Class 1-B is another class in U.A.'s Hero Department next to Class 1-A.
The majority of Class 1-B's students bear ill-will towards Class 1-A. Students such as Neito Monoma are jealous of Class 1-A's popularity and strength and desire to topple them. So far, Class 1-B appears to be making accomplishments of going beyond Class 1-A's performance. This is evident when only one of the Class 1-B students (Neito Monoma) failed the End of Term Test while five students of Class 1-A failed. Further, all of Class 1-B passed the Hero License Exam while Todoroki and Bakugo of Class 1-A didn't.
The interactions between the students of Class 1-A and Class 1-B have been few due to the rivalry between the two classes. While Class 1-B treats Class 1-A as rivals (Class 1-A appears to not return the rivalry), ultimately, the two hero classes are on neutral terms with one another. There are a few in the minority who do not bare ill-will towards Class 1-A and behaved friendly towards them, such as Itsuka Kendou.
