Yumemi Okazaki (EntityTopic, 11)

From Compile Worlds

Yumemi Okazaki is some kickass dude dudette university professor from another dimension that has children that graduate college at 11 and leave graduate school at 13. She's constantly inventing, travelling around in, and crashing space-travelling spaceships, looking for magic ever since that incident that caused her to be a laughing stock in her world. Pretty much the only one to believe her and her silly little theory is her subordinate, Chiyuri Kitashirakawa, who, herself, is kind of a weirdo. In the end, she fails miserably and has to keep her promise of fulfilling the wishes 2/2RuukotoMimi-chan of the ExPar: unexpected pipe of the contest she just made for the sake of finding a winner and taking her home for science.

She then appears in Touhou Mother, but not in her search of magic. Who the hell knows why she went back to Gensokyo, anyway? Well, she and the Mr. Saturns were a lot of help, anyway... when she's not spying on girls dancing in the moonlight inside a humongous robo.
