting to learn the sword too.
• Enlightenment Superpower: He was the one who taught Senya how to enter an opponent's mental world.
• Evil Weapon: He was given the cursed sword Arabuki, which lets its master fly and launch powerful gusts of wind, by Zanzou. Following Shakugan's defeat, he constructs a stereotypical "wants to take over its wielder" persona for it. The evil part is ultimately subverted as Akaburi snaps him out of his Roaring Rampage of Revenge.
• He Who Fights Monsters: He nearly succumbs to this following Shakuyaku being Taken for Granite. Don't worry, he gets better.
• Hidden Depths: Was the first to complete the Mountain Goddess' training.
• Known Only by Their Nickname: Shinsuke is his warrior name. His real name is Takekichi. Only Barry, Tama, and Yamato know this.
• Meaningful Rename: He already dropped his old name before the series, to represent his growth from farmer boy to samurai. Yoshiteru gives him the Kazamatsuri ("wind festival") name after Shinsuke took him for a flight with Arabuki's power, and he kept it for the rest of his life, including passing it onto his descendants.
• Nice Guy: By the Time Skip he's treating demons and humans as equals, even reforming evil demons that Senya brings into good villagers.
• Put on a Bus: For a time, he and Raizou had been sealed inside a protected village as a result of a deal with Hanatora. They were still trying to find a way out eight years later, which they do in time to stop Shakugan from smashing Tama.
• Tagalong Kid: Decided to follow Jinka and Tama after seeing them with the bandits.
• Took a Level in Badass: After Shakugan's sacrifice he became serious.
• Training from Hell: Courtesy of the Mountain Goddess over the time skip, though it apparently amounted to a series of Curb Stomp Battles not in Shinsuke's favor.

Shakugan (Shakuyaku/Kagan)

Voiced by: Tomoyo Kurosawa

• Action Girl: She's the best fighter after Jinka in the group.
• All of the Other Reindeer: Shakuyaku was abused as a child because of her red hair.
• Babies Ever After: The final chapter shows Senya remembering Shakugan holding a young child with a mix between Shinsuke's hair and hers.
• Brainwashed and Crazy: They are being controlled by the Tribe of the Void for the final battle, up until Shinsuke breaks her conditioning.
• Go Out with a Smile: After being stabbed by Resshin she transforms into a stone, but her last expression is a smile.
• Hard-Drinking Party Girl: Held out longer than Douren during their drinking battle.
• Heroic Sacrifice: They sacrificed themselves to protect a defenseless Tama and a woman giving birth.
• The Ingenue: Was quite embarrassed when she had to go sleeveless in order to allow her new body-changing powers to have more effect.
• The Lost Lenore: Turning into a boulder during her Heroic Sacrifice left her as a major source of Shinsuke's angst and frustration throughout the story, as well as sort of a moral guiding light when things go south. She gets better.
• Naked on Revival:
  • When she is restored to her human form by Jinka at the beginning of the manga, she is naked.
  • When the Tribe of the Void freed her she was stark naked.
• Official Couple: She is obviously in love with Shinsuke, and he with her. They end up Happily Married, though oddly enough not much attention is brought to it: she simply becomes part of his family and even gives him a kid or two during the decades shown passing in the second to last chapter.
• Portmanteau: "Shakugan" is "Shakuyaku" and "Kagan" mixed together: even the particles in the kanji for "Shaku" are made by smushing characters from their original names together.
• Sharing a Body: Shakuyaku and Kagan are quite happy with this arrangement, as it were.
• He's Back!: She is reawakened and mind-controlled by the Tribe of the Void in Chapter 69, and broken free from the mind control by Shunsuke in Chapter 76.
• Stripperiffic: Her "wardrobe" during the battle against the Tribe of the Void consists of a rock bra and skirt, and nothing else.
• Taken for Granite: Exhausts her spiritual power to prevent a boulder Resshin dislodged from crushing a cabin containing Tama and a pregnant woman and turns to stone as a result. She gets revived later.

Humans

Kokugetsu Sai

• Body Surf: When Taizan gets tied to the hidden village, he possesses Hanatora.
• Dirty Old Man: His ghost possesses Taizan's body and tries to sexually assault Tsukiko, and openly ogles her and Tama during the Beach Episode. He later changes to Hanatora's body via an unseen but implied to be nauseatingly perverted fashion.
• Face–Heel Turn: With shades of Evil All Along, as he proclaims himself the master of "the wrong way, the Way of the Wicked" when offering to train Tsukiko. He still fights on the side of the heroes.
• Head-Tiltingly Kinky: His method of changing bodies wasn't shown or described, but left Tsukiko and Raidou nauseated and horrified Shinsuke when he figured out how it was done.
• Hijacking Cthulhu: It's noted that a human ghost being strong enough to possess a god, even a minor one, is highly unusual.
• Old Friend: It turns out he and Yazen used to be buddies, and he used to be friends with Tama and the Mountain Goddess as well.
• Our Ghosts Are Different: As a ghost he's strong enough to possess minor gods.
• Promotion to Parent: Looked after Jinka when his parents abandoned him.
• Red Baron: The Phoenix Killer, which he presumably earned by killing a phoenix.
• Right Under Their Noses: As an evil spirit, he thinks he's doing this by possessing Taizan, and forces Tsukiko and Nao to keep his presence a secret. Senya figures him out anyways, as he remarks that he's been training Tsukiko in sword fighting.
• Verbal Tic: Occasionally ends his sentences with "fueh".

Raidou Zanzou

Voiced by: Hiroki Tochi

• Aloof Older Brother: To Higan.
• Evil Weapon: Wielded the cursed katana Arabuki before giving it to Shinsuke.
• I'm a Humanitarian: There's a reason he's called Demon Eater Raizou; he eats and sells the meat of demons he kills.
• Offscreen Romance: Marries an ex-palace attendant during the 8-year timeskip and starts a family with her.
• Red Baron: The Demon Eater.
• Shipper on Deck: He supports Senya and Tsukiko.

Tsukiko

Voiced by: Maaya Uchida

• Anguished Declaration of Love: She tells Senya she doesn't blame him for her father's death, but that if he can't forgive himself then to make it up to her by making her happy for the rest of her life.
• Awesome by Analysis: Can predict an opponent's attacks by analyzing their eye movements.
• Badass Adorable: She's a blushing, soft-spoken little girl who can beat the crap out of a lower-class demon with a wooden sword, and who actually dares to stand up for Senya against a dragon.
• Badass Normal: Has defeated Tago twice and stood up to Mudo. She also attacks Jinun without hesitating in order to protect Senya and the Mountain Goddess.
• Can't Catch Up: She was always weaker than Senya, a fact that bothers her when she comes of age since she wants to be able to protect people instead of be protected all of the time. Specifically, she's mad that she can't match the strength of Senya and Mudo for all of her intense spiritual and physical training. Even on her deathbed, she apologizes to Senya for holding him back.
• Damsel in Distress: Is captured by Mudo twice in order to provoke Senya. They even pre-emptively lampshade it, as the clothes she received from Yoshiteru were noted to look like a "foreign princess", and those are what she wears for the majority of the arc.
• Deal with the Devil: Was willing to learn Kokugetsu Sai's Way of the Wicked if it could protect Senya.
• Deceased Parents Are the Best: Her father was killed during a rampage by a mad god.
• Declaration of Protection: States that she will fight for Senya if he doesn't want to fight any more.
• Determinator: Tags along with Shinsuke and Senya regardless of Shinsuke trying to dissuade her from following them.
• Died in Your Arms Tonight: In the penultimate chapter, she dies of old age after thanking Senya for a happy life together.
• Dual Wielding: Post-timeskip she keeps a pair of wakizashi, at least one of which was forged from the pieces of Arabuki, hidden in her cloak.
• Happily Married: She and Senya were married forty-odd years.
• Hidden Depths: Is very, very good with a sword. Yoshiteru, the man whom Raidou Zanzou said was a natural genius, stated that she had talent with a blade.
• I Just Want to Be Badass: She is depressed about not being powerful enough to protect Senya. She Took a Level in Badass as a result.
• Master Swordsman: Is good enough with a blade to cut down an earth god, despite only being a human.
• Official Couple: It's obvious to everyone that she's in love with Senya. She asks him to marry her in 92.
• Paper Talisman: Uses ones imbued with lightning magic as an adult.
• Precision F-Strike: Before the final battle, she gives Senya no small amount of hell for repeatedly trying to leave her behind when she explicitly trained to stand by his side. What results is basically berating Senya into acknowledging her strength at last, complete with a "Damn right!", leaving everyone else confused as to whether that was really Tsukiko speaking.
• Protectorate: For Senya. He always tried to make sure she wasn't fighting in the more supernatural battles and often came to her rescue. Part of it is guilt for failing to save her dad, part of it's a kiddie crush. However, she expresses a huge dislike of this in her teenage years since she wants to be able to protect others.
• Puppy Love: With Senya. Which is all but confirmed when Senya states in Chapter 44 that he really likes her.
• She Is All Grown Up: After the 8-year Time Skip she has matured into a competent and attractive young woman.
• Shock and Awe: One of her wakizashi, Itakebi, is imbued with lightning magic. She also employs lightning-based paper talismans against Jinun.
• Tagalong Kid: Reminds Shinsuke of his pre-Took a Level in Badass self.
• Took a Level in Badass: Following the second timeskip she is capable of taking on Taizan and Jinun.
• What the Hell, Hero?: She calls a "Family Meeting" specifically to berate Senya and Nau for trying to abandon the group.
• You Are Better Than You Think You Are: She tells Senya this after learning he still blames himself for her father's death.

• Curb-Stomp Battle: Dishes one out to an entire army while trying to be killed.

• Master Swordsman: Effortlessly cuts down dozens of samurai while trying to be killed, and has been stated to be capable of annihilating an entire army if he so chose.

Yamato Takeru

• Secret Test of Character: Tests Senya's resolve with a series of Armor Piercing Questions.
• Synchronization: All twins born with a Fairy Eye are linked forever. If one of them dies, so will the other. As Jinka is shown with an eyepatch in the finale, it's implied he (and by extension Takeru) got rid of the Fairy Eye so they won't be linked this way anymore.
• Talking the Monster to Death: He talks the two subordinate Tribe of the Void members into sitting down and talking things out rather than fighting.

• Big Good: While her motives are ambiguous, she's as close to one as the series has.

• Cartoon Creature: Looks like a cross between a cat and a squirrel with a forked tail.

Demons

Mudo

• Arrogant Kung-Fu Guy: He touts himself as unrivaled, especially against people calling themselves masters of their fighting style. He doesn't like to bow down to other martial artists unless they gain his respect, which an Old Master advises him to avoid doing when he's on the search for a master.
• Blood Knight: His purpose is to keep fighting until he is the strongest demon in existence. A Mudo in a fight of equals is a very happy Mudo.

• Villainous Crush: When he first appeared as an antagonistic figure, he gained one on Tsukiko.
• Walking Shirtless Scene: While most other men wear a proper kimono, Mudo slips by wearing a sleeveless vest and not much else.

Tago

• Butt-Monkey: Mudo pelts him with rocks to shut him up and Tsukiko easily defeated him with a bamboo sword.

• Dirty Coward: Will not hesitate to flee if the odds are against him.
• Dishing Out Dirt: Merged with a boulder to take on human form.

• Mr. Exposition: His special ability allows him to access information about any person, allowing him to spill the bens about Senya's pre-amnesia circumstances in an attempt to separate him from Shinsuke.
• Powered Armor: He shows up to the final battle against the Tribe of the Void wearing a mini-mecha of sorts, looking to pick a fight with Senya. Mudo gets him to transport the brainwashed orangutans out of harm's way instead.

• Stomach of Holding: Keeps a notebook and a wakizashi (which was stolen by Tsukiko) in his stomach, both of which he's named after himself.

Setsu

• Hopeless Suitor: While Setsu wants to be more than friends with Senya, he remains loyal to Tsukiko even long after his beloved wife's death. All of the immortals do see her as something of a mistress for Senya in the finale, since he often goes to her domain and they keep in touch on an infrequent basis.
• An Ice Person: As a yuki-onna, Setsu has full domain over ice powers.
• Rescue Romance: After Senya awoke her from her madness and saved her from a fire demon, Setsu fell head over heels for him to the point where she completely switches sides.

• Big Bad: He is the primary antagonist of the first arc.
• Brilliant, but Lazy: He's extremely intelligent but lacks motivation beyond his experiments.
• Combat Pragmatist:
  • Knows that he has no way of going up against the pissed-off Mountain Goddess, and would rather run away than stay and fight.

  • He uses the final battle with the Tribe of the Void to escape captivity.
• Enemy Mine: He and Kuzunoha end up in the care of the Mountain Goddess.
• Even Evil Has Loved Ones: He fell in love with Kuzunoha at first sight, and would rather let Taizan rampage and destroy his lab rather than risk revealing her to the Dangaishu.
• Evil Genius: Say what you like about him, but Yazen has came up with plenty of nifty inventions - the most prominent being human-demon fusion.
• For Science!: His experiments are directed towards turning Kuzunoha into a human. The human transformation? That's just a byproduct of it.
• Love at First Sight: He fell in love with the kitsune Kuzunoha, and betrayed his fellow monks to be with her.
• Scare 'Em Straight: To Tago in a roundabout way, who gives up his evil ways after Yazen dies in a plague.

Jinun

Voiced by: Kenji Nomura

• Love at First Sight: He fell in love with a girl he met while saving her village from a youkai, to the extent that his mission report was nine tenths him gushing about how beautiful she was. This girl, Chiyo, would later become the woman he initially leaves the Dangaishu for, his wife, and Senya's mother.
• My Greatest Failure: His failure to protect his wife was what led him to rejoin the Dangaishu and offer his young son up for experimentation.
• Not Distracted by the Sexy: Wasn't affected at all when a Tanuki - in the form of a pretty woman - ripped her clothes off.

• That Man Is Dead: After the village he lived in and his wife were killed, he swore off his old name of Kumozou.
• Unable to Cry: He wasn't broken up when his parents died, didn't shed a tear when his wife died, and couldn't muster up the will to cry when he recognizes what's been happening to Senya. Only after he gets defeated by Douren in their final confrontation together does he allow himself to cry over all of the hardships in his life.
• Worthy Opponent: Sees Jinka as this. He's also inwardly impressed by his son's growth, and willingly sides with the Tribe of the Void to see how powerful his son has become.

Douren

Voiced by: Tetsu Inada

• Attack! Attack! Attack!: No-one can accuse Douren of subtlety.

• No-Sell: He has no weakness in his heart for the Tribe of the Void to control.
• Older Than They Look: Yazen has stated that both Jinun and Douren were the same age as him. Fusion with demons may have slowed down the effects of old age.

• Rapid-Fire Fisticuffs: His ultimate move is essentially summoning his own fist in order to launch a flurry of punches.
• Super Mode: He can transform into an anthropomorphic tiger.
• Taking the Bullet: Douren took a hit from Nadare until the control of the Clan of the Void to prevent him from hitting the monkeys and Mudo.
• Tiger Versus Dragon:
  • Has an ongoing rivalry with Jinun (a man with heavy dragon motifs), and actually joined the Dangaishu because of this.
  • Eventually takes Mudo, another dragon demon who sees him as the only human worthy of fighting him like Senya, as a traveling partner.
• Weak, but Skilled: He was among the weakest compared to Senya and Mudo in the final battle in terms of spiritual power, but he was the best fighter.
• World's Best Warrior: The demon fused with him is strong, but not the strongest. He still beats up some of the most powerful fighters in the world through sheer skill, and even dragons want to apprentice themselves to him.

• Artificial Human: His body is made out of curses.
• Blood Knight: He enjoys killing more than anything else.

• Ninja Pirate Zombie Robot: Has a body made out of curses, and carries around a bag that can spew out anything. Towards the end of the first arc, Resshin has been modified by Yazen so much that he resembles a giant tank. Subverted by the fact that Yazen states that Resshin is "nothing more than a heap of trash glued together".
• The Only One Allowed to Defeat You: He takes this view towards Shinsuke.
• A World Half Full: Possibly views the world this way, given this quote: "I love being free to kill and kill all I want, for this world is already half rotten!"

Higan

• Alas, Poor Villain: Is set up as a traitor and executed by Resshin.
• Dishing Out Dirt: She was fused to a rock demon.
• Even Evil Has Loved Ones: Dearly loves her brother and did everything to make him happy.

• Advanced Ancient Humans: They lived thousands of years in the past, but possessed technology capable of altering probability. When the older twos' bodies are shown, they're wearing modern-day clothing.
• Battle in the Center of the Mind: The secret of the making of Mad Gods—theyy drive their victims to madness by invading their mental worlds and take on the shape of their strongest foes.
• Big Bad: Of Part 2, as they go around driving gods insane.
• Evil Counterpart: The leader decides to make himself one to Senya, creating his own Brainwashed and Crazy Parade of 1000 Demons to rival Senya's.
• Genre Savvy: Their leader realizes that Senya is a Shounen Protagonist that fate decrees win in one-on-one combat so they plan to raise an army so that he dies in an epically flashy manner.
• Gone to the Future: They are Senya's ancestors from a time long past, and their goal is to save their people in the future.
• Greater-Scope Villain: In Part 1 they are the cloaked figures who pop up intermittently.
• Hellish Pupils: They have slitted pupils, one of which is white.

• Killed Off for Real: Senya kills two of the five in his first battle with them.
• Kill the God: What seems to be their current objective, as they are sicing Jinka on various deities and turning the ones they find useful into psychotic slaves.
• Let's You and Him Fight: Intend to pit Senya against Jinka in order to obtain the Jewel of 1000 Wonders embedded in his body, and use it and Jinka's power to change the fate of their homeland. It just so happens that the act will kill them both.
• Living Shadow: Their bodies are made up of tattered scraps of darkness in the shape of human bodies.
• Magical Eye: They have the Fairy Eye, like Jinka.
• Master of Illusion: They can take on the appearance of anything and anyone.
• Mind Rape: What they do to create Mad Gods, and even possess minor demons.

• No-Sell: They walked through Jinka's attacks like they weren't even there during his fight with Douren.
• Scarf of Asskicking: The youngest member - who is also their leader, wears a scarf made of the same darkness as his body. Though technically it's more that the others allow him to call the shots.
• Screw Destiny: Their goal is basically to use Senya's spiritual core as a means of altering Fate to make the meteorite that hits their nation miss it instead. As it turns out, this is the exact reason why the meteorite is there— all of their previous meddling with fate has made the will of the universe come up with disasters designed to pay them back in full.
• The Slow Path: The scarf-wearing one decides to search throughout time to find a way to save their people.
• The Smurfette Principle: Only one of their members is a woman.
• Talking the Monster to Death: Ultimately, a good and long discussion is all it takes to get them to back down.
• Theory of Narrative Causality: The "fate power" they seek to harvest from Jinka and Senya is essentially the power to be the protagonist of a story. They set up a grand Final Battle for Senya precisely because since he has so much fate power, attempts to defeat him in an anticlimactic way are doomed to fail.
• Walking Spoiler: Gee, you think?
• Well-Intentioned Extremist: They want to save their nation and that just so happens to mean the death of Senya and Jinka. To that end, they even consider their own lives expendable.
• White Hair, Black Heart: Their hair is silver, and they are the main villains of Part 2.
• Winds of Destiny, Change!: Their ancient civilization - wiped out by a meteor - had the technology to alter probability using the fate power from singularities of spiritual energy. It was their abuse of this power that wound up summoning the meteor that destroyed them.
• You Can't Fight Fate: The older two learn this the hard way and return to their nation, though Senya informs them that he is a descendant of theirs, so at the very least their bloodline survives. The younger one decides to continue walking the time-space continuum searching for a solution.
