Characters: Haiyore! Nyarko-san
aka: Nyarko San
These are the characters of Nyarko-san
that crawl up to us with a smile!
An energetic silver-haired girl who happens to be an anthropomorphized form of the Crawling Chaos, Nyarlathotep.
A 17-year-old high school boy with a fascination for the Cthulhu Mythos
- Action Survivor: He's been in close contact with the denizens of the Cthulhu Mythos... and he's still not insane.
- Actor Allusion:
- In episode 8, Nyarko warns him that, unless he is careful in dealing with his coworkers, a beautiful girl with a katana may cut him off.
- In Episode 9, he (in Nyarko's body and voiced by Asumi) says "I'm so stupid."
- In episode 12 of W, a drunken Cuune makes reference to Dream C Club, quickly adding "But I won't chose the inventor girl with the Kyoto accent!"; said character, Mio, is voiced by Eri Kitamura, serving as a nod to Cuune's hatred of Mahiro.
- Adaptation Dye-Job: Has black hair in the light novels, which gained a dark brown tint in the anime.
- On a similar note, his eyes went from brown in the novels to grey in the anime.
- Ascended Fanboy: Though in this case it's an extremely mixed blessing.
- Aww, Look! They Really Do Love Each Other: When Ato-ko shows up in the novels, she puts Mahiro in a fantasy sequence to determine who he really loves — and we get an Imagine Spot of him and Nyarko getting married.
- Likewise, when Nyarko confesses her feelings in front of her parents, Mahiro simply turns bright red instead of getting freaked out like usual.
- Badass Normal: On the rare occasion that he gets to fight, he holds his own with nothing but a fork.
- Empowered Badass Normal: Though the novels later reveal an ability to perceive fluctuations in spacetime and a much higher than normal resistance to You Cannot Grasp the True Form. Together with the curious appeal he has to the series various aliens that first kicked off the series, it hints he might not be entirely normal after all, especially given his parents established connections to the eldritch world...
- Beware the Nice Ones: He may seem to be a hapless boy, but push him too far — especially make fun of the Cthulhu Mythos — and he will stab you with a fork... whether you're human, animal or Lovecraftian.
- Berserk Button: Never ever malign the Cthulhu Mythos.
- Bishōnen: Handsome enough to have smitten Nyarko just with his photo, get "scouted" for a role in an alien boys' love show (he was not pleased with this), and get confessed to by Hasta. At one point the girls tell him that he's strangely attractive to aliens.
- Brutal Honesty: Tends to be very direct with his thoughts about all the Lovecraftian insanity around him. In one case, he even made Nyarko lose almost all her SAN Points by directly telling her that he doesn't like her.
- Can Not Spit It Out: In episode 5 of Nyarko-san W, he mutters to himself that he'd probably be more interested in Nyarko if she wasn't so manic; he actually says this in Nyarko's presence, but refuses to repeat himself when she says "What did you say?".
- Can't Act Perverted Toward a Love Interest: In the wake of his body-swap with Nyarko he can't even find the courage to look at the latter's naked body while taking a bath.
- Catch Phrase: He has a couple: "Wait, that makes no sense"note , "That was another stupid ending" and "Keep it to three lines"note
- Color Failure: The poor boy is prone to this, be it for failed SAN Meter checks or having his mom returning without warning.
- Crazy-Prepared: Be it forks to fend Nyarko off or a cellphone with camera with which he can blackmail her into doing her job properly. He takes this to another level in Episode 7 of Season 1, where he's got enough forks to pin Nyarko to a table for the whole night after she tried to make their "love take form".
- Crossdressing Voices: Eri Kitamura is more used to younger girls and kids, not a boy in his mid-teens like him.
- Averted (kind of) during Mahiro and Nyarko's "Freaky Friday" Flip and Kitamura gets to "play" Nyarko.
- Cry Cute: A male example (albeit in Nyarko's body) when he thought Nyarko (in his own body) died shielding him from the Star Child Guardian, admitting that he should've been far nicer to her. Of course, that was Nyarko's setup to give him a really deep French kiss.
- Did You Just Subdue Nyarlathotep With Forks?: Roughly Once an Episode.
- Did You Just Get Nyarlathotep To Fall For You?: He did; he might consider it unfortunate (for now), but some fans tend to think he's an idiot for being less-than-receptive to the hot silver-haired geek girl who totally wants to play Adam and Eve.
- Disappeared Dad: His father's alive and well, but he has yet to appear in either the novels or the anime. It's implied that he's stuck at work almost constantly to make up for all the honeymoons he goes on with Yoriko.
- Even the Guys Want Him: Just ask Hasta.
- Friend to All Children: His interactions with Guthatan, Hasta, and the human-ized Shanta-kun show that he's quite fond of kids. He's even admitted to viewing Hasta as the little brother he never had.
- Generation Xerox: He inherited his fork-wielding skills from his mother Yoriko.
- Genre Savvy
- Being well-versed in the Cthulhu Mythos, even though he certainly likes Nyarko, he's at least aware that dating an Eldritch Abomination isn't exactly so great an idea, explaining his mild Tsundere attitude.
- He also got Cuuko off his back by exploiting her Psycho Lesbian crush on Nyarko to win her over as a mutual ally.
- He's actually developed to the point where he attempts to spot the Foreshadowing in advance, mostly by asking "What would make for the dumbest resolution?" So far he's only been right once (in episode 9 if Nyarko-San W); the rest of the time he's wrong because something comes out of nowhere and results in an ending even dumber than he anticipated.
- Wrong Genre Savvy: Partially. He thinks he's a Player Character in Call of Cthulhu. He's actually in Teenagers from Outer Space, albeit with heavy Call of Cthulhu themes.
- As noted above, Mahiro's heel-dragging over his feelings for Nyarko comes from the fact that he's always afraid she'll turn out to be a malicious manipulative monster just like the Lovecraftian Nyarlathotep who's just messing with him. If he realized he was in a Lovecraft Lite Rom Com and that Nyarko actually is in love with him, he'd probably be a lot happier. She is driving him insane, just not in the way he's thinking.
- Gratuitous English: Courtesy of episode nine's introduction. CLOSE. YOUR. EYES.
- Improbable Weapon User: When he has to, he fights with his trusty... fork.
- Kid With The Fork: He does his best to keep Nyarko's, Cuuko's, and, sometimes, Hasta's antics under control.
- Luminescent Blush: Mahiro gets one after seeing Nyarko's panties, and also when he takes one of her advances seriously — sometimes Played for Laughs.
- At the very start of the story, he gets one at the idea of having a pretty girl like Nyarko being around him day and night; when she notices and calls him cute, out comes the fork.
- In the novels, he gets one during his first meeting with Nyarko's parents when she she tells them that she's in love with him.
- Nice Guy: He is legitimately a good, caring persion; he just has a short temper when it comes to Nyarko and co.'s madcap antics.
- No Guy Wants to Be Chased: There's a reason Nyarko gets a taste of Mahiro's fork rather than a taste of...something else of his.
- Non-Action Guy: Not that he can't hold himself in a fight, but when he has Eldritch Abominations chasing after him, he'd be powerless without Nyarko, Cuuko and Hasta rushing into his defense.
- Not So Above It All: In episode 3 of Nyarko-San W, it turns out that he was the one carrying the mystical book that the villains wanted; he has a Big "NO!" and Nyarko complains about how mean and hypocritical it was for him to try and pin this one on her. He defends himself by saying that that's usually how it works, only for Cuuko to call him out for making excuses.
- Only Sane Man: What he is desperately trying to remain.
- Opposites Attract: With Nyarko.
- Ordinary High-School Student
- Peek-a-Bangs: Has the shy version in almost all the light novel artwork by Koin.
- Ripple-Effect-Proof Memory: He has the extremely rare ability to perceive and resist shifts in the space-time continuum; this gets brought up in the first novel when dealing with Nodens and Cuuko, but becomes a Chekhov's Skill later when Nyarko and Cuuko get written out of existence and Mahiro is the only one who can save them. Considering the series' love of Kamen Rider, this may well be a Shout-Out to the concept of Singularity Points from Den-O.
- Savvy Guy, Energetic Girl: Savvy Guy to Nyarko's Energetic Girl.
- Second Year Protagonist: And he's seventeen. We know because Nyarko has No Sense of Personal Space.
- So Beautiful, It's a Curse: To the viewers, he looks like an ordinary but still cute anime boy; to the aliens of the Cthulhu Mythos, he's apparently sex on legs, which means he's been scouted for a Boys Love TV show, had a Yaoi Doujin written about him, and keeps having aliens fall in love with him.
- Straight Man: With Nyarko, you'd have to be.
- Took a Level in Jerkass/Took a Level in Kindness: An odd example; comparing Nyaruani to the light novels, Mahiro comes off mellower and nicer to Nyarko, mainly because they're just single-joke shorts rather than continuous stories. Comparing the TV series to Nyaruani makes him look more hot-headed, because he has to put up with more of Nyarko and Cuuko's antics.
- For a comparison, look at Remember my Love(craft-sensei) episode 11. Before (supposedly) going off to fight some powerful enemy, Nyarko hugs Mahiro tightly and asks if they can stay like that for just a minute, and if they can do this again when she returns; Mahiro's first reaction is surprise, but then he smiles softly and says "Sure." Now try to imagine the novel/TV Mahiro doing the same thing.
- Tsundere: A male Type B — he's a genuinely nice and friendly guy by default, but has little to no patience with Nyarko and co.'s madcap antics. These tendencies are more prominent with Nyarko; he claims to hate Nyarko's open affection, but no matter how often he brings out the fork, he obviously finds her cute. His deredere comes out when he, in Nyarko's body, realized how willing she is to protect him even with so lithe a body, deciding that he should start being nice to her.
- At the end of the first novel/episode 2 of the TV series, when Nyarko is saying goodbye and Mahiro says that he's going to miss her, she gushes "There's the dere!"
- Unfazed Everyman: After a while, even Nyarue's true form doesn't really trouble him. In episode 2 of the second series, Nyarko even remarks that his tolerance for this sort of thing is pretty impressive.
- Unwanted Harem
- Visible Silence
- We Want Our Jerk Back: In "How to Defeat a Kind Enemy", he makes Nyarko become a Magical Girl because he hopes it'll mellow her out; when this turns her outright Axe Crazy, he admits that she was better the way she was.
- Would Hit a Girl: With Nyarko around, it's either hit or get hit on. He usually chooses the former.
Nyarko's old friend/lover/enemy who also comes down to Earth and the humanized version of Cthugha, the Burning One.
A young boy with long blond hair, who happens to be the humanized version of Hastur, the Unspeakable One, godde... deity
of wind, depicted here more as the benign deity of shepherds than the Rapine Storm version
. He is also the son of the president of Carcosa Computer Entertainment (CCE), a famous video game developer.
- Actor Allusion: Tomokazu Seki plays a character with a Golden Super Mode — and he didn't even need Kyoji's help this time.
- Adorably Precocious Child: His overall appearance, although he also attends Mahiro's Boryo Municipal High School.
- Badass: Not as easily noticeable as Nyarko, Cuuko or even Mahiro, but he's still got good skills.
- Badass Adorable: See this incredibly cute little boy? He can also hold himself in battle.
- Bi the Way: In Volume 7, he admits that he feels warm and fuzzy around Luhy as much as he does with Mahiro, though he doesn't really understand anything further than that.
- Blow You Away
- Camp Gay
- Crossdressing Voices: And courtesy of none other than Rie Kugimiya, here using her cutesy tone reserved for her Shana Clones.
- The Cutie
- Dude Looks Like a Lady: He dresses as a guy, at least.
- Gay Option
- Hair Antennae: A couple of cowlicks.
- Hair of Gold, Heart of Gold
- Humanoid Abomination: His most common Mythos depiction looks like a masked man, clothed in yellow rags, often with tentacles slipping through its hem.
- Incompatible Orientation: He likes Mahiro a lot. As in the romantic variety.
- Innocent Blue Eyes
- In the Hood: Hastur, as the King, is often portrayed in artwork as being hooded. This is referenced visually by having Hasta wear a hoodie.
- Moe Anthropomorphism: Of Hastur, the Unspeakable.
- The Mole: Outright tells Mahiro that he was sent by his father to gather data on Earth's entertainment from his mother Yoriko on behalf of the CCE, but decides to stay instead after the mission is called off.
- Nice Guy: So sweet, cuddly and good-natured is he that it's hard to believe he is voiced by none other than Rie Kugimiya, queen of Shana Clones. This is probably the only reason he is the only member of Mahiro's harem who hasn't gotten the fork in season 1.
- No Sense of Direction
- Only Sane Man: Between Nyarko and Cuuko's squabbles, back in space grade school, he used to act as their middleman.
- Pinky Swear: Hasta suggests it to seal Mahiro's promise to consider his love confession again... in 25 million years.
- Rapunzel Hair: Tied in a long braid.
- Scenery Censor: Happens in the Beach Episode of season 2 when the water constantly flows to censor his chest.
- Spoiled Sweet
- Student Council President: During his, Nyarko and Cuuko's space elementary school days.
- Super Mode: His "King in Yellow Form", first seen in episode 3 of Nyarko-San W and voiced by Tomokazu Seki.
- Tender Tears: Following the tradition of Rie Kugimiya's characters, poor kid leaves the cafeteria crying in Episode 7, thinking Nyarko is pregnant with Mahiro's child.
- Token Mini-Moe: Of the main cast.
- Whole Costume Reference: The bandage-looking outfit he wears in "King in Yellow Form" is based on what TM Revolution wore in the music video and single cover for his song "Hot Limit".
Nyarko's pet, a female shantak (avian with horse's head and bat wings).
A green-haired woman and employee of Cthulhu Corporation, a rival video game developer to CCE (run by Hasta's father). She's also the humanized version of a Cthulhi, the star-spawn of Cthulhu himself
and the closest thing to the Big C to appear in the series to date.
- Absolute Cleavage: Her business suit is really low cut and revealing.
- Actor Allusion: In episode 9, she appears in a stage show as the Magical Girl Luhy Hiver; in episode 12, she wields an ice-based version of Hiver's Tek Lancer.
- An Ice Person: Uses ice attacks against some mooks during the final battle in Episode 12.
- Big Damn Heroes: Pulls this in episode 12 to help everyone fight off Roy Fogger the Lloiger.
- Cool Car: The Delorean. Yes, THE Delorean.
- Eldritch Abomination: Her true form is, naturally, a pulpy green humanoid monstrosity with a tentacled head and wings. Contrast that with this smoking-hot lady.
- Fallen-on-Hard-Times Job: From game console developer to takoyaki vendor and a Magical Girl actress... isn't it sad, Luhy?
- Heel-Face Turn: After Episode 6, she bounces back from her Villainous Breakdown and tells everyone she has no hard feelings, and she even helps Mahiro escape the cursed dating sim in Episode 8.
- Humiliation Conga: Yoriko warns her that Xoth-731 is too high-end and thus too expensive for commercial release, gets a call from her CEO telling her that she (and her entire department) had been laid off, and had to watch Cuuko reluctantly destroy Xoth-731 after it caused Deep Ones to be brainwashed by a Zombie Apocalypse game currently uploaded into the system... poor lady.
- Hot for Student: Becomes a teacher for Mahiro's class, and certainly acts this way towards Hasta.
- Hot Teacher: Becomes one late in the light novels.
- Ma'am Shock: When Mahiro ran by asking for help, Luhy seemed willing to help...until the cute little girl clinging to his back called her "obaa-chan". For that, she instantly ratted the pair out to Nyarko.
- And again in "How to Defeat a Kind Enemy", where Nyarko snarkily calls Luhy a 30-year-old, which causes her to ice up the room and angrily declare that even if you round her age, she's still in her 20s.
- Magical Girl: She performs as one in one of her jobs.
- Ms. Fanservice: Everything about her, from her glasses to her business suit, is attractive.
- Moe Anthropomorphism: Of none other than Cthulhu.
- Nothing Personal: When she runs into the cast after the Xoth incident, she's quick to insist that the only reason they were enemies is because of her old job with the Cthulhu Corporation and that she wants to bury the hatchet — especially with Hasta, since she thought he was an industrial spy and was therefore harsher towards him than everyone else.
- The Rival: She declares Mahiro one in the light novels after she realizes she has feelings for Hasta.
- Villainous Breakdown: Played for Laughs in Episode 6. Upon learning that Cthulhu Corp. is ditching its gaming department, she stoops in defeat with Dull Eyes of Unhappiness before she breaks down Laughing Mad in a desperate attempt to complete Xoth-731 before her superiors pull the plug on the project once and for all.
- Why Do You Keep Changing Jobs?: Largely because of her being laid off in Episode 6, she picks up different jobs later in the series.
- You Gotta Have Green Hair
Mahiro's mother and a part-time monster hunter.
- Absurdly Youthful Mother: Just look at her.
- Action Mom: Works as a part-time demon hunter (her introduction in Episode 4 even makes some Shout Outs to Monster Hunter).
- Actor Allusion: Several, including wearing a Kero-chan hairpin and quoting Sailor Mercury and Cure Moonlight.
- Admiring the Abomination: To an extent. While her son is somewhat freaked out and disturbed by Nyarko and Cuuko, she is more than happy to call some of their antics adorable, though she also makes it clear she will not hesitate to berate them should they cross her.
- Affectionate Nickname: Always calls Mahiro "Hiro-kun"; while pretending to be even fluffier during the Dating Sim episode, she went with "Mahiro-chan".
- Alliterative Name
- Ascended Fangirl: Just like her son, but unlike him she readily welcomes Nyarko, Cuuko and Hasta into their household.
- Badass: Like her son, she has yet to lose her sanity, even openly acknowledging the existence of several Cthulhu Mythos beings. Bonus points for actually scaring the crap out of Nyarko and Cuuko at the same time using a bunch of forks.
- Badass Adorable: In bright-and-sunny attitude and youthful appearance, Yoriko can easily be mistaken for for Mahiro's cute big sister.
- Cuddle Bug: Frequently embraces her son upon returning from her adventures, supposedly to recharge her "sononium".
- During the Trapped in TV Land episode, she pretends her personality's been "rewritten" as an excuse to be even snugglier towards Mahiro; when he says "Knock it off Mom, I know you're just faking it," she's quite disappointed.
- Gamer Chick: Collector of consoles of all sorts.
- Happily Married: At the start of the second series, she's in the middle of her 'seventeenth honeymoon. While this might seem like a cover for her monster-hunting, Yoriko confirms that her husband is fully aware of her work, and that his being so supportive is part of the reason she loves him so much (while blushing).
- Harem Nanny
- The Hunter: Her part time job. While she takes it seriously, Yoriko is not fanatical.
- Improbable Weapon User: Just like her son, she uses forks as her main weapon.
- It Runs on Nonsensoleum: She claims that she needs to cuddle Mahiro because it produces a substance called "Sononium" ("Musukonium" in Japanese) which she needs to function properly; if she doesn't get her daily dose she becomes depressed and lethargic.
- Mama Bear: Eased off on this after her initial meeting with Nyarko and Cuuko, especially after they explained themselves, but both are now conscientious enough to keep within Yoriko's good graces.
- More Dakka: Mahiro's fork = good. Yoriko's eight forks = better.
- Noodle Incident: In the light novels, it's revealed that Yoriko has apparently crossed paths with Atlach-Nacha (Atoko) in the past, and whatever happened between them resulted in Atoko utterly despising Yoriko.
- Older Than She Looks: Just looking at her, you'd never believe she had a 17-year-old son.
- Made more blatant in the second season, when she flashes back to the day her husband proposed; the only noticeable difference between then and now is the way she wears her hair.
- Overprotective Mom: Has minor elements of this, especially in her first appearance where she makes it very clear that she won't tolerate any untowards behavior directed at her Hiro-kun.
- Parental Incest: Not normally, but thanks to an alien love potion in episode 11 of Nyarko-San W, she starts leaning that way.
- Shipper on Deck: After warming up to Nyarko, Yoriko doesn't just give her approval for her and Mahiro to date, but seems to be gently nudging them towards each other. Particularly in episode 7 of the second TV series, where she convinces Mahiro to take Nyarko on a date to apologize for his Heroic BSOD-inducing Brutal Honesty, then makes sure Cuuko and Hasta don't interfere.
- Speaks Fluent Animal: She seems to be the only other character besides Nyarko that can understand what Shantak is saying.
A classmate of Mahiro, Nyarko, Cuuko and Hasta, who is always on the prowl for the hottest news in school.
- Beauty Mark: Look under the left side of her mouth. Yep, that's the one.
- Dark Horse Victory: She discusses this in the the Trapped in TV Land episode, pulling Mahiro into a secluded closet while Nyarko, Cuuko, and Hasta are busy fighting over him. However, she quickly lies and says that she was just joking, since as noted below she's fine with letting Nyarko have him.
- Genki Girl: Not as pronounced as Nyarko, but she definitely shows a lot of zeal with her hobby.
- Grand Theft Me: Throughout Episodes 9-10, courtesy of Isuka, a Yithian who wanted to alert Nyarko of her extremist kin's plans.
- Hair Decorations: Wears a ribbon shaped like a pair of megaphones.
- Hot Scoop
- I Want My Beloved to Be Happy: She has feelings for Mahiro, but because she feels she can't compete with Nyarko (and considers her a good friend), Tamao steps aside and becomes a Shipper on Deck.
- Iconic Item: Megaphones. They are even the principal design of her ribbons.
- Foreshadowing: Her body was temporarily taken over by Isuka, a Yithian. Yithians have a megaphone-shaped appendages.
- In-Series Nickname: "Walking Speaker"
- Matchmaker Crush: She works to get Mahiro and Nyarko together pretty much from Day 1, ignoring her own feelings for him.
- Tomboyish Ponytail
- Wistful Amnesia: Isuka thought she already erased Tamao's memories of her body being used by the Yithian. She actually remembers most details of their interaction, and decides to become her friend.
Mahiro's best friend and confidant.
- The Ace: Episode 4 of Nyarko-San W shows him bowling three perfect games in a row, and then doing the same with 9-Ball. This is implied in the same episode as being the result of Isurugi, the yithian, sending him "happiness waves" from the distant future in an attempt to make up for possessing his body.
- Bromantic Foil
- Gay Option: In the dating sim episode 8, it's suggested that he might confess his feelings for Mahiro if the latter fails to pick a love interest by the end of the game.
- Grand Theft Me: In Episodes 9-10, courtesy of Isurugi, a rogue Yithian attempting to pull a grander version of this trope upon the rest of humanity to acquire their entertainment. He willingly leaves Yoichi after pulling off a Heel-Face Turn.
- Nice Guy
- Only Sane Man: Besides Mahiro, he is the most level-headed of the cast... though on occasion he'd join their antics.
- Student Council President
- Welcome to Corneria: Gets stuck doing this in the Trapped in TV Land episode, which makes for a pretty funny image when Mahiro grabs his shoulders and shakes him, all with the text box hovering in mid-air between them.
A Yithian who possesses Tamao in Episodes 9-10
A rogue Yithian and member of an extremist faction of Yithians who intend to pull off a massive Grand Theft Me upon humanity

A beautiful woman in a kimono who comes to Mahiro's house in Remember my Love(craft-sensei)
, and plays a much larger (and more sinister) role in later novels. She's also the humanized form of Atlach-Nacha, the Spinner in Darkness.
- Aloof Dark-Haired Girl: Played with. She appears to be aloof, but is really a Covert Pervert.
- Canon Immigrant:
- In the original Mythos, Atlach-Nacha lacked any connotation of being squicky. Thanks to a certain game, this attribute was given to the Great Old One in Japan.
- Ato-ko herself first appears in Remember my Love(craft-sensei). The novels only briefly mentioned her as a certain being with a grudge against Yoriko, until her actual appearance in volume 10.
- Cluster Bleep Bomb: Her discussion with Cuuko is almost totally bleeped out. Whatever was said, it embarrasses even Cuuko.
- Covert Pervert: Once her gentle facade is taken off, she's quite the pervert of a level that mortifies even Cuuko.
- Cuckold: In the light novels, it's revealed that her "hobby" is stealing boyfriends away from her female friends, then dumping the guy afterwards since all she cared about was the schadenfreude she got out of destroying the relationship. The more in love said couple is, the more fun Ato-ko has breaking them up...and she's set her sights on Mahiro.
- Expy: Looks like Hirasaka Hatsune in a kimono.
- Foreshadowing: Her only "appearance" in the two regular series is in Nyarko-San W episode 11, where she sent Nyarko a box of chocolates...which turn out to be laced with a Love Potion, suggesting that she's attempting to set Mahiro and Nyarko up for her inevitable boyfriend-theft attempt.
- Humanoid Abomination: Basically a Giant Spider with a quasi-human face.
- The Internet Is for Porn: She asks Mahiro to help her find a picture of a dog she saw online earlier. When Mahiro opens up her browser history, it's nothing but porn (and judging by the timestamps, she was browsing a large number of sites at the same time). For that matter, her desktop image is a salacious image of herself.
- Moe Anthropomorphism: Of Atlach-Nacha.
- My Sensors Indicate You Want to Tap That: She can smell people's love for one another, which she uses to pick out the best moment to steal a guy from another woman. She also confirms that, despite Mahiro's fervent denial, he really does like Nyarko.
- Noodle Incident: In the light novels, it's revealed that Atoko utterly despises Yoriko because of some incident in the past where they crossed paths. Thus, her pursuit of Mahiro might have a minor revenge element to it as well.
- Weak, but Skilled: According to Nyarko, she's not amazingly powerful but is still a tough opponent because her attacks (webbing and poison) are hard to deal with.
- Yamato Nadeshiko: Looks the part, but not the attitude.
- Your Cheating Heart: When Ato-ko shows up in the light novels, it's revealed that she's a serial boyfriend-stealer. However, it has nothing to do with love whatsoever; she feeds on the despair that the break-up causes, and then immediately dumps the guy afterwards. Her current target is Mahiro, but she's still waiting for the best moment to strike.

An alien doujinshi
artist, who draws manga based on Mahiro after hearing about it from Nyarko. She visits and lives on Earth illegally in the hopes of meeting him someday.
- Affectionate Parody: Of the Yaoi Fangirl archetype, including gladly referring to herself as "rotten" (an insulting nickname for yaoi fans, at least in Japan) and saying her favorite quote is "There's no such thing as a girl who doesn't like homos!"
- All Women Are Lustful
- Butt Monkey: Her attempts to meet Mahiro are always thwarted in one way or another.
- Loony Fan: Of Mahiro's; every time she appears, she's plotting out the order in which she's going to shake his hand, get an interview, have him autograph her doujin, etc. It never once occurs to her that he might not enjoy being the "star" of a Boys Love comic...
- Moe Anthropomorphism: Of Ut'ulls-Hr'ehr, one of the Great Old Ones; one Japanese pronunciation of the name is "Uutsuru Heea" (ウーツル＝ヘーア), from which "Tsuruko" comes.
- Otaku Surrogate: She is obsessed with manga to the point of living on Earth and creating some herself.
- Ship Tease: With Yoichi, who runs into her at least twice. The first time time is a Not What It Looks Like moment in episode 4 of season 2 caused by Isurugi, the second in episode 11 with him being under the influence of a Love Potion.
- Yaoi Fan Girl: She is the artist for a yaoi doujinshi featuring Mahiro.
