Episode Title:Assembly Time.Episode Description:Manami Okuda attempts to poison Koro-sensei, but to no effect. She has poor communication skills, but she has a passion for chemistry. Because of this, Koro-sensei offers to help Manami make an effective poison. However, it turns out to be a tonic that transforms him into a speedier liquid form, teaching Manami to improve her communication skills so she can successfully deceive him someday. Later, the students of Class 3-E are forced to travel from their old campus and head to the main campus to endure a school assembly. The students from others classes become envious due to the students of Class 3-E having Karasuma and Irina as cool teachers. Koro-sensei shows his support by disguising himself as a scholar, providing extra copies of handouts previously not given to Class 3-E. Afterwards, Nagisa manages to use his experiences in Class 3-E to handle himself against Nobuta Tanaka and Chōsuke Takada, two bullies from the main campus.
