As Koro-sensei struggles against both Yanagisawa and the Reaper, he takes further damage as the Reaper directs his attacks towards the students. Hearing Koro-sensei's kind words in his students' defense after Yanagisawa claims them to be hindrances, Kaede attacks the Reaper, but is fatally injured in the process, seemingly sending Koro-sensei into a rage. However, his true expression turns out to be a mix of all of his emotions, giving him the power to kill both Yanasigawa and the Reaper, who had wanted all along to be acknowledged by his teacher. Afterwards, Koro-sensei, having managed to keep Kaede's blood safe during the battle, uses his skills to heal her injury and bring her back to life.
