In what has somehow become tradition, here is Westerberg High's Sexual Education Instructor, Ms. Nemu Kurotsuchi.

She's blunt, she has little to no social skills, but she both scare the crap out of students with knowledge of the dangers of STDs, while also being somehow capable enough to answer questions like "but how do I get the condom on without using my hands". Your go-to for the free contraceptives and sexual advice, with the obligatory "but abstinence is what you should probably try for" disclaimers.

Club wise, though, she'd be involved in science clubs! As either an adviser, or an assistant-type thing.
