It was a ball of yarn. It didn’t know why, but it had become conscious. One day, it happened to see a glowing fluffy ball and reached out to touch it with a loose end. A flash of silver light, and it vanished from where it stood.
The System was just taking a break when a sentient ball of yarn unexpectedly bound it.
It never imagined that its first Host in all its years would be a ball of yarn. The other Systems would laugh themselves silly if they found out.
There was nothing to be done. They were bound now, so it could only take its charge… no, its ball of yarn, along to complete missions.
(The System’s mission is to help well-behaved children who are forced to transmigrate, without changing the course of their original worlds.)
One: The Zerg
