This is a story about Class 5 of 6 years becoming Class 5 of 9 years after many "tests"~
What is class five? We dare to do what other classes dare not do.
We dare to scold what other classes dare not
So what if I'm not good at math? Let's physicalize it~~
Our life is comfortable
What is our recess entertainment?
Everyone said: "Aruba!~"
This! It's Class Five
