History TheOnlyOneAllowedToDefeatYou / AnimeAndManga

* In ''Manga/BoysAbyss'', there are a number of people who are quite determined in committing a [[DrivenToSuicide double suicide with Reiji]], among them are two who make it their mission to "sink him further into hell." Reiji's childhood friend Gen attempts to strangle Reiji's mom Yuko, declaring that he would be the one to show him real hell. [[spoiler:He gives up when she says that Reiji was unaffected by Gen [[YouKilledMyFather killing Reiji's dad]], that she birthed him for the sole purpose of dying together, and that the only one to drag him to the very bottom is her]].

* ''Anime/YuGiOh'': Seto Kaiba and Yugi Muto, or rather "the other Yugi". In Season 4 of the anime, Yugi loses to TheDragon. When Kaiba hears this, he throws what can only be described as a "temper tantrum".

** In a strange inversion in ''Manga/{{Naruto}}'', Itachi Uchiha basically says that the only one allowed to defeat him is his younger brother, Sasuke. In Itachi's case [[spoiler:this is all part of a larger plan: he intentionally died, making Sasuke think he won, to make Sasuke strong enough to survive Madara and redeem the clan's honor. That...didn't exactly go as planned.]] Also, Naruto and Sasuke, mutually. [[spoiler:Madara also intends for Sasuke and Naruto to fight as he wants them to settle an old ideological grudge between the Uchiha and Senju clans, with Naruto symbolically representing the Senju. Which ultimate end up happens in the end of the manga after Madara is defeated.]]

** Also, the sound ninja Dosu wants to be the one to fight Sasuke in the Chunin exams, so he tracks down Sasuke's assigned opponent, planning to kill him. Unfortunately, that opponent was Gaara, who murders Dosu in about five seconds.

* ''Manga/KaitouSaintTail'' has the titular PhantomThief and her SympatheticInspectorAntagonist Asuka Jr. form a mutual agreement that he's the only one allowed to catch her, to the point he exclusively gets her [[CallingCard calling cards]] and will [[LetOffByTheDetective deliberately overlook certain things]] to prevent anyone from getting in the way. The initial reason is him needing to [[InferioritySuperiorityComplex satisfy his complex]] over being teased at school in favor of Saint Tail (and his [[GeekPhysiques very poor physical skills]]), but she finds herself [[FoeRomanceSubtext rather drawn]] to his passion about her and doesn't want anyone but him to do the honors. After a certain incident, things get complicated when he starts suspecting that Saint Tail might actually be his classmate and budding LoveInterest Meimi, sharply swerving his motive into [[ControlFreak a refusal to let anyone else touch this before he figures this out himself]], especially after he starts reconsidering whether Saint Tail's actions really warrant her being arrested as a criminal [[ToBeLawfulOrGood just because they're technically not legal]]. [[spoiler:Eventually, they resolve things with him [[ExactWords literally]] catching her in midair, and although Meimi does retire as Saint Tail, Seira's comment in the DistantFinale indicates that their agreement is still ongoing in [[HappilyMarried a more long-term sense]].]]

** [[JokerImmunity Frieza]] develops this attitude towards Goku in ''Anime/DragonBallSuper'', now seeing him as a WorthyOpponent rather than [[FantasticRacism (just) a filthy monkey]] like he did in the Namek saga. In ''Anime/DragonBallSuperBroly'', when Peragus and Broly attempt to get revenge on Vegeta [[SinsOfOurFathers over his father's treatment of them]], Frieza allows it on the condition that Goku is left alive.

->'''Kaiba''': YUGI LOST!? Yugi gave his Duel Monsters championship crown to some nobody!? No one deserves that title but me!//
'''Yami Yugi''': Hold on...//

** Ichigo and Zaraki Kenpachi, although it's one-sided on Kenpachi's side since Ichigo wants nothing to do with that fight. Zaraki tends to want to go to the Human World whenever Ichigo's involved with anything there so he can fight him again. Though it's not so much that he wants to kill him, he just wants a sparring partner who can actually challenge him.

* In ''Series/{{Kikaider}}'', Hakaider/Saburo's main objective is to destroy the titular android. He resolves the existential crisis of that being his only reason to exist by destroying any other MonsterOfTheWeek that comes close to killing Kikaider while pushing him to his limits so he can get his money's worth out of his goal when the time comes.

* ''Franchise/FullmetalAlchemist'':
** In ''Manga/FullmetalAlchemist'', Colonel Mustang invokes this trope after finally tracking down Envy, [[spoiler:Hughes's killer. The other characters leave him to it, but soon realize that [[HeWhoFightsMonsters he won't be coming back]] [[MoralEventHorizon from that path]], and come back to stop him]].

* ''Franchise/LupinIII'':

* Suzuka and Gene Starwind in ''Manga/OutlawStar'' (The HeelFaceTurn variant again, and probably a {{Homage}} to ''Franchise/LupinIII'').

* Ichigo and Zaraki Kenpachi in ''Manga/{{Bleach}}''. Although, Ichigo wants nothing to do with that fight. Zaraki tends to want to go to the Human World whenever Ichigo's involved with anything there so he can fight him again. Though it's not so much that he wants to kill him, he just wants a sparring partner who can actually challenge him.
** Later, Ichigo with Grimmjow, to the point where there is not one rematch, but ''two''. Also, Grimmjow gets inordinately pissed when he finds out other rival Ulquiorra's been going after "his prey."

* In ''LightNovel/{{Baccano}}'', while Ladd Russo and Lua Klein are not rivals, Ladd does promise to be the one to kill her and will let no one else do it.
** He gives a similar response to [[TalkativeLoon Graham Spectre]], stating, "I like brazen, impudent guys that only I can kill." Graham may as well have [[HoYay taken it for a love confession]].

* ''LightNovel/ACertainMagicalIndex'' and ''Manga/ACertainScientificRailgun'':

* A really weird inverted example in ''LightNovel/{{Corsair}}'', where [[ProfessionalKiller assassin-trained]] [[TheStrategist Kanare]] is only happy once he has [[SuspiciouslySpecificDenial repeated assurances]] from his lover MasterSwordsman [[TheStoic Ayace]] that if he goes on a killing spree Ayace will kill him. [[SarcasmMode Uh-huh.]] [[LoveMakesYouDumb Suuuurrre.]]

* In ''LightNovel/TheDevilIsAPartTimer'', this is the default attitude of Emi Yusa, hero of Ente Isla, towards her arch-nemesis Satan, or Maou Sadao as he goes by on Earth. Unfortunately, because neither one of them can use their magic for very long and Maou appears to be a regular human due to his lack of magic, to Earthlings she just comes off as a ClingyJealousGirl and StalkerWithACrush who hasn't gotten over her breakup with Maou.

* In ''LightNovel/FateZero'', after Saber and Lancer's duel was interrupted by the other Servants getting in on the action, Lancer developed a major case of this towards Saber, [[IWasJustPassingThrough even going blatantly out of his way to save her on numerous occasions.]] Given that, in said duel [[spoiler: she received an incurable wound that will only go away if she defeats him]], the feeling is probably mutual.

* In ''LightNovel/HaruhiSuzumiya'', [[spoiler: Ryoko Asakura]] invokes this when [[spoiler: she protects Kyon from Kuyo Suou, calling him "her prey", and drives the point home by holding a knife at his throat while fighting]].

* In ''LightNovel/SoICantPlayH'', Ilia gets pissed if anyone interferes with her rivalry with Lisara, as she feels a victory over her would be meaningless unless she defeats her herself.

* ''LightNovel/SwordArtOnlineAlternativeGunGaleOnline'': A justified example. In the second Squad Jam tournament, Pito has decided that if she dies in the game, she'll kill herself in real life. However, earlier she promised her friend LLENN that if LLENN managed to defeat her in a duel, they could meet up in real life. So LLENN has to be the one to kill Pito to save her life.

* ''Manga/KaitouSaintTail'' has the titular PhantomThief and her SympatheticInspectorAntagonist Asuka Jr. form a mutual agreement that he's the only one allowed to catch her, to the point he exclusively gets her [[CallingCard calling cards]] and will [[LetOffByTheDetective deliberately overlook certain things]] to prevent anyone from getting in the way. The initial reason is him needing to satisfy his complex over being teased at school in favor of Saint Tail (and his [[GeekPhysiques very poor physical skills]]), but she finds herself [[FoeRomanceSubtext rather drawn]] to his passion about her and doesn't want anyone but him to do the honors. After a certain incident, things get complicated when he starts suspecting that Saint Tail might actually be his classmate and budding LoveInterest Meimi, sharply swerving his motive into [[ControlFreak a refusal to let anyone else touch this before he figures this out himself]], especially after he starts reconsidering whether Saint Tail's actions really warrant her being arrested as a criminal [[ToBeLawfulOrGood just because they're technically not legal]]. [[spoiler:Eventually, they resolve things with him [[ExactWords literally]] catching her in midair, and although Meimi does retire as Saint Tail, Seira's comment in the DistantFinale indicates that their agreement is still ongoing in [[HappilyMarried a more long-term sense]].]]
