Bro of a Bitch

I've seen self inserts of Shield Hero before. But none of them had the mc reincarnated as The Bitch's twin brother. For me, this is reality, and it sucks. I have to deal with a petty grudge she has against me, the great expectations that come with being royalty, and being on the shit list of several people, including Naofumi.
It's not all bad though. I'm not dead, I have the spirit of a phoenix inside me, and I have knowledge of the Anime on my side. So, here goes nothing, time to go fix things.
