True Companions/Anime and Manga

The concept of True Companions is so ubiquitous in anime and manga that there's an actual word for it, Nakama. Here's examples:

"I can't leave her alone, because she's like family, I'll combine forces with her."
 * One Piece:
 * Monkey D. Luffy's crewmates. Especially evident in the Enies Lobby story arc, when
 * In the Whitebeard's War arc, a full-scale war between pirates and the government erupts just to save Ace.
 * As Whitebeard's
 * When Nami betrayed the crew and went over to Arlong cemented their Five-Man Band as a group of true companions, the crew fighting for her freedom despite the betrayal is probably the first real indication that they are a group of true companions.
 * At the end of the Water 7 adventure, it seemed to be a test of whether Usopp understood what it meant to be true companions.
 * At Thriller Bark
 * The core teenaged cast of Ranma ½ can possibly be interpreted as true companions, particularly in the later seasons and OVAs. This still didn't keep them from beating each other up at the drop of a hat, of course. A dramatic shift in the Ranma-Ryōga-Mousse dynamic took place during the Musk Dynasty arc. Since Ranma is locked as a girl, Ryōga and Mousse plot to let Herb kill her (or do so themselves) while they remove their own animal curses. However, when they start to put their plan to action, and it backfires, Ranma doesn't just fail to begrudge them, she actually yells at them to save themselves even as Herb is about to kill her. Later, Ryōga and Mousse come back to help Ranma unlock the curse and even save her life from Herb. Notably, and despite the unavoidable bickering and squabbling later in the series, the "bitter-rivals" relationship changed to "loyal-allies" after this event.
 * The cast of Tenchi Muyo! is another such example, although being that they are all related, if distantly and via fusion in places, the label for this is somewhat murky.
 * The main cast of Tantei Gakuen Q, i.e. the students of class Q.
 * Narumi and Masaru tend to develop these connections with those around them, most likely due to their family problems. Is it a Freudian Excuse if it has a positive result?
 * The Spider Riders of... well... Spider Riders. They even have an ancient prophecy about it.
 * Sailor Moon:
 * The Sailor Senshi. It's only fitting, consider how many suffer from Parental Abandonment. This is Lampshaded in the Image Song for Sailor Mars and Mercury called "Hottokenai Yo" (Loosely translated as "I Can't Leave Her Alone!"):


 * This was also one of the first things we learned about Sailor Uranus and Neptune's relationship to show they weren't just Sixth Rangers.
 * The Shitennou of the Dark Kingdom fit the example in the original manga. Kunzite, Zoisite, Nephrite, and Jadeite were like brothers and were visibly upset when members of the group were killed. In the anime, however, they were happy to backstab one another, except lovers Kunzite and Zoisite.
 * Ronin Warriors: the leads are True Companions. For the majortiy of them the Ronin are their family for all intents and purposes as their actual parents are either dead, or are physically or emotionally distant. This is largely subverted with the four Dark Warlords, who for most of the series don't give a damn about each other.
 * In Katekyo Hitman Reborn, Tsuna, Gokudera, Yamamoto, Ryohei, Hibari, Mukuro, Chrome and Lambo are true companions in a more literal sense of the term.
 * Star Driver: The Midnight Flight Drama Club were already true companions, but the arrival of Takuto seems to be bringing them closer and closer together.
 * The good guys in Dragonball Z are definitely true companions: they're all close friends, despite going anywhere from three to ten years without speaking to each other, and although Vegeta spends the rest of his life resenting how Goku beat him up, he eventually becomes part of the group.
 * This actually goes further back to the original Dragon Ball. It started out with just Goku and Bulma, then we have a bandit and his sidekick, and a pig who won't "behave" himself.
 * Furthermore, the original Chinese novel that inspired it, Journey to the West (which is where the "real" Son Goku comes from), is also an example.
 * The Ginyu Force could also count as True Companions, even more so between Burter and Jeice.
 * The core heroes of all six Digimon series. Although they don't always get along initially, they usually become true companions fairly early in the plot. Former villains or new characters may become true companions in the second half of the show.
 * The Bronze Saints from Saint Seiya, very much so. The Gold Saints to an extent too.
 * Every one of the sagas in JoJo's Bizarre Adventure depicts a protagonist group of true companions, but probably the third's (Jotaro Kujo, Joseph Joestar, Noriaki Kakyoin, Jean-Pierre Polnareff, Muhammed Avdol and Iggy) are the most close knit of them all. In fact, the ending of that saga is actually a Crowning Moment of Heartwarming, a considerable feat for such a violent, macho series.
 * Megumi's Instant Fanclub become her true companions in Tenshi na Konamaiki.
 * Fullmetal Alchemist has this all over the place.
 * After an amnesiac Greed kills Bido, Ling  demands to know why Greed killed someone who was supposedly his friend. Greed at first argues back that Bido was only that to the 'first Greed', but Bido's death by his own hands causes Greed to regain his memories and do a Big No, and subsequently, wanting to know what happened to his "possessions" and why King Bradley is in his memories. Of course, what made Greed mad wasn't that  killed his friends. It was that  killed his friends..
 * Mustang and his five closest subordinates are very much like this, in part because Mustang is A Father to His Men. Word of God says that by the time of the story, the six of them had developed a very tight familial bond after working closely together for so many years. Arguably this is particularly true of Hawkeye, who (to her knowledge) doesn't have any other living family.
 * To show how much Scar has developed, he refers to May Chang as this.
 * The Homunculi are literally family Out of the siblings, Lust, Gluttony, and Envy are the closest, with Gluttony and Lust the closest together, as shown by Gluttony's devastation when . This carries over into the 2003 anime version (despite the fact that Lust really didn't care about him; she just wanted To Become Human).
 * In Keroro Gunsou, Keroro refers to his team as true companions.
 * There is an entire episode of Martian Successor Nadesico dedicated to sending up the concept of true companions; it includes what is possibly one of the funniest sequences in the series.
 * Lottie in Soukou no Strain refers to her team as true companions and tries to convince Sara of such.
 * Naruto: A major theme is that the entire Leaf is this; the Will of Fire is the spiritual foundation which basically says the most important thing in life is being willing to risk your neck for someone else. It is not confined to the Leaf and many characters - Naruto, most notably - form such a bond with many people he meets. Most other villages have their own version of the Will of Fire too, if not its Martial Pacifist inclination.
 * Probably the most striking example is Shikamaru's speech to the squad retrieving Sasuke about how he personally didn't care much for Sasuke, but would try to bring him back anyways, because he was their true companion. Also a very good illustration of the nebulous nature of the term. The dub used "comrade", in the military sense of the term.
 * Of course, when Sasuke
 * Another example later in Naruto involves the difficulties Naruto and Sakura have accepting newcomer Sai to their team; despite his betrayal, they still see Sasuke as True Companions, and Sai is treated with much hostility as an interloper. (His grating, offensive personality doesn't really help matters.)
 * During the "Rescue the Kazekage" arc, while describing Naruto's bond with Gaara to Chiyo, Kakashi specifically uses the word 'true companionship.'
 * All of the teams named with numbers (Team 7, Team 8, Team 10) are groups of four people. Through the powers of Character Development, they all become tight-knit.
 * This is established early on by Kakashi, just after he passes Team 7 in his established test - he states in as many words that in the wolrd of ninja, although breaking the rules makes you "scum", adandoning your comrades makes you "worse than scum", and thus passes them for supporting each other. This theme only grows throughout the story.
 * The School Festival in Manabi Straight! has "from friends to true companions" as its theme. The "friends" in this case is a different Japanese word, tomodachi, which indicates a shallower level of intimacy.
 * The Genei Ryodan in Hunter X Hunter are a rare villainous example. Shooting Star City is a mix of Breakfast Club and True Companions on a mindbogglingly massive scale. Maintain some semblance of a society among the trash heaps of the world's largest landfill takes some teamwork.
 * Akira, Shuji, and Nobuta of the Japanese drama Nobuta wo Produce. Despite some romantic tension between certain members, the three generally function as true companions later in the series, and recognize themselves as such.
 * The five members of Beck. As Koyuki puts it in the final chapters: Ryusuke pulling him along through thick and thin, Taira always giving him the push to move forward, Chiba's cooperative spirit giving him strength and Saku always believing him. And they return the feeling in their own ways: thanks to Koyuki, Ryusuke relearned how to smile and take pleasure from his music; Taira learned to socialize with his friends; Chiba became more assertive to his surroundings; and Saku strived to become a better drummer due to the faith Koyuki had in him.
 * In Bleach, Ichigo and his circle of friends, including the shinigami and random defeated foes along the way.
 * Ishida often refuses to acknowledge the other members of the group as his friends, but goes to extremely great lengths to assist them, to the point that he once temporarily lost his supernatural powers and in several instances has nearly died.
 * And Rukia bitchslaps Ichigo for leaving her and Renji behind when he goes to Hueco Mundo, citing that exact same reason.
 * And surprisingly . The death of his true companions drove him serious. Kyoraku could be said to have similar motivations during that fight.
 * Chad fights for Ichigo and protects others because he was taught he shouldn't pick meaningless fights for himself, but Ichigo is mainly the reason for him doing this after they kicked ass together. Similarly, Orihime chose to join the Soul Society invasion because of her desire to protect Ichigo.
 * Squad 11 is sort of like a close knit group or dysfunctional family, especially the named members of the squad in the series, but all of them are true companions including the unnamed goons. In fact in their special closing credits image, where it's usually just the Captain and Vice Captain, the entirety of Squad 11 was there instead.
 * Ikkaku defines it perfectly by telling Shishigawara that, "There's no pecking order between men's lives! If you're going to risk your life, risk it equally! It makes no difference if it's for a boss or an underling, only die for those that would die for you!"
 * In Mirage of Blaze, both the Kagetora clan and the Uesugi army are eventually betrayed in favor of Haruie and Nagahide.
 * The student council candidates in Kujibiki Unbalance.
 * The Basketball Teams in Slam Dunk tend to be like this. There is also the Sakuragi's gang, who act as true companions when the plot calls for it.
 * The main characters of Red Garden. The girls all hang out with different cliques, and they never would've even spoken to each other if it hadn't been for Lise dying.
 * Both the Sanzo-ikkou and Kougaiji-ikkou in Saiyuki. While the latter are very open about it, the former will deny it until they're blue in the face. The Konzen-ikkou in Gaiden are somewhere in between: they're not as comfortable together as Kougaiji's group, but they're a much more cohesive unit than their reincarnations.
 * Yes! Pretty Cure 5 features true companionship-powered kamikaze mecha-butterfly. (Coco and Nuts get left out, though.) Featured as a logical expansion of the previous seasons' use of The Power of Friendship.
 * Higurashi no Naku Koro ni details what happens to True Companions if supernatural stuff starts eroding their bonds of friendship; the second season details exactly what they're capable of when it doesn't. Friends may help you move but True Companions help you move bodies.
 * In an episode of Hell Girl, Hone-Onna asks if Ren considers her and Wanyuudo to be True Companions, and is patently dismayed when he replies that he does not. He later mutters to himself that he actually sees them as kazoku, family, which implies that this is the only thing closer than a true companion. This is especially poignant as none of them actually have ever had families. Enma Ai is also considered a True Companions as well. They'd do anything for her, and her extremely rare moments of warmth are reserved for them.
 * Used extensively in Vandread.
 * The main cast of Yu Yu Hakusho.
 * Yes, even Hiei who might not seem like this most of the time. But after watching all of Chapter Black. You can tell he truly cares for his friends.
 * The Lagoon Company and Hotel Moscow in Black Lagoon, both to themselves and each other. Of course, the reason why the Hotel Moscow unit under Balalaika act the way they do is because they used to be a unit of the Soviet Army, and so therefore their bond is literally a soldier's bond. However, Balalaika's relationship to the Lagoon Company, a band of mercenaries that are not always on the same side as her, but who she is quite friendly to, is a good example of true companionship. Revy and Eda's relationship is another good example.
 * The five primary Blade Children in Spiral. It's worth noting that The Stoic Eyes is the one who actually uses the word "true companionship," when he tells Rio not to get herself killed.
 * Just about everyone in GetBackers forms some kind of complicated extended True Companions, with "That doesn't mean I like you" and "The second we're not being paid to work together, all bets are off" in full effect. The various members of the VOLTS hierarchy in the first Mugenjou arc are probably the best example, however. Emishi wanted to treat Shido to a good time before killing him because they were true companions once; later, after foiling his double-suicide attack, Shido drags him to the doctor. When asked why he would save an enemy, Shido smiles and answers that while they are enemies now, they used to be true companions; one day, they could be true companions again.
 * The five main characters in Inuyasha (Inuyasha himself, Kagome, Miroku, Sango, and Shippo). When Miroku and Sango
 * Mahou Sensei Negima
 * The Ala Alba, which is Negi's true companions group. Jack Rakan even explicitly refers to them as such.
 * Negi's father, Nagi, had the Ala Rubra, who were his true companions group.
 * For the students their club organizations tend to make true companionship-like bond. The two most clearly shown are The Library Exploration Club and the Baka Rangers (due mostly to their making up the core of Negi's Ala Alba). The Sports Girls have been getting a similar treatment since they took a bigger stage the latest arc.
 * Likewise, the tenants of the Hinata House in Love Hina qualify. Witness the way that every time one of them leaves, the others all go out to try to find them. Even Kanako, who joins up late and is initially hated by all of the others, ends up becoming part of the "family" by the end.
 * Also the main characters in Ai Yori Aoshi, which at first glance seems like a Love Hina clone. (They're very different in tone, though, as well as in their emphasis on realism vs. fantasy.) Completely understandable in the case of male lead Kaoru, in that he really has no family to return to. Several of the other characters have issues with their families, too.
 * The Band of the Hawk in Berserk certainly qualifies as true companions, especially later on in the anime. The leader of the Godhand, Void, uses the term "nakama" when they offer their Deal with the Devil to him during the Eclipse. Griffith's acceptance of their offer and betrayal of his true companions is one of the reasons why Guts wants him dead. Guts gains another group of true companions two years after the Eclipse, with Casca being the only survivor of the previous band (though given her traumatized post-Eclipse state, she's not going to be participating in any fighting anytime soon).
 * If you don't hear this in Fairy Tail, you're deaf, stupid or both. Comes complete with moments of "but s/he's your true companion!", among others. Being true companions is practically the whole premise.
 * Natsu tends to be the most vocal in terms of the True Companionship; nothing pisses him off more than a baddie who will either injure or kill their own team members, except possibly a baddie who attacks any of his closest friends.
 * True Companionship is even more so obvious [though not discussed/mentions as often] in Hiro Mashima's other (now less popular work Rave Master. Musica
 * Suzumiya Haruhi:
 * The SOS Brigade very gradually become true companions over the course of the novel series, in spite of three of them being secret agents with competing agendas and the other two being Kyon and Haruhi. Eventually it gets to the point where in one of the light novels, Itsuki tells Kyon that  Basically the same for Yuki. They were both heartwarming moments.
 * In the 11th book, Itsuki
 * Natsume Yuujinchou: Natsume Takashi has a group of ayakashi true companions.
 * The four main heroes of Chrono Crusade are like this, possibly to replace their lost family members (they're all orphans except for Chrono, who betrayed the members of his race twice-over). This is probably the reason why Chrono and Rosette don't become the Official Couple until the very end.
 * In the Chrono Crusade manga, the Sinners are shown in Chrono's memories to form an odd sort of family with Mary Magdalene -- which makes Chrono's eventual betrayal all the more traumatic to the rest, and also shows how ruthless Aion is when he proceeds to sacrifice them one by one for his goals.
 * Ouran High School Host Club:
 * The title group is portrayed as being like a family -- to the point that Tamaki calls himself "father", Kyouya "mother" and Haruhi his "daughter". When Tamaki begins to develop romantic feelings for Haruhi, he constantly denies them by focusing on their relationship as "father and daughter" (to the point of Squick levels for some fans).
 * Tamaki has an effect on all of them that he doesn't even realize; though they all have specific connections within their group, it's Tamaki's influence that ties them all together as one. Arguably, Haruhi also has this effect to a lesser degree, making her and Tamaki a bit of a power couple when it comes to group dynamics. There'd be shit going down if anything happened to any one of the Host Club, but if anything happened to Tamaki specifically, it'd be a full-on war with the rest of the world.
 * The Shuffle Alliance in Mobile Fighter G Gundam. Also, Argo and his pirate crew, which he specifically refers to as his "true companions".
 * The main cast of Azumanga Daioh. Miss Yukari and Nyamo interact with them regularly but are their own Heterosexual Life Partners unit.
 * The cast of Transformers Super God Masterforce forms a pair of these. Unusually, the true companions sense is more pronounced with the Decepticons, which eventually leads to.
 * Allen in D.Gray-man considers his fellow Exorcists his true companions. Even Kanda, with whom he is constantly having glaring matches when they're not fighting Akuma. Lenalee even more so. In fact, she has outright said that she doesn't honestly care about the world outside her true companions, so long as they are safe and happy she will continue to fight.
 * The six party members from Record of Lodoss War. The way their interpersonal dynamics go, it may be a dysfunctional one at times, but they definitely still count.
 * Monster Hunter Orage: The lead character takes this trope to absolutely absurd levels. His teammates even comment on this fact, with varying levels of annoyance.
 * Pokémon:
 * Really, Ash and all of his Pokémon party could be called this. It's part of the reason why he's a pretty good trainer, because he respects his Pokémon and they respect him.
 * Ash also forms a true companionship with his travelling companions, creating new bonds each time he travels to a new region. Arguably, since he's more than willing to befriend and/or help almost anyone he runs into, he's the nexus of an ever-growing super-true companionship of people and Pokémon across the known regions of the Pokémon World. Even his rivals grow to accept him as a companion.
 * Jessie, James and Meowth of Team Rocket also qualify; they share an extremely close bond that gets highlighted at least once a Generation. (They're also auxiliary (if troublesome) members of Ash's true companions, as numerous plots have shown.)
 * The regional trios (and Kanto foursome, counting Yellow) in Pokémon Special fit this Trope - the bond between the Sinnoh Holders, especially, is emphasized in the seventh and eighth chapters.
 * By the end of Baccano!, quite a few of the Immortal Lovable Rogues of the series (to wit: ) have forged one of these -- a huge contrast to the original set of the highly distrustful immortals in 1711 that had be scattered just to keep them from eating each other. Nice and Jacuzzi's gang is clearly one as well, though Jacuzzi seems to treat everyone like a member of his true companions.
 * Jin, Mugen, and Fuu in Samurai Champloo exemplify the trope, since Jin and Mugen are in a state of indefinitely delayed duel to the death, and refuse to let it go.
 * The five main characters from Tsubasa Reservoir Chronicle. Goes so far that at one point, trying to explain their dynamic to an outsider, Fai jokingly/seriously (the outsider can't tell which) says that Kurogane is Syaoran, Sakura and Mokona's father. The nicknames "Kuro-daddy" and "Fai-mommy" have since caught on in the Fandom.
 * Italy, Germany and Japan of Axis Powers Hetalia.
 * Fanon portrayed the Nordic countries (Sweden, Finland, Norway, Denmark and Iceland) as this in modern-day settings, and then they were confirmed as this trope in the Hetalia Bloodbath 2010.
 * In Paint it, White! while the Allies (except for Canada) and the Axis powers don't like the idea of working together, they still look out for each other when they're in danger of an alien invasion.
 * Celestial Being seems to become this in the second season of Gundam 00.
 * The Cyber Coil Detective Agency along with Daichi and Denpa make one big group of "true companions" in Dennou Coil. There are also a few smaller circles such as Tamako, Haraken and Yasako, but the most notable is Yasako and Isako, who come to have their own special true companion relationship.
 * The Deimon Devil Bats from Eyeshield 21 with Mamori as Team Mom and Hiruma as Team Dad / Drill Sergeant Nasty / Sociopathic Hero.
 * There's a few groups in Gintama that sometimes duke it out but sometimes overlap: The Yorozuya (Gintoki, Shinpachi, Kagura and Sadaharu), The Shinsengumi (Kondou, Hijikata, Okita, Yamazaki, etc.,) and the sort of disbanded Joui (Gintoki, Katsura, Takasugi and Sakamoto). However, by the end of the Benizakura Arc, it is pretty clear that whatever ties and sense of camarederie that  in the past have been completely broken, with both   pretty much declaring war on   for his actions.
 * In the manga Vagabond, the Yoshioka school of swordsmanship as a whole are essentially an independent samurai clan that, whatever their feelings about eponymous head and playboy layabout Yoshioka Seijuurou, are extremely devoted to his younger brother Denshichirou to the point that disciple Otagurou Hyousuke offers his arm (shattered in a training accident) as a "sacrifice" with which Denshichirou may proceed with his training, they accept senior disciple Ueda Ryouhei . Unfortunately this is the undoing of both themselves and the school, as.
 * Twenty's gang in The Daughter of Twenty Faces is like this. Chiko even thinks of Twenty Faces as her father, and refers to him as such at least once, and calls Ken "Ken-nii-chan" (roughly, "big brother Ken"). Even after episode 6, Chiko is a true companion with Shunka and Tome.
 * Magic Knight Rayearth: Hikaru, Umi and Fuu (plus perhaps Mokona) are this.
 * Riot Force 6 from Magical Girl Lyrical Nanoha StrikerS are this. It helps that Fate is a mother figure to Erio and Caro.
 * Hamel, Flute and the rest from Violinist of Hameln are this. It is actually stated within the manga that as most of the group had lost their mothers, Flute was like a mother to them.
 * The main cast of Clannad, of course; what were you expecting from a show where the main theme is "family?" Tomoyo even uses the actual term when she talks about what she considers to be the most important thing in life, obviously referring to Tomoya, Nagisa, and the rest.
 * Darker than Black: The Contractors of the MI6. The fact that one of them (July) refers to the group as such is even a significant plot point, as it's one of an increasing number of indicators that Contractors and Dolls aren't quite as soulless and exclusively self-serving as everyone thinks.
 * All three Yu-Gi-Oh!! series. In fact, one could say "true companionship" is the entire point of the series (other than them dueling of course). And the families the characters start out with grow with impressive speed. It's one of the 5D's buzzwords, along with 'kizuna' (bonds), 'kibou' (hope), and 'zetsubou' (despair) (the last for the villains of the second half of the current season. We're calling that Season Three? Or Four?)
 * The protagonists of Project ARMS fit this. At one point, they are described by an enemy as parts of a whole body (Yugo as the "ears", Kei as the "eyes", Takashi as the "legs", and Ryo and Hayato as the "arms"). In the anime, they jokingly refer to each other as "comrades in ARMS".
 * Debris Section, the heroes of Planetes, qualify, especially considering they spend all day, every day together and still hang out on their (rare) days off.
 * Brutally subverted in Jin-Roh: The Wolf Brigade. Given a choice between fleeing with his Love Interest or loyalty to his 'wolf pack',
 * The Girl Who Leapt Through Time has spades and spades of this trope. Makoto has a lengthy conversation with both her aunt and the two other members of her true companions group, Kosuke and Chiaki, about how their group dynamic would change if any of them started to date, be it outside their group or with each other. In fact, Makoto goes to incredible lengths with her time-traveling powers to prevent Chiaki from asking her out due to this.
 * Watanuki, Doumeki and Himawari from xxxHolic often make sacrifices for each other and some side characters end up falling into this as well.
 * Fushigi Yuugi: No matter how much crap and drama they go through, the Suzaku Seishi love one another to bits. This trope is shown in its extremity when.
 * Pandora Hearts: Alice at one point considers Oz, Gilbert and Break (and maybe Sharon too) to be this. It's quite cute. They demonstrate the fact that they're true companions left and right: saving Gil's hat, watching each other's backs, putting themselves at risk for each other, etc. And if you doubt Break or Sharon's being true companions, remember, it was Break who
 * The Kenshin-gumi (Team Kenshin) from Rurouni Kenshin are obviously true companions. Megumi even pictures her family when she sees Kaoru and Yahiko arguing.
 * The Gekkostate in Eureka Seven, who refuse to leave when Holland attempts to disband it to protect them, because they're a family. Aw...
 * The main Power Trio of Zettai Karen Children starts out like this. In the beginning Minamoto has to make a lot of effort to gain their trust and eventually they start to include him.
 * The four Links from the Legend of Zelda: Four Swords manga are understandably close. At the end, Vio even refers to them as  family.
 * Science Ninja Team Gatchaman: The Science Ninja Team. They are the five that act as one.
 * Ookami-san has one as its core cast.
 * Future GPX Cyber Formula's protagonist team, Sugo Asurada, are these towards the end of the TV series and the insert song in EP 17 drives the whole point home. However, it gets slightly toned down in the sequels, especially after the ZERO arc as the crew members are Demoted to Extra.
 * The crew of the Outlaw Star.
 * In Guyver, everyone who fights alongside Sho, especially Mizuki and Tetsuro who have been with him since the beginning. Even the Zoalords that aren't complete consters form their own true companionship.
 * In Excel Saga, Excel's neighbors develop from three roommates to six close, albeit dysfunctional, true companions, with reluctant Team Leader Matusya trying to get her entire team, not just herself, out of as much trouble their boss throws them into as she can.
 * The four major protagonists of Slayers, because of their rather anti-heroic natures.
 * In Uragiri wa Boku no Namae wo Shitteiru, the word true companionship is actually used often in reference to the Giou Clan.
 * Angel Beats!, especially Otonashi and Hinata from the start of the series, but the SSS in general is pretty tight, especially by episodes 11 and 12 when their response to is to simply give it a bit of thought, then all show up to fight with him anyway.
 * The "Afterschool Tea Time" of K-On! is a circle of very close friends first and a band second. They're so close that at the end of high school they all apply to the same college, with Mio giving up a scholarship to a prestigious university to do so.
 * The five protagonists in Ame Nochi Hare, brought together by their common affliction.
 * The cast of Rosario + Vampire definitely qualify, especially in the more recent chapters. Tsukune and the girls all care about each other very deeply, and have always been willing to go to great lengths for each other.
 * Takatsuki and Nitori in Wandering Son. Chiba was once a part of the True Companionship but eventually drifted away. Makoto may or may not be a part of the true companions depending on who you ask, though he's only really close to Nitori.
 * The crew of the Bebop from Cowboy Bebop, which makes their all the sadder.
 * Ayumu and Miki in Life.
 * The Searchers from the Monster Rancher anime.
 * In Saint Beast, the eponymous six Saint Beasts. Unfortunately.
 * The entire Occult Research Club in High School DxD is this. Harm anyone of them and the others will kick their enemies ass.
 * Historys Strongest Disciple Kenichi abounds with them on both the protagonist and antagonist sides. Most notable are the masters of Ryouzanpaku and the Shinpaku Alliance. Its even lampshaded by a character that the Shinpaku Alliance exudes "the melody of friendship".
