I hang out in Hokkaido most of the time on [GC]-Ai.Takeda, although I can occasionally be seen on the other characters in my signature. My timezone is GMT +0 (England), so i'm normally around after about 4pm GMT until about 10-11pm GMT.
I try and get all GC players roleplaying as best I can, and hopefully I've achieved a decent enough RP within the faction. Either way, Kusari is where I normally hang out.
