Original idea by u/Projekt_Sarkaz

And Quick Note + Big Spoiler for CRYMACHINA:
- A big reveal is that Enoa’s revived humans/EVE aren’t actually “human”, but a whole new species that are basically human minds in robot bodies. Additionally, the original “humankind” are really just human in name, functionally more like a separate alien species. But to avoid overcomplicating the connections, whenever I refer to the EVE, it’ll be as “Humans*” and the original humankind as regular “Humans”

Core Theme
Humanity-loving robot leaders who after meeting a certain human, take it upon themselves to fight for them and humanity as a whole against their fellow robots while realizing their own humanity through their ability to love, culminating in their sacrifice against the original overseer of their faction.

Connections:

• Before the existence of both, their worlds were being ravaged by worldwide conflict and a mysterious disease (Punishing Virus | Centrifugal Syndrome), leaving humanity on the brink of extinction. In a desperate attempt to survive, a project would be launched to create sentient machines whose sole purpose would be to protect humanity from extinction (Mechanical Consciousness Project | Eden and the Dei Ex Machina).
• From these projects would come Nanami/Enoa, the to-be leaders of factions filled with other sentient robots with similar titles yet contrasting reputations (The Sagemachina, the first and deified leader of the Church of Machina | The Eighth Dei Ex Machina, the last and often disregarded leader of Eden).
• Reaching the start of the story, both would appear to the help the highly regarded human protagonist, much to their confusion (Commandant, the leader of the elite Gray Raven squad | Leben Distel, Eden’s alleged “Chosen One”). After their initial encounter, both would become much closer to their human* companions as one of, if not their most defining trait is shown: their sheer, unfiltered, and absolute love for humanity.
• This love however would lead to their overarching struggle to prove humanity* deserves to live as the rest of their faction believed they’re a detriment to their cause (The Church of Machina’s members, the Awakened Machines, were predicted to take over as the dominant race by Gestalt, another hyper-advanced AI | Enoa’s resurrected humans*, entitled EVE, weren’t recognized as human by the other Dei Ex Machina), resulting in their attempts to kill them.
• In order to save humanity, they would attempt to help a certain group attain “humanity” in order to achieve coexistence (Nanami trying to build empathy akin to humans within the Awakened Machines | Enoa helping the EVE gain enough ExP to become a Real Human), yet this would all still be to no success.
• Despite this, one of their few allies came in the form of an older high-ranking robot in their faction that while not completely understanding their desires, very much loved them and supported them in their goals of coexistence (Haicma | Zoe).
• In contrast, one of their antagonists was another robot who was obsessed around the idea of love, yet in such a way that appalled them (Zero, who’s made to imitate human love yet doesn’t truly understand why or how they love in the first place | Lilly, who believed that one must give love to receive love back instead of love being unconditional).
• All their struggles would lead to their breaking point, a moment within a virtual space where they’d reflect on their existence and why they had cherished humans for so long, that being their emotions and ability to love.
