Couple of parts with weak or OK IB (though not what I'd call process) in a similar Manga called Dice.
Bunch of girls in the school become pretty when the Dice spread (Chapter 20) very weak imo, doesn't even show before forms:

One girl in particular who is featured heavily used the dice to become more beautiful / lose weight (Chapters 39 and 53 are good instances of IB before and after)

Not great but new-to-me content is rare these days so I figured I'd share.
EDIT: Another one also not great but, as above, content is rare, so here I share...

EDIT2: Another one that was new to me, short but solid, still not really any process though:
