Fairy Clan

The Fairy Clan is one the five major races in Britannia. About three thousand years prior to the story, they formed an alliance together with the goddess, giant, and human races in a war against the Demon Clan for which they were victorious against. After the war, the fairies decided to live in peace and harmony within the Fairy King's Forest with a treaty insuring peace between them and the humans.

About 700 years prior to the story though, their king, Harlequin, mysteriously disappeared while searching for his wayward friends. Later, about 20 years prior to the story, further tragedy struck as their forest was destroyed a demon who mysteriously arrived and they were left homeless. However thanks to the efforts of Ban, the forest was revived and the Fairy Clan has lived there since.

Tropes pertaining to the Fairy Clan in general

The Ageless: Fairies do not physically age throughout their millennia years lifespan. Even after death, their bodies do not decompose and rot.
Born from Plants: Fairies are naturally born within nature, specifically from flowers and trees. Despite this, female fairies can somehow get visibly pregnant and give birth to human children, and male fairies can impregnate other species, as demonstrated by the human Ban impregnating Elaine and King conceiving with the giantess Diane. Though according to Elaine, this has never occurred in the history of fairies before.
Changeling Tale: Some fairies play pranks on humans by stealing their baby and swapping it with a fairy. Although, fairy royalty disapproves of this because it instigates hostility from humans.
Does This Remind You of Anything?: For the long-living and practically never-aging fairies, acquiring wings is seen as having become an adult. As such, there have been moments wherein characters discussing fairy wings in this context sound like they're referring to body parts other than wings. For example, the idea that bigger wings are seen as better.
The Fair Folk: Fairies are not bad in general, but they are cold in ways humans aren't. Elaine spent centuries killing thieves, King rendered the love of his life amnesiac, and the clan's common folk have a habit of not feeling empathy for their leaders.
Fairy Trickster: Not all fairies are the clear-cut friendly type. A number of them are somewhat Troll-ish in nature and there are those who aren't very nice.
Flight: A seemingly standard ability for most fairies.
Floral Theme Naming: The Fairy Kings before King/Harlequin, Gloxinia and Dahlia, are named after flowers.
Going Commando: According to a Q&A from the first Fanbook, the principle of underwear doesn't exist amongst the Fairy Clan. Basically, King, his sister, and every other fairy don't wear anything underneath.
Green Thumb: A number of the more powerful fairies are capable of magically manipulating plant life.
Growing Wings: Growing wings is a rite of passage that serves as proof they've become "adults". What's more, growing wings allows them to draw out even more magical power. Fairy wings, however, don't grow on their own- they have to be earned through personal character growth hence why they're seen as a proof of maturity. This is best shown when King and Elaine gain their wings. For King, he finally acquires his wings after passing Gloxinia's trial, in which he gained a huge amount of character growth via experiencing the first Fairy King's past and choosing a path Gloxinia did not. For Elaine, she finally acquires hers when she decides that she needs to help Ban out in battle instead of just letting him protect her. When it comes to size, fairy wings typically come out small when they first start growing in, according to Gloxinia. Elaine and her huge wings show that isn't always the case.
Hidden Elf Village: The Fairy King's Forest that the fairies live in which is magically isolated from most.
Ideal Illness Immunity: Fairies never suffer from illness.
Land of Faerie: The Fairy King's Forest which is the home of the Fairy Clan and other creatures closely associated with them.
Long-Lived: Fairies have extremely long lifespans. According to a Q&A in the first Fanbook, the average lifespan of a fairy is 1000-1500 years. A Q&A from Chapter 132 further adds that the lifespan of the Fairy King variety in particular is the longest out of all the different species.
Nature Spirit: The Sacred Tree at the center of the Fairy King's Forest, which was created by the same entity that created the Supreme Deity and the Demon King. It's unknown just how sentient it is, but it is the one that selects the Fairy Kings and gives them their signature weapons.
No Biological Sex: It isn't rare for fairies to be born with no determinate sex. They later become male or female depending on the gender of the person they fall in love with. This also applies to half-fairy hybrids.
Our Fairies Are Different:
- King and his sister, Elaine, are long living child-like fairies capable of levitating themselves and other things. For some reason though, only they appear to be wingless initially. Other fairies on the other hand, have wings. These wings in particular are believed by some humans to be capable of being made into medicine which can extend human life. As such some humans would go to some really heinous lengths to acquire these wings.
- Fairies are also noteworthy as their corpses don't rot even after several centuries.
- An extra page in Volume 22 of the manga reveals the nature of fairy wings and why King and Elaine appear to not have them initially. Fairy wings are things that fairies need to be grow first and are seen as proof that such fairies are adults by their peers. Fairies actually can fly very well prior to having wings however possessing wings enables them to draw out even more power. Over the course of the story, it's further revealed that fairies only acquire wings through personal Character Development hence explaining why they are seen as proof of maturity. As such becoming an adult for a fairy is something that comes from personal growth rather than something that comes naturally over the course of time.
- In a Q&A from Nakaba's editor for the series, it's revealed that fairies are actually born from plants and therefore have no parents. Also, fairies like King and Elaine are siblings because they were born from the same plant.
- In the same Q&A as the one above, it's explained that creatures like Black Hounds and Hide and Seeks are called fairies but only in a broad sense. They should thus be thought of as different species.
Pointy Ears: Most fairies commonly have long elvish ears. King and Elaine are rare exceptions.
Power Gives You Wings: Inverted. Having wings allow fairies to draw out more power as explained in an extra page in Volume 22 of the manga. Acquiring wings however requires personal character growth hence why in fairy culture, wings are seen as proof of maturity and fairies with wings are seen as "adults".
Really 700 Years Old: Fairies are a long lived race and thus a number of them have extremely youthful appearances despite being several centuries old. The first Fanbook reveals the ages for three youthful looking ones. Both King and Helbram are 1300 years old while Elaine's 1000 years old. While child-like fairies are apparently quite common, there are however some who appear to be significantly older as they sport beards and such.
Signature Scent: Individual fairies tend to have distinctive scents.
- King in his normal fairy form, has a distinctive flowery scent which according to a Q&A in the first Fanbook is that of sweet olive (Osmanthus fragrans). It however changes to that of a musty, sweaty smell in his human form according to Gowther and the other Sins.
- According to another Q&A in the first Fanbook also, Elaine smells like lavender.
- A Q&A in Chapter 152 gives the scents for three other fairies. Helbram smells like roses, Gerheade smells like mint, and Gloxinia the First Fairy King smells like ginger.
Squishy Wizard: As revealed by the Power Level stats of certain fairies listed in the second Fanbook, fairies tend to be great in magic but poor in physical strength. The really powerful fairies listed in the Fanbook in particular have ridiculously high magic stats but are also both listed having a physical stat of 0.
We Have Become Complacent: Due to constantly relying on their Fairy King for various challenges and threats, the Fairy Clan had become slothful. Rather than solve the problems themselves, they constantly passed the responsibility to whoever was their king. As a result, they became too comfortable in their carefree lives. It however takes King's resolve to protect them despite being thrown out by them that their former pride returned.
Winged Humanoid:
- Most fairies have the typical insect wings which fairies are commonly depicted with. Some humans believe that a medicine that can extend life can be made from these wings. As a result, fairies have been tricked and captured by less than savory humans in order to pluck their wings. Though wings are a common attribute of the Fairy Clan, King and Elaine initially do not have them for some reason. Them not having wings has actually been questioned on by a number of characters especially since all the previous Fairy Kings before King had very prominent wings.
- An extra page in Volume 22 of the manga reveals that wings are seen as a proof of maturity among fairies and that they allow fairies to draw out even more power. Acquiring wings however as revealed further in the story is something that requires a fairy going through personal character growth hence explaining why wings are seen as proof of maturity.

Magic: Miracle Wind

^{Click here to see her after growing wings}

Elaine is King's sister, and the Guardian Saint of the Fountain of Youth, who was killed by a demon from the Demon Clan in the original Fairy King's Forest. Since her death, her spirit resides in the Capital of the Dead while her corpse resides in the revived Fairy King's Forest.

Adaptational Modesty: The manga shows her corpse completely in the nude. The anime let it have her white dress on.
Adaptation Expansion:
- The two episode anime OVA The Seven Deadly Sins: Ban's Side Story primarily covers Elaine and Ban's backstory but adds a few extra scenes such as a moment wherein Elaine immediately gets drunk after just one sip from some ale that Ban brought for her.
- The Light Novel spinoff The Seven Deadly Sins: Seven Days by Mamoru Iwasa and the manga adaption of said Light Novel spinoff The Seven Deadly Sins: Seven Days - The Thief and The Holy Girl also expand on Elaine and Ban's backstory. Specifically, the spinoff and its manga adaptation fleshes out more in full detail the seven days that Elaine and Ban spent together, explicitly covering each and every single day before the inevitable tragedy. They also expand on other things such as covering Helbram's capture more in detail, and explaining why Elaine was all alone with no other fairy around during her time with Ban.
Babies Ever After: After the end of the series, Elaine gives birth to Ban's son, Lancelot.
Back from the Dead: At first she Came Back Wrong, but thanks to both Ban and Jericho, she comes to her senses and for a time, traveled alongside them. As Merascylla, the one who resurrected Elaine, had seemingly died then, everyone figured that rather than Merascylla's power or Elaine's regrets, it was instead her strong feelings for Ban that kept her around in the mortal realm. This assumption however proved to be wrong as it was later discovered that Merasyclla had survived. Ban then in an act to save Meliodas decides he needs to off Merascylla, something that would naturally lead to Elaine being once again parted from Ban. Despite this however, Elaine tells Ban prior she understands and bares no grudge against this course of action. Much later, it's revealed that Ban's attack on Merascylla didn't completely kill her but Elaine is rendered bedridden for the most part and requires being healed by Elizabeth to be kept alive. Ban finally gives most of his lifeforce to Elaine so he can perfectly resurrect her, at the cost of his immortality.
Blow You Away: She specializes in Wind Magic which the second Fanbook reveals its name to be Miracle Wind.
Came Back Wrong: She's resurrected by Merascylla as an undead being that's completely obsessed with Ban. Her personality is easily brought back to normal, but her health slowly deteriorates as she's kept in the living world by Merascylla's power.
Can't Hold Her Liquor:
- In the OVA about Ban's backstory, when Ban brings some ale for Elaine to try, she immediately gets drunk after just one sip.
- Averted in the manga adaption of the Seven Days Light Novel spinoff. In a moment almost similar to the one in the OVA, Ban brings Elaine back some fermented fruit he received as a reward for helping some walking mushrooms. While she finds the natural wine bitter, she doesn't get immediately drunk from tasting it.
Clingy Jealous Girl: After being resurrected by Merascylla, Elaine can't stand anyone getting close to her Ban and she will attack anyone just for spending time with him. She especially hates Jericho because she is also in love with Ban and has been traveling with him, which she always wanted to do. Elaine fortunately however is brought to her senses.
Common Law Marriage: After she's perfectly resurrected, Elaine can spend her new life together with Ban. However, neither of them is interested in having a formal wedding ceremony, even though they eventually become king and queen of their own kingdom and have a son together.
Curtains Match the Window: Her hair and eyes are both yellow.
Cute Ghost Girl: She shows herself as a ghost at the Capital of the Dead, appearing as the cute fairy girl she was when alive.
Damaged Soul: Because of Merascylla, Elaine comes back to life. Ban is happy that he has his lover back, but the problem is that now she's a dangerous Yandere that will try to kill anyone who has gotten close to him. Thanks to Jericho however, she gets better.
Devoted to You: Years after her death, Ban is still deeply in love with her and is looking for a way to bring her back. He even dreams about her all the time.
Died in Your Arms Tonight: She died in Ban's arms.
Ethereal White Dress: As a ghost, she appears wearing the white dress that she wore when alive.
Evil Costume Switch: She dons a black dress made out of petals when she's resurrected by Merascylla.
Friendly Ghost: She's the ghost of a kind-hearted fairy who is in a Star-Crossed Lovers type of relationship with the immortal living bad boy Ban.
Full-Frontal Assault: After her revival, Elaine attacks the other fairies that got close to Ban while completely naked.
Gold and White Are Divine: She shows up as a Cute Ghost Girl with a noticeably angelic appearance, given her long flowing white dress, white wings, and golden hair and eyes.
Good Costume Switch: After returning to normal, she starts to wear a maid outfit.
Hair of Gold, Heart of Gold: She is a golden-haired fairy with an overall kind nature.
Heroic Sacrifice: Elaine originally sacrificed her life to give Ban his immortality so he could live.
Huge Guy, Tiny Girl: With Ban. She barely reaches his chest.
I Got Bigger: Growing her wings makes Elaine into an adult according to fairy biology. As a bonus, her physical appearance changes from a child to a petite young woman.
Interspecies Romance: Elaine is a fairy who is in love with Ban, a human.
The Lost Lenore: Ban still loves Elaine even decades after her death and his main goal is bringing her back to life.
Luminescent Blush: She had this moment when Ban was skinny dipping and wanted her to join him, and when she found out that Ban overheard that she wanted him to take her.
MacGuffin Guardian: She was charged with protecting the Fountain of Youth while King was away.
Mayfly–December Romance: As a fairy, Elaine had a much longer lifespan than her human lover Ban and had lived for centuries before they met. Ironically, the situation got reversed when Ban became immortal while Elaine died. Ban ultimately gives up his immortality to perfectly resurrect Elaine and they'll stay together as long as he lives.
Mouth To Mouth Force Feeding: To save Ban from his fatal injuries, she gave him water from the Fountain of Youth through her mouth via a kiss.
Naked on Revival: When Elaine was killed, the fairies preserved her body in the new Fairy King's Forest naked. When she comes back to life because of Merascylla's magic, she performs a Full-Frontal Assault against other fairies until she uses her magic to make a Garden Garment for herself. Averted in the anime, where she was preserved with her clothes on, but she still replaces her clothes with an Evil Costume Switch shortly after being revived.
Navel-Deep Neckline: Her Evil Costume Switch has a plunging neckline, although Elaine doesn't have much cleavage to show.
Nice Girl: A very kind-hearted fairy when you aren't trying to doom her people. In fact, her kindness is one of the factors in why Ban softens up.
Opposites Attract: Ban's a rather tall originally normal-aged Jerk with a Heart of Gold human thief. Elaine's a Really 700 Years Old Token Mini-Moe saintly Fairy guardian. They genuinely fell for each other even when circumstances made them even more opposite in nature, what with Ban becoming an undying immortal and Elaine becoming a ghost.
Pacifist Wind: She specializes in wind magic named "Miracle Wind", is the Guardian Saint of the Fountain of Youth, is a non-combatant, and apart from her disdain towards humans for always trying to take from the fountain of youth (that she eventually grows out of), she has a kind, gentle demeanor and angelic appearance.
Posthumous Character: She is long dead prior to the beginning of the series, though she gets resurrected later on.
Power Level: According to the second Fanbook, her level is 2830 with her individual stats being Magic: 2010, Strength: 20, and Spirit: 800. After gaining her wings, her level skyrockets to 21,050 with her individual stats being Magic: 18000, Strength: 50, and Spirit: 3000.
Power Makes Your Hair Grow: Growing her wings causes her hair to grow past her shoulders.
The Power of Love: She became fiercely determined to save Ban's life from Merascylla's serpentine form, and when that happened, her body started to glow, dramatically matured, and she bolted straight at Merascylla's maw at blinding speed, pulling Ban out before she Merascylla even had time to react.
Restored My Faith in Humanity: During her time protecting the fountain, Elaine developed hatred towards humans due to all approaching her trying to steal the fountain and destroy the forest. Her thoughts change when she meets Ban and the forest actively protects him.
Resurrection Sickness: After she's resurrected by Merascylla, Elaine is gradually rendered bedridden for the most part and requires Elizabeth's healing magic to be kept alive. She's healed once Ban sacrifices his immortality to expand her lifespan.
Revenant Zombie: She's essentially turned into this by Merascylla who brought Elaine back to life as one of the demon's minions using her regrets and longing for Ban as the catalyst. Initially driven by negative emotions, Elaine fortunately regains her senses and remains in the mortal plane driven instead by her strong feelings of love for Ban.
Samaritan Relationship Starter: When Ban came to steal the Fountain of Youth from the Fairy King's Forest, he gave up on it after Elaine told him that if he were to take the Fountain of Youth, the forest surrounding it would die. Elaine, who was used to the previous human thieves being all selfish and greedy, became interested in Ban for being the first human who showed her some form of selflessness and kindness.
Shameless Fanservice Girl: Although Elaine understands the concept of nudity, she like the rest of the Fairy Clan don't really get the concept of wearing any underwear underneath and are rather indifferent about it. This actually serves as the focus of a side story after Chapter 219. Having been told beforehand by Jericho to "at least put on some underwear if she wants to be call herself a proper lady", she asks Ban to help find her some panties to which he agrees to. Being completely innocent on the matter due to it being foreign to her, she's not at all bothered at revealing to others that she and Ban are shopping for panties and actually finds the excursion fun. She even goes playing around upon arriving at the panty store, making underwear fly around. She however comes to find wearing panties to be rather uncomfortable. In the end, rather than pick a panty for herself, Elaine chooses underwear for Ban instead, one which gets highlighted in a pic with Ban wearing nothing but it like an underwear model. He does still buy a panty for Elaine as well though as a cute little secret present for her.
Shipper on Deck:
- For Meliodas and Elizabeth as she playfully teases the latter about thinking of the former.
- In the same scene from above, she also ships her brother and Diane as she (like what she with the above couple) playfully teases the latter about thinking of King.
Single Woman Seeks Good Man: She didn't fall in love with Ban because he is an amoral and greedy rogue, but because she could see the good heart he has underneath his rough exterior. He was the first decent human she ever met and also, the first person to befriend her after she spent 700 years alone protecting the Fountain of Youth.
Star-Crossed Lovers: With Ban. She's dead and Ban's immortal however Ban is trying to find a way to rectify this. They get reunited when Elaine gets resurrected and she's brought back to her senses.
Telepathy: She can read minds, thoughts, and memories.
Token Mini-Moe: She's a 1000 year old fairy with an appearance that can be mistaken for a prepubescent human girl.
Uptown Girl: She's the Fairy King's sister and her lover Ban is an ex-knight turned criminal, who was even a thief when they first met.
Vine Tentacles: Inside the Fairy King's Forest, she can control the branches of trees as her limbs, thus being capable of immobilizing or harming individuals.
Violently Protective Girlfriend: Ban might be immortal, but it won't stop her from defending him if need be. Upon Elaine being resurrected, she promptly paid Gerheade back for hurting Ban.
Yandere: Upon being resurrected by Merascylla's demonic powers, she became completely obsessed with Ban, to a point that she's unwilling to share him with anyone else. She even lashes out against those who had just simply spent time with him such as the other fairies. Fixed thanks to a "Reason You Suck" Speech from Jericho and Ban accepting her good and bad.

Ende

Voiced by: Shougo Yano (Japanese)^{Foreign VAs}

A fairy who doesn't harbor as much resentment for Harlequin upon his return like most of the rest.

Anime Hair: She has a rather unique hairstyle which basically looks like a candle flame or a flower bud. In the middle and directly above her forehead, she has a patch of hair that's a different color than the rest.
Establishing Character Moment: When she's first encountered, Ende's the only fairy who isn't hurling outright insults at King.
Token Good Teammate: Amidst the most of the fairies who resent King for leaving the forest, Ende's the only one who interacts with him in a non-antagonistic way. Rather than anger, she expresses sadness over the tragedy that befell their home. She's also not antagonistic to Ban either despite him being a human.

Puora

Voiced by: Shougo Yano (Japanese), Abby Trott (English)^{Foreign VAs}

A distinctive looking small fairy who's one of the more frequently seen fairies.

Eyes Always Shut: His eyes are three lines, giving the impression that they're closed.
The Gadfly: Pulls a number of pranks on Jericho when she comes to the forest.
The Imp: A rather mischievous though not malevolent little fairy who pulls a number of pranks on Jericho for fun.

Gerheade

Voiced by: Sumire Morohoshi (Japanese), Laura Stahl (English)^{Foreign VAs}

Magic: Guardian

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

Gerheade is one of the Fairy King's Forest's oldest inhabitants and the adviser of the Fairy King. She however doesn't share the same sentiments that most of her fellow fairies of the restored Fairy King's forest have as she doesn't accept Ban, a mere human, as the new Fairy King. Instead, she sees Harlequin the disgraced former Fairy King as being more worthy of the title.

Anti-Villain: Only wants what's best for the Fairy King's Forest however, the means she attempts to achieve this places her as a villain.
An Arm and a Leg: She had both of her legs cut off by a human 3,000 years ago.
Evil Chancellor: Somewhat in a way. Due to her racism towards humans, she sees Ban as being unworthy of the title of Fairy King. Thus she tries to restore Harlequin's position by attacking Ban. Ban is actually more than willing to comply with her demands and leave as he didn't really want the job in the first place however she has other plans as his blood is what sustains the Fairy King's Forest.
Eye-Obscuring Hat: Wears a beenie of sorts that covers her right eye and ear. The back of the second Fanbook which reveals the colors of a number of characters shows that her hat is actually basically the lower part of an upside down rose-like flower. It's later revealed that her hat isn't covering her right eye and ear. It's actually hiding the fact that a part of the right side of her head had been sliced off.
Fantastic Racism: Doesn't hold humans in very high regards.
Hiding the Handicap: It's later revealed that her clothes hide the fact that she's missing legs and a part of the right side of her head. These along with her damaged wings are wounds she received 3,000 years ago during the moment when a group of humans she and other members of Stigma thought were allies saw an opportunity to finally get revenge for Stigma slaughtering their village in the past just because they helped an injured demon.
Irony: Despite wanting what's best for the forest, she doesn't seem to realize that the forest itself was fond of Ban from the start, even when he tried to steal the elixir as it could sense the pure heart within him. In contrast, Gerheade is taking the exact opposite route and acting more like a selfish human she claims Ban to be.
Magic Wand: She wields a berry plant as one to do plant based magic.
Morality Chain: Her (presumed) death is what led to her older brother Gloxinia's Face–Heel Turn and joining the demons.
Obviously Evil: Played With. She's dressed in a more shady looking attire than regular fairies and did attack Ban. However, she only did so for the sake of the forest. Then again there's also the fact that Gloxinia as one of the Ten Commandments used her likeness for the flower doll that fought in his stead, something that casts a bit of suspicion towards her.
The Older Immortal: The second Fanbook reveals that Gerheade is 4,200 years old. Without including certain characters who were initially sealed as their aging stopped whilst in that state, this age makes Gerheade apparently the oldest living character so far revealed in the series.
Pimped-Out Dress: She wears a more elegant gown than most other fairies. The back of the second Fanbook which reveals the colors of a number of characters shows that her gown is actually basically an upside down rose-like flower with its petals serving as the gown's frills.
Pointy Ears: She has long and pointy elf-like ears.
Power Level: According to the second Fanbook, her level is 2370 with her individual stats being Magic: 1890, Strength: 10, and Spirit: 470.
Replacement Goldfish: Rou had a soft spot for Gerheade because she reminded him of his deceased childhood friend. This is why he spared her life despite hating the non-human clans.
Took a Level in Cynic: It's discovered during the test given to King and Diane by Gloxinia and Dolor that Gerheade actually had a much different personality 3,000 years ago during the holy war. She had a brighter personality which along with her being Gloxinia's little sister, reminded King of Elaine. Certain events however happened which changed Gerheade from this to who she became in the present.
Undying Loyalty: Among the fairies, she's practically the only one who's still fervently loyal to Harlequin when he returns to his people despite the majority of the other fairies' opinion of him. Her loyalty to Harlequin however only extends to him and not to his successor.
Well-Intentioned Extremist: She wants what's best for the forest and willing to kill Ban for it (which he actually didn't mind). But crossed a line when she purposefully got Elaine's body involved in her attempt. This, Ban would not stand for and, low opinion of humans or not, gave Gerharde a fair warning what he would do if she did something like that again.

Invisible

A small fairy with the ability to turn invisible. She is a close friend of Deathpierce and only allows him to see her.

Adaptational Modesty: In the manga, she's an Invisible Streaker. In the anime, she is fully clothed, with a white dress and white stockings.
Fairy Companion: She is Deathpierce's tiny fairy friend who only he can see.
Invisibility: Her power allows her presence to be completely masked. She can't be seen or even be sensed at all. Due to Deathpierce being friends with her since he was a child, only he can see her.
Personality Powers: Invisible is extremely bashful. Her ability, in reflection to her personality, is masking her presence completely from everyone except for her friend Deathpierce.
Satellite Character: Besides her being Deathpierce's Fairy Companion, nothing is known about her and has no purpose to be in the story other than being close to Deathpierce.
Steven Ulysses Perhero: Her name is Invisible and she is normally invisible.
What Happened to the Mouse?: She does not appear in Grudge of Edinburgh, likely having left Deathpierce after became a full-blown Fantastic Racist.

The Fair Folk: He is based on the Puck from English folklore and follows the more traditional, mischievous depiction of a fairy.

^{Click here to see his smaller form}

Oslow is King's pet black hound. He was initially encountered by Meliodas and the Sins with him on their way to the Capital of the Dead. After the incident there, he was kept away by King due to the fact that his favorite food is pork. He later reappears when King summons him in order to get to Liones.

Adaptational Late Appearance: In the first season of the anime adaptation, his scenes during the Capital of the Dead arc are removed. However, he still appears later on to provide his important role when he teleports Diane to Liones, though the context of his appearance in such is greatly changed.
Amazing Technicolor Wildlife: As shown on the side of Volume 9 of the manga, he's a light blue dog whose markings and fur around his neck are yellow.
Canis Major: He's a hound that can grow into the size of a building. He can even get to a size relative to the giantess Diane.
Chekhov's Gunman: He's initially introduced alongside King in their first appearance, however he seemingly disappears from the story afterwards. Later on, he reappears with an explanation for his long absence.
Dark Is Not Evil: He's just King's loyal pet dog despite looking like a Hellhound.
Eyes Always Shut: His smallest form always has his eyes shut.
Hellhound: Subverted. While he looks the part and was even somewhat antagonistic when he first appeared, he is actually on the Sins' side. He may actually be a Cù Sìth.
Our Fairies Are Different: Oslow is apparently one of the fairy species who live between the Human and Fairy Realms.
Precious Puppy: His smallest form is the size of a puppy.
Reincarnated as a Non-Humanoid: Oslow is the reincarnation of Rou, the human who promised that he would protect Gerheade no matter what form he took in his next life. In a twist of fate, he reincarnated as a black hound who is devoted to protecting Gerheade and the Fairy King.
Sizeshifter: Oslow is capable of changing his size.
Super-Speed: He is capable of running at incredible super speeds.
Swallowed Whole: How he teleports people to other places. This posed a problem when he tried to teleport Diane, whose butt got caught in his mouth.
Teleportation: He is actually a creature capable of teleporting people to other places via eating them. He is also capable of teleporting himself via portals.
Trademark Favorite Food: His favorite food is pork, which is why he was kept away from Hawk (and, as a result, most of the Sins) for a long time.
Undying Loyalty: He is always there for King whenever he needs moral or emotional support. Even when the whole Fairy Kingdom turned on the two of them, he stayed by King's side, protecting him from further damage. This was apparently an extension of his loyalty to Gerheade, who wanted him to protect the Fairy King in her place.
