Zashiki-warashi
While spending the night in a traditional inn, the Medicine
Seller stumbles upon a strange phenomenon. A pregnant woman who is
desperately seeking shelter at the inn is led to a strange room
upstairs. There, she is attacked by an assassin, who is then
mysteriously and gruesomely killed. A group of Zashiki Warashi are
haunting the room the pregnant Shino is sleeping in. They dispose
of the assassin when he tries to kill her. Apparently, the inn used
to be a brothel.
Back then, the inn's owner routinely aborted her worker's
children so the girls could keep working. The unborn were then
encased in small hollow dolls and kept in the ceiling, trapping
their souls. The unborn are drawn to Shino because of her
determination to save her own child and decide they'd like her to
be their mother. After saving her, they cause a bunch of weird
events which drag the Medicine Seller into the middle of the whole
affair.
The Zashiki Warashi want Shino to give birth to them, and she
agrees (to the Medicine Seller's dismay). She pulls a sutra off her
stomach (after taking a beating from the inn's owner who was trying
to abort her baby) and ends up seemingly miscarrying her infant
five months into the pregnancy.
At the end of the episode, the Medicine Seller seems to have
saved Both Shino and her child since she is seen with a big belly,
knocked out on the floor. However, some speculate that the final
scene after the ending credits implies that the child she is about
to give birth to is in fact the Mononoke, having taken the place of
her own miscarried child.
