Ichiko Ono (Ono Ichiko) is Yumemi Hidaka's childhood friend and classmate. She always encourages Yumemi and protects her. But Ichiko is co-dependent and controlling. She always wanted to see the island Yumemi spoke of and wished for the day she can see them. It is revealed that she is the reason Yumemi carries an umbrella in the first OVA and is afraid that the "red man" would take Yumemi away. Ichiko often tries to convince Yumemi that Munto and the islands are from a different world and they do not belong there. Ichiko's character is described as athletic and popular at school, but Yumemi is called "space-cadet" and Suzume as "childish".
