Characters: The World God Only Knows: Protagonists
The primary cast of The World God Only Knows
is actually surprisingly small and only encompasses four commonly-recurring characters. Two are humans and two are devils, though one of the humans is a little more.
open/close all folders
Keima is a 17-year-old student known throughout the internet as "The Capturing God
for his unrivaled mastery of Galge
. He vehemently claims to have no interest in reality or 3-D girls, instead preferring the company of his video game characters. Therefore, while a legend in the gaming world, in real life he's an anti-social otaku
whom most students avoid. Despite his lack of real world social skills, he demonstrates immense confidence and remarkable intelligence, and is in fact at the top of his class in every subject except PE
His life is changed completely one day when he unwittingly accepts a contract from hell that pairs him up with Elsea to capture evil spirits that are possessing girls in the real world. Using his vast knowledge and experience gained from playing hundreds of dating sims, Keima must win the hearts of young women in spite of his disinterest in reality.
At the start of the series, he's isolated
, rude, thoughtless and inclined towards abusiveness. However, as time goes on, he goes through some remarkably steady development and shows a surprising amount of concern for the girls he captures.
- Accidental Pervert: On a few occasions he'll accidentally stumble in on girls like Haqua while they're changing, though he rarely cares. Occasionally, though, he invokes his bad luck in this regard in order to finish a capture more quickly.
- Aloof Big Brother: To Elsie. His treatment of her is, at worst, Annoying Younger Sibling level.
- Anti-Hero: Keima is rude, antisocial and if left to his own devices he never would have begun the capture operations. However, over time, he grows invested in the work for its own sake as he grows to care more about the targets, making him more heroic over time.
- Ascended Fan Boy: Unknown to him, he is the epicenter of the Gal Game industry, to the point he and his site were responsible for the industry's re-invigoration while it was in shambles. Also he was asked to direct a game of his desire, but he refused in the end.
- Ascended to a Higher Plane of Existence: After overusing Conquering God Mode at the end of the first season, he is guided into the World of Dating Sim by various heroines. This is implied to be a hallucination or dream because he's still in Japan at the start of the second season.
- Asexual: Matters of romance and emotions aside, Keima has no sex drive whatsoever.
- Awesomeness by Analysis: Thanks to his gaming experience, he's able to deduce many key aspects of his targets and instantly become an expert at any board game. He also uses this skill in academics, by reducing the lessons to a few important key points and predicting test questions. Finally, this is what he uses to generally get the gist of whatever situation he's in, allowing him to plan his moves or make quick adjustments whenever his original plan starts to go out of track.
- Badass Boast: Keima is quite fond of these, from "I can already see the ending" to "I will end this capture in X days". They are not always true.
- Batman Gambit: The setup Keima uses to out Fiore as an agent of Vintage. He came up with it almost immediately after meeting her.
- Be Careful What You Wish For: During Kanon's capture he complains about her using stun guns. Fair enough, but then he proceeds to say that he wishes he could have a normal girl for a target for once. By the time the story gets to Chihiro being the capture target, he has absolutely no clue what to do since normal girls do not appear much in galge as main characters. Therefore, notwithstanding the eventual capture, he consistently fails to read Chihiro properly throughout the entire manga (See Break Her Heart To Save Her entry for further details).
- Berserk Button: Anything that questions his status as the Capturing God. Also, do not mock or harm Yokkyun in any way.
- The B Grade: Once has a minor breakdown because he gets a 99 on one of his tests. This is a justified example: he has a deal with his teachers that he can play games in class as long as he gets perfect scores.
- Big Brother Instinct: To Elsie, even though they're not blood-related. He'd deny it himself if asked, though.
- Bishie Sparkle: He can turn them on at will.
- Bishōnen: While he's usually a nerd, when pursuing a target and downplaying his interest in games, the fact that he's actually quite handsome comes to light. In the first novel, Yoshino Ikumi is surprised to see that he really is as handsome as her sister described.
- Break Her Heart To Save Her: Pushes Chihiro away after her confession to him because she isn't a goddess host and thus being close to him would put her in danger and get in the way of him finding Mercury. Regardless of the fact that she would want to be close to him. He obviously ends up very depressed afterward, enough to put him into tears over a real girl for the first time.
- Brilliant but Lazy: Subverted. Keima puts exactly as little effort as needed in anything that does not interest him… only said effort is just as much as needed to excel at such tasks. Particularly during capture operations, Keima sometimes withstands days and weeks of tedious menial labor just for the sake of setting up the needed scenario.
- Bunny-Ears Lawyer: Most of the teachers just ignore his playing while in class as he gets the best grades anyway.
- Butt Monkey: Everyone loves to beat on him, especially the girls. Justified, considering he can be a bit of a Jerkass to...well, anything that has anything to do with reality.
- Catch Phrase
- "I can already see the ending!"
- And (usually to Elsie) "Let me teach you something nice", with Art Shift to follow.
- 'Don't screw with me!'
- Appended to any statement about the way the world works: "...In video games."
- Character Development: In general, he's gone from a Jerkass to a Jerk with a Heart of Gold. Indeed, one way of looking at it is that he's becoming exactly what the ideal hero of the dating sim is supposed to be like: Kind deep down, brave, determined and self sacrificing. He's also become willing to put more time and effort into the captures as well as being less flustered when things actually go according to plan. Several of the arcs also have more specific development such as:
- Kanon's arc appears to have him skip the easy option of just being the person Kanon relies on and instead both making her grow up and allowing her to keep being an idol, which she genuinely enjoys. It's hinted later on in the Tenri arc that this kind of solution to the problem would have made an unstable, shallow love and reopened Kanon's gap, so it's a good thing that he had started to mature by that point. On the other hand, this does backfire about a hundred chapters later: It made her think Keima was just the observer type, causing her to hesitate too long to confide in him, which nearly got her killed.
- Chihiro's arc has him realize he couldn't just ignore the real world and pretend he's not part of it. Nor can he ignore the people in it and dismiss them as though he actually understands them. When the plot comes back to Chihiro, he also agrees with Ayumi that he is 'the worst' for how poorly he handled the situation, once again because he falsely believed he understood her. He ends up in tears because he had to hurt her.
- Jun's arc is the first time where he's willing to admit he actually cares about the personal problems of the capture targets. As he mentions in surprise to Nikaido, when he sees Jun upset for some reason he actually cares.
- Tsukiyo's arc has him abandoning his earlier behavior of not wanting to put himself in danger by leaping from a building and somehow grabbing her in midair. While Elsie was there to catch him, if she hadn't done that he would have surely died.
- He shows significant development in Akari's arc wherein he realizes living in an imperfect world isn't all that bad.
- Keima goes all out to save Kanon after she was stabbed. After meeting with Minami he also directly indicates both being greatly concerned for the girl's well-being while also slightly depressed that he has been forgotten.
Haqua: It's like you were rejected twice in a row after your conquests... Feeling sad?
Keima: It's good that she's forgotten... This way... She won't get involved in all this.
- Chaste Hero: Keima does not even raise an eyebrow seeing Haqua while she's taking off her panties.
- The Chessmaster: He's basically what Lelouch or Light would have been if they were into scoring chicks, real or virtual. Kind of comes with being a Magnificent Bastard. It's a package deal.
- Chick Magnet: In the Dating Sim world, there is no-one mightier than our Capturing God and it seems this has translated over to real life. Even when he's not trying to capture the girl like with Chihiro and Nanaka, he still gets them.
- The Chosen One: Keima is the most important part of New Hell's plan to save the world, and apparently the only one who could do the job.
- Consummate Liar: He's very good at pretending to be something else. Usually during a capture he has a completely different personality.
- Crazy-Prepared: Keima's P.E. teacher tries confiscating his PFP before swimming. Keima then brings out another one. The teacher takes that one too. What does Keima do? He takes out 6 more all at once. Even as a kid, he had 8 portable game consoles and 100 spare batteries. They even came in useful.
- The Cuckoolander Was Right: Mock his dating sim based strategies all you like, they work.
- Curtains Match the Window: Brown hair and brown eyes. He mentions briefly early on that in his school there's nobody with odd hair or eye colorsnote , meaning he's supposed to look normal.
- Dangerous Forbidden Technique: "Capturing God Mode"/"The God of Conquest Mode". Using it will burn out three years of your life an hour! ...or at least, that's how you'll feel afterward.
- Deadpan Snarker: Not a full part of his personality but he has his moments.
Yui: I'll teach you what true love is.
Keima: That's impossible when the couple is cross-dressing.
- Declaration of Protection: To Tsukiyo.
- Determinator: More so in later chapters.
Keima: There is always a chance of success! And if there isn't any... I'll just have to make one.
- Disguised in Drag: Does this a bit during the Heart of Jupiter arc.
- Distressed Dude: He plays this role with Yui and Mars as his Knight in Shining Armor in the horror house.
- Double Standard: Abuse, Female on Male: He is often on the receiving end of physical attacks by the girls. Were the roles reversed, he would be seen as a monster abusing helpless women.
- Enlightenment Superpower: His intense devotion and contemplation of games enables him to activate "Conquering God Mode." In this mode, he moves so fast it appears he has extra arms. If he overuses this ability, he will be drawn into the World of Dating Sim.
- Every Man Has His Price: Played for laughs, then forgotten by the next page, in the Yui recapture arc. Bifauxnen Yui is treating him like a weak girl, telling how she will protect him from bullying, carry him at their wedding, make him wear a dress... He is furious. But in a brilliant display of Genre Savviness she points out that if he married her, he wouldn't have to do any work, and could play video games all the time. All he can say to that is "... really?"
- Flash Step: He does this to Ayumi in FLAG 163. The scene is the current trope image.
- Forgets to Eat: Once he played 2 weeks' worth of backlog games for 20 hours straight yet did not eat. In the end he hallucinated and sang, then got woken up by Elsie who then lampshaded the importance of eating. It happens again later, helping spark off the Chihiro capture after she badmouthed him.
- "Freaky Friday" Flip: In the 9-chapter Yui arc the pair switch bodies. Even funnier is when he went over to the "dark side of gaming" and started to play Otome Games.
- Friendless Background: Played with. He certainly didn't have any friends, but that's because he didn't want any. When Jun sees him playing games alone at lunch, she assumes he must be too shy to talk to people.
- Geek Physique: He's at the top of his class, is the God of Conquest, but his body is rather frail because he forgets to get himself in shape due to his obsession with video games. During arcs that require him to be more physically active, he is frequently shown getting exhausted.
- Genre Blindness: While normally he's incredibly savvy, some situations just don't work if he recognizes an obvious situation. For example, failing to realize that in a Matchmaker Crush situation the actual target you're supposed to pursue is never who the matchmaker is pushing you towards. If he did realize this, the entire arc would fall apart or require a drastic resorting of how he considers relationships, such as properly recognizing Haqua and Diana for the Tsunderes that they are.
- Genre Savvy: He applies Fridge Logic from video games, and it works. Usually.
- A God Am I: Keima calls himself the Capturing God and conducts himself accordingly.
- Guile Hero: He's useless in physical confrontations, but thanks to his skill in strategy and seduction, pulls most of the weight in the series.
- Hates Being Touched: He doesn't like being touched, but he will allow himself to be touched if he has to.
- Heroic BSOD:
- Has a not depressing, but still severe (and kinda funny) one after realizing how feminine he has become while in Yui's body during her arc. It even got him into monologuing his "will"!
- Has a much more depressing and serious one, including a Bathtub of Angst, after he is forced to break Chihiro's heart after realizing she isn't a goddess' host.
- He tries to invoke this in FLAG 238 in order to dispel any thoughts on Tenri's part regarding the kiss between him and Kaori, but later falls into another serious one in FLAG 239 after bumping into Chihiro and Ayumi.
- Heroic RROD: Caused by exhaustion from trying to get 6 captures in 1 1/2 weeks. Fortunately, Apollo cured his exhaustion and cold.
- Hero with Bad Publicity
- He's referred to as Otamegane by numerous people. The nickname is a shortening of Otaku Megane. He's famous for being "the weirdest weirdo"
- He has to battle a different type of publicity issue when Kanon, a famous idol, confessed to him in the middle of the class. Later, he embraces this to get results as quickly as possible because people who still have their memories would think he's a two-timing jerk and get mad at him. Haqua calls him the worst of all men for his extremely manipulative behavior in this arc, though she shows she didn't really mean it moments later. Still, when that's what your biggest helper has to say about your plan then that's not a very good sign for your reputation.
- I Gave My Word: Although Keima wants to blow off helping Chihiro's band study, he did promise that if Chihiro or Ayumi ever needed him he would be there for them. He grumbles about how he shouldn't have said that since they weren't going to remember anyway but he did promise.
- I Know Mortal Kombat: It's remarkable just how well video games translate to reality for him.
- I Love You Because I Can't Control You: Dokurou/Nikaido thinks Keima fell in love with Chihiro for real because she's the only girl who never goes along with his expectations.
- Impaled with Extreme Prejudice: Fakes this in order to provoke a reaction from Dokuro in the Time Travel arc, but it costs him one of his four 'lives'.
- Insane Troll Logic: Unfortunately, insane trolls appear to run his universe, so he's usually at least pretty close to being right.
- In-Series Nickname: He has two; "God of Walkthroughs," or simply "God" in the gaming world, while his Real Life classmates call him "otamega".
- Instant Expert: He defeats Haqua at a game she brought from Hell that he has never seen before. She hasn't lost in the last 100 years. She doesn't stand a chance against God.
- I Reject Your Reality: He refuses to acknowledge the real world and chooses the game world as his ideal world.
- Irony: Of the situational kind. While his "conquests" have at least one Moe stereotype which allows him to apply his Dating Sim knowledge, the one person he confesses his true, unscripted feelings for is apparently the capture target whom he adamantly rejects for being so associated with the real.
- It's All About Me: Early on, he doesn't care at all about the problems of the capture targets and is only slightly concerned about Elsie.
- Jerk with a Heart of Gold: Keima can be very rude, insensitive and self-centered, especially at the beginning. After great amounts of Character Development, he still shows a tough demeanor, but has become a lot more noble and compassionate. He also has shown to care about Elsie and his capture targets. It goes to the point that he actually cries in regret over having to dump Chihiro, the first girl he began to treat as more than just a capture target.
- Large Ham: When talking to anyone who's not a capture target, usually Elsie. Especially if it's about games. Which is about 99.9% of the time.
- Like Brother and Sister: With Elsie.
- Logical Weakness: Three of them.
- First, ordinary girls like Chihiro or Asami with no clearly defined traits confuse him.
- Second, the energetic Cloudcuckoolander type like Tooru, since they operate outside logic and all of his technique is based on said logic.
- Third, aggressive girls like post-capture Yui. He plays games where he chases after girls. If a girl chases after him, he's as inexperienced as the next person and gets extremely flustered, something Haqua eventually picks up on.
- Loners Are Freaks: Eventually averted. He's just self-centered and mostly grows out of that.
- Love Triangle: There are two revolving around him at different points. In the first novel, he seems to do it as a sort of Self-Imposed Challenge, though the two girls in question rarely get in the other's way until Tooru sees him kiss Asami. Later and in the proper manga, there's a love triangle of Chihiro -> Keima <- Ayumi that becomes a huge snarled mess.
- Ludicrous Precision: Born on June 6 at 11:29 and 35 seconds and can memorize real-life events on minute intervals. He justifies this by the amount of memorization needed to complete video games on multiple arcs, so he has to have precision at maximum. Which makes perfect sense given the amount of time he has played his video games.
- Made of Iron: With all the physical abuse he goes through when exorcising, Keima is obviously like this, crappy performance in P.E. notwithstanding.
- Manipulative Bastard: He's very good at playing with the expectations and emotions of others, though generally for their own benefit.
At any rate, your plan sure is clever! The Goddesses want to quickly release their hosts. And in order to do that, they need Power of Love
. But with the current state of affairs
, only you can realize their dreams. There's no time to find new love. In the end, the Goddesses
have no choice but to accept you. Even if you are the worst of all men
. Not even the Weiss
can compare to you. You definitely are the worst sort of Big Bad Guy!!
- Master Actor: Keima is very good at putting on an act to get girls to fall for him provided they fit certain archetypes seen in dating sims. Even if the girls don't fit those types, he's still able to improvise very quickly. Haqua is briefly disturbed when she sees him immediately shrug off one such persona as easily as most people take off masks.
- Mate or Die: A G-rated example. He must conquest other girls to exorcise the evil spirits possessing them, and fulfill his contract with hell. An Explosive Leash makes sure he does not skeedaddle out of it.
- Maybe Ever After: With Chihiro. He may have received a rejection of sorts after confessing his love to her, but he later gets invited by her for tea.
- Meaningful Name: His first name Keima is derived from the term "gamer". It is also a homonym for Knight, a minor point for the Nanaka arc, referring to the "keima" shogi piece whose chess equivalent is the "knight".
- Megane: Justified; sometime in the last ten years, his eyesight deteriorated, requiring the use of glasses.
- Mental Time Travel: Happened to him in the "Heart of Jupiter" arc.
- Mistaken for Gay: Well, that's what happens when a Bifauxnen in a boy's uniform confesses to you in public.
- Nerds Are Sexy: The girls who like Keima for who he is have an element of this, though they also admire his strong will and disregard of the authority of others.
- Nerves of Steel: When his life is threatened, he never loses his nerve.
- No Guy Wants to Be Chased: He says that girls pursuing the main character are death traps… in games, that is. Later on, Haqua infers that he is weak against aggressive women.
- Nominal Hero: Early on, Keima is only capturing runaway spirits because if he doesn't his head will be removed. Character Development moves him away from this and by the time Kanon is stabbed he's explicitly doing it because he's genuinely trying to do the right thing, but it's not clear when he really reached that point.
- Nosebleed: We never see him show enough interest in girls to have a real one, but he can do it on command.
- No Social Skills: His vast experience of dating sims lets him play the suitor, but when it comes to befriending someone, he's at a loss. He's also incompetent when it comes to act like a concerned brother, though that's to be expected. As time goes on, his inability to read what people are really like leads to him getting more and more depressed since he doesn't know how to avoid hurting them.
- Not a Morning Person: Either from playing not enough or too many games.
- Not Distracted by the Sexy: Keima barely seems to notice all the fanservice around him, and when he does, he's usually annoyed by it. He even provides the current trope image, too...
Keima: Don't worry about it. I was deep in thought at the time, so I have no memory of your naked body.
- Not Himself: Yui in Keima's body creeps people out - she's too nice, which makes them suspicious or simply uneasy.
- Not So Different: Kaori accuses Keima of using and manipulating Tenri for his own goals, just like how she is countering with manipulating the young girl. After thinking on it, Keima realizes she's right and he is.
- Oblivious to Love: Even with Elsie, Haqua, and Diana constantly "bothering" him, he doesn't seem to notice they are head over heels in love with him. Not to mention the arc heroines who are hopelessly smitten by him. For those he does know about, he still ignores them, making it difficult to tell where this starts and stops.
- This is getting quite complex as the story develops, because he's at least becoming more involved with 'the real' and thus starting at least to react a little more to the feelings of others, including wistfulness that his capture targets don't remember him.
- Ominous Multiple Screens: To say that his Gaming Room is quite decked with these is an understatement.
- Ordinary High-School Student: A completely normal otaku student who one day is forced to capture evil spirits inside the hearts of girls.
- Panty Thief: He steals one of Ayumi's panties during her conquest in the Goddess Arc.
- Playing Cyrano: Played with when he tried to help Chihiro get together with the guy she liked at the time instead of trying to capture her himself. Unfortunately for Keima, she became interested in him instead.
- Proud to Be a Geek: He is obsessed with games and is very vocal about that fact.
- Reality Ensues: As Keima notes and uses to his advantage, when an idol confesses to you in real life as opposed to games good things do not happen. Instead, your peers now hate you.
- Real Men Hate Sugar: Keima has stated many times that he hates sweets, but if necessary for a capture will still eat them, as shown in Sumire's capture.
- Red Baron: Known to the game community as "Otoshi-gami"/"The Capturing God"/"The God of Conquest."
- Repetitive Name: His given name and surname have the same kanji as the first character.
- Resigned to the Call: Keima had to be blackmailed into helping Hell, and even then Elsie has to constantly nag him to keep working for the first half of the story.
- Ripple-Effect-Proof Memory: He retains his memories every time the Reset Button is pushed during the "Heart of Jupiter" arc, which is implied to be because he's carrying an orb. In chapter 267, he is also the only one beside Elsie herself who clearly remembers that she wasn't his sister prior to Elsie's retconning of reality.
- Sarcastic Confession: During the capture of Amami Tooru he confesses to having a deal with the demon Elsie where he kisses girls to save them from being eaten by demons. In context, this is something along the lines of him doing live action role-play.
- Second Year Protagonist: The series began during his second year in high school.
- Selective Obliviousness: Invokes this trope often. More particularly when Chihiro confesses to Keima and he pretends not to hear it. Of course it helps that Ayumi was there.
- Serious Business: Dating Sims.
- Shrouded in Myth: Chapter 51 shows just how muddled his reputation is.
- "Shut Up" Kiss: Performed on Chihiro during her capture.
- Single Tear: At the epilogue of the Goddess Search Arc, while ruing the fact that he had to reject Chihiro — his second to last capture of the arc, and his first and so far only aborted conquest.
- Smart People Wear Glasses: He normally aces all his tests.
- Speed Echoes: One of the applications of his Dangerous Forbidden Technique is to move his arms so fast it looks like many. In an omake, he takes it further and develops "Dancing God of Conquest Mode!!".
- Spit Take: When Elsie informs him that Yoshino Asami may already like him, he spits out his tea.
- The Spock: After Kanon is stabbed, the girls around him chastise him for not feeling anything, and approaching it like it's one of his games. However, it was shown that he knows just how serious it is, and that he's so determined to put things right, he's entirely focused on solving the problem and finding another goddess to help her before she dies.
- Spoiled Brat: He has 6 LCD TVs, 6+ home videogame consoles, 10+ portable PFPs, and a collection of gal games... in his own personal game library. And where does this all come from? Well, the "M funds".
- Stealth Insult: "Don't worry. I was deep in thought at the time... So I have absolutely no memory of your naked body." Needless to say, this doesn't exactly leave Haqua placated.
- Supreme Chef: Not exactly a chef, but according to the later chapters, he can make coffee that's to die for. Justified, as his family does live in a house with a coffee shop.
- Tears of Remorse: Cries at the end of the Goddess Search Arc, feeling regret over how he had to break Chihiro's heart when she was quite possibly the very first real girl that he actually developed true romantic feelings for.
- Teen Genius: Can predict test questions, remember events in his life to minute intervals, and multitask with ease, as shown when he plays multiple games at once.
- Terrible Artist: A Running Gag since at least the beginning of Kusunoki's arc, much to Elsie's amusement and Keima's chagrin.
- "The Reason You Suck" Speech: Delivers this to Kaori in FLAG 248 after having tricked her to reveal her "insurance policy" in case she gets tagged, and subsequently disposing of the same.
- Tsurime Eyes: His sharp eyes.
- The Unsmile: When he has to try to capture Sumire, he decides to work part time at her dad's ramen shop. When he fakes a smile, Elsie tells him that his eyes are dead but otherwise he looks good!
- Unwanted Harem: Has Haqua, Diana, Tenri, maybe Elsea and the Goddess hosts after him. The capture targets generally don't pursue him post capture, so they don't really count. In any case, it's really unwanted because all he wants to do is play his games.
- What Beautiful Eyes: His eyes occasionally attract a good deal of attention. Amami Tooru finds them absolutely beautiful while others like Nagase Jun find them striking and powerful.
- Subverted on occasion. For example in FLAG 70, when he put on a cheerful and diligent persona for Sumire the ramen girl (see The Unsmile above).
- When All You Have Is a Hammer: After finding out Kaori is working with Vintage, he decides to conquer her. When Elsie shows surprise, he admits it's not like he knows anything else to do.
- Wholesome Crossdresser:
- As the God of Being Captured when dealing with Yui.
- Also, during the Heart of Jupiter arc, when Vintage uses mind control to make all the girls lock the boys up, he cross dresses in order to blend in.
- Xanatos Speed Chess: A key tactic of Keima's, especially during the Goddess Capture arc where he pulls stunts like using the bad publicity from Kanon's confession to his advantage and using it in his plans or getting an overconfident Fiore to spill the beans about Vintage and let Vulcan know about the situation moments after assessing the situation with Haqua and Nora at her mercy.
- Yaoi Fangirl: He 'slips' after he is affected by the female body he occupies during Yui's arc. In his 'will,' he even calls himself a Fujoshi, or rotten girl.
- Your Approval Fills Me with Shame: Keima did not take it well when Kaori told him how they were Not So Different.
Elsea de Lute Irma
Also known as Elsie, Elsea is a low-level demon assigned as Keima's partner. Having served as a minor cleaning demon for most of her life, she's very inexperienced and lacking in confidence. She has a childish personality, is fantastic at cleaning and fixes food fit only for devils. She masquerades as Keima's little sister, but occasionally shows signs of having a crush on him. She literally idolizes Keima, often referring to him as "Kami-sama." She later becomes the left-handed bassist for Chihiro's band, the 2-B Pencils.
Over the course of the series, she has more or less graduated to being his real little sister. Apart from this, throughout the series she normally acts as a sort of plot device by using her robe.
- A Day in the Limelight: Chapter 255. After being Put on a Bus for the Goddess arc, and being mostly Out of Focus throughout the Heart of Jupiter arc, she finally gets a chapter dedicated to her that expands on her background.
- Amnesiac Hero: It is revealed she is the ultimate Weiss that Vintage and Satyr have been trying to summon and that Dokuro transformed her into a Devil and erased her memories to protect her from them.
- Angst? What Angst?: Keima's surprised Elsie talks about losing her parents and growing up in a Hellish orphanage so casually. She explains it's because she was young and didn't really remember anything, plus she had lots of friends in the orphanage. After regaining her true memories she calmly reveals to Keima that she is the weapon that Vintage and Satyr have been trying to summon.
- Annoying Younger Sibling: In all but blood. In the penultimate chapter she becomes his blood sister by retconning reality with her wish.
- Anti Anti Christ: The strongest Weiss, responsible for the destruction of millions over the years. But never by choice, or by intention.
- Attention Deficit... Ooh, Shiny!: She has an attention span of about 3 minutes. Becomes considerably shorter when she gets to see fire engines.
- Bad Liar: Though her lies tend to be believed, they're also quite spotty and generally default to something like 'Nii-sama is weird because he plays lots of games.'
- Becoming the Mask: In the role of Keima's sister. At first she called him Kami-sama ("God"), then Kami-nii-sama ("God-brother"), and now it's just Nii-sama ("Brother"). She also calls his mother "mother". She enjoyed it so much that she uses her power as the Ultimate Weiss to retcon reality so that she really is his sister.
- Big Bad Friend: Calls herself the "Final Boss.", and is the ultimate weapon that Vintage and Satyr have been plotting to revive. However, ultimately this is more an invoked term than anything.
- Big Brother Worship: One of the more literal versions.
- Book Dumb: Her English test score prior to Keima's tutoring is a miserable 18%. Afterwards... well, Ayumi, Chihiro and Kanon all get 100%, but Elsie only gets 45%, just managing to pass.
- Bumbling Sidekick: Keima has acknowledged that Elsie is basically completely useless as a partner.
- Butt Monkey: Elsie is only marginally competent and completely lacking in dignity, so if someone needs to be the butt of a joke, it's usually her.
- Can't Live Without You: Elsie and Keima share collars/chokers that dictate that if one dies, the other will as well, no matter what they die from.
- The Chosen One: Along with Keima, Elsie is at the center of New Hell's plan to save the world.
- Compulsory School Age: She transfers into Keima's class because her apparent age matches his and she needs an excuse to stay around him all day.
- Conveniently Unverifiable Cover Story: Poses as the illegitimate daughter of Keima's father, Keiichi Katsuragi.
- Cordon Bleugh Chef: Elsea may not be a bad cook by the underworld's standards, but humans aren't used to eating so many tentacles and other questionable "foods".
- Crouching Moron, Hidden Badass: Most of the time, she is a loser who can't even handle a few humans. However, when an agent of Vintage threatens her and Keima, Elsie manages to use her superior robe and some surprising ingenuity to defeat her.
- Cuddle Bug: She's very glompy and affectionate. During Haqua's first appearance, Haqua tries to pretend like they're not friends and acts pretty condescending. Elsie, on the other hand, doesn't care and just starts cuddling immediately.
- The Cutie: She's sweet, affectionate and silly, much to the contrast of the gloomy and sarcastic Keima. When she first shows up his classmates are baffled as to how he could have such a cute sister.
- Decoy Getaway: Leaves a number of robe dolls disguised as Keima to serve as decoys and distract Nora when she tries to kill them.
- Detached Sleeves: Her normal outfit.
- The Ditz: And cursed with enough self-awareness to realize it.
- Dude, Where's My Respect?: She currently has caught the most Runaway Spirits, yet her colleagues refuse to believe that a ditz like her could be so successful. Then again, Keima did do most of the work.
- Embarrassing Nickname: She is frequently referred to as the "Bug Demon" by Keima, in reference to how she is useless like a game full of bugs, and, like a stereotypical Demon, causes nothing but trouble.
- Emergency Impersonation: Keima gets her to impersonate Kanon after the latter is stabbed. That said, it doesn't fool Vintage as they leave her alone and kidnap the real Kanon.
- Epic Fail: She managed to set her notes on fire when studying for a test. When cooking she can demolish buildings. She also does that when cleaning if she's careless, but that one's a justified example since her broom is as powerful as a missile launcher.
- Expository Hairstyle Change: Lets her hair down near the end of the series in her new retconned reality.
- Flying Broomstick: She doesn't really need it to fly, but it does serve as her Magic Wand of sorts.
- The Glomp: Tries delivering these as a way of showing her affection, though her targets may dodge them.
- Hair Decorations: Though this applies to all the New Devil spirit catchers. Doubles as a spirit sensor. She changes it for a headband with a happy face accessory after her Retconjuration.
- Happily Adopted: Elsie accepts Mari's role as her Parental Substitute wholeheartedly, partly because of Becoming the Mask, and partly because she lost her birth parents at a young age.
- Hero-Worshipper: She looks up to Keima, Haqua, and Rimyuel, her onee-sama. She knows they're not perfect, but admires them all the same.
- Immortal Immaturity: She's 300 years old and still acts like she's 12.
- Like Brother and Sister: With Keima, though their relationship isn't without its Ship Tease moments. As of chapter 267, reality was retconned to make them actual siblings.
- Literal-Minded: When she tries to make a cake she puts it in a microwave-oven and cooks it by putting it over a fire instead of using its actual function.
- Little Bit Beastly: During a filler, she gets dressed this way as a bunny girl.
- Little Sister Heroine: Invoked and subverted. Elsie moves into his house by pretending to be his little sister, but the galge-obsessed Keima refuses to acknowledge her. Why? Because she doesn't fit all the cliches and just acts like a normal little sister. The relationship is not without its Ship Tease, but takes a distant place behind their primary relationship.
- Love Martyr: She deeply loves her Kami-nii-sama and outright states she would prefer to die than having him killed, despite the daily abuse and complete lack of respect. As Keima matures emotionally, he starts to treat her better.
- Magnetic Girlfriend: An invocation of sorts. Elsie's job requires needling Keima into making girls fall in love with him, but even when you put aside his new job there's still Tenri, Chihiro, Airi and Asami from the novels. Nanaka may count as well.
- Manic Pixie Dream Girl: Her job is to make Keima do a PG rated seduction, meaning he has to open up to others.
- Massively Numbered Siblings: Her parents were killed in the war, so she grew up in an orphanage with five hundred other devils. They all consider Rumyiel, the daughter of the orphan patron, their big sister. This turns out to be a fake backstory made for her by Dokuro.
- Meaningful Name: "Elsie" has multiple meanings, mostly dealing with God, such as: "My God is a vow"; "God is my oath"; "God's promise"; "Oath of God"; "God is satisfaction"; "Consecrated to God"; etc. Additionally, you can pronounce the name as "NPC".
- Meaningful Rename: After altering reality to become Keima's sister for real, her new name is Eri Katsuragi.
- Monster Roommate: She is a demon and lives with humans, the Katsuragi family.
- Mundane Object Amazement: She's a three-hundred year-old demon from Hell and is absolutely obsessed with Fire Engines.
- New Meat: Due to the sudden demand for Spirit Capturers, Elsea was newly assigned to her position without having undergone the usual rigorous training process. Or rather, she was assigned to her position after being reincarnated into a demon by Dokurou.
- New Transfer Student: She transfers into Keima's class at the beginning of the series.
- Otaku: Fangirls fire trucks to the point where she reads magazines about them and Kanon to the point that she's memorized Kanon's songs and choreography which comes in useful when Kanon gets stabbed and Elsie has to impersonate her.
- Out of Focus: As the plot goes on, she gets increasingly pushed into the background. She makes frequent complaints about this to Keima, saying that he treats her like an outcast and asking to be allowed to participate more, but Keima either responds that there is no choice or that she "doesn't have the stats for that".
- Parental Abandonment: Both her parents died during the Almage Machina, and she was raised at a Lifecare Institute in Hell. Or so it would seem. She never actually had parents in the first place.
- Playboy Bunny: During a filler chapter she gets dressed like one. The other cast members complain about how it's interrupting the story.
- Plot Device: In spite of being the main heroine, Elsie doesn't move the plot much and experiences little Character Development. Her main role is to listen to Keima's scheming and provide him with tools created from her robe.
- Pretty Freeloader: While she doesn't need to help out, thanks to her assumed role, she does help Mari with the house and cafe.
- Put on a Bus: For a protagonist, she has been away for quite a good chunk of the story. For the record, she left after chapter 117. She didn't come back for 40 chapters and only returned for her buddy role at the next act another 50 chapters later.
- Rapunzel Hair: Stretches down past her waist.
- Really 700 Years Old: Looks about seventeen, but is actually three centuries old. In truth, though, she's basically a high school graduate in devil terms.
- Relatively Flimsy Excuse: Poses as Keima's illegitimate half-sister. Chief Dokurou even prepared a letter "explaining" how it came to be.
- Retconjuration: She uses her power as the Ultimate Weiss to retcon reality, including her own existence. In this new reality, she's "Eri Katsuragi", Keima's blood sister and she never existed as a demon in the first place.
- Shoo Out the Clowns: Tends to happen whenever Keima gets serious about a capture. During the goddess search arc she's shooed away from even trying because she's replacing Kanon.
- Sidekick Ex Machina: Her role in Keima's strategies is essentially acting as a magic dispenser: "Elsie, could you do X with your robe?" "Yes, Kami-nii-sama!"
- Spell My Name with an "S": "Elsea" (as used in this Tv Tropes page) vs. "Elucia" (as per her Kaminomi Wikia page), nothwithstanding the fact that both sites eventually accept the nickname "Elsie"
- The series' character page on Wikipedia made it a bit more confusing as her name is spelt as Elcea de Rux Ima, but like the other two interpretations spells her nickname as is.
- The Southpaw: She is left-handed and plays a left-handed bass.
- Talking the Monster to Death: Rather than capture the Runaway Spirit by filling the gap in Rieko's heart (a return to her youth), Keima has Elsie explain to the Spirit that Rieko is far too old to bear children, the mechanism by which it would have been reincarnated. Realizing that Failure Is the Only Option, the Spirit surrenders.
- Tareme Eyes: Her round eyes.
- Time Stands Still: What she is capable of doing, as the Ultimate Weiss.
- Tomato in the Mirror: Her sudden disappearance is explained when Elsie reveals to Keima that she is the ultimate Weiss that Vintage and Satyr have been trying to summon, reincarnated into a Devil by Dokuro so that it could escape being used as a weapon and learn about love and friendship. Unfortunately, she's only able to tell this to him in a Mental World conversation after having regained her memories by being summoned back into her original form.
- True Final Boss: Refers to herself as such after regaining her memories and being reverted back into her original form.
- Unreliable Expositor: Quite a bit of what she tells Keima in the first chapter is... well, wrong at worst and only partially correct at best. There is a reason Keima directs most Hell-related questions to Haqua, even pointing out that he can't fully trust what Elsea tells him.
- Unskilled, but Strong: She's pretty much useless without her Celestial Robe, and other devils make it clear that she's not really that great with it, either. This becomes most relevant in the Heart of Jupiter arc, when they're stuck in the past, and all her magic and skills are ten years ahead of everyone else. Not only does she manage to cleverly defeat a Vintage agent, but the enemy apparently has no way of seeing through her invisibility, and she can even easily dismantle Vintage's master spell. This is because she is the Ultimate Weiss
- The Watson: Unfortunately for her, Keima isn't the best at explaining.
- Wholesome Crossdresser: In one of the illusory worlds Keima gets trapped in, Elsie is dressed in a boy's uniform because she is trying to fill the gaps in boys' hearts inside of an all boys school. Unless it was an outright Gender Flip.
- Zettai Ryouiki: Grade A in her school uniform and her RSS outfit.
Haqua du Lot Herminium
Haqua is a friend and former classmate of Elsea's and graduated at the top of their class, receiving the prestigious Scythe of Testament in recognition of her efforts. Having always excelled at everything she did, Haqua was quickly promoted to the position of District Chief of Area 32 in charge of capturing Runaway Spirits, but since her promotion she has had a terrible record. With the help of Elsea and Keima, Haqua wins back her confidence and in turn begins developing feelings towards Keima. Her human partner is Yukie.
Following this, apart from being used for Tsundere
antics, Keima seems to view her as both a more reliable source of information and occasionally a more competent partner to work with. Haqua later becomes Keima's temporary partner during the Goddess arc
due to Elsea being pushed aside at the time.
Keima's childhood friend who has just recently moved back into town. She has a huge crush on Keima, but because she lacks passion she's content to simply watch him rather than continue pursuing him.
She later plays a role in the third memory fragment of the Heart of Jupiter
arc where Keima pushes her into the spotlight to duel Kaori Yuuzaki as the number one female of Maijima East Elementary.
- Blinding Bangs: In her first appearance her hair was so long it covered the top half of her face with her eyes only peeking out on occasion. After that, she got a hair cut.
- Childhood Friend Romance: She has been in love with Keima since she was 7. Keima denies that they were friends in the first place, though. On the other hand (much like with Elsie after he used similar logic to attack her 'little sister' credentials), she ends up becoming one of his few actual friends.
- Color Failure: She looks like she got petrified. The OVA adds a Luminescent Blush on top of this, resulting in what looks like an intensely blushing statue of Tenri.
- Disappeared Dad: Tenri's father is not mentioned until FLAG 200 (10 years in the past).
- Extreme Doormat: She is very quiet, and Keima describes her as having no desires, which annoys Diana in regards to winning Keima's heart, but also leaves her immune to possession by the Runaway Spirits. Keima exploits this in the Heart of Jupiter arc by working to promote her to Alpha Bitch so as to defeat Vintage's scheme to create high quality hosts.
- Forgotten First Meeting: She used to be Keima's neighbor and classmate, but they were separated for a decade and he forgot about her.
- Girl Next Door: She's quiet, kind and submissive without quite reaching doormat levels.
- Hair Decorations: Has her hair tied into two braids and curved upwards supported by two large ribbons.
- Hopeless Suitor: Poor Tenri never had a chance to win Keima's heart because he was already meant to be with Chihiro and she knew it all along, but she still had a little hope that things could end up differently.
- Love Revelation Epiphany: While she was already interested in him, Kaori lying to Tenri about Keima being in love with her is pretty much what concludes with the development of Tenri's crush. Tenri is quite shocked when she realizes that Kaori tricked her.
- Meaningful Name: "Tenri" means "Rule of Heaven".
- Nice Girl: One of the nicest and sweetest girls in the cast. But thanks to Diana taking over she still ends up hitting Keima frequently.
- Patient Childhood Love Interest: She's referred to as one, but Keima vehemently rejects the idea by listing all the actual requirements for the trope. On the other hand, she doesn't take the initiative in her relationship with Keima despite having loved him for so many years, being glad with just being his friend and is a Girl Next Door living close to him. Justified because she needed to maintain a Stable Time Loop and wait until after his time travel adventure and she already knew they wouldn't end up together.
- Post-Kiss Catatonia: After Keima kisses her in order to trick Nora, she faints.
- Powers via Possession: As Diana's host. Before the confirmation that Diana is indeed a goddess as she claims, Keima theorized she could just be an abnormal Weiss trying to fool him.
- The Quiet One: Tenri says little. Most of the time Diana has to do the talking for her.
- Sailor Fuku: Her school uniform.
- Secret Secret Keeper: After Keima encounters her when they were in Elementary school and in order to stop Vintage, Older Keima must bring her in on the whole scheme. This was easy as Tenri had taken interest in Keima as they were both loners of sorts and so paid attention to what he did, but she was afraid of his cold personality. When Older Keima planned on returning to the future, it is revealed Tenri's memories were never erased and had known about the whole basic plot since her introduction in chapter 57.
- Shrinking Violet: She's very shy and quiet.
- Stage Magician: Tenri's hobby. She's particularly fond of the Disappearing Box. Diana is oddly fascinated by her tricks despite knowing powerful enough magic to split seas.
- Tareme Eyes: Her round eyes contrast Diana's Tsurime Eyes.
- Tarot Motifs: Tenri is the joker presumably because she's: A. not registered to Keima; B. did not have a Runaway Spirit but rather a goddess; and C. has overall different significance to the story than the other capture targets and Keima.
- Willing Channeler: Unlike the other hosts, Tenri invited Diana into herself, in order to save Keima and herself from the Weiss.
