The following is a list of characters and tropes that apply to them in Maoyuu Maou Yuusha:Sorted by English Name / Japanese Name (due the characters having titles as names, different translations are bound to happen, so the original Japanese names are placed for consistence).
The male lead protagonist. A young and powerful human warrior, he came to the Demon World to end the evil of the demons by killing their leader, the Demon Queen. Instead, he learns the harsh reality the Human/Demon war was never a battle between Good and Evil but a period of turmoil where both weak, innocent humans and demons are oppressed and taken advantage by the corrupt and powerful from both sides. Wishing to end the war the right way with the least repercussions, he agrees to become the Demon Queen's ally in her plans to stop the war.
A Lady on Each Arm: As the Demon Queen puts it, he should feel blessed when Lady Knight and her barge into his bedroom (okay, Head Maid pushed them in) and end up like this. He instead feels like in a Lover Tug of War.
A Man Is Not a Virgin: Inverted. Despite his battle prowess he is a virgin and shy around girls. Head Maid regularly reminds Demon Queen of this fact.
Bad Ass: The Hero is basically unstoppable, and every fight he takes part in rapidly becomes a Curb-Stomp Battle in his favour. This includes battles against entire armies.
He's so Bad Ass, that in an alternate universe proposed by Demon Queen, she was the Hero of the Demon World, sent to plead her case to Hero, who would be the King of the Human World who would have all but levelled the Demon World.
Black and White Morality: The Hero used to believe that the humans were good, demons were bad and he can solve the world's problems by defeating the Demon Queen but....
Character Development: He later realizes how naive he was and starts to wise up and gets rid of his earlier misconceptions.
Black Knight: After wearing the Demon Armor given to him by the Demon Queen, he becomes the Dark Knight, her enforcer in the Demon world.
Book Dumb: While he admits he never had a proper education until the church taught him, he's still smart to know about human politics and is willing to learn new things.
Celibate Hero: He's seemingly somewhat dense over the Demon Queen's advances on him and is sometimes shy about it. Same with Fire Dragon Princess, Demon Girl and Lady Knight. He eventually admits that it is because he wants to avoid a Mayfly-December Romance with Demon Queen.
Like A Married Couple: Since the Hero and the Demon Queen belong to each other, he is technically her "husband". They even act like a married couple. A sweet, (mostly) innocent, wide-eyed married couple.
Lonely at the Top: In at least one of the manga adaptations, Archer points out that Hero is so strong that he's effectively completely removed from humanity in term of capacities and thus can't really have allies in battle, because anyone fighting alongside him will at best be irrelevant, at worst a burden.
Magic Knight: Is not only a good swordsman but a magic user as well like teleportation.
Nice Job Breaking It, Hero: When the Demon Queen is overtaken by the bloodthirsty spirits of her predecessors, he is able to save her and exorcise them... at the cost of shattering the magic warding off their tomb forever and unleashing them onto the world.
No Guy Wants to Be Chased: He calls a "Strategic Retreat" (with great panic) using teleport magic to get away when Grand Princess Fire Dragon (suggestively) invites him to "escort her" back to her "lavish hotel room".
One-Man Army: Was able to infiltrate the Demon Queen's castle and fought her minions all by himself! Later it is stated that no matter how many, or which army the Hero may face, he will win against it.
He eventually battles the possessed Demon Queen and the ghosts of pretty much every previous ruler of demonkind at the same time. Except it's not really a fight. It's him kicking all their asses simultaneously, then snapping her out of it.
The Paladin: A non religious type. While he does believe in the Spirit of Light, he's not as religious as Lady Knight.
He also destroys the Demon World gate, as well as a mountain at different points in the story, with little indication of any serious effort on his part. In fact he often shows he had to hold back when doing that level of damage, suggesting he could have done much more.
Physical God: He´s pretty much able to fight every other person in the world at the same time and win.
Secret Identity: To protect his reputation and hide the fact he was the Hero who fought the Demon Queen, he goes by the title "The White Swordsman". In the Demon Lands he goes by as Dark Knight, The Dragon to Demon Queen.
Stepford Smiler: Before he met the Demon Queen, Hero was never sure of his feats really making people lives better, and that was gnawing at him but never let it show.
Story Breaker Power: Seriously, if he ever fought with anybody, he's guaranteed to win. He could go solo against any army in the world, and he'd win. The one thing stopping him of course, is his will to help out Demon Queen's quest to improve the situation of the world.
Supporting Protagonist: Interestingly enough, he's more focused on the good and influence of the Demon Queen, and the series deconstructs that despite the fact that he's The Hero in terms of archetype with all the abilities and fighting prowess, he can do remarkably little compared to the Demon Queen which frustrates him to some degree.
Technical Pacifist: Following Demon Queen's example, Hero no longer believes fighting fixes anything.
Hannibal Has a Point: While still believing the Demon Queen was an opponent he couldn't argue against the data proving that the war has actually improved Human living overall.
The female lead protagonist. The 43rd ruler of the Demon World and the youngest to rule by demon standards, she is a powerful sorceress but has no experience in battle. Wise and smart, her vast knowledge comes from the "Exterior Library", a hidden dimension where knowledge of the past and future is kept and where her clan lived. Despite her knowledge, she is considered incompetent by the warmongering demon clans. Seeing what would happen to the war if it didn't end without the problems that it cause fixed, she awaited the arrival of the Hero so she could ask for his help to end war the right way. After finally getting him as her ally, she and the Hero travel to the Human world where she takes the identity of the Crimson Scholar, a human noble who has come to help the lower classes.
Adorkable: Can be lovably awkward around Hero. When listing her good points to him, the only thing she could think of was that she was a superb accountant.
The Chains of Commanding: She's very aware of the potential disasters her plans can bring about and agonizes over the consequences.
Clingy Jealous Girl: When Hero attempts to set out to find Witch in episode 3, Maou gets annoyed by his attempt to sneak out in the middle of the night to look for her. She also brings up Knight coming to build a convent in the village, and later when she tries to get a kiss on the lips, he kisses her on the forehead instead, earning an annoyed grunt and look from her.
In episode 5, he returns after being gone for a year. She starts smacking him with her pillow, and wondering why he was gone for so long. He tells her about his postcards, which she doesn't accept. Then when she asks him why he simply didn't just use a spell to destroy a city, Hero explains that there were many people still living there. Then he goes on to explain said people, such as princesses, bar girls, and maids, which causes her to smack him some more.
The Corruption: The spirits of the former Demon Kings possesses her briefly later on.
Demonic Possession: As part of the rites that make her Demon King, she is required to stay in an ancient tomb from time to time, which houses the spirits of past Demon Kings. She would generally visit them on frequent intervals to calm them, but after staying away for too long, they drive her out of her own body and take it over. She ultimately ends up being saved by Hero, using their vow.
Expy: While it could be accidental, She looks quite a bit like Touhou's Koakumanote Being both red-headed demons with long hair, especially in the TV series.
Faking the Dead: For about a chapter or so after she was hit with a poisoned arrow she faked her death to lure out the one responsible. The Blue Demon Clan.
Good Is Not Soft: Is she kind and idealistic? Yes. Will she stand by and let cruelty and sadness continue to exist when she has the power to stop it? Hell no.
Guile Hero: Cutting deals and propagating ideas are her weapons.
The Hero: Ironic, isn't it? Demon Queen drives the plot and sets off the heroic side's actions. He even acknowledges her as such.
Heroic Spirit: While in the Temple of the Dead with the former Demon Lords' spirits. Cruelly subverted when it actually fails her; she gets possessed by said spirits.
Hero Killer: Demon Queen's Superpowered Evil Side is the first villain who has been a legitimate threat to one of the heroes. Head Maid is certain that if Demon Queen can't regain control of herself then she won't survive another encounter.
Hikikomori: The yonkoma makes a joke about the maid treating her as one, complete with leaving food at the door. She does shut herself in with books for longer periods of time, but it's more due to just wanting to read than being reclusive.
Horned Humanoid: Her horns are pretty much the only non-human feature she has. In most adaptations, however, those horns are actually a removable hair band, which subverts this trope. When corrupted, she seems to grow genuine horns, however.
I Am Not Pretty: Thinks she's not pretty for focusing on her studies rather than on beauty however...
Iconic Outfit: Since the anime aired, a flood of fanart of her in her Demon Queen dress (which she only wears early on) began to come out, despite the fact her Scholar outfit is what she more often wears.
Innocent Fanservice Girl: At first it looked like she might just be teasing Hero, but as the story progresses it's obvious she really doesn't understand her "meat" isn't "useless" at all.
Internal Reformist: She tries first to "work within the system" in the Human lands, but becomes an icon without pretending it.
The Jail Bait Wait: Demon Queen has known Hero was her fated one since the moment he was born.
Klingon Promotion: In Maoyuu Maou Yuusha Gaiden, it is revealed she lead a coup and became the Demon Queen immediately after her predecessor, the 42th Demon King, was weaken and defeated by a group of human heroes.
It's clear that she's far below Hero and his companions though.
The Missus and the Ex: The Demon Queen is the "Missus". Unluckily for the Hero, both she and Lady Knight quickly become friends.
Most Definitely Not The Demon Queen: In the 4komas, Demon Queen is absolutely horrible about maintaining her secret identity; she frequently forgets not to wear her horn headband out in public and often refers to herself as Demon Queen by accident. Everyone in the village starts calling her Demon Queen as an endearing nickname and concludes she can't be the Demon Queen due to being so harmless and inept.
Not Herself: In several adaptations when she gets ready to enter the temple/tomb of the previous demon lords she tells Head Maid to try to strike her down if she shows any sign of this has it's a hint that the spirits of the former demon lords could try to take over her body which is what happens to her.
OOC Is Serious Business: When Demon Queen staggers out of the temple of the previous Demon Kings, her behavioral change quickly tips off Head Maid that she's been corrupted. Demon Queen's announcement that she's going to fight the humans seals it.
Outgrown Such Silly Superstitions: She is usually considered one of the most intellectual and intelligent cast members and doesn't believe in the various "spirits" of the Human faith.
The Paragon: She has a knack for inspiring people to challenge their limits and see things in different ways.
The Power Of Trust: She believes that fair deals and honoring your word is the way for a better world.
Put on a Bus: For a long time she barely appears in person; mostly in occasional flashbacks.
Queen Incognito: To hide the fact she's the Demon Queen, she takes the identity of a human noble named "the Crimson Scholar" who recently graduated from a prestigious academy.
Really 700 Years Old: Maybe not so much, but she talks about spending a hundred years studying Economy pretty casually.
In the anime adaption this is Played for Laughs when Hero first goes to attack her from behind, until she turns around and he almost lands in Marshmallow Hell, then demands she tell him where the king is.
Silk Hiding Steel: A kind-hearted girl who is willing to take a stand for her beliefs to make the world a kinder and gentler place.
Stripperiffic: She wears such an outfit when Hero first meets her, but it's only due to Head Maid's influence; Demon Queen herself dislikes dressing this way. When corrupted, she fully embraces this.
In The Comp Ace manga version when she's possessed and corrupted by the spirits of the former demon lords she goes beyond stripperiffic and actually only has a few strategically placed magical shadows covering her naughty bits and barely at that.
She learned being a maid from books. It's probably on purpose.
Jerk with a Heart of Gold: While she takes her duty as the Head Maid seriously and looks down on anyone who doesn't do their job well, she does have a soft heart when she hired the runaway serf sisters to be her assistant maids.
Two human sisters who were formerly Serfs who ran away from their lord's land due to a lack of food and harsh conditions. After being found at the Demon Queen's mansion, Head Maid wanted them to be returned but the Hero wanted them to stay so a compromise was reached where the girls became maids in the household. The older sister is called Big Maid Sister (Meido Ane) while the younger sister is called Little Maid Sister (Meido Imouto).
Badass Pacifist: In episode 9, while disguised as the Crimson Scholar, she gets whipped while giving a very emotional speech about being a human, and about the kinds of freedoms she's experienced, and passed along to others. The crowd begins stoning the church messenger instead, and when they attempt to kill her, the Winter King himself saves her.
Big Eater: Little Sister Maid. Her obssession with food isn't surprising given her backstory.
Cheerful Child: Little Sister Maid gradually comes into this trope after being rescued and serving the Demon King's household.
Jeanne d'Archétype: Big Maid Sister shapes up into this after she's forced to impersonate the Crimson Scholar to fool the Inquisition.
Only Sane Man: Big Maid Sister is the only character in the 4komas capable of properly imitating Demon Queen. For added fun, she actually portrays Demon Queen as she is in the proper story, as opposed to her incompetent Butt Monkey self presented in the 4komas.
Taught by Experience: The Sisters understand about being poor with no food very well unlike those who haven't. This comes in very handy in episode 9 when she gives her speech to the crowd of people.
Team Normal: Big Sister Maid becomes a de facto member of Demon Queen's conspiracy (to maintain the visible presence of the Crimson Scholar even when the Demon Queen is unavailable), surrounded by nobles, kings, epic heroes and demon geniuses.
The Heart: Being of humble birth, she gives a commoner's perspective to the conspirators.
This Is Something He's Got to Do Himself: Older Maid Sister is very grateful with lessons and ideas she receives from Head Maid and Crimson Scholar. That's why she indirectly refuse Hero's help during her capture by the Inquisitor while she poses as Crimson Scholar, feels that it could demean her value as human being.
A former Crusader and one of the Hero's ex-companions. After the Hero left his companions to face the Demon Queen alone, she retired as a nun back to her home village. After reuniting with the Hero, she becomes a knight again to help the Hero and the Demon Queen.
A-Cup Angst: She's clearly bothered by the fact that she doesn't...stack up...to Demon Queen. Butler/Archer's mocking of her flat chest doesn't help.
Even the Girls Want Her: After her successful Aurora Island campaign, Lady Knight finds she's accumulated quite a few female fans.
Everybody Knew Already: She was already aware of the Demon Queen's true identity before the Demon Queen confessed the truth to her.
Hopeless Suitor: When Hero praises the Demon King's motives in doing what she's doing, Lady Knight has a downtrodden look, and realizes she can't compare to her. Despite that, she still tries to spend as much time with him as possible.
Good Shepherd: A member of a religious order trying to help the poor and helpless.
Jumped at the Call: Accepted Winter King's offer to become the new Supreme Commander of the Southern Kingdoms Forces.
Keep the Reward: After the news the Hero wounded the Demon Queen, the United Kingdoms Headquarters offered the Hero's companions rewards and important positions. Lady Knight refused their offers and rewards as it was insulting and felt like stealing the efforts of the Hero's work.
Knighting: Lady Knight pledges herself to Hero and asks him to make it formal by performing the typical Hollywood short form ceremony (kneeling and being touched on the shoulder with the flat of the sword).
The Paladin: She's exactly like the Hero except she's more religious in the Spirit of Light religion.
Retired Badass: Became a nun when the Hero's gang disbanded until the Hero and the Demon Queen ask for her help.
Saintly Church: When Demon Queen asked her to start a convenant in Winter Pass to teach the locals more effective farming techniques and alleviate famine, Lady Knight says "that falls perfectly in line with our mission."
One of the Hero's ex-companions and the group's mage. Not is much known about her except that she was a skilled wizard with bad social skills but a love for books. Despite appearing Stoic, Witch Girl cared about the Hero. After the Hero was reported missing in the Demon World after his battle with the Demon Queen, she went to the Demon World to find the Hero herself and learn some new spells along the way. As a hobby, she writes her own series of light novels, "Pleasant Serial Killers". She's also the Heroine of the Spin-Off Manga Gaiden in Monthly Shonen Sirius.Is confirmed to be a demon, and is actually from the same clan as Demon Queen.
Dark and Troubled Past: She was formerly known as Silver Mage where she and her older sister White Mage and Indigo Mage were part of the Magic Association's project to create powerful Artificial Heroes which left many children dead. By the time she abandon the Magic Association and join Hero's party, both of her sister have died.
Seeker Archetype: While journeying through the Demon World, she's also learning the magics of the Demon clans. The Fairy Queen comments how talented Witch Girl is in magic.
Split Personality: Seems to have this, in the anime at the very least. There's a serious, analytical personality, a hot blooded one, and a lazy, prone to fall asleep at any time one. The former two are actually her late older sisters, White Mage and Indigo Mage who died but whose spirits inhabit their younger sister.
The Stoic: The looks she gives out most of the time, yet....
Not So Stoic: The fact she's searching for the Hero in the Demon World shows that she cares about him.
King of the White Night Nation. Formerly Supreme Commander of the Southern Kingdoms Forces before the 1st invasion of Aurora island failed which lead to the death of 6000 soldiers including the Winter King.
Dirty Coward: Ran away from battle to save his own skin, justifying it saying he was royalty.
Green-Eyed Monster: To Winter King for his successful Aurora campaign and for being left out of the alliance between the Winter, Ice and Iron Nations. He essentially sends a political lynch mob after Crimson Scholar because of it.
Jerkass: Compare to the other leaders of the Southern Kingdoms, King White Night is a insensitive jerk who has no combat experience, leadership skills and refuses to take responsibility when things go bad.
A giant demon walrus who controls the Aurora Island located south of the Southern Kingdoms. Both the Human Kingdoms and the Demon Queen want to reclaim Aurora island for different reasons respectively; it's a strategic position near the portal to the Demon World and has rich resources particular salt and fish for Fuyugoshi Village.
A Father to His Men: Despite his Blood Knight tendencies, he does care about his troops like ordering them to retreat after being surrounded by both the Winter Kingdom Forces and Crusaders and is genuinely distressed when his second-in-command is killed.
Sea Monster: Most of his followers are different sea creatures like sharks, turtles, and krakens.
The Merchants Union
The Merchants Union is a large organization in charge with the Southern Kingdoms war effort. Despite being the official war supplier for the humans, the Union has no loyalty to the human kingdoms and are only helping them for the money. The Union is a very powerful organization and to ensure they stay on top, they'll eliminate anyone who threatens their power. Their motto is: "Thou shalt be a merchant before a human, Thou shalt be a merchant before a faithful servant of the Church." Basically, they're Ferengis.
Rousseau Was Right: Despite his belief in making money no matter what, he is won over by the Crimson Scholar's wish to help end the War by peaceful means. Her altruistic ways convinces the Young Merchant to agree to help her plant corn at the other nations.
The Chessmaster: His plan to stir up economy by stockpiling consumerable, making their prices rise, and handing out bonds for payment of future harvest. At first, it seems like an attack to weaken the Southern Nations, by destroy their advantages of abundance of food, by making their supply bleed to Central. However, if you think about it carefully, those plans can also backfired toward Central, since too high prices can cause civil unrest, and with the bonds, the nobles practically sold their assets toward Union, leaving nothing for them and their subjects. You can guess what happened if people got starving but food is rare or overpriced. Either way, the Union wins.
Wacky Marriage Proposal: After making a deal for buying the Crimson Scholar's Sea Compass rights and in exchange for the Union to plant and grow Corn at the other nations, the Young Merchant admits he's smitten by her intellect and makes a marriage proposal to her. Naturally, she refuses but he won't give up as he'll try again. Too bad for him, she's already in love with someone else.
Depending on the Artist: In the Comp Ace version, he is portrayed as an older fat man. In the Comic Clear version, he is portrayed as a thin, middle aged man. The only thing common between the two is that the Middle Aged Merchant has Arabian style clothes.
Standard Hero Reward: Should the Dark Knight succeed in reclaiming Gateway City, the Archduke will give away his daughter to him as his wife/mistress/whatever. That's gonna be awkward for the Dark Knight/Hero.
Distressed Damsel: Was kept prisoner from the rebellious Black Wolf Clan before being rescued by the Dark Knight.
Turn the Other Cheek: After being rescued, she accepts the Dark Knight will give a stern warning to the Black Wolf Clan not to rebel again since she holds no grudges against the them and doesn't want any more punishment against them.
The leader of the human mercenary armies that guard a fortress outside Gateway city. Unlike his Commanding officer, the General treats demons with respect and dignity.
Know When to Fold 'Em: He peacefully surrenders Gateway city to the Demons in order to protect his men and the humans living there.
Officer and a Gentleman: The General treats demons with respect and defends Demon Girl from a group of harassing human soldiers.
Reasonable Authority Figure: He refuses to join the Commander of the Holy Crusaders abandoning Gateway city in order to protect its human citizens and is willing to uses peaceful, diplomatic solutions to keep both the human and demon citizens at peace.
The Neidermeyer: He is fooled into following the Dark Knight/Hero in circles that by the time the Crusaders reach Aurora island, the Winter Nation Forces are already attacking the South Arctic General forces and the Crusaders get decimated easily by the retreating demons due to exhaustion.
A young demon girl from the Singing Birds Clan. She was formerly a servant of Lord Wizard, a blue demon who conned the people at his village by using his birds to fake attacks while pretending to rescue them. After the Lord Wizard's con is exposed by Witch Girl, the now free Feather Girl joins Witch Girl in her journey.
Honor Before Reason: Even though she can actually fly, she refuses to do so out of respect for her clan's traditions that they can only fly after they perform a ritual for their Goddess.
I Owe You My Life: After Witch Girl rescues her from Lord Wizard, Feather Girl becomes her servant as thanks for helping.
Last of Her Kind: She is the last of the Singing Birds Clan after they were wiped out by a rival clan. This is the reason why Feather Girl won't fly since doing so without performing her clans ritual would mean the death of her clans culture and it's people.
A recurring antagonist in Maoyuu Maou Yuusha Gaiden. A mage from the Magic Association, she is ordered by the Pope to find Witch Girl and kill her so she may replace her as Hero's new party member.
Affably Evil: A fun loving girl who acts nice for a minute and the next will try and kill you.
Dumbass No More: After their training is completed. The Merchant Youngster became Winter Nation King great secretary (emphasis on great), while Noble Youngster became spy for Young Merchant and Warrior Youngster becomes a skilled tactician. Somehow, it's kinda ironic.
Only Sane Man: The Merchant Youngster seems to have comparatively more sense than the other two.
Straw Character: Warrior Youngster believes women shouldn't be warriors, thinks everyone should devote themselves for the war effort no matter the price and thinks starvation doesn't exist and it's that person fault if they're starving. It's no surprise Lady Knight, Demon Queen and Big Sister Maid have something to say about those views.
Surrounded by Idiots: Much to their teachers frustrations (Demon Queen and Lady Knight), it might take time for the trio to learn to understand why war is bad to the people and economy and let go of their old beliefs.
Took a Level in Badass: While largely portrayed as idiots early on, once the Three Youngsters graduate from Crimson Scholar's class, they're almost completely different people. Warrior Youngster becomes a master tactician, Noble Youngster becomes a talented diplomat, and Merchant Youngster becomes Winter Nation's Financial Minister.
Warrior Youngster shows just how well he's been taught, using his tactics to lead Iron Nation's reserve/volunteer army to a decisive victory over a larger and better equipped White Night Nation invasion force utilizing superior tactics. Then takes down Commander in a one-on-one fight while protecting Big Sister Maid.
Translation Style Choices: Soldier Youngster to Warrior Youngster, although this is a real change, not a choice since Gunjin does not translate to warrior at all.
