Think about it. When was the last time you ACTUALLY saw Millie's Hat? We've all known it wasn't getting the support and promotion from Niji and Millie it deserved. Nijisanji keeps screwing over even its inanimate objects for far less talented livers like MH's crownwarmer.

People have been speculating on why Kiara was fraternising with Ethyria. I think the answer is now obvious. JCorpo autism makes it very difficult for Hololive to rescue a Liver, but that doesn't apply to rescuing a Liver's accessories. Millie's Hat is finally in a better place where it can form a warm a head more deserving and appreciative.
