Very interesting. I'm generally not a big fan of AU fics, but I can really see Wolfwood in this role. And Vash as the young cop out to prove himself works, too, though maybe to a slightly lesser extent. Maybe later chapters can show us some of the strength and skill we've come to expect from our favorite soft-hearted cuddly blonde. ^_^
I'm curious who Picasso is going to turn out to be, if anyone--Legato? Knives? Looking forward to more!
