RAMM ni Haiyoru Nyaruko-san (RAMMに這いよるニャル子さん) is a Japanese music project created for the Haiyore! Nyaruko-san anime franchise. Its identity is tied directly to the series, placing it within Japan’s anison and character-song tradition, where music is developed to support an anime’s story, characters, and overall atmosphere.
Because the project exists around a specific anime property rather than as a standalone pop act, RAMM ni Haiyoru Nyaruko-san is best understood through its franchise context. It reflects a core part of Japanese anime music culture: releases that reinforce character branding, deepen audience engagement, and extend the world of a series through song. As a Japan-based act connected closely to an anime title, it is a clear example of how music, storytelling, and fandom overlap in the anison scene.
