* Mikan Sakura from ''GakuenAlice''. She's eternally optimistic, and happy. She's the EXACT DEFINITION of the Pollyanna. Even after [[spoiler: Mikan discovers her alices]] and all the horrible stuff that happens to her, she always cheers everyone up. Even [[spoiler: Natsume and Luka love her, eventually. And Natsume Truly and deeply loves Mikan. But really, who CAN'T love Mikan?]]
* [[Anime/ExcelSaga Excel Excel]], the ultimate oblivious GenkiGirl, who will always believe that she is Il Palazzo's favorite minion no matter how violently he rebuffs he, until [[spoiler: Il Palazzo shoots her at the end of episode 23. Although he has shot her before, including with antimateriel weapons, during this episode the ToonPhysics are turned off]].
* Tohru Honda from ''FruitsBasket''. In the anime, the other characters [[ExtremeDoormat use her as a doormat]], but she remains eternally perky and eventually wins them over. In the ''manga'', on the other hand, while she acts the same, she's also shown as doing some serious repression.
* Kafuka Fuura (pictured on the main page) is an extreme form of this trope, in order to act as an antithesis to the namesake and other protagonist of ''Manga/SayonaraZetsubouSensei''. She has had an amazingly tragic childhood and goes to a school filled with social misfits, yet she is either too oblivious to notice or in very, very heavy denial. She's also easily the scariest example on this page. Although she never breaks her [[StepfordSmiler cheerful facade]], the series drops many hints that she is [[CuteAndPsycho quite disturbed and a stone's throw away from killing everyone around her]]. [[spoiler:She is DeadAllAlong. [[FridgeHorror Now review the series and her actions again.]]]] For example: While her close friend and classmate turns into a giant after finding an ancient weapon during a festival and then begins to battle huge robots with toilet profanities on their chest ([[ArsonMurderAndJaywalking all while wearing underwear with a traditional Japanese dress]]), Kafuka can only remark about how well the Kanji on their chest are carved. Or how well Chiri is doing fighting the aliens. Or how professional dog rapist Mayo Mitama is sticking a branch up her neighbor's dog's butt.
** Maria Taro Sekiutsu, a grindingly poor illegal immigrant who frequently expresses rose-tinted views of Japanese life, is an only somewhat less extreme example.
* In ''Manga/HayateTheCombatButler'', we have the titular Hayate. He has gone through some seriously heartwrenching moments as a child including: being sold off by his parents for frivilous reasons, being ostracized in school for having such parents and people assuming he's the same way, leaving his first and best friend in a fight caused and not being able to apologize because they were seperated, and having to work various degrading odd jobs to support his parents' gambling habit. Perhaps because of this, he strives to be the best butler he can be and flat-out refuses to burden people with his problems, so he smiles; whenever someone asks him about his past, he always answers cheerfully and never complains.
** Hayate ''has'' actually gotten mad at and expressed hatred for his parents a few times.
* Sora, protagonist of ''KaleidoStar'', has a will of steel, considering the hoops she's had to jump through to get to the top (both figuratively and literally).
** Sora is actually a massive subversion. Despite being super sunny and plucky, she ''does'' have several breakdowns ([[spoiler: to the point of temporarily leaving the Stage in the second season]]), and later has to settle for a ''somewhat'' less rose-tinted view of the world. Considering she's a massive deconstruction of PuritySue, it makes sense.
* Milfeulle from ''Anime/GalaxyAngel'' is almost impossible to make depressed or sad for very long, even when starving to death, being completely broke, having people actively trying to kill her, being ''dead''...
* Kasumi Tendo from ''Manga/RanmaOneHalf''. Nothing catastrophic happens to ''her'', but she does seem to find herself ''witnessing'' catastrophe on a regular basis. Unless you count being possessed by a [[HarmlessVillain demon]] as catastrophic...
** Nodoka Saotome is [[ParentalAbandonment far]] [[PerpetualPoverty more]] [[TheFettered aware]] [[{{Seppuku}} of]] [[FeedTheMole her situation]], but refuses to let it get to her, making her optimism seem heroic next to the passivity of Kasumi (who lives in a big house, surrounded by family, not a care in the world.) At least, until she starts [[TearJerker crying in her sleep]]... and reenacting a {{Seppuku}} ritual.
* ''Manga/{{Bleach}}'': Orihime Inoue is ultimately a subversion. She ''seems'' to be this in the first arcs, but she's later revealed to be a StepfordSmiler who hides her massive self-esteem and lonely issues behind her smile... and once she's taken out of her more-or-less safe Karakura environment, [[BrokenMessiah she's subjected to]] a BreakTheCutie process. [[spoiler: She arguably plays this straighter when she's back home, but it can also be seen as a coping mechanism: she ''does'' state that she's had a rough life, but [[AngstWhatAngst is trying not to dwell on it anymore]].]]
* Rico from ''GunslingerGirl'' fits this trope, being overly happy with her new life as a cyborg-assassin, although it can likely be attributed to her aggressive [[{{Brainwashed}} mental conditioning]].
** It's arguable that her unfailingly cheerful attitude comes mostly from her joy at being able to walk, [[IllGirl something she'd been unable to do before her new life started]]. There is at least one moment in the manga that shows rather plainly that losing her mobility is her greatest fear.
* If Nunnally Lamperouge of ''Anime/CodeGeass'' isn't this trope, I don't know what is.
** Subverted in R2. [[spoiler: Boy, does she take it hard upon learning what her brother did to create a better world for her...]]
* Subverted in ''SonicX'' by Cosmo, whose entire family was wiped out by the Metarex right in front of her and who has frequent feelings of self doubt, Survivor's Guilt, shame ''for her own hatred of the enemy'' and unworthiness.
* Brook from ''OnePiece'' is an interesting male example of this trope. One of the characters almost Lampshades this by asking why he's so cheerful even though his life has been awful. It's heavily implied that Brook has gone insane from all of his trouble, though.
** Really, most of the Strawhat Pirates fit this. Luffy fit this partly before the timeskip, what with witnessing [[spoiler: Sabo dying, while trying to become a pirate, and still not giving up on his dream of being the Pirate King.]] After the timeskip he fits this even more, since [[spoiler: he saw his brother, Ace, getting killed right in front of him, and he still managed to push past it and have a positive outlook on life and keeps following his dream.]].
* Lacus Clyne, from ''GundamSEED'' is a borderline example. She manages to maintain her childish idealism in spite of everything that happens, including her father losing his office to a genocidal maniac and then being murdered by him, along with most of his supporters and nearly Lacus herself, the nuking of several colonies and just generally living through a Gundam show. She ''did'' cry when she told Kira about her dad [[spoiler: and was ''very'' upset when her BodyDouble Meer [[TakingTheBullet took a fatal shot]] for her]], but other than that, she rarely breaks down.
* [[CandyCandy Candace White Andree aka Candy]], of course.
* Nadja from ''AshitaNoNadja''. [[spoiler: Until the second part of the series, that is. [[PluckyGirl She still manages to bounce back.]]]]
* Keiichi Segawa from the ''{{X1999}}'' manga. Lost his father in early childhood, and then his mother is killed in one of the earthquakes caused by the Dragons of Earth, yet he remains optimistic and kind until finally being phased out of the series.
* Usagi of ''Franchise/SailorMoon'' isn't as much of a Pollyanna as fanfic writers would have you believe (where Usagi is a perky saint and can never be pried from her hold on a "good in everyone" mentality), but she does have an overwhelming belief in the power of love in the anime. The [[Manga/SailorMoon manga]] and [[Series/PrettyGuardianSailorMoon live-action]] are much darker, though.
* Elmer C. Albatross from ''LightNovel/{{Baccano}}''. The woobie factor is subverted in that most people find his constantly chipper, love-everyone attitude to be inappropriate and incredibly insensitive: "C'mon, let's laugh together!" is ''not'' what a teenage girl wants to hear just after [[spoiler:nearly being killed by her fiance's murderer]]. Pretty much the only person that doesn't find him creepy is the equally creepy Huey Laforet.
** We eventually learn that his Pollyanna nature is actually a front. Not that he feels sad about anything. Just the opposite: ''he's a sociopath.'' He doesn't care about anyone, but he wants everyone to smile just ''because.''
* Princess Amelia of ''{{Slayers}}'' both plays this trope straight and subverts it at the same time. While she is truly the optimistic type who finds good in ill situations, a part of it derives from her [[RoyallyScrewedUp incredibly bloody and crappy family history]] that drives her right into StepfordSmiler territory at times.
* Nana from ''Manga/ElfenLied'' is ''clearly'' [[BreakTheCutie broken]] by the time we meet her and continues to have horrifyingly terrible things happen to and around her for the entire story. She nonetheless somehow clings to a generally positive outlook that everything will be okay, especially as long as she can be with papa again.[[spoiler: She doesn't. He explodes]]
** [[spoiler: He does survive in the manga, though.]]
* Nao Kanzaki from ''LiarGame''. Altough when things go real bad, she panics to the point of tears.
* Subaru during ''[[AudioAdaptation StrikerS Sound Stage X]]'' of the ''MagicalGirlLyricalNanoha'' franchise. Turns out that the EmergencyServices she joined [[ItNeverGetsAnyEasier isn't all sunshine and roses]], and she not only gets front row seats to a PsychicAssistedSuicide, but she also loses the new friend she had rescued after she slips into a coma that may last a thousand years. Still, she never loses her smile and [[GenkiGirl energetic personality]]. After all "Even though you're so sad, you've still got to eat. And if you get sleepy, you got to sleep. And if you have to do something, you do it... When you're doing all that, all your painful memories start fading away..."
* It's very, very difficult to upset either [[DGrayMan Allen Walker or Lenalee Lee]] permanently. Allen in particular has been put through staggering amounts of crap by a universe that clearly has it in for him, but is nevertheless an AllLovingHero and a WideEyedIdealist who wants to save ''everyone''.
** Lenalee is actually a StepfordSmiler, due to [[spoiler: the ''brutal'' TrainingFromHell she went through.]]
* Another male example would be Yamamoto of ''Manga/KatekyoHitmanReborn'', who very rarely loses his smile (and when he does, [[BewareTheNiceOnes RUN]]) even in the worst of circumstances. Although he isn't unusually optimistic, he remains constantly cheerful despite the sometimes nightmarish situations he's encountered as guardian to a budding mafia boss. Perhaps this is because he [[{{failedaspotcheck}} thinks that his entire life in the mafia has all been one big elaborate role-playing game.]]
** Though he has currently (as of the Time Travel Arc) been told the truth, and actually knows more about certain backstory elements than any of the main characters, not to mention the readers
* Shu from ''NowAndThenHereAndThere'' is as straight an example of this trope as you could ask for.
* Negi of ''MahouSenseiNegima'' ''starts'' as one of these, but when he begins training under [[NobleDemon Evangeline]], [[CombatPragmatist she]] specifically makes it a point to knock that out of him, because the world is not that nice, and he needs to realize that. As it turns out, she wasn't entirely wrong.
* No matter how many times Shibuya Yuuri from ''LightNovel/KyoKaraMaoh'' is betrayed, he is always willing to give that person a second chance. When a girl is jailed for posing as his daughter and trying to assassinate him, he smuggles her out and adopts her.
* ''Manga/InuYasha'': Within the first chapter of her introduction, 7-8 year old [[MoralityPet Rin]] is revealed to be an orphan who watched her entire family be slaughtered by bandits in front of her eyes (a trauma that left her mute and continuing to suffer nightmares), who is scrounging a living on the outskirts of her home village, being beaten by the villagers for stealing fish to survive... and then she's [[FirstLawOfResurrection murdered]] by [[{{Youkai}} wolf-demons]]. After she joins Sesshoumaru's group, she continues to be a target for kidnapping and attempted murder. Despite everything that's happened to her, she remains a constantly cheerful, upbeat person to the end.
* The eponymous character of ''Manga/HelenESP'', who doesn't let being rendered blind, deaf, and mute and her parents dying get her down. Though, this is after some backstory CharacterDevelopment from being a very bitter girl.
* Jean from ''NadiaTheSecretOfBlueWater'' is a shoe in for a inventor's competition which he ditches to save Nadia, and not only does his plane crash but he is perpertually on the run and in constant danger. And yet, through it all, he is cheerful and even enthusiastic about the technology from both sides in general. (Only exceptions is when he and Nadia exploring Gargoyle's base, and even reacting in horror to two deaths—one of an escaped fugitive, and another, a crew member. This latter incident causes for a BreakTheCutie moment that turns into a HeroicBSOD when he learns his father is dead. [[CrowningMomentOfHeartwarming Nadia cheers him up by reminding him of his promise to her and encouraging him to build a gyrocopter.]])
** [[DefrostingIceQueen It could even be noted, too, that Nadia herself is transformed by his caring, compassionate nature.]]
* Takeru from Manga/SnowWhiteAndSevenDwarfs. While he does have his moments when he's upset, he's generally upbeat and cheerful despite being in a CrapsackWorld, making it a point to try and remain positive no matter what happens.
