Due to Shizuka's untimely death, this promise is never fulfilled. She seems to be fond of Ichiru, hugging Zero when she mistakes him for Ichiru, and asks Yuki to tell Zero that if he sees Ichiru, to tell him Maria wants to see him again. She returns to her family after Shizuka's death.When she sends an owl out to search for Ichiru, she witnesses Kaname's destruction of the Vampire Council and proceeds to spread the news.
