Natsume is walking home one day when he's accosted by a flying Tengu, who lifts him up into the sky!  Meanwhile, Nyanko-sensei is stuck in a well, where Nanase tells him a story about how she learned to never get close to a youkai.
The evil energy that was 
afflicting him is gone.
Ya había desaparecido la energía 
venenosa cuando la encontré.
Cuando la encontré, ya había sido purificada.
A energia maligna dele já se esvaiu.
