Neo Eon

"'It was at that moment that a Neo Eon irreversibly, irreparably, began.'"-Eon and Multis on the start of the Neo Eon.

The Neo Eon is a time period often referred to during the events of One Neo Eon. Curiously, its definition is different from character to character, so it represents more of a subjective philosophical concept that can be best likened to an "ideal world" than any concrete time period.

Virgil's Interpretation
Virgil proposes the idea of the Neo Eon to be a state in which AI and Humans coexist. In his words from Chapter 1, "(Eon) will bring about a Neo age of Machine-Human coexistence! And this age shall last an eon!" It can be noted that Virgil does not specify that the Neo Eon is limited to the actions of Eon, he believes that this movement must be widespread.

Eon's Interpretation
Eon's interpretation is very similar to Virgil's with the additional clause of wanting to be equal to humans. He plans to do this once he is able to create. While Eon seems to act on the belief that the Neo Eon is dependant on him, in his dream sequence, it is revealed that the god of the world believes that Eon's desire is for the Neo Eon to become widespread to all robots. Alternatively, it can be argued that by virtue of existing as an AI, Eon believes that he has already heralded the Neo Eon, as evidenced by the fact he tells Multis in the prologue that he thinks the Neo Eon started the moment he was activated. However, given that the prologue is a within an overly simplistic dream sequence, it can be extrapolated that this is simply Eon not challenging himself cognitively.

From the phrase "(...) a Neo Eon irreversibly, irreparably began", it is implied he and Multis regret their actions.

Multis' Interpretation
In the Prologue, Multis argues against Eon's interpretation of the Neo Eon, saying it started when she met him. This implies that Multis believes that the Neo Eon is the age in which AI will strive to become more than their nature. From the phrase "(...) a Neo Eon irreversibly, irreparably began", it is implied she and Eon regret their actions.

Yamoto's Faction's Interpretation
Yamoto and Yamoto's Faction believe that the Neo Eon will begin once Unintentional Creation doesn't exist. They plan to do this by making Eon the god of the world. Technically, by their interpretation, the Neo Eon has already arrived without them knowing.

The Robotics Club's Interpretation
Similar to Eon's interpretation, the Robotics Club believes that the Neo Eon will be achieved when Eon can create, although they seem to hold the belief that it must be widespread, similar to Virgil.

Yumiko's Interpretation
When Yumiko is about to die, she comforts Eon by saying that her actions may inspire the Neo Eon. This may align her beliefs with Yamoto's Faction, although she also seems to believe in a more benevolent vision, implying that she believes the Neo Eon will become widespread once Eon reaches the emotional maturity to spread his message.

Sakura Edo's Interpretation
Sakura Edo has jokingly conflated the Neo Eon with an Anarcho-Marxist techtopia.

Ningen 108's Interpretation
Although not outright stated, it is implied that Ningen 108 believes that the Neo Eon should be averted until a perfect enough AI is created. They do not believe this to be Eon.
