>>71918972The oshi part is a joke, but it stems from all the recent examples of Mori talking about Fauna as often as Fauna talks about Mumei. After DOTA collab she admitted in her next stream (zatsu/drawing I believe) that she joined solely because she wanted to play with Fauna. When they played Palworld many people noticed that "WTF why does Mori sound nervous when talking to Fauna?", and so on. Even during her climbing game she ended up watching Fauna's stream for reference.
It's fascinating to follow her doing all that, really.
