It's me I'm the friend :D :D XD I was coming back with no other answers and was gonna give a way less detailed reply, glad you got here first with all the Himiko/Ochako love <3

I just can't figure out what it is with Kyouka/Momo, haha... We haven't seen much of them recently, and I can't remember the last time they actually shared a scene! Maybe it's the background ship aspect, or maybe there's a super cool event happening somewhere we can't see :D

I might try to ask on bnha_fans and see if someone has a theory or hint!
