so i saw this channel that is getting 3k on Vstats and got curious.
Turns out it's a corporate channel for Heiwa Corp an old-time Pachinko and Pachislop producer. The YT account was created and started uploading 8 years ago, but their vtubers were only debuted last year.
They are a pair, HaruLuna, consisting of Haru and Luna. They do pachinko streams regularly, but also have personal vtubing content on the channel. Picrel was their 3D live 3 days ago, genuinely Edo idols, very japanese and NND feeling.
Obviously my limited research might not uncover everything, but this looks like one of the few corporate mascots that do get treated well and enabled as vtubers. Having 3D after 1 year is good, and they seem to be enjoying their job.
Numbers are pretty good too, 2,4k so far for this stream:
