Riku Amami
Jinki Form 
Voiced by: Junko Minagawa

Riku is the story's protagonist and a high-school student who lives with his father (absent for most of the story) and stepmother, Shizuru. He was in love with Shizuru's younger sister, Amane, but she is presumed to have died two years ago in a fire at Kazama Hospital. He receives a text message from her phone address and goes to the place of her death, providing the setting for the start of the series.

After sustaining, near start of the series, a fatal wound from a Kanshuu, Neene turns Riku into a special Kanshuu that can retain his own consciousness as long as he has a Jinki.
  • Zero-Approval Gambit: He's done a few. All justified. By having the people's hatred focused on him, his allies can focus on saving the world.
  • Affectionate Nick Name: He is called "Ricchan" by his family.
    • Clara and Joe call him "Rikkun/Rick".
  • The Atoner: After Neene's death and the memory trip, he seeks to atone for his lies.
  • Bifurcated Weapon: Part of his sword detaches into a smaller dagger after he gains a second Jinki core.
  • Big Sister Attraction: He was in love with Amane, his step-aunt, whom he considered as an older sister.
  • Cool Sword: Chainsaw sword... with attachable baton. At the end of the series, he gets a laser one to replace it.
  • Consummate Liar: He considers himself to be a great liar.
  • Chainsaw Good: A feature of his sword.
  • Earn Your Happy Ending: Dear sweet lord does he go through a lot! It even takes a Zero-Approval Gambit to get Rena's "memories" back and restore her. He's earned his Tears of Joy when it's all over.
  • Facial Markings: When transformed.
  • The Glasses Come Off: When transformed. A Justified Trope, as the Jinki transformation corrects his vision. Upon gaining Nanami's Jinki core, the effect becomes permanent even when the Jinki cores aren't active, eliminating his need for glasses entirely.
  • Heroic B.S.O.D.: Several, all justifed.
  • Impaled with Extreme Prejudice: Repeatedly.
  • Impossibly Cool Weapon: Chainsaw Sword. Best weapon ever.
  • Locked into Strangeness: After getting his second Jinki core his hair stays white.
  • Megane
  • Missing Mom: His real mother died when he was a young child.
  • Nice Job Breaking It, Hero!: Let's just summarize this entry by saying that the world is not kind to Riku... Not at all.
  • Not So Different: From Shirou Karasawa.
  • Only Mostly Dead: It's amazing how many times he's "died" only to show up again later.
  • Papa Wolf: Don't mess with Neene! He not only sees her as his daughter, but he treats her as such, and he's extremely protective of her. Whatever flaws he may have, he's the one only one in the entire story to treat a coffin princess properly, like a human being, and actually care for her openly.
  • Power Dyes Your Hair: His hair turns completely white save for two strands of hair that turn red.
    • Becomes permanent after getting his second Jinki core.
  • Slut-Shaming: On Sawako. Justified.
  • Spell My Name with an "S": Or rather, the alias he earned through infamy on the net. Earliest translations rendered it as the unaltered romanization "Suraga." Another came up with "Slager." And yet another interpreted it as a transliteration of the word "Slugger," which may be the most appropriate due to his fighting style when he first received his Jinki.
  • Supernatural Gold Eyes: Only when he transforms.
  • Superpowered Evil Side: When he was infected.
  • Super Senses: Part of the C.A.G.E Package
  • Take My Hand: Four times, all beautifully done.
    "There had been 3 people (Rena, Youhei, Takao) who grabbed my hand... But she Rena was the first one whose hand I grabbed."
  • The Tell: He has a habit of licking his lips a little when he lies. For obvious reasons, he gets periodic close-ups on his mouth.
  • Unresolved Sexual Tension: With Rena, obviously.
  • Unstoppable Rage: When he gets pissed, he's almost unstoppable.

Rena Arisugawa Ootori
Jinki Form 
Voiced by: Kana Asumi

A young Jinki user who is depicted as a quiet and serious person focused on her job, who frequently takes the lead when fighting Kanshus. After Youhei's death, she becomes Riku's partner, whom she appears to have become attracted to, after their meeting with the Source of Infection. She is a Lost Rebound victim; her entire family was killed in Hatsumi Island during the original infection and became Kamogari.

Grown Up 
Voiced by: Chiwa Saito

Neene was hatched from a cocoon at the start of the story, and grows at a rapid rate, experiencing a growth spurt occurring each time she uses her powers in a Kanshuu fight. A mysterious entity who has an uncanny resemblance to Riku's dead aunt Amane. Neene recognizes Riku as her "papa" and later Rena as her "mama".

As the series progresses, she demonstrates various powers, such as turning Riku into a Kanshuu after he is wounded in a fight and creating a giant ball of light that disintegrates anything inside it. She is eventually revealed to be a Kyuuki/Coffin Princess, a queen Kanshuu who receives the memories stolen by other "drone" Kanshu, and she grows as she absorbs more memories.
  • The Cutie
  • Daddy's Girl: Neene. Played for laughs. Later also Mommy's Girl with Rena.
  • Famous Last Words: "Liar".
  • Happily Adopted: By Riku, who becomes her papa. She later "adopts" Rena as her mama.
  • Heroic Sacrifice: Neene sacrifices herself to stop rampaging Ende, and was narrowly saved by Amane. Made more poignant with her calling Riku a liar, while it is clear that he has begun to sincerely care for Neene, not just as Replacement Goldfish for Amane.
  • Identical Stranger: She strongly resembles Amane, prompting people to think that she must be Amane's daughter or at least a close relative. The truth is that her nature as a Kyuuki means that she is actually Amane, or more exactly that she will become Amane.
  • Plot-Relevant Age-Up: Neene grows faster than a normal child. She ages as she absorbs memories, otherwise her growth rate is akin to that of a normal human.
  • Replacement Goldfish: Takao tells Riku that if he raises Neene she'll grow up to become Amane. But as the story advances Riku begins to care for Neene as just herself, "his daughter", and not as a replacement for Amane.
  • Rose-Haired Sweetie
  • She Is All Grown Up: After a three months Time Skip after her supposed death she appears to have grown older, looking the same age as Amane, in fact it may be because Amane's ego has woken up.
  • Shipper on Deck: Riku is her papa and Rena is her mama.
  • Sprouting Ears: Neene does this at crucial moments. Normally they are also present, but closed.
  • Supernatural Gold Eyes
  • Token Mini-Moe: When she's a child.
  • Younger than She Looks: She is born looking already like an almost two years old child. And as the story advances she keeps growing older, even though she should only be a few weeks old.


Shirou Karasawa
Voiced by: Toshihiko Seki

The main antagonist for the first half of the series, he was known as the Source of Infection that creates and controlled the Kanshuu. Shirou is the son of the elder Tokiji, who lived with his mother after a court case drove them away. When his mother died, he went to see his father but was denied the privilege. That day he met Sayoko Tokiji, who showed him kindness, and thus he fell in love with her. Since that time, he has also sworn to destroy his father, the head of Tokiji and worked his way into the company.

  • Affably Evil: He's pretty polite and only wanted Ende back, minus the whole Kanshuu spreading, killing people thing.
  • The Atoner: In his final moments...
  • Because You Were Nice to Me: He fell in love with Sayoko when they met each other as children since she was kind to him. After meeting again as adults he fell in love with her again.
  • Bespectacled Bastard Boyfriend: He is the man that Sawako was enganged to.
  • Big Bad: He is the "Source of Infection", meaning that he is the one who creates the "Kanshuus".
  • Body Horror: What his true form looked like after his last fight with Takao, it was not pretty.
  • Four Eyes, Zero Soul: He's a monster early on.
  • Bastard Bastard: He is the illegitimate son of a powerful rich man the Tokiji patriarch. He used to be leaning more towards the Heroic Bastard side of illegitimacy, but it all changed after his Start of Darkness.
  • Incest Is Relative: Sayoko and Sawako are his father's grandchildren... Which means that they are his nieces...
  • Intergenerational Friendship: Had a friendly relationship with Takao. Shirou was one of the few to be nice to him and Julie. He relied on Takao and trusted him a great deal. The boy's "betrayal" hurt Shirou enormously and he would later "get even" with him.
  • Love Makes You Evil: His love for Sayoko/Ende and his desire for revenge are his main motivations.
  • Revenge Before Reason: He wants to avenge Sayoko. Plus his original purpose was to get even with his father for discarding his mother and himself.
  • Start of Darkness: The Hatsumi Island incident.
  • We Used to Be Friends: He used to be friends with Ryuusei Takao.
  • Wicked Cultured: Carries this appeal.

The virus takes over the consciousness of the infected, effectively destroying it. Anyone that becomes or is killed by a Kanshu is forgotten completely, with few exceptions.


Takao Mishima Ryuusei Takao
Voiced by: Kentaro Ito

  • Abusive Parents: Well abusive grandfather in his case.
  • Affectionate Nickname: He was called "Ryuu-chan" by his mother/Julie and "Ryuu-kun" by Rena.
  • Adorkable: His interactions with Yui are quite funny and sweet.
  • Brutal Honesty: Given that he doesn't lie.
  • The Caretaker: For Julie, who despite possessing an adult body had the mentality of a child.
  • Dark and Troubled Past: Very dark, very...
  • The Dreaded: He is the Hunter of Jinkis after all.
  • Even Bad Men Love Their Mamas: He loved his mother (Yuri, and her Kyuuki, Julie) a lot and is still quite devoted to her. Technically he is not evil, but sort of an antagonist.
  • Forgotten Childhood Friend: He and Mitama/Rena were each other's only friend. He still remembers her, but she doesn't. Justified since Rena suffered from "Lost Rebound" so she doesn't remember him until she regains her memories.
  • He Who Fights Monsters
  • Hunter of Monsters: He only hunts Kanshuus and Jinkis, the latter he does it exclusively for their cores. Which were created from Julie.
  • Intergenerational Friendship: Used to be friends with Shirou, as he was of the few to be nice to him and Julie. He gave him information about the Kyuukis/Coffins Princesses and ultimately helped him bring Ende into this world. Sadly he eventually got caught by the adults of the village and was forced to "betray" Shirou.
  • Meaningful Rename: Ryuusei created the alias "Takao Mishima" borrowing the fake last name that Sayoko, his teacher, used.
  • Mercy Kill: To some of his "victims".
  • One-Man Army: Tears through Kanshuu and lesser Jinki-users.
  • Revenge Before Reason: His motivation is to find the "Source of Infection", his name being Shirou, and get his revenge on him.
  • The Stoic: Most times.
  • Serial Killer: How he is perceived by the rest of the world.
  • We Used to Be Friends: He used to be friends with Shirou Karasawa.
  • Will Not Tell a Lie: He decided to live by this principle.

An organization that fronts as a cell phone company, they handle the Jinki Users and Kanshuu incidents.

Sawako Tokiji
Tokiji Sawako is the Chairwoman of F.L.A.G. and one of the heirs to the Tokiji Company. In the past, she was engaged to a man called Karasawa, and she was pregnant with his child. After turning into a Kanshuu he was captured but he could apparently still control his mind, he talked her into releasing him by claiming he was in pain and then attacked her. The resulting injuries rendered her unable to bear children anymore, and she stated that the attack also killed the child she was pregnant with.

She became a manipulative woman, willing to drive Riku into a rage if it meant bringing an end to the Infection. She disappeared after Ende's attack and was hospitalized in a coma until fragments of Shirou returned her stolen memories.
  • Always Identical Twins: She and Sayoko were identical twins, the only way to difference them was Sayoko's scar.
  • Angsty Surviving Twin: She forgot about her twin sister Sayoko, given that her loss would be too much for her to handle.
    • When she finally remembers her she starts crying and exposes herself to a really dangerous situation.
  • Beauty Mark: Under her left eye.
  • Bitch in Sheep's Clothing: She's good at hiding it and Riku only saw through it at first with help from the "Source of Infection" Shirou.
    • She is not a bad person at heart, but she's determined not to make the same mistake as before to prevent more people dying like when she released Shirou. So she commits the exact opposite mistake, and it costs her dearly.
  • Defiled Forever: Since she lost her child and became unable to have more children, after the injuries she received when she was attacked by Kanshuu-Karasawa, she is treated like this by her grandfather.
  • Freudian Excuse: After all that happened with Karasawa, she decided that she would do anything to ensure that F.L.A.G. would find the "Source of Infection" destroy it and eliminate Kanshuus forever.
  • Incest Is Relative: Unknowingly to her she was in a relationship with her uncle, as Shirou Karasawa was her grandfather's illegitimate child.
  • Kind Hearted Cat Lover: She has TEN cats, and she ends up adopting the cat of a Jinki user who died.
  • Laser-Guided Amnesia: She doesn't have any recollection of ever having a twin sister, at first.
  • Poor Communication Kills: She alienates Riku by lying to him, a Consummate Liar, which makes him far more likely to see through it. To make it worse, she has people experiment on Neene without his knowldege or consent. To say that goes wrongly is an understatement of legendary proportions.
  • Replacement Goldfish: She was more or less this for Shirou.
  • Shameful Strip: Her grandfather has a truly depraved ritual that he puts her through every time she comes to visit him, especially if he summons her. He calls her to his bedroom, loudly and angrily demand that she disrobe, to expose the scar of her injury which rendered her barren, and then slut shames her before throwing her out again. Yeah, he's not winning any parent of the year awards. Mental illness or no.
  • Slut-Shaming: On the receiving end from both Riku and her grandfather. Her grandfather does it because he's mentally ill, and a dick. Riku does it because she not only pissed him off by experimenting on Neene which let "The Source of the Infection" contaminate and use More Than Mind Control on Neene, but then she goes and serves to enrage and disgust him even further by "offering to help him with his virginity" as he's cornered, and using her as a hostage.
  • Theme Twin Naming: "Sawako" and "Sayoko".
  • Trauma Conga Line: Sawako has had a rough time since finding out that her former fiancee was "alive". Not only didn't he even care about her, he openly mocked and scorned her and tried to kill her. Then, when she finally remembers the existence of her sister, Sayoko, and goes to confront Ende, hoping that she may recognize her... But Ende doesn't and she categorizes Sawako as her enemy and tries to kill her. This doesn't even account for what her grandfather puts her through, or what she brings on herself by pissing off Riku.
  • Unwitting Instigator of Doom: Twice. First she lets herself be tricked by Shrio, by being a bit too honest with him, then she makes the exact opposite mistake by outright lying to Riku and Neene. Both times go very, very badly.
  • Well-Intentioned Extremist: Karasawa has to be stopped, even if it means sacrificing someone else to do it.

Youhei Takebe

His Jinki resembles a short blade and was given to him by his teacher, to save him from Kanshuu-inflicted wounds. In an ironically similar situation, Youhei ends up entrusting his own Jinki to a wounded Riku. At his own request, he is beheaded by his old friend before he could become a complete Kanshuu.
