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 is purified in this 
well and returns to nature.
Los youkais malvados se purifican en el 
fondo del pozo y ellos vuelven al mundo natural.
Este pozo purifica todo mal y hace que regresen a la naturaleza.
A energia deles é purificada neste poço e retorna à natureza.
