This kind of romance can be portrayed any number of ways in media. If it is normal for one half of a couple to just have magic and the other to not, it signals to viewers that the setting is Mundane Fantastic. If society loathes this kind of romance, it can lead to Star-Crossed Lovers while signalling to viewers that there is Fantastic Racism in the setting.
The couple may also have to deal with issues that may arise where one half of the couple is just that much more powerful. If the Muggle is rather tolerant and understanding though, and both the Muggle and the magic user work at it if necessary, the issue can be smoothed over. If the power balance issue cannot be resolved adequately, it can lead to an end in the relationship.
Factors that affect how the society views this sort of romance depend on the nature of magical society, mundane society, any sort of Masquerade, how magic is acquired (learned vs. inherent gift), other intrinsic differences between muggles and mages, etc.
If a relationship of this sort exists within the setting, odds are that there may be an aesop about tolerance.
See also Interspecies Romance, where there is a lot of overlap in terms of themes and portrayals.
- Haku from Naruto is the result of one of these. Due to the infamous wars of the "Bloody Mist," people with "Kekkai Genkai" (Bloodline limits, as in people with inherited abilities as supposed to just secret technqiues) were feared. Haku inherited his kekkai genkai of Hyotan (Ice release, combining water and wind chakra to make ice) from his mother. Despite her best efforts, the father, one of the people discriminating against those with Kekkai Genkai, found out and he ended up snapping, killing his wife and would've killed Haku if not him activating his powers to protect himself.
- Shuro, a muggle, from Delicious in Dungeon is in love with Falin, a cleric. It's unknown yet whether she returned his feelings or not.
- Louise and Saito from The Familiar of Zero, a summoner and a normal person respectively, have this sort of relationship, and eventually get married.
- Raki, an ordinary human, and Claire, a warrior with Yoma-related powers, are heavily implied to have become an Official Couple at the end of Claymore.
- In Karin, Karin, a vampire, and Kenta, an ordinary human, develop a relationship over the course of the manga. Then becomes subverted (kinda); Karin is actually the embodiment of a vampiric fertility figure known as the Psyche, which was passed down one of her family lines before marrying into the current one. This allows her to go into the light no problem and over time, becomes more like a human than a vampire, while also making her vulnerable to vampires who want to rejuvenate their fertility. The manga's ending has her family erase their memories of them from her so she could live a normal and safe life with Kenta. Kenta is the only one who knows this outside the family and is understandably quite heartbroken over the ordeal.
- Kiki's Delivery Service has Kiki's parents (her mom is a witch and her dad isn't). Kiki and Tombo have some romantic tension, although it doesn't resolve into anything definite. Witch/muggle relationships are kind of inevitable since witches are a One-Gender Race.
- There are several examples of this in Lyrical Nanoha including Chrono/Amy and Quint/Genya. It's presumably a common occurrence on Midchilda.
- It's stated in chapter 65 of Miss Kobayashi's Dragon Maid that Shouta's mother has no magical knowledge whatsover (in contrast to his father). This was the main reason why she couldn't accompany him to his mage exam, since she wouldn't be able to get past the CAPTCHA.
- Sabrina the Teenage Witch:
- Sabrina is the result of a relationship between a wizard and a muggle woman. She's an oddity amongst witches as a result.
- Sabrina has had human love interests, most prominently Harvey.
- The titular character of Superman has the Intrepid Reporter Lois Lane, who is otherwise ordinary, as a Love Interest.
- Peter Parker, the Spider-Man, also has the ordinary Mary Jane Watson as a Love Interest.
- True to its Harry Potter roots, Child of the Storm has this fairly frequently.
- Quite common in Pokémon Reset Bloodlines. Partly this is due to bloodliners being more predominantly female, which gives them rather limited options in the romance department. One of them is taking a chance with a non-bloodliner boy and hope that he doesn't fall into Fantastic Racism.
- The Stand Still, Stay Silent fandom's favorite non-canon pairing happens to be made out of a Flat-Earth Atheist and a mage who isn't the type to use his powers just for the sake of proving him wrong, making this trope show up in quite a few stories. The existence of magic is far from being hidden in the setting, but there are a couple entire nations outright refusing to believe it exists while it's taken for granted in the three others.
- In the Harry Potter spinoff Fantastic Beasts and Where to Find Them, such relationships are outright banned in America, due to small but dangerous anti-magical faction. That doesn't stop a blooming romance between Jacob Kowalski, an ordinary Muggle baker, and Queenie Goldstein, a witch. They end up becoming Star-Crossed Lovers due to magical society's laws requiring Jacob's memories be erased.
- The Star Wars prequels depict the romance between Jedi Knight Anakin Skywalker and Padmé Amidala, whose lack of Force powers makes her the equivalent of a Muggle. It ends in tragedy.
- Many examples in Discworld:
- Carrot, an ordinary human, has a Will They or Won't They? version of this with Angua, a werewolf. Sally, a vampire, also showed interest before backing off due to not wanting to get into a fight with Angua.
- Not uncommon among witches: Magrat Garlick marries the muggle King of Lancre, while Nanny Ogg has outlived three husbands, dated vastly more, and raised a sprawling extended family.
- Wizards are contractually required to avoid this, since they have a small chance of fathering the living embodiment of With Great Power Comes Great Insanity. There's mention of retired wizards pursuing romance, albeit quite carefully.
- In Harry Potter, it is reasonably common for Wizards and Witches to marry Muggles. The resulting children tend to be called Half-Bloods. The Big Bad is the result of one particularly disastrous example that involved a Love Potion.
- Harry Dresden of The Dresden Files stories was born of this sort of relationship, with his mother, a very powerful witch with a number of dark associations falling in love with a poor travelling magician, before dying in childbirth and not naturally, either. It's repeatedly noted that her husband wasn't powerful in any way, but that he was a good man. Dresden himself follows his mother with a (ultimately tragic) relationship with tabloid reporter Susan Rodriguez, and has had a star-crossed will-they-or-wont-they with Karrin Murphy for some time.
- In Bras and Broomsticks, Rachel, a witch, has a human boyfriend named Raf. He turns out to be an Understanding Boyfriend after being told about it.
- In The Two Princesses of Bamarre, Princess Addie develops a crush on her father's new court sorceror, Rhys. Rhys is friendly and helpful to her (especially after she makes the decision to set out on a quest for the cure) and does things that make her wonder whether the attraction might be reciprocated. It is, and they marry at the end of the book. In this case, it doubles as Interspecies Romance, because sorcerors are a different sort of being from humans.
- In The Belgariad, the five-thousand-or-so-year-old sorceress Polgara falls in love with Durnik, a thirty-something blacksmith she meets while hiding out on a farm with the prophesied saviour of the world. When it comes to the crunch, an actual God questions the wisdom of such an imbalance of power in a relationship, and asks if Polgara would limit herself to Durnik's level for the sake of love. She says yes, expecting to become a normal woman, as Durnik is a normal man. Instead, Durnik is made a sorceror.
- In A Discovery of Witches Verin, a vampire and her human husband Ernst, Marcus a vampire and Phoebe a human Until Phoebe decides to become a vampire, Stephen Proctor's father a wizard and his mother, a human.
- Wizards of Waverly Place: Because it is illegal for wizards to marry non-wizards, Jerry gave up his powers to be with Theresa.
- In Ghost Whisperer, Melinda can see ghosts, while Jim has no known power whatsoever. They're married.
- Harvey and Sabrina have this type of relationship in Sabrina the Teenage Witch. At one point, he leaves her, but that was because he learned she was using magic to mess with his life for years. To Harvey, Sabrina being a witch was not by itself a dealbreaker. Sabrina herself is the result of a union between a warlock and an ordinary woman.
- In H2O: Just Add Water, the main characters are mermaids and over the course of the show, they had relationships with ordinary men. This has caused problems, but one of them at least was a trusted Secret Keeper who was very helpful to them.
- Bewitched is a sitcom about a muggle-mage marriage between Darrin and Samantha, respectively. It's complicated by Sam's family being a long-lived Witch Species with a general Screw the Rules, I Have Supernatural Powers! attitude to modern society, Darrin's superpowered Obnoxious In-Laws, and Darrin himself being a stolid type who Does Not Like Magic and treats his devoted wife's powers as an inconvenience.
- Comedy series I Dream of Jeannie runs in a vein similar to that of Bewitched: Major Nelson is a normal human American astronaut who encountered an ornate bottle upon returning to Earth. The bottle contains the lovely Jeannie, a Sealed Good in a Can genie, who once loosed, becomes smitten with Major Nelson, whom she calls "Master." Though Nelson appreciates Jeannie and all she can do, his position necessitates maintaining The Masquerade that Jeannie is a normal fiancee, which gets complicated by her unfamiliarity with modern devices and social customs, as well as being a Clingy Jealous Girl.
- In Medium, Allison, the titular medium, is married to a normal man named Joe.
- Charmed, the main characters are witches who had many relationships with ordinary men. They weren't always successful, but Paige and Henry are doing fine, although the comic book continuation showed them going through a rough patch.
- Dragon Age II:
- Hawke is a child of Leandra Amell, a muggle, and Malcolm Hawke, a renegade mage, who eloped with her to Ferelden. Mage-muggle romances are actually quite common in the Dragon Age series, despite a heavy social stigma on dallying with mages (magic is viewed as evil by the dominant religious groups and children of mages are more likely to develop magical abilities themselves), although most end in a lot more tragedy than Malcolm and Leandra's (he died of natural causes after raising three kids with her).
- Naturally, a mage PC (Warden, Hawke, or Inquisitor) can invoke this by romancing a non-mage love interest.
- In several Harvest Moon games, such as Harvest Moon DS and Harvest Moon: Animal Parade, the normal human farmer protagonist can woo and marry a witch or wizard.
- El Goonish Shive had, at least for a while, Elliot and Sarah in a relationship. Sarah had no magic, while Elliot can shapeshift and uses martial arts styled after anime and manga.
- In The Order of the Stick, the Insufferable Genius wizard Vaarsuvius is married to a baker, though the relationship suffers from Vaarsuvius being much more invested in their pursuit of arcane power than in their spouse. Ultimately, the baker files for divorce.
- In Avatar: The Last Airbender and its sequel, The Legend of Korra, there are a lot of romances between benders and non-benders:
- In the original series, there's Zuko and Mai on the main cast.
- In the sequel, there's Tenzin and Pema, Mako and Asami, and as of the finale Korra and Asami.
- In Ben 10, Grandpa Max's wife is a magical alien named Verdona. This is where Gwen got her magical talent from.
