|This article is about a/an ally in Juken Sentai Gekiranger.|
She is an assistant to Master Sha-Fu and also a student of Fierce Beast-Fist Beast Arts, mastering the Fierce Beast Leopard-Fist (激獣レオパード拳 Gekijū Reopādoken) style. She was originally part of a previous triangle under Sha-Fu and Dan but became the only member to stay loyal to Sha-Fu and the teachings of Geki Juken, with her partners being Rio (who would abandon the path to follow the teachings of Rinjuken) and Gou Fukami (who would instead develop his own Shigeki style and become lost trying to bring Rio back).
She dislikes Elehung, even though he is attracted to her. Before training in Fierce Beast-Fist, Miki was an infamous sukeban in her youth and the former leader of the Kanto Sukeban Alliance. She also knows the SGS's Morio Makino from the Dino Curry she usually eats at. Her daughter, Natsume occasionally drops by to see her at SCRTC.
