Hmm... Yuri could go back to her house and fetch that book of seals and exorcism rituals, and then have Selina...
Oh, right. Shit.
Well, we do have access to holy magic, so we migbt be able to use a non_empowered circle.
Or hell, ask fucking Anima. You know, the person who performed a soul transfer between bodies, literally about less than a day ago. Without a hitch.
Also, you happen to have Alexander, who's made constructs already, constructs, I might add, were fleshy and squishy. Nobody bothered asking the great teacher Chiron about things either.
Really, the robot thing is pretty unecessary when we've got about two or so contacts capable of making fleshy bodies perfect for Luna to hurt as much as she likes.
