Huh? So they're not replacing Sumino with her sister, they're recasting her? Maybe it'll be some weird side effect of Sumino using the Donbrothers Sentai Ring.
Also, just to clarify, the tweet says (according to X's autotranslation) that "She will appear starting from episode 40," so it's not just for the one episode.
I'll be glad to see the lovely Kohaku Shida again, and she should be a reasonably good fit for the character, but the circumstances are weird and unfortunate.
According to RangerWiki, GozyuUnicorn is voiced in episodes 37-39 by Ayaka Maekawa, who's voiced various returning "Female Sentai Warriors" in several crossover movies as well as the mecha Mashin Carry in Kiramager. This is the second time Maekawa has understudied a Gozyuger cast member; in Kamen Rider Heisei Generations Final, she took over the role of Mezool, who was voiced in Kamen Rider OOO by Yukana Nogami, the voice of Gozyuger's Queen TegaJune (and of Honoka/Cure White in the first two seasons of Pretty Cure).
