Haiyore! Nyaruko-san

Haiyore! Nyaruko-san is a Manga originally published in Comic Earth Star in 2011. The story revolves around Mahiro Yasaka, a high school boy whose ordinary life takes an unexpected turn when he is pursued by a menacing alien one night. His situation is unexpectedly altered when Nyaruko, a shape-shifting Cthulhu deity of Chaos, manifests as a silver-haired girl and saves him from the pursuing extraterrestrial being. Nyaruko reveals to Mahiro that the creatures from H. P. Lovecraft's works are, in reality, various alien species. She further explains that she has been sent to Earth to protect Mahiro from being kidnapped by an alien trafficker. As a result of their initial encounter, Mahiro's home becomes a makeshift shelter for Nyaruko and two other Lovecraftian beings, Cthugha and Hastur, who have also found themselves stranded on Earth. This peculiar arrangement leads to a series of comedic misadventures as Mahiro becomes embroiled in the lives of these extraterrestrial entities. The convergence of Mahiro's mundane daily life with the presence of these otherworldly beings creates a unique dynamic that sets the stage for a series of unpredictable events.
