open/close all folders
Team Triple Threat
A member (often considered to be a leader) of the team Triple Threat and the main character of the story. In the real world he acts as a diligent student always reading (or pretending to) some learning material and claiming that he doesn't know much about virtual games since he barely even watches TV. In Lost Saga his personality is a complete opposite of that image where he is loud, violent and selfish to the extreme.
A God Am I: After adjusting Yureka personality with a modified berserk spell during tournament states himself that he loves playing God. It bite him in the ass HARD when after match is over still blood-thirsty Yureka sensed his hostility and splattered him on the ring.
Always Save the Girl: In the latest story arc. By his own admission, he has nothing to gain and can't possibly salvage their relationship or be forgiven, yet he risks everything (including his own life) in a gambit to save Yureka.
He once tortured an enemy with a pair of nail clippers. But, they were trying to murder him...and it won't damage them in real life...and he was trying to help someone...so it's okay, right? ...But they could really feel it...and Lotto seemed to be enjoying it...
During the Tournament battle with Rapha, He started taunting her by burning her clothing off bit by bit, in front of almost all the players in Lost Saga. All because she called him a little runt.
Lotto: Hey, it looks like they're starting a fan club for you! You wouldn't want to disappoint them, would you?
Rapha: You can't do this!
Lotto: Watch me. Or close your eyes. Makes no difference.
The Atoner: His motivation for helping Mirenne after what he feels was cowardice dealing with Jaeha.
Awesome by Analysis: Prefers to keep things simple and blow up or fry his opponent with overwhelming force, but when facing someone stronger he is very adept at analyzing the situation, figuring out possible solutions and trying them out in a pattern that is most likely to bring him ultimate victory.
Disguised in Drag: Regularly conceals his identity on Lost Saga and comparative parts of the Net by logging in as Yureka. Not actually played up at all after the first instance.
Disproportionate Retribution: Beating people up for interrupting his train of thoughts, setting them on fire for the slightest insult (intentional or otherwise), or writing their name with their own blood (by using their body as a brush) for playing a prank on him. His personal life philosophy is the main page quote.
Pint-Sized Powerhouse: One of the strongest players in the game. And one of the shortest players in the game.
Playing with Fire: Lotto has a variety of spells at his disposal but fire magic is his clear specialty and usually the first thing used whenever someone pisses him off.
Raging Stiffie: He suffered from this after he walked on naked Jaeha, it caused him some trouble since the state of his body rendered the result of the body scan he took afterwards too embarrassing to use.
(note: Despite being created by Jaeha and sharing her looks Yureka is for the most of the story a completely separate person note At a certain point she is absorbed by Jaeha and from there onward they become one, with Jaeha being the one in control but with Yureka personality taking over most of her behavior)An advanced AI created by Jaeha as a copy of her own personality in order to serve as her double when she is on a missions. After mistakenly falling into Jang-Gun's hands and becoming used by him in the Lost Saga she was revealed to be a self-aware, fully sentient entity capable of feelings. Yureka's personality is somewhat childish, naive, curious and airheaded but at the same time kind and compassionate. She is very attached to Lotto and prefers to remain by his side, as well as her appearance in the game being exclusively attached to his (unless it is Lotto himself who uses her appearance).
A.I. Is a Crapshoot: a complete subversion, Yureka is actually one of the most compassionate and kind characters in the series often caring for others more than they do for themselves (due to the fact that player characters can't really die or feel pain in the game while Yureka do and is afraid of it). In fact in comparison to her many other players come out as Humans Are Bastards
Badass: Though mostly a pacifist in nature Yureka has one of the highest stats in the game which means that she can (and on occasion will) wipe the floor with master level characters
Badass Adorable: Physically more mature than most this trope is associated with but her innocent nature and cheerful attitude make her really cute.
Bitch in Sheep's Clothing: Yureka herself is as far from being this as possible but Lotto occasional take-overs of her body (without changing his way of acting) has convinced some players to suspect Yureka of being this and only playing innocent when around Lotto.
Jaeha in game appearances, either in her own body or by hijacking Yureka's, makes this impression even stronger and darker.
It is possible however that after they began sharing one body Yureka was this to Jaeha maintaining her own innocent image in front of Lotto while at the same tame trying to make Jaeha look bad to him and preventing her from coming out as much as she could.
Cloudcuckoolander: She occasionaly wakes up from this state making sharp and accurate observations but for the most of time she walks on her own separate path with the reality of the current events walking on another.
Mama Bear: No one hurts Lotto on her watch and gets away with it.
Mega Manning: As if her hacked stats were not enough, Yureka has the ability of instantly learning and mastering any ability that she sees. To make clear how strong of a talent this is it should be mentioned that other players need to spent a lot of time practicing those skills before they can use them effectively while she can do it better on her first try. Also though she mostly do this with the moves that are related to her class if she tries hard enough she can learn skills that should be completely unobtainable for a swordmaster.
Robot Girl: Cute as anything and totally digital. Deepens the story's theme questioning the nature of humanity and AIsand Lotto gets to show off his tall blonde escort.
Lotto's occasional usage of her body without changing his own way of acting may give this impression.
Yureka herself is created from a fragment of Jaeha's personality; the comatose Jaeha and Neogia can commandeer her visage the same way Lotto does, either taking over the body or cooperating in it together. Given that Yureka herself is not a human, it can be debated whether this condition is closer to being one part of a split personaliy or a Mind Hive.
Unskilled, but Strong: Yureka is very inexperienced as a player and often doesn't even understand what other characters are doing, all of her stats however are hacked and boosted to the absolute maximum making her faster, stronger, tougher and more agile than any player character (and most of the monsters) can hope to be
Lovable Coward: When he's not being its inverse. It's not infrequently that he's been known to hide behind a rock during a fight, but with team members likehis you can hardly blame him.
Mighty Glacier: His master level hammer's weight makes it glacially slow, but once it connects it can either deliver a massive damage to a single target or deal a wide area of damage.
Other Mainland Players
A companion and owner of John who she has a deep crush on, Rapha strongest characteristic is her complete devotion and protectivness towards her guardian, aside from that she is an emotional girl and is easy to provoke or burst into tears.
Yandere:Usually only deredere for John but God help you if you ever happen to kill her beloved or hold his life in your hands, Rapha will do ANYTHING to protect him and in the event this failed she would curse you for the rest of your life and made sure to remind you of it Every. Single. Day.
Bishounen: Surprisingly more so in real life than in the game
Disability Superpower: At one point discovered that remaining blinded for a long period of time allows the player to enhance his other senses to the point where they allow his perception to surpass sight in certain areas (while still remaining handicapped in others)
You Shall Not Pass: When during the defense of the Normal City United Guild Forces were annihilated and scattered he was pulling this off against the whole Demon Invasion Army until his example inspired other players to join him.
Shock and Awe: As a sorcerer he specializes in lightning magic. And is very good with it.
A younger ice mage who is introduced as a Jerkass using game loopholes to frame, rob, kill, and extort other players (with a particular grudge toward the ones that became famous during the city defense in the Demon War) in order to get money for his gaming fees. With time he gets quite some Character Development, initially thanks to tutelage from Lotto of all people, and later due to an extremely traumatic (and near fatal) confrontation with Jaeha that almost made him stop playing. Somewhat gets over his fears thanks to Phuan, who partnered with him (bullying him into it a little) and even pays for part of his gaming expenses.
Character Development: when he is introdused he comes out as a distilled 200%Jerk Ass and his actions are so low and despicable that the only reason the reader is following them is the hope of seeing him meet some ugly end, after that he is taken under Lotto wings and is straightened up a bit but his final and almost Face-Heel Turn change of personality came from nearly meeting an end too cruel even for him at the hands of Ax-Crazy Jaeha
Ice Person: As a mage Jijon Jang specializes in using ice magic.
Jerk Ass: Compared to him Lotto comes out as a saint, at the moment of his introduction (and for a long time after that) he acts on nothing but ambition, greed and jealousy.
Karma Houdini: Subverted. While he ends up as a somewhat likeable character despite all the evil things he has done he almost died before it by having a close encounter with an evil far greater than his own petty Jerkassery.
Loophole Abuse: Was very fond of using them to frame and kill other players.
Marshmallow Hell: Due to his small height and running without looking in front of him unintentionally given himself this with both Lotto-controlled Yureka and real-life Phuan, they both didn't thought much of it but he still was PK-ed by Yukera and mugged (and later kidnapped into teaming with her) by Phuan.
Running Gag: Whenever he talks back to Yureka (controlled by Lotto) a "- NOW LOADING -" screen appears informing us that he was just killed (again).
Bitch in Sheep's Clothing: During her travels with Jang and Crunade she was acting Ditzy and politely however once Jaeha kidnapped Jang and it was up to Mirenne to stall the pursuit she started acting like a brutal, foulmouthed backstabber.
Gender Reveal: While on the net Mirenne talks like a girl and looks very much like one it turns out that in real life she is actually a guy who learned how to hack his character data to make it look like a girl that he couldn't become in real life.
Kick the Dog: Was almost killed by the person s/he admired and trusted the most for no other reason than "I just have to kill someone and you are here"
One-Hit Kill: Her schtick is a low attack power countered by a high chance of striking a critical hit.
Team Healer: She is a priest so she can heal others. At least if they have enough time to wait for her low skill to do the job
The Mole: Was spying on Jijon Jang from the very begining on Jaeha orders.
Big Eater: Is eating something practically at all times.
Crouching Moron, Hidden Badass: A mild example - on the surface he appears as rather slow thinker but while it may or may not be true that he is not very fast he keeps thinking about the problem until he figures it out. He also apparently memorized tons of information in order to already have it on hand if the time is too short for him to figure it out by himself.
Mr. Exposition: Some key words (usually names of people or places) may prompt him into delivering a quick encyclopedia-like explanation about the topic at hand (whether the question was directed at him or even whether it was a question at all doesn't seem to be much of a factor in causing him to do this). This habit is at odds with his non-vocal behavior and sometimes makes other people surprised or even shocked.
No Social Skills: Is not very good at communicating with other peaople and usually prefers to follow someone else orders rather than participate in making a group decisions.
Stone Wall: His defense is so strong that it takes a lot of blows just to hurt him. His attack power, however, is very weak.
The Quiet One: Usually doesn't speak much keeping even his statements and responses as short as possible. Didn't speak for chapters after his introduction.
Alpha / Beta / Delta / Gamma / Omega (Wunha)
Ah-Dol's older brother and an acquaintance of Jang-Gun. He runs a Net cafe.
Aloof Big Brother: Alpha attempts to be unable to care less about his younger brother's actions, and when not drawn into bickering, threat exchanges and throat-tearing, succeeds admirably. Enough to irritate Adol, at least. He's been known to throw fights that were a matter of pride to Adol, much to the latter's shame and chagrin.
Crouching Moron, Hidden Badass: His in-game traits that stands out the most are his ridiculous behavior and non-existent naming ability which instantly blows his cover whenever he tries to pretend he is someone else (which is most of the time), despite that his knowledge of in-game mechanics is second only to the people from gaming companies (and not all of them) while his hacking abilities come close to those of a virtual killers. Similar in real life at first glance he is a cheerful cyber-cafee clerk who is often unable to control situation in his own shop but his knowledge of things ranging from inner workings of large companies to the existence of cyber-assassins is downright frightening and makes one wonder how and why is he amassing such wast amounts of information about things that normal people shouldn't know about at all...
Master of None: His diverse skill-gaining has prevented him from achieving master level in any single category.
The Fallen Angels / The Lovely Angels
In real life a pair of pop singers called the Lovely Angels, the Lee sisters are master-level thieves who use the Net as an escape, where they style themselves the treasure-hunting pair the Fallen Angels. Introduced as casual victims seeking revenge on the original Team Triple Threat, they are now uneasy allies with Lost Saga's other powerful players.Tropes common to the Angels:
Noodle Incident: Whenever Muria met Team Triple Threat, either she would get irritated by their presence or they would run away calling her "Medusa" fearing for their lives. It wasn't until the Invasion of the Demon King arc where the reason behind this was revealed: Before she was a GMPC, she kept a stable filled with monsters she collected until TTT randomly found and destroyed said stable for the EXP. Said incident gave her a Heroic RROD until she decided to try and get revenge on them for it.
Badass: After finding out that the Demon King was capable of regenerating from any wounds, all the players sent to fight him went on a quest to find the way to remove the source of his invulnerability. All except for Basara, who just hacked at Kast until he cleaved his head out and then dumped it into the lake, making it impossible for (still living) Demon King to reconnect with the rest of his body. His actions were so absurd and brutal that even the Demon King doubts that he is fighting a human and calls him "A Monster".
BFS: His weapon of choice is a gigantic two-bladed sword
Curbstomp Battle: Pretty much a walking one. Nobody has managed to stand up to him in a fair fight without hacking.
Companion Cube: Some of his behaviour may seem like this to normal players who can't see the spirit of his sword and thus assume he is talking to the sword itself
Determinator: Appears to run on raw determination. Once he sets something as his goal he will keep pursuing it no matter the obstacles, odds or whether or not outcome of succeding is something a sane person would want. He will achieve his goal or die trying and it does not matter how little sense it makes to others.
Robosexual: Before his defeat his raison d'etre was to fight strong oponents. After, the only thing that kept him playing the game was his desire to again meet and protect Faerlina - the StripperificArtificial Intelligence spirit of his sword.
World's Strongest Man: Widely acknowledged as the strongest player in Lost Saga. Later proves that this is incorrect and that he is fact the strongest being in Lost Saga, by winning a one-on-one battle with the setting's Final Boss.
NPC Amnesia: Whenever the game resets, so does Piri's memory of all non day-to-day events and players she's met. Actually culminates into something quite tragic, causing her to break down the second time it happens.
Mauve Shirt: Partially an in-universe example, as Lotto energetically protect her (which is to say he bullies Rowe into doing it—though Rowe warms to the cause—with Alpha stepping in now and then) from her unfairly hazardous surroundings (thanks to What Are You Looking At, she can't leave her shop, even if it's burning around her ears) during population-wiping events after being acquainted with her outstanding personality.
Promoted to Playable: She appears in currently untranslated chapters after her Despair Event Horizon in a capacity in which she appears to be acting as a player in the Lost Saga/Cyber Quest player tournament.
Red Shirt: Designed to be one in any big Event. Players decide this is somewhat unfair.
A guardian AI used by Rapha. He is silent, strong and fiercely loyal to his mistress to the point of being completely willing to die for her (to Rapha own horror), thanks to their cooperation and Rapha protective attachment to him he reached 94 level (which is almost unheard of for AI guardians that cannot respawn after death) and when buffed by his mistress he is more that a match for all but the strongest of players and monsters. Aside from being her assassin class companion in the game John also serves as her electronic assistant in the real world.
Killed Off for Real: Rapha greatest fear that many times brought her to a brink of emotional breakdown. Luckily so far due to his skills and her buffs, sacrifices and occasional intimidation of others he survived everything they went through
An NPC first introduced during the Demon War where he served as one of the Four Devas of the Demon King. Later, he reappears with different name as a player who took the top position in the Dragon Lands. It is revealed at some point that he, just like Yureka, is an advanced self-aware A.I. created by Jaeha.
Bad Ass: Was the toughest and most dangerous of the Four Devas and after appearing in the Dragon Lands he rose to a postinion of number 1 just by defeating PK'ers that challenged him (he for sure won against Jigo, Phuan, Sydus, Whan and most likely Ilban). If that was not impressive enough on it's own he was capable of completely overwhelming Elca in her full battle mode on her killer tool and the only reason he did not finish her few seconds into the combat was because she was unkillable and could continue fighting no matter how skillfuly and hard she was hit.
Perfect Play A.I.: The main reason why he was basically unbeatable during the Demon King arc and the Dragon Lands arc was that he could read a player's movement and counteract accordingly. Unfortunately, Elca found a way around this.
Curb-Stomp Battle: What he delivers to any and all that dare to fight back (not that he would spare them if they surrendered).
Deader than Dead: What happens to anything that is killed by any of his attacks (save from spells reflected from him), not only resurrection doesn't workj but even the data of the killed characters and NPC is erased from servers.
Hopeless Boss Fight: All attacks, both physical and magical, directed at him either do not do any damage or worse are reflected back where they came from, in turn his attacks are unblocable and can inflict damage even on targets that are supposed to be immortal and this damage cannot be healed or regenerated in any way, also anything killed by him is out of the game for good without the possiblity of ressurrection or respawn.
Enemy Mine: He was supposed to be the Big Bad of the Demon War, then DemonGod was unleashed and started indiscriminately killing everyone Deader than Dead forcing Demon King to forget about his role and ally with the players.
Pint-Sized Powerhouse: He looks like (and probably is) a kid in his early teens at most but despite that holds second rank among all the P Kers of Dragon Land and in terms of mastery of magic is stronger than either Lotto or Aradon.
Enemy Mine: This is her reason for making a team with Jijon Jang. He doesn't share her vievs (i.e. his terror of Jaeha far outweights any desire for revenge) but does not have enough courage to say "No" loud enough.
Expy: an unique example - Phuan is apparently modelled after the character the author of the manhwa plays as in Mabinogi
Jerk with a Heart of Gold: A mild example, Phuan comes out as more of a Blood Knight (in-game) and a delinquent bully (in reeal life) than an actual jerk but when analysed deeper she is a straightforward person that likes to fight but is not above helping others (going as far as to pay for part of Jijon Jang gaming expenses even though she barely knows him)
Animal Instinct: Even unconcsious she sensed "a terrible chill" that allowed her to sent Boromir flying before he got his chance to do a mouth-to-mouth on her.
Bad Ass: He is ranked 6th out of all the Dragon Lands PK-ers so this status is a given
Badass Bystander: Unlike most of the rest Dragon Land ihabitants he doesn't have a habit of picking fights with others and prefers to sit things out, this behaviour sometimes makes one forget that if dragged into conflict he can Curb Stomp any out of about 99.99% other players.
Boobs of Steel: Is one of the strongest (if not The Strongest) characters in Dragonlands in terms of brute strenght and has the biggest cup size (though it's implied that this is the result of "enchancements" bought with her husband's money and not her true appearance)
Breast Plate: Without a doubt chosen purposefully to emphasise her assets
Buxom Is Better: Remy certainly believes so and that is why she enhanced her own virtual bust size and selected Breast Plate as her armor of choice.
PKer from the Dragon Lands ranked 8th from the top; has a unrequited crush on Phuan, with whom he formerly partnered. He is a skilled programmer and developed and spread his own hack called "Checker," which allows its users to detect hacks used by other players. (His own version of that program also includes some other special anti-hacker functions.) Has a deep dislike of those who use hacks to cheat in game.
Ascended Extra: When he initially appeared he did not look like someone who will have any importance beyond current arc but then he started reappearung both in-game and in real world becoming more of a genuine supporting character
Black and White Morality: Heavily implied: he is a White Hat Hacker who hacks only for the benefit of players; Jang-Gun talks him into full support in a dangerous real life matter by saying that abandoning the project would be "against his beliefs," which Ji-Hoon ruefully concedes.
A Witch who act as an unofficial jury for ranking Dragon Lands Pkers
Chronic Backstabbing Disorder: While surprisingly a lot of the inhabitatns of the land of murderers adheer to a code of honor of some sort or another Iruhan is in the game just for the money and will sell out and betray anyone and everyone if it will be to her benefit
Xanatos Gambit: The outcomes of the fights she arranges are often win-win for her, as are the triumphs or losses of the people she leaks information to.
Three Black Stars: Daia, Omega, Goshu
Three PK-ers from Dragon Lands, each of them by himself counts as a rank A bounty but since they are always acting as a team of three the can be counted as a rank S bounty worth a total of 18,000,000 gold.
Butt Monkeys: They are actualy pretty strong and as a team could be ranked in the Top 20 of the Dragon Lands, unfortunately for them each time we see them they have a run-in with someone so out of their league that s/he doesn't even thinks of them as a worthwhile prey after mopping the floor with them..
Dunhil & Raison
Two PK'ers from Dragon Lands that sit on the beach waiting for any inexperienced newcomers to kill. While this appears to be a fairly succesful routine pretty much the only screentime they've got are the moments when they are trying their stunt on people they really shouldn't mess with (like Alpha, Yureka or Ah-Dol and Boromir) or just being handed the short end of the stick by a far more powerful PK-er (like Phuan) steamrolling over them.
Curb-Stomp Battle: They expected their fights with Yureka, Ah-Dol and Borimr, and earlier Aplpha to be short, while they were right about the lenght of the battle they were very wrong about who will be the one standing at the end.
Ax-Crazy: This never really was a part of her personality but she tried very hard to become this in order to earn Elca's approval. It did not end well.
Bad Ass: Her hacking and programing skills are on a whole another level even compared to Elca, the only thing making her less scary than her mentor was her inexperience with combat and emotional vulnerability that was preventing her from killing.
Becoming the Mask: Impersonating her unexpectedly prevalent AI has left her with some identity issues.
Berserk Button: Calling her "Yureka" is a good way of pissing her off, calling her "Fake Yureka" is a good way of getting killed.
Confusion Fu: Ban utterly dominated both Yureka and Ijoyen with his superior ability of predicting their moves by reading their minds (sort of, it was a little more comlicated than that) but the second Jaeha took over her movements became completely unreadable for him. Whether it was due to her superior knowledge of his ability (she was the one who originaly invented and programmed it) or the fact that her mind was too warped for him to comprehend was never explained.
Dark and Troubled Past: When Jaeha was still a child her family was driven into bankruptcy by a man who profited from crushing those weaker than him. Her parents, seeing no way out committed suicide, in which they tried to include Jaeha.
Despair Event Horizon: Was most likely balancing on its edge since the moment of her parents suicide but was ultimately pushed over it when in short succession she was rejected by the boy she loved because he liked her double more than anyone ever liked Jaeha, then was pushed by her bet with Elca to go over the Moral Event Horizon and finally faced the choice of either killing Lotto or giving up on becoming a Killer, her only goal in life. In the aftermath of this event Jaeha ended up half-comatose pretending even for herself that she is Yureka.
Freudian Trio: With her two artificial offshoots. Jaeha is the ego, Ijoyen is the very clearheaded superego (remember that Jaeha's conscious goal for a while was to quash her emotions), and Yureka is the impulsively friendly id.
Friendless Background: For a very long time the only person she was close with was Elca but they were both too broken to openly form a frienship (and almost ended up killing each other despite being aware of how important the other one is to them), then she met Lotto and ended up being fascinated with him only to be informed that he not only is not interested in her but also doesn't want to see her ever again note though in his defense it should be mentioned that he had no idea that the one he was taliking to was a real person desperately trying to connect with him and not a freshly created A.I. trying to take Yureka place without having any previous relationshipn with him whatsoever. When Elca lead Jang-Gun into Jaeha apartment she commented that he is probably the first guest ever to come there.
Moral Event Horizon: Attempted to cross one in order to prove herself to Elca but it destroyed her both emotionaly and mentally along with almost getting her killed.
Naked First Impression: The first time Jang-Gun met her he walked into the room where she was taking her scan in the nude, surprisingly enough it was Jaeha who seemed amused by this while Jang-Gun was the one really embarassed.
Replacement Goldfish: Tried to become this to Lotto by pretending she is a rebooted version of Yureka (after she destroyed the original) but Lotto rejected her because he was only interested in Yureka and not her look-alike.
Split Personality: Once Lotto connected with comatose Jaeha's consciousness he discovered that after going through Despair Event Horizon and passing Moral Event Horizon Jaeha started not just acting like Yureka but also actually beliving that she is Yureka and attempts at making her realise and admit who she really is are only making her withdraw even deeper to the point where she shuts herself off completely. To make things even more confusing supressing Yureka did not make Jaeha want to come out of her mental shell but instead revealed that there is a third personality - Ijoyen. At this point it is difficult to say whether the connection to the net caused both of the A.I. created by Jaeha from parts of her own personality to return their experiences to her and causing this dissorder artificialy or whether those are actual parts of Jaeha own personality note which were initially used as a base for creating Yureka and Ijoyen that manifest themselves while she is unable to cope with her own identity.
It may be worth mentioning that Lotto pointed out that all thre of those personalites are importnant parts of a single whole, however even though Lotto started to come to terms with it and was ready to accept Jaeha with all of her personalities "Jaeha" herself is unwilling to accept his feelings if they are directed at both her and her "Yureka" persona at the same time and the feeling is mutual on "Yureka" part (no one seems to care about Ijoyen).
Stalker with a Crush: Depending on how you interpret her actions she may be eiher a very tragic Broken Bird whom only hope of salvation from the darkness comes from unrequited love or a very creepy stalker note Lets's see, her interest in Lotto started with watching him play with Yureaka and it appears that Jaeha was recording their journeys so even if she was busy with something else she could enjoy watching every in-game moment later on, then she effectively killed Yureka, attemoted to take her place and finally when she realised that Lotto was interested only in Yureka and not her she intended to kill Lotto friends but spare him and give him Yureka program as a reward for his "inaction" in order to make him delete her himself out of the sense of guilt
Teen Genius: As a first (and possibly the only so far) person in the world she invented a method to create True A.I. and she done it all by herself.
Assassin: She is one of the hackers known (to those few that are aware of their existance) as Killers and Hunters - Killers are people who perform their kills by attacking victims in virtual reality (and making real body die from hypnotic suggestion or enough pain induced trauma), Hunters are those who act as bodyguards and avengers against killers (and use the same methods to fight). Both basically do the same and so whether one is at any given point of time a Hunter or a Killer depends mostly on who is paying them and for what.
Ax-Crazy: In her battle mode literaly crazy and to a frightening degree.
Ax-Crazy: When she's using her Killer Tool. It eliminates the threat of pain, but completely saps her self control as a side effect.
She uses her Killer Tool to change which area of the brain is affected by an injury and feels pleasure instead. If you combine this with the fact that only pain can affect her actual body this makes her not only completely Ax-Crazy but also, to an extent, immortal.
Bad Ass: While majority of the cast count as this only as a game characters Elca is a real assassin and is considered to be one of the top three in the country.
Break the Cutie: Once Jaeha started to recover some of her cheerfulnes by watching Lotto Elca gave her several pushes that sent her friend down the slippery slope right into the jaws of Despair Event Horizon. (Granted, this was the last thing Elca wanted but the fact remains that once events were done with her Jaeha was in a coma, convinced that she became a mass murderer and was using her Split Personality to hide herself from everyone thinking that no one would accept her now).
Combat Sadomasochist: Her Killer Tool converts pain, meant to deter killers, into pleasure, so much so that it functions like a drug.
Death Glare: Once she becomes serious she often throws one around, also it seems that Lotto is very adept at earning this (and worse) by unintentionaly pushing her Berserk Buttons.
Nice Job Breaking It, Hero: Elca put Jaeha to a Cross the Moral Event Horizon test in order to make her realize that the job of a Killer really isn't for her, unfortunately while she guessed her friend emotional vulnerability right she misjudged her equally strong desperation to become one and as a result Jaeha became completely unhinged and went on a random killing spree only to realize the gravity of her deeds and choose Heroic Sacrifice (sorta) option imediatly afterwards.
Nigh-Invulnerability: To kill someone for real in virtual reality you need to use hack that makes them feel pain and then inflict enough of it to make their body die from trauma. Whenever Elca suffers an injury in her battle mode she feels pleasure instead...
The Tease: After she invited Jang-Gun to Jaeha house she stripped herself and taken a shower, though it's hard to tell whether she has done that in order to make Jang-Gun squirm or simply because she had not cared about the situation (In which case it could be counted more as her lacking in social skills).
A low-level worker for Dexon and friend of Wun-Ha's, he skirts just close enough to the serious Corrupt Corporate Executives to act as an inside source.
The Faceless: his face is always hidden in shadow, unlike most other users of this trope he appears to have his face somwhere dim (like under the table) for the sole reason of having his dauther lash out at him for being a madman. Funny thing is (for the reader) that he doesn't do it on purpose, sad thing is (for the father) that he doesn't do it on purpose...
