Kurea and Luluka begin attending high school at Minato Mirai Academy. Their new classmates try striking up a conversation with Luluka but she's unable to respond well. Just then, she notices a love letter on the floor of the classroom.

Anna and the others enter a bookstore in the shopping arcade in pursuit of a Makoto Jewel. As they work to deduce the whereabouts of the shopkeeper's stolen gold medal, a conversation with a high school girl named Haruna Makifusa, who happened to stop by, provides them with a valuable hint.

Usonoir and Nijee steal Makopyon, a mascot suit for the shopping arcade with a Makoto Jewel inside, and run away from Anna and the others. Then, they disguise themselves as customers and duck into Patisserie ChuChu to wait until the heat is off.
