Kaina Tsutsumi (Lady Nagant)

However, Izuku Midoriya pointed out that she was not serious about killing Chisaki since the trajectory of the bullet he shot at her was wrong, and aside, he surmised that she is not that loyal to All For One as she appears to be, as she could have easily fulfilled her contract without having to engage in combat. It is later proven that despite her little faith and cynical view of society she still cares about doing what is really right in the end and that she became a heroine with the noble intention of helping others. After witnessing Izuku's skills in combat, as well as him managing to save her and Chisaki without hesitation, Lady Nagant considers Izuku a true hero.
