Adaptation of the short story written by Manta Aisora for the first issue of GA Bunko magazine.

It is summer break and Keima intends to spend all his time on video games. An old acquaintance, the timid girl Tenri, comes back into the neighborhood—and apparently has a lost soul inside her. It is up to Keima and Elysia to unravel the secrets of her heart. (Source: ANN)

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.

The story centers around Nyarlko, a formless Cthulhu deity who can take on the shape of anyone it wishes, but particularly the shape of a seemingly ordinary silver-haired girl. Mahiro Yasaka is a normal high school student who is chased by aliens one night, until "Nyarlko" saves him. (Source: ANN)
