Main Characters
The two lead characters of the story, Shinpei and Ushio Shinpei Ajiro
Shinpei Ajiro
Voiced by: Natsuki Hanae (Japanese), Stephen Fu (English), Uraz Huerta (Latin Spanish), Alan Moo Malvárex (Latin Spanish, child)
A young, yet intelligent boy who lost his parents in an accident and was taken in by the Kofune family. He left the town around 2 years before the story to start high school and culinary school in Tokyo, returning after hearing of Ushio's death. He learns he is in a time loop, returning in time whenever he dies.
- Accidental Pervert: When we first meet him, he awakens from a strange dream where he talks with Ushio in a panic and ends up shoving his face into the breasts of Hizuru, who's sitting across from him, leading to him getting slapped for the first time in his life despite his attempts to apologize. He ends up doing this again after his first death.
- Amateur Sleuth: You'd almost think Shinpei has gotten involved with time loops and mysterious monsters before with just how quickly he figures everything out and manages to investigate the shadows as effectively as he does, with him even being able to realize that Mio was copied the day before he arrived for the funeral based on the real one wearing striped panties when they met upon his return and the shadow wearing white ones when she killed him in the second loop. Justified in that he's a fan of Hizuru's mystery books.
- Badass Hairstyle He puts his hair up in a samurai topknot when he gets serious.
- Catchphrase: "Be objective", a mantra to calm himself in times of crisis to access something with a clear head.
- Conveniently an Orphan: Shinpei was orphaned 10 years before the story and taken into the Kofune family, being raised alongside Mio and Ushio.
- Fingore: Suffers this in the fourth loop when he tries to kill Haine with his nail gun; Shide slices the nail gun in half, along with all of Shinpei's fingers.
- Heroic BSoD: Suffers this big time at the end of Episode 18 when he loops back to when he and Ushio saved the kids from the Shadow of their teacher, after being impaled by Shide, only to find that Ushio is not with him, on account of her dying before him in the previous loop. He was ready to die once to learn the truth about his parents, but not ready to lose Ushio.
- Magical Eye: Ever wonder why Shinpei is drawn with different colored pupils or irises? Remember when he talked to Ushio in Chapter 1 and she gave him a gift? That was the eye of Haine, the original shadow.
- Necessary Drawback: To prevent him from just killing himself every time a loop goes wrong, his "save point" is moved forward slightly every time he resets, meaning the more he dies the less time he'll have to fix things.
- Ship Tease: He gets a lot of romantic teasing with Ushio.
- Tragic Time Traveler: The main premise of the story is that Shinpei somehow finds himself in a time loop while heading back to his hometown to attend the funeral of his childhood friend, Ushio, and if something happens to him that would've otherwise killed him? He gets sent back to the ferry heading towards his hometown. From there, he goes through the same day multiple times, trying to piece together why Ushio died and what's going on while also dealing with hefty baggage along the way.
- Unusually Uninteresting Sight: For the first couple episodes, his right eye was of a different shade of blue than his left eye, and nobody noticed in light of Ushio's funeral. He notices it after finally looking at himself in the mirror, but doesn't understand what it's for. His right eye is what allows him to time loop.
Ushio Kofune
Ushio Kofune / Shadow Ushio
Voiced by: Anna Nagase (Japanese), Emi Lo (English), Diana Nolan (Latin Spanish), Sarah Mendoza (Latin Spanish, child)
Ushio acts as the female lead of the story. Her death acts as the starting point for our story, with Shinpei returning home to attend her funeral.
By the time the story starts, however, her Shadow is able to roam free on the island, and reuniting with Shinpei, she joins the time loop with him to save the island with him.
- Action Girl: Normal Ushio knows how to take care of herself just fine, having punched a couple kids who were bullying Shinpei when they were kids. But Shadow Ushio is on a whole different level, wiping out multiple Shadows with ease, going toe to toe with Shide, and foiling Haine's plans for the festival every step of the way. Without her, Shinpei wouldn't have gotten as far as he did.
- Bait-and-Switch: She outsmarts and bamboozled Shide brilliantly in Episode 15. Any part of her hair can be used to copy anything, even if it's a single strand. During her fight with Shide, she gets stabbed and burned by Shide who wants to deprive Shinpei of his strongest ally, but that was actually a clone, made of Ushio's entire hair except one single strand that fell off. That strand transformed into the real Ushio, and she stabs Shide from behind with a single punch. It was a masterful fake out that contributed greatly in the heroes' first ever true win against Haine and Shide, and it was a great example of her becoming smarter and craftier as time moves forward.
- But Not Too Foreign: Half-Japanese and half-French. She got bullied in her childhood due to this.
- Chainmail Bikini: Her battle outfit is the one-piece swimsuit the original Ushio wore the day she drowned. Shadow Ushio justifies that since she is a shadow and all damage done to her body is easily fixable, it is pointless to wear clothes that will only hinder her movement.
- Character Development: Shadow Ushio does change quite a bit as the story moves forward. At first, she's convinced she's the original, and for a while, struggles with the reality that she's just a copy. But when the Original Ushio accepts her as part of her no matter what, Shadow Ushio in turn accepts and embraces that she is Ushio, even if she still had some self-doubt when face to face with Ushio's old friends who only know her as a Shadow. She also starts off none too bright, but then unusually, quickly learns to adapt to the times, becomes more observant and less impulsive, takes full advantage of her ability to copy anything even beyond Haine and Shide's expectations, and becomes a master at improvising even mid-fight.
- Ushio also learns to be more ruthless against her enemies as time moves on. She's a kind person behind all that rambunctious and irreverent energy, and it hasn't always helped her. In Episode 15, after a tough battle, Ushio has a chance to finally kill Haine (who is disguised as Shiori by this point), but she hesitates. She doesn't see a monstrous enemy to be slain. All she sees is a broken, bloodied child trying to survive, and that brief moment of hesitation allowed Haine and Shide to escape in the end. She gets a second chance not too long after in Episode 18, when she and Shinpei finally confront Karikiri who is actually Shide. Shinpei planned to shoot him after learning why his parents were killed, but even after getting an answer, Shinpei hesitates because Karikiri still seemed human. But Ushio made that same mistake before and learns from it, swiftly slicing Karikiri's head off without mercy or pause.
- Close-Call Haircut: Loses part of her hair (a precious resource, since she can use it to clone things and attack) during the fight against Shide in the gym, leaving her with shoulder-length hair for a while.
- Did Not Think This Through: Thinks that wearing a haori and a festival mask will be enough to conceal her identity from her sister and friends - ignoring that her distinctive blonde hair and bathing suit are still visible, in addition to her voice being instantly recognizable.
- Deuteragonist: The story is as much about Ushio as it is about Shinpei. In some ways, she's even more vital to the plot because she's the only reason he can time travel to begin with.
- Dumb Blonde: It's hard to say if it's indicative of the real Ushio, but her shadow hardly presents herself as a paragon of intelligence. Along with stealing Shinpei's phone and casually trying to say hi to Mio despite just being told that she, or more accurately her original self, died fairly recently, her idea of a disguise for interacting with Mio without getting figured out is a festival mask that does nothing to hide her distinctive blonde hair, and a haori that she doesn't even bother to close. Possibly justifed, since she doesn't actually know about the shadow situation (not even that she is one) and isn't too bothered with trying to keep her identity hidden, since she thinks her sister and friends will be happy to see her again. Mio's very hostile reaction to seeing her clearly catches her by complete surprise. This is ultimately subverted the more the series goes, and Ushio quickly becomes one of the smartest fighters in the story, even if she is still impulsive.
- Exact Words: A more lowkey and downplayed variation. Shinpei's eye belonged to Hiruko and Ushio gave it to him so he could time loop. How did she do that? That eye belonged to Hiruko. Ushio is Hiruko too, more specifically the red eye that detached itself after Haine's Horror Hunger caused her to go berserk on Ryuunosuke.
- Foreshadowing: The original Ushio's body is still preserved even after death. If Ushio's body is gone, then Shadow Ushio loses her Healing Factor. It's even used as bait by Shide in Episode 16, who sends Negoro to try to lure them into what Shinpei realized was a trap. But Ushio's body is still intact, and Negoro did nothing to harm it. Why not finish the job and cut off Shadow Ushio's Healing Factor? Because Shadow Ushio is part of Hiruko, separated after Haine killed Ryuunosuke. Harming Ushio would harm Haine, and in turn, Hiruko, and that is not what Shide needs.
- In Episode 17, Ushio realizes that she's Red Eye, the part of Hiruko that split off from Haine after Ryuunosuke's murder. During a contemplative moment between her and Shinpei, Ushio's eye glows red and she starts talking completely differently, which Shinpei notices immediately. He couldn't see the red eye but he asks why her speech pattern changed so drastically and suddenly, but she couldn't remember even though it happened mere seconds prior. What's up with that? The following episode doesn't address it either. Instead, by the end of Episode 18, Karikiri stabs Ushio's shadow and seemingly kills her for good, depriving Shinpei of his greatest ally and best friend. Turns out, her being Hiruko's disembodied Red Eye means Ushio's Achilles' Heel is not her physical shadow, but instead Shinpei's eye, the same eye he uses to time loop and the same eye that Ushio gave to Shinpei to stop Haine. If he doesn't die permanently, she doesn't die either.
- It goes even deeper. It's established early that Shinpei can time loop, but how or why isn't explained until after. Haine later grabs Shinpei's arm, leaving a black mark which she uses to follow Shinpei after every time loop and retain her memories. But she's not the only one who can loop with Shinpei - Ushio can too, in fact she can physically re-manifest herself with Shinpei in any loop as long as she's with him, but she also has the power to share her memories with everyone, allowing her to update them without exposition dumps. Ushio was never a normal Shadow but even that is quite powerful. What makes her so special? We find out Shinpei's eye actually belongs to Hiruko, the goddess using Haine as a host, and Shadow Ushio gave it to him specifically to use it to stop Haine. How the hell did she do that? Ushio is in fact the Red Eye that split off Hiruko when Haine killed Ryuunosuke.
- Despite being a Shadow, she's the only one not affected by Haine's orders. When Shide tries merging her with the other Shadows, Ushio forces herself out and punches him, proving she's something special. As the only one who doesn't obey Haine, Ushio learns she can also cut a Shadow's ties to Haine, as seen with Tokiko's bodyguards and Shadow Mio. This goes beyond her not being a normal Shadow. She is Hiruko, specifically the right eye that was cut off when Haine ate Ryuunosuke. Of course she would have the power to cut them off from Haine.
- Shadows die when their physical shadows are killed. Their bodies are just projections otherwise. In Episode 21, after Shide stabs her shadow and basically kills her, Ushio copied her own memories and transferred them to a seashell just before she disappears. Haine knows the seashell is Ushio and Shinpei thinks Haine believes Ushio is still alive. He asks Shadow Mio to scan the seashell, but Shadow Mio says she can't because Ushio made it so no Shadow could scan it. Just like Haine. It's the second time Ushio did something that seemingly only Haine could do, having previously severed Ros and Guil's connection to Hiruko. This isn't an accident: Ushio's true Achilles' Heel is not her own shadow, but Shinpei's eye, because that eye is actually Red Eye, the part of Hiruko that split off after Haine killed Ryuunosuke.
- Fusion Dance: It is implied that the Ushio in the final dimension is a mix of both the original Ushio and her shadow version, as she has the memories of the latter even in a world where shadows never existed. This contributes to the theme that there was never any actual difference between them and that Shadow Ushio was still Ushio regardless.
- Genki Girl: A more tomboyish version. She's cheerful, bombastic, and very in-your-face especially whenever she's happy or excited about something.
- Good Is Not Soft: She's a Nice Girl with a ton of heart, passion, and empathy behind her at times rough exterior, but she learns to be more ruthless, more duplicitous, and more brutal against her and Shinpei's enemies, because she learns the hard way that showing compassion to monsters only lets them get away and continue making other people suffer.
- "Groundhog Day" Loop: As it turns out, she's also in something of a timeloop alongside Shinpei, remembering things from previous timelines. Unlike Shinpei though, she has the added ability to transfer her memories to others, which is helpful in recruiting allies.
- Hot-Blooded: Loud, feisty, and aggressive, Ushio is brimming with energy no matter who she's with or where she's at.
- Humanoid Abomination: Even more so than the other Shadows, Ushio is a piece of Hiruko's soul split apart and turned into its own fully sentient being. Ushio realizing her body was born from Haine leaves her shaken and scared, but she takes full advantage of that connection every chance she gets.
- Impaled with Extreme Prejudice: At the end of Episode 18, Ushio thinks she's killed Karikiri (after learning he's Shide), and so lets her guard down to call Hizuru to confirm what just happened. But then Karikiri stabs her shadow and drags it along the floor. Ushio's body is sliced, blood gushes out, and she disappears. When Shinpei loops back time, Ushio is nowhere to be seen.
- Jacob Marley Apparel: The default swimsuit outfit she wears for almost the entirety of her screentime is the clothing article she died in.
- Ms. Fanservice: The original Ushio was a curvy, athletic, attractive blonde, and as she died while out swimming, her shadow is dressed in the same one-piece she was wearing at the time, which the camera loves drawing attention to. Helps that the Shadow is an Innocent Fanservice Girl who sees nothing wrong with being the subject of a constant Walking Swimsuit Scene.
- Only Mostly Dead: It's complicated. When Karikiri stabs Ushio, effectively killing her, Ushio copied her memories and planted them onto a seashell. She has no body, and her memories are just a fragment, but the seashell glowed brightly whenever Haine got closer to Shinpei, causing Haine to think Ushio was still alive. In a way, she kind of is. Shadow Mio explains that the seashell, meaning Ushio, is reacting out of anger, still trying to protect Shinpei after all this time. That's when Shinpei realizes that the Shadow Ushio originally wakes up on the day of the festival without her memories; he just kept looping time before we got to the day of the festival after the first try. All Shinpei has to do is get the seashell to Shadow Ushio to restore all her memories, thereby "reviving" her by transferring that fragment onto a different body courtesy of time travel.
- Physical God: While Shide and Haine first see her as a defect, they soon realize there's something special about Ushio, something they couldn't quite understand until much later. Her ability to not only resist, but outright ignore Haine's commands, as if she was immune to the goddess's commands, is when everyone realizes she's no ordinary Shadow. This becomes doubly so when that's because she's actually Hiruko, or rather, the piece of Hiruko that separated from Haine after Ryuunosuke died. That also retroactively explains why Ushio was even able to give Haine's eye to Shinpei: that eye allows him to time travel, and that eye is as much part of Ushio as it is part of Haine. It also explains why she can cut off other Shadows: they're still following Hiruko after all, just a different piece of Hiruko.
- Prehensile Hair: Shadow Ushio can control her hair, which cuts like a blade. She is shown to be able to utterly destroy some shadows using it.
- Stepford Smiler: In Episode 16, she learns that killing Haine would kill all Shadows, including her, Ushio hides behind a sad smile while saying she was supposed to die two days ago, so she's been living on bonus extra time anyway. She's clearly hurt, but hides the way so Shinpei's resolve doesn't falter. It works.
- Token Heroic Orc: Unlike other shadows, Shadow Ushio does not feel the need to replace the original and is easy to befriend. It's theorized that it is because she is faulty to some degree and can't hear the same commands other shadows can combine with Ushio's already benevolent personality. Unlike the other shadows, she is actually part of Haine, not just born from her. The section that separated from her when Ryuunosuke got killed? That part turned into Ushio.
Friends and Allies
Friends who team up with Ushio and Shinpei Mio Kofune
Mio Kofune
Voiced by: Saho Shirasu (Japanese), Merk Nguyen (English), Regina Carrillo (Latin Spanish)
Ushio's younger sister, she acts as a foil for Shinpei and Ushio
- But Not Too Foreign: Half-Japanese and half-French, like her sister, though she took more after their mother in appearance, with only her blue eyes showing her French ancestry.
- Damsel in Distress: Mio's main role in the manga is to be in peril for Shinpei and Ushio to save. This is especially true in the early loops, where Shadow Mio was a major threat. Later loops, when she is properly informed of the
- I Am Not Pretty: She inwardly loathes the fact that she's more of a tomboy than her sister, which is part of the reason why she's hesitant to tell Shinpei how she feels about him.
- Ms. Fanservice: From her introduction onward, Mio is the subject of a number of different fanservice scenes. Probably too many, being one of the younger cast members.
- Obliviously Beautiful: Because she compares herself unfavorably to her sister, she fails to comprehend that she herself is quite attractive, enough to make both Hishigata siblings fall for her.
- Unrequited Love: She has a blatant crush on Shinpei, which is why she refuses to refer to him as "brother" and why she refuses Sou's advances.
Hizuru Minakata
Hizuru Minakata
Voiced by: Yōko Hikasa (Japanese), Jenn Wong (English), Jennifer Medel (Latin Spanish)
A famed writer under the pen name Ryuunosuke Nagumo.
- An Arm and a Leg: In the fifth loop, when fighting Shadow Shiori, Shide appears and cuts off her arm before smashing her head.
- Awesomeness by Analysis: She's able to realize that Shinpei's in a "Groundhog Day" Loop just by analyzing his behavior, and noting how he knows a lot about her despite them not meeting before his Accidental Pervert moment on the boat, having had Ginjirou make sure he wasn't a shadow beforehand.
- Casual Kink: When younger, she would openly read erotic novels in public. A flashback shows that Ushio once asked her to read what she was reading for her, immediately starting to pronounce about a sex scene between a girl and her step-father before being forcefully cut off by her friend.
- Half-Identical Twins: She and her brother Ryuunosuke are noted to be this.
- Hammerspace: Carries a sledgehammer around in her bag and uses to bash Shadows in.
- Killed Off for Real: Killed in chapter 113 after a fight with Shide, who had the foresight of fighting in a previous loop where they were evenly matched. Hizuru manages to transfer Ryuunosuke to Shinpei, however.
- Ms. Fanservice: The anime puts a lot of focus on her ample bosom.
- Shotguns Are Just Better: When she saves Shinpei in the third loop, she does so by repeatedly shooting Shadow Mio with a shotgun.
- Split Personality: Her brother's personality, Ryuunosuke, is copied by Haine and then reflected and stored within her, together with the super strength and speed of shadows. When she has to fight, Ryuunosuke takes over her body (signalized by tying her hair up).
- Tragic Bigot: Downplayed. While not opposed to working the Ushio's shadow, Hizuru is generally distrustful of Shadows and even ended her alliance with Shinpei in one loop as a result. This hatred seems to stem from Haine eating her brother when they were still friends.
- We Used to Be Friends: It turns that in the past, she was one of the few people who knew of Haine, visiting her often to hang out with her and give her snacks. This friendship tragically ends when Haine's Horror Hunger escalates to the point that she eats Hizuru's brother and gets discovered by her, causing a Sanity Slippage and Eye Scream.
- Write What You Know: In-Universe; her novel Swampman is explicitly based on the Shadows.
Tetsu Totsumura
Tetsu Totsumura
Voiced by: Yoji Ueda (Japanese), John Choi (English), Fabián Rétiz (Latin Spanish)
The perverted and cowardly local police officer of the island.
- Character Death: In the first two loops, he is killed by Shadow Mio so she can get his gun from Shadow Totsumura.
- Cowardly Lion: Totsumura is just about the textbook definition of this. While normally cynical and cowardly, when push comes to shove, he is able to step up.
Ginjirou Nezu
Ginjirou Nezu
Voiced by: Jin Urayama (Japanese), Tim Dang (English), Rubén Moya (Latin Spanish)
A former fisherman who helps Hizuru hunt down the shadows of the island
- Cold Sniper: Downplayed, he is quite level-headed and is a sniper for the group, but he can still be pretty explosive when around Hizuru.
- Product Placement: Ginjirou, within a few panels of his introduction, puts his SOREL boot label smack in the center of the page.
- Staking the Loved One: His wife was replaced by a shadow a year ago. He kept it imprisoned for a time, before killing it for good.
Sou Hishigata
Sou Hishigata
Voiced by: Kensho Ono (Japanese), Jason Jin (English), Luis Navarro (Latin Spanish)
A childhood friend of the Kofune family. The eldest son of the doctor family of the island.
- Batter Up!: As a former baseball club team member, he has a metal bat and it becomes his go-to weapon in one of the loops.
- Heroic Sacrifice: In the festival loop, he dies by being axed on the brain by his own Shadow while protecting Mio. His Shadow remarks that this makes them incredibly cool to die that way. He does this again in the following loop when he is killed taking a bullet for his sister.
- Locked Out of the Loop: His family has been serving Haine for generations, and his mother is actually a Shadow that replaced the original one. He was never told this because his father judged him too weak to deal with it and put Tokiko in charge of such.
- The Unfavorite: His father clearly looks down on him and prefers Tokiko, finding him to be too weak to be a doctor for not being able to deal with death. Exemplified by the fact that he skips him and makes Tokiko his heir instead.
- Unrequited Love: For Mio. In one of the loops, he confesses to her during the festival, only to get turned down for what doesn't seem to be the first time.
- White Sheep: The most benevolent member of the Hishigata family, as he is out of the loop about his family's collusion with the Shadows.
Tokiko Hishigata
Tokiko Hishigata
Voiced by: Maki Kawase (Japanese), Jennie Kwan (English), Nycolle González (Latin Spanish)
A childhood friend of the Kofune family and Mio's best friend. The youngest daughter of the doctor family of the island.
- The Atoner: Is this once she learns the truth. She even thanks Shinpei for forgiving her near the end of the series.
- Closet Gay: She's in love with Mio but the closest she comes to telling anyone is allowing Shadow Mio to copy her, both as part of an overall plan and because she wanted Shadow Mio to see "the deepest parts" of her.
- Eyes Always Shut: Is normally depicted this way, except when she's angry, agitated or otherwise feeling strong emotions.
- Heel–Face Turn: Learning that Haine intends to betray her and kill her entire family to feed, she joins the heroes from the sixth loop onwards, and is able to control two Shadows to fight for her.
- No-Sell: When revealing her collusion with the Shadows, Shinpei makes the logical deduction and shoots dead center at her shadow. However, it doesn't work on her... because she's human.
- O.O.C. Is Serious Business: Normally calm, cool and collected, even when revealing her true colors to Ushio, Shinpei and her brother in the caves beneath the island, she utterly blows up at Sou when the latter confronts her about her involvement in Ushio and Shiori's deaths, showing just how much anguish and resentment she has been suppressing until that moment.
- The Resenter: Is this toward her brother, as she hates the fact that he has been completely unaware of their family's legacy of serving Haine for generations and therefore free from its burden, whereas she was chosen by their father to be his heir, with all that entails.
- Shout-Out: The two Shadows she controls are called Rosencrantz and Guildenstern, the titular leads of the play Rosencrantz and Guildenstern Are Dead
- Stepford Smiler: She portrays a calmly cheerful personality, but as shown in episode 12, it hides the emotional toll that her Villainous Legacy is taking on her.
- Summon Magic: She fights by commanding Ros and Guil, two wild Shadows that obey her commands and are normally transformed into pacifiers when not active.
- Walking Spoiler: It is hard to talk about her without revealing she and her family are in league with Haine, as well as her immediate betrayal by her.
- You Have Outlived Your Usefulness: In two loops, she is killed by Haine and Shide when she is no longer of use to them. Learning about this in later loops has her changing sides to side with the heroes.
Townfolks
Residents of Hitogashima. Alain Kofune
Alain Kofune
Voiced by: Tesshō Genda (Japanese), Ping Wu (English), Héctor Estrada (Latin Spanish)
The father of Ushio and Mio.
- Spell My Name With An S: The English version of the manga translates his name into Alan while the official anime site points to the romanization of his name as Alain.
- Took the Wife's Name: As evidenced by the fact that his surname is "Kofune" rather than something French.
Shiori
Shiori Kobayakawa
Voiced by: Rie Kugimiya (Japanese), Giselle Fernandez (English), Araceli Cedillo (Latin Spanish)
The young daughter of the store-owners of the island, and a friend of the Kofune girls, who believes she is haunted by the Shadows.
- Dead All Along: The real Shiori was killed by a shadow, specifically Heine, together with the real Ushio, and the current one is actually Heine's new body.
- In Spite of a Nail: The epilogue shows that she's practically the same despite Ryuunosuke being her father instead, now having a version of Haine as her sister.
- Walking Spoiler: Hard to talk of her without saying she is already dead and replaced by an extremely powerful shadow.
Dr. Hishigata
Seido Hishigata
Voiced by: Akio Ōtsuka (Japanese), Sean Burgos (English), Pisano (Latin Spanish)
The doctor of the island and Sou and Tokiko's father.
- Abusive Parent: Very openly berates his son, considering him a weakling of the family, telling him to give up on medicine. In a loop where he learns that Tokiko ditches his side after learning that the Shadows will betray them, he refuses to believe and shoots her to kill, though she is saved by Shadow Mio.
- All for Nothing: Everything he did so his family could reunite as Shadows was pointless, since he was already immune.
- The Atoner: Teams up with the heros after learning the truth. He makes a point to apoloize to Sou after his Heel–Face Turn and tells Shinpei the truth about what happed to his parents.
- Heel–Face Turn: Once Shadow Chitose, his wife, is released from her relationship with Haine, she calls him out on his behavior towards their children and makes him set things right.
- Kick the Dog: Shoots his own daughter when she refuses to follow his plan, thankfully Shadow Mio had replaced her.
- Locked Out of the Loop: He was never told that he is immune to Shadows, foiling his plan to turn his family into shadows so they can live forever.
- Parental Favoritism: Favors Tokiko over his son Sou enlisting her into the Ancient Conspiracy to serve Haine.
Masahito Karikiri
Masahito Karikiri
Voiced by: Katsuyuki Konishi (Japanese), Kaiji Tang (English), Oscar Gómez (Latin Spanish)
The local head priest.
- Foreshadowing: In Episode 1, Karikiri is the only character who says Shinpei-kun, everyone else says Shinpei-san. The only other character who says Shinpei-kun is Shide, but we don't know that until much later.
- Half the Man He Used to Be: Not his whole body, but Ushio does cut off the top half of his face in Episode 18.
- Me's a Crowd: Ushio slices Karikiri's face, then a second Karikiri shows up to stab her. That's because he is Shide, who can essentially clones himself every time Haine gives birth to a child and copies his memories into that child.
- Motor Mouth: Has a habit of talking non-stop when he gets going.
- Five-Second Foreshadowing: He talks about Shinpei about his love of Final Fantasy 7 and how wistful he is that the remake hasn't been released yet. That is because he intends to end the world the next day, not giving time for the game to be released.
- Shout-Out: When talking with Shinpei, he mentions loving RPGs, and was really looking forward to the release of Final Fantasy VII Remake, being a big fan of the original. He also mentions loving the post-apocalyptic feel of the original game, mentioning how it makes him think of the end of life.
Shadows / Spawn of Haine
Other Shadows
In General
- Always Chaotic Evil: Seems to be the case at first. Then Shadow Ushio and Shadow Mio both make it clear that they're fully capable of morality, and a willingness to logically work towards a better solution.
- Attack Its Weak Point:
- Shadows' real bodies are their actual shadows on flat surfaces, hitting their 3D body does damage but not much as they quickly heal and can't be killed by that. The way to actually kill them is to hit them on the shadow in a way that would kill the actual body.
- Shadows release a flash of light when copying data, much like a photograph, to absorb data, but while they're absorbing, they stand still and are defenseless to attacks.
- Doppelgänger: They are beings that take the form of people they see and while they foreshadow people's death like the original legend, it is because they take it upon themselves to kill and replace them.
- Humanoid Abomination: While they are already, normally, strange by their very nature, wild Shadows look like a bizarre black mess of flesh. A non-wild Shadow when pulling out all the stops to fight, will make its body and limbs long and twisted and look like a Necromorph.
- Kill and Replace: Once a Shadow copies someone, they intend to take over that person's identity. Subsequently, they call shadows to do the same to that entire family. This is because once they take the form of someone, they have six days to kill the original before dying.
- Nightmare Face: Shadows can make, bizarre, unsettling faces at times, especially when they are either upset or failing to pretend to be human.
- Ominous Visual Glitch: In the manga, shadows are depicted by having visual glitches on their body, especially when they're harmed in some way.
- Voluntary Shapeshifting
Shadow Mio
Mio's Shadow version.
- Cute and Psycho: Like Mio, she is a cute and peppy young girl, but unlike her, she is driven to kill the original and everyone in her way.
- Heel–Face Turn: Ushio breaks the connection with Haine, turning her into an Ally in chapter 83.
- Starter Villain: She is the first threat the heroes have to deal with in her quest to kill Mio. In the first visit, she kills Mio, Hizuru, and Shinpei, which kickstarts the time loop, and she continues being a major threat up until the introduction of Haine, which surpasses her.

- Alas, Poor Villain: During the final fight, she is turned into a pitiful, fetus-like being that Shide forcibly joins her to use her power and is constantly in pain, begging Shide to stop and let her heal. Ushio takes care of her like a baby and gives her a peaceful death by deleting her from the past.
- The Chessmaster: She's much smarter than she looks. She copied Shinpei, and therefore created Shadow Shinpei, but absorbed the latter into her body along with the rest of the shadows (minus Shide who stood guard and Ushio who escaped). After Karikiri stabbed Ushio at the end of Episode 18, Haine transferred back in time but manifested Shadow Shinpei as her new body. Because it has Shinpei's data, it also has Shinpei's intelligence, and she uses that to lure the main cast out to the beach so Karikiri can try to kill them, namely Hizuru.
- Creepy Child:
- Hiruko usually takes on the appearance of Haine, who appears to be a young girl.
- She has also taken the form of Shiori, a grade-schooler, making the little girl one of the most threatening shadows the heroes have to deal with.
- Dark Lord on Life Support: Haine's body is so weak it can barely walk and stays in an underwater cave hooked to an IV, eating whenever possible. It is why she decides to get a new body in the form of Shiori.
- Death Seeker: After Shide's defeat, Hiruko pulls the group back to the point their whale form washed up on Hitogashima, so Shadow Ushio can erase the god for good.
- Ditto Fighter: Towards the final loops, she copies Shinpei, which gives her insight about his personality and thoughts, allowing her to plan on equal grounds to Shinpei as they try to Out Gambit each other.
- Eldritch Abomination: A shadow being/deity of possible alien origin that controls a group of humanoid abominations on the island and shows powers even over time and space.
- From Nobody to Nightmare: The original Haine was an ordinary daughter of a fisherman who touched the original Hiruko in the form of a whale.
- Good Wears White: The original Haine personality wears a white version of her outfit she manifest and is firmly on Shinpei's side.
- Horror Hunger: 14 years ago, Haine was suffering the effects of the Shadow's increasing hunger. Because Shadows eat information, her attempt to fill herself with food failed, culminating in her killing Ryuunosuke and eating his body.
- I Will Find You: Her handprint on Shinpei's arm allows her and Shide to track him down and kill him and everyone else. They eventually exploit this by using him as a vessel to speed up the process of Shide's destruction of the world.
- Literal Split Personality: Her guilt at killing Ryuunosuke caused a portion of her data containing the original Haine's peronality to fragment off. This fragment would become Shadow Ushio and in the World beyond Time, the original Haine would fully manifest as a separate being from Hiroku.
- Monster Progenitor: She is the mother of all shadows, and is the only one that can continuously birth more shadows. In all other cases, each shadow can only create one more and that newly birthed shadow can't create any, making her existence vital for the survival of the species. Killing her will cause all shadows to die out.
- Mystical White Hair: She's white-hair and is an Eldritch Abomination that spawned the Shadows. Flashbacks show her human self had brown hair impling it became white at some point.
- Nice Job Fixing It, Villain: When she killed Ryuunosuke, she was so overcome with grief that she expelled that side of her, which manifested as Red Eye, as well as Ryuunosuke's data which she had absorbed after eating him. But here's the catch: Ryuunosuke's data went forward in time by two seconds, then printed those two seconds, meaning Ryuunosuke's soul is permanently ahead two seconds into the future, and because Hizuru was nearest to him, Ryuunosuke was able to merge with Hizuru and control her body from two seconds into the future. This means the only reason two of Shinpei's toughest allies are even able to fight Shadows so fiercely is because of Haine's power to begin with, something Haine is not amused by.
- Psychopathic Womanchild: Hiruko spent hundreds of years stuck in a childs body and is largely manipulated by Shide towards his goals despite being the one with greater power. In the present she's much more unstable and it's implied that losing the original Haine personality was the cause of this.
- Retgone: After Shadow Ushio deletes Hiruko in the past before it copied Haine, erasing its influence on the timeline. Persumably the original Haine Karikiri lived out the rest of her life as an ordinary girl and we see she's been reborn in the present as as Haine Minakata, Ryuunosuke and Asako's daughter.
- Spacetime Eater: The moment that she and Shide find out that Shinpei's been not only going back in time, but also to dimensions that start him back earlier, she gets the idea to exploit this in order to prevent Shinpei from ruining their plans of destroying all reality in Shide's bid to find death.
- Spell My Name With An S: The English version of the manga translates her name into Haine while the official anime site points to the romanization of her name as Heine.
- Took a Level in Jerkass: After expelling her original personality , she became much crueler and callous best explified by her noting that she will kill Hizuru if she comes back to Hitogashima.
- Tragic Dream: Back when she was just a girl named Haine Karikiri she just want to spend her life with Shidehiko Hishigata.
- Used to Be a Sweet Kid: Back when she and Hizuru were friends, she was more of a Cheerful Child who enjoyed hanging out with her Only Friend. Then her Horror Hunger compelled her to kill Ryuunosuke and it was all downhill from there.
- Villain Forgot to Level Grind: Subverted. Once she realizes that Shinpei is on a time loop, learning things to use against her on a subsequent one, she begins to follow him on said loop, complicating his plans as she reveals that she can also retain information.
Shide (SPOILERS UNMARKED)
Shide / Shidehiko Hishigata / Masahito Karikiri
Voiced by:Katsuyuki Konishi (Credited as unintelligible garble) (Japanese), Kavindar Singh (English), Pisano (Latin Spanish)
A massive four-armed shadow that acts as Haine's servant.
- All for Nothing: Mocks Shinpei for this after impaling him and killing Ushio during the second to last loop, boasting about how he'll win in the end and that Shinpei will die before being able to witness it. With heavy implications that neither Tokiko or Hizuru, who also accompanied Shinpei, survived this particular encounter much long after.
- Big Bad: By the endgame, it is clear he is the true mastermind behind the plot and is the one using Haine for his own purposes.
- Body Back Up Drive: Shide use his previous bodys as back ups during the story having both his current body and his previous form availible. When Usio kills one in the seventh loop he promptly kills her using the back up. Dr. Hishgata mentions that he had more back up bodies, but they were destroyed during the war. It's eventually shown he still has access to his original human body, after both of his main bodies are destroyed but its basically a mummified corpse and he can only use it to remotely control his armor in the other world.
- Can't Kill You, Still Need You: Tries to do this to Shinpei during the fourth loop, by killing everyone who could prevent his ultimate destruction of the world and have him witness the death of humanity helpless and broken. What he didn't account for was Shinpei killing himself, allowing him to go back and try again. Both he and Haine eventually drop this when they realize they can just kill Shinpei by making him loop until he can't loop anymore, making his final death permanent and successfully destroying the world and all of spacetime.
- Half-Human Hybrid: He is a shadow-human hybrid born from the original Shidehiko having a child with Haine's physical body and passing down his personality and memories to each one. when he dies.
- It's All About Me: He is incredibly arrogant and self-centered and sees everyone, even Haine, as existing to serve him and realize his plans. Said plan involves causing the destruction of the world, and reality as a whole once it's revealed that the time loops are just alternate realities, because he wasn't as immortal as he thought he was and thus wouldn't be able to see humanity's end naturally. Even the concept of replacing all life on Earth with shadow duplicates turns out to be a lie when he reveals that he just wants everything to die to satisfy his Death Seeker tendencies, including the shadow clones.
- Long-Lost Relative: He is a distant relative of the Hishigata family, having separated from that family to focus on taking care of the shrine.
- Meaningful Name: The four-armed shadow, Shide. As Hizuru mentions, it is written in a similar way to "4 arms" ("Shi" is a pronunciation for the kanji for four, 四; "de" is a pronunciation for the kanji for arm, 手).
- Shide is also a zigzag paper, usually found and used in Shinto rituals.
- My Grandson, Myself: He is been pretending to be his own descendants to hide his immortality. He does this by impregnating Haine, which creates a perfect clone of him and having Haine copy his personality into this younger body.
- Nightmare Face: Shows one in Episode 18, in his form as Masahito, when he explains why he killed Shinpei's parents. Specifically when he asks him if he would have been "happier" if he had turned them into Shadows instead.
- Omnicidal Maniac: He intended to live forever and experience the destruction of the world, but as Haine's powers waned and she can no longer make clones of him, he decides to end the world already so he can still go through with his plan.
- Really 700 Years Old: By using Haine to clone himself into new bodies, he managed to keep alive for 300 years.
- Spacetime Eater: Becomes his goal once he realizes that Shinpei's power not only reverses time, but sends him into an Alternate Timeline altogether. And uses this to accelerate his eventual death of everything, and himself, as fast as possible.
- Walking Spoiler: It's impossible to really talk about him without mentioning that he's actually Masahito.
- Would Hit a Girl: On top of his bid to destroy reality, he has zero issues killing Ushio, Tokiko, Hizuru or either Mio when they attack. He later forces Haine into his being despite her being in immense pain, not caring at all about what happens to her in the end.
