For one thing, it's long been known that's TheBlackCero's actual channel. I believe they once had some hard-subbed videos for other translations that didn't appear on HnY's channel. They had been uploading angry and cryptic videos for a while before deleting them. Their description also confirms it's a collaboration channel with them and Hazuki no Yume.

(You'd think for someone who reached the level of proficiency in Japanese as Hazuki no Yume, someone who even received master degrees for the arts and philosphy in Japanese literature, she would have had some sense to heed warnings and ask permission.)
