Everlasting Summer contains many references to various Russian Image Boards:
General image board references:
- Semyon, while a real Russian name, is also Russian image board slang for "same person."
References to IIchan:
- Lena is based on IIchan mascot Unyl-tan (Despair-tan).
- Yulya is based on IIchan mascot YuVAO-tan.
- Olga Dmitrievna is based on IIchan founder and administrator Mod-tan.
- Viola is based on IIchan-created Collider-sama
. - "Bus 410" is an IIchan meme for a bus going to the Hell.
- At the very beginning of the game, on Semyon's computer, his browser displays an IIchan thread. (The thread in question is titled "Stephanie thread." A photo of said character is also clearly visible.)
- The Genda statue is a double shout-out: one part is rather obvious, the other is an infamous IIchan namefag.
References to 2ch:
- Alisa is based on 2ch mascot 2ch-tan.
- Slavya is based on 2ch mascot Slavya-tan.
- Ulyana is based on 2ch mascot USSR-tan. (Also, Ulyanov is a real last name of Vladimir Lenin.)
- Zhenya is based on 2ch-created Mithgirl, a Rule 63 of Mithgol the Webmaster (a rather infamous and bizarre Russian blogger.) His altered portrait can be seen on her cabin's wall.
Other references:
- The character of Miku is styled after the Vocaloid of the same name.
- The first time Semyon hears Lena's name he (being an otaku) mistakenly mishears it as "Rena", complete with a menacing image of said character wielding her iconic cleaver. This doubles as a Foreshadowing for the Miku route.
- The character of Elektronik is named from the main character of a Soviet science fiction miniseries. His cohort Shurik's name similarly comes from a Soviet science fiction film.
- Ulyana and Semyon are watching a film heavily implied to be The Terminator (while doing "Reaction Guys" poses.)
- The achievement for Ulyana's good ending? "Attack on Pedobear".
- During the card tournament, the back of each of the cards has a shot of all the characters together, similar in composition to one in Lucky Star's opening theme.
- Really? One story better than the other. Semyon in your house, Semyon harassing you. Why do you keep lying? That's horrible.
- Many shout outs are given as posters on the walls in cabins:
- Semyon's wall: Fantômas
- Alisa's wall: Detroit Metal City
- Ulyana's wall: A Kitten Named Woof, Stalin vs. Martians
- Miku's wall: Vladimir Vysotsky, Kannagi: Crazy Shrine Maidens, Viktor Tsoi
