Takumi/Ami Aiba

https://static.tvtropes.org/pmwiki/pub/images/digimon_cs_aiba.png
Takumi (left), Ami (right)
Voiced by: Yoshitsugu Matsuoka (Takumi), Rumi Ookubo (Ami)

The protagonist, whose first name and gender can be set by the player. A member of "Enjoy Chat" and a user of EDEN, who, after being mysteriously given the "Digimon Capture" that allows them to scan and collect Digimon, gets into an accident with an Eater and becomes a half-digital entity in the process. They're eventually found by Kyoko, who takes them into her service as her assistant so that they can recover their body and discover the secrets behind Eater and EDEN. They have the special ability to "jump" into digital fields and networks in order to travel between and into different areas that would normally be impossible for someone with a physical body, which is referred to in universe as a "Connection Jump".

Although in-game their personality is up to the player's interpretation as they're a Heroic Mime, reactions to their behavior, along with their sprites and dialogue choices, indicate them to be a friendly, outgoing, helpful, and sociable person.

The player is given the choice between Terriermon, Palmon, and Hagurumon as a starter, although ultimately they can have any Digimon available in the game. In the Master Cup, their Mirror Match counterpart uses the evolved forms of the three starters which they are commonly associated with: MegaGargomon, Rosemon and HiAndromon.


  • All-Loving Hero: Their sole dialogue choice when confronted by Suedou about why they would want to save him after everything he did is simply that they don't want anyone to disappear, and indeed up until then they'd been stubbornly insisting on getting Yuuko and Arata out of Eater even despite their protests. There are also multiple points in the game where, after you're given fairly idealistic dialogue choices, other characters will respond that it's something they would say.
    • If a Digimon asks on DigiLine what they like, their response will simply be that they like so many things that they couldn't possibly list them all.
  • Amateur Sleuth: Gets hired by Kyoko, a professional detective, to be her assistant despite having no experience or education in the field whatsoever. Granted, circumstances dictate that they're more like engaging in less-than-legal stuff on her behalf and aren't on the official record as working under her as long as their body is in the hospital, but that doesn't explain the large amount of miscellaneous requests they carry on her behalf (that she accepts money for!).
  • Ambiguously Gay: The female protagonist, due to some writing mishaps in which lines blatantly written for the male character (such as hitting on girls in the story) are left untouched for the female. This effect goes both ways as Arata still seems to want to make himself appear "mysterious and cool" for you if you are a male player too when you chose to play along with it.
  • Big Brother Instinct: There's an end-game quest where the protagonist befriends a little girl, who he was supposed to be protecting from Digimon, who turned out to be her friends. When he took a longer-then-expected nap and missed their meet up time, he ran across a good chunk of Tokyo in just a few minutes to protect her from a violent Digimon.
  • Bunny-Ears Lawyer: An upbeat, cheerful teenager doesn't seem like they'd make an effective detective but their impeccable track record would say otherwise.
  • Cast from Hit Points: Connect Jumping into Eater starts to take a toll on their body, to the point where it finally deteriorates from overusing it.
  • Chekhov's Skill: Connect Jumping into Eater to save people trapped in it sure comes in helpful later.
  • Chick Magnet: Yuuko starts to behave in a very Tsundere-like way in the second half of the game after you save her from Eater, Nokia expresses jealousy over the idea of the protagonist being into someone other than her. Rina is fond of them, Sayo and Makiko are Tsundere with them. Mirei employs her usual behavior towards them, Then there's Kyokonot to mention Alphamon.It's even taken to more ridiculous levels when both Rie and Fie flirt with them at some point. By the end of the game, they effectively end up surrounded by a ton of girls who at the very least are quite fond of them and Arata.
  • Crazy Enough to Work: "Eaters are digital entities, so..."
  • Crouching Moron, Hidden Badass: They can be rather goofy, jovial and sometimes come off as not being very bright, but they're still extremely competent at what they do. Able to match and defeat members of the Royal Knights one by one is certainty no easy feat.
  • Cursed with Awesome: Sure, they're separated from a physical body, but it gives them the ability to jump into computers and travel through networks. Kyoko even considers it a blessing to her investigations. The "cursed" part only comes in as it becomes apparent that being half-digital makes them susceptible to network disturbances, and overusing Connection Jump will cause them to disintegrate entirely.
  • Dangerously Short Skirt: The female protagonist's skirt leaves little to the imagination.
  • Disappeared Dad: If a Digimon asks on DigiLine about their family, their response will be that it's only them and their mom, with no father mentioned. The localization translates one of Kyoko's lines as the protagonist having "parents" (plural), but otherwise no father is ever brought up.
  • Even the Girls Want Her: Due to the above-mentioned writing mishap, this occurs if you play as the female protagonist.
  • Even the Guys Want Him: Some of Arata's dialogue could be seen as him having an interest in the protagonist too, regardless of which gender they are.
  • Flat Character: To the point it's lampshaded by Nokia:
    "But the funny thing about you is you've got some pretty well-developed relationships considering how poorly developed your character is."
  • Forgotten Childhood Friend: They were friends with Arata, Nokia, Yuuko, and Yuugo during the EDEN beta test.
  • Goggles Do Something Unusual: They're the protagonist's Digivice, which are used to manage their Digimon, access EDEN, and use DigiLine. The female protagonist also uses hers as a hair tie which in turn means she can't wear them the conventional way.
  • Heroic BSoD: They hit one after they recover their memories of the EDEN beta test, as they assimilate almost completely into the recreation and the dialogue choices indicates they've snapped.
  • Heroic Mime: An odd case; their dialogue isn't written out (although their sprites and other dialogue indicate they are indeed saying something unseen to the player), but their internal dialogue is laid bare for the player to see, revealing them to be a fairly upbeat and cheerful person. The contrast is somewhat jarring in-game.
  • Magnetic Hero: Lampshaded by Nokia.
  • Missing Mom: Their mom, Yukino, is a reporter working overseas; the plan was for them to go visit her until the events of the game occurred. She keeps in touch over DigiLine throughout the game, but isn't present.
  • Ms. Fanservice: The female protagonist could be seen as this due to her Dangerously Short Skirt, Zettai Ryouiki and her rather nice figure.
  • Mythology Gag: The male default name matches how the anime leads would typically have names that started with the character "Ta", while the female's is in a more "standard" protagonist naming style.
  • Nice Guy: Generally speaking, although you're capable of making some sly remarks once in a while via the dialogue options.
  • Only Sane Man: They're a little goofy, but still easily the most normal and sane member of the main cast.
  • Out-of-Body Experience: They become a half-digital entity after being attacked by a Eater. They're still capable of manifesting in the real world, but they're separated from their real body, and express a desire to return to it.
  • The Power of Friendship: It's said that they're able to accomplish much of what they do throughout the game through their bonds with their friends and their Digimon. Ultimately, this is what allows their Digimon to gather up their data and return them to their body.
  • Purely Aesthetic Gender: The gender selection only changes their appearance and battle voice clips; other than that, it affects nothing, even scenes or dialogue choices that you'd normally expect to be made for the male protagonist.
  • She's Got Legs: The female protagonist, thanks to her Dangerously Short Skirt.
  • Silent Snarker: Although they're a sort of Heroic Mime (see above), some of their facial expressions tend to fall into this category.
  • The Snack Is More Interesting: When going out to eat, the sleuth is so absorbed in their meal they completely tune out everything around them. Nokia gets upset about this at one point.
  • Stock Superpowers: Continuing in a long standing trend of Digimon protagonists, they have explicit superpowers, mostly in terms of Super Speed. They were able to run across multiple districts of Tokyo in no time at all, and even reacted to the attacks of the Royal Knights, who are routinely depicted as being so fast, Digimon like Magna Garurumon, who is said to move faster than light itself could not keep up with them. Again, continuing in the long standing trend, these moments are almost never brought up at all, they just sort of...happen.
  • Tomboyish Ponytail: The female has a sidetail to make her "cuter" and no matter how you play her she comes across as more active and "boyish" than most of the other girls in the game barring possibly Makiko, not helped by the as mentioned issues having the male and female dialogues largely the same.
  • Zettai Ryouiki: The female protagonist is a type A.

Kyoko Kuremi

https://static.tvtropes.org/pmwiki/pub/images/digimon_cs_kyouko4.jpg
Voiced by: Maaya Sakamoto

A detective specializing in cyber crimes, possessing a philosophical streak, a detective's natural curiosity, and quite a bit of knowledgeable intuition. Upon discovering the protagonist in their half-digitized state, she recruits them as her assistant, offering to help them recover their body in exchange for them assisting her in detective jobs and an ongoing investigation into EDEN.


  • Absolute Cleavage: There's no top garment whatsoever under that jacket. (The actual 3D sprite closes it a little tighter.)
  • Affectionate Nickname: She occasionally uses "my dear Watson" for the protagonist, among other names.
  • Big Damn Heroes: Repeatedly. Most notably when she drives up and saves the player from being arrested when they materialize in the real world in their digital form. Then later when she drives straight into digital shift to help the player fight Crusadermon as Alphamon.
  • Cool Car: Perceptive players may notice that it's an Alphamon-colored Alfa Romeo Montreal.
  • Cordon Bleugh Chef: Matayoshi warns the protagonist during their first meeting to watch out for Kyoko's coffee, and he's not kidding; her "experiments" include putting in things like yogurt, sea urchin, oyster sauce, or mayonnaise. The protagonist and Arata end up hapless victims. A journal entry in Hacker's Memory reveals that her coffee making process consists of cramming ingredients like fish eyes and bean paste into a blender and then dumping the resulting goop into the coffee. It ends up as a Brick Joke, as the protagonist ultimately takes mayonnaise and coffee with them when meeting up with Kyoko in the epilogue. As it turns out, Alphamon's the one responsible for this aspect; the real Kyoko is receptive to the idea, but finds it odd.
  • Dynamic Entry: Using her Cool Car or more specifically, becoming the Cool Car to save the protagonist.
  • Leitmotif: "The Ending Has Lots of Coffee"
  • The Mind Is a Plaything of the Body: The "Kyoko" that the cast interacts with over the course of the game, despite being an empty body inhabited by a Digimon, has a personality fusion of both entities: Kyoko's intelligence, curiosity, and intuition combined with Alphamon's odd taste in coffee and "regal", slightly masculine form of speech (although Alphamon does make sure to state that this was only possible because their intentions were already similar). After Alphamon leaves and the original Kyoko's is restored to her body, she seems to have residual, unconscious memories of the experience, as she asks the protagonist if they've met before and says that she feels she's forgetting "something very important".
  • Mission Control: Her detective agency in Nakano Broadway is the home base for the protagonist's operations, and she's responsible for guiding them through detective requests and their investigative ventures.
  • Ms. Fanservice: Though only in her character design; it's never commented on or pointed out in-game, other than the generic comment every so often about her being "beautiful".
  • She's Got Legs: In case you didn't notice her artwork up there.
  • Yokai: She has an almost encyclopedic knowledge of them and Shinto folklore, and often makes comparisons of things they encounter to them.
  • You Killed My Father: Her father is believed to have been murdered in the process of investigating Kamishiro Enterprises, and Matayoshi considers it to be a huge motivation for both of them to be finishing what he started. Although Kyoko certainly has respect for her father, she never mentions it herself, probably because her priorities are more invested in the fact she's actually a Digimon who wants to save humanity and the Digital World.

Nokia Shiramine

https://static.tvtropes.org/pmwiki/pub/images/digimon_cs_nokia24.jpg
Voiced by: Megumi Han

An outspoken and positive-thinking girl whom the protagonist and Arata had met through chat and met up in EDEN, who also receives the "Digimon Capture" from an unknown source. Although initially terrified of the Digimon, she meets and bonds with Agumon and Gabumon, partnering with them in the hopes of helping them get their memories back. Eventually, after slinking away from some fights, she decides to get over her cowardice, train with Agumon and Gabumon, and form a hacker team called the "Rebels" in order to fight for Digimon well-being in EDEN.

Her partners are Agumon and Gabumon -> WarGreymon and MetalGarurumon -> Omnimon.


  • Achievements in Ignorance: Despite having almost no knowledge of hacking or of Digimon, she manages to form a hacker group of her own, evolve her partners to Mega level, and then evolve them past Mega, just through hoping something good will happen if she tries hard enough.
  • Breaking the Fourth Wall: She's fond of this, commenting on everyone's characters from time to time, although it's hard to say whether she's breaking the fourth wall or simply likes to use terms related to fiction (she at one point refers to her MP being at 0, despite no such concept existing in the game).
  • Broken Pedestal: Up until he threatened her and tried to take Agumon and Gabumon away from her, Nokia was a fangirl of Jimiken (she'll still listen to his music, but he's a target of her hatred).
  • Catchphrase: "Things will work out somehow!" She later upgrades it to "I'll make it work somehow!"
  • Clingy Jealous Girl: Is this for the protagonist as seen in the fact she gets jealous when she thinks there's another girl they're interested in, despite the fact she tries to earn every guys attention.
  • Converse with the Unconscious: The epilogue involves her, accompanied by the others, catching the comatose protagonist on what's happened since their defeat of Mother Eater, and begging for them to return.
  • Cowardly Lion: Starts off this way at the beginning of the game prior to taking a huge, huge step out of it.
  • Cuteness Proximity: After she gets a good look at Agumon and Gabumon, she is quick to think that they're cute.
  • Forgotten Childhood Friend: She was friends with the protagonist, Arata, Yuuko, and Yuugo at the time of the EDEN beta test, or at least close enough with them for Yuugo to know her personality fairly well.
  • Genki Girl: The most cheerful and outwardly excitable of the group.
  • Girlish Pigtails: She's the most Girly Girl in the game by far and they also parallel her avatar's candy-wrapper shaped head.
  • Hot-Blooded: Her impulsiveness gets her into a nasty habit of charging into events without really thinking them through.
  • Just You Me And My Guards: Attempts to pull this in the early parts of the game (with the protagonist as the guard) in order to hide the fact that she's actually terrified and incapable of doing much, until Agumon and Gabumon call her out on it.
  • Leitmotif: "PO-SI-TIVE♡pop girl"
  • The Load: Is this at first, to the point where she attempts to push any conflict onto the protagonist in the early parts of the game. She gets better.
  • Ms. Fanservice: She's quite explicitly hopeful that guys around her will be into her "sexy-cute body". Interestingly, despite the fact that her character design bares a large amount of skin, it's mostly covered up in her 3D sprites, and other characters don't comment on what they think about it.
  • The Nicknamer: To a small extent; she immediately gets clingy to Yuuko and names her "Yuukorin" ("Yuukocchi" in the Japanese version) and eventually starts calling Arata "Geeta" (geek Arata).
  • Olympus Mons: Her partner Digimon for most of the story is Omnimon, a Royal Knight and who is often depicted as one of the most powerful Digimon in the entire franchise.
  • Plucky Girl: Boy is she ever; her relentless positivity ends up being a draw factor for recruiting members into The Rebels, despite the fact that she doesn't have much hacker experience. Even during the latter half of the game, when faced with Arata succumbing to Eater and the Royal Knights looming even further, she briefly becomes a little dejected, but never fully succumbs to Heroic BSoD level.
  • Small Name, Big Ego: She's convinced she has a "sexy-cute body" and expects every male in the vicinity to be into her self-proclaimed irresistible looks. Nobody in the game ever actually disagrees, though they do show a certain degree of exasperation, and at one point someone refers to a doll that looks uncannily like her as an "ugly one done as an experiment" that isn't selling well.
  • Trademark Favorite Food: Anything having to do with eggs. When she, Arata, and the main character are sent as food critics, she always orders something with egg in it.
  • Vitriolic Best Buds: She doesn't get on particularly good terms with Arata; she considers him pretentious, while he considers her idiotic. Deep down, though, it's clear they do care for each other deeply.
  • What Measure Is a Non-Human?: After befriending Agumon and Gabumon and realizing that they're living beings rather than hacker programs, her motivation for the rest of the game becomes creating an environment where Digimon and humans can get along in peace, and hackers can stop treating their Digimon like slave programs.

Arata Sanada

https://static.tvtropes.org/pmwiki/pub/images/digimon_cs_arata21.jpg
Voiced by: Daisuke Kishio, Naomi Shindo (child)

An aloof boy who'd also met with the protagonist and Nokia in chat and received the "Digimon Capture". He has considerable skill in hacking and seems to have been part of a big-time hacker group in the past, but refuses to mention anything about it. Throughout the game, he assists the protagonist in investigating "Digital Shifts" that begin to half-digitize areas of Tokyo, expressing a particular curiosity in Eater and how to get the protagonist back to their body. Despite his cold personality, there's a much softer and compassionate side underneath...not that he'll willingly let you see that.

His partner is Keramon -> Chrysalimon -> Infermon (and predictably Diaboromon if you complete a certain sidequest near the end of the game).


  • Adorkable: Arata tries to play the role of a "cool hacker against authority", but he's actually a huge nerd and it shows through on several occasions, like when he's geeking out about manga and the player becoming a cyber sleuth. This leads to lots of teasing from Nokia and eventually Yuuko. The player can get in on it too sometimes.
  • Ambiguously Bi: As mentioned under Even the Guys Want Him Arata tries pretty hard to impress Nokia and Aiba by making himself appear more "mysterious and cool", regardless of the latter's gender. Even if both of them are girls the way it's regaining his memories of Yuugo, who is said to have been his "closest friend" when they were kids, that leads to his breakdown can come across as questionable.
  • Ax-Crazy: Shows some signs of this in Odaiba before the second Examon battle. He even has red eyes of madness!
    Arata: More, more, more... More, more, more, more and more!
  • Blatant Lies: He walked into the "ComiMani" (comic maniacs) forum purely out of interest and thought it stood for something like "Communist Manufacturing", he swears!
  • Closet Geek: Get him to talk about comics and he'll start rambling on and on about them even after you ask him to stop.
  • Dark Is Not Evil: Despite the fact that his partner's evolutionary line has generally appeared as antagonists in Digimon media, particularly in the anime, Arata himself is not a bad person in the slightest. When he goes off the deep end on his Face–Heel Turn, he doesn't even use his partner during that time, and after being brought back to normal his epiphany that he's developed into a better person is what triggers his partner's digivolution into Diaboromon - infamous for being the main antagonist in the second Digimon Adventure movie.
  • Expy: Several players draw comparisons for Arata to Sasuke Uchiha. Especially later in the game when he goes with a mysterious Mad Scientist who promises him power in order to accomplish his goals and said "power" ends up giving him a Super Powered Evilside and he ends up fighting his friends.
  • Face–Heel Turn: Briefly joins with Suedou and partially merges with Eater in the hopes of getting stronger after being reminded of his failure to save Yuugo, resulting in him going on a rampage around town and eating data. Although he doesn't completely become a heel initially as he still helps you defeat Examon, it culminates in him temporarily "eating" Gallantmon and eventually attacking you and your friends to make you "disappear". Eventually, the protagonist snaps him out of it.
  • Forgotten Childhood Friend: He was friends with the protagonist, Nokia, Yuuko, and Yuugo during the EDEN beta test. The extent of his friendship with the others isn't fully clarified, but he refers to Yuugo as his best friend.
  • The Gadfly: He enjoys being a bit of a troll to his friends, ranging from trying to scare an already clearly nervous Nokia when they first meet in person for the hell of it to giving you horrific romantic advice if you try asking him for some just to see how you'll react. Oddly enough though Nokia seems to indicate he doesn't actually do this often with his friends online as it comes up when she negatively compares him to how he handles himself as Blue Box.
  • Get a Hold of Yourself, Man!: The protagonist's response to him refusing to leave Eater is by punching him directly in the face. This causes Arata to angrily retaliate and for the two to enter a punching brawl...but his angry reaction indicates that He's Back.
  • Heroic BSoD: After his Eater form is defeated, he resigns himself to being weak and useless and unable to do anything, telling the protagonist not to save him.
  • Hidden Depths: Arata is a Sushi connoisseur, knowing several facts and even the order you're supposed to eat the different kinds in.
  • It's All My Fault: Continually a victim of this; he blames himself for not getting you out of EDEN on time to prevent you losing your body, then for failing to trigger the Tokyo blackout on time to stop the dimensional gate from opening. His repeated failure to arrive on time to save Eater victims starts to take a toll on his self-confidence as the game progresses. By the time he's reminded of the second incident described in My Greatest Failure below, he does not take it well.
  • I Work Alone: Tries to invoke this when he's about to get on the police's wanted list for causing the Tokyo blackout. Nokia calls him out for being cool, but Yuuko correctly identifies that he's trying not to get his friends in legal trouble by assuming responsibility for the crime. When the protagonist meets up with him later, he admits that being on the lam really sucks, but still tries to keep up the act anyway.
  • The Leader: Arata was the former leader of the Judes group of hackers until an attack after they raided Under Zero ended up destroying their accounts and driving some insane from fear. That being said, he gets the band back together for a last fight in Chapter 10.
  • Leitmotif: "HACKING PRIDE"
  • My Greatest Failure: Two. The first was leading Judes to Under Zero, resulting in everyone there being traumatized by the Knightmon there and the team's ultimate disbandment. The second, which gets him on a far deeper level, is hesitating to save Yuugo, his best friend, from Eater, then forgetting about the incident and Yuugo via Suedou-inflicted amnesia right after.
  • One-Winged Angel: As Eater Adam.
  • Red Right Hand: Gives himself one by assimilating an Eater. Thanks to Suedou's preparations he maintains control over it, but the resulting Horror Hunger and deadening of his empathy cement him as a villain until it's dealt with. It eventually leads to...
  • Shout-Out: He greatly resembles the protagonist of Devil Survivor 2 in terms of apperance.
  • Tsundere: In spades. He has a tendency to react with embarrassment and denial anytime you uncover a softer side of his personality, which only spirals it down further.
  • Vitriolic Best Buds: Nokia isn't fond of his cold attitude of "trying to act cool" and Arata isn't fond of her Hot-Blooded impulsiveness and occasional stupidity, so they tend to butt heads a lot, but ultimately they are friends and Arata seems to get legitimate fun out of teasing her.
  • Would Hit a Girl: The scene in which he punches the protagonist in the face takes place regardless of selected gender. To be fair to him, she did punch him first.

Yuuko Kamishiro

https://static.tvtropes.org/pmwiki/pub/images/digimon_cs_yuuko21.jpg
Voiced by: Kanae Ito

The polite and reserved daughter of Satoru Kamishiro, who had been president of EDEN's parent company Kamishiro Enterprises until his sudden and mysterious suicide. Believing that there's no way her father could have committed suicide, she enlists the help of you and Kyoko to help investigate. She also takes a personal interest in EDEN Syndrome, as someone close to her seems to be a victim of it. Her Digimon partner is a Gaiomon.


  • A Darker Me: After learning that Crusadermon killed her father, she noticeably takes on a few more cold and biting/sarcastic traits at certain moments, which the others jokingly refer to as "Yuuko the Blackhearted". Kyoko notes that she's been putting on so many different kinds of "masks" (the president's daughter, the leader of a team of hackers, a shy and lonely girl) that she's starting to display other unprecedented sides to her personality.
  • Ambiguously Bi: In her introduction, Rie wonders aloud whether or not Yuuko might be hiding someone in the hospital ward, perhaps a boyfriend or even a girlfriend. Whether this is Rie's legitimate insight into Yuuko's preference or just Rie being Rie is unclear.
    • She does end up acting fairly Tsundere towards both the male and female protagonist, although that may have to do with certain writing-related mishaps (see Purely Aesthetic Gender above).
  • Berserk Button: Anything relevant to her father's death - her reaction to Kyoko mentioning his suicide is yelling firmly that her father would not commit suicide, and after Crusadermon is revealed as his murderer, the mere subject sends her into Tranquil Fury.
  • Big Eater: She's often caught hanging around restaurants checking out some large food deal, and a sidequest reveals she can eat portions for multiple people and still be hungry. She also happens to be an online hobby food reviewer in her free time. Also, when asked about what her ideal romantic gift would be: it's "a huge onigiri filled with love".
  • Cute and Psycho: After apologizing for saying cruel things to the protagonist when out for revenge on Crusadermon, she puts on this demeanor when insisting that they forget about it, leading to them labeling her "Yuuko the Blackhearted".
  • Expy: Visually, she resembles Yuuya, having similar fashion sense and also being the child of a major corporation's leader. That's where the similarities stop, though.
  • False Flag Operation: Uses the detective agency as a patsy and a fake name so she can investigate the account raiders attacking EDEN without being identified by her ties to the Kamishiro Corporation or her secret identity as the head of Zaxon.
  • Forgotten Childhood Friend: She and her brother were friends with the protagonist, Nokia, and Arata during the EDEN beta test.
  • Friendless Background: She has poor social skills and little experience in having friends, as when told to act like the protagonist is her school friend she believes that this means she has to act like a Tsundere towards you. She also has a poor grasp on what it means to be a friend, and it takes a while before she acknowledges you as one. It seems that she'd been friends with the protagonist, Nokia, and Arata as kids, although to what extent is unknown, and her memories of them were wiped after the EDEN beta test incident.
  • Heroic BSoD: After discovering that Rie had been manipulating her actions every time she'd been acting as "Yuugo", she falls into despair and tells the protagonist to give up on rescuing her because everything she'd done had been for nothing. The protagonist and Fei's TigerVespamon have to remind her that she's not alone in order for her to recover from it.
  • Leitmotif: "MESSAGE", which notably isn't named after her but the significant yet unrelated event it's used in (Nokia's message to the comatose protagonist in the epilogue).
  • Not So Stoic: At any mention of her father's death if it's anything related to suicide.
  • Ojou: Played with; although she's the daughter of the former Kamishiro Enterprises president and is able to use her connections to get the protagonist and Kyoko in when they need to do investigations, she's not of age and is thus given few access privileges while Rie is the company head. She does take control of leading the company when Rie's disappearance causes it to go into disarray, though it's not said whether this is an official position. It's also implied she has quite a bit of money; when she submits a request as "Yuugo", Kyoko mentions that "he" paid it off right away and comments that "he" must be of good upbringing, and later when Nokia runs out of money to help supply Agumon and Gabumon's massive appetites, she foots the entire bill for everyone present and takes them all out for dessert.
  • Parental Abandonment: What happened to her mother is never mentioned or explained, but her father's death and her brother falling into EDEN Syndrome is said to have left her with no family. Although Satoru is restored to life after the Cosmic Retcon, the epilogue also has Nokia comment that with Rie making moves on Yuuko's father, she may very well end up becoming Yuuko's new mother, meaning that Satoru indeed does not have a currently living wife.
  • Revenge: Alphamon's original plan is just to finish dealing with Crusadermon for the time being and leave, but Yuuko wants revenge for her father's death. She gets it.
  • Shrinking Violet: She's aloof and fairly shy. It's for this reason that the "Yuugo" avatar comes with an artificial personality, as she wouldn't have been able to lead Zaxon with her own demure disposition. She does, however, have the capacity for some well-timed cold remarks, which the protagonist and Nokia jokingly refer to as "Yuuko the Blackhearted".
  • Take a Third Option: Upon visiting Fei and Keisuke at the Central Hospital, her and Fei's relationship is called into question by Keisuke. When asked by the two to clarify what she views the relationship as, she opts to neither confirm it as platonic or romantic, instead simply saying how Fei is "precious" to her and that their relationship is something that cannot be put into words.
  • Tranquil Fury: She becomes very cold and passive-aggressive to you as you accompany her after discovering that Crusadermon was responsible for her father's death; although she never gets to the point of violent anger, she gets extremely frustrated with you for supposedly taking the situation too lightly and even denies that you're her friend. She apologizes for it later.
  • Tsundere: After you save her from Eater, Nokia comments that she was very worried about you during your absence...to which she stammers and protests that it's not like that and she just wanted to thank you.

Voiced by: Miyuki Sawashiro

A character originally hailing from Digimon World Re:Digitize who's friends with Kyoko, manages the DigiLab where the protagonist can manage their Digimon, and occasionally provides assistance in their hacking endeavors. She carries a mysterious demeanor and is a firm believer in "fate", describing her own presence as being a product of that.

Her partners are Angewomon and LadyDevimon -> Mastemon.


  • All There in the Manual: A game-shaped manual in this case; her general nature is left unexplained in this game, and understanding it fully requires playing Digimon World Re:Digitize Decode (a game that, despite being in the same franchise, is technically part of a separate series) to the end. The website for this game gives a few details at the cost of spoiling the other.
  • Bonus Boss: Both as one of the enemies in the Offline Colosseum and the final challenge in the Demon Lords DLC as she goes off the wall attempting to make the "ultimate Digimon" from the Seven Sins pieces.
  • Cordon Bleugh Chef: She's responsible for suggesting strange coffee recipes to Kyoko, although knowing her personality she could easily just be taking amusement from the results.
  • Dimensional Traveler: She's not from this world and has connections to multiple others. Mastemon also has the ability to create dimensional portals, although since creating her requires items that she doesn't have at the start of the game, how much access she has to this ability is unknown.
  • Expy: She's a mysterious and elusive manager of a hidden, extradimensional monster management room, much like Elizabeth; she even has the same voice actress.
  • Fusion Dance: The scene in which Angewomon and LadyDevimon DNA Digivolve into Mastemon is...quite something.
  • Late-Arrival Spoiler: Her official profile on the game's Japanese website spoils the final plot twist in Digimon World Re:Digitize Decode, in that she lost her physical body in an accident.
  • Older Than They Look: Her chest might give it away, but according to her game of origin, she's actually an adult woman.
  • The Tease: She comes off as this, partially due to her voice actress playing up this aspect of her in her performance, partially due to her tendency to use language like "fate drew me to you". (She likes using this language on other people as well, as she refers to the protagonist similarly as Sayo's "fated person" in reference to them being the one to save her Dianamon.)

Rina Shinomiya

https://static.tvtropes.org/pmwiki/pub/images/digimon_cs_rina10.jpg
Voiced by: Haruka Tomatsu

A girl who hails from Digimon World Re:Digitize Decode and its corresponding Alternate Universe. Mirei sends the protagonist to meet her in order to recruit her Veevee as the Royal Knight UlforceVeedramon. An incredibly aggressive and tomboyish girl, she's described as annoying, oh so very annoying...and cute.

Her partner is Veevee, a Veemon -> UlforceVeedramon.


  • Big Eater: She considers food to be one of the most important things in the world, and her introduction of the human world to Kentaurosmon ends up being endlessly dragging him to restaurants.
  • Boisterous Bruiser: She's incredibly fun-loving and her first reaction upon entering the protagonist's world is deciding that she wants to tour around the town. Her free-spirited nature is eventually what convinces Kentaurosmon to back down and give humanity a chance.
  • Bonus Boss: Near the end of the game, she and Veevee are the first bosses in a series of quests that unlock the ability for you to make your own versions of UlforceVeedramon and the other Royal Knights.
  • Calling Your Attacks: She and Veevee like to call his finisher together...except she keeps getting it wrong, like saying "Spray of History" for "Ray of Victory"note .
  • Cloudcuckoolander: Pretty much the basis of her entire character in-game, to the point where absolutely no one can keep up with her randomness. Not even a Royal Knight.
  • Combat Pragmatist: She waits for an evil lord digimon to start his villainous gloating before drop kicking him in the face.
  • Did You Just Punch Out Cthulhu?: In an action that would make Masaru Daimon proud, she kicks the Demon Lord Barbamon in the face.
  • Dumb Muscle: She's incredibly physical and impulsive but also incredibly absent-minded, charging into situations regardless of consequence and shrugging off half the things she's told because she doesn't understand enough to care.
  • Genki Girl: So much that her "idle" animation isn't idle as much as her jumping around ready to start a physical brawl.
  • Goggles Do Nothing: Nothing that we see, but in series it's a good and reliable visual shorthand for "Digimon protagonist".
  • Large Ham: Likes to overdramaticize everything she talks about (mostly to Veevee's exasperation). Culminates in her and Veevee giving each other a dramatic, tearful farewell as they promise to meet again (despite the fact that they're only going to be temporarily separated)...only for her to follow you through the gate anyway.
  • Like Brother and Sister: She and Veevee have this kind of relationship, with a hint of Foolish Sibling, Responsible Sibling, with Rina as foolish one and Veevee as the responsible one.
  • Motor Mouth: Rina's boundless energy means she can talk a mile a minute and does so most of the time.
  • Out-of-Body Experience: Apparently being outside her own world leaves your physical body in your world of origin and makes you into a digital entity. Rina takes an alarmingly low amount of concern about this and in fact finds it cool to be "like a Digimon".
  • Vague Age: In her game of origin, she was depicted as what would be the age of a middle school student at the oldest, but in this game she's depicted to be around the same age as the mid-to-late teenager cast. This could also be a stylistic difference; despite the fact both games were by the same artist, Mirei, who shouldn't look older because she has no physical body, also goes through the same treatment.
  • Whatever Happened to the Mouse?: After her side quest towards the end of the game we never see her again. She doesn't join you for the final battle and she isn't mentioned in the epilogue.

Pete

A Wanyamon discovered within Nakano Broadway in an early sidequest, who seems to be the manifestation of a "time capsule" left in an old vacuum tube computer in Nakano Broadway. Or, at least, it's only Kyoko's theory; he's actually the cat of a man named Yoshito Mizushima who used to work in the computer room, and was trapped there when the room was sealed off; the power of the Digital Wave within it caused him to merge with the computer and become a Digimon. He becomes a helpful assistant in a few sidequests.


  • Amnesiac Dissonance: Although there's no moral alignment associated with it, the trauma and confusion of his conflicting identities of "Pete", named and given an identity by Kyoko, and "Miko", named and given an identity by a man named Yoshito Mizushima, is enough to almost give him a mental breakdown.
  • Dead All Along: Possibly implied; Kyoko notes a number of strange things that don't line up with logic when he and Yoshito reunite...but ultimately the protagonist chooses not to pursue it at Pete's request.
  • Fish out of Temporal Water: Because he's a time capsule (or, actually, because Yoshito told him), he's aware of and talks about quite a few (in-universe) pop culture references that nobody around him recognizes.
  • Identity Amnesia: He doesn't remember anything about himself or who he is, and he assists Kyoko because she takes an interest in discovering it.
  • I Just Want to Be Normal: Once he remembers who he is, his final request to the player is to leave him and Yoshito alone- he does not wish to be found and would rather spend his remaining days with Yoshito as a normal cat: Miko. Thus, they are never again seen nor mentioned in the game.
    Pete: Please, leave us be... Don't go looking for us.
  • Mission Control: Takes this role during Kyoko's absence in chapters 12-15.
  • Peaceful in Death: Heavily implied at the end of "Ghost Cat Building": the final cutscene is of Yoshito and Miko leaving together. But what makes the implication stronger is that, rather than walking on the building, they seem to be walking on the screen instead- giving the illusion that either Yoshito or Miko, or perhaps both, will die soon- and happily together. Kyoko's monologue at the end of this quest can be taken as a kind of eulogy.
    Kyoko: Not all mysteries in this world need to be solved.
  • Time Capsule: He's the personification of a time capsule filled with data from a few decades past, stored in an unused computer system within Nakano Broadway. Or at least, that's what Kyoko initially believes.
  • Uplifted Animal: It's theorized that Pete/Miko was a cat that was caught in the wall with the vacuum tube computer that was affected by Digital Waves and became a Digimon.

Goro Matayoshi

https://static.tvtropes.org/pmwiki/pub/images/digimon_cs_matayoshi9.jpg
Voiced by: Masaru Ikeda

A senior detective known in his department for being a bit of a Determinator with an obsession around discovering the truth, and a friend of Kyoko's late father who's known Kyoko since her childhood. He's rather inexperienced with modern technology, so he often drops by the detective agency for advice and considers it his "secret weapon". Due to his past experience with it, he provides valuable information in the Kamishiro Enterprises investigation.


  • Affectionate Nickname: He calls Kyoko "Kyo-chan" despite her being a grown woman, saying that because he's known her for so long, Kyo-chan will always be Kyo-chan to him.
  • Cool Old Guy: Though stern, he gets along well with much of the cast. He's particularly interested in the protagonist and watching their development as an Amateur Sleuth, since they're Kyoko's protegé.
  • Locked Out of the Loop: Although he's aware of the fact the protagonist and their friends are trying to stop an oncoming world destruction plot, since he doesn't have a full grasp on the situation, he ends up having to leave it to them while he tries to explain their actions to the higher-ups.
  • Reasonable Authority Figure: Although "reasonable" might be a little stretched since he technically assists the main cast in their questionably legal hacking actions. He does, however, try his best to protect Arata when the police department attempts to scapegoat Arata and the other hackers for the incidents around Tokyo.

Makiko Date

https://static.tvtropes.org/pmwiki/pub/images/hackersmemoryjp20th_4artbook_157hackersmemory.jpg
Voiced by: Masumi Asano

A detective who works under Matayoshi, who seems to know a thing or two about Arata's past as a hacker. Although her aggressive and abrasive attitude causes her to initially have a bad opinion of the protagonist and the detective agency, she eventually forms a good relationship with them.


  • Cuteness Proximity: Towards a lost Lopmon looking for their friend Tokomon she comes across and brings to the protagonist as a client.
    • Hacker's Memory has her at one point subjecting Keisuke, who was at the time disguised as a Poyomon, to a Marshmallow Hell until she's reminded that she should be working and give Yu back his "Digimon".
  • Defrosting the Ice Queen: She starts off considering Kyoko's agency - and the protagonist by extension - suspicious, and even until late in the game has a habit of threatening to arrest them, but builds a far better relationship with them afterwards (while still threatening to arrest them).
  • Disproportionate Retribution: Played for laughs. Every time you meet her she'll threaten to arrest you for some reason or other, like being depressed when Kyoko goes missing later in the game.
  • Establishing Character Moment: Threatening to arrest people for making a scene around the player character after having his damaged digital avatar shunted into the real world by an Eater, then threatening to arrest someone for calling her an "officer" when she's actually a detective, Then threatening to arrest the player character for "being gross".
  • Foil: To Kyoko. Though they share a vocation, the two female detectives couldn't be any more different from their appearances to their general attitudes.
  • Hair-Raising Hare: A Lopmon that she ends up assisting eventually becomes an Antylamon that serves as her partner in Hacker's Memory.
  • Has a Type: When taken along on cases in Hacker's Memory this topic may come up, and as it turns out it's "strong, dependable, and always remembers what others have done for them" or, as others occasionally point out, Ryuji.
  • Japanese Delinquents: She talks like one, despite being a law-enforcing detective.
  • Jerk with a Heart of Gold: She's aggressive and quick to say rude things, but she does have everyone's best interests at heart, and particularly idolizes Matayoshi. She also at one point grudgingly admits that a Lopmon is "cute". She's also capable of holding quite civil and occasionally even cheerful conversation with the protagonist over DigiLine (although most of them happen to involve Matayoshi, who's her effective soft spot).
  • Tsundere
  • Undying Loyalty: To Matayoshi; she's constantly concerned about his welfare, and at one point she suggests she'll have to be the one to take care of him if he quits the police force.
  • Wacky Marriage Proposal: Toward the end of Hacker's Memory she demands that Ryuji return safely so she can arrest him for life. Chitose is quick to point out that that sounded like the weirdest proposal ever.
  • You Remind Me of X: Matayoshi is particularly fond of her as his junior, since she reminds him of himself when he was a younger detective and believes she'll grow into a great one.

Ryouta Takei and Sakura Fujisaki

Voiced by: Hiroshi Okamoto (Ryota) and Umeka Shouji (Sakura)

Two of the protagonist's classmates. Ryota has a less-than-subtle crush on Sakura, whose love for the singer Jimmy KEN's music has lately caused her to become worringly absent-minded.


  • Cloudcuckoolander: Sakura comes off this way, although Ryouta notes that she's been like this ever since she became obsessed with Jimmy KEN, and indeed her DigiLine messages are far more coherent than her speech.
  • Declaration of Protection: Kyoko forces one from Ryouta when questioning him how he likes Sakura in what way.
  • Match Maker Quest: After Sakura is saved from the Jimiken hypnosis incident and lands in the hospital, the protagonist ends up helping Ryota pick out a present for Sakura that, with progressively decreasing levels of subtlety, is eventually revealed to be something he hopes to ask her out with. In addition, you can try egging on their relationship through DigiLine responses. A late-game DigiLine message reveals that they've started dating, although it's not mentioned whether this applies after the ending's Cosmic Retcon.
  • Those Two Guys: They ultimately are for comedic and light-hearted value; the most they factor into the plot is Sakura becoming one of the Jimiken hypnosis victims, and afterwards their tale is told only in a sidequest.

The Inoden Occult Research Club

A high school occult club that requests Kyoko's help in investigating an urban legend, and occasionally factors into a few sidequests. They're led by Mei, who has a boundless sense of enthusiasm for the occult. Four members (Mei, Kenji, Manaka, and Lily) are seen throughout the course of the story.


  • Beneath the Mask: One case with Manaka involves her DigiLine account being hacked and sending messages that she didn't write. What's unusual about it is that the messages do, in fact, reflect her actual feelings - her true feelings, as in the kind that wouldn't be socially acceptable to let public.
  • Maid Cafe: Lily runs a part-time job in one, and thus is always seen in a maid outfit.
  • Maybe Magic, Maybe Mundane: Although the other cases turn out to have mundane (or at least mundane by in-universe logic) explanations, the case of Shibuya Hirasaka most notably does not, and it's left ambiguous whether the girl involved is an actual dead, vengeful spirit. Kyoko drops it under the justification that her jurisdiction lies in cyber crimes, and not in the occult.
    • The Shibuya Hirasaka case is expanded on in Hacker's Memory, as well as the group as a whole. Lily is in fact an exorcist, and whenever she's trying to derail the group's investigations it's because they're legitimately dangerous. The Shibuya Hirasaka case ended with the group accidentally linking the worlds of the living and the dead, and after the brief connection to the Digital World the girl's vengeful spirit fused with a Dragomon, not entirely unlike the cat that became Pete, and sought to use its power to take advantage of the linked worlds to flood Shibuya with undead. After stopping this and exorcising the spirit, the group pushes Lily into training them all to be exorcists in order to help lighten her work load, and to be able to defend themselves if their meddling ever steps into the legitimately supernatural once more.
  • Shipper on Deck: Lily, for Manaka and Kenji.

Reiko Tawa

https://static.tvtropes.org/pmwiki/pub/images/digimon_cs_reiko1.jpg
Voiced by: Ayana Taketatsu

A worker at the Shibuya Records store, who sends the protagonist a request to deal with a mysterious CD appearing around the store. She eventually bonds with the culprit, an Etemon whom she happens to like the eccentric music of.


  • Crossover: On a meta-level, she's the Tower Records Japan mascot in real life.
  • Dreadful Musician: Her singing is enough to make everyone in the area cringe.
  • Meaningful Name: "Tawa Reiko" = "Tower Records".
  • Product Placement: She's basically a walking advertisement for Tower Records in the game; she even promotes it in her lines. The localization ends up turning it into a Lawyer-Friendly Cameo by making it "Shibuya Records". (The only other reason she's in the game is a reference to the fact she's designed by Suzuhito Yasuda, the character designer for this game.)

Sayo

https://static.tvtropes.org/pmwiki/pub/images/digimon_cs_sayo7.jpg
Voiced by: Ai Maeda

A girl who appears only in the Demon Lords DLC and originates from the Digimon World Dawn/Dusk pair of games; she identifies herself as a "Tamer" from Darkmoon City, in an Alternate Universe. Mirei introduces the protagonist to her in order to help her recover her partner Dianamon, which can only be done through the defeat of the Seven Great Demon Lords.


  • But Now I Must Go: She returns to her own world after the protagonist rescues her Dianamon, though she promises that they'll meet again.
  • Cutting Off the Branches: She's referred to officially as the protagonist of Digimon World Dusk, meaning that its selectable male player character is non-canon.
  • Downloadable Content: Her missions. She serves no purpose to the main story and after she appears she will stay in the Digi Lab until you complete all of her cases. None of the other main characters except Mirei and the player interact with her in any other way.
  • Gameplay and Story Segregation: The game states that Sayo defeated all Seven Great Demon Lords previously with her Dianamon, prompting the events of her quest. Dianamon, however, is a Data type Digimon with low defenses. In standard play, if it were to go up against any of the 7, it would most likely lose if not struggle greatly due to the disadvantage. Additionally, none of Sayo's other Digimon that she regularly used alongside Dianamon in Digimon World Dawn are mentioned or present.
  • Goggles Do Nothing: Other than signify, like most other Digimon media, that she is/was a protagonist in some way or form. In this case the protagonist of "Digimon World Dawn/Dusk".
  • Guest-Star Party Member: After you help her get Dianamon back, she assists you in fighting Mirei,
  • I Work Alone: She initially refuses the protagonist's help on account of her "pride as a Tamer", but Mirei reminds her that there's literally nothing she can do; she can't fight the Demon Lords without Dianamon, but she can't get Dianamon back without fighting the Demon Lords. After grudgingly accepting help, she eventually warms up to the protagonist as they display their strength.
  • Nice Job Breaking It, Hero!: Her defeat of the Seven Great Demon Lords caused their power to disperse to other Alternate Universes, and the resulting "sin" caused her Dianamon to disappear. Thus, the only way to get Dianamon back is for the protagonist to defeat the Demon Lords in their own world. Of course, this leads right to the protagonist committing the same "sin", but thanks to Mirei's meddling, they end up not having to lose their own partners.
  • Tsundere: Although her initial reaction to the protagonist is legitimate disapproval of them having to rescue her, before she warms up to them completely her reactions to them taking out Demon Lords one by one are all along the lines of "...not bad".

    Hackers and Enemies 

Eater

https://static.tvtropes.org/pmwiki/pub/images/digimon_cs_eater1.jpg
Eater (Pure Breed form)
Click here  to see the Humanoid form
Click here  to see Eater Eve
Click here  to see Eater Adam

The main antagonist of the game, Eater is less of an "antagonist" and more of a malevolent entity that has no real will and corrodes all data it touches. Its physical contact with the protagonist causes them to become a half-digitized entity, it mutates real-world areas into "Digital Shifts", and eats the "mental data" of any human it comes into contact with, throwing them into EDEN Syndrome. It also has the ability to use the data it "eats" to "evolve", taking on new forms accordingly.


  • The Assimilator: It doesn't directly copy the abilities or attacks of what it absorbs, but it takes on forms similar to it and becomes more powerful.
  • Baleful Polymorph: their real (and presumably far more harmless) form is a glowing ball of light. It seems that contact with the human world is what twisted them so much.
  • Big Bad: Partially so; because it has no intelligent will, most of its actions are chaotic/random or being controlled by someone else, but it's the effective cause of everything that happens in the game.
  • Eldritch Abomination: Its Pure Breed form resembles some kind of otherworldly squid, and its other forms are rife with moving parts that shouldn't be moving in that way.
  • Expy: Of the D-Reaper from Digimon Tamers, as it's a non-human, non-Digimon Eldritch Abomination that has a corrosive nature that is eventually defeated by reverting it to a more harmless form. Unlike the D-Reaper, however, it has no real will.
  • Hive Mind: All the Eaters are connected via one network tied to the core, which Yuugo exploits to communicate and is ultimately using to keep it from rampaging even further.
  • Horror Hunger: All they want to do is consume, preferably humans.
  • Load-Bearing Boss: If an Eater is causing a Digital Shift, defeating it causes the area to go back to normal. It also works temporally; if you completely destroy Eater via its core, it will become as if Eater never existed.
  • More than Three Dimensions: Suedou and Alphamon eventually speculate that it may have come from a "higher dimension", although its true nature remains unknown.
  • Powered by a Forsaken Child: Both "powered" and "limited"; Yuugo Kamishiro is its current active core; his presence is inducing it to eat humans, and it's implied that his negative feelings of isolation and abandonment are contributing to Eater's rampage. At the same time, he's also acting as a limiter on it through its Hive Mind. Without his presence as a "conscience", it would be liable to eating everything without restraint.
    • Hacker's Memory shows what would happen without Yuugo acting as a limiter. Erika ends up creating her own Eater Bits to serve her, but once her illness incapacitates her they immediately turn on her, use her connection to EDEN, and within hours EDEN is replaced entirely by "Eater EDEN".
  • Unmoving Plaid: Each form past the initial squidlike one has parts that are textured this way, to emphasize how otherworldly and wrong they look.

Rie Kishibe

https://static.tvtropes.org/pmwiki/pub/images/digimon_cs_rie14.jpg
Voiced by: Aya Hisakawa

A high-ranking member (and later CEO) of Kamishiro Enterprises, a flirtatious and unsettling woman whose motives are impossible to decipher. Yuuko knows her well, but is wary of her, and she stands as an obstacle to the protagonist and Kyoko's attempts to investigate her company.


  • Ambition Is Evil: She's described as having quite a bit of greed and ambition prior to her ascendancy to the position of president, to the point of having plotted to ruin Satoru Kamishiro's name and take his position.
  • Bitch in Sheep's Clothing: Plays herself up as being like a caring foster older sister to Yuuko (who isn't buying it, especially after she threatens to "accidentally" do something to her comatose brother). Even with Crusadermon's presence this is indicated to be her actual personality to some extent, given how despite their open hatred of humanity Crusadermon still says Kamishiro's murder was more Rie's will than their own.
  • Crapsaccharine World: The secret room made in her image is filled with overly saccharine decor not quite unlike that of Dolores Umbridge.
  • Evil Counterpart: To Kyoko Kuremi, both being Royal Knights in human hosts and she is what Kyoko Kuremi could have become if she takes the extreme path like her.
  • The Fake Cutie: She has very cutesy and saccharine mannerisms, but no one is really fooled by it.
  • Femme Fatale: She's incredibly seductive to the men she meets, though the "childlike" nature she takes with it gives it a definitively creepy edge. Especially since it's revealed that, as Crusadermon, she actually detests all of humanity.
  • He Who Fights Monsters: Crusadermon isn't very happy with becoming an accursed human as part of the plan to Kill All Humans.
  • Karma Houdini: This doesn't apply to Crusadermon, but the original version of her is still described as having attempted to hijack Satoru Kamishiro's position as president and harboring murderous intent towards him, yet in the "new Tokyo" provided by the Cosmic Retcon she retains her high-ranking position and seems to be seducing the president, to the point where she might end up becoming Yuuko's stepmother!
  • Meaningful Name: "Kishi" means "knight", and of course, her true identity is...
  • The Mind Is a Plaything of the Body: Rie's "ambition" was apparently what influenced Crusadermon to murder Satoru Kamishiro, despite the fact that her mind was not currently in her body. Her other negative and abhorrent emotions didn't give Crusadermon a much better opinion of humanity, either.
  • Obviously Evil: Her unsettling disposition makes it very clear from the moment she appears that she's not going to be on the side of the good guys.
  • Psychopathic Manchild: Part of the reason her demeanor is so unsettling is that she's channeling a ton of childlike Moe tropes despite being a grown woman.
  • Really Gets Around: She claims that she had dozens of boyfriends at Yuuko's age and suggests she do the same.
  • Say It with Hearts: Used for intentionally nauseating effect in the Japanese version.

Akemi Suedou

https://static.tvtropes.org/pmwiki/pub/images/digimon_cs_suedou1.jpg
Voiced by: Hiroshi Yanaka

A mysterious scientist who works for Kamishiro Enterprises and happens to be investigating the Eaters, providing useful information about his findings to the protagonists. His real motives are vague, however, and seem to extend beyond simple interest.


  • A God Am I: His final plan is to hijack Mother Eater and use its power to remake the world. Interestingly, he doesn't want power for the sake of it - he just wants to be the one to do it in accordance with his own vision.
  • Assimilation Plot: His wish is to make the real and digital worlds "perfect", and ends up aiding a plan to rip a dimensional portal open and start mingling them. His ultimate goal is to make the world "evolve" through Mother Eater's power, creating a world where "no one will feel sadness anymore".
  • Big Bad: The form Mother Eater takes when he hijacks it is the final boss for the game.
  • Gender-Blender Name: Akemi is generally a female name in Japan.
  • Heel–Face Revolving Door: It's hard to say exactly what side he's on; he offers his assistance to the protagonists on multiple occasions, providing them necessary information they need and even bailing them out once or twice, but also happens to be assisting Crusadermon's plan to wreak dimensional havoc. The protagonists are aware that he's working for his own ends, and regard him with a shade of distrust even when he's helping them out. Ultimately, he ends up on the heel end as his motives become too selfish for the others to allow.
  • Heroic Sacrifice: His reinitialization of King Drasil erases his existence in the "new Tokyo" so that he was never born.
  • Mad Scientist: He gives off this vibe from his very first appearance, looking quite visually unhinged.
  • One-Winged Angel: Merges with the Mother Eater and King Drasil/Yggdrasil so he can remake the world as he sees fit, becoming the Final Boss.
  • Opportunistic Bastard: He's not on the good guys' or bad guys' side; he'll help whatever side is convenient for him at the moment.
  • Noble Demon: His plan to save Satoru Kamishiro, whom he apparently respected deeply, involved using an Eater to absorb the mental data of the potential perpetrator and an innocent bystander. It didn't even pan out anyway because it led to Crusadermon possessing Rie's body and murdering him anyway - but he didn't seem to mind that as long as Crusadermon's plan was beneficial to his own ends.
  • Pet the Dog: He wiped the memories of the survivors of the EDEN beta in order to spare their sanity of seeing an Eater attack.
  • Ret Gone: Reinitializes King Drasil from within Eater, causing everything to converge and making it so that he was never even born in the universe of the Cosmic Retcon.
  • Screw Destiny: The protagonist's actions convince him not to resign himself to the world being fated to end in sadness and accept the infinite possibilities in the world, leading to his Heroic Sacrifice.
  • Well-Intentioned Extremist: Even though he acts as the Big Bad of the game, the worst thing he tries to do is evolve the human race to the point where there's no sadness, and he's genuinely baffled that the heroes would prefer the current, flawed world to the one he's proposing.
  • Wild Card: One second he'll be helping you, the next, he's helping your enemies. Really he'll do whatever he finds of value regardless of what others may think or what may be considered ethical.

Yuugo

https://static.tvtropes.org/pmwiki/pub/images/digimon_cs_yuugo24.jpg
Voiced by: Ayumu Murase

The leader of the hacker team Zaxon, and the first person the protagonist meets in EDEN. Despite leading a group of malicious hackers, he himself is cordial, teaching the protagonist how to use their Digimon Capture and occasionally restraining the hackers from becoming too much of a nuisance. However, he has his own personal goals and refuses to let anyone get in his way. For some reason, he bears an uncanny resemblance to the "white boy ghost" making appearances around EDEN, but he himself claims to merely be an elusive human.

His partner is Machinedramon.


  • Angst: After hearing about his actions in regards to Nokia and the Rebels, Kyoko concludes that despite his good intentions, he's really just going through a ton of teenage angst.
  • Anti-Villain: Despite the fact he's the leader of one of the most prominent hacker groups in EDEN, the members of which wreak havoc on its users, he himself doesn't take part in that kind of activity, assists and saves the protagonists at multiple points in the narrative, and even professes disappointment at the current state of EDEN. His stated goal is to unite the hackers and protect EDEN out of love for it; it's just that he doesn't treat anyone who gets in his way kindly. He's also out to investigate Rie and Kamishiro Enterprises, and wants to mobilize the hackers of Under Zero to break in so he can find the truth.
  • Everyone Has Standards: Despite how openly he makes membership to Zaxon available he still felt the need to personally throw Jimiken out of the group for single-handedly breeding a large criminal subculture in the group.
  • Leitmotif: "We Bring Glory to ZAXON"
  • Rebel Leader: He claims to work for the "freedom" of hackers in EDEN so that they can do what they please, and eventually mobilizes them to assist him in a large-scale attack on Under Zero.

Fei Wong Tomoe Ignacio

https://static.tvtropes.org/pmwiki/pub/images/digimon_cs_fei13.jpg
Voiced by: Seira Liu

Yuugo's right-hand woman, of half-Japanese, quarter-Chinese, and quarter-Brazilian lineage with a Kyoto dialect. She has a calm but sadistic edge to her, a particularly hostile relationship with Nokia, and a very devoted sense of loyalty to Yuugo.

Her partner is TigerVespamon.


  • Accent Adaptation: She appears to have been given a kind of Southern Accent in the English version of the game.
  • Ambiguously Gay: Throughout the game she's presented as extremely devoted to Yuugo/Yuuko, to the point where she's shedding tears of joy after she's saved from Eater Eve. Nokia lampshades this, teasing Fei about whether or not she wants more than just friendship. A journal entry in Hacker's Memory is summarized as her attempts to impress a lover (implied to be Yuuko), with said lover's pronouns being female, which seems to confirm that she's attracted to girls.
    • Ambiguously Bi: Or possibly better described as Single-Target Sexuality, considering that she has no mental issue whatsoever swapping between referring to Yuuko in her "Yuugo" and normal female personas, and uses the same loving words for both.
  • Because You Were Nice to Me: Yuuko/"Yuugo" was the one who gave her TigerVespamon, giving both of them a "place to be" (with each other).
  • Break the Haughty: Getting Curbstomped by Nokia and Omnimon then having Yuuko kidnapped breaks her ego and causes her to become more genuinely helpful.
  • But Not Too Foreign: Her parents were apparently Japanese and Chinese-Brazilian, according to her official profile (it's never brought up in the game beyond her name). Her name is accordingly a mix: Fei Wong (Chinese) Tomoe (Japanese) Ignacio (Brazilian).
  • Color Motif: She is associated with the color yellow. Not only does she sport it on her outfit, but all three of her party Digimon (including her signature) are primarily yellow in color.
  • Easily Forgiven: Averted. While Keisuke, Chitose, Wormmon, Makiko & Matayoshi ultimately give Ryuji a pass for his actions, Fei remains unconvinced and explicitly states that she won't forgive him. Justified in that he did attempt to kill her and the woman she loves. She only puts aside her wrath due to Yuuko's insistence and the more pressing issue of the Eaters at hand.
  • Not So Different: She notes that she and Nokia are quite similar in certain ways...before declaring that she hates her own kind and attacking her anyway.
  • Secret Keeper: She was aware of "Yuugo"'s true identity as Yuuko, and the fact that the avatar was based after the real Yuugo Kamishiro.
  • Undying Loyalty: To Yuugo, to almost obsessive levels; Nokia assumes that she must be in love with him.
  • What Happened to the Mouse?: We never find out what happened to her relationship with Yuuko after the Cosmic Retcon, and if it's been affected in any way.
  • What Measure Is a Non-Human?: She considers her Digimon to be programs and is alarmed when they begin "acting against orders". However, she does seem to find value in being with TigerVespamon even when seeing her only as a program.

Jimiken (Jimmy KEN)

https://static.tvtropes.org/pmwiki/pub/images/digimon_cs_jimmy4.jpg
Voiced by: Cota Nemoto

A famous rock star in the real world who also happens to be a particularly arrogant and malicious hacker. Although he starts off a member of Zaxon, he forms his own group called Demons after being kicked out by Yuugo for his criminal actions.

Though he doesn't have a core partner, he maintains a team of Devimon; Meramon -> SkullMeramon; BlueMeramon -> Boltmon.


  • "Awesome McCool" Name: Or at least, in his opinion, because he keels with embarrassment when Reiko accidentally reveals his real name: Tanaka, a stereotypical "generic name" in Japan.
  • Berserk Button: Calling him out on being an obvious ripoff of KISS is one, even when Nokia fumbles on the name of it.
  • Catchphrase: "You pickin' up what I'm puttin' down?" (In Japanese, it's "Is it coming across? This feeling.")
  • Faux Affably Evil: He always acts like he's in a good mood, laughing all the while no matter what he's doing. This attitude usually drops when he loses of course.
  • Gratuitous English: In the Japanese version, he peppers his speech with tons of badly-conjugated and nonsensical English (the above Catchphrase has the word "feeling" in English).
  • Mass Hypnosis: With Rie's assistance, he uses subliminal messaging in one of his videos to hypnotize a bunch of fans into running away from home and coming to his concert.
  • Never My Fault: He blames his continuous battle losses on his Digimon not being good enough. Nokia calls him out on it.
  • Start My Own: After he's exiled from Zaxon, he and a few of their other bad apples form their own hacker group the "Demons".
  • Verbal Tic: He usually has a "lol" thrown into his words to play off his seemingly jovial nature.
  • Wake-Up Call Boss: Especially on Hard Mode; he's the first major boss the game throws at you that isn't defeatable within a few minutes and is capable of decimating your party.

The Specter of the White Boy

Voiced by: Ayumu Murase

A mysterious, phantom-like boy occasionally sighted around EDEN, who, according to Suedou, is the "physical manifestation" of Eater; his presence signifies that Eater is nearby.


  • Beneath the Mask: He constantly repeats that he doesn't want the others to come save him, because it's too dangerous and because it'll stop him from being a Power Limiter...but when the protagonist Connect Jumps into Mother Eater, they see an apparition of Yuugo's true feelings revealing him to have been feeling lonely and abandoned and wanting to be saved while the real Yuugo pleads with them not to listen.
  • Distressed Dude: The final battle of the game is a journey to the Digital World to save him.
  • Forgotten Childhood Friend: He is the forgotten friend in question; the incident regarding him caused Suedou to wipe his friends' memories to spare their sanity.
  • Heroic Sacrifice: He tried to hold off the invading Eater in the Digital World eight years prior to prevent it from reaching the other kids, and became the first EDEN Syndrome victim as a result.
  • Hive Queen: Although he can't directly control them, he's capable of seeing things and communicating through Eaters; even then, he has a difficult time doing so, and is only able to appear to the protagonist through a "memory fragment" he places in them at the start of the game.
  • Ill Boy: His consciousness is trapped in the Digital World in Mother Eater's core, leaving his body in EDEN Syndrome in the real world.
  • Power Limiter: He's responsible for restraining Eater as part of its core; without his presence, Eater is capable of going on a rampage, eating everything indiscriminately.
  • Walking Spoiler: As he's one of the most important characters in the plot, the number of spoiler tags in this section alone was inevitable.

King Drasil (Yggdrasill)

The "god" of the Digital World and the ruler of the Royal Knights. After Eater's invasion of the Digital World, it ordered the Royal Knights to investigate, but the unclear nature of its "will" left the Royal Knights split between interpretation over whether the solution was to destroy the human world or find another way.
  • Ambiguously Evil: It merely figured out where the Eaters came from and told the Royal Knights to investigate, whether or not it actually wants humanity destroyed or not isn't clear, as Leopardmon and the other evil Knights seem to have assumed it was.
  • Humans Are the Real Monsters: This is its "will", or, at least, if half of the Royal Knights are to be believed.
  • Lighter and Softer: Compared to other incarnations of Yggdrasil, anyway.
  • Master Computer: As per the tradition of the Digimon franchise, it's not actually a god as much as it's just a master computer running the Digital World.
  • Mercy Kill: The protagonists never fight it while it's bearing malicious intent, and by the time they reach its terminals it's pleading for help, so destroying them comes off as euthanizing them. The core entity survives, however.

    Introduced in Hacker's Memory 

Keisuke Amazawa

https://static.tvtropes.org/pmwiki/pub/images/hackersmemoryjp20th_4artbook_142hackersmemory.jpg
Voiced by: Ryota Asari

The Hero(?) of Hacker's Memory, his original EDEN account was stolen by a hacker, causing him to set up a temporary account, drawing attention and accusations of being a hacker himself. In order to clear up this mess, he seeks out the hacker who raided it, running into Ryuji Mishima, and subsequently joins the hacker group known as Hudie. He is given the choice of Betamon, Tentomon, and Gotsumon as his starter Digimon.


  • Badass Longcoat: What primarily marks him as a Hudie member is his long blue coat.
  • Beware the Quiet Ones: Chitose bluffs his way into intimidating the Steam Dealers group by pretending that Keisuke's super violent underneath his quiet demeanor.
  • Clear My Name: His initial motivation as he tries to find his original EDEN account and explain he's not a hacker to his school.
  • The Gadfly: Several of his dialogue options include provoking whomever he's talking to with playful banter, comments, or insults. Especially if Erika is concerned (after she's warmed up to him). He also likes to tease Yu from time to time.
  • Goggles Do Something Unusual: In a departure from the typical Digimon installment, his goggles are instead a VR headset that also functions as his Digivice.
  • Heroic Mime: The only times he ever speaks are in a few cutscenes and during battle. Dialogue choices and actions seem to indicate that he's got a strong sense of justice and a penchant for snarkiness.
  • Limited Wardrobe: Averted. Unlike Aiba, Keisuke has many different shirts and several outfits to choose from, and is capable of changing at nearly anytime.
  • Mistaken for Profound: Kyoko interprets his decision to make a silly face instead of striking a pose for a photo during her Shinjuku experiment as a reminder to take in all the factors for composing a photo when he actually just likes making that face for photos.
  • Ordinary High-School Student: A perfectly unremarkable student who hadn't gotten involved in any trouble before his account got raided.
  • Unwitting Instigator of Doom: Played for Laughs. Several cases end up showing that in one way or another Keisuke was indirectly responsible for the odd things that happen to Takumi/Ami, such as providing the ingredients for some of Kyoko's coffee or having provided the books that led Yuuko to assume a friend needs to act like an Emotionless Girl Tsundere.

Erika Mishima

https://static.tvtropes.org/pmwiki/pub/images/hackersmemoryjp20th_4artbook_144hackersmemory.jpg
Voiced by: Yui Ogura

A fellow member of Hudie and Ryuji's younger sister. Her brain is partially connected to EDEN at all times, making her incredible with information processing. Her Digimon partner is Wormmon.


  • Armor-Piercing Slap: Delivers an incredible one to Rie/Crusadermon on the Metropolitan Building rooftop, for demeaning human pain and suffering.
  • Agent Scully: She's highly skeptical of the various phenomena going on in EDEN and Tokyo and believes in examining all the evidence before reaching a conclusion. The one that really frustrates her is Mirei since she thinks of the rumors of Mirei being a witch are nonsense but her Digilab is unreachable by conventional means for her, Mirei casually blocks her from entering when she tries to hack her way in, and Keisuke's explanation doesn't satisfy her.
  • Fusion Dance: Happens to her twice. The first is when her Eater Bits turn on her, creating Eater Legion. During the fight against Eater Legion the final uncorroded portion of Erika's memory informs the members of Hudie that at that point her body has been completely lost and its death means her death. After being reminded of everything she wished to do with her life that fragment fuses with Wormmon to become Hudiemon, who proceeds to assist Keisuke in killing her former self, declaring that she's the "new Erika".
  • Hikkikomori: At the beginning of the game, she's basically confined herself to the VIP room of their net cafe. When she leaves for the first time, she mentions that it's been ages since she went outside and begins to slowly go out more and more as the game's story progresses.
  • Hive Queen: Toward the end of the game she manages to hack into an Eater and use the information to create her own small army of Eater Bits that prove necessary to defeat Arcadiamon.
  • Ill Girl: An accident earlier in her life left her with a condition where her brain gradually overloads and starts shutting down her body. The treatment is to essentially siphon out bits of her mind periodically and just store it in EDEN.
  • Insistent Terminology: She's not dissecting poor Wormmon, it's analyzing.
  • Rapunzel Hair: Her hair runs down nearly to her feet, kept mostly hidden by her coat.
  • Ret Gone: As history is being rewritten Hudiemon is left with the choice of returning to being Erika who will still suffer the accident that killed her parents and gave her her illness, or to remain as Hudiemon while the new world has no Erika which would prevent the accident from occurring, sparing Ryuji the loss of his family. She chooses to remain Hudiemon, and is only remembered by Keisuke in the new world.
  • Transferable Memory: Thanks to the method of treatment for her illness she's able to share basically everything about her mind with her Wormmon, making it her equal and able to fill in for her.
  • Tsundere: She often alternates between "hot" and "cold" when interacting with Chitose and Keisuke, and often is reluctant to admit her true feelings.
  • Unwitting Instigator of Doom: It was at least in part her accident and family's desperation to turn to a completely insane and experimental treatment that drove Suedou toward his plan to push humanity beyond the concept of sadness.

Ryuji Mishima

https://static.tvtropes.org/pmwiki/pub/images/hackersmemoryjp20th_4artbook_146hackersmemory.jpg
Voiced by: Yuuichi Nakamura

The founder and leader of Hudie, and Erika's older brother. His Digimon partner is Cyberdramon.


  • Berserk Button: Just seeing Arata makes him livid.
  • Big Brother Instinct: Very much so. Most of his actions seen during the game, as well as the ones mentioned to have occurred prior, are for the benefit of Erika.
  • Crutch Character: He often accompanies Keisuke on story missions during the first half of the game. Unlike the player character, who most likely has Rookies and Champions during this point, Ryuji is packing an Ultimate level Cyberdramon with infinite health and SP. Chances are he's going to be dealing much more damage to the opponent than your own Digimon will.
  • Face–Heel Turn: After watching Chitose being fed on by an Eater during the failed Under Zero raid, he is corrupted by the Arcadiamon trapped within the area. He thereafter serves as an enemy for much of the game, since Arcadiamon is forcing him to feed it the data of hackers and their Digimon.
  • Hunk: Compared to the rather lanky male cast, Ryuji is much more defined muscularly (which is accentuated by his tank top). Even Makiko Date is visibly flustered by him.
  • Instant Awesome: Just Add Dragons!: The Digimon he's personally raised all have draconian attributes, either in name or by design. Fitting considering his own Meaningful Name regarding dragons.
  • The Leader: He formed Hudie with Chitose after the failed Jude attack on Under Zero. He calls all the shots on Hudie's major cases, though he does occasionally defer to Yuugo's authority.
  • The Mentor: He teaches Keisuke the ropes of being a hacker and member of Hudie.
  • Mythical Motifs: All of his Digimon used are draconic in some way since his name is Ryuji.
  • Parental Substitute: Though he's Erika's brother, Chitose notes that Ryuji often acts way more like a dad towards her since he was Promoted to Parent several years ago after a car accident killed both of them.
  • The Stoic: He's pretty stern faced and serious most of the time, especially in the beginning of the game. If not for his occasional outburst every now and then, he'd take first place over Erika.
  • We Used to Be Friends: Was friends and teammates with Arata in the past. The relationship still remains a sore spot for Ryuji.

Chitose Imai

https://static.tvtropes.org/pmwiki/pub/images/hackersmemoryjp20th_4artbook_148hackersmemory.jpg
Voiced by: Yuki Ono

The sub-leader of Hudie and a firm believer in justice. He and Ryuji have been friends for a long time, founding the hacker group together. His Digimon partner is Ankylomon.


  • Bishōnen: He's very pretty, with soft facial features and longer hair, in contrast to the more rugged Ryuji and average Keisuke.
  • Casanova Wannabe: A lot of his spare time is spent trying (unsuccessfully) to hit on women. The only one he doesn't seem to be interested in is Ryuji's sister.
  • The Heart: With his generally cheerful attitude, he's the emotional glue that binds Hudie together. His influence on the team becomes much more noticeable after he is afflicted with EDEN syndrome, as Hudie begins to fall apart (both metaphorically and physically).
  • Heterosexual Life-Partners: With Ryuji. Together, they formed Hudie after the Judes disbanded, cementing his place as Ryuji's right hand man and close family friend. It's also a major reason why Chitose saves Ryuji from an Eater attack, getting afflicted with EDEN syndrome in his stead.
  • Information Broker: His role in Hudie as he gathers info for their missions through malware and social contacts.
  • It Was a Gift: The reason he ends up with a Shakkoumon? The Angemon that Hudie's internet cafe clerk gifted him, DNA Digivolved with Chitose's own Ankylomon. Also serves as an example of Gameplay and Story Integration.
  • Keet: Out of the mostly reserved Hudie, he's clearly the most energetic and excitable. He can also be very loud at times too-usually whenever he's passionately ranting about something.
  • Nice Guy: Very friendly, upbeat and easy to be around. Notably, out of all of Hudie, he's the only one to warmly welcome Keisuke into the group immediately. Ryuji uses this characteristic to his advantage, by having Chitose take care of Hudie's public image and relations. Furthermore, his explicit appreciation of Ankylomon is what allows it to DNA Digivolve with Angemon to become the much stronger Shakkoumon.
  • Put on a Bus: He's out of commission for several chapters due to being attacked by an Eater. Luckily, he gets better and comes back for the final chapters of the story.
  • "The Reason You Suck" Speech: Gives a lengthy one to Ryuji once the latter is momentarily free of Arkadiamon's influence. He doesn't skip a beat, telling Ryuji to stop feeling sorry for himself after all the crap he's done, namely: completely destroying Hudie's reputation, attacking countless Hackers and feeding their Digimon to Arkadiamon, destroying Hudie's building and center of operation, being a Jerkass to Erika, putting both Erika and Fei in the hospital, costing the woman Chitose loves her job, attacking Tokyo and other Japanese cities, being a danger to the public, and several other points. And this all comes after he's just recovered from the previously incurable EDEN syndrome.

Yu Nogi

https://static.tvtropes.org/pmwiki/pub/images/hackersmemoryjp20th_4artbook_150hackersmemory_3.jpg
Voiced by: Yuko Sanpei

Keisuke's best friend and the only student at his school who still supported him after his account was stolen.


  • Ambiguously Gay: His devotion toward Keisuke closely resembles that of Fei's toward Yuuko and at one point has Keisuke take him to various date spots, which he insists is just so he can make suggestions to a friend who asked for dating advice. Keisuke silently notes that Yu has no other friends beyond himself, but tagged along happily anyway.
  • Berserk Button: It's rather subtle at first, but it soon grows apparent that he does not like when Keisuke spends time with Hudie. Especially if it cuts into his own time with Keisuke.
  • Bishōnen: He may be even prettier than Chitose. The fact that he looks like a girl, has lilac hair, soft features, and frequently blushes only enhances this Trope.
  • Cannot Spit It Out: He blatantly has strong feelings for Keisuke, despite them not being clearly identified as platonic or romantic. Either way, he's never able to share them entirely with Keisuke due to either freezing up or being interrupted by someone or something.
  • Dude Looks Like a Lady: He is regularly mistaken for a girl, and this in turn leads to him being constantly bullied.
  • Hero Worship: He idolizes Keisuke for having saved him, constantly, from bullies and does everything he can to assist him in getting his original account back despite his complete aversion toward hackers.

K

https://static.tvtropes.org/pmwiki/pub/images/hackersmemoryjp20th_4artbook_152hackersmemory.jpg
Voiced by: ???

A mysterious hacker who claims to be the guardian of EDEN, protecting it from those who would bring it to ruin.


  • Ambiguously Human: Drops a few hints he might not be one at the start. Turns out he is, and any hints to the contrary were just a mysterious act. Except that he actually gets controlled by a digimon, so this might qualify as accidental foreshadowing on his part.
  • Big Bad Friend: His real identity is Yu Nogi, with his Hero Worship pushed straight into Yandere territory by a Matadormon hiding in his mask.
  • Cool Mask: Wears a white mask at all times. It's also an Evil Mask, being the hiding place of a Matadormon who's gradually driving him insane.
  • Dramatic Unmask: He sets one up to screw with you. In fact, he gets a few of these.
  • Herald: Sets Keisuke on his path by passing him leads on who stole his account, while fashioning himself as a kind of Trickster Mentor. Though as most of those leads turn out to be straight-up lies, Keisuke quickly stops trusting him in favor of other hacker allies like Hudie.
  • Inexplicably Awesome: The powers he starts showing later on - controlling his Digimon remotely, puppeteering other accounts, creating a cage around you that blocks logouts. Erika notes that it's very odd for someone with such powers to show up out of nowhere so suddenly.
  • Line-of-Sight Name: the hacker who calls himself K turns out to be a regular at the K Cafe.
  • Red and Black and Evil All Over: Wears predominantly red and black clothes, in contrast to Keisuke's cool blue. As for the "Evil" part, his actions increasingly become antagonistic to the player as the game goes on. Right down to ultimately being the culprit behind stealing Keisuke's account, siccing a SkullSatamon on a defenseless Keisuke, trapping him on EDEN in a manner similar to EDEN Syndrome and ultimately being the reason Keisuke has to fight an empowered Matardormon. And of course, this doesn't even count the other crimes he's done throughout EDEN.
  • Sanity Slippage: After the entirety of Tokyo is swallowed by a Digital Shift and hackers gain the power to alter the "real" world, he turns maniacal, starts rampaging with his Digimon, and encourages Keisuke to do the same. Of course before that, Matadormon was already twisting him. And by the end, Matadormon itself has become insane from the feedback loop.
  • The Man Behind the Man: Partway through the plot, he claims to be the real leader of the Demons, with Jimmy KEN as a front man. If this wasn't true originally, he does take over after Jimmy KEN's final defeat.
  • Yandere: He desires little more than to be Keisuke's best friend and partner. And he will do anything to accomplish that goal. He was the one to steal Keisuke's account and proceeds to send him on a wild goose chase consisting of other accounts he's hacked and controls remotely in order to make Keisuke rely on him, failing to consider that "K" is quickly proven to be untrustworthy while Yu is presented as timid and completely averse to interacting with hackers, which only serves to drive Keisuke to Hudie. When the world undergoes a Digital Shift he snaps completely, deciding he'll just become Keisuke as he can just bring the account avatar onto himself in the real world.

Arcadiamon (Arkadimon)

https://static.tvtropes.org/pmwiki/pub/images/arcadiamon_ultra_dscshm.png

A mysterious and very powerful Digimon that serves as one of the primary threats in Hacker's Memory.


  • Eldritch Abomination: One of the earliest examples in the franchise and you'd be forgiven for thinking that this thing couldn't possibly be a Digimon considering just how different it acts and looks compared to other Digimon. It's Ultra form in particular is ungodly in both appearance and power.
  • Generic Doomsday Villain: It doesn't have many aspirations beyond wanting to destroy and consume everything.
  • Knight of Cerebus: When it finally gets involved, things go downhill very quickly. Ryuji becomes its thrall, dozens of Digimon and hackers fall prey to its hunger, Hudie's workplace is demolished, and Erika is eventually assimilated by the Eater Bits she created in order to fight it.
  • Sealed Evil in a Can: The core of Under Zero that was protected by the Knightmon that beat down Jude was this thing's prison. Poor Ryuji ends up freeing it during his Heroic BSoD.
  • Olympus Mons: Any Digimon that reaches the Mega or Ultra levels qualify, but Arcadiamon deserves special mention as the first Digimon to ever achieve the latter form, and it has the power to back it up.

    Royal Knights 

As the Royal Knights primarily pertain to the second half of the game, note that this section contains unmarked spoilers.

A group of Digimon who serve under the Digital World's "god", King Drasil, and carry out its will. However, they're under dispute as to what King Drasil's will actually is; one faction believes that it wants to destroy the human world and Kill All Humans, while the other believes otherwise. As a result, the conflict between them becomes a major theme of the latter half of the game.

Although Digimon franchise lore establishes that the group was founded by Imperialdramon Paladin Mode, he himself does not appear in the plot, and shows up only as a Bonus Boss in the Royal Knights evolution-unlocking questline.

Omnimon/Agumon and Gabumon (Omegamon)

Click here  to see Omnimon
Voiced by: Chika Sakamoto (Agumon) and Mayumi Yamaguchi (Gabumon)

Nokia's partner(s), who initially appear to her as Agumon and Gabumon. Like the other Digimon in EDEN, they hail from the Digital World, but initially have amnesia as to why they came to EDEN. Nokia's strong will and determination allows them to digivolve back into Omnimon and recover his true purpose: save the Digital World from Eater.


  • Authority Equals Asskicking: He's a Royal Knight for a reason. As Agumon and Gabumon, he's not particularly strong or intimidating. After regaining his true form however, his power increases substantially. This is best shown with how easily he defeats Fei's party while simultaneously worrying the usually confident Yuugo-two of the most formidable and strongest hackers in EDEN at that time.
  • Big Eater: Agumon and Gabumon, to the point where they run Nokia's wallet dry trying to get them food.
  • Curb-Stomp Battle: As Omnimon, he dishes one out soundly to Fei after DNA Digivolving at Under Zero. It's even more notable because her party consisted of three Mega level Digimon, one even having a type advantage over Omnimon.
  • Fusion Dance: He functions as one harmonious entity as Omnimon, but has distinct personalities as Agumon and Gabumon.
  • Go Fetch: When attempting to stop Nokia from approaching Under Zero, Arata distracts WarGreymon and MetalGarurumon by...throwing a large chunk of meat for them to chase after. It works surprisingly well.
  • Sleep-Mode Size: The reason they appear as Agumon and Gabumon. Omnimon was forced to degenerate to Rookie form in the process of crossing over from the Digital World to EDEN; he didn't expect to lose his memories in the process. After becoming Omnimon, he still chooses to revert to Agumon and Gabumon occasionally in order to save energy for when the situation needs it.
  • What Would X Do?: Briefly contemplates what Nokia would do when wondering whether to take the risk of destroying the Digital Line point, as there wasn't any way to be sure of what would happen as a result. He concludes that she'd charge in before thinking and does so without hesitation.

Crusadermon (LordKnightmon)

Click here  to see Crusadermon
Voiced by: Aya Hisakawa

A dramatic and flamboyant Royal Knight obsessed with gracefulness and beauty, and one of the more vocal of the members of the Kill All Humans camp among the Royal Knights. Having inhabited Rie Kishibe's body in the hopes of infiltrating the human world, she's responsible for Satoru Kamishiro's murder.


  • Alas, Poor Villain: After everything Crusadermon did, Yuuko can't help but feel a bit sorry for Crusadermon as she passes, even calling her Miss Rie again.
  • Ambiguous Gender: Crusadermon had traditionally been considered a very effeminate male Digimon in the Japanese versions of previous works, but in this game is possessing the female Rie Kishibe. In the Japanese version of this game, Crusadermon's voice actress is female, and it's hard to be picky about human mediums when you can only pick from conveniently comatose bodies. Their Japanese speech pattern is gender neutral, but not as feminine as Kishibe's. Additionally, they specifically call themselves as the "king of Knightmon" in the Japanese scripts. The localization here refers to her as a female the exact same way the dub did for Digimon Frontier's "Crusadermon" before, unlike how Digimon Savers "Loadknightmon" was treated and voiced as male.
  • Dying as Yourself: Inverted; Crusadermon starts spouting out lines in "Rie"'s personality while dying as a way of taunting Yuuko.
  • The Heavy: While Eater and Leopardmon are the ultimate villains who must be stopped, Crusadermon is directly responsible for most of the events of the story, from corrupting Kamishiro from the inside to summoning the Royal Knights to the human world.
  • Humanity Is Infectious: Deconstructed. Crusadermon learned darker emotions like ambition or taking satisfaction in crushing those beneath you from inhabiting Kishibe's body and takes to them well.
  • It's Personal with the Dragon: While subservient to Leopardmon, it's ultimately Crusadermon that the cast has the most personal animosity towards, given most of the suffering they'd experienced up until then was Crusadermon's doing. Especially to Yuuko when she reveals that she killed her father.
  • Kill All Humans: Loathes humanity particularly more than the other Royal Knights and is especially fond of the idea.
  • The Mind Is a Plaything of the Body: Originally didn't plan to kill Satoru Kamishiro; his murder came about due to the combination of Rie Kishibe's ambition and negative feelings combined with Crusadermon's hatred of humanity and bloodlust. The whole "hatred of humanity" thing wasn't really helped by the experience of Rie's particularly nastier emotions.
  • You Killed My Father: Killed Yuuko's father.

Examon

Click here  to see Examon
Voiced by: Yuusuke Handa

A huge behemoth of a Royal Knight who ends up slightly corroded by Eater on his way out and ends up rampaging around. As he requires a huge amount of energy to fight, Crusadermon has to supply him with it.


  • The Brute: Examon's ginormous size and huge power makes him a huge towards humanity, but his lack of thoughts (and characterization) reduces his role to that of an occasional rampaging beast.
  • Mighty Glacier: His huge size comes at the cost of requiring tons of energy to function properly, and the protagonist and Arata manage to defeat him only when his energy supply's been cut off.
  • The Voiceless: He never does anything but roar, despite having a proper, credited voice actor; it's unclear whether his situation has cut off his mental faculties. He is noted to be bugged by all the Eater infections.

Leopardmon (Duftmon)

Dynasmon

Voiced by: Kouji Haramaki

A member of the Kill All Humans faction, and therefore classified as one impossible to convince to take the side of humanity. He believes strictly in following Leopardmon's and what he believes to be King Drasil's will, and that his own don't matter when it comes to his own actions.


  • Die Laughing: Dies claiming that he's doing so with his own beliefs without any remorse or second thoughts about his actions.
  • Undying Loyalty: To the point where he doesn't consider his opinion on humanity being particularly important as long as he carries out his orders. His own "beliefs" are simply those of his masters, leading into what he considers his "sense of justice".

Gallantmon (Dukemon)

Click here  to see Gallantmon
Voiced by: Yuusei Oda

Omnimon's friend, who, despite not entirely having trust in humanity, doesn't believe that it should be annihilated. Thus, he assists the protagonists in fighting off the Kill All Humans faction and helping them gather more allies among the Royal Knights.


  • Not Quite Dead: After Aiba has defeated Eater Adam, Arata is not only separated from the Eater, but also from Gallantmon whom he had devoured. However, Gallantmon is too weakened to help them out for the final mission.
  • O.O.C. Is Serious Business: Noted by Omnimon, he swore to never kill a human but was going after Arata worried about what he would become.
  • Vocal Dissonance: When he's introduced, he is said to have a "screachy voice", but his actual voice sounds anything like that. The description fits more in line with Masako Nozawa's performance in previous installments and it may be possible that she was originally intended to "reprise" her role as Dukemon, but couldn't.
  • The Worf Effect: Although he's played up as powerful by the narrative, he doesn't do much in-game, and he's primarily known by fans of the franchise to be an especially strong Digimon (particularly enhanced by his large role in Digimon Tamers). Thus, when he fails to lay a scratch on Arata and is eventually defeated and "eaten" by him, it's meant to show off how freakishly powerful Arata has become.
  • Worf Had the Flu: His actual defeat came after the first battle with Examon, where he was noticeably tired and hurt to the point Magnamon was worried about him.

His point of concern is over two young Digimon he'd seen be separated; eventually, the two returning to him and putting in good words for Nokia convinces him to take the case for humanity.


  • Authority Equals Asskicking: According to Kyoko, he ranks rather high among the Royal Knights. More specifically, he's a "leader" within their ranks.
  • Because You Were Nice to Me: Rather, because Aiba, Nokia, and Makiko were nice to his friends. Due to their kindness to Lopmon and Tokomon, Magnamon ultimately decides to fight for humanity, rather than assist the other Royal Knights in destroying it.
  • Blue Is Heroic: His primary color scheme is a heroic gold while his secondary color is an equally heroic blue. The imagery paves way for his eventual allegiance.
  • Chekhov's Gun: The mission of helping Lopmon find his Digimon pal seems inconsequential and routine for Kuremi's agency, at first. Turns out, that doing so later secures Magnamon as an ally for Aiba and his friends, as well as humanity as a whole.
  • Dishing Out Dirt: His attribute nature is Earth, interestingly.
  • Friend to All Living Things: Or at least to all Digimon, considering that his main worry is over two Rookie and In-Training Digimon. In regards to humanity, before Nokia returns them to him, he doesn't entirely know if they're good or not, and sides with them as soon as he feels there's a good case for them.
  • Grey and Gray Morality: Has this stance on the Eater situation, initially. He understands that humanity is responsible for the creation of the Eaters as well as the consequential destruction of the Digital World. It doesn't help that he's personally witnessed hackers abusing Digimon, in a manner akin to slavery, after his arrival in the human world. However, he's also aware that destroying another world for the sake of one's own isn't exactly morally correct or righteous-that would essentially be murdering millions of innocent lives. After Aiba's interactions, insistence from Omnimon, and learning about the newfound safety of his weaker friends, Magnamon ultimately chooses to forgo destroying the human world; he now fights against its destruction while trying to find a peaceful compromise for the situation.
  • Light 'em Up: One of his signature moves, Shining Gold Solar Storm, evokes this.
  • Pintsized Powerhouse: Most Mega level Digimon are several stories in height. The same holds true for the Royal Knights, especially in Examon's case. Magnamon is roughly the size of a human adult yet their equal in power and one of the highest ranking Royal Knights in this iteration.
  • Stone Wall: He's a defensive Digimon by nature: his highest stat is defense, one of his signature moves always increases his defense by 10%, and his signature skill has a 10% chance of reducing an opponent's attack damage by 75%.

Gankoomon

Voiced by: Tetsu Inada

A Royal Knight who's less interested in the whole schism or his opinion on humanity as a whole as he is in grooming his protégé, Hackmon, into becoming a Royal Knight. The protagonist ends up meeting up with him in Ueno and negotiating an arrangement in that he'll assist humanity if they train Hackmon - which is easier said than done when Hackmon doesn't seem to want the help at all.


  • Achilles in His Tent: Gankoomon has no desire to help with Leopardmon's plans against humanity, but doesn't bother to help the heroes combat it. His only concern is Hackmon's training.
  • Badass Arm-Fold: One of his default poses.
  • Hot-Blooded: His way of catching up with his old friend BanchoLeomon is...to start a spar with him. In addition, what gets him to initially listen to your request to help humanity is the fact he "likes your spirit".
  • No Indoor Voice: Gankoomon tends to shout a lot.
  • Sink-or-Swim Mentor: A particularly harsh mentor to Hackmon, as his final "test" to Hackmon is to defeat a BanchoLeomon. Ultimately, he does have Hackmon's well-being in mind.

Jesmon/Hackmon

Voiced by: Hiroko Emori

Gankoomon's devoted student in training to become a Royal Knight, who's lately been frustrated from the feeling of "something" restraining him. After coming to an epiphany about what it means to become a Royal Knight and defeating BanchoLeomon, he evolves into Jesmon, the thirteenth Royal Knight.


  • Declaration of Protection: The first step to Hackmon's epiphany is realizing that the purpose of a Royal Knight is to protect others, and thus he declares that he'll protect the protagonist when faced with BanchoLeomon.
  • Don't You Dare Pity Me!: His initial anger against Gankoomon and the protagonist comes from the fact that he believes Gankoomon is assigning the protagonist to train him from believing that he's so weak that he has to train with a human, of all things.
  • Goggles Do Nothing: Both as Hackmon and Jesmon he has goggles on his hood. These goggles in particular don't even seem possible for him to wear in either form, much less serve any purpose beyond referencing the series' preference for them.

Kentaurosmon (Sleipmon)

Voiced by: Keiji Hirai

A Royal Knight who's not interested in doing much but destroying everything, and whose speed is so overwhelming that only the Royal Knight UlforceVeedramon can match him in it.


  • Acrofatic: He's not fat by any means, but he's certainly bulky what with his armor, weaponry, and large six-legged frame. In spite of that, he's the second fastest Royal Knight bar UlforceVeedramon. It's also an example of Gameplay and Story Integration as speed is Kentaurosmon's highest stat and he keeps boosting said stat in battle.
  • Automatic Crossbows: While the rest of the Royal Knights either wield a sword (Omnimon, Crusadermon, Jesmon, Alphamon, Leopardmon, Imperialdramon Paladin Mode, and UlforceVeedramon), a lance (Gallantmon, Craniamon, and Examon) or use their bare hands (Magnamon, Dynasmon, and Gankoomon), Kentaurosmon stands out with its long-range crossbow.
  • Adaptational Villainy: This is the first time we actually get to see a Kentaurosmon being on the side of the antagonists. His case is especially notable; while Leopardmon, Crusadermon, Dynasmon and Craniamon had been antagonists in previous installments, Kentaurosmon was the only one of the nine Royal Knights that showed up in Digimon Data Squad who did not oppose humanity and instead fought with them together against his fellow comrades. Even in this case, this Kentaurosmon is mainly influenced by the human's negativity that is infesting EDEN, and unlike the other antagonistic Royal Knights, Kentaurosmon can be reasoned with.
  • Did You Just Have Tea With Cthulhu: After defeating him, what convinces him to cooperate is Rina taking him with her on a tour of the town.
  • Good Is Not Nice: He's a Holy Vaccine Digimon, yet openly antagonistic and supportive of the human world's destruction. He gets better though, but even then that's only putting it mildly.
  • Heel–Face Turn: After being defeated by Aiba and Rina and having his life spared by the latter, she and Kentaurosmon go on a tour to explore the world so he can finally have a clear opinion about humanity. After some sightseeing and visiting multiple restaurants, he finally joins the heroes after Duftmon and his entire faction is defeated.
  • An Ice Person: His signature move, Odin's Breath, involves using his Niflheimr to lower the temperature of the immediate climate while generating a blizzard. His other signature move is simply called Bifrost. This also applies to his character as he's very cold and distant, even after socializing with Rina and V.V.
  • Lightning Bruiser: When the protagonist initially encounters him, his speed is so overwhelming that they're unable to do anything; because only UlforceVeedramon can match up to him, and UlforceVeedramon is currently trapped between dimensions, this forces the protagonist to hop to an Alternate Universe and recruit Veevee. His armor is the second toughest among the Royal Knights, and he has the strength that surpasses that of many other Mega Digimon.
  • Not So Above At All: After having visited many restaurant with Rina, he asks her if they can finally do something different. He's annoyed by her foolishness, but in the end, he does admit that he's actually hungry.
  • Silent Snarker: You can meet him and Rina throughout several locations as you progress the story. Most of the dialogue is about them sightseeing and mostly visiting different restaurants. Kentaurosmon is either silent or goes "Hmpf". It isn't until Akihabara that he finally points out that they haven't been doing anything different.

Veevee (V.V.) the UlforceVeedramon (UlforceV-dramon)

Voiced by: Aiko Hibi

Rina's partner Digimon, an UlforceVeedramon from an Alternate Universe recruited because the main universe's UlforceVeedramon got stuck between dimensions. He initially appears as a Veemon after having his power stolen by Barbamon, but is returned to UlforceVeedramon form after the protagonist recovers it and joins the fight to save humanity.


  • Boke and Tsukkomi Routine: He's the tsukkomi to Rina's boke.
  • Lightning Bruiser: Because his speed can match up with Kentaurosmon, he's the only one able to help the protagonist fight against him.
  • Like Brother and Sister: Acts as sort of a responsible brother to Rina.
  • Super Speed: The fastest of the Royal Knights. It's his speed that's required to put a stop to Sleipmon's rampage.

Craniamon (Craniummon)

Click here  to see Craniamon
Voiced by: Yukitoshi Hori

A member of the Kill All Humans faction, classified as one impossible to convince to take the side of humanity. He is tasked by Crusadermon with supplying energy to Examon, which would therefore create Examon's Achilles' Heel.


  • Affably Evil: In his last moments, he admits that he's harbored second thoughts about hating humanity in the same way that Leopardmon and Crusadermon do and following King Drasil's orders, not wanting to believe that he was being disloyal.
  • Berserk Button: While willing to humor Suedou's questioning, Craniamon becomes furious and goes for the kill when Suedou mocks his fealty to King Drasil as having no will.
  • Extreme Doormat: He's only against humanity because of his loyalty towards his lord, and Suedou calls him out for Craniamon's lack of free will and thoughts. He does end up shaken by Suedou's words, has second thoughts about his loyalty and is then severely weakened by his doubt. He eventually gets a little bit interested in humans when he dies.
  • Famous Last Words: "Feh... What a hateful, yet strangely delightful existence you humans have. You are beyond my comprehension..."
  • Undying Loyalty: To King Drasil, to the point where Suedou calls him out for not acting as if he has his own free will. Suedou's words do end up creating doubts in his loyalty, which later ends up significantly weaken his stats and makes him vulnerable.
  • We Can Rule Together: Suedou attempts a lower-key version of this on him, asking if he could instead assist him in "evolving" the world instead of trying to destroy humanity. It doesn't work.

Alphamon

Click here  to see Alphamon
Voiced by: Maaya Sakamoto

The legendary "Knight of the empty seat" of the Royal Knights, who exists as a balancing factor for the Royal Knights - and, in fact, the true identity of the "Kyoko Kuremi" seen throughout the game, being an inhabitant of her body in the hopes of discovering the truth behind the Eater incidents.


  • Ambiguous Gender: As with Crusadermon above, Alphamon had typically been portrayed as male in previous franchise materials. Again, the convenience of a female medium are present, but it is notable that Alphamon and Kyoko-Alphamon have a slightly masculine speech pattern (though not exclusively male), while the true Kyoko speaks femininely.
  • Balance Between Good and Evil: Exists as a stabilizing factor for the Royal Knights, although "saving humanity" would probably verge on good in this case.
  • Cordon Bleugh Chef: The one responsible for "Kyoko"'s disturbing taste in coffee.
  • The Mind Is a Plaything of the Body: Kyoko's body has had such an influence that Alphamon is liable to start waxing philosophy or scientific speculation even in Digimon form.
