>>93223268a lot of those early myth collabs were forced by management because myth was pulling insane numbers, stuff like myth vs nepolabo in amogus or gura and nachoneko playing mario kart and barely saying a word in an hour. for the most part it was awkward as fuck and no one really enjoyed them.
myth was also the only gen where 3/5 can speak enough JP that the collabs aren't totally awkward as fuck, whereas most of the other gens have 1 girl if even that. JPs don't really want to waste time doing awkward 1 on 1 collabs these days because it doesn't get numbers.
