I've got a few
1 - In a small village, a young woman (Rina) runs away from home because she has the strange ability to transform into a wolf and can call upon the earth spirit to aid her when in trouble. What she doesn't know is that the humans she was living with found her as an infant and kept her away from the forest in order to try and keep the fact she is the daughter of a fierce pack/tribe leader. But when she finds her way into the forest, away from humans, she accidentally stumbles upon a tribe of demons (wolves, neko, ect... whatever is a preference). Instead of being welcomed, one of the tribe members sees her as an intruder...and as leverage as they realize she is the daughter of their enemy tribe/pack.
2 - (mixture of FF7) An old legend becomes real when Sephiroth, the one winged dark angel, rises up for an unknown reason (I'd require you to play Sephiroth and decide what he wants to do lol) But, when Sephiroth rises, a young woman experiences a strange reaction, learning very quickly that she has an odd connection to the one winged angel, but its a connection that could very well be used to destroy all humans should Sephiroth learn to control her as he wants (the details are a bit foggy... I guess we'd come up with a basic plot, like what kind of connection she has with him, ect...then let things play out if you like this idea)
