This is actually interesting at some extent because i think it have clues about ciconia, especially these 2 parts:

"(...) which meant that at present, neither Une nor Takano had spread anything at all. The world had yet to reach the point of no return. In other words, if Une's ambition could be halted on this day, then it would <<<<< all end before it started>>>>> but that was impossible. <<<<Without a time machine !>>>>"

and: ""Oh-ho? So you humans are challenging the gods? Then we won't hold back either!"
Tamurahime-no-Mikoto was a steady player. Her style focused on defense more than offense, so she should've been a tough opponent ( Vier side?)

Une was likely to toy with us magnificently using her sly tricks and fluid adaptability ( definitly Toujirou Mitake's side)

Then Hanyuu had her indecipherable dumb luck. She was the greatest opponent in a game involving chance" (three kings maybe? but idk) (and miyao's side would be mion's group obviously)
They were still gods. There was no reason for then to lose a game to humans"

I may be overthinking to be honest but i just thought it was interesting.
