Ep. 18: Aquarium staff prepare for a sea creature cosplay event despite Akari's exclusion

Akari proposed a cosplay event where staff dress as sea creatures to greet visitors, which was approved. However, Tetsuji Suwa assigned Kukuru and Karin to lead preparations instead of part-timer Akari. Kukuru attempts to foster Akari's interest in the aquarium's animals, but Akari remains uninterested. On the eve of the event, a critical error is discovered: the fish stickers intended for distribution have not yet been ordered. This oversight threatens the event's success just before it begins, leaving the assigned staff to deal with the missing promotional materials while Akari continues to show no enthusiasm for the aquatic theme.
