EPISODIUM
Natori invites Natsume on a hot spring trip. But noises from the closet and a kimono-clad figure dangled from the ceiling make Natsume uneasy. Not wanting to trouble Natori because of his kind gesture to enjoy the hot spring with him, Natsume investigates the hot spring himself. During the night, Natsume meets with the Youkai, where she comments that he is too soft, and attacks.
