Animated Flash shorts based on the light novel series "Haiyore! Nyaruko-san." In these shorts, Nyarlko, an anthropomorphized female version of Nyarlathotep from the Cthulhu Mythos, is constantly being told off by Mahiro, a normal human boy, for all the crazy or stupid things she does. In one of the shorts, Nyarlko is drawing a cover design for a body pillow. It turns out that the pillow's subject is a half-dressed Mahiro in what appears to be a hot and heavy scene with Nyarlko. Naturally, Mahiro proceeds to stab Nyarlko in the hand with a fork and threatens to kill her if she releases the pillow design. Other shorts revolve around various gags and occasionally feature Cthuko, an anthropomorphized female version of Cthugha, who's madly in love with Nyarlko.

In the year of Tenpo 14, Yoi, monsters from another world attack Edo. Those who fight against them are members of Bansha Aratemesho. In public, Bansha Aratemsho is known as an organization to study foreign books. In fact, they are a organization dedicated to destroying the Yoi. These warriors are called Ayakashi. They gather information of odd events in the country, and are sent to destroy Yoi who appear. They are generally very strange people. For example, a guy who has lost his memory, a girl who dresses like a man. They have special powers with which to beat the Yoi. (Source: AniDB)
