killer king
basically what the summary says but, basically, after Kageyama is abandoned on the court, his mind essentially breaks and he becomes something of a psychopath. he vows to get revenge on the people who hurt him (mainly kitadai people in my mind). you can decide if he plays volleyball or not, and how many he dates but much like the song, killer queen by mad tsai, they'll probably wind up dead. also if you want to come up with reasons for him to kill others you can.
what this looks like in my mind:
psychopathic!manipulative!kageyama ( you can decide if he's cold, acts innocent, etc.)
AU
kageyama is actually smart
dark backstory for kageyama before being abandoned
kitadai is the last straw
kageyama x multiple (most ending up dead at his hands)
dark evil kageyama
remorseless kageyama
you can decide if others find out and their reactions
it's up to you if he has and endgame ship or not
will he get away with it? will he be arrested? killed? that's all for you to decide.
if you do write this one or see something similar, please do share, because i'd actually love to read something like this.
for those wondering why I don't just write it myself, I have a bad habit of starting stories and never finishing them. also I don't think I can do these storylines justice.
