The narrator and his friends are in the middle of the second round of the Master and Queen matches in shiga, a prefecture in northeastern Japan. They're talking about a girl named Mami, who's been playing competitive Japanese card games since she was a little girl. She's gained a lot of weight in the process, and they're worried that she's going to lose the match. The narrator compares Mami's slim figure to that of a colander, and wonders if she'll be able to hold her own in the tournament.
