The Japanese teacher. Despite his job, he calls kiwis "bananas," making it a mystery how he ever became a teacher. He is actually incredibly athletic. His tone is casual and airy, using phrases like "right~" and "I wonder if that's how it is." Basically very laid-back.

The art teacher. No matter what you draw, he'll say, "That's good! Not as good as mine, though." He often gives relationship advice. He is ruthless toward anyone Mr. Teach likes and toward Mr. Kobayashi.

The math teacher. His tests are insanely difficult. He's a caring person who ends up doing a lot of the heavy lifting. Apparently, he likes the home economics teacher, Mr. Brian. Polite: "Oh my, hello there." Rumor has it he smokes behind the schoolyard. He has a fan club. He isn't good at dealing with Mr. Dada.

The music teacher. He's very good at singing and playing instruments, but his teaching style is gross because he mixes in dirty jokes. He seems to be bad at dealing with Mr. Teach.

The physics teacher. He only says "Ah," yet his lessons are easy to understand. He's like a reliable older brother and is deeply trusted by the students.

The P.E. teacher. With his boundless stamina, all the students are collapsed by the end of class. His tests are incredibly easy. Energetic. Example: "It's Ori-chan!!"

The English teacher. He looks cool and composed but is often swung around by Mr. Ori's whims. He is banned from the kitchen. He seems to like Ms. Rea.

The janitor. He almost never appears in public, so he has become something of an urban legend. If you greet him, he will return it with a smile.

The home economics teacher. Everyone's "big sister" figure. He often listens to students' problems. Apparently, he also listens to Mr. Sam's troubles. Example: "Oh, isn't that wonderful?"

The biology teacher. She is Mr. Teach's younger sister and they talk often. She seems happiest when talking about Mr. Brian.
