Thankfully for Rika, Vivian followed after the older girl without a word, her floating bunny plushy not making any move to leave Vivian just yet as they, well, pushed themselves through the crowd. Maybe they'd get lucky and the hydrant destruction wouldn't get all over the news.

Maybe. Hopefully.

... Yeah. No. Vivian was probably completely, and totally in trouble.
