i dont get the recent story

My theory = People in suit who said repent etc were the grave visitors who are descendants of Fujiyoshi people (like the Chief), they are actually said repent to bald ghost not to the MC and other grey workers. And the Takaidzu people who talk to our MC are actually real people, they're just hiding from the grave visitors and with help from their ancestors (those creepy ghosts) they kill grave visitors who have Fujiyoshi blood. Current Takaidzu people believe that Fujiyoshi were oppressing their ancestors thus wants to avenge them but the last page reveal that Takaidzu massacred Fujiyoshi ppl.
TL;DR Takaidzu ppl are evil

thanks
