Koro-sensei was the mentor who touched my heart the most 💔 Although at the beginning of the story he was seen as the main antagonist, as the story progressed he left many messages and teachings to his students, he guided them and strengthened them so that they would know what to do when the day of the end came.

He taught them not only to save the world, but values of life and showed them that his students were not the weird ones, but that they were special and had a value that they themselves could not see 😢❤️ he was an excellent teacher for all those children.
