Unhand me, you villain!

Actually I think that's part of Botan on the right edge of the cel, and the two girls are fleeing the zombified Tokyo residents that are chasing them around the school grounds. I just couldn't resist quoting the famous silent melodrama title card, which seems to go really well with Keiko's expression.
