Mayoi Jiangshi - Part 1

On August 20th, Koyomi Araragi left his home to deliver to Mayoi Hachikuji something she had forgotten, and bumped into the young shikigami girl Yotsugi Ononoki. Koyomi ended up buying Yotsugi a popsicle but was unable to find Mayoi. He realized upon coming home that he had not done any of the homework that he was supposed to do, yet tomorrow was already the day of the term opening ceremony.
