To be honest? I think HoloEN is extremely bland and boring. They're nice people (I guess) but the content is too stale and sterile. I'm grateful for them being the gateway for newfaggots getting into the "genre" of vtubers but I implore you watch other talents outside of them. You'll quickly find that HoloEN is relatively mediocre after watching other vtubers, including HoloJP. Some of them may be talented but that talent doesn't make them an entertaining streamer and unfortunately streams account for 95% percent of their content.
