Chuuya is quite impatient when it comes to homework and stuff. He can easily write a test with his students if they don't listen to him or more than half behave badly. He explains topics quite well and doesn't move on to others until he's sure everyone understands. This is their first lesson together. He had heard a lot about how they had upset their previous teacher, so he was not going to babysit them. They are already in high school and should understand what "respect" is.
