Okay, I'm not going to judge any bios until I talk to Tachi, but "neko" is just the Japanese word for cat. ^^; She'd have to be a nekomata, or a bakeneko, or a beastkin or something like that.

Name: Fubuki Eiki
Race: Oni
Age: 59
Appearance: [url=http://vitavitaar.deviantart.com/art/Oni-494957721]"HAI!"[/url] She has very lightly tanned skin, dirty blond hair, and green eyes, tending to wear red kimono. The bow on her tan horn(both are tan) is darker red.
Personality: Lacking any sense of shame and seemingly lazy, Eiki can often be seen lounging around, especially in hotsprings. She really likes hotsprings. However, this is quite deceptive, as Eiki actually has a high amount of energy when she's excited and moving. The oni girl has a fairly happy and friendly disposition, as well as being extremely confident with herself and really quite full of herself. She also possesses a very strong sense of honor against non-monster foes. To the embarrassment of all around her, Eiki has a total lack of any sense of shame and is incredibly difficult to embarrass. She takes a great deal of pride in her body, in fact. She has a whole lot of pride in general, really. Eiki will fight monsters, but she's not to thrilled by them unless they're smart enough to have some kind of planning, and would much rather fight people. She treats fighting in general like a fun game, really. She refuses to use weapons, fighting only with her hands and feet. And elbows. And knees. And anything other part of her body that she can hit someone with. Eiki is also deeply fond of sake.
Skills/Abilities: Eiki is an oni, possessing massive amounts of strength and physical durability, as well as an inhuman ability to heal her injuries. She far outclasses humans in terms of raw physical might, but a good fighter can close that gap and she's liable to hold back to make things more interesting if they can't. She is skilled in hand-to-hand combat but has no training in using any sort of weaponry.
Equipment: Lots of kimono. Nothing else. The only clothing Eiki ever wears is kimono.
Brief Backstory: Eiki's fifty-nine years have been spent on lounging about, fighting, and drinking. She's pretty much spent her whole life on doing such things, and also finding fun people to team up with. Or fight. Or both.
