Bento boxes for lunch are quite popular at Mizuhosaka Academy's. Yuma's mother-in-law, Otoha, who works at Oasis, the school's cafeteria, has been worried about the lack of customers. That's when Anri started working there part-time as a waitress. She put all her time and energy in handing out pamphlets and such in order to drive in more customers but all her hard work didn't seem to pay off.
Wh-What's so funny?
