my fave is chara. i don't usually like answering this question cause everything i want to say would be too much for a single post, and it's also hard for me to explain "why they're my fave" partly because it kind of just happened. like, you get to know them and then you just start feeling for them a lot and then you end up completely obsessed with them. something like that.
but i guess one thing i can say is that the more i started thinking about them the more i wanted to be their friend, and to be there for them when no one else is/was, and to listen to them and try to understand them and love them no matter what. i just feel this weird connection or kinship with them that i don't always know exactly how to explain, at least not without going on and on. i'm not sure if that makes sense. but that's essentially the way i feel.
