This is an appreciation fic, where I thank Yusei Matsui for giving us the wonderful time of reading Ansatsu Kyoushitsu. We are the 29th students of the End class, we learn with them in the weekly manga updates, and we graduated together. So I guess... On behalf of the Ansatsu Kyoushitsu fans, I would really like to thank Yusei Matsui for introducing us Koro-sensei, and the E class.
