Niina's:
NiinAsami! This was an entire episode dedicated to NiinAsami!! It was really cute too. Niina waiting for Asami to return from a business trip like an anxious housewife. Going on a date with her to refresh her body and mind in different ways. And of course Isuzu's massage service which is somehow really popping up everywhere now.
I think what I liked is that even when their hearts were unlocked by Isuzu it just kinda helped them establish their dynamic more and showed how much they really think about each other.
And Isuzu's final comment is so good.
Love it.

Muua's:
Ghost Hunters! Muua is scared of ghost rumors, because she can befriend any human apparently, but ghosts cant be friends... Honestly this clearly subtly plays into her trauma and fear of dark places. You can literally hear her revert to her childhood self when she remembers watching a horror movie with her sisters.
Koju is becoming the most reliable person around the base. She is just always up to support people and throw hands with evil apparations.
The twist was funny as usual, but for some reaosn Muua episodes always turn out to be wholesome in their own way. I really love this dork.
