The majority of Class 1-B's students share a rivalry with Class 1-A. However, certain students such as Neito Monoma take their rivalry to extremes out of jealously of Class 1-A's popularity and strength and thus 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 Shoto and Katsuki 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), the two hero classes are on neutral terms with one another. There are a few in the class who do not outwardly bare ill-will towards Class 1-A and behave friendly towards them, such as Itsuka Kendo, Tetsutetsu Tetsutetsu, Ibara Shiozaki, and Setsuna Tokage.
Ultimately, the two classes are able to put their differences aside when necessary, (which the exception of Neito Monoma, who seems obsessed with the rivalry beyond reason) as shown during the attack by the League of Villains on the mountain training camp when the members of class B readily accepted help from class A’s Momo Yaoyorozu, with Yosetsu Awase risking his life to protect Momo from Nomu.
- Class 1-B is the only first-year class of U.A. High School to have all of their peers pass the Provisional Hero License Exam in comparison to Class 1-A.
- According to Neito Monoma's survey of the U.A. Cultural Festival, Class 1-B beat Class 1-A by two ballots
- However, his results may be doctored since Neito's survey was "self-researched."
- Class 1-B"s play "Romeo, Juliet, & the Prisoner of Azkaban: The Return of the Kings" is based off Romeo and Juliet by William Shakespeare, Harry Potter and the Prisoner of Azkaban by J.K. Rowling, and The Lord of the Rings: The Return of the King by J.R.R. Tolkien, respectively. In the play there is a scene where Romeo, played by Neito Monoma, confronts an antagonist, played by Tetsutetsu Tetsutetsu, who confesses to him that he is Romeo's father. That scene is a clear reference to the Star Wars franchise. A character called Obi-Wan is also referenced.
- Class 1-B is also the only class with confirmed foreign-exchange students.
