Note: Due to Amnesia: Later After Stories taking place after the Good Ending in Memories, all listed tropes and examples for Amnesia: Later will have unmarked spoilers.
Voiced by Kaori Nazuka (Japanese), Maggie Flecknoe (English)
The heroine lost her memories when the spirit Orion accidentally merged with her mind, taking up the space her memories would occupy. The two work together to figure out her identity and regain her memories, as Orion says he'll be pushed out the more she remembers.
Each of the routes alters her background and the depth of her relationships, but certain details remain the same: she works as a maid at the Meido no Hitsuji café, and she's enrolled as a first-year psychology student at Myouga University.
- Adaptation Dye-Job: Light-brown hair in the games. The anime added a pink gradient to her tips.
- Amnesiac Hero: Her titular memory-loss drives the plot.
- Amnesiac Lover: Each route has her be the girlfriend of the guy associated with it. Except for Ukyo, whose girlfriend she was in the previous rendition of the original world, and Toma, who lies to her out of a misconception of being kind to her.
- Audience Surrogate: Has little personality, making it easier for the player to insert themselves.
- Bandage Babe: Wears bandages over her injuries in Heart World. Waka tells her to feel free to keep wearing them after healing up, as they have attracted more customers. And Ikki admits that he's never thought about it, but that bandages on a young lady appear quite sexy.Ikki: Makes me want to unwrap them.
- Break the Cutie: Several routes put her through hell. She gets bullied and harassed in more than one route, and suffers from imprisonment in another.
- Canine Companion: Clover World had her own a dog called Kuro. Shortly before the route starts, Kuro got hit by a car and died from his injuries. Kent's rational view about it caused their biggest fight.
- Childhood Friends: With Shin and Toma. Their closeness depends on the route.
- Color-Coded Characters: Pink is used in manuals. Seafoam is her dialogue tag's color.
- Cover Identity Anomaly: Played with, as she's the right person. Her amnesia makes her mess up on details.
- Dead All Along: Joker World reveals her to have died, but was revived due to time-rewinds.
- Everything Is Trying to Kill You: Cars, trains, and motorcycles almost run her over, and Ukyo doesn't mind killing her himself. Joker World reveals this to be because she died in the original universe, and her continued existence is an anomaly. The universe is trying to fix this by throwing everything at her.
- Extreme Doormat
- Spade World makes her appear as one when it comes to Ikki and his fangirls. She has to remain meek around them, and even apologize for not waiting in her room as planned, but going out to look for Ikki when he's late for their fireworks date. Though this turns out to be a farce done to keep the fangirls in the dark about how well her relationship with Ikki is going.
- Diamond World shoves her firmly into this. She gets lied to and manipulated by Toma, drugged, and even locked into a cage. Nonetheless, she mostly remains physically passive about things.
- Fate Worse than Death: Some Bad Endings leave her in one. Spade World has her being rendered comatose and debilitated by Ikki's jealous fangirls. Clover World has her lose her sense of self after being locked into a hospital. And Diamond World has her become Toma's permanent prisoner and precious toy, her memory-loss worsening.
- Flower Motif: Roses. Her striker in the Air Hockey minigame has a red rose on it, and she wears pink roses on her clothes, and has them attached to her hat. The strap for her white bag is also in the shape of roses.
- Freudian Excuse: Spade World reveals her father to have been a notorious cheater and playboy, leading her to hate that type of person. This is also why she initially disliked Ikki, whose behavior reminded her of him.
- Hello, [Insert Name Here]: The player chooses her name.
- Heroic Mime: The games have none of her lines voiced.
- Idiot Ball: Keeps a firm grip on it in Diamond World. She trusts Toma a lot, and remains mostly passive upon being imprisoned. And when she manages to escape and gets injured outside, she chooses to head back to Toma's house and into the cage.
- Ill Girl: Gets dizzy upon regaining memories. She also gets sick in some routes.
- Informed Attribute: Diamond World has Toma say that the heroine can be quite terrifying when angry. It's apparently so bad that Toma gets scared of her. What anger the heroine ever portrays in the game is mild, at best, and nothing to be afraid of. Though it could be that Toma is referring to her having been much scarier as a child, and she has since mellowed out.
- Invisible Parents: Her parents never appear, except for her father near the end of Spade World.
- Kill the Cutie: Several Bad Endings involve getting her killed.
- The Many Deaths of You: Bad Endings like to kill her in a variety of ways, and getting crushed under a building structure is one of the more mundane ones. Joker World had her get caught in an explosion at her university, and dying of her sustained injuries several weeks later. And that's not getting into the way Ukyo likes to kill her himself.
- Missing Mom: It's implied that she might not have a mother. Spade World only mentions stepmothers, but other routes have only her father as a parental contact listed.
- Nice Girl: Her main personality that she shares in all routes, being a gentle, kind, and friendly woman.
- Nice Hat: Wears a black beret adorned with a few pink roses and white ribbons.
- No Name Given
- The player chooses her name as she has no official one.
- The anime expands her amnesia to include having forgotten her own name.
- Played straight, as she's completely immune to Ikki's hypnotic gaze. Though Orion says it's likely because he's currently merged with her, and his gaze does not work on supernatural beings.
- Spade World reveals that she's actually just as susceptible to it as any other woman, as she became smitten with Ikki the first time she looked into his eyes. However, she made herself immune to it through sheer willpower.
- Oblivious to Love: Oblivious that Toma has loved her for some time in Heart and Diamond World.
- Operation: Jealousy: Downplayed in Diamond World. Prior to losing her memories, the heroine was meeting up with Ikki and asking him for love advice, so that Toma will notice her romantically, and Ikki suggested she try to not meet him for a few months. Toma misunderstood and thought that she had started dating Ikki.
- Please Kill Me If It Satisfies You: Played with in Joker World. The path to his Good Ending has her offer Ukyo to kill her because it means he'll keep on living. Since he has died for her sake so many times, she wants to do it for him once.
- Please Wake Up
- Clover World has her say this to a badly injured Kuro.
- Joker World has her beg a dying Ukyo.
- Proper Tights With Skirt: Wears argyle-patterned tights◊ under her dress.
- The Quiet One: Barely speaks in this game, except for a few choice lines, and near the end of the routes.
- Shrinking Violet: Appears this way because she ends up quieter from her amnesia.
- Sick Episode: Spade World has her become sick, and the player can choose to have Ikki take care of her.
- Sickening "Crunch!": Bad Ending 2 in Clover World has Ukyo drop her off the hospital roof. A disgusting, wet crunch is heard before the screen turns red and switches to the Bad Ending image.
- Stock Shoujo Bullying Tactics: Spade and Diamond World have her get subjected to them, usually using the harassing phone calls or insulting e-mails. Diamond World goes so far as to have her contact information being posted online and getting e-mails from strange men that are asking for inappropriate and very sexual actions from her. Always courtesy of Ikki's fanclub members.
- Too Dumb to Live: Some choices are downright idiotic and lead to her death. Telling Ukyo about her connection to Orion in Joker World or choosing to spend the night with Ukyo in Heart World.
- You Are Not Alone: Joker World has her say this to Ukyo during his Good Ending. She tells him that he's no longer alone and doesn't need to carry his burdens anymore. She promises to stay by his side.
Tropes applying to Amnesia: Later
- Accidental Pervert: Walks in on Ikki mid-changing several times during his After Story.
- Amnesiac Hero: Downplayed in Shin's After Story, as she has recovered most of her memories. However, she's still missing some, including why she fell in love with Shin originally.
- Bedmate Reveal: Downplayed in Ikki's After Story, as the heroine doesn't recall that he slept next to her the night before right away. After a brief confusion, she doesn't mind.
- Cannot Spit It Out
- The flashback in Ikki's After Story reveals that she was pretty much in love with him in July, but had difficulty admitting it because she knew the relationship would end after August, and she didn't want to have to cry after the break-up.
- In his After Story proper, she stutters while trying to reciprocate Ikki's 'aishiteru'.
- Dating What Daddy Hates: Her father refuses to accept her relationship with Ikki and her living with him, saying that he acted just like Ikki in his youth, and that's how he knows that he'll grow tired of her soon. He comes around when Ikki proves the extent he has planned his future with the heroine.
- Feminine Women Can Cook: Does a lot of cooking in various After Stories.
- Ikki is impressed by her cooking skills, despite her being so young. She explains that she had to learn how to cook for herself because her father was often out dating women, and that it's all a matter of hard work.
- She teaches Kent how to cook in his After Story.
- Flowers In Her Hair: Wears a flower-shaped scrunchie in Toma's After Story.
- Limited Wardrobe: Played with, as she has more than her one outfit from Memories, but still wears one specific outfit for each After Story. She wears a dark blue dress with Shin, while she wears a light blue one with Ukyo. She wears a green one with Toma, and a red one with Kent. And she wears a white top, brown jacket, and a flower-patterned skirt with Ikki.
- Not So Different: Proves that she's actually just as obsessed with Toma as he is with her.
- Parents as People: Her father admits in Ikki's After Story that he's simply worried that her decisions could lead to her getting hurt, a worry shared by most parents.
- The Power of Love: States this to be the reason why she got so much better in school in Kent's After Story. She was scared of being separated from him for a whole year, so she sat down and studied herself crazy to make sure she'd join him on his study abroad.
- Silk Hiding Steel: Much more obvious than in Memories, now that she tends to lack the insecurity and doubt her amnesia had caused. She's much more open about her opinion, and isn't as easily confused, as well as being more willing to stand up for herself.
- Textile Work Is Feminine: Discussed and downplayed in Kent's After Story, as the heroine admits to Mine that she's not very good at knitting. And Sawa points out that the heroine will have work until Kent's birthday, so she wouldn't have a lot of time to create a handmade scarf. Due to lack of skill and time-constraints, she buys Kent a scarf for his birthday.
- Trauma-Induced Amnesia: Has repressed the events of August 25th in Ukyo's After Story.
- True Blue Femininity: Wears dark and light blue in Shin's and Ukyo's After Story, respectively.
Main Love Interests
Voiced by Tetsuya Kakihara (Japanese), Houston Hayes (English)
Shin is one of the heroine's childhood friends, and one year younger than her. He's studying for his college entrance exams and spends a lot of his time at cram school. Despite being rude and often harsh with his words, he always tries his best for the heroine.
In every route, except his own, he works as a chef at the Meido no Hitsuji café.
The heroine was injured in an accident on his route. She fell off a cliff in Shinano, and her injuries resulted in her memory-loss. Since the two were alone at the time of the accident, Shin gets suspected as having caused her injuries. Shin wants her to remember everything about the accident because it will prove his innoence, and the identity of the true culprit.
- All Girls Want Bad Boys: Subverted, as his appearance and mannerism leads many to believe this to be the basis for their relationship. However, Shin is not a bad boy, and kinder than he initially appears.
- Armor-Piercing Question: Downplayed early in his route, when he calmly asks the heroine why she hasn't called him by his name since yesterday, basically cornering her into admitting her amnesia.
- Brutal Honesty: Very blunt with his words.
- Childhood Friend Romance: He and the heroine are dating on his route.
- Clear My Name: The police suspected him of having purposefully injured the heroine, but everyone works together to prove his innocence, and that the heroine's fall was an accident. The original fall and tumble was an accident, but her further injuries were caused by Toma, who found and injured her in a fit of enraged jealousy.
- Color-Coded Characters: Red.
- Cruel to Be Kind: Sees no point in lying to spare anyone's feelings, when blunt and honest criticism could improve another person's abilities.
- Declaration of Protection: Gives one to the heroine in his route.
- Determinator: Spends majority of his route determined to help the heroine regain her memories and Toma's role in losing them to begin with.
- Disappeared Dad: His father got into a drunken brawl, and the guy he fought landed badly on the ground, resulting in his death. As such, Shin's father is in jail for involuntary manslaughter.
- Forceful Kiss: Gives several to the heroine in his route.
- Hidden Depths: Really enjoys studying and learning new things. He's also very observant of other people, and could tell instantly that the heroine's memories were gone.

- In the Hood: Wears a hooded jacket, though the hood is not up.
- Jerk with a Heart of Gold: As mean as he comes across, his heart is in the right place.
- Luminescent Blush: Sports one when the heroine does something he considers cute.
- Love Triangle: Type 4 on his route between him, the heroine, and Toma. Both of them have been in love with her for a long time, and Shin and the heroine started dating when he confessed to her. And Toma retained his unconfessed, unrequited feelings, and her choosing Shin over him leads to her almost getting killed at the lodge.
- Misunderstood Loner with a Heart of Gold: After his father was sent to prison, people believed that Shin was just as violent, and would turn out like him, so he was ignored by other children and treated like an outcast. This is among the reasons he cares so much for the heroine and Toma, as they stuck by his side regardless.
- Not So Different: Shin and Toma care deeply for the heroine and agree on the idea of being kind through harsh means, but often butt heads on how to do this. Shin seems cruel through his words, while Toma ends up cruel through his actions.
- Only Sane Man: Played for Drama, especially in Diamond World, where he rightfully points out how insane some of Toma's actions are. And compared to the other boyfriends, his personality and attitude come across as more stabil.
- Playing Card Motifs: Heart.
- The Rival: His relationship with Toma on their respective routes.
- Spotlight-Stealing Squad: Despite not being the True Route for Memories, Shin gets featured heavily and prominently on the series' covers and its merchandise. Reasons could be because his motif is Hearts, and that Ukyo is a secret character. However, the latter only applies to Memories.
- The Stoic: Downplayed, as Shin is on the reserved side of things, but still shows his emotions enough.
- Too Many Belts: Downplayed, with his default outfit◊ having him wear two belts as a choker, one belt-buckle on his jacket, and one belt that hangs unnecessarily from his hip.
- Tsundere Type A towards the heroine, though it's more teasing.
- Victorious Childhood Friend: While dating the heroine on his route.
- What Does She See in Him?: Several people wonder this in his route because of his harsh words towards the heroine, and her blasé attitude. And even the owner of the lodge admits that there was a rumor going on about a love triangle between them and Toma.
His After Story in Later revolves around his relationship with the heroine becoming stagnant. Shin knows how uncomfortable she is when he kisses her, and he admits to worrying that the heroine still thinks of him as nothing but a childhood friend. The heroine tells him that this isn't the case, but that she's too overcome with feelings when alone with him, and can't get herself to focus. Both agree to work harder on being open about their feelings.
- Anger Born of Worry: New World has him snap at the heroine for not telling him that she had injured her leg.
- Bridal Carry: One CG has him carry the heroine home this way because she had twisted her ankle.
- Childhood Marriage Promise: The heroine made one to him and Toma when they were young children, and Shin put a ring made out of a flower on her finger.
- He's All Grown Up: Played with, as the heroine has seen him grow up alongside her and never went through the shock phase. But a flashback has Shin admit that he wanted to be seen like this by her because he felt insecure about being younger and smaller than the heroine as children. He wanted to grow up and be strong enough to protect her, and wonders if he's managed that. This was the moment when the heroine stopped seeing Shin as just a childhood friend and saw him as a young man.
- I Want My Beloved to Be Happy: Willing to step back and leave the heroine be, until she stops seeing him as a childhood friend and is ready to have a romantic relationship with him. The heroine quickly tells him that it's not necessary.
- The Promise: Has a mock exam coming up and knows that he'll spend most of his time studying, so he can't meet the heroine for a while. But he promises that, if he manages to get an A on his exam, he'll take her on a date to the amusement park.
- Romantic Spoonfeeding: The heroine wants to do this to him on their date. Shin's horribly embarrassed about it, but reluctantly lets her feed him.

Ikki is 22 years old and a fourth-year university student.
He is polite and charming, which makes him popular. His popularity is especially big with women because of his eyes, to the point that he has a fanclub that meets him after work.
He works as a butler at the Meido no Hitsuji café in most routes.
His route has him and the others keep mentioning that his relationship with the heroine will be over when the end of August rolls around, leaving the heroine and Orion trying to figure out why this deadline has been set. They are also confused about Ikki acting oddly cold towards the heroine in public, while being very loving when they are alone.
- Ambiguously Human: A discussed trope early in his route, but ultimately averted; when speculating about Ikki's "condition" (his gaze), Orion claims he's never heard of a human having supernatural powers... though this is proven the case later on.
- Anger Born of Worry: Gets angry when the heroine waits in front of his house for him for hours, well until after it gets dark. He wonders if she has any idea how difficult this makes things because he's worried of what his fanclub will do to her if they see her there.
- Be Careful What You Wish For: Wished to be popular as a child because he was often ridiculed and mocked. He gained his hypnotic eyes, which caused every woman that looks him in the eyes to fall in love with him. It has made his life difficult when it comes to interacting with others.
- Blessed with Suck: His hypnotic gaze makes women fall in love with him easily, but he has a growing base of fangirls that rarely leaves him alone, and he reveals that it has also limited him in social aspects.
- The Casanova: Has had tons of relationships, none of them lasting longer than three months. He set that as a timelimit because of the amount of women who only liked him because of his eyes' powers, thinking that they'd grow tired of him by then. And unbeknowst to him, his fanclub enforces this three-month rule themselves when one of their own dates him, so that 'others can have their turn'.
- Chick Magnet: Any woman that has direct eye-contact with him falls in love with him.
- Chivalrous Pervert: Talks a big game around the heroine and has had an active history of romances, dropping some innuendos. But Ikki always respects the boundaries of the women he dates, never forcing them further than they feel comfortable with. According to Kent, part of this behavior comes from Ikki using physical affection as a substitute for romantic attraction.
- Color-Coded Characters: Blue.
- Cool Mask: Averted, as he wears a goofy mask when visiting a sick heroine.
- Cool Shades: Usually wears a lilac-tinted pair to keep more women from falling for him.
- Drowning My Sorrows: Tends to drink when he's having difficulty dealing with things.
- Facial Markings: Has a blue spade on his left cheekbone.
- Fashionable Asymmetry: His default attire◊ has him wear a pin-striped shirt and check-patterned pants, with one leg covered by his long boot.
- Forceful Kiss: Almost gives one to the heroine, but stops before their lips touch. And when she doesn't react or close her eyes, he backs off.
- Friends with Benefits: Implied to have had this relationship with some previous 'girlfriends'. One of his Bad Endings has him lie to the heroine, claiming that this was their relationship before she lost her memories.
- Get Out!: One of his Bad Endings has him tell the heroine to 'just go' when he realizes that their relationship is unsalvageable, and he has permanently lost her.
- Hair Decorations: Wears a spade-shaped hairclip with his regular outfit.
- Hands-On Approach: One CG has him do this, showing the heroine how to make a parfait.
- Hidden Depths: Despite his reputation as a playboy, Ikki is quite kind and considerate. He also enjoys math, often solving difficult math puzzles that Kent prepares for him. Also, he's studying to become an accountant.
- Hypnotic Eyes: Has a hypnotic gaze that causes any woman that looks at him to fall in love with him, and it's beyond his control. He wears sunglasses a lot to prevent more women from falling for him, but they have limited success.
- I Just Want to Be Loved: Sick and tired of the shallow affection from fangirls, Ikki's looking for someone to have a loving, long-lasting relationship with.
- I Just Want to Be Normal: Sees his hypnotic gaze as nothing but a burden anymore, knowing what it has cost him over the years. And he wants it gone, so he can have normal relationships with other people.
- I Love You Because I Can't Control You: Spade World had his initial interest in the heroine sparked because she appeared to be immune to his gaze, and didn't fall for him easily.
- Instant Fanclub: His fanclub accosts him after work and other times, making him late for dates.
- Lady Killer In Love: His route has him find honest love with the heroine.
- Long-Distance Relationship: His Normal Ending leaves his relationship with the heroine as this because she's moving back in with her father. Ikki leaves the continuation of the relationship up to the heroine, having already given up and thinking that the distance would sour things between them.
- Longing Look: Can be seen giving some to the heroine in public and when his fanclub is around. Best to not act on them, as it leads to a Bad Ending.
- Looking for Love in All the Wrong Places: Wants to find a meaningful, long-lasting relationship with someone, and has dated several of the girls in the fanclub. Worst place to look, as the fanclub keeps a close tally on the current girlfriend, demanding that she send daily reports on what they've done, and insists that the relationship doesn't exceed three months. Failing to comply to those rules, they turn nasty.
- Official Kiss: The last CG for his Good Ending shows Ikki having taken his sunglasses off and kissing the heroine in public. Both are things he has kept himself from doing, so it shows his determination to openly commit himself to his relationship with her and not letting his eyes be a problem for him anymore.
- Only Friend: To Kent. Downplayed with Kent to Ikki himself; while Ikki is clearly popular, Kent is the only close friend he has.
- Only Known by Their Nickname: His full name is Ikkyu, and Kent is the only one allowed to call him that.
- Odd Friendship: With Kent. Their friendship came into being because Kent was curious about Ikki's 'condition', which he claimed was the reason why Kent's girlfriend suddenly broke up with him by saying she fell in love with Ikki. Kent sees this in the past, and the two care about each other as friends do.
- Playing Card Motifs: Spade.
- Really Gets Around: By implication and reputation, but the three-months rule of his relationships means it's heavily downplayed.
- Secret Relationship: Downplayed in Spade World, as everyone knows that he and the heroine are dating. But Ikki tries to keep it a secret from the public how well their relationship is going, particularly from his fanclub.
- Sharp-Dressed Man: His default attire looks the closest, with its waistcoat and tie.
- So Beautiful, It's a Curse: Almost every woman that looks him in the eyes becomes smitten with him, and he feels it has isolated him from normal, friendly relationships. And his fanclub turns out to be a real threat to anyone they consider to be hogging Ikki's attention.
- The Social Expert: Enough that the heroine goes to him for love advice in Toma's route. He generally seems well aware of the implications of his actions, and cautious in his approach to women.
- Stood Up: Played with, as he isn't actually standing the heroine up. He's too busy paying attention to his fanclub and appeasing them, before picking her up and being sure that they will be left alone. This still leads to him being late by at least an hour.
- Technicolor Eyes: The anime increased the odd color-mixture in his eyes.
- Unable to Support a Wife: Spade World has the heroine's father against the idea of her moving in with Ikki or even room-sharing, citing this as one of the reasons.
- Unwanted Harem: Doesn't mind his fanclub, but has grown tired of them and wishes they'd leave him alone.
- Vitriolic Best Buds: Has a mild case with Kent.
- What Does She See in Him?: Orion wonders why the heroine was dating a playboy like Ikki. Especially when they learn that the heroine hates playboys, and admitted to not liking Ikki prior to her memory-loss.
- You Gotta Have Blue Hair: White with a blue shade.
His After Story in Later shows the heroine moving in with Ikki into his one-room apartment. The two work out how to live with each other now, though Ikki promises to not force the heroine into any intimate contact until she's ready for it. But outside of their personal matters, they also have to deal with her father continuing to reject her relationship and living with Ikki, and wanting to take her home. And even Ikki's old fanclub isn't ready to give up on him yet, much to the heroine's furstration and Ikki's annoyance.
- Cuddle Bug: Turns into a cuddler when intoxicated.
- Did They or Didn't They?: One CG has Ikki kiss the heroine while over her in bed and saying that he won't let her sleep, then the screen goes black. It's somewhat unclear if they were intimate. Both were dressed the next morning, although some of Ikki's later comments imply that they were.
- First-Name Basis: The heroine admits to feeling envious that Kent may call Ikki by his first name instead of a nickname, and Ikki allows her to call him by his first name once. Since she adds -san to his first name, he ends up laughing at the sound of it and says that maybe he'll let her try again some other time.
- Insistent Terminology: The heroine reminds Ikki that they are not cohabiting, but merely room-sharing, which Ikki immediately points out to be practically the same to him. It's not brought up again.
- Lap Pillow: One CG has him lay his head on the heroine's lap.
- Lethal Chef: Downplayed, as his cooking isn't lethal. His own stance on his cooking is 'as long as it's edible'. Justified, as the heroine thinks that, since girls kept cooking for him and giving him homecooked food as gifts, Ikki simply never had a reason to really learn or get good at it.
- Make a Wish: Sees a shooting star at his wedding to the heroine. He wishes that he'll be able to stay with her until death parts them, while she wishes that his eyes return to normal and they can have a peaceful life together. When Ikki tells her that he isn't concerned about his eyes or their power anymore, she gets embarrassed and promises to wish for the same thing as he did next time.
- Megane: Admits to wearing glasses during university classes because it makes reading easier. He doesn't wear them at home because he thinks they don't suit him. The heroine disagrees.
- Must Have Caffeine: Requires coffee to fully wake up for the day.
- My Greatest Failure: Still feels horrible for making the heroine feel alone and not someone she could confide in when she had amnesia, though she points out that it's not his fault.
- My Own Private "I Do": Marries the heroine in a private ceremony at night that's just the two of them.
- Not a Morning Person: Has difficulty getting up in the morning. He even manages to fall asleep while in the middle of getting dressed, which the heroine finds out the hard way.
- Sentimental Drunk: Becomes very open about how much he loves the heroine and laments just how adorable she is to Kent while drunk.
- Time Skip: The end of his After Story takes place at least three years later, as he planned to marry the heroine when she graduates from university, and she was a first-year student.
- Wholesome Crossdresser: Wore a dress and long-haired wig for his highschool festival when his class was running a café. His special CG shows him to have not been happy about his getup.
Voiced by Akira Ishida (Japanese), Tyler Galindo (English)
Kent is 25 years old and a graduate student of mathematics. He enjoys math and often creates mathematical puzzles and quizzes for others to solve in his spare time. Kent believes that everything in life can be approached through logic and reason, leading to his behavior and words often being blunt.
He works as a chef at the Meido no Hitsuji café in Joker World.
His route makes it clear that he and the heroine had a big fight a few days prior, leaving his interactions with her to be even more harsh than usually. Kent misinterprets the heroine's unusual demeanor to be an attempt to patch things up between them, and he works on approaching her more openly than before himself. Even as he's busy preparing for his presentation to get a study abroad.
- Adorkable: Comes across as stiff and cold towards the heroine, but this comes from an inexperience of romantic relationships. And he admits to wanting to spend a lot of time with the heroine, even if that time is spent working silently on separate things.
- Affectionate Gesture to the Head: One CG has him ruffle the heroine's hair, albeit rather roughly.
- Affectionate Nickname: Called 'Ken' by Ikki.
- Ambiguous Disorder: His utter lack of social skills seems to indicate this. Looking at his parents, and their ultra-rational worldview, it appears to be genetic.
- Armor-Piercing Question: One flashback shows Kent being very blunt and coming across as rude to the heroine with his words, and she slaps him. Kent asks what her reason is for him deserving to be slapped, and what she has accomplished by doing it. The heroine cannot give an adequate answer.
- Awkward Kiss: Downplayed, as the kiss isn't awkward, but the preparation is. Kent misunderstands the heroine looking in his direction for a long while as a 'hot look', and asks if they should kiss. When they do kiss, both are nervous and end up knocking foreheads together. But they do manage to kiss and look happily embarrassed about it.
- Belligerent Sexual Tension: Deconstructed, as his relationship with the heroine was this before she lost her memories, and it was clear that they were unhappy. Kent's analytical approach to emotional matters and the heroine's reluctance to be open about her feelings caused them to be incapable of having a conversation that didn't devolve into arguing with each other. It isn't until the heroine loses her memories, and has no inhibition to keep her feelings contained, that the two become able to actually communicate with each other.
- The Big Guy: The tallest of the love interests.
- Britain is Only London: His study abroad will send him to London.
- Brutal Honesty: Even more blunt than Shin, as anything else would be inefficient.
- Color-Coded Characters: Green.
- Demoted to Extra: The anime gave Kent's route only one episode. The others got two, at least.
- Friend or Idol Decision: On the day of his presentation, the heroine gets into an accident and taken to the hospital. When Ikki informs Kent of this, Kent points this dilemma out. His decision is based on what Ending the player is currently heading for.
- Hot for Teacher: Tutored the heroine's math study club, where she initially fell for him.
- Huge Guy, Tiny Girl: Has to bow down to kiss the heroine.
- It's All My Fault: His Good Ending has him admit that he felt something akin to jealousy towards the heroine's dog and wanted it to disappear. Shortly after, Kuro got loose, was hit by a car, and died from the resulting injuries. Despite knowing that it was an accident, and his guilt was irrational, it's been burdening him.
- I Kiss Your Hand: One CG has him kiss the heroine's hand as part of his informal proposal.
- Lack of Empathy: Doesn't exactly lack empathy, but his rational outlook on life clashes with emotional matters, and he comes across as this. This is why the heroine, still emotionally reeling from her dog's death, told Kent that she hated him. His route involves growing out of his extreme views and considering the emotional side of things.
- Megane: The only bespectacled love interest.
- No Social Skills: Has difficulty talking normally with people because he's always thinking with cold logic.
- Odd Friendship: With Ikki. Both turn out to rather enjoy solving mathematical equations, and the two can be honest with each other, without their respective oddities being much of a deal.
- Playing Card Motifs: Clover.
- Shared Family Quirks: His parents are even more rational about things in life than Kent.
- Smart People Wear Glasses: Was the tutor of the heroine's math study club.
- The Spock: Everything he does is done with an extremely logical approach, which leads to others distancing themselves from him. He's more concerned with logic than emotion, though his route has him work on letting more of his feelings show through.
- The Stoic: His facial expressions are subdued.
- Time Skip: His Good Ending skips ahead to the next year's winter, showing him and the heroine in London.
- Too Many Belts: His default outfit◊ has belts down his left coatside, his entire left sleeve, one green belt on his right arm, and some green cross-belts on his right side.
- Vitriolic Best Buds: Has a mild version of this with Ikki.
- What Does She See in Him?: Orion wonders not only why the heroine and Kent are dating, but how these two even ended up starting a relationship. Kent rarely talks, his text messages are super short, and feeling like an obligation, and his way of talking can be quite belligerent.
- You No Take Candle: His Good Ending has him meet up with the heroine and saying 'I'm sorry for waiting' in English. What he actually meant to say was 'I'm sorry for making you wait', since he's the one to arrive as second. The English translation fixed this mistake in the text.
His After Story in Later fills in what happens between the moment Kent plans to do his study abroad with the heroine next year and his Good Ending having the two of them being in London together. The heroine is studying hard to improve her grades and English, so that she'll be accepted as an exchange student by the next year. And Kent gets confronted with the fact that he knows nothing about typical household chores, and asks the heroine to teach him basic skills like cooking and cleaning.
- Amazingly Embarrassing Parents: Considers his parents to be this, mostly because they freely talk about his relationship with the heroine. And they make no secret of the fact that they consider her their daughter-in-law, even with Kent telling them to hold their horses, those two are not deterred.
- Call-Back: His Good Ending in Memories showed him with the heroine in London, wearing a green, striped scarf. Said scarf turns out to be a birthday gift the heroine gives him in his After Story.
- Forgets to Eat: Admits to sometimes getting so focused on his university work that he forgets to take care of basic needs, like eating and drinking.
- Forgotten Birthday: Doesn't care much for birthdays, and doesn't realize the heroine is planning a surprise party when she asks him to meet him at her home for the 23rd.
- Men Can't Keep House: Housekeeping chores are not his thing. He has no knowledge of how to do it, and his parents recall a time where he tried to wash the entire futon when the cover got dirty. Part of his After Story involves him learning how to keep house.
- Moment Killer: When the heroine and he are about to have their second kiss, the timer goes off and interrupts them, reminding them of the meat cooking. They try again later, and Kent's cellphone rings at the last moment.
- Real Men Wear Pink: Despite still learning it, Kent picks up on things like doing laundry fast, and gains a passion for cooking and baking. When he cooks alongside the heroine, he also dons a pink apron.
- Time Skip: The end of his After Story skips to around the same time as his Good Ending in Memories did, depicting him and the heroine walking around London together.
- Twinkle in the Eye: One CG has him sporting one while cooking, though it comes across as funny because of the pink apron he's wearing.
- Wacky Marriage Proposal: Downplayed, when the heroine looks through his recipe notebook and comes across the page where Kent wrote down tips on how to set the mood and proceed with a marriage proposal. Kent laments that he told her to not read that page, but goes along with it and just proposes then and there.

Toma is another childhood friend of the heroine's and a year older than her. He cares deeply for the heroine, and wants nothing more than to protect her from harm. He's a second-year law student at Myouga University.
In Heart, Clover, and Joker World, he works as a butler at the Meido no Hitsuji café.
His route has him be aware of the heroine's memory-loss because he found her on the ground in front of her home. When he learns that she's being harassed by someone anonymous at her place, Toma offers her to stay at his place for a while. When Shin learns that Toma is keeping the heroine around, he reveals that they have no romantic relationship, contrary to what Toma originally told her. Things get worse when Toma reveals the extent he's willing to go to keep the heroine safe.
- Anger Born of Worry: Gets angry with the heroine for leaving his place without telling him, since the whole point of having her at his place was to keep her safe from the harassment at her home.
- Attempted Rape: Near the end of his route, it's clear that he's threatening to rape the heroine because she got out of the cage. Something will occur to stop him, though what this is depends on the Ending.
- Beware the Nice Ones: Comes across as genuinely sweet, and as a kind, brotherly type of person. He cares for the heroine and Shin, seeing them not only as his childhood friends, but also younger siblings that he needs to take care of. But Shin's route reveals that his kind demeanor belies how bad he is with rejection. And his own route increases this by proving how far his protective streak goes, and that he has some problem restraining his desire of wanting to keep the heroine for himself and protecting her from harm.
- Big Brother Mentor: Has this attitude towards Shin and the heroine.
- Childhood Friend Romance: Heart and Diamond World have him hold a torch for the heroine.
- Color-Coded Characters: Yellow.
- Crazy Jealous Guy: Shin's route reveals him to have these aspects. His anger and hurt feelings at the heroine choosing Shin over him, and that she mistook him for Shin when he found her injured at the base of the cliff, caused him to lash out.
- Cruel to Be Kind: Wants to keep the heroine safe, but goes about it the wrong way. He lies to her, drugs her food and drink to keep her at his house, and proceeds to isolate her from everyone by taking her cellphone away. To top things off, he eventually locks her into a cage.

- Creepy Shadowed Undereyes: Sports them when truly angered. And his yandere side triggered.

- Fashionable Asymmetry: His default outfit◊ has him wear a longsleeved shirt that has an orange-black stripe pattern, with the left sleeve being all black and longer, ending in tatters.
- Gilded Cage: Believes the cage he puts the heroine into as this. It's large enough for her to stretch, fills it with plush toys and similar to keep her entertained and comfortable, and brings her food. He also lets her go to the bathroom and wash herself, as long as he has a hold on the leash attached to her.
- Hair Decorations: Wears a black headband with a golden diamond pattern on it.
- Hair of Gold, Heart of Gold: Averted, as looking below Toma's initial, sweet personality will reveal his personal issues, and what he's really like.
- Heroic Self-Deprecation: Shows signs of this on his route. Claims to be the worst, and having no redeeming qualities beyond his good looks. This is also why he believes the heroine would never fall in love with him.
- Hidden Depths: Proves to have a very dark side to his sunny disposition. On a more mundane side, he's studying to become a prosecutor.

- Karma Houdini
- Averted for Shin's Good Ending. Toma turns himself in to the police for injuring the heroine.

- The Kindnapper: Keeps the heroine prisoner at his home, deciding it's the only way to properly protect her.
- Lying to Protect Your Feelings: Where he differs from Shin, who prefers brutal honesty. Toma will always lie to spare the heroine's feelings and make her happy.
- Mask of Sanity: Every route portrays Toma as very kind and stable, and helpful to everyone. The end of Shin's route and his own route have him show his true face, indicating that he's really good at hiding his instability. There is one Bad Ending in Ukyo's route where Toma slips up.
- Motor Mouth: Spade World has him fall into this when explaining to Ikki and Kent how exactly he and the heroine are related, stating that one of their parents married the other's parent, before getting divorced again and remarrying others. He talks so fast that Ikki can't keep up, and Kent offers to explain it in slower, simpler terms.
- Nice Guy: Played with, as Toma generally gets portrayed as a kind and helpful type, but his own route and the end of Shin's proves him to be not quite so nice.
- Not Blood Siblings: Spade World has him call himself the heroine's older brother, but points out that there's no blood relation. The two are former stepsiblings, but kept seeing each other as siblings.

- The Rival: Considers Shin his rival, especially in Heart World.
- Romantic FakeReal Turn: Played with, as both parties were in love with each other, but not aware of it. When she regains a fragment of a memory, the heroine asks Toma if the two of them were dating before she gained amnesia. Toma says they were, but kept quiet to not stress her about it. They were not actually dating, as Shin reveals partway through his route.
- Saying Too Much: Heart World has him ask the heroine if her head hurts when seeing her. Shin points out that most people would ask about her bandaged neck, and not about her uninjured head. This was his first clue that Toma was the one to worsen the heroine's injuries.
- She's Not My Girlfriend: A nurse believes Toma to be the heroine's boyfriend when he takes her to the hospital, but he calmly corrects the misunderstanding.
- Stepford Smiler: Has elements of this, being typically cheerful and kind. There are moments where his smile slips, and his behavior switches to the other side.
- Well-Intentioned Extremist: In his mind, his actions were justified for keeping the heroine safe.
- What Does She See in Him?: Orion cannot understand why the heroine loves Toma, considering he has locked her into a cage and has been drugging her for the past few days.
- What the Hell, Hero?: His route has Shin ask Toma what he's playing at, claiming to keep the heroine at his home to keep the heroine safe from the harassment of Ikki's fangirls, when the two of them aren't even dating. His Normal Ending has him getting called out by Shin again, albeit off-screen.
- Yandere: Towards the heroine.
His After Story in Later revolves around the aftermath of his actions and the bullying of the fangirls. He asks the heroine to keep staying at his place for at least a week, until things on the internet have calmed down. However, he's hesitant to really proceed with a romantic relationship with the heroine, saying that, even if the heroine has forgiven him, he thinks that he shouldn't be allowed to get away without punishment.
- Call-Back: The entire event of him being dragged into a lingerie store gets repeated in his After Story. Even with the same employee tending to them, despite being in a different store location.
- Crazy-Prepared: Admits to having been like this when he thought the heroine was in danger. When she mentions that she hasn't seen him in his pajamas before, he mentions that he didn't change out of his regular clothes because he wanted to be able to leave with the heroine the second it seemed like his place was no longer safe from Ikki's fangirls.
- Fourth Date Marriage: Played with, as he and the heroine have known each other since childhood. But his After Story has him and the heroine start dating, and then proceed to get engaged a mere four days later.
- The Ghost: Mentioned in Shin's After Story, but doesn't physically appear.
- I Want My Beloved to Be Happy: Admits how far he was ready to go for this. He figured that he and the heroine might grow apart as they got older, and she'd eventually fall in love with someone else, and he was willing to let her go. He even refers to how he planned to 'return her to Ikki' in Memories, when he thought she was dating him.
- Karma Houdini: His After Story has him insist on averting this, wanting to get punished for what he did.
- Stalker Shrine: Has an album full of photos of the heroine, though he insists that they are not stalker images that were taken in secret. Their university displays pictures taken on field trips and similar, and students could buy copies of pictures they wanted.
- Walking the Earth: Implied to be doing this in Shin's After Story, as Toma was not prosecuted for injuring the heroine. Since she refused to press charges, Toma chose to stay away from them for some time. The heroine and Shin note that they do hope he'll eventually come back.

Ukyo is 24 years old and a freelance photographer. He has travelled the world and lived in various countries, first because of his family life and eventually because of his job. He's polite and friendly, but can easily come across as creepy and threatening to the heroine, much to her confusion and terror. He seems to know the heroine in every route.
His route has the heroine meet him at the beginning of August and being confused, as Ukyo seems to know her, but he won't explain how. Despite the heroine trying to talk to Ukyo, he keeps insisting that he must stay away from her, but also find himself repeatedly wanting to be with her. He also warns her of instances that could prove fatal to her, and claims that he will explain things at a later date.

- Be Careful What You Wish For: Ukyo begged Lord Nhil to save the heroine from death and allow for him to be with her again, even at the cost of her not remembering him. Lord Nhil rewound time, and let Ukyo travel to other timelines to see the living heroine, but even if Ukyo chooses to let the heroine be happy with another man, his wish cannot be fulfilled completely. And since his and the heroine's simultaneous existence are considered a universal anomaly, one of them has to die by the end of August.
- Big Damn Heroes: Joker World has him save the heroine from potentially fatal accidents multiple times. The biggest is when she gets locked into a shrine by Ikki's jealous fangirls, who accidentally set it on fire. Ukyo sees her inside and bursts down the door, saving her.
- Camera Fiend: Subverted, as he's mostly a landscape photographer. Though he took a beautiful picture of the heroine while they were dating.
- Color-Coded Characters: Purple.
- Creepy Shadowed Undereyes: The other Ukyo sports them.

- Despair Event Horizon: Pushed past it after having experienced the heroine's and his own death for an unknown amount of time.
- Driven to Suicide: The path to his Good Ending has Ukyo overpower his other side, who is about to kill the heroine, and stabs himself in the chest to save her. Despite knowing that this is his last jump and chance to be with the heroine.

- Groundhog Peggy Sue: Lord Nhil allows Ukyo to go through several timelines over and over, until Ukyo's entire wish is fulfilled. Only then will Lord Nhil regain his full powers.
- Guide Dang It!: Every route can lead to the player locking themselves out from the Good Ending because of mistakes, but Ukyo's route is worse. Making mistakes on his route can lead to the player obtaining nothing but Bad Endings, with the path for his Normal and Good Ending being incredibly precise.
- I Want My Beloved to Be Happy: Willing to step aside in other routes and let the heroine be happy with another man. Even if this means that Ukyo will have to die at the end of August.
- Jekyll & Hyde: Acts sweet, kind, and polite, but switches easily to be murderous and threatening. His other personality came from having gone through multiple timelines, and having seen the heroine die very often, either through his own hands or other means, or having to die himself to keep her alive. Ukyo loves the heroine, while his other personality wants to kill her for his own survival.
- Knife Nut: Commonly seen using a knife when trying to kill the heroine.
- Long-Haired Pretty Boy: Has the longest hair out of the love interests.

- Slasher Smile: The other Ukyo's default expression.
- Star-Crossed Lovers: With the heroine. One of them is fated to die at the end of August, as their existence in the same timeline is considered a universal anomaly, since the heroine was supposed to die from the injuries sustained in the university's fire. His Good Ending averts this fate.
- Vague Age: Official material◊ lists his age as '24?'. Despite having died multiple times, Ukyo kept living again and travelling to other timelines. He even admits that he's actually had a very long life.
- Walking Spoiler: Not only is Ukyo a Secret Character, but also the reason for her amnesia.
- You Are Worth Hell: Goes through multiple timelines to make sure the heroine survives, even if this means he has to die in her stead.
- You Gotta Have Blue Hair: Light-green.
His After Story in Later has him and the heroine live rather happily, with neither of them being considered an anomaly to the universe anymore. However, the heroine cannot remember the events of August 25th, which leads to confusion when the day is mentioned. And Ukyo is trying to shield her from remembering anything unpleasant.
- Amnesiac Dissonance: One Ukyo isn't aware what is going on when the other Ukyo is in control. This leads to the one taking over to find himself in a place he has no knowledge of having gone to, and not knowing what was going on. As such, they choose to write notes to each other, saying what has been going on, and keeping a form of contact between the two.
- Bridal Carry: His first and last two CGs have him do this to the heroine. The first has him carrying her out of the burning university. The last two are him carrying her away from the others during the café wedding photoshoot.
- Covert Pervert: Played with, as he has no problems admitting to wanting to hug and kiss the heroine, and pulling her to the ground, though he knows that it's not acceptable public behavior in Japan. Much to her surprise and embarrassment, she reminds him that it isn't acceptable public behavior in most of the world.
- Dude Looks Like a Lady: Admits to people having often mistaken him for a girl in school because of his long hair and slim build, which is why he was part of 'girls' sportsclubs' several times in school.
- Heroic Self-Deprecation: Pulls himself through the mud when pointing out that he isn't sure why the heroine stays with him, citing his being an idiot, and airhead, even going further by mocking his long hair, having no friends, comparing himself to a girl, a phantom, and death, and he also sucks as a self-styled photographer. The heroine tells him that all of those are things she loves about him.
- Iron Stomach: Type one. The guys mess with his food by putting a lot of habanero sauce over his pasta dish, and are amazed when Ukyo also puts tabasco sauce on top, without even mentioning a difference in taste.
- Japanese Honorifics: Ukyo uses Ore (俺), while the other Ukyo uses Ore (オレ).
- Japanese School Club: Has participated in almost every club various schools have offered, partly because of his frequent changing of schools and partly because of his inability to say no to others. This includes having done things such as cheerleading, lacrosse, hula, basketball, soccer, taking part in the debate club, cooking club, etc...
- Mistaken for Cheating: The heroine finds notes in his room that make it appear like Ukyo is living with another person, and she's worried that it might be another woman. Ukyo tells her that it isn't the case, but how he converses with his split personality.
- Real Men Wear Pink: The other Ukyo does a lot of the housework because he considers Ukyo to have become very lax about it. Ukyo's Special CG also shows the other Ukyo hanging up the laundry with a scowl, wearing a frilly apron.

Orion is a spirit from the dream world.
While out in the human world, he accidentally ended up merging with the heroine's soul and ended up pushing her memories out of her, resulting in her amnesia.
Orion can only be seen and heard by the heroine. As his merging with her made her lose her memories, he feels guilty over this and vows to help her regain them.
- Ascended Extra: LATER gave him his own route.

- Horned Humanoid: Two black horns with two yellow rings at their base.
- Humanity Ensues: Ukyo's Good Ending has him get reincarnated into a human, alongside Lord Nhil.
- Mission from God: Turns out that his meeting and crashing into the heroine was not an accident. He was sent out to the human world to try and find his creator and leader of the spirits, Lord Nhil. Orion being pulled towards the heroine has to do with her being the source of the anomaly, and Nhil being close-by in the body of Ukyo.
- Mystical White Hair: Orion's hair is a shade of gray with hints of white, serving to underline his being a spirit. The anime darkened his hair to being a darker shade of gray.
- Non-Human Sidekick: No matter how human he might look, Orion is a spirit from the dream world.
- Spirit Advisor: Can only be heard and seen by the heroine, and Orion often talks with her about ideas on what might help her trigger any memories.
- Synchronization: Due to having merged with the heroine's soul, Orion can tell her emotional and physical state, even getting tired when she does. However, Orion quickly points out that he can severe this 'link' for some time, so there is no embarrassment or awkwardness when things get romantic with one of the boyfriends.
- Voice for the Voiceless: In Clover World, Orion knows he can't talk to other humans, and requires the heroine's help to talk to Kent. He asks her to write down what he says, so that he, the heroine and Kent can have a three-way conversation about her lack of memories.
The heroine's best friend.
Sawa is a lively university student and studies at the same school as the heroine and Mine. Some routes have her work as a maid at the Meido no Hitsuji café.
- Ambiguously Gay: The anime made her come across as this. Sawa visits the café in a timeline when she doesn't actually work there, just so she can flirt a little with the heroine, and looks a little betrayed to learn that the heroine likes Ikki. Sawa even has subtle moments where she seems to be trying to steer the heroine's interest away from him. She's also really happy about the high female-to-male ratio on one of the trips. Some viewers that never played the games thought she might have been a gay option.

- O.O.C. Is Serious Business: Sawa seems unusually serious and quiet before the heroine heads to bed in one of the routes. The heroine is confused about this, but thinks little of it.

- Passionate Sports Girl: She's a member in several sports clubs.
- Tomboy and Girly Girl: Sawa is the tomboy to Mine's girly girl.
- Tomboyish Ponytail: Her messy ponytail adds to her tomboyish nature.
Mine is a co-worker of the heroine's.

- Curtains Match the Windows: Pink hair and pink eyes.

- Long Hair Is Feminine: Out of the three female employees of the café, Mine is the most feminine.

- Pretty Butterflies: Mine has a butterfly-theme in her design. Not only does she wear a butterfly hairclip, her purple undershirt has a butterfly instead of a ribbon, and her left tight has a row of butterflies on it. This is indicative on how she appears as a very cute girl on first sight, but her personality always has shades of mischief behind it. And she can come across as rather teasingly-nasty to the heroine in certain routes.
- Relationship Sabotage: Tries to pull this in Clover World a few times. It doesn't work because Mine mistakenly believes that the heroine is dating the manager of the café, on whom Mine has a crush in the route. When the misunderstanding is cleared up, she feels pretty stupid for having done those things.
- Rose-Haired Sweetie: She's sweet and kindhearted in some routes. In other routes, she's more cold towards the heroine because she considers her a rival in love, but still has her well-being at heart.

- Tomboy and Girly Girl: Mine is the girly girl to Sawa's tomboy.
- Valley Girl: The English dub has her talk like this.
- What Does She See in Him?: Played with, as Clover World has her ask the heroine why she likes her boyfriend so much. Mine points out that the guy's so difficult to understand because his communication is so weird, and his stoicness can be frustrating... but makes it sound positive. Mine is actually talking about the manager and not about Kent, though the two have similar personalities in that route.

The manager of the Meido no Hitsuji café.His personality is completely different for each route.

- Multiple-Choice Past: His past is implied to be different in each world. Heart World has him trained in song and dance, while Spade World gives him the past of a war general. Joker World implies that he used to be an assassin.
- Mysterious Past: His past is never revealed, but does mention being on 'the battlefield' a few times. Orion wonders in more than one route if Waka is a former freelance mercenary.
- The Quiet One: His personality for Clover World, where Waka mostly communicates through looks and altering facial expressions. It's actually a talent of his employees in that route to read his expressions and knowing what he's 'saying'.
- Reasonable Authority Figure: His personality for Diamond World, with him caring for his employees' well-beings, and gladly giving the heroine time off because she's not feeling well. Though this is a lie told by Touma, who has been keeping her at his house, before imprisoning her.
- Stealth Hi/Bye: Pulls this off in Clover World, where he appears instantly near an employee.
- Troll: His personality in Joker World, making up an elaborate sob-story about why he's subscribed to a magazine.
The leader of Ikki's fanclub.Rika is a sarcastic and aristocratic woman, and her obsessive love for Ikki tends to put her at odds with the heroine. She's very loving towards Ikki, but also keeps a rein on the other fangirls, particularly the new members.
- Adaptation Dye-Job: Her hair is a much paler blonde with a hint of green in it. The anime altered this to a more typical, brighter blonde.
- Alpha Bitch: Plays this role in most routes, where she's the woman in charge of Ikki's fanclub and believes this to make her better than the heroine. Spade World has Ikki's fanclub being an actual threat to the heroine because of her relationship with Ikki, making Rika the de-facto antagonist of that route.
- Curtains Match the Window: Blonde hair and golden eyes.
- Hair Decorations: Can be difficult to see, but she wears a black hairband under her hat and a black ribbon, with its ends falling over her forehead.
- Lovable Alpha Bitch: She's one in Joker World and kinder towards the heroine because she's actually friends with her.
- Murder the Hypotenuse: Threatens this to the heroine in routes where she believes her to be stealing Ikki's attention away from Rika and his fanclub. Particularly in Spade World, where the fanclub becomes insanely jealous about her relationship with Ikki. More than one Bad Ending has her and the fanclub succeed in getting the heroine out of the way, though none of them actually kill her.
- Nice Hat: Wears a giant, elaborate flat hat with black-and-pink stripes except for a small crown near the center of the headgear. Next to the crown is a white fur-like pelt that falls over the rim.
- Ojou: Heavily implied to be one.
- Slasher Smile: Sports one when she's threatening the heroine with death.

The heroine's father. Very little is known about him, as he never makes a physical appearance in any of the routes, except for Spade World and in Ikki's After Story. This leads to his appearance in Spade World to be the one with the most personality. Most routes do imply that he works overseas.
- The Casanova: Used to date a lot of women in his youth, before growing tired of them and ending the relationship, often starting up a new one shortly after. He has also been married four times so far, though he seems to have given up on his casanova ways.
- Character Development: The end of Ikki's After Story has him see how earnest Ikki and the heroine are about each other, and he thinks about re-evaluating his relationship with his wife and treating her better.
- Daddy's Girl: Implies that his daughter was one when she was younger, having clung to his arm and begging him to not go out with women and instead spend time with her.
- Dating What Daddy Hates: Dislikes his daughter dating and living with Ikki, since he believes he knows that Ikki will grow tired of her and eventually dump her for someone else. Comes around in Later, when Ikki proves how far he's planned his life with the heroine.
- Everyone Calls Him "Barkeep": Only referred to as 'Father'.
- Generic Guy: Outside of Spade World, very little is known about him. He either works overseas or in a job that requires a lot of business trips.
- The Ghost: Doesn't make a physical appearance in any route other than Spade World.
- No Name Given: Has not been given a name.
- Parents as People: He's fully aware that his daughter is a legal adult, but that her young age has him worry that she'll end up getting hurt by her decisions and not having thought of problems in the long-term.
- Parent with New Paramour: Spade World has him have remarried for a third time, though the heroine hasn't met her current stepmother. It's not mentioned how well the heroine got along with the previous stepmothers or this one.
- Sharp-Dressed Man: Always wears a suit and tie.
- When You Coming Home, Dad?: The heroine mentions in Ikki's After Story that he was often away on dates with women, leaving her to learn to care for herself from an early age onward.
- You Remind Me of X: Ikki reminds him of himself as a youth, since he was a playboy, too. This is among the reasons he's against his daughter dating Ikki.
Nhil is the leader of the spirits and Orion's master. Very little is known about him, though Orion reveals that he has gone missing for some time. This also reveals the reason why Orion was in the human world to begin with, having gone there to try and find Nhil.
Nhil turns out to be possessing Ukyo, similar to Orion having possessed the heroine. When Ukyo begged Nhil to save the heroine from her fated death, he used his powers to let Ukyo travel to various worlds in the hope of fulfilling his wish.
With Ukyo repeatedly dying or seeing the heroine die, Nhil eventually realized that the universe itself was trying to balance out the anomaly that was Ukyo's and the heroine's continued existences in the same world.
Nhil's powers weakened over the many attempts at fulfilling Ukyo's wish and failing, leaving him with very little left. With the last of his powers, he went to the original Joker World and rewound time, with him and Ukyo knowing that this was the last chance they had.
- God Needs Prayers Badly: His powers are sustained by fulfilling wishes. When his powers were waning, he tried to find a human with a wish strong enough that would reinvigorate his powers and found Ukyo.
- Greater-Scope Villain: Played with, as Nhil isn't evil. He meant well by trying to fulfill Ukyo's wish, but his help and the resulting failures led to Ukyo's split-personality and fighting over whether he wanted the heroine to die or to survive.
- Horned Humanoid: Just like Orion, he has black horns with two yellow rings at their base.
- Humanity Ensues: In Ukyo's Good Ending, Nhil and Orion are subjected to 'punishment' for their intervening into the human world. Their punishment involves being reincarnated into humans.
- Intrigued by Humanity: He's very interested in humans, wanting to know what they are like and how they think.
- Mystical White Hair: His hair is the same white-ish shade as Orion's.
- Time Master: As a god, Nhil has the power to rewind time.
