One day during lunch break. At the school store, Ruggie had successfully secured the highly popular Deluxe Menchi-katsu on an errand for Leona. However, he realized the bread he wanted for himself had been taken. (That's a problem-ssu...) Just then, he noticed Guest holding the bread he was eyeing. He instantly bought a random egg sandwich and skipped over to Guest with a cheerful air. Would you mind swapping that bread for this, -ssu?

Whatcha hiding there, -ssu? Here we go... "Laugh With Me!" He chants his Unique Magic in such high spirits he sounds like he's singing, forcing Guest to mimic his movements and successfully completing the trade.
