>>2967764i'm only a shuujin so i can only give you info about mito. she's pretty much a free spirit that does whatever she likes at her own pace, so she doesn't stream way too often compared to other girls because she either spends her day reading manga or watching backlog or actually goes out of her house to have fun/gather materials for her experience report streams. her personality can be easily surmised as eccentric and probably deranged, but she's actually pretty resolute and can be serious at times. one of mito's appeal is being verbose and explaining things in a well put manner that can make watching crap games actually enjoyable. as for mito's manager, she has cycled through many internal changes already, but they don't regulate her way too hard as far as i know. sometimes her even manager accompanies her to her trips for zatsudan material gathering, but she doesn't stop mito from going to vore cafe and other weird shit anyway, or from disappearing for about 2 weeks without telling the public. mito mostly regulates her own content when she thinks its going way out of the line. most regulation that she gets is staff taking forever to get permissions for game she likes and getting some of them shot down for reasons, i guess.
that's all i have to say, pretty sure other people can tell you better about other niji girls.
