With Medaka admitted to the hospital, Zenkichi, Akune and Kikaijima discuss about how Medaka influenced them in their lives. Sooner than later, Sasae Mochibaru, captain of the shogi club, requests the three to find a missing king shogi piece hidden somewhere in the messy shogi clubroom. When Mochibaru returns after the shogi clubroom is cleaned, it is realized that all sets of shogi pieces are missing the king shogi piece. Miri Natayama, a skilled shogi player, is considered a suspect in this crime of burglary, possibly because she left the shogi club for not being chosen as the captain of the shogi club, since she treated the beginners with disrespect. Zenkichi challenges Natayama to a game of shogi with only the gold generals, showing her that only a variation of shogi can be played without the king shogi piece. Akune explains that the king, also called the jade general, continues to fight in life's tough circumstances instead of running away. Natayama is content knowing that the student council still functions well even without Medaka being there to support. The missing king shogi pieces are later found inside one of the lockers in the shogi clubroom, perhaps by Natayama.
