She releases a Corona Chan cosplay in March/April 2020
LOTS of people call her out for it
Insensitive, racist, etc.
She is effectively canceled
Doubles down, wearing a black makeup mask for skincare with a caption that's like "I bet you butthurt SJWs will call me out on my blackface now"
Realizes doubling down does NOT work
Tries to make up a story about how she was groped in the subway
Nobody believes her, they keep calling her out on the Corona Chan thing
In the mean time, she's openly doxxing people who leak her shit on her discord (which is probably deleted now) and openly insulting other users. Remember that Youtuber, InvaderVie, who was like "I have all your personal info from your payments"? Mikomi did something similar, but she did reveal that personal info on her Discord.
Okay, she had cancer, but she also has a very problematic history as well that can't be denied. She used to actively astroturf her content on social media and 4chan-style imageboards, bringing herself up out of nowhere when people were discussing other girls. She also most likely bots her socials, with around 800 paid OF subs and 300 on patreon, she has like 2 mill followers on insta. Something doesn't add up.
And the you have her being sort of the spearhead or "leader" of the western european clique she always collabs with. She used to handle Pialoof's socials before becoming a cosplayer herself too, probably still does to some degree.
