Dark Knight

Dark Knight (ダークナイト) is an armored spirit in the form of a black knight.

Biography
Trained in the art of swordsmanship, he is able to display his fighting prowess in any situation. When summoned in large numbers, their coordination is enough to fight even the best of the best. It can be used as a diversion, a raid, or a decoy.

VIGILANCE LEVEL
One of the features of dark knights that have been summoned as bodyguards is that, in exchange for spending many times more mana than a normal dark knight, the summon duration is extended and the number of times they can revive increase.

Furthermore, in the event they are defeated, they automatically perform an analysis and revive with a more suitable weapon.
