History BigBrotherInstinct / AnimeAndManga

* In ''Manga/KashimashiGirlMeetsGirl'', [[{{Tsundere}} Tomari's]] [[SchoolgirlLesbians crush]] on her [[GenderBender formerly male]] best friend, Hazumu, comes out of her sisterly instinct to protect her. In the anime that protective side gets a bit less attention, though, and her feelings for Hazumu are presented more as a straightforward crush.

* ''LightNovel/BanishedFromTheHerosParty:'' The person Gideon ever wanted to protect the most was Ruti. This was the main reason he joined the Bahamut Knights, so he could guide her until she was strong enough and could find companions that would support her as TheChosenOne. Part of the reason why he left the party willingly was because he thought his wish had come true and she didn't need him anymore.

** Sesshomaru has a complex, evolving relationship with his brother [[TheHero Inuyasha]] [[spoiler: due to feeling like the [[TheUnfavorite victim]] of ParentalFavoritism]]. Prior to the story's start, it appears Sesshomaru [[BigBrotherBully bullied]] and [[AloofBigBrother ignored]] Inuyasha for not being [[HalfHumanHybrid pure-blooded]] {{Youkai}}, and his first few story arcs revolve around Sesshomaru's efforts to obtain the CoolSword that their father left for Inuyasha -- by [[CainAndAbel murdering Inuyasha]] if necessary. As the story progresses and Sesshomaru's [[CharacterDevelopment character develops]], however, Sesshomaru's motives become more ambiguous, taking on more of a flavour of "IWasJustPassingThrough" and "[[TheOnlyOneAllowedToDefeatYou Nobody kills my brother but me]]". The conflict between them is eventually resolved [[spoiler: when Sesshomaru finally understands what their [[SinkOrSwimMentor father]] was [[ToughLove trying]] to [[CruelToBeKind teach]] him: no matter how strong Tessaiga makes Inuyasha, his half-human nature means he'll always need Sesshomaru's strength and [[BigBrotherMentor support]].]] Although the exact nature of Sesshomaru's protective instincts can be debated in one-or-two cases (notably Jaken [[spoiler: and Kagura]]), his instinct to protect expands throughout the series more-or-less as follows: [[TheIgor Jaken]] (who really doesn't [[BumblingSidekick feel the love]] most of the time), [[MoralityPet Rin]], [[TheOnlyOneAllowedToDefeatYou Inuyasha]], [[IWasJustPassingThrough Kagome]], [[spoiler: [[ImpliedLoveInterest Kagura]], [[ThePromise Kohaku]], until he's eventually openly protecting [[{{Protectorate}} both his group and Inuyasha's group together]].]] Sesshomaru's development is finally [[LampshadeHanging lampshaded]] in the final chapter [[spoiler: when Kagome openly calls him ''onii-san'' (using the kanji for 'brother-in-law') and notices the [[NotSoDifferent disturbed expressions on both brothers' faces are identical]].]]

* Inverted in ''Manga/DrStone'' with Kohaku, who does everything she can to protect her IllGirl older sister, Ruri. This ranges from samll things like bringing her hot springs water to ease her illness to larger things like disrupting the Grand Bout to keep [[{{Jerkass}} Magma]] from marrying Ruri. Ultimately, she chose to ally herself with Senku as he had the medical knowledge to cure Ruri.

* Narumi of ''Manga/KarakuriCircus'', in spades. Masaru begins to mimic him.

* Issei Hyodou from Highschool DxD has a very strong sense of protection towards the younger members of the team, especially the healer Asia whom lacks any kind of offensive power to defend herself. To a lesser extent, he also acts as a "big brother" kind of figure towards Koneko and Gasper, the youngest and smallest (but not defenseless in the slightest) members.

* Nicol from ''LightNovel/MyNextLifeAsAVillainessAllRoutesLeadToDoom'' often protected his little sister Sohpia from all the discrimination she faced for being {{albino|sarefreaks}} when they were younger. [[BigBrotherAttraction It caused her to develop a crush on him in the game's timeline.]] One of the reasons he ends up falling in love with Catarina is due to her being the first person to befriend Sophia.

* In ''Manga/AnatoliaStory'', Yuri initially mistakes a servant boy named Tito as her very young sister, who was lost when Yuri was kidnapped to the past. She quickly befriends Tito, and does ''not'' take it well when the queen tries to use him as a pawn to kill Yuri. When Tito is sentenced to execution for trying to kill Yuri (a member of the royal family by law, as she is disguised as Prince Kail's concubine) while BrainwashedAndCrazy, Yuri runs in, argues down the executioner, and finally convinces Kail himself to call it off. [[spoiler:When Tito is trapped in the queen's castle, after rescuing Yuri, she flies into a massive panic to have him rescued, openly accusing the queen of lying when the queen insists that she has no idea what happened. And when poor Tito shows up FlayedAlive, Yuri promptly declares vengeance on the hired grunt who did it, as well as on the queen for ordering it.]]
** Tito's sisters Hadi, Ryuhi and Shayla all share a Big Sister Instinct for him. When they learn aout his death and (wrongly) are told that it was entirely Yuri's fault, they immediately begin planning how to have Yuri ''killed'' to avenge him. Once Yuri's innocence is proved, the three pledge themselves to Yuri and redirect their loyalties to her.
** Hadi has this for her younger sisters as well as Yuri herself. When she finds out that [[spoiler:Kikkuri was sleeping with both of the twins and knocked one of them up, she coolly makes sure that he intends to look after ''both'' of her sisters]]. And at one point, when [[spoiler:Kail goes insane at the thought of Yuri leaving him and tries to rape her]], Hadi is too frightened to intervene... until Yuri specifically starts shouting her name, begging for help. At that point, Hadi works up the courage to [[spoiler:go into Kail's bedroom and beg him to stop and let Yuri go, even though Kail could easily order her to be harshly punished (if not executed) for it.]]

* In ''Manga/CardcaptorSakura,'' Yukito jokes that, despite Touya's teasing of Sakura, he has a protective instinct when it counts, something he acts out, secretly aware of her MagicalGirl alter life.

* Nicol from ''LightNovel/MyNextLifeAsAVillainessAllRoutesLeadToDoom'' often protected his little sister Sohpia from all the discrimination she faced for being albino when they were younger. [[BigBrotherAttraction It caused her to develop a crush on him in the game's timeline.]] One of the reasons he ends up falling in love with Catarina is due to her being the first person to befriend Sophia.

** The Inner Guardians, [[JerkWithAHeartOfGold even Rei]], will always go out of their way to protect Usagi. Whenever she gets tackled by an enemy, they will immediately come to her defense. Makoto is the most prominent; when she's first introduced in the '90s anime, she [[CurbStompBattle effortlessly beats the crap out of a group of hooligans]] who threatened to mug Usagi.

* ''Anime/SailorMoon'': No matter how much both [[AnnoyingYoungerSibling Shingo]] and [[KidFromTheFuture Chibiusa]] can get on Usagi's nerves, she will [[MamaBear always go out of her way to protect them from harm]]. For Chibiusa, she initially acted like an UngratefulBitch as she didn't appreciate Usagi's help at all nor gave her any sort of respect, though [[CharacterDevelopment she does get better as time goes on]].

* Played straight in ''Anime/MawaruPenguindrum'' with the Takakura siblings. The whole plot is based on Shouma and Kanba trying to save Himari's life. [[spoiler: Even if she is not related to them by blood and just got taken in by the family.]]
** [[spoiler: Kanba deserves special mention since he not only has protective (and romantic) impulses towards Himari, but also sacrificed his position in the Natsume clan and later his life for his ''real'' sister, Masako, not just Himari.]]
** [[spoiler: The aforementioned]] Masako plays it ''super'' straight as well, as she has a little brother named Mario whom she's completely devoted to [[spoiler: and is her reason to take a DealWithTheDevil with BigBad Sanetoshi. (One that ''Kanba'' would take for Himari as well, one must add.)]]

* Guache of ''Manga/TegamiBachi'' has this for his little sister, Sylvette. [[spoiler:Until he looses all of his memories, anyway.]]

* Mai Tokiha from ''Anime/MaiHime'' has a Big Sister Instinct towards her kid brother Takumi.

* Sousuke is this to a male example, [[BrattyHalfPint Shino]], in ''Manga/HakkendenTouhouHakkenIbun''. He is the protective, motherly kind. Examples of his behavior include draping his coat over Shino when he was cold and then letting him fall asleep in his lap, carrying him on his hip like a toddler, and overall just fretting over him. He disciplines Shino and never forgets to tell him to mind his manners and take care of his strength.

* In ''Dorohedoro'', Asu sacrifices his devilhood in order to save Nikaido, whom he consider a sibling, even though they're not related by blood.
* ''{{LightNovel/Durarara}}'''s Shizuo Heiwajima is rather protective of his little brother Kasuka (aka TeenIdol Yuuhei Hanejima). The mere act of namedropping Kasuka is enough to make him suspicious of your intentions, while insulting him or attempting to poke into his personal life results in an instant UnstoppableRage. In the LightNovels & second season of the anime, he eventually goes on to develop another Big Brother Instinct towards a young [[TheRunaway runaway]] [[MafiaPrincess Yakuza Princess, Akane Awakusu]].

* ''Manga/KatekyoHitmanReborn''. Any person willing to injure Kyoko or Tsuna, answers to Ryohei's fists and Tsuna's family.
* ''Manga/KenichiTheMightiestDisciple''

** A much straighter example would be Tsubasa and Souma in ''Manga/KannazukiNoMiko'': the entire conflict between them stems from Tsubasa's desire to protect Souma as effectively as possible, which unfortunately involves pulling him to TheDarkSide and killing his love interest. [[spoiler:Towards the end, however, Tsubasa recognizes that Souma has wishes, too, and helps him to reach ''his'' goals.]] Also, Tsubasa killed their father who beaten up Souma when were very young, which is why they were separated.

** [[AloofBigBrother Byakuya]] only supports Rukia's execution because he's trapped by [[PillarsOfMoralCharacter two conflicting vows]]. The more important vow is to his parents, to always uphold the law. However, he also promised his dying wife that he'd protect her sister as if she were his own sister. Once Ichigo helps Byakuya resolve the conflict, Byakuya quite [[KnightTemplarBigBrother fanatically]] upholds the second vow. Zommari admitting he was going to kill the near-dead Rukia was enough for Byakuya to kill to him, and when As Nodt drops an EmotionBomb attack on him, his worst nightmare is revealed to be Rukia dying.

* ''Manga/MahouSenseiNegima'':
** Ayaka claims to have an overdone big sister instinct which her friends and the viewer apparently [[MistakenForPedophile grossly misunderstand]].
** Asuna has a more genuine version, that occasionally threatens to [[StupidSexyFlanders misunderstand itself]].
** Kaede also feels this way towards both Negi and Kotaro: A LoveChart produced in-universe shows that her romantic feelings for Negi are fairly low, but her ''maternal'' score is off the scale, surpassing the quite motherly Chizuru (10), matching ''Evangeline'' (12) [[note]]May be due to being still in love with Negi's "late" father, wishing ''she'' was the one who bore the man's child(ren), et cetera.[[/note]], and topped ''only'' by Asuna (15). This doesn't always show mostly because of her laid-back personality.

* ''Manga/NaruTaru'': Female-female example: [[spoiler: ActionGirl Shiina has a MysteriousProtector in the form of one of the "Otohime" or "Virgin Princesses". It turns out that said protector is actually her dead older sister, Mishou, who was transformed and reincarnated into an Otohime after her death.]]

* ''Manga/SangatsuNoLion'': Rei starts developing this toward Hina, especially as the latter becomes more prominent in the story. Despite his meek exterior, he consistently acts to protect and console Hina, including getting in the way of boys who try to flirt with her, and seeking her out on her on a school trip (going so far as to take a train to the city she is in after his own affairs are finished) to console her when she's having a hard time.

--> '''Lin''': Don't worry... stay right where you are, I'm coming to get you! You're gonna be fine, I won't let him hurt you.
--> '''Lin''': No Face! If you put even one scratch on that girl, you're in big trouble!
