By the end of Cowboy Bebop, Ed and Ein have abandoned the ship to search for Ed's neglectful father, Jet's ship is wrecked and his leg injured, while Faye discovers that her family history is unsalvageable, and all of her friends old are dying. Meanwhile, Spike is planning a suicidal assault on Vicious' Red Dragon Syndicate. Spike discovers that the woman who abandoned him 3 years prior and sent him down his self-destructive, fatalistic path was still alive. He meets her in the cemetery where they had planned to run away together, and learns that she had abandoned him to avoid getting them both killed by Vicious, who returned from the Titan war furious at being betrayed by both his best friend and his lover. They reignite their plans to run away from the Red Dragon Syndicate, which they were both high-ranking assassins for. This plan lasts about the span of half an episode, 10 minutes, of the series' 570, before she's tragically shot in the back by some mook on a fire escape. Before leaving he tells his friends perhaps the most he's ever told them about himself, and abandons the Bebop for the last time. In thin metaphors he explains to Jet and Faye that, since the disappearance of Julia and the loss of his eye, he's seen his past replayed in the fake eye and reality repeating in his real eye, leaving him uncertain if he is alive or in a bad dream. He tells them that the only way he can validate his love for Julia, and free himself from his dream-like state, is to find out if he was really alive by dying. The only way the ending could have been more depressing, at least on the surface, is if Punch, Judy, the two remaining old men that dug the gates and Rocco's sister were all somehow killed in the climactic battle. There is a happy ending, however, for all of the characters. Ed finds a purpose, his friends, and the potential for finding her father again. Jet resolved some major loose ends in his life and has a real shot at peace. Faye lost her past, but is a strong woman, and has a future ahead of her. Spike, in finding death, discovered that his life was not just a dream, and his love for Julia was genuine.
Blue Gender takes place in a very dark, gritty, cynical, cold world after theBlue have taken over the Earth. Human life has lost all of its value and the only thing that matters is defeating the Blue, regardless of any and all cost. Idealistic protagonist Yuji and his Defrosting Ice Queen love interest Marlene have lost everything to the Blue, and almost every friend they make through the course of the series dies, usually in a rather horrifying way. Yuji is even driven to the point of madness in one episode. In the end, however, Yuji's idealism rubs off on Marlene, she pulls him back from the edge, humanity survives (we've been knocked back almost to the stone age, but at least we're not going extinct) and Yuji and Marlene finally get to have a happy life together.
The religious angle is arguable; the novel makes a point of that even though religion is well-meaning by nature, it's unable to help people suffering from serious depression. Misaki's uncle and aunt are deeply religious, and want to help their niece to the best of their abilities, yet are still quite blind to the fact that she's close to being suicidal.
Surprisingly, Code Geass ends like this. It takes a lot of planning, however, including the protagonist taking over the entire world as an evil dictator, and his best friend, at the protagonist's insistence, publicly assassinating him. OK, the hero's ending wasn't so happy, but he did achieve his goal of breaking the cycle of international conflict and creating a gentler world for his little sister.
One wonders if Nunnally would consider it a happy ending, though...
Indeed, given her reaction to it all it could very well be interpreted as more of a Bittersweet Ending.
A personal one for Jeremiah Gottwald. The person who he greatly admires is killed on his duty, and his status gets stripped from him because of his failure to capture Zero. He almost dies when trying to get his revenge and his life is used for research. He returns powered up from that research to get his revenge again, but this time he's sent to the depths of the ocean. When he learns that Zero is actually the son of Marianne, whom he greatly admires, he understand Zero's reasons, swears loyalty until Lelouch's death, and lives happily in the aftermath.
In Code Geass: Nightmare of Nunnally, Nunnally manages to save the world from Charles' Assimilation Plot, regains her sight and her mobility, and is able to properly say goodbye to Lelouch before he leaves to become Demon King. Despite the difficult work for restoring peace that lies ahead, Nunnally believes that humanity can bring it about.
Macross Frontier did this as well, after at least five episodes of utter bleakness, kicked off with a Big Damn Heroes moment from SMS, and culminating in a nuclear disarming-of-giant-robot-via-shanking, one multi-kilometer high robot gut-punching another multi-kilometer robot, songs Saving The Day, the Vajra turning good and protecting the Frontier fleet, The Rival teaming up to take down the Big Bad, Alto blowing off the Big Bad's head with Michel's sniper rifle, and everybody being happy happy love love on the Vajra home planet. Oh, and Everybody Lives except Michel. Even the character with the terminal disease. The 2nd movie however, ends with a Bittersweet Ending.
Magical Girl Lyrical Nanoha does this every season. Mood Whiplash is used like a weapon by the writer, turning some of the darkest, most painful depths of despair into happy endings where almost everyone gets a Good End. A's has the darkest ending of the entire series, and it's merely a Bittersweet Ending. The sole exceptions to this are Precia Testarossa in Season 1 and the overarching conspiracy within the TSAB and Jail Scaglietti in StrikerS. Arguably, this prevents any case of Karma Houdini that even the series' heavily grounded idealism couldn't excuse.
The ending to the Rurouni Kenshin manga has Kenshin Happily Married to his second wife Kaoru, and having given away his sword. Kaoru has restored her school to a lot of students and is the happy mother of Kenshin's kid Kenji at the same time, Sanosuke is off to see the world, Yahiko is a famous swordsman, and Megumi goes to Aizu to practice medicine while trying to find the rest of her family. The TV anime ends with a Gecko Ending but still a very positive outcome. The OVA on the other hand is a Downer Ending that wasn't even close to the manga's ending: Kenshin and Karou are deathly ill, he ends up amnesiac in China and along with Sano he has to go through Hell and back to return to Japan, Kaoru is barely hanging on thanks to her desire to see Kenshin one last time, and in the end Kenshin goes back home and dies in her arms, only to have her dying soon afterwards. The only bits of hope are these: Yahiko successfully dissuades Kenji from taking up the Hiten-Mitsurugi fighting style and helps him to stop hating his Disappeared Dad. Soon after, Kenji takes off with his girlfriend (who looks like a younger Kaoru) to build a new life away from Tokyo.
Played straight in regards to Fuji, the Gentle Giant of the Juppongatana. Already an Anti-Villain who was mentored by a Smug Snake after being almost killed by scared guards, he's regarded as pretty much a living weapon and not even a human, until Hiko Seijuuro sees through him and treats him like a person in their duel. Later, he cuts a deal with the Meiji government and becomes a rural guard in Hokkaido, finally having a peaceful life with friends and co-workers that see him as the good guy he is.
Planetes waffles a bit at the beginning, then nosedives into increasingly cynical or even pessimistic territory... but idealism wins in the end, even with the terrorist characters.
Terrorist subplot was greatly overblown in anime, while the crazy salarimen antics were invented out of the whole cloth, but the manga had its share of troubles and hardships. They're mostly on the Fee's part, as most Clare's problems in the anime happened to her in the manga, though Tanabe didn't escape them too.
While not in full use in the series itself (since, y'know, it hasn't ended yet), Mahou Sensei Negima! plays this in regards to Setsuna, a warrior who having lived her life as an outcasthalf-demon, found happiness in protecting Konoka as a simple bodyguard. In their childhood she failed to protect Konoka, causing her to distance herself from the girl in order to train harder and become colder, feeling that emotion was the weakness that caused her to fail. This distant relationship with Konoka was later resolved, and she become calmer and more cheerful, like her younger self. Later, in a pseudo Secret Test of Character, Evangeline forced her to choose between which was more important: becoming a cold-hearted swordsman without limits to better serve Konoka, or remain as she was in her current happy state, while losing her sword to Evangeline in doing so. With the two ideas conflicting with one another, only being able to lose with available options, she chose to have both. Whether she'd actually be able to do this or have a happy ending at all has been a running plot-line for her ever since.
Mars has this in escalating spades, culminating in a white-knuckled, tear-jerking Grand Finale when Rei gets stabbed in the gut by recurring Depraved Bisexual Masao Kirishima, while he's on his way to the party celebrating his marriage to the girlfriend he's been through hell and resolved all of their respective Backstory trauma with. They still get to live happily ever after.
Saji Crossroad from Gundam00. The poor guy had everyone he loved taken from him, spent most of a season finding out just how much he lost, wound up as the hostage of the very people he thought were responsible for it, then nearly died at the hands of theperson (and alsohisloverival) he was trying to return to multiple times. And only barely succeeds in getting said person ( Louise) back to sanity. If anyone in recent fiction earned the right to a happy ending, it's him.
The Kyoto Animation adaptation of CLANNAD had Tomoya die, so that he would be reborn as the Garbage Doll in the Illusionary World. Only then could he be given the opportunity to save Nagisa and by extension, Ushio, when the Girl in the Illusionary World/Ushio sent him back in time, prepared to prevent Nagisa's Death by Childbirth.
The Excel♥Saga anime ends on a very happy note. Excel and Il Palazzo escape the exploding ACROSS base by going down the trap door together, the closest thing to mutual affectionate gesture the two have ever had; Watanabe escapes with Hyatt and the rest of Daitenzin, technically beating ACROSS; and Pedro and Sandora defeat Tha Man and rescue Pedro's Sexy Wife. While it could be interpreted that everyone died in the explosion, the scenes shown during the credits show everyone alive and back to their old lives. Everyone is also alive during the next episode, but the canocity of that is dubious.
Mirai Nikki: Yuno's "Yukiteru Diary" predicts that she and Yukiteru will "become one" on July 28, 20XX and get a HAPPY END. Said ending is threatened on multiple occasions; it goes away when Yukiteru discovers the corpses in the sealed-off room in her house (but comes back after the 6th is defeated), and after the defeat of the 10th (during which Yuno tries to snatch Yukiteru away from his friends), Yukiteru warns that if she wants to win his heart and earn her happy ending, she will need to accept his friends.
It seems she recently got this HAPPY END, though the story hasn't ended yet.
Looks like it's headed this way, though, what with all the diary holders preventing their screwed up lives in the new universe.
It required Yuki to travel back in time to create a new world and defeat Yuno and MurMur to get a happy ending where everyone is alive and rather well, including himself and Yuno, they are then invited by Deus to become gods of the new world and got their chance to see the stars together.
Liar Game seems to be heading this way - yes, most of the eponymous game's players are deceitful and desperate to come out of the game with a profit, but Nao's attempts to persuade them to unite against the LGT and share their money to keep everyone out of debt seem to be having some effect. Of course, it's too early to know to what extent this will work...
The ending of the Maya subplot in Azumanga Daioh. Suffer the animosity of a thousand cats so you can actually own one, happy ending definitely earned.
Princess Tutu ends with the heroine not getting the guy she spent the entire series trying to help and forced to give up the ability to be a girl forever on top of it, but in the end it's still shown that she's happy and with someone that cares for her. In fact, all of the characters are put through a lot of extreme emotional torture throughout the series (to the point that three of them threaten suicide at one point), but they all end up with a happy ending, although for some it's more bittersweet than for others.
Used in the Grand Finale of the Eureka Seven anime. When Renton is huddled in a fetal position, believing Eureka is dead and that current events are going to cause The End of the World as We Know It, and begging Holland to beat on him like he used to. Holland simply tells him to stand up and get ready to go to where Eureka is. His way of saying "Don't expect us grown-ups to fix shit for you." If that was too cryptic, Holland pretty much says it when Renton is about to pilot the new Nirvash into battle, telling him to "Go steal away the woman you fell for! You're a man, aren't you?"
The manga version of Chrono Crusade fits squarely within this trope. After the end, it's shown that almost all of the characters go on to live happy, normal lives, and those that don't are working towards their own chances to earn a happy ending. Even several of the villains get an Alas, Poor Villain moment at their deaths.
Kinda-sorta played straight in Neon Genesis Evangelion, but in such a twisted and subversive way that few will realize it, at least on first viewing. Rebuild of Evangelion seems to be playing it even straighter, though only time shall tell.
To expand a little, humanity has been reduced to a single mass of consciousness, but thanks to Shinji, everyone has the potential to become an individual human again. It's not really a happy ending, given that people can only come back if they're strong willed enough, and if they do come back, it's to an almost deserted world, but it's certainly happier than the Kill 'em All ending it first appears to be.
Among other things, Elie of Rave Master had to fake her death, go into a deep sleep for fifty years, and never really see her friends again in order to stop the ultimate evil.
And then, the Grand Finale has everyone else earn their ending when they believe Haru makes a Heroic Sacrifice to finally destroy Endless. Everyone (especially poor Elie) has to endure that knowledge for a whole year (with varying degrees of response). The ending's finally earned when they return to the site of the battle exactly one year later...and he reappears, having been sent one year into the future by Star Memory to save his life.
In 20th Century Boys, the Big Bad Friend actually manages to realise his plans of dominating the world, and manages to completely screw over the protagonist's attempts to stop him. Twice. This includes him releasing a virus that kills a ridiculous percentage of the world's population, among other things. It's only after 20 years (in story) since the series started that the heroes finally manage to overthrow him and save the world.
All the happy season finales of Sailor Moon are earned through blood, sweat, and an ocean-full of tears.
Now and Then, Here and There ends on a bittersweet note, with Lalaru fading so as to bring water back to the world and a very good portion of characters we liked killed off, but given the utterly depressing way the series plays out up until that point, it's clear what sweetness there was to the ending had to be fought for tooth and nail.
Fullmetal Alchemist Ed and Al. I mean, come on, after everything that happens to them. Let's remember, shall we? Their father, Hohenheim, leaves them and their mother, Trisha, without telling them why (Trisha knew, though). They lose their mother at the tender age of 4-5. The parents of their best friend, Winry, were murdered. They try to bring their mother back from the dead just so they can feel the love they so desperately miss. They fail and come back screwed up. They than fail to save a little girl, Nina, from her insane father, Shou Tucker. Later they lose a close ally, Hughes, and later discover it was partly their fault he was murdered. They than have to deal with the fact they left a family broken. Next, they discover said best friend's parents murderer, Scar, and have to try and stop her from trying to exact revenge. Then their close friend, Ling, is possessed by a homonculus. Then they have to take on Father, the original homunculus on a quest for godhood, who blinds Roy and steals the souls of everyone else in the country (dooming all those people to A Fate Worse Than Death) to fulfill that quest. Next, Al sacrifices himself so Ed could survive and win. Then Ed sacrifices his ability to use Alchemy to bring back Al. In short: wow, they really did deserve that happy family photo at the end of Chapter 108.
Not to mention everyone gets their soul back; Father is defeated; Al is saved (body included); Ling befriends Greed, regains control of his body, and becomes emperor of his home country; and Ed hooks up with Winry and has two kids. It's also implied that Al hooks up with May, and Hohenheim can finally die in peace by Trisha's grave.
The death of Hughes wasn't their fault at all, despite what the boys may think. He was investigating the leader of his own military as a traitor. Even in Real Life, this could easily be seen as leading to treason; it didn't help that the people he was investigating were alchemical constructs with superpowers. It was only a matter of time, really.
Maison Ikkoku features the Ronin Yusaku Godai's near never-ending attempt to graduate college, get a good job, and marry the woman he worships. In his path are middling grades, general mediocrity, financial woes, Jerkass roommates, a "girlfriend" he's too cowardly to dump honorably, a teen girl who is obsessed with him, and another suitor to the girl of his dreams, who is extraordinarily wealthy and perfect. Does he earn it? Hell yes.
Zorua and Zoroark from Pokémon: Zoroark: Master of Illusions are kidnapped and taken from their home and then separated by the movie's sadistic Big Bad, Grings Kodai. Zorua does manage to escape but is left searching desperately for his mother, who Kodai tricks into believing he still has Zorua and forces to rampage through the city. Both get electrocuted (and NOT the harmless kind normal to Pokemon), beaten, tortured, and put through absolute heck by Kodai. Then when it looks like they're finally about to reunite, Kodai KILLS Zoroark right in front of Zorua! Finally, Celebi restores Zoroark to life to repay Zorua for working his tail off to protect it and is finally reunited with Zorua, they get to witness Kodai get one of the most satisfying Humiliation Congas in history, and are finally returned home. When you see them nuzzling each other as they arrive back home, you know they deserve it.
Black and White from Tekkonkinkreet accomplish this, using their implied Psychic Link to stop Black's descent into madness and finally escaping the city to live by the sea. After all the beatings they took and psychological trauma they suffered, it definitely felt like they earned it.
Puella Magi Madoka Magica follows this trope to a T. The series itself is full of angst and tragedy, yet the main character manages to make things somewhat right by forcing reality to rewrite itself by preventing Magical Girls from becoming witches with her own hands. As a result, Mami and Kyouko are brought back to life because they never died fighting witches. It came at the cost of her own existence, though she doesn't seem to care about that. It is implied that Madoka takes fallen Magical Girls to some kind of afterlife, which is a much better fate than becoming a witch.
The PSP game makes a more conventionally happy ending possible, but it's one among over a dozen bad endings, only accessible after at least four previous completions of the game (in order to even unlock Homura).
And in Puella Magi Madoka Magica The Movie: Rebellion this is actually deconstructed. Homura earns her own happy ending and creates a world where Madoka and Sayaka are still alive...by stealing a portion of Madoka's power to become the devil itself. It's heavily implied that this state of affairs won't last, and Homura explicitly states that her and Madoka will eventually become enemies.
GUN×SWORD is often praised for having a satisfying ending, but the characters really have to work (or, in some cases, wait) for it. Van gets his revenge, but he is left walking the earth alone again afterwards. Wendy loses her last family member, and she has to wait for at least a few years for Van to wander back into her life. Sadly, not all the good guys get such a happy ending.
Gosick: In many stories the crowning moment of awesome is when the hero or heroine dies for the other; in the last episodes of Gosick, Victorique and Kujo take the harder path ... and go through hell to live for each other.
The Five Star Stories: Even though it took billions of years, Amaterasu and Lachesis are reunited and have a daughter, allowing mankind to continue evolution.
Kimi Wa Petto rewards Sumire and Momo with this after they struggle through their feelings, relationships and fight to keep each other in their lives.
So far in the Shakugan no Shana anime at least, almost every battle the good guys have been in were very difficult to win. The bad guys often had some kind of ace up their sleeve, and the good guys had to really fight, or exploit a weakness, in order to win.
The last season Shakugan No Shana Final was this trope; Yuji Sakai pulls a Face-Heel Turn in order to save the world knowing full well the ramifications of such an act and prepares to Walk the Earth as The Atoner before Shana calls him out and goes with him. FINALLY getting their happy ending in the process.It wasAwesome.
After putting the two title characters through hell in the second half of Tiger & Bunny, they both get a happy ending. Kotetsu betters his relationship with his daughter and resolves to not let his declining powers keep him from doing the job he loves. Barnaby gets to see his parents' murderer be brought to justice and finally finds a purpose in life (being Kotetsu's partner in superheroics) besides the quest for vengeance.
In Bakuman。, Mashiro and Azuki fulfill their promise and end up together, but it takes 10 years and four manga series by the main characters to get an anime, and Azuki has to prove herself worthy for the role, as well as weather some intense controversy after her relationship with Mashiro is leaked. The two of them also seem to invoke this trope, as Azuki once tells Mashiro that their happiness will be greater if they marry after their dreams come true.
With his timeline in ruins thanks to the androids, Trunks from Dragon Ball Z goes back and meets Goku and his father to warn them of the upcoming threat. Then he manages to take massive levels of Bad Ass in the Hyperbolic Time Chamber and also establishes a relationship with his aloof father Vegeta who gives him a sign of respect when he leaves. When he gets back to his timeline and easily destroys The Androids and Cell as well finally restoring peace to his timeline. I think its safe to safe he earned his Happy Ending.
From Pokémon Special, Blue and Silver easily have the most tragic childhoods out of all the main characters. both of them having been kidnapped when they were very little to be enslaved to become a mad man's personal soldiers. It takes a shit ton of effort on both their parts to take down the man responsible for their misery, and arguably even more effort to reunite with their parents after having been separated for over a decade. And when it turns out Silver's dad is Giovanni...
This trope applies to every character in A Cruel God Reigns, but most notably the two main characters Jeremy and Ian. Jeremy has to recover from the sexual and physical abuse he received at the hands of his stepfather in addition to living with the guilt of being a murderer. Over the course of all of this he also has to deal with his multiple Bungled Suicides, drug addiction, prostitution, post traumatic stress disorder, fear of emotions, trust issues, and chaotic relationship with Ian. Ian has to try to piece Jeremy back together, deal with his Broken Pedestal image of his father, his feelings for Jeremy and subsequent Gayngst, his fear of becoming like his Archnemesis Dad, and try to make sense of his family's past. Nadia has to learn to let Ian go and recover her relationship with her mother, Claire. Eric and Valentine have to communicate in secret after they are torn apart. Natasha has to live with herself after not saving Jeremy and at one point the stress weakens her to point of almost dying. And these are just SOME of the main plot threads.
In Anatolia Story, Yuri is kidnapped from her home and never does end up returning to her family or former boyfriend. She and Kail get involved in issues like wars or a plague, and watch as close friends and family die (by the time the series is over, the death toll includes Tito, Ursula, Rusafa, all of Kail's brothers but Jude, and Kail's father). They also suffer through Yuri miscarrying their baby, as well as every obstacle Nakia puts in the path of their relationship. By the story's end though, Nakia is discredited, Kail and Yuri are able to be wed, Yuri is crowned queen in Nakia's place, they discover that Yuri is pregnant again, and the closing narration tells how they ruled Anatolia well for the rest of their lives. As for their friends and allies who survived, the twins marry Kikuri and have four children with him, Hadi lives with them, Ilbani sees Kail's dream of a better country be realized (which was all Ilbani ever wanted in the series), and Jude and Princess Alexandra are wed.
Few happy endings have ever been as hard-earned as that of Mai Hi ME. Starting at the halfway point, what began as a generally light series becomes a battle royale, with character after character falling victim to the HiME Festival. Everyone Mai cares about dies or turns against her — and the Headmaster's plan, which brings them all back, couldn't have worked any other way.
