Kayden got into a fight bigger than himself.
He was fatally wounded but survived and won so that's fine, highfives himself.
Urrgh he's puking up blood and bleeding out simultaneously. The situation struck him kinda funny he was laughing as he crawls to wherever.
Delirious and snickering to himself, that's how Kartein found him.
(At that time both Kayden and Kartein have no idea about awakeners, they kinda just know something's different about them and roll with it cause like?? So I can electrocute people, what now? So I can heal people, what now? Anyway..)
Recently some weird people came to Kartein's town and were rampaging there. He's actually on his way to move out, cause gosh darn he can't take it anymore.
ANYWAY, he found Kayden sprawled on the bushes chuckling despite being half dead.
He figures, oh another one of my townsfolk who fell victim to those.. whatever they are.
Nudges him with his foot, arrgh blood on my shoe hey you alive?
Kayden's mumbling snorting incoherently.
Kartein sighs and thought, fine fine.. this is the last time I'll be doing this for you people I'm fucking 12, yall gonna kill me at this rate I already feel anemic.
Heals Kayden just enough that none of his bones are protruding crudely nor is he leaking blood everywhere. Okay, my job here is done.
Kayden gains some bearings before Kartein could leave. Yo, what's going on here?
Kartein's like, some dudes are blowing up the town so I'm leaving. What about you? Did you get caught while leaving too? I found you here, anyway try not to die again.
Oh, okay.. thanks. Are we friends?
Heck no?! Where did that come from I even helped you you ungrateful little-
Oh sorry, sorry. My brain's fog is all. I can't seem to recall anything, heck I can't even recall my name.
Kartein watches him, yeah your name's Buttercup.
Kayden clicks his tongue, so my name's Buttercup.. I was better off not remembering uurgh why did you tell me..
And Kayden went by Buttercup for most of his teen years until he fought some gentleman awakener who on the verge of death went all, I shall know the name of the noble lad who bested me
Kayden's like, yeah sure I'm Buttercup
And the gentleman awakener died laughing, that's when Kayden decided okay Buttercup can't be his name
Fast forward to when Kayden calls Kartein to ask him to help his student, hey dude it's me.. Buttercup
And Kartein decided to help him at the time just to make it up to him for making him live as Buttercup all those years.
