Mima (EntityTopic, 7)
From Compile Worlds
Mima is an awesome but somewhat crazy "fake ghost" youkai from the PC-98 Touhou games. She seems to have a recent liking with Ms. Donotwant after her plans of revenge were foiled. But wait... did she just insult the Hakurei Shrine? D:
She's Marisa's teacher, and seems to act as a mother to her. Well, a mother crazy enough to spur on Marisa's relationships with various other girls, that is; ironically, Rinnosuke's take on this is that the real pairing is between Marisa and Mima herself! Does this count as incest?
She appears most awesomely in Touhou Mother (no pun intended), where she is apparently sleeping until Marisa is kind enough to attempt to wake her up, fail, and almost go out of character and cry about it... which in the end succeeds in waking her up anyway.
Despite being awesome and spammed just as much as Marisa was in the PC-98 days, we see next to no sign of her existence in the recent days, other than that little loli's record of the days of old. Dammit, ZUN! Well, she'll always appear in the next game... even if she doesn't.
