Miku

Miku is somewhat strange and goofy, She loves to use sarcasm but is rather bad at it which leaves most people wondering whether she is really being sarcastic or serious.
Most people end up having to ask her for clarification, which causes her to be embarrassed. She is also a want to be rebel. She loves to pretend like she is a hardcore rebel but really is pretty far from it.
She's a goody two shoes, and can't stand the thought of actually hurting someone else. That doesn't mean that she won't stand up for a cause of friend.  
Icarus is Miku's boyfriend and she absolutely adores him.
Icarus doesn't always show the way he feels, but Miku understands him. She likes hanging out with him, because he makes her life interesting.
He doesn't mind if he doesn't always say what he thinks, because she likes the mystery and knows if he needs to share something she'll be there.
