Itsuka is a very high-spirited, thoughtful, and well-matured girl that knows what's best for others, including with her discipline towards her classmates (Mostly towards Monoma) in making sure she leads them well and have a more friendly relationship with the students in Class 1-A. She's not one to hesitate and criticize of what others were doing is not right and sometimes she needs to make sure it doesn't happen, like when she karate chops Monoma on his neck whenever he senselessly antagonizes or threatens the Students of Class 1-A (as well as when Monoma gets carried away with it).
