Reimu is the connection point between the "children of the night eye's" She's a ghostly spirit who helps the organization get to destinations quickly with her power. She has brother and sister spirits that help coordinate locations.

Her brother spirit Ryou and her sister's spirit Reiko are the second and third oldest beside her. Her and her siblings are based off the folklore "Black eye children" Dimension Main

She speaks softly, and gently, almost like a loving mother.
