Defense(守り) is a stat in Nage Libre Seijaku no Suishin. It is one of the key stats to survival more so than HP. For every point of Defense the character has, the less damage they will take. Another way to increase defense is through the use of a Defence Card which is essential for frail characters like Ayaka or Mai, who need the boost when up against enemies or bosses with high attack. Some characters have very high natural defense such as Ryoko and Miki. Ryoko having the highest defense, occasionally takes no damage from enemies that attack her. It will also effect how well the Defence Card will work.
