Right, let's see if I can address everything that's been discussed (feel free to poke me if I don't).
Leo, you said your character has limited shapeshifting abilities. I believe that to shape-shift into other yokai, it would take considerable practice and would sap most of his energy, so I don't think he should be able to turn himself into gargoyles/golems or any other stone creatures. He is after all, half-blooded, and this makes him considerably weaker than a full-blooded Leshy. I think that his abilities should be limited to small to medium-sized animals for now, and as the RP progresses and he interacts with everyone else, he could try imitating them, but still not completely perfect their appearance (perhaps just a part of their body at the beginning). Maybe after you form a partnership with someone, you'd be able to imitate them perfectly, as you'd be spending more time with them than everyone else and have lots of time to observe their movements. Also, I hope he doesn't shape-shift too often during combat as it would make things a tad annoying. xD
The point of the partnership is to work together. I won't put you all in combat situations too often, but in cases that you do face enemies, you will not be able to face high-level demons on your own. Even low-level demons in large numbers are supposed to tire out a duo. Humans are no match for you, but pure-blood yokais are to be treated with caution, no matter how powerful your character is. Speaking of which, Len's CS is accepted. :)

EDIT: I'd like to know how many of your characters are new residents or how long has your character been at the building. My character has been a resident for 3 years, so she'd know some of you if you choose to be an old resident.
