Episode Title:
Let Live Time.
Episode Description:
Despite getting hit by the math workbook, Koro-sensei manages to finish other subject workbooks without setting them off, having memorized all the problems beforehand. Left with the final workbook containing the real grenade, Gakuhō recalls his time as a kindhearted elementary teacher at a private cram school for his students Rikuto Ikeda, Mori and Nakai. Three years after these students moved onto junior high school, Gakuhō was shocked to discover that Ikeda committed suicide as a result of bullying. This led Gakuhō to change his teaching approach from kindhearted to ruthless. In the present, Koro-sensei protects Gakuhō from the real grenade, revealing that he bases his teaching methods in Class 3-E on Gakuhō's old stance on education. Gakuhō reflects on this, allowing Class 3-E to continue and aiming to become a better educator and parent. Afterwards, Class 3-E puts on a unique play about Momotaro for the drama festival.
