I like original stuff more than fandoms and while I dislike Sword Art Online, apart from some really strong face->desk moments I actually liked the setting. Anyways these are the thing's I am interested in, in no particular order.

Sword Art Online 
Attack on Titan 
Mirai Nikki 

VampirexHuman 
Dragonxhuman
NekoxHuman
SisterxSister 

As far as idea's go I am sure we/you/I could come up with something, but as it stands for me right now I have like 6 different idea's for casual (and one advanced ._.) RP and I hafta sort that out first @-@
