Class!(open)

Umirin cautiously entered his designated home room and saw his teacher, "Hello."

The teacher looked up from his book and pointed towards the desks, indicating for him to take a seat. There were a few students already there, but it was mostly empty. Umirin took a seat in the front, on the opposite side from the other students. CHAKRA was written on the board.

Sitting at his desk, Umirin rubbed his legs. His whole body was sore from training this morning, but his legs had it the worst. It oddly felt good. What did dad call this muscle? The quads? Umirin smiled and sat back. His body felt great. He could sit here all day, waiting for class to start...

Umirin opened his eyes, realizing he fell asleep, "PRESENT!" he yelled out, figuring the teacher had just woken him up... the classroom was empty.
Umirin looked around. The desks were empty, the teacher was gone and it was night outside.
He stood up and slid open the classroom door: the hallways were empty and dark. "This is not happening... Did I just fall asleep before class, nobody woke me up during class, and on top of all that, left me here when class was over?"
Confused and a little afraid, he grabbed his bag and made for the exit.
