Fujiwara no Mokou

Fujiwara no Mokou (literally 'Mokou of the Fujiwara Clan') was formerly an ordinary human, but she became an immortal being after drinking the Hourai Elixir about 1300 years ago. Now she is never able to die, though she still feels the pain of injuries as normal. She's considered to be very powerful, given her long life, the power she earned through her life, and her immortal status since she can keep fighting until she can no longer stand the pain. One of her main jobs is youkai extermination, though she seems to be settling on guiding visitors to Eientei in and out of the Bamboo Forest of the Lost. Around 1300 years ago, Kaguya Houraisan embarrassed Mokou's father, and her entire family, by presenting him with impossible requests when he asked for her hand in marriage. Mokou grew to resent the moon princess, and searched for a long time for a way to spite her.

In M.U.G.E.N, Mokou has been made by various authors, including HM, Minoo, Kohaku, RicePigeon, and Isu.
