A Luden is a special type of artificial intelligence. The Ludens are key figures in Death end re;Quest and Death end re;Quest: Code Z.
Death end re;Quest[]
As part of their goals for world conquest, Aphesis Lane sought to create an AI being. To accomplish this, they kidnapped thousands of individuals, taking advantage of the "unused" portions of their brain functions to power a computer network capable of creating a Luden. To utilize outside expertise without alerting others to their actions, Aphesis billed the network as the "Alice Engine", a game engine capable of highly-advanced artificial intelligence.
Aggle, a major corporation secretly ran by Aphesis, would team with small-scale gaming studio Enigma Games to create a Virtual Reality MMORPG named World's Odyssey. The project, headed by bright-eyed designer Shina Ninomiya, was a perfect fit for the Alice Engine. Shina's team, including lead programmer Arata Mizunashi, worked on W.O.D. for two years. Near the end, the project was plagued with difficult and/or outright-impossible to fix bugs. Worse yet, Shina Ninomiya disappeared without a trace. These two issues caused W.O.D to be cancelled.
Shina had actually been kidnapped by Aphesis, who introduced her to the prototype Luden named Iris. Shina and Iris lived in W.O.D for a time, forming a close bond. However, at least six months prior to the events of Death end re;Quest, Shina discovered Aphesis's schemes and was murdered as a result. This caused Iris to become furious and rebel against Aphesis. As part of the rampage, roughly one-third of the kidnapped were rendered brain-dead, leaving four other Ludens in their wake: Alice, Nova, Levin, and Ripuka. Iris' body was destroyed, creating the Entoma, but Aphesis was nonetheless powerless to stop the Ludens from shutting them out of W.O.D.
The Ludens seek to accomplish Iris's goal of visiting Shina's world. To that end, they created a virtual clone of Shina and began testing the boundaries between Shina's world and W.O.D.
Death end re;Quest: Code Z[]
Ludens return in Death end re;Quest: Code Z, in this game they are described as ''spirits'', a person can become a Luden from near-death experiences. Shina Ninomiya turned into a luden due to almost dying in a car crash, which did end up killing her mother.
The Observer ''ARATA MIZUNASHI'' has made several Ludens based on the Death end re;Quest cast with combining several traits from different people and the game data of the World's Odyssey party. These Ludens are named the ''Glitch Girls'' who try to chase after and kill Sayaka Hiwatari when she's going through the Strain Area dungeons.
The game brings back every previous Luden except Ripuka and introduces some other Ludens for example Sayaka Hiwatari is a new adept made partially from Ripuka's data, Basilissa is a Luden who's also part Ripuka. Snark is a Luden who most likely used to be the Entoma Queen named Jeez and Fiend is a ''failed Luden'' which is the result of Lydia Nolan and Julietta Nolan trying to revive themselves as Luden but failing horribly, merging together in the process and becoming some kind of monstrosity.
Traits[]
Unlike the so-called AI characters that make up World's Odyssey, the Ludens are true, autonomous artificial intelligence. Alice, the de-facto leader of the Ludens, manages to write a piece of code in five minutes that Arata speculates would have taken him five days. However, Alice admits that they do not have a complete range of emotions; she encourages Arata and his party to regularly visit her and her peers so that they may learn more in that regard.
While only Ripuka is fought as a boss, it is heavily implied that the Ludens are immensely powerful, especially within the Strain Area of W.O.D.. One Death End has a Luden (heavily implied to be Nova) effortlessly split Lucil Filarete in half. While Ripuka is fought three times, the only time that the party does any meaningful damage to her is after the God of Death intervenes.
The Ludens are aware of worlds that exist outside of the bounds of W.O.D. Their plan to grant Iris's wish involves collecting data on "bugs" (i.e. supernatural phenomena) from Arata's world and using them to manipulate the Primitive Language, forcing a merger between Arata's world and W.O.D. The Ludens are also seemingly aware of the Observers, as Ripuka taunts Arata for trying to behave like one. But perhaps most interesting is that it is heavily implied that the Ludens are aware that the player of Death end re;Quest exists, with "God of Death" being a title that they assigned to them. Alice addresses the God of Death multiple times, the Ripuka DLC having her do so without Arata being around; Ripuka on the other hand is openly hostile toward the God of Death, implying that she wants to kill them and even destroying the game's camera to spite their ability to watch the conflict without consequences.

Trivia[]
- The Ludens are likely based around the ludens from the Noon Universe novel written by Arkady and Boris Strugatsky which in turn is based around the Homo Ludens book by Johann Huizinga, they are described as humanoids who are born human, but possess mental powers beyond the average human. These abilities (referred in the text only as the Third Impulse System) can be activated and developed, a process that takes several years. Ludens view themselves as a distinct race, and claim to have "different interests" from humanity at large, in some instances claiming to be above traditional human morality. The Ludens routinely conduct experiments on humans and alter their minds in order to further their own means.
