The Katsuragi Family
Mari Katsuragi
Voiced by: Ryōka Yuzuki (JP), Shelley Calene-Black (EN)
Keima's mother, an ordinary Japanese housewife... who used to run with biker gangs. She runs a little cafe from the Katsuragi home, "Cafe Grandpa". She loves Keima, but worries about his future. She adores Elsie, whom she thinks is her husband's illegitimate daughter, and treats her like her own.
- Badass Biker: She was part of a motorcycle gang, and hasn't lost her touch, much to Keima's distress
◊. - Beware the Nice Ones: She's a really sweet mother. Just don't get on her bad side. Ever.
- Curtains Match the Window: She has orange hair and eyes.
- Death Glare: She sported an impressive one◊ when she called her husband after Elsea's introduction to the household.
- Drives Like Crazy: Those who get on a motorcycle with her as the driver will be left in a state of shock for a while.
- Expository Hairstyle Change: Whenever she gets angry, she lets her hair down.
- Fiery Redhead: Zig-Zagged. While she usually acts calm and gentle, the redheaded Mari used to be a member of a biker gang and still has a nasty temper that comes out when someone provokes her.
- Former Teen Rebel: Before she got married and had Keima, she was once part of a biker gang. Now she lives as an ordinary Japanese housewife who runs a café, but she can still get nasty if someone makes her angry.
- The Glasses Come Off: When she takes off her glasses, someone's about to enter a world of pain.
- Good Parents: She's a good and loving mother to both her son and Elsea who she believes is her husband's illegitimate daughter. There's this one scene in Kanon's conquest arc where she scolds Elsea for staying out late and then hugs her and says how worried she was about her. Then she scolds Keima for not looking after "his little sister".
- Hot-Blooded: Some things she really gets into.
- Letting Her Hair Down: When she undoes her Prim and Proper Bun, she stops acting like a docile housewife and goes full-on former Badass Biker mode.
- Like a Daughter to Me: Even though Elsie lied about being her husband's illegitimate child, Mari loves her as if she was her own daughter.
- Ms. Fanservice: The manga doesn't have much fanservice, but what little there is comes almost exclusively from her. Enough that her end card portrait◊ in season 1 episode 8 is done by Sano Toshihide, an Eroge artist.
- Obnoxious In-Laws: A mild case with her husband's father but she seems to get along with her mother-in-law. Her cafe, "Cafe Grandpa", is named in honor of Denma.
- Otaku: Although it doesn't come up much, Keima does mention that she's a bit of a manga fanatic. Which might be where he got his game obsession, come to think of it.
- Parental Substitute: Even though Elsie claims to be her husband's illegitimate daughter, Mari easily accepts her into her home and clearly loves her as much as she loves Keima. Elsie quickly accepts Mari as her mother figure. At the end of the manga, Elsie really becomes her daughter through a Cosmic Retcon.
- Pervert Revenge Mode: She leaves the man who dared to grope her ass in a pool of his own blood.
- Prim and Proper Bun: When she's in her pleasant mode, her hair is up in a bun.
- Red Baron: Used to be known as the "Snow Woman of the Mountain Pass".
- Retired Badass: She used to be a member of a biker gang before she settled down and became a housewife. But she's still willing to bring the smack-down, as one unlucky groper discovered.
- Tsundere: Sweet type. She can switch from gentle and nice mother to brash and hot-headed former biker, and right back at the drop of a hat when her husband and son make her angry.
- Why Couldn't You Be Different?: She has often wished Keima wasn't so game-obsessed and tried to enjoy the real world a little more. She does love him very much and doesn't really try to get in the way of his pastime, but she's still scared that one day he will end up as a crazy hobo married to a literal cardboard cutout if he continues down his current path of life.
- Woman Scorned: She is not happy when she thinks her husband is cheating on her, while Elsie (and later Haqua as a joke to her upon their first meeting) is actually just making it up.
- Wrench Wench: Shown to have been working on her motorcycle in the first season's 8th episode.
- Yamato Nadeshiko: Her baseline is a kind and loving Japanese housewife but don't forget that "Nadeshiko" is the name of a wild flower.
Keiichi Katsuragi
Keima's father, a man who is almost never home due to travel for work.
- Alliterative Name: His given name and surname begin with the same kanji.
- Disappeared Dad: He has to travel a lot for his work, so he isn't ever seen at home with his wife and son.
- The Ghost: The closest time when we first get to see him is in Keima's flashback but his face is blocked.
- Mistaken for Cheating: Elise (and Haqua as a joke) claim that Keiichi is their father. When Mari angrily calls him about having slept with other women, he's understandably confused about it.
- When You Coming Home, Dad?: He is often overseas for work.
Denma Katsuragi
Keima's grandfather and Keiichi's father. He once lived in Maijima City but gave his house to Keima's family when their house was destroyed in an earthquake 10 years prior to the story. He and his wife now live in Yamaguchi Village.
- Crappy Homemade Gift: He worked hard and made a bowl decorated with a game character for Keima. The picture looks very crappy, but it's the thought that counts.
- Doting Grandparent: He loves his grandson Keima and keeps the stuff that he sent to him.
- Obnoxious In-Laws: He isn't as welcoming to his daughter-in-law Mari as he is to his grandson Keima. It seems he has issues with Mari's delinquent background.
- Terrible Artist: His attempt at a picture of one of Keima's dating sim heroines is really bad.
Maijima Private Middle/High School Characters
Yuri Nikaido
Voiced by: Atsuko Tanaka (JP), Elizabeth Bunch (season 1), Maggie Flecknoe (season 2 and Goddesses) (EN)
Keima's homeroom teacher. She frequently abuses Keima, but (like the rest of his teachers) has mostly given up on scolding him.
- Action Girl: Her fight against Lune shows us what she's made of.
- Aloof Ally: She's captured two escaped level four spirits single-handedly, but since she's working on a different mission, hasn't revealed herself to Keima's group.
- Aloof Dark-Haired Girl: She's a tall, aloof and mysterious woman with black hair.
- Ambiguously Human: Her involvement in matters of Hell and ability to seal high-level demons call into question whether she's human. In the time travel arc, she's revealed to be the "other self" of Dokuro Skull. However, unlike demons, she seems to age like a human.
- Animal-Eared Headband: She wore a headband with cat ears in the outfit she wore for the teachers' skit.
- Anti-Hero: She's definitely one of the good guys, yet she's quite brutal against her opponents and doesn't hesitate to kill them.
- Badass Bystander: Gets called out to capture Level Four Weiss, but is working on a different mission from the rest of the Runaway Spirit Squad. For over ten years, with the help and inspiration of a time-traveled Keima, she sets out to enact the chain of events that lead to Keima foiling Vintage so that all the fighting can end.
- Badass Teacher: She's Keima's teacher and later chapters show she's quite the Action Girl.
- Brought Down to Badass: She is Dokurou, the super-powerful devil who helped Keima in the past, but in the present mentions that she's basically just human now. She still has access to some pretty powerful magic, though, just not the "curb-stomp everything the enemy sends at us" kind.
- But Now I Must Go: In the final chapter, having helped Keima save the human world and New Hell, she considers her job is done and decides to quit being a teacher.
- Chekhov's Gunman: Appears very early, but doesn't really do anything until Yui's arc.
- Clingy Jealous Girl: She kept on taking PFPs from Keima and beating him for playing dating sims in class because she was jealous that her "onii-chan" was paying attention to other girls, in games and later out of games too, and not to her.
- Collared by Fashion: Wears a studded collar. Given the nature of the collar, the studs are likely glued on.
- Dark Is Not Evil: She has dark hair and mostly sports dark-colored clothing, but is a stern yet decent teacher who also works from the sidelines in capturing Weiss.
- Dressed Like a Dominatrix: Her costume for the teacher's skit is a skimpy leotard that exposes her cleavage and abdomen. It also comes with thigh high boots and a whip.
- Good Is Not Nice: There's no doubt that she's Keima's ally, but she'll still beat the crap out of him.
- Hidden Agenda Hero: What her job is and what her intentions are remain unknown, though it's clear that she opposes Vintage and other similar groups.
- Hot Teacher: During Nagase's omakes, she disapproves of how Nikaido's style 'tempts' students before having a brief memory flash of kissing Keima.
- Jerk with a Heart of Gold: She acts stern and aloof, especially towards Keima. Despite that, she's actually a very nice person who cares about others.
- Mark of the Supernatural: She's the only (allegedly) human character with purple eyes, which is one of the first hints of her connection to Hell and demons.
- Mysterious Protector: Throughout the series, there's some moments where Nikaido appears to help in Keima's missions without letting him realize it, but it's unknown what her motives are until near the end of the series. In the past, she and Keima agreed to act like they don't know each other should they ever meet again, but she also promised to always be by Keima's side to protect him.
- Not So Stoic: Nikaido is normally quite cool and collected, even when dealing with rude or hostile people. However, the moment that Keima not coming back becomes a very real possibility, her composure is shot and she is reduced to crying out to Keimanote in the hopes that he is not forever lost to time, showing that despite everything, Dokurou/Nikaido never loved Keima any less than ten years ago.
- Secret Secret-Keeper: Turns out she knows a lot more about New Hell and Keima than she lets on, but makes an effort not to let him realize it.
- Stern Teacher: She isn't pleased with Keima playing galge games at class, but is willing to leave him be. However, if he talks rudely to her or gets too noisy, she won't hesitate to hit him and throw him out of the classroom.
- Sugar-and-Ice Personality: She's normally cool and collected, but she does show a softer side later in the series after she reveals her identity as Dokurou and her remaining love for her "onii-chan" Keima.
- When She Smiles: She finally smiles at Keima in the final chapter, when she says goodbye to him and thanks him for everything before they go their separate ways.
- Whip of Dominance: During the school's Mai-High Festival, Yuri Nikaidō gets Dressed Like a Dominatrix (it's supposed to be a demonic Cat Girl henchwoman) complete with a whip, which very much fits with her authoritative and domineering behavior. She herself is annoyed by it as this leads to some of the male students to openly ogle her, causing her to snap and use her whip on them and Keima notes that she seems like she's secretly enjoying it.
Miyako Terada

- Big "NO!": He bellows out an "Oh, No!" in the first episode of the Goddesses Arc, upon seeing Kanon cling onto Keima.
- Evil Is Petty: Well, he's not really evil per se, but.... During one of his test, he promised that he only approves extracurricular activities if the students get perfect grades on his test. Then, after the test, he happily approves everyone's activities despite their score because Keima, who he hates because he keeps playing games during lessons but always gets perfect scores, scores 99 out of 100.
- Gratuitous English: Despite being an English teacher and thus having an excuse to use the language, he doesn't appear to be that good at it.

- No Full Name Given: She's only ever referred to by her surname and her given name is unknown.
- Reasonable Authority Figure: When Shiori takes over the library, she goes out of her way to avoid telling the teachers despite it being the easiest solution since she doesn't want to get Shiori in trouble.

Other Buddies
Yukie Marui
Voiced by: Yuko Gibu (JP), Cara Duncan (EN)
Haqua's partner, a middle-aged Gokult saleslady. Not the fastest of workers, especially now she's getting on, but not to be underestimated either.
- Amazingly Embarrassing Parent: Yukie isn't Haqua actual mother, but their dynamic does make Haqua heavily resemble a Bratty Teenage Daughter who is terribly embarrassed of her mother. Haqua is especially annoyed by Yukie's habit of pushing Gokult merchandise on any likely takers.
- Boring Yet Practical: Her spirit-capturing method is to simply talk to the host every day. While slow, she's working on so many at once that Haqua's record is actually quite good.
- Bumbling Sidekick: In Haqua's eyes, Yukie is an utterly incompetent sidekick who wastes time trying to sell Gokult instead of actually working on their capture targets. Then it's subverted when Keima realizes Yukie is not useless; she works slowly, steadily and patiently on her targets. Haqua, being rather less patient and feeling the need to prove herself, initially dismisses her, until Keima makes her see that Yukie's method of capture does ultimately work.
- Fun T-Shirt: Wears one that says, "NO PUNK NO LIFE".
- Non-Standard Character Design: Yukie's design stands out for her dotted eyes and round face with afro-smooth hairstyle.
- Parental Substitute: She behaves as if Haqua was really her daughter, even though they're not actually related and Haqua is easily 200 years older than her.
- Shipper on Deck: Although not outright stated, she seems to try to manipulate Haqua and Keima getting together. Such as telling Keima that Haqua must be in a good mood because of him and how she supposedly talks about how good-looking he is. She also insists on him taking a bath and then tells Haqua that he already went home when she herself wants to take one. Keima is able to see through it though, unlike Haqua.
Ryou Asama
Voiced by: Takuma Terashima (JP), Blake Shepard (EN)
Ryou is Nora's partner, and apart from standing around being pretty doesn't seem to actually be good at anything. Due to his incompetence, Nora tends to end up doing most of the work, leading to unpredictable results.
- Big Damn Heroes: Surprisingly enough, he is the one to save Keima when Lune is looking for Fiore's signal and Keima is out with a cold.
- Brainless Beauty: He is handsome, but kinda stupid.
- Brainwashed and Crazy: An omake reveals that Fiore managed to brainwash him into joining Vintage's side and shouting Vintage slogans. Fortunately, Ryou's incompetence and inability to get her out of her jar aside, it was far too late for either of them to affect the outcome and after a good knock to the head Ryou returned to normal.
- Bumbling Sidekick: According to Nora, he's useless. He himself says that it ends quicker when he helps, though. Of course, the one time we see them working together he just gets in the way.
- Butt-Monkey: According to the author's notes, he's matched only by Elsie in being treated like a useless moron by smarter characters.
- Buxom Beauty Standard: He's only working for Hell because he likes Nora's boobs.
- Dumb Blonde: He's essentially brainless and can't even left or write or how to write his own name. He is, however, confident in his attractiveness and seems to enjoy flipping his blond hair.
- Handsome Lech: Ryou is very good-looking and claims to be a Casanova-type of man that can charm any girl. In reality, he's an idiot who turns girls off with his flamboyant and dumb behavior.
- Running Gag: Ryou is terrible at kanji and can't even write his own name. He always writes "Bald" on accident.
- Something about a Rose: The majority of his appearances has him holding a rose. The rose also holds his notes.
- Wasted Beauty: It's acknowledged in-universe that he is very pretty, but he's also so stupid that he's absolutely useless in his job of romancing girls to try and push the escape spirits out of their hearts.

- Creepy Doll: She often carries around a straw doll that looks like the Japanese version of a voodoo doll.
- Hellish Pupils: She inherited her grandmother's "fish eyes", but they look unsettling when coupled with her creepy behavior.
- I Just Want to Have Friends: Initially seems to be the case, with Airi noted to have no friends and coercing Keima into playing with her by threatening to break the bowl his grandfather made for him. But as it turns out, being alone doesn't trouble Airi in the least.
- Identical Granddaughter: She looks like her grandmother did when she was her age.
- No Full Name Given: Her grandmother's surname is Hinaga, but it's unknown if Airi has the same surname.
- The Noseless: She's drawn without a nose.
- Precocious Crush: She develops a crush on Keima after her grandmother's capture arc. She sends him a love letter that accidentally ends up with Dokurou in hell somehow before getting redirected back to him.

The matriarch of the Goido household.
