The trio are Kagome Higurashi's present day school friends who seem to be quite nosy when it comes to her personal life. They are always nudging Kagome to make advances on Hojo, a popular school boy who obviously admires her. And when they first hear about InuYasha, they constantly encourage her to drop him due to her seemly bizarre descriptions of him; However, in later episodes Kagome's three classmates begin to like "Mr. Possessive." In episode 160 entitled "The Lucky But Two-Timing Scoundrel!" the girls finally meet InuYasha and find his exotic appearance intriguing, officially approving of him which makes Kagome considerably happy. Eri is the one with the shoulder length black hair who is all about Kagome's relationship health. She never fails to bring up Kagome's potential boyfriends (Inuyasha and Hojo) and isn't afraid to give her full opinion of them. In the episodes that are shown Eri is seen tapping her foot or fingernails and some fans have said that this is a habit of her being wary of someone (usually Kagome). (Source: Inuyasha Wikia)
