Speaking of which, some animators and director I follow have tweeted they like Himaten, like Yuuji Tokuno in his private account (Director of upcoming anime Chitose-kun wa Ramune-bin no Naka, episode directors of Black Clover, Oshi no Ko, Fire Force, YAIBA), Tenohira, Miyaso, and Hinata Narumi, who even said she wants to join Himaten anime if it gets one.
Well, it's not really a confirmation or anything, but it's a good sign that some anime industry people are keeping their eyes on it.
