Members of the class are chivalrous female warriors with skills both as swordswomen and magicians and are said to be able to see into the future using a power called "Zone". They also seek the universal truth and they frequently communicate with Professors due to their shared interest. Magic Knights all follow "the Sword's Oath", and breaking the Oath is punishable by death.
Their preferred weapons are swords and staves, as they are able to effectively use both physical attacks and elemental magic. They also have a innate ability which allows them to cast a random spell after performing a physical attack.

In Disgaea 2: Cursed Memories the Knight class was renamed Magic Knight, presumably to make them distinct from the Heavy Knight class. They also gain additional abilities to make them more than just a Valkyrie who can cast magic. The class is obtained by having a Level 3 mastery in both swords and staves then passing the "Make a Busty Beauty" bill in the Dark Assembly.
