Kirie Kanoe

In her first appearance, she warns Niiya about Yuuko.

Kirie is the only other character who can see Yuuko. She is a member of Yuuko’s family and looks exactly like Yuuko except for her short hair, ear piercings, and smaller breasts (much to her resentment). She later joins as one of the three members of the paranormal investigations club. The other members, Niiya and Momoe, seem to be her closest friends. Even after joining the club she remains apprehensive of Yuuko, but accepts Niiya's judgment.
