S1·E2 Are We Becoming One?

On his way home from school, Kouta runs into girl his age that he intuitively senses is a spirit like Chizuru. The following day, the same girl appears in Kouta's class and is all over him, much to the annoyance of Chizuru. She is introduced as a transfer student named Nozomu Ezomori from Hokkaido, though it is soon revealed to Chizuru and Kouta that she is from a powerful wolf clan. Nozomu continues to get in the way of Chizuru's plans to get close to Kouta due to her own such desires for Kouta.
