The FN P90 is pretty cute.

I'm much less critical of Sword Art Online than you might assume, considering how long I've been blogging about anime, so I can understand if readers who loathe SAO are skeptical when I claim Sword Art Online Alternative: Gun Gale Online is a fine series which stands on its own and doesn't have any of the Sword Art Online baggage that inspires the most criticism. For example, there's no Kirito in SAO ALT: GGO. (SAOALTGGO? SAOALT:GGO? Whatever.) In fact, there are no returning characters as far as I can see (there was a Zekken namedrop in the most recent episode, but with no context or elaboration).

Most people don't realize Pink Camouflage Pattern was a
leading contender before narrowly losing to UCP in 2004.

Instead, Gun Gale Online is a reasonably fun low-stakes anime about girls being goofballs at a gun-themed video game with characters who all clearly understand it's just a video game. Well, at least through six episodes. I've probably jinxed it now. In any case, I think the first episode provides a good indication as to what the show is like so far, and is at least worth checking out if you're still on the fence about it. It's different enough that anime fans who hate Sword Art Online can probably enjoy GGO for what it is. On the other hand, I suppose this means I'm not sure anime fans who love SAO will also enjoy GGO—maybe if the rest of the anime suddenly flips from "video game guns don't kill people" to "nutjobs who play video games kill people" or something like that. Since this is an anime adaption of light novels (written by the Kino's Journey author, not the Sword Art Online author), spoilers are obviously available for the harvesting, but I'd rather discover the answer to this question in due time the slow way.

It's because its blocky shape makes it easier to embrace than other guns.

I guess this is a follow up to my recent post, "In praise of the oldest star in Gunslinger Girl." There, I linked to a couple pictures of anime characters hugging their FN P90 submachine guns (Iriya from Iriya no Sora, UFO no Natsu, and LLENN from Sword Art Online Alternative: Gun Gale Online). Naturally, Henrietta also does this in the first episode of Gunslinger Girl, as depicted above, after going aggro with it against some chumps who totally had it coming, probably.

Rounds in the translucent magazine make a 90-degree turn before entering the chamber.

I believe Henrietta's P90 is the most modern firearm to appear in Gunslinger Girl. It was only about 10 years old when the manga began in 2002, and is quite a contrast to Triela's 19th-century shotgun. Its distinctive appearance probably also accounts for its popularity in various anime, Sword Art Online Alternative Gun Gale Online being a notable example. I can't rule out the possibility that some LLENN fan bought herself an FN PS90, cut down the barrel after getting an NFA tax stamp, and painted it pink for questionable cosplay purposes.

This was a pretty good deal for both parties.

Incidentally, I was somewhat surprised a minor character in SAO GGO carried an AR57, which is basically an AR-15 upper designed to accept P90 magazines on top and eject out what is usually the magazine well of the lower receiver. But I'm most impressed that Kirito never showed up in GGO for some bullshit ammo exchange contrivance, since Kirito's FN Five-seveN is pretty much the only other firearm that shares ammo with LLENN's dear P-chan. Kirito's total absence definitely improved Gun Gale Online as an anime.
