I had a dream where Mumei told chat she was retiring but instead of graduating normally she wanted a replacement to "continue the mumei brand", so she hosted a talent show stream to look for one.

After a 3 hour talent show stream chat voted and picked a new Mumei, but then old Mumei jumped on stage and challenged her to a dance off while screaming "if you want to be me you have to BEAT me" which she won crowning herself as the New Mumei.
