I know who the ghost is.......Its the "dead" twin sister... she faked her own death becuase she was pissed off at the people that killed her dad....which are all the people she is killing.. tada
maybe, or its just a stupid ninja(thats use illusion technique)thats was hire by someone to scary everyone

I hope in the next episode that Scooby doo and the gang some how show up in Ninja form to help them hunt the ghost....or if they somehow made a scooby doo refrence.. iut would be almost kinda funny.. yet at the same time it would suck...
ohh? i hate scooby doo, so i wish it happen and naruto rasengan thats stupid dog


^^ thats part made me smile
