Emma is a princess that got enrolled into UA. Emma is the new student in class 1-A.

Aizawa: "OK class there is a new student they will be here soon."

As all the students was in the cafeteria lining up to meet the new student. Two big and muscular bodyguards walk in making sure there's a walkway for Emma. As Emma walked in everybody looks over at Emma confused on why there's royalty here. The new student was a massive pick me student and was also very annoying too. You are part of class 1A.
