** [[spoiler:Eventually, thanks in part to his familiars

* EroticDream: Louise is mentioned to have had one about Saito in Chapter 23.

* EveryoneCanSeeIt: Both Louise and Emereldas can tell that Siesta has it ''bad'' for Saito. The main reason that he hasn't done something is that he doesn't want to take advantage of her, and wants more than just sex from a partner.

* HonorBeforeReason: When Kirche tells Saito that her family would never learn another branch of magic other than fire because of their pride in their fire magic, even if that magic is complementary like wind (because that would be like admitting that their fire magic isn't good enough), Saito responds that that line of thinking is patently ridiculous in his world, [[HadToBeSharp on account of the war against Black Star, the loss of Void magic, and other changes forcing them to accept practicality over pride]], and that the mages from his world who had reacted with stubbornness when they had to change due to the lack of Void magic (mostly people like Kirche's family that had a history of specializing in one element) were either killed off by more pragmatic enemies or else forced to retire if they still refused to adapt.

* {{Polyamory}}: A subplot is Saito building up a harem. He hasn't slept with anyone yet, but he is protective of Louise and Siesta. Future members include his familiars Emereldas and Kaede, and Henrietta.

* WrongContextMagic: Saito and Johann, being from a world with different rules for magic, are able to constantly confound the natives of Halkagenia.

* RealityEnsues: Accidental or not, drugging the princess's sworn liegeman is an ''extremely'' serious offense. Montmorency only avoids a life sentence, by virtue of both already planning to brew an antidote as well as several other mitigating factors.

* NotSoDifferent: Louise feels this way about Saito when she hears about his difficulty with fire magic, feeling like she finally has someone who understands her own magical issues.

** Emereldas's father was half [[Manga/RosarioToVampire Onimodoki]].

** Saito is only a newly-accredited Onmyoji. However, due to a number of different factors, he's able to go toe-to-toe with some of the most powerful and skilled Halkaginian mages. This is actually becomes the reason why Kaede/Gin'yoku wants him to stay in Halkegenia, as Saito could become independently powerful and influential to the point of gaining a Grant of Nobility, while on Earth all the increased ability he's gotten from his time off-world would get him is a promotion to a rank where he'd be actively put into danger from Juxtaposed Black Star.

* ObstructiveBureaucrat: The Church likes the status quo, and will often do its best to impede any mages that actually research magic and try to improve the way it's practiced instead of just ruling over their lands. Colbert is lucky to have Henrietta's support, otherwise, they might even try to vilify him as a revolutionary and radical in order to discredit his research. They've also done their best to keep Henrietta from obtaining the Prayer Book, made sure that the countries of Halkegenia remain separate kingdoms despite the blood ties between their rulers (like having the arranged marriage between Henrietta and the Germanian Emperor specify that the firstborn will become the Tristainian throne and the second child will become the Germanian heir), which is noted by Osmand as likely related to keeping the Familiar summoning spells distinct, and may have covered up human familiars belonging to royals in the past.

* NormalFishInATinyPond: Saito is only a newly-accredited Onmyoji. However, due to a number of different factors, he's able to go toe-to-toe with some of the most powerful and skilled Halkaginian mages. This is actually becomes the reason why Kaede/Gin'yoku wants him to stay in Halkegenia, as Saito could become independently powerful and influential to the point of gaining a Grant of Nobility, while on Earth all the increased ability he's gotten from his time off-world would get him is a promotion to a rank where he'd be actively put into danger from Juxtaposed Black Star.

** Wardes may be a traitorous regicide, but even he believes they are lines that you don't cross, and touching certain {{Berserk Button}}s is one of them. He's also very critical of Cromwell's excessive use of the Ring of Andvari.

* EvenEvilHasStandards: Johann perfectly agrees with the Onmyoji on disliking the Black Stars, viewing them as arrogant and fanatical fools.

* NormalFishInATinyPond: Saito is only a newly-accredited Onmyoji. However, due to a number of different factors, he's able to go toe-to-toe with some of the most powerful and skilled Halkaginian mages. This is actually becomes the reason why Kaede/Gin'yoku wants him to stay in Halkegenia, as Saito could become independently powerful and influential to the point of gaining a Grant of Nobility.

* NormalFishInATinyPond: Saito is only a newly-accredited Onmyoji. However, due to a number of different factors, he's able to go toe-to-toe with some of the most powerful and skilled Halkaginian mages.

* WhamLine: Saito drops this bombshell when he figures out what's wrong with Louise's magic.

* AlwaysLawfulGood: The onmyoji of the Divine Ministry in Saito's world drill ''hard'' in the ethical use of magic during training, to where Johann considers them frustratingly moral.

* DramaPreservingHandicap: Johann can't combine his stolen techniques because the families he stole them from tended to feud, and thus made sure that they were incompatible with each other (for example, one family devised a method for creating a [[AttackOfThe50FootWhatever giant Jewel Knight]], while another had a means of summoning two at once, so he can't summon another Knight while he has the giant one out.) Saito is glad that he never got the chance to obtain the [[Manga/ChronoCrusade Harvenheit Family]]'s research and bypass this limitation.

* {{Familiar}}: Saito may be Louise's Familiar, but as an onmyoji, he himself has Familiars of his own, and more than one at that: [[HornyDevils Emereldas the succubus]] and Urajirosatoukaede the {{Oni}}. The greatest onmyoji in his own world, Abe no Seimei, had ''twelve''.

* YourCheatingHeart: Guiche keeps sleeping around on Montmorency. Thanks to Halkaginian social standards, it's the fact that he's started sleeping with other mages that bothers her – she's fine with dalliances with maids, in part because she knows it's not a threat to her social standing if he knocks a commoner up, and partially because her own father sleeps with his maids and he has at least one illegitimate daughter and another child on the way from the same woman.

* OverprotectiveDad: Kurotama, Urajirosatoukaede's father, doesn't like his daughter's growing romantic feelings towards Saito. Fortunately, his wife is able to keep his protectiveness in check. [[spoiler: Unfortunately, the clause he forced into Saito's familiar contract with his daughter leads to Wales being killed because he is only allowed to summon her for a limited time, and Saito plans to renegotiate the contract as soon as he is feasibly able]].

* MyGreatestFailure: Saito and Louise took losing [[spoiler: Prince Wales to Wardes, [[HealingMagicIsTheHardest and the]] [[WorfHadTheFlu circumtances]] [[DramaPreservingHandicap behind]] [[PowerStrainBlackout it]] really hard.]]

* OverlyLongName: "Urajirosatoukaede" is quite the mouthful. Thankfully, Saito is allowed to just call her "Kaede".

* AppealToTradition: A common argument against new spells is the old "good enough for our ancestors, good enough for us" idea.

* AutomaticCrossbows: Saito gets one. He uses it for the first time against dragon riders on their way to Albion.
** He later gives it an enchantment to automatically reload it.
** The bolts themselves are also enchanted with wind (for increased range), fire, and ice charms.

** The differente colored tribes of Oni all apparently have different skills, strengths, and weaknesses. For example, White Oni are [[GlassCannon experts at all forms of weaponry but are more delicate]], Black Oni are [[SquishyWizard geniuses in magic but have low stamina]], and Red Oni exemplify DumbMuscle.

* EvilVersusEvil: Minister Richemont hints that Reconquista is plotting to get rid of the individual who attacked the castle (not knowing it's Johann von Leopold), viewing them as a potentially dangerous variable who could scupper their plans if left to their own devices.

* HybridPower: Kaede inherited the weaponry InstantExpert ability of the White Oni and the Black Oni's skill with magic at about 3/4 the skill level of her parents, as well as the Silver Oni PerceptionFilter ability.

* IKnowYourTrueName: Knowing the true name of a person gives complete knowledge of every facet of their being. Learning someone else's true name allows a magic user to control them with the right ritual, while knowing your own true name makes you stronger because of the knowledge gained. Demons are unique in that it's possible, though difficult and time consuming, to change their true name.

* MamaBear: Karin, big time.
* ManOfKryptonite: Jewel Sorcery was develop partly as a countermeasure against devils and demons. Because of this, they're basically useless against jewel golems, which purify their magic and absorb it, adding it to the caster's own. Since Oni are partly demonic in origin, the same applies to them.

* MedievalStasis: Both Halkagenia's technology and magic are far behind Earth's; Osmond theorizes it's in part because, with the Church (which is highly conservative in nature) mediating between the countries, they haven't had any large-scale wars in millennia, causing the development of magic to stagnate. Whereas on Earth, there are numerous magical factions at war with each other, which, combined with the desire to keep up with technological advances, has led to constant innovation. For example, what Halkagenia considers the best locking spell in the world, Saito considers remarkably simple.

* SexGod: Emereldas is described as being a goddess of the sexual arts. Justified, since she's a succubus.

* SoProudOfYou: After reuniting with her daughter, Karin is so proud of how Louise dealt with Johann that she commissions a custom swordwand for her, a family tradition and honor that neither of her sisters have earned.
* TheSpartanWay: Onmyoji training is grueling and rigorous and starts relatively early compared to Halkagenian mage training, but the results speak for themselves. Saito is the same age as the students at the academy, yet is already a recently graduated and fully-accredited Omnyoji who can hold his own in a fight.

* UnskilledButStrong: Because Halkagenian mages have more natural ambient magic to work with, their spells tend to fall into this when compared to the WeakButSkilled magic Saito and other Earth mages use. It certainly doesn't help that most focus on power rather than control, and the lack of innovation doesn't help either, with Saito baffled that they don't even have any spells to measure magical potential (or even a proper term for it), for example. Saito even says that without his talismans using ambient magic to boost his spell-power, he'd be unable to even boil water using the Halkagenian system. Colbert plans to use Saito's knowledge to help revolutionise Halkagenian spell structures through mimicry of how his spells absorb ambient energy.

* YouAreBetterThanYouThinkYouAre: [[spoiler: After she gets back from Albion, Louise [[MyGreatestFailure blames herself]] for Wardes managing to steal the letter and fatally stab Wales. Agnes firmly reassures her, pointing out that she did the absolute best that she could, even getting Wales to flee Albion with the Royal Guard when it became clear that the situation was untenable, and that with Wardes massively exceeding her own skill level in both magic and swordplay the fact that she was injured to the extent that she was proves how much she struggled, as well as the fact that Wardes' experience as a Crown Agent meant that there was likely nothing that she could have done to stop them from ambushing her. Rupert then chimes in and points out that she actually managed to stab the traitor in the shoulder, and Henrietta makes it clear that Louise is ''not'' at fault for what happened and won't be punished for it, swearing it on her royal name, every Noble in the room echoing it and making it law]].

** Johan is a similar case.

** Due to the differences in magic between the worlds, Saito states he's roughly half as strong as the average student but he's still a fully accredited magic-user. Osmand is fairly surprised to hear that, according to a scan of both Saito and Colbert's magical reserves taken after Fouquet's attack, Colbert had ''ten times'' the amount of magic that Saito did, given Saito's feats, and even asks Colbert if he's sure that the difference between himself and Saito is really that substantial.

* MundaneWish: After saving Princess Henrietta's life, Saito asks for a house as a reward. Given that he could have asked for almost anything except a noble title, and there several places just lying around that she can give to him, it's not a terribly large reward.

* IWantMyBelovedToBeHappy: [[spoiler: As he lay dying, Wales makes Henrietta promise that she will find someone else one day.]]
