Pleiadian

Stranded on Earth after her spacecraft suffered a catastrophic breakdown in orbit, this extraterrestrial being from a distant star system devised a plan to recover the scattered engine fragments by bestowing magical abilities upon Subaru and her companions. Disguising herself as a green octopus-like mascot in everyday life, she presides over the group's club activities under the title of 'President.' Unable to communicate directly with humans due to an inherent language barrier, her intentions are consistently relayed through Nanako, who acts as her devoted interpreter.
