'''''Kizuna: Bonds of Love''''' (絆 KIZUNA~恋のから騒ぎ~, Kizuna: Koi no Kara Sawagi?) is a yaoi manga, authored by Kazuma Kodaka. Released in 1994 and ending with the release of the final volume in 2008, it allegedly was one of the first and most popular manga [[{{Yaoi}} to feature a homosexual relationship]]. It also spawned 3 [=OVAs=].

The story centers on the relationship between Kei Enjouji, a TallDarkAndSnarky highschool student, and Ranmaru Samejima, a HeirToTheDojo. Enjouji fell for Ranmaru almost at first sight when they were kids and he saw Ranmaru practicing his kendo moves, and started pursuing a relationship with him. Ranmaru is at first reluctant, but Enjouji perseveres and they become boyfriends anyway.

However, their relationship won't be an easy one... since after Enjouji's mother Hotaru dies, she leaves him a letter revealing his heritage. Which happens to be linked to a powerful Yakuza clan, whose leader Takeshi Sagano is Enjouji's long lost father. Enjouji and Ranmaru attempt to keep up with their lives and go to college peacefully, but the Yakuza won't leave them alone, and specially not when Enjouji's half-brother Kai takes an interest in Ranmaru himself...

!!Provides examples of:

* AnguishedDeclarationOfLove: Enjouji is good at these. Ranmaru far less so although he still has a stab at it once or twice.
* AwLookTheyReallyDoLoveEachOther: any couple will get this at ''least'' once, and Ranmaru and Enjouji have half their relationship running on it.
* BadassInANiceSuit: It's smartly dressed Yakuza and assassins. What do you think?
* BerserkButton: if you injure Enjouji, ''do not'' be in the vicinity of Ranmaru with a stick-like object.
* BigNo: Enjouji, when [[spoiler: Ranmaru protects him from the people trying to kill him and gets hit instead.]]
* BodyguardCrush: [[spoiler: Masa and Kai.]]
* BridalCarry: Enjouji carries Ranmaru back to bed this way [[spoiler: while he was in his first stages of recovery from the accident]] in the third OVA and volume.
* ButtMonkey: If something funny or humiliating's gonna happen, Enjouji is likely to be on the receiving end. Unless we count the [[spoiler: hit and run incident.]]
* CastFullOfPrettyBoys: lampshaded by the mangaka in volume 6 "Kizuna VI... the manga which has completely ignored the existence of women!!"
* CasualDangerDialog: Roy is physically incapable of ''not'' doing this. Even when there's ''no one else around!'' Oh yes, he [[ConsummateProfessional knows what he's doing]] but when he misses being blown up by about two seconds could he ''not laugh???''
* CheshireCatGrin: Enjouji's adopted one when he was a kid and it doesn't seem to be going away any time soon.
* CoolBigSis: Ranmaru's sister Yuki
** And Rena. Er... kind of.
* ConsummateProfessional: both in the Yakuza world, and that of professional killers. Roy tends to have issues with people who treat him like a rookie.
* CrazyJealousGuy: Ranmaru acts like this a bit about Enjouji, but it's nowhere near the serious extent to which Enjouji acts around Ranmaru. Apparently it's InTheBlood because Kai acts the same way around Masa. Then of course, there's Jack, who will kill you if you sleep with Roy. No, literally. He will take a sniper rifle and put a bullet through your brain if you fuck his boyfriend.
* [[spoiler: DeliverUsFromEvil]]: [[spoiler: Hotaru, though she wasn't exactly a villain.]]
* {{Determinator}}: Ranmaru. Kai also seems to learn this from him.
* TheDragon: Masanori Araki, to Takeshi Sagano. So much that he's been handpicked as Takeshi's succesor.
* EvenTheGuysWantHim: Ranmaru. Repeatedly, to the point where even his kendo club members tend to have a thing for him. Even guys trying to ''kill'' him seem to have enough time to remark on how hot he is. Although really, it's [[{{Bishonen}} not like you could blame them]].
* FacingTheBulletsOneLiner: Roy (yet again), and Enouji, when the need arises. Both of them also tend to use GallowsHumor, none of which their partners [[DudeNotFunny find funny]].
* FirstNameBasis: the principal couple, Enouji Kei (extroverted, casual) and Samejima Ranmaru (introverted, formal), normally call each other "Enjouji" and "Ran-chan". When Enjouji's half-brother Sagano Kai [[spoiler: first rescues Samejima from a drugging and rape attempt and then essentially rapes him himself]], Samejima in confusion and anguish calls him "Kei." Told about it later by Sagano, Enjouji realizes how badly Samejima was affected because "He only calls me Kei ''when he really needs me by his side.''"
* HeirToTheDojo: Ranmaru
* HeroicBastard: Kei Enjouji, who didn't know for a long time and was ''not'' thrilled when he learnt about it.
* HeroicSacrifice: Ranmaru in the form of a DivingSave.
* HitmanWithAHeart: Jack has a soft spot for innocent kids... and Roy. Falls into TheAtoner category in that he donates money to charities and orphanages as a way to atone for his career. He tends to be very much on the side of NeverHurtAnInnocent. Roy, on the other hand is more of the persuasion that [[TooDumbToLive If The Innocent Was Stupid Enough To Get Involved, It's Their Own Damn Fault]].
* HotBlooded: Kai and Ranmaru.
* HypocriticalHumor: Kai criticizes the relationship between his childhood friend Kumi and Kyousuke because of their age difference...never mind that there's a ''marginal'' age difference between Masa and himself.
** More ironically [[spoiler: Masa has the ''same reaction'' when he finds out]].
* IllGirl: Hotaru, Enjouji's single mother, had respiratory problems that ultimately killed her.
* IgnoredEnemy: if the enemy isn't worth their attention neither the Yakuza nor the hitmen will give them a second thought. If its Roy, he'll probably continue on a conversation like they're not even there. Although he [[CasualDangerDialog does that anyway]].
* IWantMyBelovedToBeHappy: Given the slightest provocation, Ranmaru will [[HeroicSelfDeprecation start worrying that he's a burden to Enjouji]] or his being with him is interfering with his ability to be happy, and will - somewhat stupidly - consequently try to distance himself or provide Enjouji with the opportunity to break up with him.
* {{Gayngst}}: Yakuza style, and HOW.
* GetAHoldOfYourselfMan: Kai has to slap Ranmaru to get him to pull himself together when he sees Enjyoji has been shot. Considering his BerserkButton and the fact that Kai [[TooDumbToLive left a sword in his vicinity]], this may not have been the best idea.
* GreenEyedMonster: The {{envy}} Kai has towards Enjouji drives a good part of their conflict.
** He also gets terribly jealous and threatened when he thinks Enjouji might be cheating on him.
* LastMinuteHookup: Kai and Masa manage to ''narrowly'' avoid this trope by being technically together for a couple of volumes, but they finally had sex in ''literally'' the last 20 pages. Anyone want to know how many volumes were leading up to that point? Here's a hint: [[spoiler: too goddamn many!]]
* LoveableRogue: Roy. Even Kai can't help but like him eventually - no matter how many times he threatens to move in on Masa. Enjouji also has a fair bit of this in him, particularly around his highschool years, but he never fully fits the trope as well as Roy does, and he outgrows it by the time he and Ranmaru are essentially married. Well... almost.
* MatchMakerQuest: In order to get out of an ''omiai'', Masa stages a confrontation where his intended bride-to-be's straight-laced boyfriend is exposed to her angry father. When the man meekly stands up to Masa to defend his love, Masa ''immediately'' praises him and gives them his full blessing, thus forcing her father to do the same.
* MayDecemberRomance: Masa was - apparently - in his mid to late teens when Kai was born. He spends the majority of Kai's childhood acting like his big brother... which is why he has more than a few issues with how he feels about him later on. Kai, otoh, doesn't see the problem.
* MissingMom: Hotaru's death is in fact a huge plot point. [[spoiler: We also learn that she used to be a geisha, became Takeshi's mistress later, and when she got pregnant with Enjouji [[ScrewThisImOuttaHere she bailed out on the Yakuza environment]] to [[DeliverUsFromEvil protect her baby]].]]
* NamesToknowInAnime: The OAV series has a top-notch voice cast: RyotaroOkiayu (Ranmaru), Creator/KeijiFujiwara (Kei), Creator/RyoHorikawa (Kai), Creator/AkioOhtsuka (Masa), Creator/AkikoHiramatsu (Yuki).
** TheOtherDarrin: In the second OAV series, KazuyaIchijou replaces Creator/KeijiFujiwara as Kei.
* NobleDemon: Jack, ''especially'' around Roy. The reason he initially leaves him is because he doesn't want him to follow in his footsteps to become a killer. Not that that helped any.
* [[AnachronicOrder Non-Linear Story]]: No, you did not miss four books between chapter 1 and chapter 2. Yes, you are going to have to pay ''really'' close attention to things like uniforms, scars and hair-cuts if you want to try to figure out which stories and chapters go where in the overall storyline. No, the chapters that interrupt story arcs haven't been accidentally put in the wrong place. And yes, expect multiple character origins told ''after'' they've been introduced for a couple of volumes. For anyone who gets lost, Kei's long hair and Masa's scar are good temporal landmarks.
* TheOneThatGotAway: variations on this are all through the series. Even Ranmaru and Enjouji's relationship has traces of this. However, the only couple that play this without variation is Jack and Roy - followed by standard NewOldFlame.
* OutOfGenreExperience: you remember that chapter with the angels? Yeah. [[CompletelyMissingThePoint They have pretty wings though]].
* OverTheShoulderCarry: Enjouji carries a struggling Ranmaru this way to bring him inside Rena's hotel in the third OVA.
* ParentalSubstitute: Masa practically raised Kai. [[spoiler: Things get complicated when Kai develops a BodyguardCrush in regards to him, and Masa is ''very'' conflicted due to his own feelings.]]
* ProfessionalKiller: Roy and J.B. [[CaptainObvious The guns and kill-people-for-money thing gives it away]].
* [[spoiler: RapeAsDrama: Kai gets raped by one of Masanori's scorned lovers. Then we have the episode described in FirstNameBasis.]]
* RedHeadedHero: Ranmaru
* RedOniBlueOni: Kei and Ranmaru respectively, especially in the beginning of their relationship, where Ranmaru was continuously cold and reserved while Kei was the one pursuing him with impassioned declarations of love.
* RetiredBadass: a strange example in Ranmaru, who was forced to quit kendo after he [[spoiler: was hit by the car trying to kill Enjouji]]. But that doesn't mean that if you piss him off enough he won't kick your ass into next week.
* RescueRomance: What truly set off Ranmaru and Enjouji's romance was [[spoiler: Ranmaru's DivingSave for Enjouji's sake, which causes him a GameBreakingInjury and keeps him away from kendo competitions.]]
** It should be noted that although they already had a fully established and loving relationship beforehand, [[spoiler: Ranmaru's injury]] completely changed the game and forced their relationship through the make-or-break hurdles.
* SlapSlapKiss: Ranmaru and Kei's relationship has a lot of this, even though it's nearly always followed by AwLookTheyReallyDoLoveEachOther moments. That said, Enjouji can occasionally take it too far and take a swipe at Ranmaru through his insecurities about their relationship that actually hurts him - cue him regretting being a JerkAss and trying to make it up to him.
** Invoked in volume 3 when Ranmaru tells Enjouji that it's okay for them to dump each other if they decide to marry women. Enjouji's response is to smack him across the face.
* SpoiledBrat: Kai, at the beginning. He gets better.
* TallDarkAndSnarky: Enjouji.
* ThisIsGonnaSuck: Roy. It fits in with his CasualDangerDialog compulsion.
* {{Tsundere}}: Ranmaru. Holy ''shit'', Ranmaru. He's - generally - a type B though: nice and kind, but EXPLODES with the force of a bomb when he gets pissed.
** Kai on the other hand is a type A through and through... unfortunately for Masa.
* WhatTheHellHero: Ranmaru slaps Kai and verbally beats him [[spoiler: when he insults Enjouji way too much for his liking.]]
* {{Yakuza}}: ''Very'' involved in the storyline, due to Enjouji being the illegitimate son of a Yakuza boss.
** YakuzaPrincess: Genderflipped with Enjouji's half-brother Kai Sagano. And possibly deconstructed, since being this screwed him up pretty bad.
* {{Yaoi}}: A staple of Yaoi series.
