Nyanko-sensei as a real teacher might be interesting if you want to learn about sake, desserts and fish.
The last eye catch of the season had Nyanko-sensei do a lazy roll.
Nyanko-sensei doesn't mind Natsume having a cold as long as he shares the snacks.
Natsume had a strange dream where his youkai friends were in his class. And there was Nyanko-sensei Sensei!
There will be two more episodes in the bluray discs before Natsume comes back for another season next year. Nyanko-sensei will have to do a few more turns before going to sleep before then.
