History Manga / TheTitansBride

** In the manga, Koichi is transported to Tildant while [[ADateWithRosiePalms in the middle of getting himself off]]. Right into the middle of a crowd. Caius even makes a point of commenting on how small Koichi is and how cute he finds ''it''. In the anime, Koichi is just lying on his bed when he gets transported and it's just Caius who greets him when he arrives.

* SexualExtortion: Averted; Rail makes it clear to Koichi that this trope is ''not'' his intention when he [[spoiler: asks to conduct some research on the other's body. But given the nature of Koichi and Caius' request, Rail states that he will need to observe first-hand how Koichi reacts to various forms of pleasurable stimuli]].

* SurprisinglyRealisticOutcome: Since Caius is a literal giant, it stands to reason that his... equipment would be just as massive. Koichi is ''terrified'' when he sees just how big it is and cries at the thought of having to take all of that in. [[spoiler: Both Caius and Koichi eventually seek out a member of the [[OurElvesAreDifferent Long-Ear Tribe]] to see if there is a way to shrink Caius' size so that he can fit completely inside Koichi. Alternatively, after learning Koichi can tap into Caius' magic, he could utilize magic to increase his capacity.]]

* WistfulAmnesia: [[spoiler:After Koichi is retgoned, his friends from his original world feel his absence, particularly his best friend Jin, as well as Anzu, his crush who reciprocated his feelings.]]

* ConvenientlyAnOrphan: Both of Koichi's parents are subject to DeathByOriginStory. This was likely to mitigate the obvious FridgeHorror that would come from the story ending with [[spoiler:all evidence and memory of Koichi's existence being permanently erased from the timeline of his old home world so he can live happily ever after with his Isekai husband]].

* {{Wolfman}}: Baro is one of the anthropomorphic varieties.

* FisherKing: The leaders of each of the species are the conduits between the people and their god, and a nation will suffer if the leader fails to promote their species' fundamental trait. This is given multiple times as a reason Caius is unfit for the throne: [[spoiler: first because prophecy forbids him from pairing with any of his own people, second because he isolated himself for years in search of a way around the prophecy.]]

* DarkSkinnedBlond: All of the titans have blond hair and brown skin.

* AmbiguouslyBrown: The giants all have a noticeably tan skin-tone compared to Koichi. Koichi immediately recognizes Caius as a foreigner based on that alone.

** The anime cuts out the rather suggestive massage Caius gives Koichi in chapter 4 and 5 of the manga. Oh, and the sex that happened after.

* {{Wolfman}}: Baro is one of the anthropomorphic variety.

* AmicableExes: The only reason why Caius and Medina's engagement got dissolved was because of the oracle's prophecy. Even long after they broke off their engagement, here's no hard feelings between the two, and both still deeply care for one another.

* HeroicBSOD: Chapter 77 reveals that the ominous prophecy that left Caius unable to wed anyone in his world had affected him more badly than anyone realized, as he spent at least a year in a state of depression.

* TheImmodestOrgasm: Koichi is not exactly what one would call quiet during sex, but it's not hard to see why he's unable to keep his voice down.
* ImpossibleTask: The [[spoiler: bridal quiz that Koichi has to undertake to prove his worth as Caius' bride]] requires him to figure out how to successfully [[spoiler: hatch a stillborn child of the Hubbard royal family. At least, Naiad thinks this to be the case as all the people of Hubbard have been trying to have the egg hatch countless times for a whole year but to no avail]], so there wouldn't be any reason to believe that Koichi, a human from another world, would be able to pull it off.

* LoopholeAbuse: The Oracle stated that Caius could never marry someone from Eustil, so he summons someone from another world to be his bride.

* LoveTriangle: Seems to be set up with the arrival of Medina, Caius original bride-to-be. She acts incredibly antagonistic towards Koichi and it's heavily implied she still has feelings for Caius. [[spoiler:It's completely subverted by chapter 9. As it turns out, Caius' sister noticed Koichi wasn't feeling quite certain about the wedding and intentionally called Medina over to make Koichi jealous.]]

* TheAce: Koichi. In his own world he was a star athlete, the captain of the basketball club and immensely popular with the ladies.
* AllLovingHero: Koichi is a very kind young man who can't stand the thought of causing trouble for others. [[spoiler:In Chapter 22, he stops Caius from killing Palo (who had previously kidnapped and molested him) because he can't bear the thought of someone getting in trouble or even dying because of him.]]

* AmicableExes: The only reason why Caius and Medina's engagement got dissolved was because of the oracle's prophecy. Nonetheless, there's no hard feelings between the two, and both still deeply care for one another.

* HotBlooded: Naiad is passionate, not afraid to speak her mind, and pretty quick to anger, especially when her twin brother.

* ImpossibleTask: The bridal quiz that Koichi has to undertake to prove his worth as Caius' bride has him find a way to successfully hatch stillborn child of the Hubbard royal family. At least, Naiad thinks this to be the case as all the people of Hubbard have been trying to have the egg hatch countless times for a whole year, to no avail, so there wouldn't be any reason to believe that Koichi, a human from another world, would be able to pull it off.

* LoopholeAbuse: The Oracle stated that Caius could never marry someone from Eustil. So he summons someone from another world to be his bride.

* NaughtyBirdwatching: Rail did explain that he has to observe Koichi and Caius doing it so that he can be able to properly determine how he can help them with their sex life, though nonetheless, the trope still counts, especially when Rail starts to pleasure himself while watching the other two get at it.

* OfficialCouple: Caius and Koichi are the manga's main couple. Heck, the series starts with them getting engaged, though only one of them knew of it beforehand.

* OurElvesAreDifferent: Elves in Eustil represent the trait curiosity and are known for being great scholars and scientists. They’re stated to have low sex drives except during their breeding season which is about a month every three years.

* RetGone: Due to how summoning magic works in Eustil, the circumstances of Koichi's presence ends up poking a hole in the dimensional "wall" between his home world and Eustil that keeps the worlds separate and stable. It takes one month for it to repair itself, but it also means he would need to make a very important decision: leave Caius behind and return home, or form a contract that would also essentially rewrite history to where Koichi died young in his original home. [[spoiler:He heavily considered going back home due to his sentimental ties with his mother and classmates, but ultimately stays with Caius.]]

* SexualExtortion: Averted; Rail makes it clear to Koichi that this trope is ''not'' his intention when he asks to conduct some research on the other's body. But given the nature of Koichi and Caius' request, Rail states that he will need to observe first-hand how Koichi reacts to various forms of pleasurable stimuli.
* SuccessionCrisis: Although it's not the Vistaille siblings who are fighting amongst each other for the throne; rather, it's the royal court who doesn't approve of Caius having a male bride and wishes for Naiad, Caius' younger sister, to take the throne instead. However, Naiad is against the idea and is enraged even that her brother has to face this problem.

* TokenHuman: Humans do not exist in Tildant. Koichi is the only member of his race to live there.

* {{Wolfman}}: Palo is one of the anthropomorphic variety.
