Mahiro Yasaka was just an average high school student until he was suddenly attacked by a dangerous monster. However, everything changed when Nyaruko, a silver-haired girl claiming to be Nyarlathotep from H. P. Lovecraft's Cthulhu Mythos, arrived and saved him. She explained that the creature pursuing him was an alien called Nightgaunt, who had planned on abducting and selling Mahiro as a slave. After rescuing him, Nyaruko fell deeply in love with Mahiro and moved into his household despite his discomfort. Alongside her were two other aliens from the fictional universe: Cthuko, an obsessed girl fixated on Nyaruko, and Hasuta, a young boy who could easily be mistaken for a beautiful female. Together, they protected Mahiro from extraterrestrial threats while making his life difficult.
