Shout Outs in Higurashi: When They Cry.
Anime & Manga
- To Studio Deen's own Maria Watches Over Us franchise in Rei, where Rena fantasizes about herself and Miyo re-enacting the scene where Sachiko fixes Yumi's scarf.
- The sound novels have a few as well. During Onikakushi-hen, Keiichi gives a Rousing Speech with references to both Mobile Suit Gundam and Space Battleship Yamato.
- In the final episode of Rei, one of the mahjong books found in Rena's VW Van is about Washizu mahjong
- When Keiichi and his friends are playing zombie tag, this conversation occurs."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!!"
- When Keiichi decks his dad for ogling at an underage waitress, his dad says "Not even my own father hit me", which is what Amuro Ray said to Bright Noa in Mobile Suit Gundam after he hits him.
- In Watanagashi, Keiichi answers with Cardcaptor Sakura while playing Sympathy with Mion's Club.
- In Chapter 2 Episode 3, during the curry cook-off, Keiichi and Rika play pretend with drawings. Rika states that Mr. Curry shoots missiles from his stomach, and Keiichi responds by blocking it with his his "Super-electromagnetic" (chou-denji) barrier. This is a reference to Choudenji Machine Combattler V, where the titular robot yells "Chou-denji X" before performing a move.
- Either a translation error or a Shout-Out to translation error by Manga Gamer: The miracle never happen.
- At the beginning of Gou episode 2, the scene of Rika meeting Hanyū while lying on the ground in the alternate plane is a major reference to Fate/stay night with the iconic scene when Shirou meets Saber after accidentally summoning her.
- Rena and Ryukishi07's pen name is named after Lenna Tycoon from Final Fantasy V and the Dragoon job.
- Street Fighter II is referenced here:"Principaaaaaaaal!!! I challenge you...hurRrk!!!!!!"I heard what sounded like a "zhazhing" three times. His 3-gauge super!?"
Other
