Kiyotaka and Aoi attend the birthday party of a famous appraiser. As part of the entertainment, their host asks Kiyotaka to identify a painting. But the "game" comes with a secret message...
If you think they're real, 
raise the white flag.
،إن كنتم تظنّون أنّها حقيقيّة
.ارفعوا العلم الأبيض
Falls Sie denken, dass es echt ist,
zeigen Sie die weiße Fahne.
Se acham que são verdadeiras,
usem a bandeira branca.
Считаете их подлинными — 
поднимите белый флаг.
