He sees a smaller group of villains in the safes gathering up money. It seems pretty well thought out-they have a villain with superstrength busting down the safe doors, and a villain with a warp quirk, using his portal to transport the money quickly. Akui is among these villains
He realizes that Akui was standing behind ALL of them, using them as a shield. He smirks
"Oh really? Then perhaps I can make it more interesting."
He lifts up his eye patch, revealing a cold, dead eye underneath, just absolutely terrifying. He looks Bakugou dead in the eye-and he suddenly finds himself frozen in place
He covers his eye back up with the eyepatch
"There...now I wouldn't try to move too much, my love. Otherwise you may just crumble into dust. I've left that pretty face of yours untouched though...I do so enjoy listening to my enemies posture..."
Bakugou is stone from the neck down. Akui looks over at his stunned team
"Now then, anyone injured?"
