- Awesome Music: For an anime that doesn't exist, the tracks selected for the mock Keit-Ai OST sure are some of the catchiest DECO*27 (and otherwise) songs around, which includes:
- Critical Research Failure: In the webcomic version of Keit-Ai, its "P.S. Face to Face" chapter features a data limit surcharge in US dollars instead of Japanese yen even though it's set in Japan.
- Forced Meme: Keit-Ai is an example of one that actually became a meme. It was originally posted over and over on "Write an Anime Plot" threads since 2011 as a Running Gag of sorts reminiscent of "Lolis skateboarding competitively", "Imagine punching somebody so hard that they turn into a door", or "Ghost Slide" (another fake anime concept based on a 4chan in-joke).
- Gratuitous Japanese: The original fiction version of Keit-Ai has a tendency to needlessly add Japanese words, terms, memes, and references to it, often to its detriment (like the way it insists on using "Iincho" instead of the English equivalent of Class Representative).
- Germans Love David Hasselhoff: Or rather, Germans seem to love the Keit-Ai meme the most, as evidenced by these two videos at least.
- Hilarious in Hindsight:
- As pointed out by this Reddit comment in reply to the similarities between Your Name and Keit-Ai, "The strangest thing was that the posters and trailers for that film were actually shopped to make fake 'promotional material', before anyone even knew what the plot of Kimi No Na Wa was about. Then it came out, and the resemblances did not escape the attention of /a/."
- The plot is almost word for word what happens in the Y!Mobile web drama Parallel School Days, made years after the original pasta. The first episode even starts with the female lead confessing to her crush, while said crush in an alternate reality is confessing to her by phone.
- Incredibly Lame Pun:
- For some people, combining the rōmaji versions of the Japanese words of "Keitai" and "Ai" constitutes a groan-inducing pun.
- Ditto for the English equivalent of the title, which is "Cel-Love".
- Irony: Although Keit-Ai was originally conceived as a concept for a "Write an Anime Plot" thread, it has become everything but an anime, jokes about Your Name and troll videos aside.
- Lost in Translation: There are those who'd argue "Keit-Ai" is an impossible pun in Japanese because "携帯" is composed of "Kei" and "Tai" syllables, so there's no place for "愛" or "Ai". Also, there's no such word as "Keit" in Japanese and to render it as "ケイト" or "Keito" would just ruin the original meaning of the intended pun (something about love and phones). This is gotten around by rendering the title as "Keit愛" in art or edits.
- Memetic Mutation:
- As the Keit-Ai Know Your Meme page shows, this copypasta is often modified to reference the latest seasonal anime or popular manga at the time.
- It's also been linked to/claimed to actually be the mega-hit Makoto Shinkai movie, Your Name, to the point of people making Keit-Ai references in edited promo posters and Your Name reviews.
- The copypasta has become so ubiquitous that when you search for the generic term "A boy falls in love with a girl" on Google, the first few search results are all related to Keit-Ai.
- Keit-Ai even found a way◊ to cross the memes by linking itself with the "X finds a way" meme made by 4chan's /a/ board based on a famous line from Jurassic Park.
- Rational Fic: According to an anon on the 4chan Literature Board, the original fiction version of Keit-Ai is an "underrated gem" of rationalfic.
- Woolseyism: It's been suggested by an anon on 4chan's /a/ board to render "Keit愛" (Keit-Ai) in full Japanese text as "毛糸愛" (Keito-Ai). In this instance, "Keito" means "Yarn" and "Ai" (still) means "Love". The Japanese version of the title now involves a pun on cellphones, the Red String of Fate, and love, adding a new layer of meaning into it.
YMMV / Keit-Ai
