Holy crap, yeah, that is kind of a good comparison for their dynamic.

OS-tan Talk / Re: OS-tan hot takes
Last post by stewartsage - Yesterday at 11:01:06 PMYeah, it's another take on the idea of humanizing computing related things, which is cool and all. Not really OS-tan related, other than perhaps he took inspiration from OS-tans.

Last post by Bella - Yesterday at 09:29:33 PMQuote from: stewartsage on June 16, 2026, 09:24:09 PMENIAC/IAS is doomed because ENIAC can't get past her loathing and IAS-sama can't find it in herself to like her. Respect her, maybe, but not like her.
BRLESC-tan should win. Gyaru.
ENIAC/Colossus should also win. They're both still kind of alive, they can make it happen.
They can totally make it happen. I believe.
I'm curious what IAS-tan's feelings are toward ENIAC-heika!

Last post by Bella - Yesterday at 09:23:57 PMI wonder if Goujer-sama might be able to provide insights, I think she's researched more of the in-joke / lore aspects of some of futaba characters than I have.

OS-tan Talk / Where does "koshi koshi an an"...
Last post by oobabasama - June 23, 2026, 01:47:30 PMOne term I've seen quite consistently used in relation to Ōbabasama/3.1-tan is "koshian" "koshi an an" "koshi koshi an an" or variants thereof. The earliest usage of it I've been able to find dates to October 6, 2007 on Pixiv. For quite some time, I've been researching the origin of this phrase and why people have, for at least 18 years, so consistently used it in relation to her but have been unable to conclude an actual origin. Nobody in the Western fandom speaks of it, somewhat consistently with 3.1-tan who despite being by far the most popular OS-tan in the Eastern fandom is a lot less popular in the West, but it's quite inseperable from her in the Eastern fandom, even the body pillow of her I sleep with at night has "Koshi Koshi An AN" printed on one side.
Three candidates I've considered for the origin are;
-The food koshian, smooth red bean paste. It could easily explain it especially considering the nature of Futaba's userbase, but especially given not even one of the posts I've seen using the term have referred to it as a food, I find it somewhat unlikely.
-A doujin that used the term in its title. This was quite easily disproven as the term's recordable usage dates back to October of 2007 which predates the doujin which was published in May 2011.
-An onomatopoeia which I find most likely. "Koshi koshi" is a softer alternative (?) to "goshi goshi" and "an" I believe is the sound of a gasp. This wouldn't explain it being used specifically in relation to Ōbabasama and not with any other OS-tan, but it's the closest thing I have to an origin.
I think it'll be quite hard to actually /prove/ where the term came from because Futaba threads, as with any other imageboard, have preyty much zero permanence, making it hard to trace as with many details of the individual -tan's origins (for example, IIRC there's no details known about 2k-tan's creation aside from her being a collaborative creation as with practically every other OS-tan).
Regardless, many people on this site have been in the fandom far longer than I have, and as such any anecdotes of its usage back then would help.

OS-tan Talk / Re: OS-tan hot takes
Last post by Lily1027 - June 23, 2026, 12:41:54 PMAnd another hot take of mine is, I hate when people says the Merryweather Internet Explorer-tan (and other characters from this series and the whole series) are OS-tans. Those are two separate universes, I mean, I don't mind crossovers or AUs or anythings like that. But I mean it when the context is meant to educate about OS-tans (like wiki or video). It really feels like the person who made it just went to google, found the first image, and told themself "it's humanized ..... so it's OS-tan" and started to find informations about the character even though it's not OS-tan.
I feel like it actually wasn't been never called officially OS-tan comic or anything. But as i've mentioned before, some people just sees something humanized related to technology and immediatelly goes "it's OS-tan".

OS-tan Talk / Re: OS-tan hot takes
Last post by Lily1027 - June 23, 2026, 12:31:43 PMQuote from: Bella on June 23, 2026, 09:39:07 AMMy hot take is not all software personifications are OS-tans but the Madobe are.
I don't know where I draw the line between something being an OS-tan and a non -tan personification, but I think it probably ties into a cute anime girl/boy/person aesthetic, adopting the conventions of the original futaba OS-tans (being a moe anthropomorphism, and memory relating to hunger and breast size for example).
If someone has a 100% original software personification lineup, with its own separate world building & conventions from the original futaba OS-tans, I don't think I would consider those -tan, but personification.
I agree! I don't really mind when someone calls for example: Madobe Nanami an OS-tan but what kinda makes me sick is when someone makes some random cartoonish like OC that doesn't really looks like it fits in the OS-tan genre and calls it an OS-tan.
Most people thinks that OS-tan simply just means Humanized Windows. But I honestly thinks that would be much better if those people would rather use the term Humanized Windows than OS-tan if their OC doesn't really fit the OS-tan genre.
I think OS-tans are meant to be anime humanization of OSes (and sometimes programs etc.), not everything that is just a humanization of OSes.
Kinda surprised how many people's hot takes are the same as mine.
