Broken Wing is a mission in Red Steel. It's the fifth level in "Act 1: Sato's Legacy".
On a mission to stop Ryuichi and rescue Miyu Sato, Scott Monroe stows away in a truck and follows Ryuichi to an airport. While there, Scott finds out that Ryuichi is taking Miyu to Japan along with the weapons. Scott battles his way through the airport only to become injured when facing Ryuichi. Ryuichi leaves Scott alive to give Isao Sato a message: give him the Katana Giri or he'll never see Miyu again. Leaving Scott injured at the airport, the plane takes off, headed for Tokyo.
