>>1535206dam we got newfag in here. The YouTube scene in Japan used to have a trend where commentary videos especially about games always had the same Yukkuri-style format. I'm not gonna explain what the fuck Yukkuri is, that's your job as a newfag to lurk moar. But nowadays there's a bunch of different software people use like Zundamon (VoiceVox), and my favorite one Lilin-chan (Coeiroink).
