Sup! The body mainly goes by Ethan or Aarran, the body is mixed race (asian and white) and transmasc. Please use He/Him if you don't know who's fronting U_U
I'm not the most open about being a system but if I link you here it means I trust you LoL.
Most roles are unknown because alters front so rarely and when they do I am rarely cognizant of them fronting so...ewps...these are just the guys that were prominent at one point or another
