Miraculous LadyBug: Season 2, Episode 5

2 - 5: Riposte

On the fencing court, Marinette has hopes of joining to impress Adrien. Armand assigns the new recruits to pair with the experienced ones. A new student, Kagami Tsurugi, the daughter of a famous fencer, moved in Paris and challenges Adrien to show everyone she's the best fencer. After the duel, Marinette; the referee, unsure how the battle ended, due to Kagami chasing Adrien around and battling roughly, declares Adrien the winner, much to Kagami's dismay and humiliation, causing her to depart from the school. Hawk Moth akumatizes Kagami, and turns her into "Riposte", a silver armor samurai villain with the power to slice and cut anything in half with one armed saber. To make matters worse, Adrien hurts his leg and has to cover it while helping Ladybug as Cat Noir at the same time without revealing his identity.
