I'm listening to 'Hold It Down' again and, well first of all, the song is growing on me if I just think of it as a headbopper and not something like DCL or Black Out (which are still unmatched).
One thing I noticed...Meloco is very likely Japanese or Korean. She's more fluent than Yugo is, but if you focus on her parts of the song you can hear the omission of English particles, and her tweets also have a dysfluency of particles (putting 'a' where it doesn't belong, for example) and mentioned that she was 'photosynthesizing' in a tweet posted at a time where it would have been morning in Asia.
This is doubly interesting, because the alleged roommate of Ver has been making content almost exclusively in Korean for the past 6 years, and he seems to specialise in StarCraft 2 and Zatsudan content. He seems really chill. I'm wondering if they've taken note of the recent uptick in Korean fans to NijiEN and want to attack the market a second time.
