Chapter 31 — Destination: Okinawa

Framed as an embezzler, Eikichi promises to make it up to all of the 3rd year students with a trip to Okinawa. He claims that he can pay for it with a winning lottery ticket (obtained as a collateral from Saejima), but when he finds out that the ticket was a fraud, he has to find another way to pay for the ¥8 million trip.
