Synopsis
The story of ''Haiyore! Nyaruko-san'' centers around Nyaruko, a formless Lovecraftian deity of chaos (Nyarlathotep) who can take on the shape of a seemingly cute silver-haired girl. Mahiro Yasaka is a normal high school boy who is being chased by a fearsome black alien one night, until Nyaruko saves him. She explains that the creatures from H. P. Lovecraft's works are actually races of aliens, and that she has been sent to Earth by the Space Defense Agency to protect him from being kidnapped by an alien trafficker. Aliens find Mahiro and the Earth strangely attractive, for entertainment, auction, or resources. One by one, the Great Old Ones land on Earth illegally. Eventually, Nyaruko and two other Lovecraftian creatures, Cthugha and Hastur, end up being freeloaders at Mahiro's place. Mahiro has become accustomed to his protection detail of Nyarlathotep (Nyaruko), Cthugha, and Hastur making his life fascinating.

Reception
The series has received mixed reviews. Aiden Foote from THEM Anime Reviews gave the first season (Nyarko-san: Another Crawling Chaos) a 3 out of 5 stars rating. In his review, Foote says that the anime "should have been a whole better [sic] and could well have been" citing the over-pandering as an issue. He went on to say that a character as well-liked as Nyaruko deserved more when it came to a love interest.
