Nyarue is an original character created exclusively for the anime *Haiyoru! Nyaruani: Remember My Mr. Lovecraft*, absent from the franchise's original light novels. She shares the same extraterrestrial heritage as Nyaruko, hailing from the planet Nyarlathotep, yet exists as a distinct entity within their alien race. Visually, she mirrors Nyaruko with silver hair and antenna-like features, but is consistently outfitted in an orange sweater.

Her background identifies her as a former classmate of Nyaruko from their shared time in "Space Kindergarten." Nyarue's personality is gentle and marked by significant social anxiety, which frequently causes overwhelming embarrassment or confusion. This intense emotional state often triggers involuntary transformations into her true eldritch form. Her immediate infatuation upon meeting Mahiro Yasaka provokes one such shapeshifting episode. Her anxiety-driven transformations recur in other stressful situations, like when explaining unconventional actions such as relocating a bathroom to a city center – an act she justifies as protecting Mahiro from Night-gaunts or avoiding her makeup-free reflection.

Nyarue's interactions consistently focus on her romantic interest in Mahiro Yasaka. This quieter affection contrasts sharply with Nyaruko's aggressive pursuit, introducing emotional complexity to the group dynamic. Her documented narrative arc remains confined to these core traits and scenarios within this series, with no appearances in other seasons, films, or spin-offs.
