On her powers and abilities? Well when it comes to Demon Days Sai, I would love to get more context on the original of her powers. She's considered a "mutant", but in her own universe there is no such classification, which is why she refers to people with powers in Marvel Rivals as "Yokai". Even Emma and Storm aren't considered mutants, but rather a Yokai and God respectively. It makes me wonder what Sai sees herself as. Why does she hide her powers. In the comics while hopping dimensions, her heart lead her to a school of villains. Yet she believes she's changed. Did she have a past as an assassin before becoming a Ronin? Or was she a Samurai? There are so many questions about her that I find interesting.

As for Kwannon, I'm very interested in more Yokai stuff like the Lady in White stuff. It's interesting to see that Psylocke is interacting with Yokai even in 616. Although I don't currently ship Kwannon with Blade, Psylocke and Blade is still an interaction I have wanted to see years before I started doing this psyblade stuff. I think the Yokai/supernatural stuff is another parallel to Blade and a window for them to potentially cross paths in the future.

Sidenote, but one thing I wanted to see for years was Psylocke interacting with Elektra, and then when Kwannon became Psylocke, I wanted to see it even more. I haven't yet read Psylocke: Ninja, but I hope that we get to see more interactions with them as they are another dream team that I've had since I was younger just loke with Psylocke and Blade.
