[[caption-width:383:Left to right: [[{{Badass}} Mamoru]], [[WaifProphet Haruka]], [[GadgeteerGenius Igawa]]]]
{{Badass}} [[BlindWeaponmaster blind swordsman]] Mamoru Hijikata is out doing some field testing on his new sonar shades, when he encounters Haruka, who asks him to protect her. Noticing all the men after her, he agrees and asks her how long this'll take. She responds with:

''[[TitleDrop "Until death do us part."]]''

This isn't by chance, as Haruka is revealed to have the ability to [[OracularUrchin see the future]]. [[ScrewDestiny To escape from her fate]], she has to stay by his side until she's free. The on-going series is all about her [[EarnYourHappyEnding fight for a]] {{happy ending}}.

Not to be confused with the [[TheSixties '60s]] British sitcom ''[='Til Death Us Do Part=]'', which spawned the US adaptation ''AllInTheFamily''.

NeedsABetterDescription

-----
!!This series provides examples of:
* ActionGirl: Sierra and Juliet. Ashford as well.
* AffablyEvil: Mister Wiseman is very courteous towards guys who would be his enemies. He's also a college professor and criminologist when he's not plotting against people.
* AnArmAndALeg: Often inflicted by Mamoru.
* AnOfferYouCantRefuse
* AntiHero: Mamoru. People wonder if he was hired to fight the criminals so that, even if he died, there would be one less evildoer in the world.
** Mamoru is clearly disgusted by people and acts that most would agree to be clearly evil though. It is less about him being evil as it is him finding it hard to bend over in order to be a saint, as being saints seem to be policy within the Element Networks.
* AnyoneCanDie: [[spoiler:Detective Genda]].
* ArmorIsUseless: Mamoru stabbed a guy through a [[UpToEleven tank]]. You cannot get better armor than that.
** Though his katana CAN cut through anything, So... justified?
** Considering that he cut through the carbon fiber armor of Fang's "Beast," slicing through an outdated tank is nothing. However, since he couldn't cut through Tate's titanium alloy arm, the "Beast's" armor was probably of the weaker variety or was very thin, as allotropes of carbon are the "strongest" materials ever produced by man.
* ArtificialLimbs: Tate's metal arm is his primary weapon/defence. [[spoiler: Edge steals an upgraded version of Tate's arm ]].
* AttackDrone: Fang uses special remote drones with sound dampeners so Mamoru's eyes can't detect them.
* BackToBackBadasses: [[spoiler: Kaiser and Jesus]].
** [[spoiler: Genda and Tate]].
* {{Badass}}: Most of the cast.
* BadassAndChildDuo: Mamoru and Haruka
* BadassBiker: Dai Ibuki. However, he's only badass when he's on his bike, so....
* BadassBoast: Mamoru seems to like this trope.
--> "This blade is specially made. Anything that stands in its way will be cut in half. Anything." (Also note that this could be Mamoru talking about himself rather than the blade that he carries.)
** In one notable instance, he pulls off what can only be described as a [[HandicappedBadass Handicapped Bad]][[BadassBoast ass Boast]]:
--> "If you turn your inept killing intent towards me now, no matter who you are, I'll cut you to pieces. Whether you've got a weapon or not... even if I'd be fighting an old man or a woman or a child... I can't go easy on them, either. Seeing as I can't check with my eyes, that is."
* BadassGrandpa: Zelm looks old enough to at least have grandchildren, but he's the one who taught Trump all their techniques. The few times he's fought so far, his killing method is so invisible that it hasn't even been revealed yet.
* BadGuyBar: The "Nest of Geese" that Jesus and Wiseman hang out is one of these.
* BankRobbery: They come across one being done by the infamous "Five Minute Gang", named so because it only takes them that long to rob a bank.
* BearsAreBadNews: And thus, Mamoru [[spoiler:decided to make Haruka fight one as part of her training.]]
* BerserkButton: You do ''not'' want to [[http://www.mangafox.com/manga/until_death_do_us_part/v11/c093/13.html look Mamoru in the eye]] when he's dealing with [[spoiler:the man who got Haruka's parents killed, and ruined her chances of a happy life]] -- or anyone else who caused her (or other innocents) harm, for that matter.
** [[spoiler: Manga/{{Jesus}} carries over his BerserkButton from the series he's originally from. Threaten his students and you'll pay for it.]]
** [[spoiler: Genda and Aegis]] both get pissed when a raging [[spoiler:Edge Turus]] declares Haruka, the girl whose life he's helped to ruin, is his property and he will not let anyone take her. They share the same look of rage and charge right at [[spoiler:Edge]] to deliver a brutal CurbStomp on him.
* TheBlacksmith: We have not met him yet, but someone is making Mamoru's molecule thin sword. We do see a note from him though.
* BlessedWithSuck: Haruka; sure she can read the future, but it caused her parents' death and she cannot even go to school without people watching her all the time to ensure that she does not get kidnapped.
* BlindWeaponmaster: Mamoru
* BloodKnight: Mamoru. Upon meeting Aegis, who was apparently sent to help Haruka, Mamoru said that he wanted to fight him no matter what since he hasn't met anyone who could fight him head on.
* BodyguardCrush: Not yet, but it is implied that it will happen eventually because...
** WifeHusbandry: Inverted? Haruka says [[spoiler: that she and Mamoru will be married one day,]] and she's doing everything she can to make it happen. Mamoru knows nothing about this and Igawa and Sierra were asked to keep quiet about it.
** Apparently Mamoru knew about it and [[spoiler: agrees to marriage]] if they survive the current battle.
* BrokenBird: Juliet [[spoiler:lost her uterus when she was raped some time back, so she can't have babies.]] This explains why she's usually such a {{Jerkass}} to Sierra, [[spoiler:who laments quite a bit about her dead daughter.]]
* BulletCatch: Done by guy known as [[RedBaron "The Shield]] [[YamiNoAegis of Aegis"]], although we find out that he has a mechanical arm that helps him do that.
* TheButcher: Fang, Edge Turus's brother and hitman. He got his name for his crime scenes looking like someone had been ripped apart by wild animals.
* CarFu: With a motorcycle; for added fun, [[UpToEleven it's his only weapon.]]
** Igawa is not bad with his vehicles either, but not to [[CrazyAwesome Dai's insanity]].
* CarnivalOfKillers: One of these shows up after a one hundred million dollar bounty is placed on Mamoru's head.
* CharlesAtlasSuperpower: [[ImplausibleFencingPowers Mamoru's sword skills]]. 15 hours/day as a kid.
* ChekhovsGunman: Remember [[http://www.mangafox.com/manga/until_death_do_us_part/v01/c001/17.html her]]? One panel of kind-of-flashback in the first chapter? Turns out she's [[spoiler:Luna, unmasked, and probably also the last thing Mamoru ever saw with his own eyes, right before she very messily died.]] ''Nobody'' [[DidntSeeThatComing saw that coming]].
* TheChessmaster: Mister Wiseman, Tatsumi Daiba, Zelm.
* ChildSoldiers: [[spoiler:The children that the [=TPC=] kidnapped who remained unsold were raised to be soldiers for the ''Canes Venatici''.]]
* CleanCut: So clean that the intermolecular forces can hold the object together afterwards.
* CloseCallHaircut: Tate, [[http://www.mangareader.net/until-death-do-us-part/112/6 here]].
* CodeName: Aside from The Wall, there's also "Blade" (Mamoru), "Needle", and probably others we haven't seen yet.
* CoolBike: Dai's custom motorcycle, ''Bucephalus'' .
* CoolOldGuy: Wiseman and Zelm.
* CoolShades: To hide Mamoru's eyes. They also allow him to see.
* CoolSword
* {{Crossover}}: [[YamiNoAegis Tate]], Manga/{{Jesus}}, and [[http://www.mangaupdates.com/series.html?id=32514 Daiba]] all have their own series. [[spoiler: Liu Yijian and Dragon Gate organization also appeared in Tate's series.]]
* CynicismCatalyst: Sierra and Kilo's daughter was killed before they joined The Wall. Also Igawa's sister and Aegis' family.
** [[spoiler: Genda's death for the entire group]].
* DeathSeeker: The ''Canes Venatici''. Mamoru noticed that they are quick to kill their own and felt that their {{super soldier}}s fought like they wanted to lose. [[spoiler:This owes to the fact that they're the unsold products from [=TPC=]'s operations that were kept and raised to be soldiers, and were addicted to a certain drug to ensure loyalty.]]
* DisabilitySuperpower
* DiplomaticImpunity: Edge Turus. Does not help him much...
* TheDreaded: Zahiid Turus, Edge and Fang's father, along with many others. He rules his own country.
* DrivesLikeCrazy: Igawa, although it's more of he needs to drive like crazy rather than he just does.
* ElitesAreMoreGlamorous: The Wall for starters. And the Black Unit.
* EnemyOfMyEnemy: The reason why the various mercs going undercover in the school aren't killing each other yet. See EnemyCivilWar for more details.
* EveryoneCallsHimBarkeep: Excluding Alpha [[spoiler: Jack Garvey]] and Sierra [[spoiler: Serena]], the names of the Wall members are unknown, and they're only ever referred to as their code names.
** Also, Jesus's real name is unknown by anyone.
* EnemyCivilWar: In terms of spying on [[spoiler:Haruka and all when she gets in school with Mamoru and meets Jesus. They're the Public Security Intelligence Agency, 24 (A reference to the actual 24?) and the Galboan Black Unit.]]
* EvilCripple: Edge. When first introduced he was just evil; [[AnArmAndALeg Mamoru added the "cripple" part]].
* EyeScream: Ever wonder what happened to Mamoru's eyes? [[spoiler:He was right next to somebody when they were hit with an exploding round.]]
* FamilyUnfriendlyDeath: The series as a whole isn't shy about killing people, but it's taken to a different level when you see [[spoiler:Luna getting blown up.]]
* MrFanservice: Quite a few female readers started the series, simply because Mamoru is hot.
** As far as that goes, most of the male cast has a small amount of fangirls. Even Senji.
* GadgeteerGenius: Igawa and [[ProfessionalKiller Fang]]. Also possibly, Tatsumi Daiba, the manager of the Element Network, who created a search engine [[TeenGenius when he was a teenager]] and has developed a quantum computer and a sentient AI.
* GambitPileup: Wiseman has his own plans and is putting Mamoru's in to motion, maybe. Haruka has a plan that she is getting The Element Network to put into motion for her. Last but not least, Daiba has his own plans in the work. Just about all of them are revolving around Haruka.
* GeniusCripple: [[spoiler:Daiba]]
* TheGift: Mamoru is described as having it by his old master and many others.
* GogglesDoSomethingUnusual
* GoodIsNotNice: Mamoru. He may fight crime, but he's openly admitted to only doing as such so he can continue to fight and hone his skills. YMMV slightly though, as he has toned it down a little from the start of the manga.
** Also, Jesus, maybe even more so than Mamoru. Sure, he went [[spoiler: to Chechnya to search for his missing student, he saved some of the kids from the Canes Venaciti, and he got rid of Orion.]] This doesn't stop him from [[spoiler: warning Haruka that if she or Mamoru get in his way, one or both of them will die by his hand.]]
* GoodScarsEvilScars: Mamoru has an antihero scar covering half his face from what blinded him.
* HandicappedBadass: Mamoru, whenever he doesn't have his glasses or when they're not working; with his glasses, he doesn't really count as "handicapped"
* HeelFaceTurn: Senji Tamagawa, although it's arguable if he was ever a Heel, even though he was part of the gang who works under Edge.
* HugeGuyTinyGirl: The difference is already big as Mamoru's an adult and Haruka's just a pre-teen, but the former is around ''6 ft. tall''.
* HumanResources: How bio chips are made. Except not just any humans, [[PoweredByAForsakenChild fetuses]].
** Also, the TPC, who kidnap children for forced organ transplants.
* ImplausibleFencingPowers: Mamoru, although this is helped by his AbsurdlySharpBlade. Although he could cut bullets in mid-flight before that.
** Made a little bit more plausible by the fact that his glasses allow him to see where a gun barrel is pointing and just as likely is able to tell when someone is pulling a trigger, therefore all he has to do is make sure his blade is in the way, rather than reacting to the bullet itself.
* ImmuneToFate: The biggest reason that Haruka needs Mamoru.
* InHarmsWay: Mamoru says his job fighting is the only reason why he is alive.
* InverseLawOfSharpnessAndAccuracy: Mamoru only misses against a plot important character. Although it is implied that he is going easy on them.
* TheJailBaitWait: Not that Mamoru is invoking the trope himself but if Haruka's premonition about their marriage holds true, which it likely will, then the start of any real intimate relationship between the two is most likely waiting on this. [[spoiler: In a side chapter, it reveals the vision Haruka had of their marriage featured a visibly aged Haruka, who had to be at least in her late teens or early twenties.]]
* KatanasAreJustBetter: Mamoru, even before he lost his eyesight. Despite being trained with firearms, his drive has always been for the blade.
* KnifeNut: Kilo
** On some occasions, Mamoru will throw a few knives around as well.
* LethalJokeItem: A bouncy ball? Aw, you can't hurt me with that- *broken bones*
** Same goes for that mercenaries colleague, who uses a boomerang. Now the boomerang used to be a hunting weapon, but it still doesn't seem very serious a threat.
* MadeOfIron: Mamoru gets shot a few times, cut up, fights all night, and he is perfectly fine the next day. His injuries never seem to stick longer than the current fight.
* MamaBear: Sierra to Haruka.
* MarriedInTheFuture: Part of the point of the story is that the heroine, who is [[PsychicPowers precognizant]], saw a future where she was married to our main AntiHero, and she really wants that to come true.
* MasterSwordsman: Mamoru and Genda.
* MeaningfulName: Mamoru means "to protect". Guess what his job (other than beating the hell out of bad guys) is.
* [[spoiler:MercyKill]]: [[spoiler:Mamoru to Luna.]]
* MissionControl: Igawa.
* MoodWhiplash: Chapter 72 somewhat resembled a sketch from WesternAnimation/TomAndJerry, until it gets to the end...
* {{Mooks}}: Very few die, but many are taken down.
* MookHorrorShow: One page in chapter 93 gave off this feel.
* MoralityPet: Haruka to Mamoru in many respects. The first couple chapters Igawa kept reminding Mamoru not to kill guys because it would make Haruka sad.
* NewTransferStudent: Haruka herself at times; also, [[spoiler:Anna.]]
* NiceHat: Pyro
* NightmareFace: [[http://www.mangafox.com/manga/until_death_do_us_part/v13/c107/22.html here]]. Only to be expected, as the person [[spoiler:''suddenly exploding'']].
* NoCelebritiesWereHarmed: Zelm looks remarkably similar to MorganFreeman. The fact he seems to be stoic and authoritative further increases the resemblance.
* NoMisterBondIExpectYouToDine: [[spoiler:Orion]]
* NonLethalKO: Sometimes taking a guy down in a nonlethal manner in this story involves cutting out his [[BodyHorror lower teeth]]....
* NotWearingTights: What we have here is, essentially, a blind Franchise/{{Batman}} with a katana. This couldn't be ''not'' awesome if it tried.
* OldMaster: Inaba.
* OmniscientCouncilOfVagueness: The Element Network. Their vagueness is also what prompts Mister Wiseman to deviate from his job of just killing Mamoru to finding out everything he can about them.
* OracularUrchin
* ParentalAbandonment: Haruka and [[spoiler: Daiba; in fact it's why he made The Element.]]
* PlotRelevantAgeUp: [[spoiler:Anna seems to be at least a couple of years older from her YamiNoAegis appearance]].
** To be fair, in [[spoiler:YamiNoAegis' sequel, ''Akatsuki no Aegis'',]] she is already considerably older.
* PostVictoryCollapse: Mamoru at the end of the Chechnya arc.
* PrivateMilitaryContractors: The Wall.
* PrecociousCrush: Haruka to Mamoru. He does not know yet, but she really wants to marry him. [[spoiler: Except he does know and in fact guessed that was the case a long time ago.]]
* ProfessionalKiller: Jesus, the world's top hitman, and Fang.
* PropheciesAreAlwaysRight: Averted, and played straight at times.
* PutOnABus: Sierra and Kilo were injured and put in a hospital to recuperate. [[spoiler:A recent chapter has Sierra fully recover and try to find Haruka, and in a much later chapter (after the TimeSkip) she goes to train under a swordmaster who helped Mamoru.]]
* RedOniBlueOni: Dai and Mamoru have this dynamic
* [[spoiler:RedemptionEqualsDeath]]: [[spoiler:Luna]]
* ReplacementGoldfish: Sierra treats Haruka like her own daughter, [[spoiler:who she mentions would have been the same age had she not died.]]
* RevolversAreJustBetter: Jesus uses a .357 Colt Python.
* RunningGag: Mamoru can and will sleep anywhere at anytime, usually getting astonished looks because of it.
* ScrewDestiny: The whole story is Haruka's struggle to do just that.
* ScrewTheRulesIHaveConnections: Subverted, the guy who tried to use this trope got his limbs cut off.
* SharpenedToASingleAtom: Mamoru's katana, of the single molecule wide variety.
* ShoutOut: Mamoru defeats [[spoiler: the leader of Canes Venatici]] with a technique from [[LoneWolfAndCub Suio Ryu]].
* SinkOrSwimMentor: Mamoru during the time skip when he is training Haruka, paraphrase: dodge the bear or get eaten by a bear.
** To be fair, Mamoru stood by completely supervising the training to ensure Haruka was not harmed at any time.
* SmokingIsCool: Genda. Most notably [[http://www.mangafox.com/manga/until_death_do_us_part/v07/c049/7.html when he fights]] Mamoru head-on in pitch darkness, all the while puffing away.
* StepfordSmiler: Haruka becomes one after she is forced to leave school again.
* SunglassesAtNight: Justified on multiple counts; see CoolShades.
* SweetTooth: Mamoru and Ibuki.
* SwordCane
* TankGoodness: Brought out by Wiseman to fight Mamoru.
-->'''Senji''': Holy shit.
* TenMinuteRetirement: Mamoru and Haruka left for about a month and came back. When asked what he's been doing since he left, Mamoru just says "I took a stroll."
* ThemeNaming: The Wall uses the MilitaryAlphabet to name their operatives.
* TitleDrop: In the first chapter, no less.
* TookALevelInBadass: Subverted with Edge. He stole an upgraded version of Aegis' arm and complemented it with Fang's drone controller. He still got pummeled.
* TricksterMentor: Mamoru is accused of this by Haruka with his interactions with Dai.
* WaifFu: Justified, female The Wall operatives are trained paramilitary, and Haruka can take advantage of the fact that she can read the future. The latter TookALevelInBadass [[spoiler:after being trained by Mamoru to fight '''BEARS'''.]]
* WaifProphet
* WhatTheHellHero: It's because of Mamoru's decidedly criminal-like behaviour with enemies that Sierra is so unwilling to leave Haruka with him, and others have a hard time trusting him.
* WholeEpisodeFlashback: The Next arc.
* {{Yakuza}}: Mostly as {{Mook}}s, but a few (Komura, Senji) end up becoming more important characters.
* YourHeadAsplode: A number of terrorists have explosives implanted in their molars. Guess what happens when they bite down on them. [[spoiler:It can also be triggered remotely.]]
