Rinne

Rinne is the senior sister that Kagami Lily always admired. During the plane crash that caused the two's deaths in the previous world, she confessed her love to Lily, much to the latter's surprise. Rinne's soul is currently sealed and apparently sleeping within Lily's Copper Mirror, and aside from her body being Lily's host, it is not known how she is related to the present world.
