One day, Kai was walking down a street when a flower pot fell and hit him in the head.
"What the heck! Who dropped a **** flower pot!" He looked up just to see another one smash into his nose. And he dropped to the ground.
"T-That hurtsh!!" His words were muffled as the ceramic pot filled with soil had broken his nose. Once again, he looked up to see another flower pot-except this one was screaming at him.
"WHY WON'T YOU DIE ALREADY?!" The flower pot fell onto Kai, then another one, and another… Needless to say, he didn't get back up.
—————————————————————————
An unknowable amount of time later, motes of light slowly gathered into an orb.
'WAKE UP'
A voice rang out through the silence. It didn't stop, until everything distorted.
'Good, you have awakened. It's been a while.'
Pain. Like the sound of nails against a chalkboard, but ripping through your mind, tearing chunks out of you. That's the pain that Kai felt when he woke up.
'I can only wait so long. There is a lot to be done.'
Kai again felt the pain, but this time it burned words in his head, the pain used as a way of communication.
"WHATS HAPPENING TO ME?!" Kai shouted out to the void.
'You died, due to a flower pot. Not the best way to die…' The pain was starting to subside, or if Kai was just getting used to it, he didn't know.
"Explain what is going to happen next. And how did that flower pot talk?" The orb of light started to expand, and cracks formed, which shone light out into the void.
'I can answer that and so much more… but you must become my host.'
"What's a 'host' and why do you want me to be one?" Unfortunately Kai never read much, so he didn't understand what a system was.
'If you want to know what a host is, you must know what I am. I am system 00000011 and I need a 'host' to continue existing. In a way, I'm a parasite, but one that brings benefit to you. I in return gain a little energy from you and get to become a more powerful and important system. I needed you specifically because you fit my requirements.'
"Wow, that was a looot of stuff. But I don't think I want a parasite attached to me in any way.." Kai was very suspicious of this 'parasite' who probably caused his death, and ultimately, he just wanted to go home.
'That's fine, but if you reject your soul gets consumed by the void, and you won't enter the wheel of reincarnation.'
"How is this a fair deal?! I get killed by a flower pot, and a parasite is forcing me to accept it or I die permanently?! Fine, I accept your deal."
'Good. You will be sent to [world 125567] and will be reincarnated as grass. I will come with you, but I will lose most of my sentience. Goodbye.'
"Grass?! A new world?! Wait-"
