Moondom isn't intended to be a broadcast/streamed show so this is really the only (small) clip from the show along with some small BTS shots. Waka also has a small speech in the ring (and I forget who it was here who had been inquiring about the possible English proficiency of some of the wrestlers, so you can get a good sense of Waka's English skills here).
Waka made a few ChocoPro appearances prior to signing with Stardom. She introduced herself to the viewers in English and blew us all away. She was liked immediately and some of us (myself included) were disappointed that she signed with Stardom, because it means we'll probably never see her in Ichigaya Chocolate Square again.
Wouldn't surprise me if it happened eventually. With how the wrestling scene has been going in a post-AEW/post-COVID world, more and more companies have been working together, using each others talent, etc etc. I know Stardom's always been a bit more closed off, but more and more of their talent have also been branching out lately, going on other promotions shows, going overseas, etc. With the recent NJPW announcement of the \ a day or three ago, it won't surprise me if things keep going further and further in that direction and Stardom ends up working with even more groups.
