Matsunaga (松永) is a minor faction in Sengoku BASARA.
Matsunaga's forces are exclusively mercenary. They consist of spearmen, samurai, arquebusiers, wagons, suicide bombers, and shinobi.
Upon encountering him in Conquest Mode, he will try to break the gates and abduct the enemy's warriors to distract them.
In Heroes/Gaiden Mode, he deploys Miyoshi Trio in several missions.
