Higurashi When They Cry[]


""How was it? Find a treasure trove?"
"Oh, yes~ So listen! Ah ...um, you see! There was...! A Colonel Sanders doll!♪"
"A Colonel Sanders doll!? ...Oh, that thing. Those statues they always have out in front of that fried chicken place...That life-sized dummy?"
Keiichi asks Rena about what she found at the junkyard, Day 2

Colonel Sanders is the founder and mascot of the Kentucky Fried Chicken (KFC) restaurant chain. Various adaptations and console ports change Sanders' name to either Kenta or Randy, with the KFC name changed to similar acronyms if shown.

"Everyone, listen! Rena's in big trouble! All of you, please look for Rena!"
"...It's a bigger problem than a jumbo jet crashing into your family's house?"
...Oh, yeah, it had turned into that, hadn't it. Mion whistled nonchalantly, trying to avoid the blame.
"Yeah! It's not even in the same league as jumbo jets! What fell on Rena's house...Was a space colony!!"
"A-A space colonyyyyy!?"
"Yeah, it's a really big disaster! Everything in a 100 kilometer radius was obliterated! But that's only the prelude to this tragic tale!! This is the beginning... the start of a war for independence by the Propagandapality of Zeon!!
— Keiichi tries to trick Rena during a game of zombie tag.

This is a reference to the anime Mobile Suit Gundam, which is known for featuring colony drops (space colonies hijacked and made to plummet onto Earth's surface) committed by the antagonists, the Principality of Zeon.

"...That's the principal's aerial opener!"

"From how it sounded... the principal's jumping fierce sounds like a multi-hit combo."


"PrincipaaaAaaAal!!! I challenge you...hurRrk!!!!!!"
I heard what sounded like a "zhazhing" three times. His 3-gauge super!?
— The club tries to do punishments involving the school principal.

A reference to Street Fighter II, which released in 1991 and is known for introducing the combo attack mechanic that would become a mainstay of fighting games. The updated rerelease Super Street Fighter II Turbo would introduce the super meter/gauge.


"...'Card Master Sakura' is written down here."(...)"Sa--Sa-Sa--Sa-kura can only mean 'Card Master Sakura,' can't it!?!? It's a super-popular anime that's broadcast every week on the government-run networks!!!" (...) "...Um yeah, even without the forced explanation, I know about it. It's that thingy where she fights in a different costume every week, right? Yeah. I know, I know." (...) "I saw it for the first time recently. Sakura is cool and so cheerful all the time!" "...I like that girl who's always filming with the camcorder." (...) "Sakura means Sakura Kinomoto!! Sakura-tan *pant pant*!! Card Master Sakura is the right answeeeeeeeeeeeer!!!"

A reference to the series Cardcaptor Sakura, which began in 1996. It stars a girl named Sakura Kinomoto who fights evil and wears various outfits while doing it. The character Tomoyo Daidouji follows Sakura and records her battles with a camera.

Legend of the Golden Witch[]

"......I haven't told anyone, but when I was in kindergarten, I joined up with a little gang of kids trying to form an Earth Defense Force, saying we'd help protect peace on earth. My face turns red when I remember how, during what we called battle practice, we would chant `EDF! EDF!'..."

A reference to the Earth Defense Force video game series, of which Ryukishi is a fan.[1]

Turn of the Golden Witch[]

"Didn't I say they should pass the time as they pleased?!! They can sing if they want, dance if they want! They're even free to hang themselves by the neck or jump into a boiling kettle!! Until 13 people die, they can spend their time as they like. If that's too boring, then they can wonder about whether 6x9=42, or something!! That's the answer to the mystery of humanity and the universe!!"
Kinzo rambling to Shannon, Chapter 11: New Rule

A reference to the book The Hitchhiker's Guide to the Galaxy.

Banquet of the Golden Witch[]
