Second Chance Reincarnation

I lived in poverty with my little sister, robbing and pick-pocketing people just for us to get by. But in a turn of events, we get robbed and died by gunshot. I got reincarnated into some magic world with an annoyance in my head. An egotistical, self-absorbed chuunibyou of a Goddess living rent-free in my mind. I am on a mission to search for my sister and answers in this New World. But will I be able to do that without making enemies along the way? Abandon your horrible upbringing, embrace change and protect what you love. I am Polyphormes Raijin, The Magus Archer of The Raijins. And this is my second chance at life.
