The first years are invited on a tour around the campus and a picnic. Tadayasu spots harmful bacteria in the food and saves everyone from E. coli food poisoning.

Professor Itsuki holds a celebration for Kaoru and Takuma getting part-time jobs, and during this party introduces everyone to the foul-smelling surströmming. Later, Haruka is summoned to a private dinner with her father and fiancé, but gets Kaoru and Takuma, who had actually been working at the restaurant before getting fired by Haruka minutes before, to think of something to get her out of the dinner. They call Tadayasu who brings a can of surströmming; once the can is opened, Kaoru and Takuma take Haruka out in the confusion and go to a bar.
