Ep. 7: Natsume uncovers Matoba Seiji as the youkai blood thief and faces his dangerous ambitions.
Aired on August 16, 2011

Natsume discovers that exorcist Matoba Seiji has been stealing youkai blood. With Natori’s assistance, he investigates but is captured by Matoba’s servant youkai. Matoba reveals his willingness to sacrifice any number of youkai to achieve his goals. He explains that he is gathering blood to break the seal on a powerful youkai. This encounter forces Natsume to realize that some individuals treat youkai in a completely different manner than he or Natori do. The situation highlights the stark contrast between Natsume’s compassionate approach and the ruthless methods employed by those who view youkai merely as tools for their own power and ambitions.
