Is the blond guy a reincarnation of the first blond guy that died?

It's still him...he didn't die...because he can't? Or cause the shinigami said his name which is more or less a chant of longevity...probably...

Whoops...did you mean the lazybum blond guy and the blond host? Nope...

I don't think so coz when he got the croquet he said you are the second person in my life to give me anything. He got fish from the lazy bum.

Maybe yes, maybe no ... it's pretty vague :-/ there seems no connection between these two. And @Nogisu, no, the translation is "this is the only second time someone has given me something" ... "Second time", not second person. So there is a possibility that they're just the same person.
