Let’s just talk about the ending and skip the rest of the show. Well to be honest nothing much happened till the last few minutes where Natsume suddenly makes up his mind to tell Natori about the Yuujinchou.
The rest of the episode goes something like this. A famous exorcist dies leaving all his grand and worthy work behind but the thing is no one can find it. The place he used to live is a mansion and every room’s been searched but nothing came up. So the granddaughter who is bitter by the lack of love and attention from her grandpa opens the house to the exorcists and whoever can find the data can have it. Natsume and Natori visit the mansion. Natsume wishes to find some answers about the Yuujinchou, Reiko and Natori’s lizard mark and Natori’s more than happy to find the research. Matoba’s people are there too and they plan on buying the mansion.
As usual, a yokai hears about Natsume, being the grandson of Reiko and possessing the Yuujinchou, attacks him. Nyanko saves Natsume and Natori hear everything but pretends he didn’t. After thinking Natsume decides it’s time to tell an exorcist about the Yuujinchou.
I don’t know if it’s a good move or not. Maybe Natori’s trying to protect Natsume as we know the Yuujinchou attracts many unwanted yokais and Natori just wants Natsume to live a peaceful life BUT Yuujinchou belongs to Natsume’s grandma and it’s full of names of yokais giving it to anyone would be…
I don’t know anything anymore. I do know one thing, I’ll be really sad if Natori is revealed to be the bad guy.
