Today, 31th march, 2020 Kochou Momiji will end her work as Virtual personality. Currently she's having 24h stream on Twitch that will end at 21:00 JST. After that (or even before) her Twitter, Youtube channel and other social media will be closed by company. The official reason that she gave is her graduation, but there are also gossips about company she's working for having problems.
It... kinda sucks, especialy that she's one of the few Japanese streamers that is fluent in english and more often is interacting with her western fanbase than japanese and was overall working more with western streamers, too. But oh well, ultimately everything ends...
