An enigmatic maid sent by Ayumi's father into the service of the Yoshikawa household, apparently to collect data. An effective maid, she is taciturn and quite able to cause trouble and thwart Ayumi's attempts to seduce Haruo. Her seeming obliviousness to the present conceals a calculating cunning that rivals even Fuyuno's. It is later revealed that she is an artificially-created human. The sound of a cymbal solo - A short musical quotation from The Terminator - follows her as she goes into action.
