Back then, Natsume remembers that the youkai was much more smaller, thus he was able to resist the push.

However, later when Natsume visited the Aoi family, he noticed that the youkai getting much more bigger than he used to remember.

Nyanko-sensei informed that it was fine to leave the bug-eating youkai for at least 2-3 years, until it will consume the residence in house.

Knowing the fact, the terrified Natsume lured the youkai away from the house. Both he and Nyanko-sensei ran away from the chasing youkai. When they managed to escape and resting by the river, the youkai suddenly came and possessed Natsume.
