Sentries

In a world where the Heavens and Hell are feuding non-stop! (Tbh, this is gonna sound a lot like Romeo and Juliet, but I dont care.) Mark and Jack have been assigned as sentries by the big boss of the angels, Marzia, to scout out for invasions. Little did she know, Felix (the big boss of the Devils) had sent Amy and Signe to do the very same thing. But what will happen when these little angels come across the two little devil darlings?
