School Trip Rhapsody (1)

Summary
On Bossun's bus, the gang is singing karaoke while Tsubaki remembers how he got stuck here with Sket Dan due to drawing lots. Meanwhile, Saaya overhears two girls' conversation about how couples are formed during this trip. Once someone mention Bossun, Saaya gets startle a bit when Chiaki offers her Monsoon chips. Saaya could not ask Chiaki about Bossun, and during the 20 minute break, she spots Hime and Bossun heading to the convenience store. Switch finds Saaya and greets her only to get yell at by Saaya. Saaya asks Switch what does Bossun think of Hime, and Switch replies that it's not a romantic relationship, but he doesn't know for sure. He tells Saaya to asks Bossun directly, yet Saaya gets flustered by this.

Back on the bus, Himeko gets car sick and asks Chuma for medication, and Chuma has his scary pill case full of drugs that he used in previous chapters. He has Bossun and Tsubaki test out the Soul Swap drug while Hime takes the motion sickness drug. Tsubaki and Bossun pass out, and Tsubaki wakes up and acts as Bossun. For Bossun, he wakes up and freaks out how he is in Bossun's body after looking at Hime's body. Hime wakes up and states that she's Bossun.

It turns out that Bossun and Himeko switch bodies because Tsubaki has taken the hypno drug while the two have taken the Soul Swap drug.
