Give it up.
You think you have an amazing idea, but you really don't... Every teenager on the planet thinks they have a brilliant idea for a comic, anime, tv show, band, whatever... but how many teenagers make it onto Hollywood payrolls?
Ideas aren't enough. People aren't paid for their fantasies: they're paid for their abilities. If you REALLY want your idea to see the light of day: you'll need to bring it to light yourself. That means you need to go to art school, film school, take writing courses, draw a webcomic/manga yourself, go to school for animation/game design, whatever.
No one pays people to "come up with good ideas"... they pay people to make those good ideas into something worthwhile.
Do it yourself or it isn't going to happen.
