Not surprised that the undead aren't hostile either. They don't try to hurt you, they just try to hurt your wallet. Perhaps drag it into the grave, too. Drain your pockets, and soon you'll join em too.
Also wow that's certain a unique party makeup.
Honestly I have to give credit to the author; this is indeed the single most infuriating character I have ever seen in any manga. I really hope the ending is the 'curse' where he dies if he ever leaves her turns out to be false and the first thing he does it books it.
