Ep. 3: Lala's inventions cause body swaps and accidental massages for Rito, Haruna, and Tearju.

3

Lala's scattered inventions trigger chaos as Rito and Haruna swap bodies for seven hours. While Rito in Haruna's form gets covered in mayonnaise, Haruna in Rito's body must clean up, causing them to touch when the timer expires. Meanwhile, Celine plays with a broken device that turns out to be a massage tool. It activates and forces Tearju Lunatique to receive unwanted massages, leading to her limping. Rito offers to take her to the sickroom, but the device continues its violent caresses, causing Tearju to fall on him. Yami witnesses this and assumes Rito is being inappropriate, attempting to kill him. The invention is later revealed to be a self-massage machine given to Honekawa for his back pain.
