Yori finds out that Yuki is a vampire after Aido protected her from a vampire who served Rido. Despite that fact, Yori still accepts Yuki and appeared to be more worried over the fact that she would lose her best friend. Yori parts company with Yuki when she is taken to a safe place by Aido on Kaname's orders. After the attack is over, she defends Aido when the other day class girls are afraid of him.
