Summary

Manami Okuda, whose knack for chemistry far outpaces her ease around people, tries once again to slip a poison into Korosensei, and once again it does nothing. Rather than scold her, he offers to help her cook up a formula that could actually work. The mixture they produce is no killer at all but a tonic that speeds him up and loosens him into a fluid state, and the real payoff is his coaching: he pushes her to sharpen her communication so that one day she might fool him into drinking the genuine article.

Key Events

Later, Class 3-E is made to trek from its hillside campus down to the main school building for an assembly. Students from the other classes look on with envy, since the outcasts of 3-E get to study under teachers as striking as Karasuma and Irina. Korosensei quietly backs his pupils by posing as a scholar and handing over spare copies of materials that had been withheld from them. By the end, Nagisa draws on what his time in 3-E has taught him to hold his own when the main-campus bullies Nobuta Tanaka and Chosuke Takada try to push him around.

Notes

The episode first aired on February 13, 2015, and adapts Chapter 7 and Chapter 11. Two moments were added for the anime that the manga never included: an opening in which Isogai and Kataoka help Korosensei haul chemistry gear while Maehara, Okajima, and Mimura attempt to stab him during setup, and an expanded look at the class's journey down the mountain to reach the assembly.
