The characters of Descendants of Darkness:
- 100% Adoration Rating: Even the villain loves this guy!
- Ambiguously Bi: Is very frequently attracted to women, but also enjoys flirting with and teasing Hisoka on occasion.
- Attractive Bent-Gender: In the storybook arc. Even Tsuzuki thinks that fem!Tsuzuki looks good.
- Chronic Hero Syndrome: Tsuzuki has the unfortunate tendency to try to help every suffering person he meets, usually at the cost of personal well-being.
- Despair Event Horizon: When he (unwittingly) killed people back when he was alive.
- Even the Guys Want Him: Tatsumi and Watari get accidentally turned on by him when he strips out of his yukata for a bath, The Count has been dogging him for years, Muraki has an unsettling fixation on him, and Hisoka turns Tsundere at the drop of a hat around him.
- Interrupted Suicide: The second time he tries to kill himself, Hisoka snaps him out of it.
- Not So Different: With Hisoka. They were both ostracised, abandoned, and called monsters as children.
- Puppy-Dog Eyes: Even Tatsumi can't resist.
- Purple Is Powerful: He controls 12 shikigami, where the average shinigami is only able to control 1-3. On top of that, he's proficient at using ofuda, along with physical combat - if slicing out Muraki's eye is any indication. Physically, he's able to crack bulletproof glass by punching it with his bare fist. It's heavily implied all of these abilities have a connection with his purple eyes.
- Really 700 Years Old: Tsuzuki physically stopped aging at 18, lived on until his death at 26, and then worked the last 70 years in the Shokan division.
- Sexy Priest: When undercover at a catholic school.
- Taking the Bullet: For Hisoka, more than once.
- Trademark Favorite Food: Apple pie.
- What Beautiful Eyes!: His bright purple eyes are noticed in-story as strange, especially by Muraki.
- You Are Not Alone: Has to be reminded of this whenever he falls into depression, usually by Tatsumi or Hisoka.
- Abusive Parents: His mother and father locked him in the cellar ever since they found out about his powers. Physical abuse is not touched on, but his mother fervently believed he was a demon. He was disclaimed as her child.
- Actually, one of Hisoka's flashbacks-presented-as-nightmares features other village children asking him "Did your mother hurt you again?" This implies there was physical abuse, and that it was common knowledge to at least the other children.
- Ambiguously Bi: Develops feelings for Tsubaki, but also reacts tellingly whenever Tsuzuki teases him.
- Blessed with Suck: His empathy powers are useful, but can just as eaily make him disoriented or even cause him to pass out.
- The Cutie: Even (or especially) when he's being tsundere.
- Kill the Cutie: He is a Shinigami. The cruelty of his death and his suffering before and afterward make it no better.
- Cooldown Hug: Gives a couple of these to Tsuzuki throughout the Kyoto arc.
- Covered in Curse Marks: His death-curse is etched all over his body, though it comes and goes at times. It's implied that even thinking about Muraki will cause the marks to appear on Hisoka's body.
- Crazy Jealous Guy: Comes across as this in the drama CD when he walks in on Muraki molesting Tsuzuki.
- Cruel and Unusual Death: Muraki raped him when he was thirteen and then cursed him to die slowly and painfully over the course of three years. Ouch.
- Dark and Troubled Past: Ever since his parents caught wind of his emphatic abilities, Hisoka had been forced to spend an enormous amount of time locked in the cellar of his home for using them. Moreover, it is his empathy that forces him to feel the emotions of others whether he likes it or not. Even after Hisoka becomes a Shinigami, the thoughts and emotions of others—or particularly gruesome visions—could overwhelm him and send his brain into overdrive.
- Muraki raped him at the age of thirteen and then cursed him to die slowly and painfully over the next three years after Hisoka manages to get outside for the night and witness him murder a woman. Hisoka could have died quickly enough, but Muraki wanted to draw things out. His reason? Because Hisoka was so beautiful, his death had to be 'special'.
- Declaration of Protection: Has a variation of this toward Tsuzuki. He swears that even should everyone else disappear from Tsuzuki's life, he'll stay by his side.
- Distressed Dude: Falls into this occasionally.
- Family Theme Naming: All the members of his family have an aquatic name. Aside from "secret," the character for his first name (密) is more commonly read as "dense."
- Heterosexual Life-Partners: With Tsuzuki, although the heterosexual part is up for debate.
- Honor-Related Abuse: Locked in a cell after being declared a monster for his empathy, something the family found shameful.
- Ill Boy: Even in the afterlife, he encounters side-effects from his empathy (being in large crowds and/or witnessing a particularly gruesome vision) and curse marks (whenever Muraki is nearby). Hisoka is also extremely sensitive to the sun and he can't hold his liquor well at all.
- "It" Is Dehumanizing: On top of being labeled a monster, he's literally referred to with "it."
- Luminescent Blush: Several times, and usually in response to something Tsuzuki says/does.
- Meaningful Name: The characters in Hisoka's full name (黒崎 密) translate to "Kurosaki secret" when put together. Considering he spent the majority of his life hidden away in a cellar, that's rather apt.
- It gets more depressing when you consider it was originally his older sister's name, and all first born girls are killed, implying Nagare would have kept her alive as his "secret" if he could have.
- Another way the kanji of his given name could be read could be "dense," or "density." Considering the Kurosaki clan's Family Theme Naming regarding liquid in some manner, it could be very loosely related to that.
- Mr. Fanservice: All the girls go wild when he enters the scene.
- Not So Different: With Tsuzuki. They were both ostracised, abandoned, and called monsters as children.
- Please Don't Leave Me: Begs Tsuzuki not to leave him all alone again when Tsuzuki tries to kill himself. It works.
- Power Incontinence: Sometimes Hisoka can't control his power to absorb emotions and he passes out.
- Together in Death: Tries to invoke this with Tsuzuki at the end of the Kyoto arc, at least in the manga, since he can't bear the thought of being alone again. Tatsumi saves them both.
- Undying Loyalty: To Tsuzuki.Hisoka: Even if everyone else in your life disappears, Ill always be here by your side.
- You Are Not Alone: Constantly has to remind Tsuzuki that he's there for him, even if Tsuzuki isn't receptive to the comfort. Tatsumi actually implores him to stay with Tsuzuki, and Hisoka decides that even should everyone else turn their back on Tsuzuki, he'll always remain by his side.
Chief KonoeTsuzuki and the others' boss, the Father To His Men Chief of the Shokan Division.
Seiichiro TatsumiChief Konoe's Sexy Secretary at Enmacho who terrorizes the division about expenses and work. He used to be Tsuzuki's partner.
- Berserk Button: Hurt Tsuzuki and you will pay.
- He gets a pretty crazed expression when he promises Tsuzuki he won't let anybody harm Hisoka, too.
- Calling the Old Man Out: He does this to Nagare in Hisoka's stead."Does your house... your land... your tradition mean so much to you? So much that you'd let your own son die without seeking treatment?!"
- I Want My Beloved to Be Happy: Toward Tsuzuki. He implores Hisoka to take care of him after he failed to do so, and during the storybook arc his counterpart character outright states this toward Tsuzuki's counterpart. Keep in mind that the characters in the book share the thoughts and feelings as their real counterparts.
- My Greatest Failure: Letting Tsuzuki go.
Yutaka WatariThe division's resident quirky Mad Scientist.
- Gadgeteer Genius: Though sometimes his inventions just blow things up.
- Nightmare Fetishist: In the dub, at least, he sounds WAY too enthusiastic about murder victims and demons.
Kazutaka MurakiEveryone's favorite Creepy Awesome Stalker with a Crush Deadly Doctor. The main antagonist of the series.
- Badass Normal: Muraki doesn't actually have powers the way the shinigami do, so it's astonishing that he's been able to give them so much trouble.
- Beauty Is Bad: How many characters who've said that Muraki looks like a white angel have died horribly?
- Big Bad: Especially in the anime, where there's only one arc where he isn't directly responsible for the horrible things everyone goes through.
- But for Me, It Was Tuesday: Hisoka remembers vividly the horrible things he did to him but it's just another day in the life for Muraki.
- The Corrupter: Let's see, how many lives has he ruined now?
- Depraved Bisexual: Though he denies that he's gay, Muraki acts pretty disturbing whenever he's with Tsuzuki...
- Devil in Plain Sight: Please. He totally does not look like an angel.
- Hero Killer: In a sense. He killed Hisoka but hasn't "killed" any of the shinigami, who are already dead.
- Karma Houdini: He really doesn't get justice for all of the horrible crimes he's committed.
- No Sense of Personal Space: Especially toward Tsuzuki and Hisoka.
- Post-Rape Taunt: Does this to both Tsuzuki regarding Hisoka, and Hisoka himself.
- Slimeball: A handsome one, but a slimeball nonetheless.
- Smug Snake: Driven home by the dub, where his voice has a smugly superior sounding tone to it.
- Would Hurt a Child: Hisoka was thirteen when Muraki raped, tortured, and murdered him. Muraki also kidnapped a flower girl to traffic her organs, and stole energy from a little girl to get Tsuzuki's attention.
- Would You Like to Hear How They Died?: Asks this to Tsuzuki regarding how he murdered Hisoka.
Saya Torii and Yuma Fukiya
- Ship Tease: With Terazuma.
- The Smurfette Principle: The only named female who besides Saya, Yuma and Suzaku who appears multiple times and doesn't suffer a gruesome death.
- Ridiculously Cute Critters: A plucky duo of tiny birdlike creatures.
- Chivalrous Pervert: Toward Tsuzuki.
- Single-Target Sexuality: Toward Tsuzuki.
- Driven to Suicide: Committed suicide because of how much her mother used her. Her mother made a deal with Muraki to bring her back.
- Evil Diva: Appears to be one, though it turns out that she's not exactly "evil".
- Abusive Parents: Manipulated and controlled Maria to exploit her wealth and fame. After the stress drove Maria to suicide, her stepmother asked Muraki to bring her back so that she can exploit her more.
- All Take and No Give: Her relationship with Maria.
- It's All About Me/Skewed Priorities: Her reaction when her stepdaughter commits suicide? It's basically "how can I exploit my daughter if she's dead!?
- Kick the Dog: Forcibly bringing her daughter back to life despite the fact that Maria was happier being dead.
- Affectionate Nickname: Kazusa calls him "Hi-Chan".
- Demonic Possession: A victim of it, due to the eye that he was given.
- Driven to Suicide: Sort of; he tries to kill himself after everyone around him starts seemingly developing a Hate Plague and even Kazusa becomes scared of him (she actually sees the demon lurking within him), but Tsuzuki is sent to save him.
- Elegant Classical Musician: He's skilled with the violin. This drives the plot of his arc.
- Intergenerational Friendship: An adorable one happens between him and Kazusa.
- Precocious Crush: Seems to develop one on Tsuzuki by the end of his arc.
- Twin Switch: They're not twins, but Hisoka and Hijiri are identical enough to switch places so that the demon possessed Tsuzuki kills Hisoka instead of Hijiri, who is placed in hiding with Kazusa.
- With Great Power Comes Great Insanity: His possession by the demon.
- Adaptation-Induced Plot Hole: In the anime, she dies offscreen and yet somehow comes back to watch Hijiri's performance, with no explanation. In the manga, she sort of becomes a shinigami (most likely because her True Sight would prove useful), which is explained to Hijiri in the hospital scene (a scene the anime cut her out of).
- Back from the Dead: Kind of. She's still dead, but now she's a shinigami!
- Companion Cube: Carries a teddy bear around. It disappears later, though.
- Conveniently an Orphan: Turns out that her father's death was NOT a coincidence...
- Cute Ghost Girl: Basically, after she dies.
- Dropped a Bridge on Her: More like Dropped a PILLAR on Her.
- Heroic Sacrifice: Pulls one to save Hijiri.
- Infant Immortality: ...is what she doesn't have.
- Mysterious Waif: A minor example; she was suddenly orphaned, she's being pursuied by a demon, can somehow see its true form and invokes a protective impulse in the main characters.
- True Sight: Can see the true forms of demons.
- What Happened to the Mouse?: After she dies, her soul is brought back and Hisoka promises Hijiri that they'll look after her. She is never seen again afterward. She does appear in a flashback in the anime, though.
- While she doesn't make an appearance herself, her toys are shown strewn around Tsuzuki's room later on in the manga, they actually are looking after her on a personal level.
- I Cannot Self-Terminate: So she asks Hisoka to do it for her. He takes it pretty well.
- Ill Girl: She has a very, very weak heart...
- Innocent Flower Girl: Which makes all the horrible things that happen to her all the more heartbreaking.
- Split Personality: Develops this thanks to Muraki's manipulations. She occasionally thinks that she's Eileen.
- Unwitting Pawn: For (surprise, surprise) Muraki.
- Innocent Flower Girl: Before being murdered and having her heart literally stolen so it can be given to Tsubaki.
- Only Friend: She once was this to Tsubaki. Poor Tsubaki did NOT take Eileen's fate well.
- Posthumous Character
- Affably Evil: The term "evil" only applies because he's allied with Muraki. For the most part, he's polite and amicable, and even gives Hisoka a fighting chance to save Tsuzuki.
- Friend to Psychos: When you're best bros with Muraki, this is kind of a requirement.
- Heterosexual Life-Partners: With Muraki. This being "Yami no Matsuei", however, the term "heterosexual" should be used very, very loosely.
- Red Oni, Blue Oni: Ironically, given their choice in clothing, he is the blue to Muraki's red.
- Ship Tease: He really seems to like Muraki.
- Big Bad: Very likely this.
- Giant Flyer: A huge phoenix.
- Mama Bear: To Tsuzuki, especially in the Kyoto Arc where she attacks a girl-turned-monster that Muraki sent to kill Tsuzuki with. Unfortunately, this leads to Tsuzuki losing his mind and going catatonic. Lampshaded by Tatsumi, who compares her protectiveness to a mother bird protecting her chicks.
- Nice Job Breaking It, Hero!: See Mama Bear above.
- Undying Loyalty: Taken to the extreme in the Kyoto Arc, where she remains loyal to Tsuzuki even after he loses his mind (something that would normally lead a shikigami to abandon or try to kill their master).
- Smug Snake: A literal serpent example. Boasts about being strong, but was slayed by a human. Is currently trapped in the Kurosaki bloodline, and still treats Nagare with disdain.
The whole family
- Family Theme Naming: The Kurosaki clan names it's members with a water motif. With one exception... Note: Sometimes the kanji can merely be read with the verbal pronunciation of the meaning rather than the literal kanji used having it. It's common in Japanese to ask the way someone's name should be read, since the pronounced word can have a different number of kanji, and therefore a different number of meanings.
- Would Hurt a Child: They drown all females born into the main line as a law.
- Jerkass: Had a second son on purpose to sacrifice specifically to spare his first, with possible intentions for his sons' blood feud to cause Yato to be released, the bloodline to end, and Kamakura to be destroyed.
- Meaningful Name: His name is just barely visible on the family tree scroll. It translates to "ocean," or "sea."
- Driven to Suicide: After Iwao killed her baby, she drowned herself in grief.
- Or, at least, that's what everyone's led to believe... until Iwao starts specifically denying he killed her as well as the baby. It's key to note Nagare had not accused him of murdering her... but still feels a need to deny it.
- Meaningful Name: Hers can be read as "sink," or "drown."
- Monster from Beyond the Veil: It appears she's been revived after death... but not like she once was.
- Youkai: It appears she is now a nure-onna.
- Snake People: A nure-onna is a woman that resides in water, who has a snake tail. She also often is depicted with a baby.
- Jerk Ass Has A Point: While it's awful he committed infanticide, it's to uphold a "clan law" that there can't be a girl born as the head of a new line. There's probably a reason for this rule, such as a female head getting pregnant with the new vessel for Yatonogami... like Rui currently is.
- Meaningful Name: Iwao is the only member of the Kurosaki whose name does not fit the water motif. His name roughly translates to "rock." One of these things is not like the others...
- Relative Button: Iwao presses it by murdering Nagare's daughter, stealing her remains, then admitting it and calling her a "useless thing" to Nagare's face. With vehement denial on something Nagare hadn't accused him of, Iwao implies he may have been responsible for Kasane's death as well.
- Abusive Parent
- Driven to Suicide: Attempted, at least. Tatsumi finds him before he bleeds out.Nagare, crying: "This time, I thought I could go where Kasane and the children are..."
- Divine Date: Sexually involved with a god, though not by choice.
- Fate Worse than Death: As head of the clan, he's a living sacrifice to a god to keep it trapped. It involves being raped with tentacles, implied to be a daily affair, along with coughing up copious amounts of blood and losing eyesight. It's so bad Nagare nearly kills himself out of spite, to inflict this fate on Iwao.Nagare, to Iwao: "It's not that you can't be head. It's that you will never be head."
- Gratuitous Rape: There's an entire scene devoted to depicting Yatonokami violating Nagare. It's speculated as one of the reasons the series went on hiatus - Matsushita was essentially drawing tentacle hentai in a manga series aimed at teenage girls.
- Honor-Related Abuse: It's established as shameful for Iwao that Nagare inherited position of clan head as a younger brother and therefore not having a birthright to it. Out of revenge for this slight, Iwao murders Nagare's baby and possibly his wife, and goes on to convince people that acknowledge Nagare is their friend that he deserves to have his child's grave desecrated, and to be murdered.
- In his monologue regarding his past, he also says he strived to be "worthy of the honorable name Kurosaki," and is overjoyed to be declared head. It was all a ploy. His father was just using his drive to uphold this honor to make him a sacrifice.
- While being raped, Yato insults him in various ways... but what hurts him the most is when his ancestors' honor is insulted.
- Jerkass Woobie: Nagare has done bad things... but man has his life been awful.
- He was born specifically to be a sacrifice replacement for his brother, this was revealed to him after a lifetime of trying to please his father and fit in with the family, he lost his beloved wife and daughter in the same short timespan, he wasn't allowed much time to grieve them before being forced into marrying her twin sister, his baby with her was labeled a monster and his new wife tried to kill him, he was called a coward for not killing Hisoka himself, his son was murdered, his own brother is slandering him to the point people who acknowledge he's their friend are willing to conspire to murder him, his brother desecrated his daughter's grave... oh, and did I mention he gets tentacle raped on the daily by a vengeful god that's destroying his body from the inside out?
- Karmic Rape: Some folks might find being raped a good punishment for committing child abuse.
- Meaningful Name: The kanji for "Nagare" (流) can be read as "flow," "stream," and "current." He has a water serpent inside of him.
- He and Rui match; together their names be can be read as "flowing tears."
- Mind Rape: It's speculated Yato having his way with him could be an example of this; physically, when Tatsumi barges in, Nagare's still got his kimono on (someone cannot tie their obi - the sash at the waist - on their own at the back, but it's intact on him), and there's nowhere near as much blood on the floor as he was previously shown coughing up.
- Naughty Tentacles: He doesn't just experience rape. Oh, no... it involves tentacles.
- Technically, they're Yatonokami's numerous tendril-like tongues. But they serve the same purpose in this context.
- Rape as Backstory: For the past 20 years. And still happening.
- Rape Leads to Insanity: Nagare presents symptoms of PTSD directly after his rape scene. He gets a thousand yard stare, absentmindedly licks blood and some other kind of fluid off of his hand, then proceeds to strangle Tatsumi when reminded of the traumatic loss of Kasane. Unhinged for sure.
- Relative Button: His daughter was murdered and her remains were stolen by Iwao - who goes on to gloat he was doing the right thing per clan law and call her a "useless thing" as a form of this. Iwao also keenly mentions he "wasn't" responsible for Kasane's death. Nagare hadn't accused him of that.
- "Well Done, Son!" Guy: In his monologue, he outright states he put effort into becoming someone worthy of the Kurosaki clan. He was pleased when his father declared him heir, since he took it as a sign he was finally accepted by he predecessor.
- Family Theme Naming: It all started with him, when he founded the Kurosaki clan. To this day the family uses water motifs as a naming convention.
- Meaningful Name: His translates to "lotus," and he slayed a water serpent. Lotuses float on top of water. The family crest, incidentally, is a lotus.
- The Hero: To this day he's revered for saving Kamakura by slaying the great serpent Yatonogkami. Most people think it's a mere legend, but it's not.
- Angsty Surviving Twin
- Honor-Related Abuse: She's being held in the family confinement room to hide her pregnancy so as not to taint the family honor.
- Laser-Guided Karma: Rui disowned Hisoka as her son because he was "a demon"... and as of the current arc, she's been suffering with an actual monster in her womb for years.
- Longest Pregnancy Ever
- Meaningful Name: The kanji for her name can be read as "tears," or "cry." She has a lot to cry about; her twin sister died, she was brought in to replace her sister, her husband doesn't seem to be in love with her, from her perspective she gave birth to a monster, and she's currently pregnant with one.
- Replacement Goldfish: She is a replacement for her twin sister.
- Twin Switch: Sort of. Technically not quite, considering she's a replacement for her dead twin.
- Would Hurt a Child: She used to beat Hisoka, in an active attempt to kill him.Rui, with an unhinged expression: "I'll kill it [Hisoka] with my own hands."
