Time of Eve (ONA)

The Three Laws of Robotics stated in the anime was developed by the famed science fiction author Isaac Asimov.

At the beginning of Episode 3, Sammy comes into the room as Naoko is watching television. When Naoko turns around to ask the android a question, a scene from 'Pale Cocoon', one of Yasuhiro Yoshiura's earlier works, is visible on the screen behind her.

Immediately prior to the main title frame there is a simulated boot sequence that appears momentarily. It reads as follows (// indicates line breaks): Are you enjoying the time of EVE? 028 (tm) Version 1.10.08.01 // (c)2008 Studio - Rikka All rights reserved. // Scanning EVE drives....... // No drive attached to Code:LIFE, The BIOS is not installed.

The title "Time of Eve" is a reference to the 1998 OVA, "Yokohama Kaidashi Kikou", that has similar themes. During the end credits the main character, a gynoid called Alpha who runs a cafe, narrates the following: "The festival-like world had settled to a leisurely pace. To think that an era came to its twilight so pleasantly. The dangerous times have since been called the 'Time of Evening Calm'".

Early in episode 1 Naoko is channel surfing on the family TV. One of the TV stations is TV Rikka. Studio Rikka is the anime company that produced Eve no Jikan.

In Episode 2, one of the patrons of Eve no Jikan calls Rikuo's friend, Masaki, a "Blade Runner". This is a reference to the 1982 cult film Blade Runner, where special police called "blade runners" detect and hunt down artificial humans called "replicants". The patron is alluding to the fact that Masaki was clearly trying to figure out whether the patron was human or android.

In episode 4, Rikuo describes the "Nameless" robot as an LUH model. LUH3417 is a character from the George Lucas science fiction movie THX1138, a film with android police. At the end of episode 4, a close-up of the electronic notice board reveals the number 1138 displayed in columns and rows.

Continuing on the THX1138 theme, in episode 6 the Masaki house robot, Tex, is described as a THX model while Setoro enigmatically describes Time of Eve's rule as #1138

In episode 6, during the anti-robot society's meeting, a card with data on one of the androids that will be performing the investigation into grey zones is shown. The CPU brand is given as "R.U.R". This is a reference to the 1921 play "R.U.R. (Rossum's Universal Robots)" by Karel Čapek. This play is the origin of the word 'robot'.
