History LastNameBasis / AnimeAndManga

* On ''SoulEater'', pretty much ''everyone'' calls [[CombatMedic Dr.Franken Stein]] by his last name, along with the title occasionally.

* In ''FullmetalAlchemist'', 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."
*** Besides, in Spanish "Maes" sounds a lot like "Maese" which is a rather archaic term that was used as "Master" to respectfully address someone, specially in old written media, so you could think that 1) he was being very polite and 2) it would be nice if we could know his first name. Then again, only if you have read old books and are familiar with the word.

** There are two Armstrongs. It could get potentially confusing.
*** Usually, Alex Armstrong is referred to by fans as Armstrong (since he was introduced much earlier) and Olivia Armstrong is referred to as Olivia ([[SpellMyNameWithAnS or Olivier]]). They are also sometimes differentiated by their ranks: Major Armstrong (Alex) vs General Armstrong (Olivia). Nobody ever calls Alex by his first name.
**** Well, nobody except Olivier, but they're siblings, so that doesn't count.

-->'''Hawkeye:''' Fooled you. *bang*
*** They almost exclusively use one another's ranks, only rarely bothering even with surnames, to the extent that Riza addressing some other colonel or Roy being promoted to general or something would pose a minor emotional challenge, although there are enough lieutenants around that Roy can't identify it with her so closely. In this case at least this serves rather like the Mulder and Scully situation [[ProperlyParanoid mentioned below]].
** The only person in the military who's refer to by his first name is Edward. The only person who doesn't is Mustang.

* In {{Bleach}}, Ichigo (Kurosaki), (Orihime) Inoue and (Uryu) Ishida are on a LastNameBasis with one another, including (Yasutora) Sado, though he does call Ichigo by his first name (Ichigo misread "Sado" as "Chad", so that more or less counts). Rukia is on LastNameBasis with the gang except for Ichigo and Renji. Ishida is on LastNameBasis 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).

* 25th Baam from ''TowerOfGod'' calls his best friend, Koon Agero Agnis, simply Mr. Koon.

* It is worth noting that family names come before given names in Japanese usage.

** Though it can be noted that in Manga/OnePiece pirate crew titles function much the same way as last names. Luffy's opponents rarely call him Luffy, or even Monkey (thank god, that would sound ridiculous) but instead tend towards calling him Strawhat. Franky, who started out as a villain and got used to this, still calls him that. Other examples include Whitebeard and Redhair. Shanks switches abruptly to this from being on last name basis with Edward D. Teach when he meets him for the first time since he has adopted the title of Blackbeard. Played straight with Rob Lucci, and a few other villains however. Ruthlessly averted with Garp and Roger, both of which always go by their first names, and no titles at all.

* Despite being the OfficialCouple of the ''LightNovel/{{Bakemonogatari}}'' series, Hitagi refers to Koyomi as Araragi-kun, while he calls her Senjogahara-san

* In ''GundamWing'', 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.

* In {{Bleach}}, Ichigo (Kurosaki), (Orihime) Inoue and (Uryu) Ishida are on a LastNameBasis with one another, including (Yasutora) Sado, though he does call Ichigo by his first name (Ichigo misread "Sado" as "Chad", so that more or less counts). Rukia is on LastNameBasis with the gang except for Ichigo and Renji. Ishida is on LastNameBasis with most everyone (excluding some minor characters), and the only person who refers to ''him'' by his given name in the Japanese version is his father (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).

* In FullMetalPanic, Sousuke calls everyone by their last names, mostly because of military discipline, and has actually had to be ordered to use first names.
* In ''NeonGenesisEvangelion'', Rei Ayanami and Shinji Ikari both do this with each other; he only says her first name [[SayMyName in unusual situations]]. This is one of the things changed in the English dub.

* ''YuGiOh'' has a lot of this. In the Japanese version and manga, characters such as KATSUYA Jounouchi and HIROTO Honda fit, and tend to only get their first names used by family. The tendency to refer to Kaiba by his surname carries over to the dub.

* The first episode of DigimonAdventure lists the full Japanese names of the characters, but Izzy (Koushiro Izumi) is the only one whose Americanised name is based on his Japanese surname. Even his parents call him Izzy.

* In {{Bleach}}, Ichigo (Kurosaki), (Orihime) Inoue and (Uryu) Ishida are on a LastNameBasis with one another, including (Yasutora) Sado, though he does call Ichigo by his first name (Ichigo misread "Sado" as "Chad", so that more or less counts). Rukia is on LastNameBasis with the gang except for Ichigo and Renji. Ishida is on LastNameBasis with most everyone (excluding some minor characters), and the only person who refers to ''him'' by his given name in the Japanese version is his father (and later Pesche).

* In PuellaMagiMadokaMagica, 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 [[spoiler: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.

* In ToAruMajutsuNoIndex[=/=]ToAruKagakuNoRailgun: Kaori Kanzaki, Mikoto Misaka, Ruiko Saten, Kazari Uiharu, sometimes Touma Kamijou and a few others.

* 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.

*** He does use honorifics with the upperclassmen, but it's almost always -san and not [[SenpaiKohai -senpai]]; in later novels he starts to refer to Kimidori as "Kimidori-senpai".

* Despite being the OfficialCouple of the ''{{Bakemonogatari}}'' series, Hitagi refers to Koyomi as Araragi-kun, while he calls her Senjogahara-san

* In PuellaMagiMadokaMagica, 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 [[spoiler: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.

* In YuYuHakusho, 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 [[spoiler:his first name changes based on which personality is in control]].

* Almost nonexistent in OnePiece, due to relatively few characters even having last names, but some of Zoro's opponents call him Roronoa.
** Though it can be noted that in OnePiece pirate crew titles function much the same way as last names. Luffy's opponents rarely call him Luffy, or even Monkey (thank god, that would sound ridiculous) but instead tend towards calling him Strawhat. Franky, who started out as a villain and got used to this, still calls him that. Other examples include Whitebeard and Redhair.

Played straight with Rob Lucci, and a few other villains however. Ruthlessly averted with Garp and Roger, both of which always go by their first names, and no titles at all.

* Sakaki and Kagura from ''AzumangaDaioh'' 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.)

* 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.

* Otonashi, Iwasawa, and Naoi from ''LightNovel/AngelBeats!'' are always referred to by their last names, even after their first names are revealed (Yuzuru, Asami, and Ayato, respectively).

* Otonashi, Iwasawa, and Naoi from ''Anime/AngelBeats!'' are always referred to by their last names, even after their first names are revealed (Yuzuru, Asami, and Ayato, respectively).

* Youhei Sunohara of ''{{CLANNAD}}'' usually goes by his last name with the exception of his little sister Mei.
