Childhood friends Aoi Satsuki and Arata Uzuki are tasked with producing a fan event as part of a TsukiRadi project. Aoi, the considerate and kind prince of Gravi, selects "adventure" as the event's theme.

Believing adventurousness to be something he lacks, Aoi works extra hard to come up with an event concept with Arata. The answer they arrive at is a puzzle/escape room at the zoo that will give guests a taste of the extraordinary. The younger members take on the role of the guests as they begin rehearsing for the event!
Finally, I have a question about 
the Brown Bear Forest puzzle.
أخيراً، لديّ سؤال حول أحجية

Kommen wir noch einmal auf

Para cerrar, sobre el acertijo
del bosque de los osos.
