I shall seek revenge

I was summoned, then I was betrayed and I died...or at least I think I did.  Wait, what?  You're telling me that there was a mistake with the original summoning?!!  So you're going to reincarnate me and I get a second chance with bonus perks??  Well hurry up I haven't got all day!!!  Revenge is a dish best served cold!!  BWHAHAHA!!!
