Notes:

(NSFW just in case)

Title of the card is: "Kaguya wanting to undress him"
She seems to be saying: "Yay I saw his underpants!"
Her apprent tittles or type being "Shuchiin" and "Vice President".

What seems to be her effect is: "[AUTO] When your climax is placed on your climax area, this card gets +1500 power until end of turn"
And
"[AUTO] When this card's battle opponent become [⌄], if there is a climax in your climax area, you may pull the top card of your deck into your stock."

Oh and her CH is 4500…

I have no idea what game is being played, but all I can say is this makes me want to check this anime out soon!
