This article, Day 1: Back to School, is the opening chapter of the Investigating Grat arc, which is part of Bleach: Cataclysm. It is a stand-alone segment set in the World of the Living instead of the Reikai, and focuses on Garrett Sheppard and his friends as the main characters. It begins at the end of summer vacation and picks up at the beginning of a new school term. "I trust your brains haven't gone to mush in the holidays?" "Oi, Garret!" "What?"
