[Draft in progress]
Worlds are always beset by disaster.
Worlds always need humans to step in and save them.
Worlds can always be brought back from the brink by humans after countless perils.
Their higher-ups never installed self-rescue functions, so the worlds can only act like weak princesses, helpless against dragons, nervously shouting "666" for the humans playing heroes.
Humans carry the team, worlds coast to victory. As long as there are humans, the worlds won't be destroyed, except for the unlucky worlds whose endings are destined to be bad.
F0865 had been relieved that it wasn't one of those unlucky worlds and wouldn't have to watch itself steadily approach destruction.
But when it secretly peeked at its future timeline, it discovered...
Its humans were gone.
F0865: ...What the hell?
With all the heroes dead, no one could slay the dragon, so the princess got eaten and the game ended.
F0865 decided that this was unacceptable, and gritted its teeth as it made the most important decision of its entire life.
It would save humanity.
Before the humans managed to get themselves killed, it would infiltrate the lives of important people closely tied to the world's fate and personally help them reach their happy endings, so that humanity could survive safely to the very end.
So one day, its rescue targets heard the world roar:
"All of you, clear the game perfectly without a scratch and come save your daddy, you human idiots!!"
1. No romance, beloved by all. F0865 is merely a short-tempered, emotionless happy-ending machine. It doesn't want to date its boys.
2. Lighthearted and cheerful, lots of personal worldbuilding, indulgent wish fulfillment, logic be damned, severe OOC warning.
3. To be added.
Theme: Sincerity can move the world
