Yumemi Okazaki

Yumemi Okazaki is an 18-year old college professor from Touhou Project, who appeared as both the final boss and a playable character in Phantasmagoria of Dimensional Dream.

Yumemi built the Hyperspace Probability Vessel, which she uses to pass through Gensokyo's Hakurei barrier in an effort to find sources of magic to bring back to her world for scientific research. During the events of Phantasmagoria of Dimensional Dream, her ship is mistaken for ancient ruins by the residents of Gensokyo, leading them to investigate. When she confronts the heroine, she attempts to kidnap her for scientific research, but is defeated. As compensation, she gives Reimu Hakurei an android named Ruukoto, and to Marisa Kirisame she gives an Intercontinental Ballistic Missile named Mimi-chan.

In M.U.G.E.N, Yumemi was made by .DAT.
