mimiirose were launched by an agency that was at the other end of the scale from the Big Four, as can be seen from this Reddit post:

The debut took place with a "half video"; the original MV came to a halt after the first chorus, presumably because not enough money was available. Only later was a full MV released.
Nevertheless, the debut wasn't one of those nugu releases that looks and sounds as if it had been recorded on a flip phone. The song is actually rather good, although I don't know how well it did in terms of sales.
I haven't really followed mimiirose since then, although I know they have changed agency and had a recent comeback.
