The time has come for that hallmark of high school life: the school trip. Yoshiko’s class will be visiting the balmy southern isle of Okinawa. Yoshiko’s deeply interested in the fascinating history and culture of the Okinawan islands, so she’s excited to go. Nah, just kidding, she doesn’t even know where Okinawa is, and she’s only excited because some fool told her there were good bananas there. Classic Yoshiko.
