Ying Ruqiu is a sixth grade student
In some places, they are called primary school students
And some places call her a junior high school student
Actually it doesn't matter
She is so smart that she can even understand the classes in the third grade of junior high school.
The school also has a primary school and a junior high school
She is a genius girl
Is it really suitable for this world that seems innocent and ignorant to her?
Maybe it's really not suitable...
