You & the sky

Junsei Egao, a boy living a normal life which fails to satisfy him. He spends most of his time alone. And when he's alone, his mind, or what he calls, the other "Junsei", that inner existence that keeps asking questions and ruining his life. That thing that questions everything. His life. Life itself. God. The world. "Why am I here?" "Is there a god?" "Who rules here?" "Why do I care so much?" "Why does it hurt so much?"
"Why?"
And thus he spent his life. Wondering why. Until that incident. When that group answered the questions he didn't want answered. When the rulers emerged. When his life changed completely.
