>>89372810Zen is an embarrassing remnant of the fact that the pre-holoEN boom twitch vtuber scene had so few options, that they unironically considered AND went with a TTS tuber who would today would be either done only as a joke or would otherwise be unlikely to hold more than like 10 non-raided ccv.
As to why it somehow got a big fanbase, literally it's just because it streams a lot and is dragged upward in visibility with vshojo. Basically if you are the vshojo equivalent to genmates with Ironmouse, that has its perks. Otherwise it's like 999 out of 1000 odds zen would have gotten left behind as the scene developed and there were so many actual-girls streaming that he'd look like a joke in comparison. Also, boobs. When all else fails lean more and more into sex appeal, as much as twitch allows.
