Natsume arrives at the exorcist meeting to help smoke out the youkai that Matoba wants to find. But he quickly discovers that the situation is more complicated than it first seemed. The youkai is capable of replicating itself to possess targets, and no one but Natsume is able to see who is possessed. Natsume and Nyanko-sensei search the halls, still unsure if they even want to be there.
Stop it, Sensei!
¡Detente, sensei!
Pare com isso, Mestre!
