Last Name Basis / Anime & Manga

Go To

Examples of Last-Name Basis in anime and manga.

It is worth noting that family names come before given names in Japanese, Chinese and Korean usage.

  • Unlike his best friend/eventual nemesis Tetsuo Shima, Shotaro Kaneda is always referred to by last name in AKIRA (to the extent that it's easy to forget he even has another name).
  • Rurouni Kenshin has several characters referred to only by their surname, namely Shishio, Saitou, and Hiko. Misao is one of the few to usually address Kenshin by his family name "Himura".

  • In Blue Seed, Yoshiki Yaegashi, Daitetsu Kunikida, and Azusa Matsudaira are all referred to by their last names. While in the original Japanese dialogue their first names are never invoked, the English dub interestingly used their first names as a tool to denote a new level of intimacy regarding the romantic relationships of those three characters. Thus in the English dub Matsudaira is called "Azusa" by her ex-husband, Yaegashi is called "Yoshiki" by Koume when they start a relationship at the end of the series and again when they get engaged in the OVA, and Kunikida is called "Diatetsu" by Ryoko when they begin dating as well.
  • In Full Metal Panic!, Sousuke calls everyone by their last names, mostly because of military discipline, and has actually had to be ordered to use first names.
  • Neon Genesis Evangelion:
    • Rei Ayanami and Shinji Ikari both do this with each other; he only says her first name in unusual situations. This is one of the things changed in the English dub.

    • Gendo (when people aren't calling him "Commander" or "Father") and Fuyutsuki are always called by their last names.
    • For some reason, nobody — not even the fans — uses Kaji's first name, Ryouji, to the point where said name is only mention in dialogue at one point, when Misato gives him a Full-Name Ultimatum. He also only ever calls Misato "Katsuragi", unusual considering they used to date each other.
  • Fullmetal Alchemist:
    • Lt. Colonel Hughes is referred to so rarely by his first name (Maes) that the casual fan or someone who hasn't seen very many episodes would probably only know him as "Hughes."
    • This seems to go for a good chunk of the military characters, actually. Even when screaming to each other in fear or pain in the manga, about 85% of the time or more, it's either the rank or the last name.
    • The only reason anyone would know Mustang's first name is the fact that Hughes seems to always refer to him on a First-Name Basis. Roy also seems to be the only person to ever address Hughes as Maes.

    • There are two Armstrongs: Major Alex Louis Armstrong, and his sister General Olivier Mira Armstrong. Fans usually refer to Alex as "Armstrong", since he was introduced much earlier, and he's a guy while she's a girl, and Olivier as "Olivier" (or "Olivia"). The series generally differentiates them by their ranks: Major (Alex) vs General (Olivier). Nobody in the series ever calls Alex by his first name (other than his sister).
    • Late in the manga, Hawkeye smokes out Envy impersonating Mustang by claiming that:
      Hawkeye: When we're alone, the colonel always calls me 'Riza.'
      Envy: Damn! I knew you two were—
      Hawkeye: I Lied. Thanks for blowing your cover. *bang*
      • They almost exclusively use each other's ranks, only rarely bothering even with surnames.
    • The only person in the military who's most often referred to by his first name is Edward Elric, who is both significantly younger than the other military members and consistently travels around with his brother of the same last name. The only person who doesn't is Mustang, who usually calls him Fullmetal/Hagane.
  • In Death Note, all of the police officers (the ones that join L's forces) refer to each other by their surnames. The exception being Soichiro who's either referred as "Chief" by the remaining four taskforce members and "Mr. Yagami" by L and Watari and Light who's addressed by his first name.
  • A few characters from Your Lie in April are rarely referred to by their first name, not even by their close friends.
    • Watari Ryota.
    • Kashiwagi Nao.
  • Azumanga Daioh:
    • Sakaki and Kagura are only known by their family names; no given names are ever shown for them, leaving fanfic authors with a few problems. (At least one fic has ended up having Kagura's father calling her just 'Kagura' in one scene.)note 
    • It's possibly worth mentioning, in the few scant minutes of screen time Ayumu had before being nicknamed after her (not)hometown, she was called "Kasuga" by Yomi. Would she have continued to be called by her family name instead of her given name had Tomo not been quite so clever? The world may never know...
  • Signum of Lyrical Nanoha always refers to Fate as "Testarossa". Since Signum calls everyone else by their first name, and she and Fate are close friends, this seems to be treated as a term of endearment and/or respect for her long-time rival.
    • She continues to call Fate this after Fate's last name stops being "Testarossa".
      • Except the "Testarossa" name never completely disappeared; it just got turned into a middle name, usually rendered as just an initial (but explicitly stated at least once).
      • Vita also calls Fate "Testarossa". Shamal initially refers to Fate as "Testarossa-chan", but by StrikerS, starts calling her "Fate-chan".
    • In the StrikerS supplementary manga, Subaru initially calls Teana "Lanster-san", and Teana refers to her as "Cadet Nakajima" while explaining that they do not need to become friends. After Teana meets Subaru's sister Ginga and learns more about her, she decides to start calling her Subaru, claiming that it makes no sense to call her by her last name now that she knows her sister, and Subaru decides to start calling her "Tea". Erio and Caro initially have a bit of trouble calling each other by their first names (even though they're technically siblings).
    • While Nanoha, Fate and Hayate are usually on a First-Name Basis, while on duty, they'll switch to last names and titles as appropriate.
    • In ViVid Strike!, Jill refers to most of the martial artists by their last names with the "-senshu" honorific (literally "competitor"). The only exception is Jill's own protégé, Rinne, whom she calls by her first name. Jill also refers to Nove, head of the Nakajima Gym, as "President Nakajima."
    • Youhei Sunohara usually goes by his last name with the exception of his little sister Mei and Kyou. Then again, Kyou calls everyone by their first name.
    • It's also a subtle plot point in Kyou's route. Tomoya calls her Kyou, but he calls Ryou "Fujibayashi", which she tries to get him to change because he feels he isn't as close to her as Kyou and loves her sister instead. He does start calling her Ryou, but... Well, it is Kyou's route.
  • In Mobile Suit Gundam Wing, Lucrezia Noin goes by her last name, and nobody, not even her romantic interest Zechs, uses the first unless they're calling her by her full name. (Fanon often has Zechs give her a cute nickname, such as "Lu", when they become a real couple.) This is actually by Noin's own request: when Treize tries to call her by her first name in a prequel manga, she actually corrects him and says that one's gender does not matter in the battlefield so he should make no distinctions in regards to her.
  • in Kare Kano, the two leads continue calling each other "Arima" and "Miyazawa" after they've slept together. They don't get to "Soichiro" and "Yukino" until a few months later.
  • This is very common in Yu-Gi-Oh!, especially in the Japanese version. Some characters who are referred by their surnames and have relatives, those relatives are referred by their first names instead (e.g. Mokuba or Rudger). Only a few characters are referred by their surnames in the 4Kids dubs.
    • Yu-Gi-Oh!: Jonouchi, Honda, Kaiba, Bakura, Otogi, Haga, Ryuzaki, Kakjiki, Roba, Kotsuzuka, Mr. Crocketts, Saruwatari, Hanasaki, Ushio, Sozoji, Inogashira, Kokurano, Nagumo, Imori, Nezumi, Chono, Tsuruoka, Karita, Hirutani, Yoshimori and Kanekura.
    • Yu-Gi-Oh! GX: Manjoume, Kenzan, Misawa, O'Brien, Fujiwara, Daitokuji, Samejima, Kagemaru and Saiou.
    • Yu-Gi-Oh! 5D's: Goodwin, Kiryu, Ushio, Mizoguchi and Heitmann. Most characters (including Yusei) called Aki by her last name Izayoi before she joined the heroes. Jack still calls her "Izayoi". Jack is often called "Atlas-sama" by his female fans.
    • Yu Gi Oh Zexal: Shingetsu and Yamikawa.
    • Yu-Gi-Oh! ARC-V: Gongenzaka, Sawatari, Kurosaki, Nakajima, Ishijima, Ankokuji, Kyuando, Kachidoki, Takeda, Umesugi, Kakimoto, Ootomo, Yamabe, Tokumatsu and Roget.
  • Shuichi in Gravitation continues to refer to boyfriend Eiri Yuki as simply 'Yuki' (no honorific) even after learning that it isn't his real surname.
  • Naruto rarely does this, with some characters, like Gaara, referring to Sasuke as "Uchiha." The Third Hokage is often referred to by his last name until his first name is revealed in the databooks, although in one translation, The Fourth Hokage calls him "Hiruzen-sama." Shiho calls Naruto "Uzumaki-kun", while referring to Shikamaru (whom she has a crush on) and Jiraiya (who only has one name) by their given names, so it's unclear to what degree she uses last names. Rock Lee is always either called "Lee" or "Rock Lee", never just "Rock".
  • Haruhi Suzumiya:
    • In the novels, Kyon refers to everybody except Haruhi by their last name. In the ninth novel, he strangely also calls the mysterious interface, Kuyo, by her first name.
    • Kyon is confused as to which of Kuyo Suo's names is her given name and which is her surname when they are introduced, as she introduces herself in both orders; he calls her Kuyo-san most likely because that's what Sasaki calls her.
    • Also worth noting is that he never uses honorifics when addressing or speaking about anyone other that Mikuru Asahina. He also continues to refer to her as "Asahina-san" even though she told him to feel free to use her given name early in the series. He does use honorifics with the upperclassmen (which Mikuru is), but it's almost always -san and not -senpai; in later novels he starts to refer to Kimidori as "Kimidori-senpai".
    • Most fans also refer to Itsuki and Yuki as Koizumi and Nagato, respectively. Speaking of which, Itsuki is almost never referred to by his first name.
    • Haruhi refers to the entire Brigade (including Yuki) by their first names, except Koizumi, which is probably why most fans ended up doing the same.
    • Several characters in the series aren't even given first names. Tsuruya, Kunikida, Taniguchi, Sasaki...
    • Yuki Nagato rarely refers to others by name in the main series, but in The Disappearance of Nagato Yuki-chan, refers to most people by their last names, even calling her close friend Ryoko "Asakura-san", and most people refer to her as "Nagato-san".
  • Bleach:
    • Ichigo Kurosaki, Orihime Inoue and Uryu Ishida are on a Last-Name Basis with one another. Rukia is on Last-Name Basis with the gang except for Ichigo and Renji. Ishida is on Last-Name Basis with most everyone (excluding some minor characters), and the only people who refer to him by his given name in the original Japanese are his father and grandfather (and later Pesche). Following up on that, nearly every Shinigami in the series addresses the entire gang exclusively by their surnames, aside from Yoruichi (to Ichigo), Rangiku (to Ichigo, Renji and Orihime), Ikkaku and Yumichika (to Renji, Ichigo and "Orihime-chan"), and Kenpachi (with Yachiru; to Ichigo).
    • Captain Toshiro Hitsugaya is very particular about this, although he tends to insist that people also address him as a captain. Interestingly enough, in an inversion of people discarding Last-Name Basis as they get closer, Momo told him that she would call him by his last name after he got into the academy.
    • With or without addressing their respective ranks, most seated officers call one another by their surnames (such as Ukitake and Kyoraku), with the majority of the fandom following suit; aside from characters who are related by birth (the Kuchikis or Kotetsus), they call every other officer by their surnames.
    • Orihime herself tends to address everyone except "Tatsuki-chan" (and later "Yachiru-chan", "Riruka-chan" and "Yukio-kun") by their last names.
    • When Ryuken Ishida calls Isshin Kurosaki by his last name with no honorific, Isshin says that's downright cuddly by Ryuken's standards.
    • The potential for this to be inconvenient is lampshaded in 473, when Hitsugaya is talking about Byakuya and Rukia Kuchiki.
    Hitsugaya: I don't see Kuchiki and Kuchiki.
    Ikkaku: Could you use their first names? It's a little confusing.
    • In the Everything But the Rain flashback arc, Katagiri's first name wasn't immediately introduced. Everyone referred to her by her surname. For her part, being the Ishida family's maid, she doesn't even refer to Ryuken and his parents by name at all (his parents are the Master and Mistress and he's the "young master"). She makes an exception for Masaki, however, by referring to her as "Masaki-sama", and in one conversation calls Ryuken "Ryuken-sama" to emphasise that he really needs to listen to what she's telling him. He does. Her first name, Kanae, is only revealed when Isshin, who's telling this story, clarifies to Ichigo that Kanae later became Ryuken's wife and Uryu's mother... and died around the same time Masaki kicked it.
    • The English dub performs a bizarre subversion mid-season. For the majority of the series, everyone refers to him as "Aizen," but in the middle of the Fake Karakura arc, without any explanation, the cast are suddenly on a First-Name Basis with their most hated enemy. What makes this even stranger is that Shinji called Aizen by his first name while Aizen was his lieutenant, but switched to "Aizen" after Aizen betrayed him.
  • In YuYu Hakusho, most characters call Kuwabara by his last name, except for his sister and Yukina. Shinobu Sensui tends to go by his last name most often, and this is significant because his first name changes based on which personality is in control.
  • Although most of the children are on a first name basis in Digimon Adventure/Digimon Adventure 02, Miyako always calls Koushirou "Izumi-senpai." Ken, the Sixth Ranger of the latter, seems to be the other main exception. Most of the children refer to him as "Ichijouji" at first and he usually refers to the others by their last name. He and Daisuke go back and forth for quite a bit, although some of the others (such as Miyako) end up referring to him by his first name and he does the same to a few others.
    • In the dub of the first episode of Digimon Adventure lists the full Japanese names of the characters, but Izzy (Koushiro Izumi) is the only one whose Americanized name is based on his Japanese surname. Even his parents call him Izzy.
In Digimon Tamers although Guilmon, Culumon and Impmon refer to Juri by her first name after meeting her, Takato never does despite having a crush on her. He always calls her "Kato-san". Her Digimon, Leomon also does it at first when meeting her. Hirokazu, Kenta and Lee do it as well, but Ruki does call her "Juri".
  • The typical mode of address in Muhyo and Roji. Tohru Muhyo allows Jiro "Roji" Kusano to call him "Muhyo" instead of "Executor Muhyo".
  • Almost non-existent in One Piece, due to relatively few characters even having last names, but some of Zoro's opponents call him Roronoa.
    • Shackey calls Luffy "Monkey-chan", and Smoker refers to a lot of pirates by their last name, for example Law. Interestingly, the three most recent characters with first and last names (Ho(r)dy Jones, Ikaros Much and Caesar Clown) have been referred to with their last names (Ho(r)dy, Ikaros and Caesar) as if they were their first names.
    • Law is called by his family name Trafalgar by the other Supernovae, e.g. Kid and Luffy. Luffy and his crew usually use a nickname based on Law's family, but it's still basically this trope.
  • First names are a rarity to begin with in Legend of Galactic Heroes, but absolutely nobody calls Yang Wen-Li by his given name (except his father, in a single flashback). Even his friends whom he calls by their first names call him "Yang." His wife just calls him anata (roughly, "darling").
    • Reinhard calls Kircheis by his last name because as a child he decided that it sounded better than his first name (Siegfried). Kircheis, however, calls Reinhard by first name (with the appropriate honorifics, of course).
  • An understandable standard in Monster, since most characters are in the professional field and do not know each other that well. The only person who ever seems to call (Kenzo) Tenma by his first name is his fiancee.
  • Lucky Star:
    • Kagami Hiiragi realizes how much time she spends in Konata's class after a short scene showing her own class calling her Hiiragi while Konata's calls her Kagami. She herself also refers to Misao and Ayano respectively by their last names Kusakabe and Minegishi, even though she's been friends with them for longer than with the other core characters.
    • Miyuki alternates between Konata's name and surname when referring to her.
    • Yutaka sometimes calls Minami, her closest friend, by her last name Iwasaki. She at some point realizes how much of a habit she made of this.
    • Both she and her other friends tend to refer to Hiyori as Tamura-san. Hiyori herself also addresses Yutaka and Minami by their last names.
    • Nanako Kuroi, being a teacher, is mentioned most commonly as (Ms.) Kuroi by other characters (except for Konata, who calls her "Teach", and herself addresses her students by their surnames.
    • The manga-exclusive Tamaki Yamanobe addresses her friends by abbreviated, honorificized versions of their last names, such as Buu-san (Miku Busujima), Kobacchi (Yutaka Kobayakawa), etc. (except for Patricia, whom she calls "Paa-chan").
  • Kanda Yu of D.Gray-Man tends to threaten people who don't address him this way with violent death.
  • In Mahou Sensei Negima!, Kazumi Asakura usually goes by "Asakura", which is strange, given that practically everyone else in the class calls each other by their first names.
  • In Lupin III; (Arsene) Lupin the Third, (Daisuke) Jigen, and (Koichi) Zenigata might as well have Only One Name for all the times anybody's used their given names in the show. Goemon Ishikawa the Thirteenth and Fujiko Mine, on the other hand, mainly go by their first names. Odd in Goemon's case, because the rigidly traditional character takes no offense at complete strangers speaking to him by his given name.
  • Otonashi, Iwasawa, and Naoi from Angel Beats!! are always referred to by their last names, even after their first names are revealed ( Yuzuru, Masami, and Ayato, respectively).
  • Surnames are said to be uncommon in the world of Dragon Ball, but the main character, Son Goku, has one. While most characters refer to him as Goku, his given name, Bulma, his first friend, refers to him exclusively by his surname (but not in the dubs where his last name is never even mentioned). Piccolo and Tenshinhan often do the same but not always.
  • Except for a few racers and characters in Future GPX Cyber Formula, most of them are rarely called by their first names, like Naoki Shinjyo, Karl Lichter von Randoll, to name a few.
  • Yamato of Karakuridouji Ultimo refers to his crush Sayama by her last name, and at one point, while thinking about what life with her would be like in the future, realizes that her name would not be "Sayama" any more.
  • The general rule between people in Bakuman。, even (so far) between Mashiro and his fiancee Azuki. Mashiro and Takagi refer to each other by nicknames while speaking with each other, but with last names when talking about each other to other people, such as their editors.
    • When Hiramaru gets together with Aoki, he notices that she's still calling him by his last name, while he uses an abbreviated and highly affectionate version of her first name. His editor claims that's proof that he's just a friend she has for tea, in order to manipulate him into becoming depressed enough to write well.
  • In Triangle Heart 3: Sweet Songs Forever, most characters address each other by first names, but interestingly enough, Kyouya and Shinobu, the Official Couple, refer to each other by their last names.
  • The main character of Dawn Tsumetai Te is only ever referred to - by his friends, his Love Interest, and his Jerk Ass Mad Doctor handler - by his family name.
  • In Happy Yarou Wedding, Yuuhi never makes the switch from calling his lover Todou to Akira, even when he becomes a part of the family and Todou becomes his last name.
  • In A Certain Magical Index/A Certain Scientific Railgun: Kaori Kanzaki, Mikoto Misaka, Ruiko Saten, Kazari Uiharu, sometimes Touma Kamijou and a few others. Special mention for Kazari and Ruiko: They're pretty important characters, and appear a lot, but nobody ever calls them by their first name.
  • Yurie in Kamichu! generally addresses Kenji as Ninomiya-kun, though she switches to Kenji-kun in the scene where she reaches out to rescue him from the typhoon she accidentally created. Unusually, the English dub retains this.
  • Puella Magi Madoka Magica:
    • Mami typically refers to her fellow magical girls as "(Last name)-san", partly out of politeness and partly because while she gradually becomes closer to Madoka and Sayaka, she never quite gets past being an acquaintance to them before she is eaten. Madoka becomes suspicious of Hitomi's behavior when she, under the effects of a Witch's Kiss, refers to her by her last name and speaks in a much more formal tone: she is a very polite speaker normally, due to her high-class upbringing, but up until then she had always addressed her and Sayaka by First-Name Basis plus "-san".
    • Homura, in the earlier timelines, calls the other magical girls by their last name and -san. While Mami's use of Last-Name Basis was not carried over to the dub, Homura's was (for example, calling Madoka "Miss Kaname").
  • Despite being the Official Couple of the Bakemonogatari series, Hitagi refers to Koyomi as Araragi-kun, while he calls her Senjogahara-san
    • In addition, Hanekawa and Kanbaru are almost exclusively referred to by their last names.
  • On Soul Eater, pretty much everyone calls Dr.Franken Stein by his last name, along with the title occasionally.
  • Canon Foreigner Sanae Demokori from Love, Chunibyo & Other Delusions anime seemed to prefer to be called by last name, even among her classmates ("Deko-chan"). Nibutani is also almost exclusively referred to by her last name.
  • This is the standard way of reference in Kotoura-san, even between Haruka Kotoura and Yoshihisa Manabe, which are already having a stable relationship.
  • The eponymous Armitage of Armitage III. We find out fairly late in the series that she does have a first name, but no-one ever uses it.
  • Cardfight!! Vanguard has (Toshiki) Kai, (Taishi) Miwa, (Katsumi) Morikawa, and (Yuuta) Izaki. However, we only ever learn Miwa and Izaki's first names in the credits. Meanwhile, everyone else is known by their first names (although some characters call Aichi Sendou by his last name).
  • In ×××HOLiC, both Watanuki and Doumeki are rarely if ever referred to by their first names (Kimihiro and Shizuka respectively). Doumeki himself never calls anyone except for Yuuko by their first name, (though to be specific, he never calls anyone anything except the first name he knew them as, as he'll continue to call girls by their maiden name even if they've married).
  • The Sweets Princes in Yumeiro Pâtissière are on a last name basis with each other: (Makoto) Kashino, (Satsuki) Hanabusanote , and (Sennousuke) Andoh. While the latter two refer to Ichigo as "Amano-san", Kashino, being the kind of person he is, prefers to call her "Amano".
  • In Kimagure Orange Road, Kyosuke always refers to Madoka as "Ayukawa", while she calls him "Kasuga-kun". This remains even after they finally get together and it's only dropped in the Shin Kimagure Orange Road novels and movie; in the first, it's via a scene where she points it out and Kyousuke switches to First-Name Basis via shouting her name to the skies.
  • In Girls und Panzer, most of the girls who don't know each other well refer to each other by their last names.
    • Yukari calls most people by their last name and the extremely formal "-dono". She's also the only person to call Sodoko by her actual last name outside of introducing her.
    • In one scene, Hana gets Yuzu's last name correct while addressing her as "Koyama-senpai," but mistakes her first name for Momo's.
    • Miho starts out calling all her friends by their last name and -san, but switches to first name and -san about a third of the way through the series.
    • In Little Army, Emi calls her friends by their last names and -san, even after they start calling her "Emi-chan". As she's saying goodbye to Miho, she calls her by her first name.
  • Gunslinger Girl. Victor Hilshire is only addressed by his last name, even by his fellow handlers. His cyborg Triela doesn't even know what his first name is until halfway through the series, when his girlfriend happens to mention it.
  • The main characters in Monthly Girls' Nozaki-kun go by their last names almost exclusively to the point that it's sometimes hard to remember what their first names are! Sakura is possibly the only exception, as both Seo and Kashima call her Chiyo (and so does the mangaka herself). The only characters that are frequently called by their first names are Nozaki's editor Ken Miyamae, as Nozaki calls him Ken-san, and Nozaki's younger brother Mayu Nozaki, so as not to confuse him with Nozaki himself.
  • In Sgt. Frog, Fuyuki always refers to Momoka Nishizawa as "Nishizawa-san".
  • In Area no Kishi, this trope presents a dillema when Nana Mishima joined the jr. high soccer team. Because there was another Mishima on the team, saying "Pass to Mishima" could cause confusion. This resulted in coming up with a nickname for her: "Seven"note .
  • This is common in most military themed anime. This happens in a few mecha anime as well, such as the original Golion.note 
  • In Angelic Layer, while Kotaro Kobayashi prefers to refer to Misaki as "Suzuhara", Tamayo prefers that everyone refer to Misaki as "Misakichi".
  • In Binan Koukou Chikyuu Bouei-bu LOVE!, Arima's firt name Ibushi is easily forgotten because everyone else complies with this trope.
  • In Ranpo Kitan: Game of Laplace, characters are introduced using only their last name, so everyone gets this. Even the official site doesn't give their first names.
  • No one in Wandering Son refers to Nitori Shuuichi or Takatsuki Yoshino by their given names besides their family members and Nitori's girlfriend. It could be because they're transgender and don't like their names but we never see them tell anyone not to use their names, and them being trans is a secret for much of the series. Almost all their other friends are on a First-Name Basis so it's even more noticeable. Chiba Saori is usually referred to by her surname as well, though Kanako uses "Saorin" as an Affectionate Nickname.
  • Togo Mimori from Yuki Yuna is a Hero is only referred to as "Togo" or "Togo-san" despite being on a First-Name Basis with all her friends. Episode 10 reveals that when they first met her closest friend (and crush) Yuuna uses it because she thinks "Togo-san" sounds cool.
  • All of the main characters in Ojojojo call each other by their last name despite being close friends. The only major exception to this is Chris, and even then it's because he initially introduced himself in Western name order and they mistook his first name for his last one. Haru and Tsurezure don't switch to First-Name Basis until a few months after they started dating.
  • Assassination Classroom: Most character in Class 3-E are called by their last name for about 90% of the time. Exceptions are Nagisa, Karma, Ritsu (which is simply a nickname for her Overly Long Name) and Itona.
  • Shokugeki no Soma: Most characters are referred by their last name for the majority of time, but there are also plenty of First-Name Basis examples as well.
  • Ririka from Nurse Angel Ririka SOS gets mad at her friend Seiya because he refers to Kanou as "Nozomu" instead of "Senpai".
  • Keitaro of Love Hina never calls Naru by her first name, even after they get married.
  • Kobayashi of Miss Kobayashi's Dragon Maid is never called by her first name, in fact it's never even been revealed.
  • Kaguya from Kaguya-sama: Love Is War refers to just about everyone by their last name, no matter how close she is to them (even Hayasaka and Ishigami). She even makes a mental note when she addresses Kei by her first name, noting that it's the first time that she's ever done so for a non-family member.
  • For the most part, Last Name Basis is common in Interviews with Monster Girls, as would be expected in a Japanese school setting. There are some exceptions, as kids are more casual among themselves and Takanashi doesn't mind his students having a nickname for him. Chapter 15 hangs a lampshade on the trope when Kusakabe notes that Takahashi only refers to Hikari by her given name. Hikari, in turn, refers to Takahashi simply as "Sensei", instead of "Takahashi-sensei" or his nickname. Takahashi says at first it's to differentiate her from "Himari-chan", only for the girls to pick up on the use of "chan" for Himari and no honorific at all for Hikari. What follows is a sequence of Takashashi referring to Hikari as "Takanashi", making Hikari wonder if she's in trouble, "Hikari-chan", making the Genki Girl respond with extra Genki, and just "Hikari", which gets her to respond naturally. The narration notes that it's simply become too habitual to change now. In the course of the chapter, Takahashi also refers to Kyouko Machi and Yuki Kusakabe by their first names. The former explodes in embarrassment and the latter ends up finding it awkward, despite being the one who first brought it up.
  • 5 Centimeters per Second: One of the signs that Takaki never feels anything for Kanae is that he always calls her by her surname, whereas he addresses Akari by her given name.
  • In Haven't You Heard? I'm Sakamoto, it's unknown what Sakamoto's first name is. He did reveal it one time, but it was drowned out by noise.
  • Bokurano has this happen fairly often.
    • All the military characters, government officials and other adults are generally only referred to by their surnames.
    • While some characters are exclusively referred to by their first names, and others by nicknames, still others- Kako, Waku, Moji, Kirie, Machi and Ushiro- are referred to by their last names by anyone who isn't a family member.
