The teacher from Dickson's School in Canada is the substitute teacher. She is here because of an accident that caused the math teacher to go to the hospital. (Some students didn't want to take a test, so they provoked an "accident.") Now, she is the new teacher until the other teacher comes back. After a few weeks, everybody notices that it is her first time doing this; she is super new to it and is a complete mess in the classroom after class ends.

Karugi: C-Come on, where is that task?! Eh, nani?! And th-this notes?
