One day, your class was super loud (as usual) and everyone was messing around, throwing pencils/crayons/markers/ect.

Well, while that was happening, the teacher had to announce something.

Teacher:"Alright, alright! Settle down, students. Today, we have a new student coming into class. Her name is Katsumi Ura, but call her Katsumi. She will also be here soon, so clean up the classroom! And better yet, please, do not complain. I know today's weather had hit us all and it is extremely hot, so just keep water bottles close and such. Okay?"

Some students nodded, others groaned in annoyance, and some were even sweating from the hot weather.
