Is she firing her gun while doing a princness carry? Looks like holes are appearing in Charlotte.
She probably froze time, placed bombs around Charlotte, then went back. The only problem is how could Mami be frozen at the same time unless Homura dropped her first, which apparently didn't happen.
You're heavy!!PugyuThis is the first time I've had such a tiring fight!Just how long do you expect to be carried!?You really are useless after all......You'll really fight alongside me from now on?... You'll stay by my side?... That's the plan.... Well then, after we defeat this Witch, let's have a party!To celebrate me and Homura becoming the formerly-bullied child duo!That's fine, but...... I'm so scared my legs just gave out...
