- Badass Crew: Before long, Touya's party is a Battle Harem consisting of himself (the resident Person of Mass Destruction) and a large number of battle-competent women. Even the girls with little to no combat experience (such as Sue and Lucia) start undergoing training to be useful to him and not fall behind the other girls.
- Battle Harem: All the girls in Touya's harem are quite competent from the beginning with some form of combat or show definite potential soon after joining it, such as melee weapons, elemental magic, bows and arrows, or piloting Magitek mecha. Their abilities keep improving thanks to constant training, being cherished by Touya (who is evolving into a demigod) and tutelage from gods in disguise that join his household.
- Empowered Badass Normal: After Touya accepts their engagement, all of the girls receive a ring that has spells like Accel, Transfer, and Storage enchanted onto it (along with other spells which complements their specific styles). He also replaces their weapons with Mythril versions and even later, by Fraze versions. This turns the Badass Normal girls like Yae, Hilda, and Lucia into Lightning Bruisers of mass destruction that can cut through rock and metal and strike with thousands of pounds of force.
- True Companions: It isn't long before they all meet that they'd give their lives for one-another. This becomes especially true after all of the girls become engaged to Touya. At that point, they all see each other as family.

The main protagonist of the series. He was an Ordinary High-School Student that was accidentally killed when God dropped lightning on Earth. As a result, he has been granted a second chance at life in a magical world, along with new abilities for both himself and his smartphone.
- The Ace: Invoked by God as part of his deal to compensate for the blunder which costed Touya his life. Touya demonstrates his capability of using all seven elements of magic (an affinity for three elements is rare and six is completely unheard of, but being able to use anybody's null magic is Beyond the Impossible).
- Achilles' Heel: Touya only has two major weaknesses: Defenses like Anti-Magic and barriers, and Mana Drain abilities. Granted, these are all dangerous to anyone, but the latter is especially risky because he has such high mana levels that if he fails to notice it's being stolen before it's too late, his opponent will be nigh-unstoppable. Fortunately, those high mana levels also means it takes a long time to adversely affect him.
- All-Loving Hero: Touya is characterized by a tendency to help anyone in need, no matter how big or small the issue. He'll help lost children find their parents, teach people to make ice cream to have something for dessert, beat up petty thugs, solve an attempted murder mystery, defend a town from a dragon (and help rebuild it afterward), adopt an orphan, and take on an entire army to rescue someone in need. He expects absolutely NOTHING in compensation and will attempt to refuse it. It's this unwavering generosity that causes the girls of his harem to fall madly in love with him.
- All Your Powers Combined: Thanks to God, Touya is reborn with the ability to use all seven elements of magic. Where Null magic is concerned, he can use any known manifestation of it, which are otherwise unique to their users. In comparison, Linze can use three, which is already considered a rare talent.
- Badass Longcoat: Touya gets a stylish white one with a powerful enchantment which increases his resistance to magic he possesses an affinity for, while it at the same time it'll doubles damage he takes from magic the wearer doesn't have an affinity for. As he can use all seven elements, there's basically no downside.
- Beware the Nice Ones: Touya is one of the kindest and nicest people imaginable, but even he has his limits.
- Shortly after he and Elze became engaged, he came across some knights who ridiculed him for his low birth. Then one commented that Elze was probably in General Leon's bed "moaning like the lowborn dog she is". Touya immediately knocked out several of the boy's teeth, proceeded to easily crush all the others with him and then turned back to continue beating the first guy before Lyon and the deputy general, Neil, stopped him. He himself admitted that the moment they insulted Elze, his vision just went red and he completely lost it.
- When Prince Zarun chooses Sue to be his wife, Touya is naturally concerned about the rumors of him being a rapist, pedophile and sadist and thus decides to go to that Prince's kingdom and observe him. Touya watches with pure rage as he learns that everything he'd heard is only scratching the surface, and the Prince is even worse than he feared. After being defeated, Zarun screams at Touya that one day he'll take revenge on all of "his women", and Touya quickly takes out Brunhild and shoots the Prince in each of his limbs one-by-one. With real bullets.
- He demonstrates how dangerous and terrifying he can be if sufficiently pissed off when he comes across a group of men running a slavery ring by posing as adventurers. That was already enough to aggravate him, but then one of them demands he hand over Leen to be sold off. The exchange ends when he casts a curse on these men that even Touya admits easily qualifies as a Fate Worse than Death.
- Just in general, really. He's a really Nice Guy, but he's also a force of nature you really don't want to mess with.
- Boring, but Practical: Touya utilizes his "Slip" spell quite a few times. Most of the time it's used for comedic effect, such as tripping a Jerkass, but it also comes in handy when he and the girls end up fighting a dragon. He also later creates a Gun Blade which can turn into a revolver or a sword for situations where he may not have enough time to cast spells.
- Can't Get Away with Nuthin': On numerous occasions, Touya tries to hide something from his fiancees, but gets found out and punished. The first time was when he hid from them the secret of the Fraze and Babylon, for fear that it would worry them. Yumina figured out he was hiding something and made him confess. Later, he also tries to hide the fact that the gynoids told him he was destined to have 9 wives, and when the gynoids tell the girls and they found out that he knew, they are not happy and tell him to STOP hiding important things from them. He still doesn't learn his lesson and gets found out a third time after Leen makes a private Love Confession. After that, there's all kinds of romantic tension between the two of them, and the Brides figure it out. Once again, they aren't happy about being kept out of the loop.
- Clueless Chick Magnet: Touya is incredibly dense when it comes to figuring out that his harem are interested in him, which they are more than happy to lampshade. He is aware of Yumina's interest, but that's because she's spelled it out for him on multiple occasions (his reaction is to try to brush her off or change the subject, though her age may have something to do with that).
- Combat Pragmatist:
- Touya has no issue with using spells like Slip, Gravity, or Gate to defeat an enemy without them ever having a chance to fight back.
- He also is very big on the idea of minimizing the likelihood of injury to himself or his comrades, now or later. When a group of thug adventurers tried to attack him over a little grudge, he hung them naked on the side of a road, took a picture and threatened to post it all over town, just to be sure they wouldn't try and attack him or the girls again. Then when he found another gang that tried to attack his bedridden comrades over the same insult, he strung them up the same way on the other side of the road.
- He creates a Gunblade in a fantasy world, meaning he is literally bringing a gun to sword fights.
- He later upgrades is Gunblade, Brunhild, to fire bullets enchanted with Paralysis, meaning any shot is an instant One-Hit KO.
- Commitment Issues: Touya doesn't see himself as professionally or emotionally ready to commit to a relationship. Thus, when someone proposes marriage to him, he becomes woefully uncomfortable. It's only through encouragement from a literal Love Goddess as well as the pleading of his suitors that he eventually agrees to Marry Them All.
- Companion Cube: As his special request, Touya elects to take his smartphone with him to the fantasy world.
- Cosmic Plaything: The Goddess of Love tells Touya that she has a particular interest in him. Rather than make people fall in love, her sphere of influence simply sets up situations where parties are likely to fall in love or deepen already-existing feelings. Thus, Touya making contact with so many beautiful girls, in situations that are almost guaranteed to make them fall for him, is largely her doing.
- Covert Pervert: Touya's imagination triggers when he learns that slime-type monsters can dissolve clothing, and he later realizes that his Aports spell can steal the underwear off a girl's body - though the Silhoueska twins make sure he promises not to do that.
- An interlude featuring Karen also revealed he has bought at least one porno magazine.
- Deity of Human Origin: Touya was a deceased human who was resurrected as a demigod.
- Divine Date: All of his love-interests technically count as this, since Touya is actually a demigod.
- Don't Call Me "Sir": Touya expresses this trope basically word for word when he hires his butler, but said butler insists on it, if only out of professionalism.
- Dramatic Slip: One of Touya's favorite uses of Null Magic is the humble Slip spell, which he puts to a lot of uses, both in combat or just for his own amusement.
- Easily Forgiven: Enforced by his grandfather, who taught him to be forgiving of others' mistakes.
- Establishing Character Moment: His very first scene has him politely converse with God after his accidental death. He is exceptionally calm and positive about it, demonstrating how kind and dutiful he is.
- Fatal Flaw: Touya's only real character flaw is his insecurity and indecisiveness when it comes to love and romance. He does not understand why anyone could love him, and thus doesn't believe he would be able to keep their love. For this reason, his brain will perform all kinds of mental gymnastics to believe an obvious romantic gesture had no romantic implications at all, and he'll often say or do the wrong thing at the wrong time and wind up hurting someone's feelings. Don't take our word for it—this diagnosis comes from the literal Goddess of Love herself.
- Fish out of Water: Touya is reborn in a fantasy world, but still has access to Earth via his smartphone. Though God tells him he can't interact directly with Earth, Touya is still able to access the internet and use apps such as one that allows him to see people on a local map.
- For Happiness: Because Yumina sees Touya as someone who brings happiness to everyone, she becomes attracted to him.
- God in Human Form: Touya isn't just a human with exceptional powers God's "upgrade" turned him into a bona-fide demigod.
- Good Flaws, Bad Flaws: Touya has a number of character traits that can equally be called positive and negative.
- Touya is nice to a fault; at one point, Elze asks if he thinks he can protect anyone by showing mercy to an enemy. Touya weakly admits that this is just who he is, and Elze acknowledges that trait as why she and Yae fell in love with him.
- Touya sticks to his principles, no matter what. While this had the benefit of winning God's favor, and also helps fuel his Nice Guy personality, it also prevents him from properly understanding or reciprocating love, because he doesn't believe he's mature or responsible enough to handle it and thus can't understand why someone could ever love him.
- Touya is a Chivalrous Pervert, insofar as he clearly finds the female body attractive and has several fetishes (namely panties) but his principles won't allow him to admit it or act on them. Because of that, he rejects any open display of affection or sexuality while at the same time secretly enjoying it.
- Harem-Powered: Touya can use any spell ever created, meaning he can use spells specific to any mages in his Battle Harem, and even combine them to create Required Secondary Powers for more complex abilities, such as Super Mode or Flight. He also gains access to the island of Babylon, which is a base created by Professor Regina Babylon to aid him in his upcoming battle with the Fraze with access to an alchemy lab, a mass-production workshop, and facilities for producing Humongous Mecha. Due to Regina's nature, each piece also comes with a Sex Bot for Touya...including Regina herself. This is on top of the fact that, as a burgeoning Demigod, Touya both receives and gives power to his wives via The Power of Love.
- Henpecked Husband: With nine strong-willed wives, this was inevitable.Leen: "It's hard to imagine you're the talented man who just annihilated countless enemies."
- The Hero: He is the protagonist, the leader of the group, the foremost adventurer and the holder of the smartphone the title refers to.
- Hidden Depths: Despite his Nice Guy attitude, he's shown to have sadistic tendency on his enemies. Almost all of them deserved it. The rest (i.e. the Black Emperor) is played for laughs and was only laughed at by Kohaku.
- Hypocritical Humor: After he learns that the king of Rynie can't raise his head against his queen, he notes to not make this happen in his household. What type of husband to his wives is he again?
- Instant Expert: After getting powers from God, Touya easily dispatches some thugs harassing the Silhoueska twins. Right from the beginning, his magic is also noticeably more potent than other magic users of his skill level.
- Marry Them All: In Volume 10, Touya turns 18 and fulfills his promise to marry each of the girls. He marries (and later sleeps in the same bed as) each girl in the order in which they were engaged to him.
- Master of All: Touya can use all magical affinities and all Null Magics, and can outdo any of his girlfriends in their own sphere of power. He's also a better fighter than Yae, the resident Badass Normal.
- Messianic Archetype: God tells Touya that he chose this world to drop him into because it was the one that needed him most. Given that, shortly after his arrival, Touya stops two assassination plots, an undead uprising, a coup attempt, and various attacks by nasty beasts, it's easy to take God at his word.
- Min-Maxing: Touya's coat has the disadvantage of doubling the damage taken from any magic that he doesn't have an affinity to. He has all magical affinities.
- Mistaken for Pedophile:
- A relatively harmless version, and Played for Laughs. On the Beach Episode, the girls confront Touya and demand to know whose swimsuit he likes best. A desperate Touya points out the first person he sees...who happens to be Sue. The other girls raise an eyebrow at his "tastes", and Touya tries to explain himself when his phone slips out of his pocket and displays a picture he took of Sue earlier (which he'd taken for purely wholesome reasons). Since the girls had more-or-less accepted that Sue would marry into the harem at some point in the future anyway, no one makes a big deal of it—they're just mildly disappointed.
- This is also a concern of Touya's whenever anyone sees him interact with Yumina, Sue, Leen, Lucia or Renee.
- Mix-and-Match Weapon: Touya uses his magical skills to craft a pistol/blade weapon he names Brunhild, even enchanting it so that it can morph between sword and gun and reload itself.
- Nay-Theist: During the Corrupt Papacy Arc, Touya states that he doesn't believe in or worship a "God of Justice" because too much injustice exists in the world, which would indicate that such a god isn't doing his job. In addition, while Touya is Pals with God, he isn't a devout worshiper and will still question both his judgment and that of other gods.
- Nice Guy: Touya wants to bring happiness to everyone, and God willingly atoned for killing Touya accidentally.
- Outside Context Magic: One thing that makes Touya incredibly powerful is the fact that all of the Null magic he learns in the story were not meant to be used by one single person, meaning that most of them have synergies that no one else would have thought of or attempted. For instance, he can use a combination of Enchant, Modeling, and Program to create a Morph Weapon, or combine Accel, Gravity, Levitate and Flight to be able to fly like Superman.
- Pals with Jesus: Touya has God on speed dial, and God willingly chats with him if advice is required.
- Paralyzing Fear of Sexuality: Touya (with help from the Goddess of Love) comes to realize that he's afraid to open his heart to someone romantically or sexually. Part of the reason stems from dissonant values between his old world and the new one; Touya has a hard time breaking modern Japanese courtship habits. Another reason is because deep down, he's insecure and fears that he's unworthy of being loved. This is a far greater problem, because it renders him unable to understand others' feelings and what factors attract them to him, leading to various misunderstandings.
- Person of Mass Construction: By combining various Null spells, his smartphone, and eventually the manufacturing facilities of Babylon, Touya can create pretty much anything in large quantities, as long as he has blueprints (often found on the Web) and sufficient raw materials.
- Person of Mass Destruction: In conjunction with his smartphone and his Multiple magic, Touya can single-handedly annihilate an entire army of undead samurai.
- Power Copying: When Touya observes someone using a new spell, he's often able to copy it, and in some cases, puts it to better use than the original caster, such as when he learns the "Program" skill from Leen to make a Gun Blade weapon, while she seemed to use it to animate a teddy bear and a chair.
- Principles Zealot: Touya sticks to the morals he was taught in the other world come hell or high water. He declines to try wine at one point because he's a "minor" (confusing Yumina, who'd never heard that term), tries to decline marrying Yumina because he'd be too young in Japan, delays marrying his brides because he feels he's too young to handle it responsibly, and other such situations. The story sometimes treats it as a "character flaw" on his part, but that is somewhat inconsistent.
- Reincarnate In Another World: God offers Touya a second chance at life by resurrecting him in a fantasy world.
- Relative Button: NEVER mock or even threaten to do something to his waifua. Getting threatened by him is the nicest punishment you'll get.
- Reluctant Ruler: Touya is offered to inherit the rule of Belfast, but turns it down. Later, as Touya becomes more and more powerful a player on a global scale, the kings of Mismede, Belfast and Regulus realize that Touya marrying both princesses of the latter two countries would result in political strife amongst the other countries. Therefore, he is given his own independent nation, which he names the Brunhild Dukedom, and despite the name, he is still referred to as a king. He still reluctantly takes the position, but grows into it.
- Ship Tease: Aside from his standard love interests and suitors note , Touya also has very ship-teasing moments with several other ladies.
- Charlotte gets very excited around Touya, especially when discussing his magical abilities or teaching him spells.
- Renee is around the same age as Sue, and seems extremely pleased to be praised and patted by Touya. When Karen (the Goddess of Love) starts giving out advice on how to seduce Touya, Renee was listening very closely.
- Tsubaki blushed profusely during their Headbutt of Love and didn't put up much of an argument when "Touya" (actually Leen) groped her.
- Cecille easily managed to bring Touya's attention to her breasts, and he very much noticed.
- A tribal princess named Pam leaps onto Touya and bites him on the neck to choose him as her mate. Later, she tries to get him to impregnate her, but she's found of being unworthy of that, or any kind of relationship with Touya, by the Bride Conference because she doesn't actually love him.
- Luna Triaste is a mad, sadomasochistic assassin and master of the purple crown who becomes obsessed with Touya, leading her to become an ally.
- Stock Light-Novel Hero: Touya Mochizuki takes the trope to an extreme. He's an Ordinary High-School Student who dies and gets transported to another world, acquires a Badass Longcoat, and quickly becomes a Showy Invincible Hero with a harem. Unlike many shows of this type, however, this is the entire point—God feel guilty for killing him before his time and actively works to give Touya the best life ever, with nigh-unbeatable power and an endless supply of women willing to share him in marriage.
- Spit Take: Happens when Yumina declares that she wants to marry him.
- Super Empowering: By utilizing the Enchant and Program spells, Touya can give his friends and allies weapons and accessories empowered with a variety of spells that improve their abilities immensely. Later, he even becomes able to power them up directly, by becoming a Demigod.
- Super Mode: His demigod form.
- Superpower Lottery: Touya was essentially granted this from God for his accidental death on Earth. Not only is he able to utilize all forms of magic, his spells are often more powerful than the other characters. Additionally, thanks to his knowledge from Earth, as well as his smartphone with internet access despite living in a medieval fantasy world, he also has abilities the others can only dream of, such as using an app to see how many people may be surrounding him, or looking up the recipe to make ice cream. Or when he creates a gun that can also turn into a sword if needed.
- Think Nothing of It: Touya almost always refuses compensation for his good deeds (sometimes using the exact phrase), and tells people he's just glad he could help. This response, in fact, is what cemented Yumina's love for him. While watching him, she quickly learned that he was kind and wise, but refusing her father's attempts to reward him just sealed the deal.
- Touched by Vorlons: As an apology for accidentally killing him, God sends Touya into a new world with an entire host of elite abilities, such as increased physical strength, agility, senses and intellect, as well as the ability to use any form of magic he chooses and virtually infinite mana. Later chapters reveal that he's become a Demigod.
- Unfazed Everyman: Touya immediately accepts his death without much issue and doesn't seem all that shocked that meets God and later gets reborn in a completely different world.
- Unorthodox Reload: Touya's revolver can only hold six bullets like a normal one. However, he enchants it with a magical program which causes the spent shells to quickly eject themselves, while new rounds are quickly loaded in to minimize the reloading process.
- Unwanted Harem: Touya seems Oblivious to Love, which the girls lament and point out repeatedly throughout the show.
- World's Best Warrior: Touya eventually becomes one of only two Gold-ranked Adventurers in the world—the other being Hilda's grandfather. And even then, there's no real contest between the two.
- Would Hit a Girl: Touya is willing to smack Leen in the head, though in her case she more than had it coming.

- Establishing Character Moment: When Touya helps her and her sister deal with thugs that have cornered them in an alley, the camera cuts back to reveal that Elze has taken out at least one on her own. A helpless Damsel in Distress she ain't.

- Boobs of Steel: Yae is one of the group's front-line fighters and the bustiest of them.
- Establishing Character Moment: Her first few scenes have her state she angered criminals by beating up some of their gang, having her dispatch most of them until hunger takes over, then choose to help Touya and the Silhoueska twins out of obligation for their help. This tells you everything you need to know about Yae in a few minutes.
- Gibberish of Love: Yae's romantic quirk is that she becomes extremely nervous and barely able to speak when she's around Touya. At one point, she almost squeezes poor Kohaku to death after she inadvertently calls Touya "beloved" and spouts high-speed gibberish trying to rationalize it.

Yumina Ernea Belfast
Voiced by: Marika Kono (Japanese), Felecia Angelle (English)
The princess of Belfast, who falls madly in love with Touya in their very first meeting. After proposing to him almost immediately, she joins his party as another adventurer. She is the first girl to start Touya's harem and is the one who suggests it to the rest.
- A-Cup Angst: 12-year-old Yumina was NOT happy when the "Bust Slimes", which like to attach to flat chests and make them look bigger, leaped straight at her while ignoring all the other girls. The slimes never stood a chance.Yumina: "I'm still growing..."
- Birds of a Feather: She finds a great friend in Lucia, due to how similar they are in age, appearance, demeanor, and upbringing.
- The Chick: Yumina is extremely observant and sensitive to the feelings of other people (possibly because of the powers of her eye). She notices that each of the other girls are falling in love with Touya, despite their attempts to hide it. When they're depressed, she can also determine what kind of assistance they need and manipulate things to fall in place exactly as she needs them to.
- Clingy Jealous Girl: Downplayed. Yumina becomes absolutely livid when another girl steals Touya's Sacred First Kiss, shouting "Even I haven't done that!" and feeling undermined as his (first) legitimate fiancee. When Lucia first shows up, Yumina is clearly jealous that she's no longer the only princess in Touya's life and quickly makes sure Lucia knows exactly who's in control. On the other hand, when she learns that the other girls in their group love Touya, she's happy about it and deliberately makes arrangements for all of them to become brides. She also tells Touya that she doesn't care if he has a handful or dozens of concubines—but he had better take care of and love all of them. You could say Yumina doesn't mind to share Touya as long as everyone agrees she is number 1.
- Covert Pervert: Turns out that Yumina is well-versed in yaoi erotic literature.
- Death Glare: After Touya brings Princess Lucia to his home from the Regulus Empire, he finds Yumina staring at the two of them from around a corner.
- Detect Evil: Yumina's Mystic Eyes can tell whether or not someone is evil. This starts to come in handy when the party starts getting involved in more and more ambiguous and delicate situations. To determine if a stranger is trustworthy, they simply ask Yumina to watch them for a while and render a judgement.
- Don't Call Me "Sir": Despite being a princess, Yumina insists on being referred to by name by the rest of the party.
- Establishing Character Moment: After meeting Touya's party, she insists on joining them on equal footing as an adventurer and stating that she's confident in her combat skills. Then, when trying to convince Touya to call her Yumina instead of "Princess", she first refers to him as darling. When he objects to that, she implies that she'll only stop if he calls her Yumina. Touya's reaction shows that he knows he's been outwitted by this 12-year-old.
- Guile Heroine: Yumina is only 12 years old, but is incredibly crafty. Her status as the princess has given her amazing diplomatic skills and persuasiveness. This is shown in rapid succession in Episode 12, where she first tricks Touya into stating his true feelings for Linze while Linze is hidden in the room, and then gives Yae and Elze the confidence to confess their feelings by sparring with Touya—something they can both understand.
- Harem Seeker: When she learns that the other women love Touya, she is delighted. Afterwards, she began actively working to make sure her future husband is surrounded by women who love and care for him. When Touya himself screws something up by ignoring or hurting someone's feelings, Yumina uses her wits to clear up the misunderstandings and pull the girl back into the harem. She states that the reason is because she wants her future husband to be surrounded by people who support and love him in ways she can't.
- The Heart: After Yumina falls in love with Touya, her number one priority becomes doing whatever it takes to support him and nurture his growth. Because she sees her fellow brides to be essential to that purpose, she'll also support and nurture them as well. The other girls notice the lengths that Yumina is willing to go to support Touya and acknowledge that her love probably outweighs all of theirs.
- Heteronormative Crusader: When Sushie innocently suggests a relationship with one of the girls, she states that it's not proper. Rather downplayed compared to Touya though, since, as opposed to his instances bordering on Have I Mentioned I Am Heterosexual Today?, Yumina only did so once, and both she and Su know they're both straight.
- Living Lie Detector: Yumina's Mystic Eyes can see a person's true character, and also whether or not they're hiding something. She can't, however, know what they're hiding. When Touya discovers a particularly Awful Truth and considers hiding it from his friends to avoid worrying them, he feels Yumina staring at him like the way they first met. She asks him what he's hiding, and a dejected Touya realizes it'll be impossible to lie to her when she's his wife.
- Love at First Sight: The second Yumina laid eyes on Touya, she was stunned. After he saved her father, she was head-over-heels. In fact, this example is more literal than most, because Yumina possesses the ability to see a person's true character. The second she saw Touya for the first time, she knew he was special.
- Magical Eye: Yumina's magical sight, which enables her to see into a person's true character. It's also why her parents have no issues with her wanting to marry Touya despite having just met him.
- Magnetic Girlfriend: Taken Up to Eleven with Yumina. Getting engaged to Touya did wonders for his love life. Her parents providing him with a mansion prompts Touya to admit he loves the girls equally, and clues Yumina in that a Marry Them All solution is possible.
- Mark of the Supernatural: Yumina's right eye is blue, while her left one is green.
- Not So Above It All: When Francesca french-kisses Touya, the normally calm and unfazed Yumina becomes livid. She flat out faints at the mention of children being conceived.
- Passive-Aggressive Kombat: As an especially crafty diplomat, Yumina is good at undermining other people without making it too obvious. For instance, when she meets Princess Lucia for the first time, she happily greets her fellow Princess and casually mentions that Touya is her fiance. It has the intended effect.
- Preemptive "Shut Up": When meeting Tokugawa Ieyahsu for the first time, Yumina introduced herself and then introduces Touya as her future husband. Touya starts to object to that, but Yumina turns around and stares at him. That shuts Touya right up.
- Top Wife: The first girl to start Touya's harem and generally acknowledged as the one to love him the most. When Touya does indeed Marry Them All, Yumina becomes the chairman of the "Bride Conference" where she calls the girls together and offers them positions as Touya's brides, and every time an issue occurs in which the girls become more uncertain, she calls them together again to see where they stand on the matter.
- Yaoi Fangirl: She is implied to be one of these when she demonstrates knowledge of the contents of a particularly racy yaoi series, though she insists that she only knows about it because she knows the author, a fellow princess who is rabidly fanatical about the genre.

A court magician who is centuries old and extremely gifted in magical ability. She takes an interest in Touya after noticing his skill in magic and travels with him to discover and learn new things. She is the eighth girl to be inducted into Touya's harem.
- Ambiguously Bi: She straight up gropes Tsubaki during their first meeting (and pretends to be Touya while doing so), and there's very heavy BDSM undertones between her and Charlotte. Despite that, she also becomes one of Touya's wives.
- Court Mage: She was the court mage for the Kingdom of Mismede before meeting Touya. She later becomes the Court Mage of his Dukedom instead.
- Did You Just Have Sex?: After she and Touya bust up a ring of slavers, they return home very late and are questioned by the Bride Conference on what they were doing all that time. Leen's face turns beet red and she can barely speak.
- Dirty Old Woman: Of the main characters, she is by far the most perverse and sexually-aggressive. Only Regina Babylon and her gynoids top Leen's libido.
- Double Standard: She calls out Touya when he's hesitant to use his mind-reading ability (which requires a Headbutt of Love) on an aged man, when he did so eagerly with young women.
- Elegant Gothic Lolita: She wears very frilly clothing and carries around a parasol.
- The Fair Folk: She is an actual member of the Fair Folk species, and is just as mischievous as legends would indicate.
- The Gadfly: Leen is one of The Fair Folk. When she teaches Touya about the Recall spell and asks him to look into Yae's memory, she says that the ideal form of physical contact is a kiss. Cue massive blushing...Leen: I'm joking.
- Glamour: She keeps her wings invisible in order to blend in with humans.
- Immortality Begins at 20: Fair Folk stop aging at some point between puberty and mid-adulthood. Leen is an example of the former.
- It Amused Me: She likes to travel with the party, and mess with them, because they never cease to amuse her.
- Marriage of Convenience: After Touya finds the Library, Leen asks him to marry her. Touya accuses her of marrying him to access the Library, guessing that it was her main goal all along, but she denies it and says that she's always loved him—the Library is just a bonus. Touya isn't convinced she's telling the truth. Later, the Bride Conference figures out what's going on and conducts an interview before Leen can officially become a fiancee. They show the same suspicions towards Leen's motives, but Leen firmly states that she truly does love Touya. Yumina carefully gauges Leen's statement with her eyes, and then gives Leen her approval.
- The Mistress: Subverted. After Touya is reluctant to marry her, Leen says she'll take the position of Mistress if she has to, but he eventually agrees to marry.
- Not Growing Up Sucks: Leen, being forever stuck in pubescent body, says that she's never married largely because she was either mistaken for a child or only attracted the attention of pedophiles.
- Not So Above It All: Leen is extremely lewd, and often called out the other girls when they became clingy and jealous toward Touya. After she declares her love for him, though, she becomes a nervous wreck when asked what she and Touya were doing alone until morning.
- Parasol of Prettiness: She carries it around, completing her appearance as an Elegant Gothic Lolita.
- The Professor: She's an academic and seeker of knowledge, as well as a magical instructor.
- Really 700 Years Old: Leen estimates that she is 612 years old.
- The Smart Girl: She's the most intellectual of the main party, as well as the most experienced.
- The Tease: As part of her Gadfly tendencies, she loves to flirt...especially with Touya.
- Winged Humanoid: She has fairy wings, but keeps them invisible so that she blends in with human beings.
- Yaoi Fangirl: If the way she reacts to Touya and Baba's Headbutt of Love (It Makes Sense in Context) is any indication.Leen: "What a wonderful view!"

- Antiquated Linguistics: Uses the archaic, feminine "warawa" to refer to herself.
- Arranged Marriage: When Sue turns 11, a foreign prince picks her for a wife. Neither Sue nor her father are happy about it, not just because Sue loves Touya, but because the prince in question is a known rapist and pedophile. Sue begs Touya to marry her first.
- Damsel in Distress: Twice. Once when Touya saves her from a kidnapping attempt, and again when a foreign prince demands to marry her.
- Everyone Can See It: Absolutely everyone knows that Sue is in love with Touya...except Touya. When she's formally announced as the sixth bride, the Conference barely has to vote on it because everyone saw it coming. Except Touya.
- Genki Girl: Very energetic and friendly. In addition, she is one of the few girls that isn't (normally) shy about her feelings for Touya. Sue proudly makes her feelings known to anyone and everyone.
- Like Brother and Sister: At one point, Yumina refers to Sue as "the Fifth Candidate" (for a bride), and Touya dismisses the idea, believing that Sue just sees him as a big brother. Yumina sighs.

- Only Known by Their Nickname: She prefers to go by "Sue" to virtually everyone.
- O.O.C. Is Serious Business: During the Yuuron Invasion Arc, Touya is blamed for the destruction of an entire city as gambit for political rivals to gain power. This pisses Sue off, who advises Touya to go to war and wipe them all out. When he shows concern about Sue's anger, she tells him that at times like this, a ruler has to get angry or no one will take him seriously.
- Precocious Crush: Heck, at one point, she flat out refers to Touya as "my future husband".
- Rescue Romance: It's very subtle, but it is there. From the moment they met, Sue had plans to marry Touya, and her father was in on the plan, too.
- Token Mini-Moe: One of the youngest characters in the show, and definitely the youngest of Touya's brides.

Voiced by: Yuki Kaida (Japanese), Marissa Lenti (English)A large white tiger spirit formerly known as the "White Emperor". She became the first of the Divine Beasts to acknowledge Touya as their master.
- Butt-Monkey: Kohaku is constantly getting the breath squeezed out of her when whoever's carrying her is under stress.
- Cuteness Proximity: Kohaku thinks that she'll be less conspicuous as a Cute Kitten than as the Royal White Tiger. Unfortunately, she assumes this form in front of Touya's harem. They all immediately lose their minds over her, dealing a near-fatal blow to her dignity. This is later exploited in an attempt to get a crying girl to calm down so she can be taken home; when a fluffy white cat asks her name, what little girl won't answer?
- The Four Gods: The Expy of Báihǔ / Byakko.
