Yumemi is the main female character of the story, and the only person who can see the "floating islands in the sky". She is afraid of her ability because it makes her different from others, and has learned the hard way that most people don't believe what she sees. Because of this, she keeps her gift to herself, carrying a pink umbrella to block out the view of the sky. She is a dreamy, quiet, gentle person, with a caring and compassionate personality. Throughout the second OVA, she becomes more confident of who she is, but is still insecure about what she sees because of her special connection with Munto. Because of the connection, she is constantly haunted by images of Munto's past and is confused and distressed as to why she sees them. In the second OVA, Yumemi takes the initiative and becomes more accepting of her gift and role. She is the one to offer her help to Munto in the second OVA. As she grows in age she soon develops feelings for Munto as seen when she blushes and wears his red cape in the ending credits of the second OVA.
