I Chose To Have A System

So I died. Awesome. Worst day of my life. Fifteen years old, and dead. It wasn't all bad though because a goddess came to me, and told me I'd been chosen for reincarnation. She gave me a choice. Be reincarnated as whatever I want or get one of those systems that manga, and anime made so popular. I chose the system. It didn't matter what I was reincarnated as. As long as I had a system I could get strong enough to beat anyone.
