>>108130500Lumi does it becuase the content she tends to do on YT are skits or chat RP's, and games on Twitch.
Tenma does that too but when it comes to games she just has a preference of what type is played where, and keeps that series to that channel specifically.
Runie does the same thing as Lumi except simulcasts when playing games.
I imagine it overall its easier to tardwrangle when you're only broadcasting on one channel
