The First Five
As a whole
- Action Survivor: All of them have to think quick, or improvise on defending themselves in order to live and escape Heavenly Host. In fact they're the only ones that made it out alive until Blood Drive.
- Dark and Troubled Past: With the exception of Yoshiki, the rest of them had pretty normal lives. By the time Blood Drive occurs, everything they've faced so far, appears to becoming this for them. However, with how things turned out, this might be more notably towards Ayumi and Yoshiki, they both practically got the worst kind of ending for them out of everyone.
- Death by Adaptation: It can range from Satoshi, Yuka, and Yoshiki in the Tortured Souls ova, Satoshi, Yuka, and Naomi with the hinted possibly of Yoshiki and Ayumi eventually not too far behind in the Corpse Party: Musume manga to the light novel.
- Demonic Possession: Depending on which installment, but the only one so far who hasn't been succumbed to this is Satoshi Mochida.
- Despair Event Horizon: All of them can fall into this if on the way to a bad ending, or sometimes in the main storyline it can be inevitable for one of them to cross this. Should any of them do while trapped inside Heavenly Host, the darkening can cause them to be Brainwashed and Crazy. It usually never ends well.
- Driven to Suicide: It varies from adaption to situation, but most of them will cross this if they've had enough. You can avoid these, but others will still at least attempt it. Sometimes, they'll succeed.
- Kid Hero: None of them are even in their final year of high school, let alone Yuka who is fourteen years old. The oldest out of them, are Satoshi, Yoshiki, and Ayumi who are seventeen.
- Sanity Slippage: Any of them can fall into this if not careful, thus getting locked into a bad ending. On the other hand, this can still sometimes be inevitable, and you can only do your best not to let it end horrifying.
- Trauma Conga Line: As you keep going farther into the main storyline, the horrors they all witness only continue to go From Bad to Worse. Poor kids have no choice but to keep moving forward otherwise they'll continue to endure breaking broken even if they've this close from crossing into Despair Event Horizon.
- Voiced by: Hiro Shimono
- An Arm and a Leg: In Tortured Souls, he gives his own paper scrap to Naomi and uses Kizami's for himself. After he, Naomi, and Ayumi perform the ritual, the scene cuts to Naomi and Ayumi sitting back in the classroom, each holding one of Satoshi's severed arms.
- Badass Boast: His first appearance in the game has him, without a trace of fear, say he will rescue everyone. Which is pretty badass for a guy shaking from scary stories earlier and stuck in that school.
- Big Brother Instinct: A very strong case towards his sister Yuka.
- Clueless Chick Magnet: He attracts the attention of three girls - Naomi, Ayumi, and his sister Yuka. The Lighter and Softer spin off Sachiko's Game of Love; Hysteric Birthday 2U, jokingly adds Yui and Tohko. But he is, of course, Oblivious to Love as per the trope.
- Cowardly Lion: Yes, he's terrified. That doesn't stop him from doing everything in his power to find a way out for his sister, his friends, and himself.
- Death by Adaptation: In the Tortured Souls OVA and in Corpse Party: Musume.
- Deadpan Snarker: In Book of Shadow, it was remarked he and Yui had a lot of snark to snark battles. He wasn't one in Blood Covered, but that's justified.
- Declaration of Protection: Towards Yuka, naturally. Failing this can push him over the Despair Event Horizon.
- Driven to Suicide: In Corpse Party: Musume, Yuka dies and he kills himself to be with her.
- Half the Man He Used to Be: In the end of the OVA, not even half.
- The Hero: Although in Blood Covered his chapter is in the middle of the game; every chapter before his has the characters fall deeper and deeper in trouble. When he first appears, he acts like a badass and his appearance is when the characters start to find a way to get out of there. Also the other characters treat him like the leader.
- Heroic BSOD: If Yuka or Naomi die.
- Heroic Sacrifice: He willingly gave Naomi his scrap in the OVA, not knowing what would happen to him if he used a scrap from another group.
- Heterosexual Life-Partners: He and Yoshiki seem to be this.
- Hyper Awareness: Displays quite a bit of this in Blood Drive when he sees Yoshiki geared up to go to Heavenly Host under the guise of going hiking. By gauging his reactions when he mentions Heavenly Host, Ayumi and the paper charm on his backpack, he figures out Yoshiki's true intentions. Yoshiki even refers to it as Satoshi's primal instincts.
- In Blood Covered, when he finds a toilet for Yuka, he asks which one she's going for, so he can measure the amount of time she takes before he figures out something is wrong.
- Idiot Ball: In the anime OVA, he leaves Yuka to do her business, and lets Sachiko, a ghost girl among ghost children who are known to slaughter everyone, go along with her. If this isn't bad enough, he goes inside and tells her to "scream if she needs anything". Guess three times if this happens.
- Nice Guy: One of the nicest characters in the whole game. No wonder the ladies love him.
- No Hero to His Valet: He is thought of as the leader of the group, the only one to challenge this is Naomi. Who he probably has known the longest, excluding his sister.
- Oblivious to Love: And, well, you can't really blame the guy: Naomi is such an extreme Tsundere that she practically comes off as emotionally abusive towards him, so it'd make sense that he wouldn't be able to see that she's in love with him. He does have a Love Epiphany with regards to Naomi in one ending. It's not in the True End, though.
- Standardized Leader: He can come across as very bland in contrast to the rest of the cast since he is so stable and normal as a borderline everyman.
- Why Did It Have to Be Snakes?: He isn't a fan of Horror Stories, so of course he ended up with a Class Rep who adores telling them, exposing his phobias for all to see and mock. Then they end up being dragged into one...
- You Are Worth Hell: Towards Naomi, if she loses her piece of the charm, he says he would stay with her. As well as in Book of Shadows, when he is put in a time loop. Instead of leaving when they refuse to listen to him, he decides to do the charm again, as he is the only one who can save everyone.
- Voiced by: Rina Sato
- Alliterative Name: Naomi Nakashima.
- All Love Is Unrequited: Satoshi is as much in love with her as she is with him, but he doesn't realize his feelings in most of the endings because he's afraid of being ridiculed by Naomi because of her extreme Tsundere attitude.
- Brainwashed and Crazy: She gets possessed by the darkness in Heavenly Host Elementary and ends up killing Seiko while under its influence. This can trigger a Despair Event Horizon in one of the Wrong Ends.
- Cassandra Truth: In Book of Shadows, her mother doesn't believe anything she says about Seiko, since her existence was erased upon her death in Tenjin.
- Cannot Spit It Out: Not only her feelings for Satoshi, but also the guilt she feels immediately after lashing out at Seiko. If she tries to apologize, she's hardly even able to get the words out, and neither she nor Seiko feel any better. In Book of Shadows, she actually has a coughing fit.
- Dead All Along: As revealed in the last chapter of Corpse Party: Musume.
- Despair Event Horizon: In Chapter 5. Your choices determine what happens to her: either a message from Seiko will eventually convince her that Seiko doesn't hate her and she rejoins the group, or she goes crazy and charges at the group while dragging Seiko's body behind her.
- Disappeared Dad: Only her mom is made clear to be in her life.
- Death by Adaptation: In Corpse Party: Musume. She ends up becoming Sachiko's replacement.
- Driven to Suicide: Eventually, the horrors of the school push her past the breaking point and she tries to hang herself. Talking her down is necessary for that chapter's True End.
- Eye Scream: One of her eyes is cursed in Blood Drive, giving her excrutiating pain but also granting her the ability to see spirits.
- Fatal Flaw: Not only is she unable to bring herself to confess her feelings, she tends to take out her frustration verbally on everyone around her. Even when she knows it won't help anything, she can't stop herself...
- Hartman Hips: And Seiko will constantly remind Naomi of those.
- Heroic Sacrifice: In the PC-98 version, she may do this in order to save Yuka. Sadly, this locks you into an ending that makes this a Senseless Sacrifice.
- Honor Before Reason: Why she tried to revive everyone in Book of Shadows.
- Hidden Depths: In-universe example in the PC-98 version. Everyone present is surprised Naomi can play the piano and is apparently very good at it. That doesn't get any other mention in any subsequent games, however.
- Informed Attribute: The Corpse Party Blood Covered's character guide gives Naomi the characteristics of being Satoshi's Lancer, but she spends too much time crying over Seiko to fill out this role. The role of the Lancer goes to Ayumi who doubles as The Smart Girl.
- Maybe Ever After: The True Ending in PC-98, where she has some alone time with Satoshi in their classroom and she invites him to come over to her place and see her play the piano.
- My Greatest Failure: She feels that if she hadn't taken out all her frustrations on Seiko, they wouldn't have separated and Seiko wouldn't have died. She tries to rectify this after being given the chance to do so in Book of Shadows. She succeeds, but Seiko freaks out (as it turns out, Naomi was Brainwashed and Crazy and tried to kill her) and runs away from her, headlong into a Death Trap. At this point, Naomi is forced to accept that saving Seiko at all is impossible.
- Never Got to Say Goodbye: Naomi splits up with Seiko shortly after the two get into an argument. The next time she sees Seiko, she's hanging by the neck in a bathroom stall. Considering it was Naomi's fault they split up in the first place, she feels pretty bad about it. She later finds out that she was the one who did that to her, albeit whilst possessed.
- Patient Childhood Love Interest: Sorta. She's known Satoshi since seventh grade.
- Screw Destiny: Her attitude in Book of Shadows, both in the "World Loop" chapters and the chapter following Blood Covered's True Ending. By the end of "Engraved Seal", this becomes You Can't Fight Fate.
- Thousand-Yard Stare: In the beginning of Book Of Shadows, and end of the Tortured Soul OVA.
- Tsundere: A typical tsun-tsun; this is Deconstructed, as it feeds into her Fatal Flaw.
- Twisted Ankle: Suffers from one after a bad landing, making it hard for her to get around at first.
- Unlucky Childhood Friend: Her Fatal Flaw is a heavy driving force here towards Satoshi.
Voiced by: Asami ImaiThe Class Rep for 2-9, Ayumi is bright, cheerful, and absolutely loves scary stuff. Creepy stories, strange rituals... she loves them all, and can't resist taking advantage of her position to draw her classmates into her games. Especially Satoshi, since he's so funny when he's freaked out...!
- Axe Crazy: In the Wrong Ends where she is possessed and you don't snap her out of it. She might shove Yoshiki down the stairs so hard his skull cracks, stab Satoshi with a pair of scissors, beat Naomi to death with her bare hands...
- In the Corpse Party: Musume manga, towards the end, she really loses it. She first brings up the subject of murder and black magic to Yoshiki as they're walking home. When Yoshiki tells her that killing anyone for any reason is wrong, she snaps at him and starts calling him out. Once he brings her home to calm down, it only gets worse. He leaves her alone for one minute to come back to find her using a pen to injury herself, and then stabs herself in front of Yoshiki repeatedly with an insane look; tearing up her arm with a pair of scissors.
- Big "NO!": At the end of Book of Shadows, her sister gets her head chopped off right in front of her. Ayumi lets out a scream leading up to the ending credits of the game.
- Big Sister Instinct: To Yuki Kanno, and to a certain extent, the other children who were victims of the 1973 Tenjin Elementary kidnapping and murder case.
- Blood-Splattered Innocents: Book of Shadows ends with her drenched in her sister's blood after her head explodes whilst hugging her in the aftermath of a Big Damn Heroes moment.
- Break the Cutie: Her sister's death and the events of Heavenly Host do this to Ayumi.
- Brainwashed and Crazy: She gets possessed fairly often, and if you make the wrong choices, you end up with Wrong Ends where she kills one of the others.
- Child Hater: Inverted; she doesn't seem to trust adults too much, besides Yui.
- Class Representative: As said she is one for her class
- Cool Big Sis: Has two (Hinoe and Ms. Yui) and is one to Yuka and Yuki Kanno.
- Cute Witch: In Book Of Shadows, we learn she is descended from a family that really had magic powers. Her older sister is a Hot Witch instead.
- Damsel in Distress: So much, but by the prologue of Blood Drive, she gets better.
- Dark and Troubled Past: It looks she still hasn't gotten over it by Dead Patient, to the point where she has been shown to be in an Angst Coma.
- Death by Adaptation: In the novels, she becomes the new Sachiko of Heavenly Host.
- Demonic Possession/Grand Theft Me: Her latent psychic powers attract spirits to her, but because she hasn't learned to control them yet, she is easily subject to possession. In the prologue of Blood Drive, she gets a lot better.
- Dull Eyes of Unhappiness: Whenever she goes through Demonic Possession. Has this at the end of Blood Drive and in Dead Patient.
- Evil Laugh/Laughing Mad: If she's possessed or taken over by the darkening.
- Fatal Flaw: From Book of Shadows onwards, she tends to think first and foremost about whatever her mind is set on at the time, but doesn't quite plan ahead for the possible risks. In Book of Shadows, her attempt at reviving Mayu without proper research on how the Book of Shadows works not only give Mayu a severe case of Came Back Wrong, but also nearly gets her and Naomi killed, if not for Hinoe's interference...which causes her to be beheaded in front of Ayumi. Following that, in Blood Drive she is set on going back to Heavenly Host with the same goals as before, as well as intending to retrieve the Book of Shadows from there. Only she, again, doesn't have any sort of plan at all, which Yoshiki points out. She ends up disregarding Yoshiki's concerns and going to Heavenly Host with someone whose attitude is like a huge Obviously Evil neon sign flashing over his head.
- Fighting from the Inside: Whenever she has to overcome Demonic Possession or being Brainwashed by the darkening.
- Girlish Pigtails: In the manga, she's shown to have had this hairstyle since she was a little kid.
- Heroic Sacrifice: Sacrifices herself to the Book of Shadows, which restores everyone's knowledge of her deceased friends' existence in exchange for wiping out her own from her friends' memories.
- Honor Before Reason: Why she decides to go back to Tenjin Elementary in Blood Covered and why she tried to revive her friends in "Book of Shadows".
- The Lancer: Naomi's supposed to be The Lancer to Satoshi, but she's too broken for it to work, so Ayumi takes the role as well as doubling as The Smart Girl.
- The Load: She gets possessed quite a bit. Though in "Book Of Shadows", she does get better.
- Love Makes You Crazy/Love Makes You Evil: In a bad ending, Ayumi burns Naomi's paper scrap, then beats her to death. While covered in blood, she laughs and praises herself. Though Naomi does have the last laugh.
- In the Musume manga, Ayumi stabs Naomi's dead body again and again, then cuts it into pieces, pushes Yoshiki off a cliff, then attempts to kill Yuka. Though she was possessed by Sachiko the whole time. This even carries over in the PC 98 version.
- Many Spirits Inside of One: :In Book of Shadows, she is literally fought over by other vengeful spirits because they see her as their only hope.
- Morality Chain: Yoshiki is hers; he keeps her mental state in check, and helps to keep her from having anymore Freak Outs. If he's away from her for too long, it never ends well.
- Nightmare Fetishist: Subverted. As much as she loves horror stories, getting flung headfirst into one understandably freaks her right out.
- Oblivious to Love: At least in regards to Kishinuma's crush on her, she's Ichika-levels of dense. Most likely because of her crush on Satoshi.
- One Steve Limit: Averted: She's not the only Shinozaki in the game. They're distantly related through being descended from a lineage with strong psychic abilities.
- Protectorate: For Yoshiki as her dying often nets you a bad end.
- Rescue Romance: With Yoshiki, all the time.
- Ret Gone: At the end of Blood Drive, she sacrifices herself to the Book of Shadows and is erased from her friends' memories, in return for restoring the memories of Seiko, Mayu, Morishige, and Yui to the world.
- Saved by Canon: She makes an appearance in the prologue of Dead Patient, which is set after Blood Drive.
- Self-Harm: She does while having a Freak Out in Blood Drive.
- Also does this in Corpse Party: Musume where she uses a pen and scissors to tear up her body due to her surviving Heavenly Host while the others have either died or been put in danger.
- Single Woman Seeks Good Man: She likes Satoshi, as she feels she can trust him. Seems to slowly transition to Yoshiki as of Blood Drive.
- Slasher Smile: Shows these when possessed.
- The Smart Girl: She has the most knowledge of the occult so she fills out this role in the game.
- Thousand-Yard Stare: Sports one in her cameo appearance in Dead Patient.
- Tsundere: She seems to be one for Satoshi and Yoshiki. She is known to have a crush on Satoshi and generally she scares him, while when she's with Yoshiki, she is very rude to him. But it is hinted she might like him at the end of Blood Covered and in Blood Drive.
- Took a Level in Badass: In Book of Shadows. Especially in the prologue to Blood Drive, where she manages to force away possessions by herself and even prepares and chants up a spell to revive the dead. In Blood Drive, she takes another level in badass once The Book of Shadows accepts her as its master.
- Ungrateful Bitch: Comes across as such towards Yoshiki. He spends most of his time saving her life and stopping her from going insane while she insults him any time they disagree on something. She becomes aware of his actions and eventually feels grateful for it in Blood Drive.
- Unwitting Instigator of Doom: Performing the Sachiko Ever After charm was her idea.
- Violently Protective Girlfriend: Acts like one to Satoshi, though if she is acting like this, you are probably on your way to a Wrong End.
- What the Hell, Hero?: The spirits of her dead friends appear to her in Blood Drive and tell her that while they are grateful that she wants to revive them, her attempts to do so are only getting more people killed.
- Yandere: At the very least, she starts showing signs of Sanity Slippage in one bad ending. She actually burns Naomi's Sachiko charm (which she needs to get home), then kills her in a particularly horrific Wrong End. Naomi has the last laugh, though.
Voiced by: Yuuichi NakamuraDespite having the Face of a Thug, Yoshiki is actually a pretty nice guy. Likes teasing Satoshi, but that's the norm among his classmates, anyway. After they're pulled into Tenjin, he vows to protect Ayumi at any cost.
- Action Survivor: He's the most capable in Heavenly Host and survives with the most injuries.
- All Love Is Unrequited: Though he cares for Ayumi, he thinks she's more interested in Satoshi. She may return his feelings later on, though.
- All of the Other Reindeer: Before he started his second year, he admits he was a loner.
- Always Save the Girl: If he fails and Ayumi dies...it never ends well. He'll either get killed off later, or be Driven to Suicide because he can't live without her.
- Badass Normal: The biggest badass out of the main five and one of the biggest in general but doesn't even have the "perks" others like Ayumi have.
- Because You Were Nice to Me: Why he fell in love with Ayumi.
- Big Brother Instinct: Shown more in Book of Shadows where he loses Ayumi again, and on his way to find her, he stumbles across Mayu and Nana. For a little bit, he has to save and protect them until he finds Ayumi. Book of Shadows hints that he would probably be this way towards his own little sister, Miki.
- Big Damn Heroes: Saves Yuka from Kizami in Tortured Souls, but unfortunately she was already fatally injured.
- Changed My Mind, Kid: Ayumi and Yoshiki are returned to their classroom by Yuki. Ayumi wants to return to save Satoshi and the others. If Yuka was was caught by Kizami (or if you choose to not to), Yoshiki refuses to go back. Naturally, he ends up going back anyway. It still leads to a Wrong End, though.
- Same case in Tortured Souls. He comes back in time to save Yuka, and is then killed trying to hold off Yoshikazu so that Ayumi can get Yuka to safety.
- The Big Guy: He's the toughest out of all of the kids and he takes the most risks as well. He can also be considered Ayumi's personal Lancer as well.
- Chick Magnet: Played for Laughs in one of the drama CDs, where Yoshiki gets confessions from Naomi, Yui, and Yuka. Later on, even Satoshi, Yuuya, and Morishige confess their love to him. This ends up being a hallucination Yoshiki is having while being buried alive.
- Cooldown Hug: Gives one to Ayumi when she is possessed.
- Crazy Jealous Guy: He's really good at hiding it, and doesn't act on it until he finally snaps at Ayumi about her feelings to Satoshi later.
- Death by Adaptation: In Tortured Souls.
- Deadpan Snarker: Has his moments.
- Delinquent: Most people think he's one, due to his dyed hair and his lack of interest in school. But he did used to skip a lot and smoke.
- Devoted to You: He would do anything for Ayumi, and she doesn't even realize it.
- Driven to Suicide: In the original PC-98 game, he becomes suicidal if Ayumi dies. In one ending, he tries to attack Satoshi before breaking down in tears and dropping the knife; in another ending he simply disappears, and Satoshi wonders if the guilt of leaving Ayumi behind was too much for him.
- Even the Guys Want Him: It was in a fake dream when Yoshiki was being buried alive, though...
- Face of a Thug: He may look like your typical Delinquent, which he used to be to an extent, but he's a Nice Guy and will look out for his friends.
- Heartbroken Badass: Anytime if Ayumi dies.
- Heroic Sacrifice: In the OVA, he blocks the door so Yoshikazu can't get to Ayumi and a wounded Yuka. Yoshikazu just plows through.
- Heterosexual Life-Partners: He and Satoshi seem to be this.
- I Choose to Stay: At the end of Blood Drive, he chose to stay with Ayumi when she absorbed the power of the Book of Shadows, and was erased from the others' memories along with her.
- Informed Flaw: In his character description it states that he is prone to outbursts when frightened or upset and is essentially a Jerk with a Heart of Gold character. In the actual game he rivals Satoshi for being the kindest and the most level-headed.
- Jerk with a Heart of Gold: He's this in the intro, but for the rest of the game he slides into the Nice Guy.
- Knight in Shining Armor: He wants to be seen in Ayumi's eyes as this, regardless that he already is one.
- Even Azusa calls/thinks of him as this, she even points out that the kanji is in his name. Kinda.
- Living Emotional Crutch: Ayumi is this for him. He loses the will to live if she dies.
- Love Martyr: This guy is willing to put himself through hell and back for Ayumi, he does reach his limit at one point when he's had enough of Ayumi's constant concern for Satoshi in Blood Covered.
- Nerves of Steel: Intimidates spirits that are possessing Ayumi out of her body while they're trying to hurt him.
- Parental Abandonment: He lives away from his parents and is reported to have a bad relationship with them.
- Power Trio: With Mayu and Nana in Book of Shadows for a little bit.
- Ret Gone: In Blood Drive, he decides to stay with Ayumi during her Heroic Sacrifice, and is wiped from his friends' memories along with her.
- Senseless Sacrifice: In the PC-98 game, he can sacrifice himself to save Ayumi's life. Ayumi escapes the school, but ends up dying the next day anyway.
- Single Woman Seeks Good Man: Inverted, he gained his feelings for Ayumi when she got him out of trouble and encouraged him to graduate high school.
- Undying Loyalty: To Ayumi, and only if she'd be able to see it.
- Voiced by: Eri Kitamura
- Big Brother Worship: She adores Satoshi. And not just as a sibling.
- Cruel and Unusual Death: In the anime OVA, she's officially killed off by Kizami.
- Also in her chapter in Book of Shadows, which shows what happens to you if Kizami catches you in the original game: no matter what choices you make, you end up getting killed by either Sachiko or Yoshikazu.
- Damsel in Distress: A particularly strong trouble magnet in the original PC-98 game.
- In Blood Drive, she is kidnapped by Misuto.
- Death by Adaptation: In the Tortured Souls OVA and in Corpse Party: Musume.
- Demonic Possession: Possessed by Sachi in Blood Drive.
- Heroic Sacrifice: In Chapter 5's Extra Ending, where she Takes The Scissors for Satoshi.
- Huge Guy, Tiny Girl: Has this dynamic with Kizami, who is a good 46 cm taller than her.
- The Load: Forces Satoshi (and by extension, the player) into an epic quest for a usable bathroom when they could have focused on trying to find his classmates and teacher. Also the most useless of the nine characters.
- Older Than They Look: Though she's only a few years younger than the rest of the cast, the age difference seems particularly pronounced thanks to her uniform and immaturity. She also acts much younger than she is, thanks to being spoiled rotten by her parents.
- Out of Focus: In the first half of Blood Drive, due to Satoshi wanting to keep her out of the action. The Big Bad ends up luring her to Heavenly Host and kidnapping her for use in his plans.
- Potty Emergency: Happens to her. Unfortunately, the lack of working bathrooms doesn't do her any good. Eventually leads to a Potty Failure, courtesy of Kizami.
- Protectorate: To her brother and to Yuuya Kizami. Too bad Kizami's a murderous nutcase.
- Spoiled Brat: It's likely due to fear and stress, but she has this attitude quite a bit while trapped in the school.
- Spoiled Sweet: She may be spoiled, but nobody can deny she cares a lot about her brother when she gives him (or tries to, depending on Satoshi's choice) her caramel beads as a good luck charm.
First entered in Corpse Party: Blood Covered
- Voiced by: Satomi Arai
- Anguished Declaration of Love: In Book Of Shadows.
- Cat Smile: A common expression of hers, especially in the manga.
- Cruel and Unusual Death: Murdered by her Brainwashed and Crazy best friend. Horrifying and heartbreaking, to say the least.
- Genki Girl: A very energetic and seemingly positive girl.
- I Want My Beloved to Be Happy: Although she has feelings for Naomi, she acts as a Shipper on Deck for her and Satoshi.
- Lovable Sex Maniac: She took any chance to gaze and feel up Naomi. It never got to a rapey feeling, though.
- Missing Mom: Her mom is gone so she has to pick up the slack at home.
- The Pollyanna: Even in death!
- Promotion to Parent: Her mother disappeared some time ago; since then, Seiko has grown into a surrogate mother for her siblings.
- Schoolgirl Lesbian: She has a very close friendship with Naomi, and they both love each other very much. However, Seiko's love for Naomi, is that of romantic.
- Stepford Smiler: She puts up a good front, but the truth is she's actually hiding a lot of sadness from her mother's disappearance. The same applies to getting stuck in Tenjin Elementary, where she acts cheerful to hide how scared she really is. This bites her in the ass hard when Naomi calls her creepy, saying that it in their situation it's pretty much impossible to be that cheerful.
- Undying Loyalty: As literal as it gets. She actually saves Naomi from herself from the other side of the veil of death. Even after NAOMI HERSELF was the one that killed her (sure, she was Brainwashed and Crazy at the time, but still).
- Voiced by: Yuka Nanri
- Friend to All Children: ...too bad the children weren't friendly to her.
- Hair Decorations: Catches up part of her hair in a small side ponytail.
- Like Brother and Sister: With Sakutaro. In Book of Shadows, it's implied that her feelings are more than that.
- Living Emotional Crutch: She is this to Sakutarou.
- New Transfer Student: Inverted; she was transferring out of Kisaragi, and the story starts on what was meant to be her last day there...
- Renaissance Man: Gender flipped. Jokes about being such with regards to her talents in the drama club: She acts, writes scripts, produces, and even makes costumes.
- Retirony: If only she'd transferred out sooner...
- To be fair, they performed the ritual in the first place because she was leaving, as the Sachiko Ever After Charm is said to be a friendship ritual.
- Voiced by: Tetsuya Kakihara
- Big Brother Instinct: Referenced in his spotlight chapter in Book of Shadows, where he muses darkly about how, while he's not particularly attracted to Yuka, seeing her scared and helpless was really exciting for him.
- Blind Without 'Em: As revealed in Extra Chapter 9.
- Creepy Monotone: In Blood Drive.
- Despair Event Horizon: When he finds out that the corpse he was most admiring throughout the course of the game was Mayu, he snaps. HARD.
- Did You Just Punch Out Cthulhu?: In 2U, when he's coaching her in acting skills, Sachiko's constant mess ups lead Morishige, on Serious Business mode, to slap her. And much to everyone's surprise, it actually fires her up to keep working hard to improve.
- Irony: Of the Dramatic sort. A key facet of his character is that he's completely unaware that the corpse picture he's most enthralled with and is using as an emotional crutch until he finds Mayu is Mayu.
- The Generic Guy: While the others are having their Establishing Character Moments in the classroom, he seems to be just... sort of there to establish that he exists and is Mayu's friend. His comes later.
- Go Mad from the Revelation: When he learns the corpse whose picture he's most obsessed with belongs to Mayu, he does ''not'' take it well.
- Last Name Basis: He doesn't like people calling him by his first name, so everyone calls him by his last name, save Mayu, who calls him "Shige-nii".
- Like Brother and Sister: It's never implied to be anything romantic between him and Mayu. In Book of Shadows, it's implied that Mayu has feelings for him, and in an extra chapter of Blood Drive, he confesses that he has feelings for her.
- Loners Are Freaks: He admits to being anti-social to everyone else but Mayu. And he quite the hobby but still a good person]].
- Serious Business: Put him in charge of a play, and he won't settle for less than perfect. He slaps SACHIKO when he's coaching her because she keeps messing up lines while he's on full-strict coach mode. And it WORKS.
- Voiced by: Miyuki Sawashiro
- Cool Big Sis: Has a close sisterly relationship with Ayumi Shinozaki, and Ayumi in returns thinks of her as another sister. Which makes her death much more brutal on Ayumi, especially when she dies right in front of Ayumi's eyes.
- Cool Teacher: She is very serious about her job and the safety of her students.
- Determinator: Let's see... She gets a cabinet dropped on her back, her entire back is pierced with knives, and she's being baited by a sadistic ghost who tries to get her to beg for her own life over that of her students'. What does she do? Plead for him to leave her students alone. After she manages to get the cabinet off of her, she starts to wander around, bloody and injured, all while trying to hold her shattered right arm in place. We finally see her again in chapter 5, when she meets up with Ayumi... But the reunion is short lived; the floor ends up being a trapdoor, and Yui ends up holding onto the edge (with both arms no less) so Ayumi can climb up and be saved. As we learn in the Extra End of chapter 4, this is what finally leads to her Heroic Sacrifice. Yui-sensei is awesome.
- Did Not Get The Guy: She had feelings for Tsukasa Mikuni, her friend in high school, that continued to today. Any chance she may have once had is gone, as she died and all memory of her is gone.
- Dojikko: When not being a teacher, she is very clumsy. Although she was having a fever and cold when she showed said trait, so it may have been a side effect.
- Shipper on Deck: She ships Ayumi/Yoshiki, as Yoshiki reminds her of her high school crush.
Others appearing in Blood Covered
Naho SaenokiA high school student with great psychic potential. She blogs about curses, and is lodging with Kibiki due to circumstances at home.
- Berserk Button: Does not like when people ask personal questions.
- Cute Ghost Girl
- Dead All Along: At least she's honest about it. Most likely, she's retained her sense of self because of her psychic abilities.
- Despair Event Horizon: She crossed it twice. The first one comes from Book of Shadows when she, after deciding to put the kibosh on the investigation realizing it's too dangerous to go on with it, comes home to tell Kibiki about it only to find out she was too late and that Kibiki had already gone on without her, and the second one when she finds out she succumbed to the darknening and killed Kibiki.
- Dull Eyes of Unhappiness: Often described as having eyes 'like a dead fish'.
- Freak Out: When Ayumi reveals that she killed Kibiki. Complete with Bad Black Barf
- Good Is Not Nice: In her spiritual form in Blood Covered.
- Hair Decorations: A star-shaped hairpin. Fitting for one who works with the occult.
- Romantic Two-Girl Friendship: With Sayaka. Until she goes insane.
- Start of Darkness/Sanity Slippage:: "Purgatory" shows that she was a really nice girl when still alive, had a heartwarming friendship with Sayaka, and wanted to avoid people being harmed by Sachiko. Her descent into madness started when she came home after her guest appearance at Sayaka's show was hijacked by Sachiko, with the resolve to put an end to the investigation on the Shinozaki Estate and Heavenly Host when the curse Sachiko placed on her became too dangerous...only to find Kibiki's note telling he went over to Heavenly Host without her. She screams and cries in absolute despair and can only resort to asking for Sayaka to perform the ritual with her so she can rescue Kibiki. She starts losing it afterwards. Between the time Sayaka returns home briefly to let her mother know she was going out and the time they pulled the ritual, Naho starts showing insanity traces that indicate Sachiko was influencing the Darkening within her when she posted the wrong info on her blog. The Darkening only got worse from there.
- Stoic Spectacles: After her death.
- Used to Be a Sweet Kid: Would you believe that before going to Heavenly Host, she used to be an absolutely cheerful girl who was prone to make cat noises complete with gestures?
- Well-Intentioned Extremist: Okay, maybe doing it all for your beloved mentor isn't that well-intentioned, but still. Although Book of Shadows indicates that she did so under the influence of The Darkening.
- Voiced by: Tomokazu Sugita
- Big Brother Instinct: Actually wants to find his own little sister. There's just one problem: He doesn't have a little sister.
- Big Brother Mentor: To Yuka after she is separated from her actual big brother. Subverted so damn hard.
- Coat Over the Shoulder: He keeps it even when he's forced into Kisaragi's uniform in 2U.
- Gratuitous English: Tells Yuka to "RUN, RABBIT, RUN" just before his death. If he catches you, he says "I'VE GOTCHU!"
- Huge Guy, Tiny Girl: Has this dynamic with Yuka.
- Voiced by: Tsubasa Yonaga
- Defiant to the End: He fights off Kizami so Yuka can run away, and rather than be in despair when faced with death, he just tries to talk Kizami out of his sociopathy.
- It's All My Fault: Somewhat blames himself for Kizami's sociopathic nature since, as his childhood friend, he didn't call him out on it sooner.
- Say My Name/Running Gag: Being pushed into pits, and screaming the name of whoever pushed him as he falls in the most dramatic, hammiest way possible. He does so when Kizami kicks him into a hole and when Mitsuki does so in a Wrong End in Corpse Party 2U.
Kou KibikiA writer of mystery novels researching what really happened in the 1973 kidnapping and murder case. He went to Heavenly Host to investigate it and how it connects to the 1973 kidnapping and murder case.
- Adaptation Expansion: The manga adaptation expands his role by actually have him appearing as a spirit to give valuable info to the main 5.
- All-Loving Hero: He didn't want Naho to go with him to the investigation because he didn't want to risk her being trapped in Heavenly Host. He also worried about other people getting trapped in it. Sadly, leaving her behind ended up in Naho causing both after she goes insane.
- Badass: He made some pretty idiotic decisions, such as leaving Naho behind and going to Heavenly Host on his own, when he doesn't have any spiritual powers like Naho has, before more info could be gathered about it, even if he had her well-being in mind. But still, to go over to Heavenly Host on his own volition takes balls of adamantium. He survived for quite a while as well. Until Naho was taken over by The Darkening and killed him.
- Idiot Ball: Even though he wasn't aware that he was biting off more than he could chew in regards to Heavenly Host's investigation, leaving Naho, AKA the girl with psychic powers when he has none, behind when going to Heavenly Host proved to be a bad move in the long run, even if he did it out of concern for her well-being. Even Naho thought it was stupid. It's like facing off Ganon without the Master Sword.
- Multicolored Hair: Has a dark blue strand on his black hair.
- Sexy Mentor: He fills the part quite well. Naho certainly agrees!
- Unwitting Instigator of Doom: Leaving Naho behind was the cause of her Start of Darkness. Ultimately, it led to his demise and the demise of a good deal of students.
Shougo TaguchiA cameraman helping Kibiki with his case.
- Butt Monkey: Is there a time when Naho isn't putting this guy down?
- Camera Fiend: A video camera at least.
- Eyes Always Shut: Even when he's having the Freak Out mentioned below, his eyes doesn't seem to open.

- Motor Mouth: Morishige views him as such.
- Nice Hat
- Too Kinky to Torture: He actually enjoys being Naho's Butt Monkey.
Masato FukuroiThe chairman of the student council at Byakudan High School.
- Benevolent Boss: He has a stiff and serious personality, but is also surprisingly caring, and forgiving of Ryosuke and Tomohiro loafing around.
- Brainy Brunette
- Covert Pervert: One Extra Chapter focusing on the Byakudan Students has him getting hooked with an H-Game and in Corpse Party 2U, he joins Kurosaki in his efforts to stall Sachiko as much as possible so they can continue to enjoy seeing Mitsuki being groped by the tentacles Sachiko sent on them to punish Kurosaki for insulting her. Mind you, Fukuroi is doing so when he is being ''crushed by tentacles himself''.
- Voiced by: Haruka Tomatsu
- Cool Big Sis: In presence, she gives off this vibe to her class and the student council.
- Freak Out: Satoshi and Yuka find her in the midst of one. Despite trying to speak to her, she's... not very receptive. The next time you see her, she's dead.
- The Dreaded: A more comedic example. She was this back at her own school, to the point of having the nickname "Hellgirl Mitsuki".
Emi UrabeA student who attends Byakudan High School, and Mitsuki's friend since their first year. She likes fortune telling, and was the one who suggested the friendship ritual to the others at Byakudan.
- Get A Hold Of Yourself Man: Tries to do this to Ohkawa to snap him out of his belief that Katayama is alive, unsucessfully. She is understandably freaking out because Sachiko was drawing near.
- Freak Out: During all her appearances in Book of Shadows.
- Killed Offscreen: Found dead from being struck with a sledgehammer to the back of the head in both Book of Shadows and the PSP version of Blood Covered.
- Plucky Girl
- Scary Shiny Glasses: In one Wrong End in 2U where She eats and kills Naomi.
- All Girls Want Bad Boys: Averted. She dislikes Shimada for his flighty relationship with girls and prefers the "cool and spotless" Kizami. The poor girl has no idea.
- Driven to Suicide: Satoshi can find her after she gets Killed Offscreen. According to the name tag on her corpse, she cut out her own tongue.
- Freak Out: Satoshi finds her in the middle of one in Chapter 4 if he fails to save Naomi, and she ends up trying to kill him.
- Plucky Girl: She remains optmistic despite how dire things seem for her and her schoolmates. When she sees Kizami's true colors, she starts losing it.
- Spell My Name with an "S": The official English translation spells her name as "Tohko".
Nana OgasawaraA seventh grader at Musashigawa Girls' Junior High. Her story is told in the Extra Chapter 1, where she agrees to help a ghost find the items that were taken from him.
- Hair Decorations
- Plucky Girl: After Mayu and Yoshiki find her in Book of Shadows, she maintains a positive attitude throughout the whole chapter. Until she's taken by Yoshikazu.
- She's Got Legs: According to Mayu.
Chihaya YamaseA seventh grader and classmate at the same school as Nana.
- Fragile Flower
- The Load: Viewed as such by Nari.
- Shrinking Violet
- Spoiled Sweet: She was so used to people's handholding towards her that during her first moments in Heavenly Host, she instinctively expects people to tend to her whenever she needs it, which Nari calls her out on. But she's not a bad person by any definition of the world.
Nari AmatoyaA seventh grader at the same school as Nana. Although she and Nana are in different classes, they are old friends.
First entered in Corpse Party: Musume
Miyu ShinoharaExclusive to the manga series, Miyu was with the First Five listening to Ayumi's horror stories and got sucked into Tenjin together with them, though he and Yuka were separated from the group in the process.
- Bury Your Gays: He's the first one to go, and he didn't last for the first book.
- Combat Tentacles: He was a victim of one.
- Even the Guys Want Him: Attributed to his adorable schoolgirl looks.
- Off with His Head!: Standard fatal fate.
- Passionate Sports Girl: Only that he looks like a girl. According to an omake, not all the boys are aware of who he really is. At most, only a few notice a bulge coming from his bloomers, but another passed it off. Other than that, he likes sports and reliably ace in them.
- Wholesome Crossdresser: He can be a convincing schoolgirl.
- You Go Girl: According to an omake, he was cheered by the guys as such while they're unaware of his true sex.
The new victims of Corpse Party: Book of Shadows
- Voiced by: MAKO
- Advertised Extra: For some reason, the game icon for Book of Shadows has her standing in front of Heavenly Host, despite her limited appearance.
- Beauty Mark: A small one in the left side of her mouth.
- Nice Guy: Well girl. She even agrees to enter Heavenly Host with Naho to rescue Kibiki and Taguchi.
- Romantic Two-Girl Friendship: With Naho.
- Schoolgirl Lesbian: Corpse Party 2U pretty much cements her as this, with the amount of Ship Tease and Les Yay vibes she has with Naho, outright nosebleeding when she finds herself on top of Naho, fawning over Naho, engaging into Skinship Grope towards Aiko and later Naomi. She's pretty much Paulownia High School's version of Seiko.
- Undying Loyalty: To Naho, to the point of agreeing to go to Heavenly Host with her with no hesitation, and refusing the chance to escape Heavenly Host's loop because it would mean leaving Naho behind.
- Voiced by: Nobuhiko Okamoto
- Covert Pervert: Has a thing for Student-Teacher Romance
- Determinator: Nothing seems to faze this guy. Not even Yoshie.
- The Lady's Favor: Gender-inverted: He lends Yui the pencil he used for his high school entrance exams for good luck during her college entrance exams. He tells her that he's not letting her keep it. He needs it for his exams, too.
- Understanding Boyfriend: He is very much this to Yui, even though they weren't dating during his canon appearances.
Kai ShimadaA student who attends Byakudan High School, and who has a one-sided rivalry with Kizami.
- Bishōnen: Models for a men's magazine.
- Bullying a Dragon: He pulls a knife on Kizami to intimidate him. It ends as well as you'd expect.
- The Casanova: Supposedly has 10 girlfriends. Seemingly all at the same time.
- Establishing Character Moment: When the entrance door is open and they're presented with a chance to escape, Kai doesn't hesitate to leave everyone behind, thinking solely of his survival. Then, to twist the knife in, he makes a shallow attempt to charm Touko into ditching her friends and come with him.
- Fiery Redhead: Very impulse driven, hot headed, headstrong, and arrogant. And yes a redhead, be it natural or dyed.
- Jerk Ass: Touko regards him as "the slimeball to end all slimeballs". He earned that opinion with gusto.
- Handsome Lech: According to Touko, he has 10 girlfriends.
- Hot Guys Are Bastards: Very much so. Not to the extent of Kizami, but still...
- Screw This, I'm Outta Here!: When they open the entrance door of Heavenly Host, he is very quick to run away from there.
- Small Name, Big Ego: 3 letters, VERY full of himself.
- Unknown Rival: To Kizami, who outclasses him in just about every way. Especially in terms of sadism or as a threat.
Ryousuke KatayamaA student who attends Byakudan High School. He enjoys video games and is good friends with Ohkawa. We first meet him in Extra Chapter 4 of Blood Covered, but it isn't until Book of Shadows that we see him in the main game.
- Those Two Guys: With Ohkawa.
- Unwitting Instigator of Doom: He loses his leg in a trap and bleeds to death. His death causes Ohkawa to go nuts. After Kizami pushes his body down the stairs in an attempt to prove that he's dead, Ohkawa panics even more, calling Kizami a murderer. This causes Kizami to have his "epiphany": It doesn't matter whether the school kills you or he does.
Tomohiro OhkawaA student who attends Byakudan High School. He likes cute things and video games. We first meet him in Extra Chapter 4 of Blood Covered, but it isn't until Book of Shadows that we see him in the main game.
- Freak Out: He doesn't take Katayama's death very well. He insists that he's still alive and needs to get to the hospital. Kizami attempts to "help" him see the truth by pushing Katayama's body down the stairs to prove he's dead. This only freaks Ohkawa out more.
- Nice Job Breaking It, Hero: In a way. Kizami isn't exactly sane, but his "Whether you're killed by the ghosts or killed by me... makes no difference" epihpany was caused by Ohkawa calling him a murderer during his Freak Out.
- Those Two Guys: With Katayama.
Other (spoilers) Warning all spoiler tropes will be unmarked
Yuki KannoA victim of the 1973 Tenjin Elementary kidnapping and murder case, she appears as a ghost with her left eye missing.
- Advertised Extra: In Blood Drive, she is seen in the intro and one of trailers, but has no real role in the game. See Chuck Cunningham Syndrome.
- Brainwashed and Crazy: Thanks to the darkening. She temporarily gets better when she's appeased.
- Chuck Cunningham Syndrome: Makes no actual appearances in Blood Drive. Her only appearance in Blood Drive was really just Sachi in disguise.
- Creepy Child: At first.
- Cute Ghost Girl: When her tongue is returned to her.
- Exposition Beam: Once Ayumi and Yoshiki give her and the other two their respective body parts back, she sends them back to the classroom. Once there, she shows Ayumi the truth about how she and the others were murdered. Unfortunately for Ayumi, it's through Yuki's eyes.
- Face-Heel Turn: Once you appease Sachiko, the school chooses her as a replacement.
- Not Evil, Just Misunderstood: While initially extremely dangerous, she isn't really doing evil acts willingly; she's been corrupted by her violent death and by the school itself. She becomes very helpful to the heroes once she's appeased.
- Parting Words Regret: Though we never learn any details, the last words she exchanged with her mother were a huge argument.
- The Unintelligible: Because her tongue is missing. Once she gets her tongue back, you can understand her.
Tokiko TsujiA victim of the 1973 Tenjin Elementary kidnapping and murder case, she appears as a ghost with the top of her head missing.
- Body Horror: Ryou and Yuki only lost their tongues, and Yuki lost one of her eyes as well. Poor Tokiko lost her tongue and the top half of her head. And they show it in detail if she catches you.
- Brainwashed and Crazy: Thanks to the darkening. She temporarily gets better when she's appeased.
Ryou YoshizawaA victim of the 1973 Tenjin Elementary kidnapping and murder case, he appears as a ghost with his tongue missing.

- The Unintelligible: Because his tongue is missing. Once he gets his tongue back, you can understand him again.
The girl in red/Sachiko Shinozaki
- Voiced by: Ikue Otani
- Affably Evil: In 2U. Her resentment and hatred are lifted for 24 hours when its her birthday. She goes from the game's greatest horror to a surprisingly friendly ghost who likes to torment her victims in non-fatal ways just for shits and giggles. But she gets back to her usual Ax-Crazy self when the 24 hours is over, and forgets everything she experienced in her birthday.
- The Atoner: In Blood Drive.
- Bitch in Sheep's Clothing: Sometimes she likes to play the ally, or act like a helpless child, before turning around and killing people. In one bad end, she pretended to be Mitsuki by wearing her face as a mask, and briefly flirted with Morishige before revealing herself. Just to mix things up.
- Creepy Child: She died when she was very young, so her spirit has the appearance of a pale, blood-covered child.
- Cute and Psycho: 2U puts emphasis on the "cute" aspect. She's surprisingly adorable on her birthday, if only being Affably Evil at best.
- Deader Than Dead: See Heroic Sacrifice.
- Enfant Terrible: She died as a child, but became a malevolent spirit.
- Heel-Face Turn: In Blood Drive, since she has been appeased. She becomes a close ally to Ayumi.
- Hereditary Curse: The women in her bloodline are cursed with powerful black magic.
- Heroic Sacrifice/Redemption Equals Death: Uses up all her energy to turn back time so that Ayumi can have another chance to save her friends.
- Large Ham: Taken up to eleven in Book of Shadows.
- Morality Pet: Subverted. Both Blood Covered and Book of Shadows imply that on some level she genuinely likes Yuka, and she actually saves Yuka from Kizami in Blood Covered's True Ending path. But Sachiko's too Ax-Crazy for this to actually protect Yuka — in the Mire chapter from Book of Shadows, it's revealed that it was actually Sachiko who killed Yuka after Kizami catches her in that Bad End of the original game.
- Sealed Evil in a Can: In Blood Drive we find out that the dimension where Heavenly Host is something called a Nehan, where the dead can wander and interact with the living freely. Sachiko's mother created it using the Book of Shadows in order to be reunited with her deceased husband, but the spell failed and it rebounded on Sachiko, who wound up absorbing the entire Nehan into her body. When she was murdered, the seal was broken and the Nehan was unleashed, creating the alternate Heavenly Host.
- Slasher Smile: Her spirit often bears one when it isn't frowning or is just staring blankly.
- Stringy-Haired Ghost Girl: A pretty typical Ongyo spirit aside from being a child in red instead of a woman in white.
- Tongue Trauma: Has been on the giving and receiving end of this.
- Troubling Unchildlike Behavior: The spirits of children generally do not seek to murder the innocent.
- Undead Child: Her appearance is rather zombie-like.
- Used to Be a Sweet Kid: Before being killed blinded her with bloodlust and anger, she was a genuinely sweet child. Blood Drive reveals that it was not being murdered alone that distorted her character, but a curse that had been laying dormant within her since her mother's clandestine attempt at bringing back her dead father.
- Wounded Gazelle Gambit: Pulls this in Book Of Shadows, in one of the Wrong Ends and in Chapter 6.
- Yandere: At least at first. Sachiko started off killing so that her mother would have company, but after a while she began to enjoy it too much. After a while, Sachiko was just too far gone to stop. Yoshie's diary notes that Sachiko probably didn't even remember her own mother.
Yoshikazu YanagihoriA teacher at Tenjin Elementary, and the son of the headmaster. He was arrested for the kidnapping and murder of the three victims in 1973 but was actually being manipulated by Sachiko.
- Always a Bigger Fish: He's found crucified and impaled in Chapter 2 of Blood Drive, which pretty much establishes that there is a MUCH bigger threat this time around.
- Cool Teacher: Used to be one until his mental illness struck. An entry in Yoshie Shinozaki's diary suggests that she might have had something to do with the mental illness.
- Despair Event Horizon: Being controlled by Sachiko into kidnapping the three children and then witnessing her kill them in cold blood completely breaks him and leads to him being...
- The Dragon: An unwilling one to Sachiko, as she used his body to kill children.
- Driven to Suicide: He killed himself by hanging himself.
- Drop the Hammer: His zombie occasionally appears with a giant mallet. God help you if he catches you.
- Friend to All Children: What he was prior to kidnappings. In Chapter 6 of Book Of Shadows, he shows a lot of reluctance to kill Yuka despite Sachiko's orders. Teenagers are fair game, though.
- Insanity Defense: How he avoided going to jail. He actually was pretty insane at that point, so a mental hospital was probably the best place for him. However, he ended up escaping, broke into the school, and hung himself in the basement.
- Man Child: At the time of the incident, a disease had apparently caused him to regress to a childlike mental state, to the point where he couldn't even convey his thoughts. People noted that he was still a rather kind person even when he reached that point, so it was almost hard to believe that he'd commit such horrific murders. Which makes sense, seeing as he didn't commit the murders.
- Sins of Our Fathers: Yoshikazu's mental illness and regression are heavily implied to be caused by being cursed by Yoshie, Sachiko's mother. When you find her diary in-game, Yoshie mentions her hatred for Principal Yanagihori is so great, she cursed him and everyone in his bloodline. This basically means he's the very first innocent victim of Yoshie's and Sachiko's rage: even before the murder of the three children, Yoshikazu was already a powerless puppet under Sachiko's thrall.
Yoshie ShinozakiSachiko's mother, she was a doctor and a health official for Tenjin Elementary. She died after falling from a stairway landing in the school. She was the other victim of the incident in 1953. After she escaped being raped by the principal, he accidentally caused her death whilst chasing after her in an attempt to keep her quiet. Her death was subsequently covered up as an accident.She appears in-game as the ghost in the infirmary.
- Greater Scope Villain: The final chapter of Book of Shadows shows that she may have been the one who created the supernatural version of Heavenly Host in the first place, using a ritual from the Book of Shadows, a powerful grimoire passed down in the Shinozaki family. It is also hinted at that her magic may have been involved in Sachiko's death. And she was the one who created or at least discovered the ritual that would become the Sachiko Ever After charm eventually... Prior to their demise. The events of Blood Drive reveal that she accidentally set the pieces in place for the creation of the hell known as Heavenly Host in a misguided attempt to be reunited with her deceased husband.
- Hello, Nurse!: She was the school nurse.
- Hereditary Curse: Powerful black magic runs through her bloodline, and its passed from mother to daughter. Every man who marries into the bloodline is doomed to die because of this. She loved her husband enough to resort to the forbidden black magical secrets they'd passed down, and tried to escape to a dimension where she could be with his spirit. The spell failed, it rebounded onto Sachiko, and it spawned the hellish version of Heavenly Host after they were brutally murdered.
- Nice Job Breaking It, Hero: She tries to be reunited with the spirit of her dead husband out of genuine love. This act sets the pieces in place for the creation of Heavenly Host and results in countless deaths.
- Sins of Our Fathers: It's unknown what her ancestors did, but whatever it was left the women of her bloodline filled with immense black magical power.
Hinoe ShinozakiAyumi's older sister. She's obviously the one Ayumi inherited her love of the occult from.
- Big Damn Heroes: Saves Ayumi and Naomi from dying when their paper dolls are burning in Book of Shadows.
- Hot Witch: Grown up and has magic powers.
- Off with His Head!: She dies this way in Book of Shadows. Right in front of Ayumi, no less.
- Oneesama: Very soft-spoken and ladylike, and very encouraging of Ayumi.
- Adults Are Useless: Played with in Book of Shadows. She doesn't believe anything Naomi says about Seiko and thinks that Naomi has simply created an imaginary friend. However, this is justified as Seiko was erased from existence following her death in Tenjin, and Natsumi does try to get help for her daughter by speaking with a psychiatrist, doing the best she can with the information she has.
- Alliterative Name: Both starting with "Na" just like her daughter.
Haruna KizamiKizami's older sister.
- Hime Cut
- Cool Big Sis/Oneesama: Toyed with. Her profile indicates she enjoys flower arrangement, but she is rather harsh toward her younger brother. Because said brother has a tendency to torture animals.
Yuu ShinoharaOne of Seiko's younger brothers.
- Promotion to Parent: In Book of Shadows, we see he is this to his younger siblings. It is unclear if he was always this or if the retcon of Seiko made him this.
Kokuhaku AkaboshiA girl from Misato Municipal Brotherhood High that Satoshi and Yuka encounter in Chapter 3. Despite their attempts to communicate with her, she doesn't really respond. Her Name Tag is found in Chapter 5, indicating that she either died shortly after Satoshi and Yuka left or was already dead. Going back to the art room when controlling Kizami in Chapter 3 reveals that the Darkening took over her.
- Madness Mantra: Repeats one to try to keep the Darkening away.
- We Hardly Knew Ye: Her first appearance shows her constantly repeating a Madness Mantra, not even acknowledging Satoshi nor Yuka's presence. By the time you get back to where she was when playing as Kizami, she's already completely taken by the darknening, her body completely covered by the Darkening's shadow, moaning in pain. And unlike virtually all other students encountered or mentioned in the games, she doesn't get any role expanding.
Haruyuki InumaruA second year student at Paulowina Academy. He's a childhood friend of Sayaka, and fell in love with her. She harshly rejects him however, which he doesn't seem to mind.
- The Chew Toy: Boy, is he ever.
- Go Mad from the Revelation: When he learns Sayaka is dead...by finding her decomposing corpse.It hits him so hard he's taken over by the Superpowered Evil Side mentioned below.
- Hopeless Suitor: He takes all of Sayaka's harsh responses to his declarations of love as Sayaka being Tsundere, thinks they're destined to be together for being childhood friends, and doesn't seem to notice that she's actually a Schoolgirl Lesbian infatuated with Naho.
- Meaningful Name: Inu in Inumaru can mean dog. First he is a Dogged Nice Guy and then after his darkening he is stuck acting like a mad dog.
- Plucky Comic Relief: More evident in 2U, lessened in Blood Drive.
- Superpowered Evil Side: Due to his high spiritual energy, Inumaru's transformation is quite different when he succumbs to the Darkening. Instead of red eyes, he gets golden eyes and red symbols on his face. He also loses his humanity and starts acting like a dog with rabies and super strength.
- Too Kinky to Torture: Sayaka can give this guy a Megaton Punch but Inumaru will take it as gestures of affection, regardless of what Sayaka says.
Aiko NiwaAnother student from Paulowina Academy, with a knack for money and paranormal items, also possessing spiritual powers like Naho.
- Hidden Buxom: As part of a Quiz game Naho's group was taking part at so they could retrieve Kibiki from Sachiko's clutches, they need to find out who has the largest chest size out of all 3 girls present. Naho and Sayaka have a hands-on approach to find out Aiko's and she has, in fact, the largest chest out of all of them, which her outfit does a good job at concealing.
- Hidden Heart of Gold: Revealed in Blood Drive. At one point she unflinchingly mused about trapping Naho's spirit in a spiritual item to make it a rare "talking spiritual item". And one glance at a picture she took with Naho and Sayaka and her reaction shows that, deep down, she considered Naho a friend and misses her. And after Sayaka's corpse is found and she's running away from Darkening!Inumaru, she cracks and voices that she could care less about money and spiritual items, and that all she wants is see Naho and Sayaka again.
- It's All About Me: She only cares for her personal gain, and is even willing to do Sachiko's bidding if it means getting her hands on spiritual items.
- Off with Her Head!: Happens to her in Blood Drive, but after Sachiko sends Ayumi back in time, Ayumi is able to prevent it.
- Smug Snake: Every time she finds herself in a position above other people, particularly Naho, she pushes their buttons for her personal amusement. When she's put in a lower or uncomfortable position, she cracks considerably, which shows in her reaction to being on the receiving end of the abovementioned Skinship Grope.
- Vitriolic Best Buds: Her reaction when looking at a picture of her with Naho and Sayaka implies that she saw Naho in this regard. Made all the more clear when she lets out that all she wants is see her dead friends again, spiritual items be damned.
