Yachiru's stepsister. When Yachiru's parents divorced during the decade she went missing, her father remarried and Yachiru's new stepmother's daughter became part of the Nanami family. Slavishly devoted to Yachiru who is easily swayed by the constant and unending stream of flattery emanating from Himari's mouth. An actress employed by the Conglomerate to spy on Yachiru. She plays her part competently but secretly despises the shallow Yachiru. She eventually acquires Baroque powers after spending enough time gaining Yachiru's trust, these manifest themselves as exploding teddy bears (up to a maximum of six) which she can move at will to protect herself or to destroy her surrounding enemies. She uses the wheelchair as a means of getting around faster, her paralysis is just a charade. In routes where she manifests her powers, she eventually dies. Otherwise she is missing/presumed dead.
