Haiyoru! Nyaruani

Haiyoru! Nyaruani is a series of animated Flash shorts based on the light novel "Haiyore! Nyaruko-san." The shorts center around Nyarlko, a female anthropomorphism of Nyarlathotep from the Cthulhu Mythos, constantly receiving reprimands from Mahiro, a normal human boy, for her eccentric behavior. Nyarlko's actions often result in chaotic situations, such as drawing a provocative body pillow design featuring Mahiro and herself, prompting Mahiro to threaten her with physical harm. Cthuko, a female anthropomorphism of Cthugha, also appears in various shorts, showcasing her obsessive affection for Nyarlko.
