With the Chess Olympics just weeks away, the Japanese Chess Federation has decided to hold a tournament to determine the members of it's women's team. However, the venue for it is not yet secured, thus Mimoko and Daria must head to Tokyo's famous restaurant, mall, and resort, Ryokoma, in order to convince the owners to let them hold the tournament there and open up a new secret puzzle cafe there as well. Kuon, meanwhile, is furious at the JCF's sudden decision as with her position on the women's no longer guaranteed, her masterplan is now in jeopardy. Just who will make the team?
