Eri is one of Kagome Higurashi's best friends along with Yuka and Ayumi. Eri and the others are very nosy about Kagome's personal life and are constantly worried about Kagome's health (which are really made up excuses while she is in the Feudal Era). Eri and the others often try to pair up Kagome with Hojo; a popular boy who admires her.
In the English dub version of the InuYasha anime series Eri was first voiced by Saffron Henderson. When Saffron Henderson left the Ocean Group for a brief amount of time, Eri was then voiced for the rest of the series and the third InuYasha movie by Rebecca Shoichet.
