[Match Until End] Chairman's "watakushi" splits the group in half and forces round 2

The Concerto Day 1 group takes on the "Match Until End" challenge. During the leader-deciding round, the Chairman drops "watakushi" and throws the group into chaos. Next, the "main dish" round splits them perfectly in half between "udon" and "monja," forcing them back to the first topic for a second round that still refuses to end.
