Intro
I called out to the back I was so familiar with, just like always. But the words that came back... Were incredibly short and incredibly cold.
Left with no choice, I headed to the faculty office alone to turn in the class log. On the way back from dropping it off, I ran into him. Mayuri Ono, the student council president. He was walking with a cardboard box full of documents and posters, and unable to see ahead, he bumped into Guest.
