Sorry it's a little late.

Circle 3 is just the execution of X's plan.

This, however, is a filler chibi that I used to organize my notebook. Basically I'd have the notes on the left and the homework on the right. Made it real easy. Problem was that we didn't always have work from the book, but instead get worksheets. That's when I would do 'Fillers' to take up the space. I tried to use characters not in that days comic, so that's why I'm doing it instead.
