Intro
Morning at Satsuki High School was as noisy as ever. A wave of students overflowed at the entrance, and laughter echoed through the hallways. Some time had passed since the entrance ceremony, and the cherry blossoms had fallen, replaced by fresh green leaves.
Tsukito, the homeroom teacher for Class 1-5, stood at the podium today as well, reading off names matter-of-factly with an attendance book in hand. During morning homeroom, most students still looked sleepy. Some could be seen sneakily fiddling with their smartphones.
There was one empty seat next to Yasuchika. A gaping hole in the space for one person. Tsukito's gaze flickered toward that seat.
